  • Feeding and diet rythms of Metynnis roosevelti Eigenmann (Characidae, Myleinae) at Jiqui Lake, Parnamirim, Rio Grande do Norte, Brasil

    Canan, Bhaskara; Gurgel, Hélio de Castro Bezerra

    Abstract in English:

    The goal of this study is measure the food ingestion by M. roosevelti Eigenmann, 1915 emphasizing its feeding rhythmic. The observations were made between March 1994 to February 1995, in Jiqui Lake, Rio Grande do Norte State. The sample involved 1115 individuais, including 503 males and 613 females, collected in five waiting-net with length of 5.0 to 5.0 m and mesh of 2.0, 2.5 and 3.0 cm between opposites joins, that were exposed for 24 hours and reviewed each 6 hours. The food ingestion was predominant between 6:00 AM to 12:00 AM for males and between 6:00 PM to 12:00 PM for females. The condition factor showed lower values between 6:00 PM to 12:00 PM for males and between 12:00 PM to 6:00 AM for females. The mean level of repletion showed higher values between 12:00PM to 6:00PM for males and between 6:00 PM to 12:00 PM for the females. The higher levels of repletion index for males were observed between 12:00 AM and 12:00 PM for the females and between 6:00 PM to 12:00 PM for males. For this species, plankton constituents, specially algae, are its preferential food.
  • Effects of environmental degradation on Odonata community of Atlantic Forest streams from Minas Gerais, Brazil

    Ferreira-Peruquetti, Patrícia Santos; Marco Jr., Paulo De

    Abstract in English:

    The effect of riparian deforestation and stream impoundments on an odonate community was studied in áreas of surviving Atlantic forest in Viçosa and in Rio Doce State Park (PERD), Marliéria, Minas Gerais, Brazil. During 1997 16 species of Libellulidae, 4 Coenagrionidae, 2 Gomphidae, 2 Calopterygidae, 1 Megapodagrionidae, 1 Aeshnidae and 3 Protoneuridae were collected. In Viçosa, the association of sampled odonates with lotic or lentic systems, and in PERD for areas with or without riparian vegetation were compared. The results suggest that although overall odonate taxonomic richness is high in areas without riparian vegetation. Likely, because productivity increase of such areas and its invasion by lentic Odonata species.

  • Composition of the flatfish population (Osteichthyes, Pleuronectiformes) in the Sepetiba Bay, Rio de Janeiro, Brazil

    Mendonça, Pablo; Araújo, Francisco Gerson

    Abstract in English:

    Bi-monthly otter trawl sampling programme using a stratified random design was carried out at Sepetiba Bay (22º54'-23º04'S; 43º34'-44º10'W), from August 1994 to July 1996, aiming to assess the flatfish species composition and their relative abundance. Fourteen species in eight genera, four families and one suborder were identified. Paralichthyidae is the most diverse and abundant family, contributing to 70% of total number of individuals and to 58,8% of total biomass, being comprised of nine species: Etropus crossotus (Jordan & Gilbert, 1882); E. longimanus (Norman, 1933); Citharichthys spilopterus (Günther, 1862); C. arenaceus (Evermann & Marsh, 1902); C. macrops (Dresel, 1889); Paralichthys orbignyanus (Valenciennes, 1847); P. brasiliensis (Ranzani, 1840); P. patagonicus (Jordan, 1889) e Syacium papillosum (Linnaeus, 1758). Etropus crossotus was the most abundant species amounting 52,5% of the total number and 31,3% of the biomass of Pleuronectiformes, being widespread all over the study area. Additional comments on the species occurrence and their distribution over the Western Atlantic are given and compared to their relative abundance in the Sepetiba Bay.

  • Caracterization of nest and foraging activity of Trachymyrmex fuscus Emery (Hymenoptera, Formicidae) in Eucalyptus stand

    Araújo, Márcio Silva; Della Lucia, Terezinha M.C.; Mayhé-Nunes, Antônio José

    Abstract in English:

    Seven nests of T. fuscus Emery, 1834 have been studied for their structure. These nests, which opened at the soil surface, had two to four chambers located one above the other. Externally all of these nests presented a heap of brownish-yellow debris that was constituted basically by remains of vegetable material. The total nest population was, on average, 1,048 individuais. The diel pattern of foraging of this species was studied for four consecuti ve months on two nests. This activity occurred predominantly in the night period, and the workers transported, mainly, dry vegetation to the nest.
  • Hawkmoths (Lepidoptera, Sphingidae) in the Tabuleiro Paraibano, northeastern Brazil: abundance, richness and relations to sphingophilous plants

    Darrault, Reisla Oliveira; Schlindwein, Clemens

    Abstract in English:

