ORIGEM E DESTINAÇÃO DA FAUNA SILVESTRE: LEVANTAMENTO DE DADOS NO ESTADO DE SERGIPE

The biodiversity of the Brazilian Northeast region is threatened by human action due to activities such as deforestation and the removal of wild species from their original environment. Thus, this research aims to carry out a descriptive survey about the actions of reception and destination of wild animals performed by the Environment and Renewable Natural Resources Brazilian Institute Environment and Renewable Natural Resources (IBAMA) in the State of Sergipe. For this, data from capture records carried out by IBAMA/SE between 2016 and 2020 were used. The animals that made up this database were classified according to their taxonomic class, being, Birds, Reptiles, or Mammals. The origin of animals that arrived at IBAMA was subdivided as follows: from seizure, rescue, or voluntary delivery. The destination of these animals was classified as: death, release, captivity, or others (when they did not fit into the previous classes). A database was created using Excel® software, and the data were analyzed descriptively. Of the 5247 individuals apprehended over the period studied, most belonged to the bird class (81.9%), followed by reptiles (16.4%) and mammals (1.7%). Seizure was the most common origin of animals received by IBAMA/SE in all evaluated years, in second and third place are voluntary delivery and rescue, respectively. For all taxonomic classes, the main destination of the animals was release, while sending to captivity was the least frequent alternative in all years.A biodiversidade da Região Nordeste Brasileira encontra-se ameaçada pela ação humana devido a atividades como o desmatamento e a retirada de espécies silvestres do seu ambiente de origem. Assim, objetiva-se, com esta pesquisa, realizar um levantamento descritivo acerca das ações de recebimento e destinação dos animais silvestres realizadas pelo Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (IBAMA) no estado de Sergipe. Para isso, foram utilizados os dados provenientes dos registros de captura realizados pelo IBAMA/SE entre os anos de 2016 e 2020. Os animais que compunham esse banco de dados foram classificados conforme sua classe taxonômica, sendo: aves, répteis ou mamíferos. A origem dos animais que chegaram ao IBAMA foi subdividida da seguinte forma: oriundos de apreensão, de resgate ou de entrega voluntária. Já a destinação desses animais foi classificada como: óbito, soltura, cativeiro ou outros (quando não se enquadravam nas classes anteriores). Foi elaborado um banco de dados utilizando o software Excel®, e os dados foram analisados de maneira descritiva. Dos 5.247 indivíduos apreendidos ao longo do período estudado, a maior parte pertencia à classe das aves (81,9%), seguida pela dos répteis (16,4%) e dos mamíferos (1,7%). A apreensão foi a origem mais comum dos animais recebidos pelo IBAMA/SE em todos os anos avaliados; em segundo e terceiro lugar estão a entrega voluntária e o resgate, respectivamente. Para todas as classes taxonômicas, a principal destinação dos animais foi a soltura, enquanto o envio para cativeiros foi a alternativa menos frequente em todos os anos

The role of cinnamon as a modulator of the expression of genes related to antioxidant activity and lipid metabolism of laying quails

Since cinnamon has vitamins and minerals in addition to antioxidants compounds in its chemical composition studies have shown the potential of cinnamon supplementation on some important characteristics in the performance of birds. Thus, this study was conducted under the hypothesis that the inclusion of cinnamon in the laying quail diet could influence the performance of the birds through the expression of genes related to antioxidant activity and lipid metabolism. To test this hypothesis, 144 Japanese quail (Coturnix japonica) with an initial age of 18 weeks and average weight of 133g were distributed in a completely randomized design with two treatments: no cinnamon supplementation (NCS—control group) and with supplementation of 9g/kg of cinnamon powder (CPS). The experiment lasted for 84 days. At the end of the experimental period, six animals from each treatment were euthanized by cervical dislocation, blood was collected and organs weighed. Liver tissue was collected for gene expression and biochemical analyses. We observed a significant effect of cinnamon inclusion on the weight of the pancreas (P = 0.0418), intestine (P = 0.0209) and ovary (P = 0.0389). Lower weights of the pancreas and intestine, and a higher ovary weight was observed in birds receiving the CPS diet. Quails fed with cinnamon supplementation also had better feed conversion per egg mass (2.426 g /g, P = 0.0126), and higher triglyceride (1516.60 mg/dL, P = 0.0207), uric acid (7.40 mg/dL, P = 0.0003) and VLDL (300.40 mg/dL, P = 0.0252) contents. A decreased content of thiobarbituric acid reactive substances (TBARS) and lower catalase activity was observed in the liver of quails from the CPS diet (0.086 nmoles/mg PTN, and 2.304 H2O2/min/mg PTN, respectively). Quails from the CPS group presented significantly greater expression of FAS (fatty acid synthase, 36,03 AU), ACC (Acetyl-CoA Carboxylase, 31.33 AU), APOAI (apolipoprotein A-I, 803,9 AU), ESR2 (estrogen receptor 2, 0.73 AU) SOD (superoxide dismutase, 4,933.9 AU) and GPx7 (glutathione peroxidase 7, 9.756 AU) than quails from the control group. These results allow us to suggest that cinnamon powder supplementation in the diet of laying quails can promote balance in the metabolism and better performance through the modulation of antioxidant activity and the expression of genes related to lipid metabolism

ATLANTIC BIRD TRAITS: a data set of bird morphological traits from the Atlantic forests of South America

Scientists have long been trying to understand why the Neotropical region holds the highest diversity of birds on Earth. Recently, there has been increased interest in morphological variation between and within species, and in how climate, topography, and anthropogenic pressures may explain and affect phenotypic variation. Because morphological data are not always available for many species at the local or regional scale, we are limited in our understanding of intra- and interspecies spatial morphological variation. Here, we present the ATLANTIC BIRD TRAITS, a data set that includes measurements of up to 44 morphological traits in 67,197 bird records from 2,790 populations distributed throughout the Atlantic forests of South America. This data set comprises information, compiled over two centuries (1820–2018), for 711 bird species, which represent 80% of all known bird diversity in the Atlantic Forest. Among the most commonly reported traits are sex (n = 65,717), age (n = 63,852), body mass (n = 58,768), flight molt presence (n = 44,941), molt presence (n = 44,847), body molt presence (n = 44,606), tail length (n = 43,005), reproductive stage (n = 42,588), bill length (n = 37,409), body length (n = 28,394), right wing length (n = 21,950), tarsus length (n = 20,342), and wing length (n = 18,071). The most frequently recorded species are Chiroxiphia caudata (n = 1,837), Turdus albicollis (n = 1,658), Trichothraupis melanops (n = 1,468), Turdus leucomelas (n = 1,436), and Basileuterus culicivorus (n = 1,384). The species recorded in the greatest number of sampling localities are Basileuterus culicivorus (n = 243), Trichothraupis melanops (n = 242), Chiroxiphia caudata (n = 210), Platyrinchus mystaceus (n = 208), and Turdus rufiventris (n = 191). ATLANTIC BIRD TRAITS (ABT) is the most comprehensive data set on measurements of bird morphological traits found in a biodiversity hotspot; it provides data for basic and applied research at multiple scales, from individual to community, and from the local to the macroecological perspectives.
