Abstract in English:Abstract Popilius gibbosus (Burmeister, 1847) was known only from localities in the Cordillera Oriental of the northern Andes in Colombia and Venezuela and the southern section in Colombia between 1,350-3,000 m. Herein, we provide the first record for Bolivia at low elevations (< 1,000 m), thus extending the geographic and altitudinal range of this species. Information about characters not yet used and the first description of the aedeagus are provided, accompanied with figures of those characters that facilitate the identification of the species. An identification key for Popilius species in Bolivia and a P. gibbosus distribution map are also provided.
Abstract in English:Abstract This study aimed to compare the activity of ants during the rainy and dry seasons in a transitional environment (ecotone) at the interface of Cerrado and Caatinga biomes situated in the state of Piauí, where studies of local ant fauna are still incipient. The research was carried out at Floriano, state of Piauí, Brazil. Ants were sampled during the rainy season in December 2018 and during the dry season in June 2019. Three parallel transects were established at least 100 m apart. At each point, three sampling methods were used, with attractive baits placed on the trees and ground, and pitfall traps on the ground. Thirty-one ant species belonging to 14 genera and five subfamilies were collected, with 27 recorded in the rainy season and 17 in the dry season. The only species reported with the three collection methods and the two seasons was Camponotus crassus Mayr, 1862. Seven ant species sampled in this study are new reports for the state of Piauí. There was a significant difference in the average number of ants and the composition of the assemblages between the rainy and dry seasons. We demonstrate that the activity of ants is influenced by seasonality, corroborating our hypotheses. This is only the second study on ant diversity in the state of Piauí, and more studies are necessary to understand the processes and factors which regulate the activity patterns of ants in ecotonal situations like those observed in this region.
Abstract in English:Abstract We provide an update, based on literature records, on biodiversity and distribution of echinoderms along the state of Santa Catarina, Brazil. Sixty-one echinoderms taxa are reported, in 36 families. We present information on habitat distribution, taxonomy and possible threats to these species. The highest number of echinoderm records was between 25°19′S and 28°11′S latitudes, and sites of the Continental Shelf and the Reserva Biológica Marinha of Arvoredo area had the most species records (30 and 26 species, respectively). In addition, Santa Catarina is the southernmost record, in the Atlantic Ocean, for 40 echinoderm species; of these, 10 are on the regional list of endangered species. Eight species are endemic to Brazil and one ophiuroid species was reported herein for the first time at Santa Catarina: Ophiacantha pentacrinus Lütken, 1869.
Abstract in English:Abstract Here we present a three-year survey of amphibian and reptile species registered in the Vale Natural Reserve (VNR), located in the north of Espírito Santo, southeastern Brazil. The VNR, along with the Sooretama Biological Reserve (SBR) and other surrounding areas, form a forest block that constitutes one of the largest remnants of continuous forest in the Atlantic Forest biome. We systematically sampled the herpetofauna community from 2015 to 2018, using the method of active search method in 27 plots of RAPELD distributed in the different types of vegetation present in the area. We recorded 39 species of amphibians belonging to the order Anura, distributed in seven families and 40 species of reptiles belonging to 20 families distributed in three orders: Crocodylia, Testudines and Squamata. The supplementation the samplings with those records from occasional encounters was important for the survey of the region’s herpetofauna, mainly for reptiles. We added four species (two lizards, one amphisbaenid and one snake) to the known list for the VNR-SBR forest block: Micrablepharus maximiliani, Strobilurus torquatus, Amphisbaena alba and Tantilla sp. We demonstrated that VNR contains a high species richness of amphibians and reptiles, with a high number of anurans being endemic to the Atlantic Forest biome. The present species inventory provided the most current approximation of known the richness and composition of species of the existing herpetofauna at Vale Natural Reserve, since the period of the gathering of records is quite recent (2015-2018). Also, it brings the knowledge of some community parameters as species richness and composition not only for the whole area of the Vale Natural Reserve, but also for its different vegetation types, with no inclusion of environments outside this reserve. Furthermore, the presence of threatened species, the addition of four species to the current list, and the potential for new species to occur, reinforce the role of VNR as an important area for the protection of amphibian and reptile biodiversity in the Atlantic Forest.