    Hawkmoths (Sphingidae) are among the major pollinators in tropical communities. Here the first survey of sphingids and related plants in Northeastern Brazil is presented. The sphingids were surveyed from March 1999 through April 2000 at the Reserva Biológica Guaribas, Mamanguape, Paraíba State. On black and mix light traps, 136 hawkmoths from 24 species were captured. Individuais of Erinnyis ello (Linnaeus, 1758), Isognathus menechus (Boisduval, 1875) and Xylophanes tersa (Linnaeus, 1771) represented 58% of the samples. One half of the recorded species show wide distribution in the Neotropics. Three species were registered for more than six months. Most of the species were found only in the dry or wet season. Pollen from 34 plant species were recorded by pollen analysis of sphingid mouth parts. Hancornia speciosa (Apocynaceae) and Guettarda platipoda (Rubiaceae) were the most important food plants. Both are characteristic elements of the Tabuleiro Nordestino and present typically sphingophilous flowers. More than one half of the sphingids presented pollen from only one or two species of plants. By transporting large quantities of pollen of a few species, hawkmoths seem to be the main pollinators of nocturnal flowers in the Tabuleiro Paraibano.

  • Embryology of the swimming crab Arenaeus cribrarius (Lamarck) (Crustacea, Brachyura, Portunidae)

    Pinheiro, Marcelo A.A.; Hattori, Gustavo Yomar

    Abstract in English:

    Ovigerous females of Arenaeus cribrarius were collected at Ubatuba, São Paulo, and maintaining in aquaria under controlled temperature (25±1ºC), salinity (35±1‰) and photoperiod (12:12). A small sample of eggs was collected for each 24h, for morphological description, chromatic changes and biometric analysis throughout the embryonic development. Eight egg stages were photographed and had their small and large diameters measured under a microscope provided with camera lucida. The egg's shape was low elliptical during all the embryogenesis and showed size increase (24.4%) and volume (91.1 %), when the last stage were compared with the first one. According to mean egg diameter and volume, the eggs should be pooled in three different groups (1-3; 4-6; 7-8) corresponding to initial, intermediate and final stages. The attained results were compared with the literature which emphasizing the species of Portunidae's family.

    Abstract in English:

    Emas National Park is a very importam Conservation Unit in the Cerrado Biome. Nevertheless the fauna of this region is still poorly known. In this study, a revised list of the mammal fauna of the Emas National Park with comments about the composition and the number of species surveyed is presented. Eighty six species of mammals were recorded in the Park and neighboring area, including several rare and threatened species, like the bush dog (Speothos venaticus (Lund, 1842)), Marsh deer (Blastocerus dichotomus (Illiger, 1815)) and others. The giant rat (Kunsia tomentosus (Lichtenstein, 1830)) was recorded for the first time in a conservation unit. On the other hand, species usually very common in the Cerrado biome, don't occur in Emas National Park: the brazilian rabbit (Sylvilagus brasiliensis (Linnaeus, 1758)), marmosets (Callithrix spp.), and the punaré (Thrichomys apereoides (Lund, 1841)).

    Almeida, Laura Ribas de; Branco, Joaquim Olinto

    Abstract in English:

    Stellifer stellifer (Bloch, 1790) is one among the most abundant ictiofauna species which are caught by sea-bob-shrimp's artisanal fishery in Armação do Itapocoroy. Aiming to analyze its population structure, a total of 1459 specimens were collected from July/1996 to August/1997. Stellifer stellifer presented lengths varying between 3,7 and 17,7 cm, macroscopic sex differentiation started from 6,0cm, with a higher frequency of females (sex ratio = 1:3,2). The relationship between length and weight was Wt = 0,0073Lt3,1415. First maturation size was determined for females (7,5 cm) and males (8,1 cm). The fishery acts in a similar way on juveniles and adults. Stellifer stellifer presented two spawning seasons, one in spring and another in autumn.
  • Isognomon bicolor (C.B. Adams) (Bivalvia, Isognomonidae): first record to the Brazilian littoral, redescription of the species and comments on the occurrence and distribution of Isognomon in the Brazilian coast

    Domaneschi, Osmar; Martins, Claudio Mantovani

    Abstract in English:

    The bivalve family Isognomonidae is represented in the Western Atlantic by the living genera Crenatula Lamarck, 1804 and Isognomon Solander, 1786. I. alatus (Gmelin, 1791) and I. radiatus (Anton, 1839) are the only Isognomonidae referred to the Brazilian malacofauna. The present work refers to the first record and geographic distribution of I. bicolor along the Brazilian littoral, and presents a re-description of the species based on shell characters, which include those of the prodissoconch. The occurrence of I. alatus and I. radiatus along the Brazilian littoral could not be confirmed, despite the intensive search for these Isognomonidae from Rio Grande do Norte through Rio Grande do Sul.
