ABSTRACT The northeast area of São Paulo state has been intensively deforested, resulting in a highly fragmented landscape composed few large patches and several small natural vegetation surrounded by sugarcane, eucalyptus, citrus plantations. In this scenario, we investigated the puma ( Puma concolor ) population size, sex ratio, relatedness two last, largest, refuges using noninvasive method during 2004–2008. By collecting individualizing fecal samples microsatellites, identified 17...
Abstract Mortality from collision with vehicles is the most visible impact of road traffic on wildlife. due to roads (hereafter road‐kill) can affect dynamic populations many species and can, therefore, increase risk local decline or extinction. This especially true in Brazil, where plans for network upgrading expansion overlaps biodiversity hotspot areas, which are high importance global conservation. Researchers, conservationists planners face challenge define a national strategy...
Allozyme analyses have suggested that Neotropical orchid bee (Euglossini) pollinators are vulnerable because of putative high frequencies diploid males, a result loss sex allele diversity in small hymenopteran populations with single locus complementary determination. Our analysis 1010 males from 27 species euglossine bees sampled across the Neotropics at 2–11 polymorphic microsatellite loci revealed only five an overall frequency 0.005 (95% CIs 0.002–0.010); errors through genetic...
We assessed the polymorphism of 10 microsatellites in Brazilian Nellore cattle (Bos indicus) using a commercial multiplex system. Allele frequencies, information content, heterozygosity and exclusion probability were calculated. frequencies revealed that sample analyzed markers not equally polymorphic. The probabilities content some loci lower than Bos taurus breeds. When all considered combined was 0.9989. This analysis can contribute toward pedigree information, adequate genetic...
Abstract The genetics and ecology of pumas are well documented in North America but there is a lack studies South America, especially Brazil. By means noninvasive method, faecal DNA analysis, we estimated puma abundance two protected areas embedded human-disturbed landscape the north-east São Paulo state, south-east In 8 months mark–recapture faeces sampling, 15 individual were identified using seven microsatellite loci. with Jolly–Seber open population model was 23.81 ± SE 6.22. This first...
Abstract The Neotropical Euglossini (Hymenoptera: Apidae) are important pollinators of many flowering plants, particularly orchids. Lack highly polymorphic genetic markers for euglossine species has limited the study their social organization and inbreeding. We therefore developed microsatellite two species, Eulaema nigrita (11 loci) Euglossa cordata (nine loci), most which were in source a range related bees.
The main goal of this dataset is a compilation geo-referenced road-kill data from published and unpublished road surveys. encompasses records 45 personal communications 26 studies in peer-reviewed journals, theses, reports. comprises 21,512 records, 83% which are identified to the species level (n = 450 species). This can be used identify taxa seem vulnerable traffic, analyze temporal spatial patterns at local, regional, national scales also understand effects on population persistence....
Habitat fragmentation can promote patches of small and isolated populations, gene flow disruption between those reduction local total genetic variation. As a consequence, these populations may go extinct in the long-term. The ocelot (Leopardus pardalis), originally distributed from Texas to southern Brazil northern Argentina, has been impacted by habitat throughout much its range. To test whether already induced differentiation an area where this process documented for larger felid...
A new species of freshwater crab, Fredius ibiapaba, is described and illustrated from a mid-altitude forested patch in Ipú (Ibiapaba plateau, Ceará, northeastern Brazil), between 635 to 782 m. The can be separated its congeners by the morphology first gonopod: proximal half remarkably swollen, sloping abruptly downwards distally nearly right-angular shoulder; mesial lobe much smaller than cephalic spine; moderately developed; auxiliary lip, delimiting field apical spines, protruded all way...
Canchim, a synthetic breed of cattle derived from the Charolais and Zebu group has been used in beef-cattle industry Brazil as an alternative for intensifying production. One main concerns with this is its poor fat deposition consequently, there effort to increase performance trait. The thyroglobulin gene located QTL region deposition, reports describe influence polymorphism 5´ leader sequence that on marbling subcutaneous thickness. This study analyzed association gene, well two flanking...

Background: Closed breeding populations are usefull to conduct basic and applied research. The Wye Angus herd is one of them. It was founded using only a few animals. pedigree the descendants original can be completely described by historical records resulting from strong selection. genetics has influenced that Aberdeen Angus, Red Brangus cattle worldwide. Objective: To evaluate parameters genetic trends associated with reproduction traits between years 1937 2012. Methods: We used...