Abstract in English:Abstract A new species of LeptophoxoidesBarnard, 1962 is described with material from the continental slope of Rio Grande do Norte state, northeastern Brazil at three different depths: 150, 400 and 2,500 meters. Leptophoxoides longisetae sp. nov. can be diagnosed and distinguished from the other two species of the genus, L. molarisBarnard, 1962 and L. marinaSenna, 2010, by the following characters: antenna 1 peduncular article 1 ventral apex weakly ensiform; maxilla 1 inner plate longer than outer; maxilliped palp article 3 with blunt and extremely protuberant apex; gnathopods 1-2 carpus almost cryptic; gnathopod 2 palm defined by a large and sharply produced palmar hump; pereopod 6 basis posterodistal corner produced as a blunt lobe; and telson with two dorsal long plumose setae on each side. This is the first record of the genus for northeastern Brazilian waters, uncovering a higher biodiversity in deep waters.
Abstract in English:Abstract Shrimp trawling is considered a significant negative impact on the marine ecosystem, especially on the benthic community. Sea stars (Echinodermata: Asteroidea) are one of the most affected groups by unintentional catches. This study was performed at the Santana Archipelago, a Marine Protected Area in the northern region of Rio de Janeiro State, between 2008-2009. Sea stars accidentally caught by trawling were collected during open and closed season of the shrimp fisheries (Xiphopenaeus kroyeri) at depths of 5-60 m. A generalized linear zero-inflated model was applied to test for differences in capture between fishing seasons and depths. A total of 158 sea star specimens were captured. These specimens were identified as Asterina stellifera, Astropecten acutiradiatus, Astropecten brasiliensis, Astropecten cingulatus, Luidia alternata alternata, Luidia clathrata, Luidia ludwigi scotti, Luidia senegalensis. The sea stars A. brasiliensis and L. senegalensis are currently considered as vulnerable species in the Brazilian official list of threatened species. The higher capture of sea stars was shown in deepest areas, and there was no significant difference in the number of specimens between seasons. This is the first study about asteroids accidentally captured by shrimp trawling.
Abstract in English:Abstract As most neotropical pipids, the four species of Pipa present in Colombia are poorly understood despite their particular biology. The tegument of these New-World pipids presents particular structures which variations have been hardly analyzed. Therefore, we aim to describe the morphological variations of the dermal flap, barbels, fingertips, and the lateral line pattern among these four species, focusing on changes during the ontogeny. The results of the study show that the dermal flap was exclusively found in P. pipa, while barbels are usually present in P. pipa but seldom in P. snethlageae. The lateral line pattern in the dorsum is shared by the four species, but P. pipa present more neuromast lines along the snout than P. snethlageae. These species were different from P. parva and P. myersi, which cannot be distinguished based on external morphology, as they were more similar in all lateral line elements and exhibited the same fingertip morphology. On the other hand, the fingertips of young individuals of P. pipa and P. snethlageae presented four simple distal lobes which bifurcate twice during the ontogeny, so that adults present sixteen lobes. The difference between species is observed in the fingertip morphology: P. pipa has all four lobes distally placed, but P. snethlageae has one pair more proximal. The tegument structures analyzed here have a taxonomic utility using external morphology for P. pipa and P. snethlageae, but for P. parva and P. myersi additional studies are necessary. For future research, evaluating the function and anatomy of these structures is important to the understanding these integumentary structures in Pipa.
Abstract in English:Abstract In the Attina subtribe the division of labor among workers is based on different tasks performed by morphological subcastes. Considering that cuticular chemical compounds play important roles as protection against water loss and mediates interactions between nestmates, and that studies on the cuticular chemical profile of ants of the genus Atta are still scarce, the aim of this study was to evaluate the relationship between morphological and chemical phenotypes in the subcastes of Atta laevigata (Smith, 1858) workers. The cuticular chemical composition of the different subcastes was assessed by Gas Chromatography coupled to Mass Spectrometry technique. The compounds found in the cuticle of the different subcastes had carbon chain size between 18 and 31 atoms, with higher content of linear alkanes in workers and soldiers and higher content of branched alkanes in gardeners and generalists, probably related to the type of tasks they perform in their colonies, since some workers perform more intra- or extranidal tasks in relation to others. The results show significant qualitative differences in the cuticular composition of the different subcastes, with a greater relationship between them according to the environmental restrictions that each subcaste is more subjected to due to the role played in the colony.
