Efforts to reverse the decline of endangered golden lion tamarin monkeys have been relatively successful because Brazilian organization dedicated species' conservation (Associação Mico-Leão-Dourado, AMLD) relies on science-based computer modeling determine number tamarins necessary achieve demographic and genetic goals, a process strategic planning those goals. Accurate estimates numbers in forest fragments are essential evaluate progress achieving goals adapt strategies as necessary. In...
Abstract Callitrichidae is a unique primate family not only in terms of the large number food transfers to infants but also for prevalence that are initiated by adults. It has been hypothesized that, as well provisioning infants, callitrichid might function teach receiver what types eat. If teaching function, we would expect successful be more likely with novel juveniles. We juveniles learn about foods from those transfers. introduced different (some familiar, some novel) wild groups golden...
ABSTRACT Radiographic pelvimetry is the measurement of pelvic diameters by radiographs. The results allow us to determine pelvimetric pattern a species, generating data for prophylactic methods against parturition complications and providing pelvis' anatomical classification. There lack such on wild animals. Callithrix penicillata C. jacchus are two marmoset species introduced in Southeast Brazil, mainly anthropic action, successfully adapted hybridized. This study aimed perform measurements...
Visceral uric gout is a metabolic disorder characterized by the accumulation of urate crystals on serous surfaces coelomic cavity and in kidneys. In present study, we describe case visceral an adult black-fronted piping guan (Aburria jacutinga) under human care. Macroscopic findings showed mesentery, pericardium, liver, The kidneys were enlarged, vessels right kidney congested. Microscopically, observed presence fine with appearance "needles". lesions found are compatible those previously...
ABSTRACT New World porcupines (Erethizontidae) exhibit behaviors and possess integumentary structures, including the quills, that are used for self‐defense. The North American porcupine ( Erethizon dorsatum ) has been well studied regarding these features; however, information is lacking South Coendou species. We describe defensive behavior morphology of spinosus to understand strategies this species compare with those reported other assessed related warning, defense, escape eight...
One of the negative effects linear infrastructures is formation barriers to movements for arboreal wildlife resulting in reduction connectivity between populations and thus increasing risk extinction. most widely used ways mitigate these barrier canopy bridges. There a lack knowledge about how behavioral differences species may affect efficacy The purpose this study was evaluate hypothesis that Leontopithecus rosalia (an endangered endemic species) Callithrix spp. hybrids (introduced...
We provide here a current overview of marmoset (Callithrix) evolution, hybridization, species biology, basic/biomedical research, and conservation initiatives. Composed two subgroups, the aurita group (C. C. flaviceps) jacchus geoffroyi, jacchus, kuhlii penicillata), this relatively young primate radiation is endemic to Brazilian Cerrado, Caatinga, Atlantic Forest biomes. Significant impacts on Callithrix within these biomes resulting from anthropogenic activity include: (1) population...
O objetivo neste trabalho foi avaliar a aplicabilidade, para búfalos (Bubalus bubalis), de testes avaliação temperamento, utilizados bovinos. Foram avaliados os docilidade, teste reação objetos novos, tronco e isolamento social em 12 bezerros suas mães, separadamente. Tanto como mães responderam todos com vários comportamentos. Para as que promoveram maior número comportamentos foram o novos. Houve diferenças individuais (coeficiente variação 32-51%) nos resultados tanto nas mães. Os...
Population control techniques, either permanent or reversible, are important tools for the management of wildlife in captive and natural environments. Among these, surgical sterilization provides a solution to unwanted reproduction. Surgical techniques can differ their invasiveness subsequent effect on behavior physiology. For social animals, that preserve gonads, such as vasectomy males ligation uterine tubes females, may be preferred because they maintain physiology influences behavior....
ABSTRACT We report a viral metagenomic analysis of fecal samples from Bradypus crinitus , recently described sloth species that occurs in the Atlantic Forest Espírito Santo and Rio de Janeiro states, Southeast Brazil. Through Illumina sequencing, we generated total 2,065,344 raw reads, which 945,386 reads (45.77%) passed quality size filter. The highest proportion them was assigned to Eukarya, followed by Bacteria only small Virus. However, identified 24 families using distinct taxonomic...
ABSTRACT The porcupine ( Coendou spinosus ) is a rodent species widely distributed in the Brazilian Atlantic forest. Like other species, porcupines can be potential reservoirs of zoonotic agents. However, little known about viral diversity these animals. Therefore, objective present study was to evaluate, through massive sequencing, virome feces seven adult healthy free-living living forest fragments from Silva Jardim, State Rio de Janeiro, Brazil. A total 41 families were classified, which...
A Aburria jacutinga é uma ave de grande porte residente em um dos biomas mais ameaçados do Brasil, a Mata Atlântica, e vem sofrendo cada vez com ações antrópicas como caça o desmatamento.Portanto, para impedir extinção espécies ameaçadas, especial jacutinga, existem programas conservação reintrodução na natureza.Este estudo tem objetivo divulgar primeira etapa avaliação monitoramento potencial predador da jacutinga.Foram realizadas análises quantitativas qualitativas imagens obtidas cinco...
