The Capture-Seizure of Wild Animals in Brazil: Relationships with Rainfall Variability

Abstract

This study intends to outline a profile of the capture-seizure of wild animals in Brazil, in the five geographic regions (North, Northeast, Midwest, Southeast and South). The objective was to identify and investigate its variability with its regionais differences and, if possible, relate its climatic characteristics, with emphasis on the variation of rainfall in the regions. Data used in study were of annual captures of wild animals (birds, reptiles, amphibians and others) seized by various institutions in the country, responsible for the inspection and control of this illegal activity, collected by the National Network Against the Trafficking of Wild Animals (RENCTAS) during the period. 1992-2000. For precipitation, monthly data was used, to make inferences of relationships with the capture and seizure data of wild animals, collected from the National Precipitation Climatology Center (GPCC) project of the National Center for Environment Prediction - National Oceanic Atmospheric Admistration (NCEP-NOAA). For an area between 80° W-10° E and 80° S-5° N for the period 1950-2016. The basic methodology used in the study will be an analysis of parameters of descriptive statistics as measures of central tendency and dispersion to identify the regional differences in catches of these wild animals, in addition to the use of linear correlation in order to relate this quantity of catches with the distribution precipitation in Brazilian territory. It is hoped with the results to outline a profile of this illegal activity in Brazil and its regionais differences and its relations with pluviometric variability, which the same can provide information to the competent institutions so that strategies to combat this illegal practice can be better implemented.