Abstract in English:Abstract The three new species of Brazilian Euplocania are described and illustrated, two species belong in the amabilis species group (Euplocania maraca sp. nov. and Euplocania ufrr sp. nov.) and one species belong in the marginata species group (Euplocania macuxi sp. nov.). Information on species groups, species subgroups and distribution by Brazilian states is included for known species of Euplocania.
Abstract in English:Abstract Vertebrates, overall, present a daily activity pattern when managing their needs, such as foraging, resting or searching for sexual partners. Most of the available information regarding the circadian rhythm in birds comes from controlled laboratory conditions, and little is known about these patterns in the wild. In this study we used camera traps to describe the daily activity patterns of three cracid species in the Pantanal of Rio Negro, Brazil. We had a sampling effort of 9,617 camera trap-days along 231 days (5,544 hours) from September 2013 to May 2014. This resulted in 4,833 independent records of cracids from a total of 7,713 individuals. Crax fasciolata was the species with the most records (nrec = 3,792) and individuals (nind = 5,781), followed by Ortalis canicollis (nrec = 934; nind = 1,758) and Aburria grayi (nrec = 107; nind = 174). None of the species was uniformly distributed throughout the day, thus evidencing a periodization of their activities. The mean vectors of the activity patterns of C. fasciolata, O. canicollis and A. grayi were, respectively, mμ = 10:36 ± 04:26 (SD), mμ = 11:42 ± 03:57 and mμ = 11:44 ± 03:47. We observed a temporal overlap between A. grayi and O. canicollis, whereas C. fasciolata significantly differed from them. Because of their large home ranges, cracids are important indicators of environmental quality, and, as frugivores, they play key roles in the ecological dynamics of forests. In this sense, and given that cracids are notably more susceptible to extinction, the knowledge on their circadian activity patterns may be useful when establishing effective management and conservation strategies.
Abstract in English:Abstract Despite being the most diverse family of flies found in carcasses and corps in the Neotropical Region, Sarcophagidae is still underestimated in Peru. This research was developed in the Department of Piura, Northern Peru and we identify the flesh flies captured on two kinds of animal carcasses: dog and guinea pigs. As a result, a new record was documented for Peru: Blaesoxipha (Gigantotheca) plinthopyga (Wiedemann, 1830) and eight new records for the Department of Piura.
Abstract in English:Abstract As a result of environmental change by anthropic action, animal species that inhabit these areas may suffer the effects of it on their phenotypes as a consequence of adapting to these conditions. In the case of social wasps, cuticular chemical compounds may be influenced, since these vary depending on genetic and environmental factors. However, few studies have investigated the synanthropic effects over the cuticular surface of social wasps. Therefore, the aim of this study was to investigate how cuticular compounds vary according to the different degrees of human activity and test the hypothesis that cuticular compounds of social wasps are affected by the level of anthropic activity in which their nests are found. Data on the cuticular chemical compounds composition of colonies of 3 species of social wasps were used along with the level of anthropization of their nesting sites in four municipalities in the state of Mato Grosso do Sul, Brazil. From the geographical coordinates of the sampling sites, the percentages of urban construction areas, agriculture, water body, vegetation and exposed land were calculated, and the nesting sites of the colonies were classified as more or less anthropized areas. The chemical profile was determined by extraction of cuticular compounds and analyzed by Gas Chromatography coupled to Mass Spectrometer (GC-MS). The results show that the cuticular chemical composition of the individuals of these species is affected by the level of anthropization in their nesting sites, with a qualitative and quantitative variation that must be tied not only to genetic differences, but, above all, to the local environmental conditions to which their colonies are subjected.
Abstract in English:Abstract Roraima is a Brazilian state located in the northern portion of the Amazon basin, with few studies regarding its biodiversity. The Ecological Station of Maracá (Brazil, state of Roraima) harbors the third largest Brazilian pluvial island and is composed of a transitional landscape of savanna and Amazon rainforest components. Despite its ecological importance and strategic localization, few studies covered the dipterofauna of this locality. An updated checklist addressing 41 families of true flies (Diptera) occurring in Roraima is presented based on the literature and the specimens collected during a field expedition that occurred in 2015. This checklist brings several improvements such as new records of 165 taxa to the state of Roraima, 29 taxa to Brazil, and 259 morphotypes, mostly likely representing undescribed species.
Abstract in English:Abstract The types of nominal species of Echinodermata in the collection of the Museu de Zoologia, Universidade de São Paulo are catalogued: Holothuroidea (19 species - 16 holotypes, 1 paratype and 2 neotypes) and Ophiuroidea (4 species - 1 neotype and 3 paratypes). Photographs of all the type specimens are given. A brief account of the history of the MZUSP’s echinoderm collections is presented.
Abstract in English:Abstract Ecological and life history traits have been used to understand the basic ecology of fishes. This study aimed to examine the existence of plasticity in life history traits of populations of Hollandichthys multifasciatus in ten blackwater streams. This is an inseminating Characidae, endemic to the Atlantic coastal drainages of Brazil. Different aspects of the life-history of the species, such as mean length, sex ratio, absolute and relative fecundity, gonadosomatic index, condition factor, length-weight relationship and the growth parameter (b) of 185 specimens were studied during the period of low precipitation (June-September). Fish samples were obtained along a 100 m stretch of each stream, and some habitat variables recorded. ANOVA and Kruskal-Wallis tests indicated a similarity in most of the analyzed traits, with exception of the mean length of immatures, Gonadosomatic Index of mature males and condition factor of immatures and mature adults. Also, slope tests of the length-weight relationship were significantly different for immatures. The observed differences were attributed to heterogeneity in food availability and/or other site-specific factors, which may influence growth and/or breeding aspects among the studied localities. The approach used herein may improve understanding of trait plasticity under natural conditions, helping to understand fish-community responses to anthropogenic changes.
Abstract in English:Abstract The seasonal forest formations of the Atlantic Forest are a threatened and poorly known habitat. We present here a list of the non-volant mammals occurring in a 515-ha forest fragment known as Santa Maria and located in the Brazilian state of São Paulo. Our surveys are based on live trap captures, camera traps, and active searches for footprints, as well as secondary data. We list 29 species of non-volant mammals in the fragment, recorded between 1996 and 2021. One species found in the fragment, Leontopithecus chrysopygus, is globally endangered. Two species are classified as “vulnerable” in the global red list: Myrmecophaga tridactyla, and Tapirus terresris. One species, Panthera onca, is classified as “critically endangered” in São Paulo state. The red howler, Alouatta guariba, was not recorded after 1999 and has probably been extirpated in the fragment. We show that the number of non-volant mammal species in Santa Maria fragment is high, in relation to its size. The fragment is also in a strategic position, between the Morro do Diabo state park and the Black Lion Tamarin Ecological station, the two largest protected areas in the region. Considering its high mammal richness and its possible role as stepping stone for the local fauna, we recommend that the fragment become a protected area.
Abstract in English:Abstract Although communication capabilities are displayed by many vertebrate groups, some repertoires are poorly known, such as the case of xenarthrans, particularly armadillos, for which vocalization as a source of communicating to others remains poorly understood and relies on punctual reports of sounds. Here we provide the first description of a behavioral response associated with sound emission of two subjects of Dasypus novemcinctus. Both audio and visual registration was performed to subsequent analyses of expressed behaviors and emitted calls, which accounted for 76 vocalizations from a total of eight video recordings randomly collected from 2017 to 2019. Sound is acoustically characterized by both inhale and exhale phases composed of two vocal units, and no harmonic structure was observed. Once the subjects have always produced these vocalizations while cornered and exhibiting defensive behavior against another subject/human disturbance, these vocalizations were termed as distress. Subjects produced a hiss-purr-like sound while trying to avoid contact with another by bowing or lowering their bodies, humping, or even moving elsewhere when sound production ceased. This shows that the sound repertoire of armadillos is still to be unveiled and seems to be much more complex than previously thought.
Abstract in English:Abstract Bats frequently feed over water bodies, but the net value of the water bodies depends on characteristics such as the amount of physical clutter the water body has. More physical clutter may reduce the detection of prey by bats and may also increase energetic costs by increasing in the number of obstacles to avoid. Consequently, we hypothesized that increasing physical clutter affected the use of an artificial pond where the Lesser Bulldog Bat Noctilio albiventris, a Neotropical fishing bat, forages regularly over water. We experimentally tested this idea recording the number of passes and feeding buzzes emitted by the bats on different nights when we added two levels of obstacles over the water and on control nights with no obstacles. We only found differences between the treatment with the highest obstacle density and the control; there were fewer passes and less feeding buzzes with more obstacles. Therefore, the addition of obstacles did affect the foraging behavior of N. albiventris. Furthermore, we suggest that increasing physical clutter, as in our experiments, may be a cost-effective way to reduce conflicts between local fisher farmers and fishing bats in Neotropical rural areas.
Abstract in English:Abstract We report a case of male corpse colonization found inside a residence in the municipality of Areia, Paraíba, Brazil. The body was found in the gaseous stage of decomposition and was colonized by fly larvae. We reared the larvae collected at the crime scene on a temperature-controlled. We supplied beef as a feeding substrate for the larvae until adult emergence to allow taxonomic identification. Three specimens of Peckia (Squamatodes) ingens emerged in the laboratory. Thus, we present the first record of the flesh-fly Peckia (S.) ingens colonizing a human corpse in Neotropical region, updating the list of species with forensic potential. In addition, information on the total time of the species development and the implications of these findings for the consolidation of forensic entomology in the Northeast region were discussed.
Abstract in English:Abstract Acanthoderes crocostigma Bates, 1880 is transferred to AcakyraMartins & Galileo, 1996. Acanthoderes umbrata Bates, 1885 is synonymized with Acanthoderes purulensis Bates, 1885. Variation of the elytral pubescent pattern in Aegomorphus longitarsis (Bates, 1880) is reported, and the species is recorded for the first time from Colombia (Boyacá) and Brazil (Amazonas). The variation of the elytral pubescent pattern in Aegomorphus doctus (Bates, 1880) is reported, and the species is recorded for the first time from the Mexican state of Jalisco. We comment on the type-locality of Aegomorphus borrei (Dugès, 1885). Two new species are described from Mexico (Jalisco): Aegomorphus cunninghami and A. nogueirai.
Abstract in English:Abstract The genus Plega Navás, 1928, belongs to the subfamily Symphrasinae, a group recently transferred from Mantispidae to Rhachiberothidae. This genus is herein reported as parasitoid of the symphytan family Diprionidae for the first time, becoming the first record of association between this neuropteran subfamily and non-aculeate Hymenoptera. This new association was discovered in “Ixcateopan de Cuauhtémoc”, in the Mexican state of Guerrero, where Plega spinosaArdila et al., 2019 was found associated with immatures of the sawfly Monoctenus cuauhtemoci De Lira, 2021, a pest in forests of Juniperus flaccida Schlechtendal (white cedar). The neuropteran was found to be the most abundant parasitoid of this symphytan, becoming a potential candidate for biological control of phytophagous sawflies in juniper forests, an economically important plant species for the wood industry in the region. Considering the behavior and morphological aspects of the primary larvae and the behavior of the adults of Plega, three possible scenarios in which the primary larvae of P. spinosa board the larvae of Monoctenus to complete its life cycle are outlined. This finding reinforces the hypothesis of a generalist ectoparasitoid lifeway of the larvae of the genus Plega on larvae and pupae of holometabolous insects.
Abstract in English:Abstract In the systematics of cnidarians, the different types of cnidocysts are considered an important taxonomic character. In Hydra, the four types of cnidocysts found in the ectoderm, concentrated in tentacles and their measurements, together with other morphological and reproductive characteristics, are very important for the taxonomy of the species. In this study, we explore in detail the biometric and statistical characteristics of the cnidome of three species of Hydra collected in three different environments for each climate season. A total of 17,378 capsules were measured. We used ANOVA test and Generalized Linear Model to analyze the distribution and differences reflected in each cnidome, considering the factors “individuals”, “season”, “lagoon” and “species”. The results were clear: the cnidome keep specific information that, together with other taxonomic characteristics, allows us to discern between species of different groups. The same happens with cnidome of the same species but from different lagoons or climatic seasons: we observed a variation of parameters for each type of cnidocyst that could differentiate “ecological races”, since these differences are not enough to declare different species.
Abstract in English:Abstract We provide a taxonomic note on Paedarium Aldrich, 1926, with new generic synonyms, Neopaedarium Blanchard, 1943 syn. nov. and Velardemyia Valencia, 1972 syn. nov., and new combinations resulting from these synonyms, Paedarium ica (Valencia, 1972) comb. nov. and Paedarium subauratum (Blanchard, 1943) comb. nov. Paedarium punctipennis Walker, 1857, is considered an unplaced species of Voriini. A redescription of P. subauratum and notes on its biology are given. A key for species of the genus Paedarium is provided.
Abstract in English:Abstract The present study aimed to increase knowledge about the diversity and factors that determine the distribution of galling insects in the Parque Nacional do Itatiaia (PNI), Southeast, Brazil. For this, collections were performed in April, August and November 2015 and March 2016. Seventy gall morphotypes were found in 12 families, 32 genera and 61 species of host plants. The richness of galls did not vary with altitude, but increased with the richness of plants. The families and genera of plants with greater species richness harbored a greater number of galling insects. The number of gall morphotypes was higher in the autumn than in the other seasons. The spatial distribution of galling insects was better explained by factors such as floristic richness and species composition than by ecological effects, represented here by altitude. Regarding seasonality, the results indicate that the way resources are temporarily distributed to galling insects depends on factors such as the active growth of host plants, making some periods of the year more conducive to the development of galls.
Abstract in English:Abstract Mixed flocks are associations of two or more species that are formed and maintained through mutual behavioral responses, with advantages such as maximizing foraging and protecting against predation. This study aimed to evaluate the composition, temporal dynamics, and presence of core species in mixed flocks of birds in a remnant of the Submontane Atlantic Rain Forest in the Parque Nacional Aparados da Serra, southern Santa Catarina state, Brazil. Data collection took place from October 2016 to September 2017 through monthly campaigns, consisting of three consecutive observation days, with sampling sessions of six hours per day, resulting in a total effort of 216 h of observations. For each contact with the flocks, we recorded the species and number of individuals, stratum of occurrence, substrates of search, and agonistic interactions. We recorded 152 mixed flocks, with a total of 76 species belonging to 24 families, and five orders, with Thraupidae, Tyrannidae, Furnariidae, and Rhynchocyclidae being the richest. The flocks had an average of 4.5 ± 2.7 species and 8.7 ± 5.8 individuals, with richness and the number of individuals being positively correlated (R² = 0.8). Mixed flocks occurred throughout the year. There was a great variation in the number of contacts from October to February (from 5 to 20 contacts). Meanwhile from March to September, the coldest period of the year in the region, the number of contacts did not vary (from 9 to 14 contacts). However, there was no difference in the number of contacts between these months (z = 0.37; p = 0.691). Basileuterus culicivorus and Habia rubica were the core species because, in addition to their high participation (46.7 and 32.9%, respectively), they showed frequent and conspicuous movement and vocalization. Thus, a high capacity to enlist a greater number of individuals from different species for the flocks was demonstrated.
Abstract in English:Abstract New records for Eupogonius flavocinctus Bates, 1872, E. boteroi Wappes & Santos-Silva, 2020, E. azteca Martins, Santos-Silva & Galileo, 2015, E. subaeneus Bates, 1872, E. guerrerensis Wappes & Santos-Silva, 2020, and E. arizonensis Knull, 1954 are provided. Eupogonius sonorensis Wappes & Santos-Silva, 2020 is synonymized with E. arizonensis. The synonymy between E. pauper LeConte, 1852 and Eupogonius fraxini Knull, 1918 is commented. Two new species are described: Eupogonius rileyi, from Costa Rica; and E. similis, from Guatemala.
Abstract in English:Abstract This study represents an inventory of fish collected in a first order tributary of the Igarapé Piracolina at Chapada dos Parecis, upper Rio Machado drainage, Rio Madeira basin, Vilhena, Rondônia, Brazil. The sampled stream is located in moderate altitudes (570-590) m above sea level and it is the type locality of five recently described species. Through fieldwork carried out in four fieldtrips between 2014 and 2015, 966 specimens were captured belonging to 18 species, distributed in nine families and four orders. Most of these species have a restricted distribution in the upper Rio Machado. Characidae was the most representative family both in number of species and specimens. One species is recognized as new and endemic to the region, and belong to the genus Pyrrhulina (Lebiasinidae), while five other species (Ancistrus verecundus, Bryconops piracolina, Hyphessobrycon lucenorum, Moenkhausia cambacica, and M. parecis) are also possibly endemic to the upper Rio Machado basin. In this scenario, our results provide relevant data for the establishment of guiding policies, management decisions and bases for conservation actions in moderate altitude areas of the Amazon basin.
Abstract in English:Abstract Several phytogeographic regions (Cerrado, Pantanal, Atlantic Forest, Gran Chaco, and Chiquitano Dry Forests) converge in the state of Mato Grosso do Sul, Brazil, and influence regional biodiversity. Despite a list of birds in the state of Mato Grosso do Sul being published by Nunes et al. (2017), it is necessary to update and critically review avifauna records. In this study, we gathered the results of several records obtained from species lists and online data platforms of the 336 sites in this state over the last decades and grouped them into Main (Primary and Secondary) and Tertiary Lists. The avifauna of Mato Grosso do Sul is composed of 678 species, of which 643 (95%) have records proving their occurrence (Primary List), whereas 34 still lack documentation (Secondary List). The number of related species for Mato Grosso do Sul represents 34% of the Brazilian avifauna. Some species stand out for their unique occurrence in Mato Grosso do Sul, such as Melanerpes cactorum, Celeus lugubris, Phaethornis subochraceus, and Cantorchilus guarayanus, reflecting the influence of different phytogeographic regions of the Chaco and Chiquitano Dry Forests. Migrants represent 20% of the bird community occurring in the state, of which 93 species correspond to migrants from various regions of South America (south and west) and 40 to boreal migrants. Thirty-three species perform nomadic movements across the Pantanal Plain and other regions of the state. Thirty-one species are included in some conservation-threatened categories of global and/or national endangered species lists. Other 30 species are included in the near-threatened category at the global level and 23 at the national level. In addition, species typical of dry forests (in Serra da Bodoquena and Maciço do Urucum) and those from the Atlantic Forest in the south of the state deserve attention due to their restricted distribution and the high anthropogenic pressure on their habitat.
Abstract in English:Abstract Eurysthea vandenberghei, new species from Nicaragua is described, and E. vandenberghei Santos-Silva, Heffern & Botero, 2021 is considered a nomen nudum.
Abstract in English:Abstract Knowledge of the reproductive biology of Bare-faced Curassows (BFC) from their natural habitats is very limited. Our study covers a two-and-a-half year breeding phenology on BFC in the northern Pantanal (Mato Grosso State, Brazil) with the main objective of collecting information on reproduction biology to contribute to future conservation management strategies of this cracid, which received a recent status of “High Conservation Priority”. The study was conducted at the SESC Pantanal, Baía das Pedras, Mato Grosso, Brazil (16°29′55″S, 56°24′46″W), a private protected area of approximately 4,200 ha. Between July 2015 and December 2017, 37 sampling locations were monitored with camera traps placed in a regular grid with a spacing of 1 km. Offspring were detected at least once at 8 locations, namely, in March, April, and May 2016 and in June, July, October, and November 2017, always together with parent(s). Territorial overlap between different family groups was detected. The camera trap dataset was supplemented by data from Citizen Science Projects (i.e., eBird) and the Global Biodiversity Information Facility (GBIF). Based on feather developmental stages and body size, offspring were classified into different age classes. Age determination indicates that breeding occurs year-round in the northern Pantanal region, supported by eBird and GBIF data. The use of a grid-based design for future camera-trapping studies of BFCs is strongly recommended. Our study is of biological relevance for conservation management projects since data were collected in an area with low anthropogenic disturbance and intact ecosystem services.
