In mammals, when females are clumped in space, male access to receptive is usually determined by a dominance hierarchy based on fighting ability. polygynandrous primates, as opposed most mammalian species, the strength of relationship between social status and reproductive success varies greatly. It has been proposed that degree which paternity rank decreases with increasing female synchrony. The priority-of-access model (PoA) predicts synchrony rank. To date, tests PoA using data involved...
Abstract In group living animals, especially among primates, there is consistent evidence that high‐ranking males gain a higher reproductive output than low‐ranking males. Primate studies have shown male coalitions and sociality can impact fitness; however, it remains unclear whether could potentially increase their fitness by preferentially supporting socializing with females. Here we investigate patterns of interventions the effect on in rhesus macaques ( Macaca mulatta ) particular focus...
Abstract Theory and a growing body of empirical evidence suggest that higher ranking males experience reproductive advantages in group‐living mammals. White‐faced capuchins ( Cebus capucinus ) exhibit an interesting social system for investigating the relationship between dominance success (RS) because they live multimale multifemale groups, which alpha can have extraordinarily long tenures (i.e. coreside with daughters age). Genetic paternity was determined from fecal samples 120 infants...
When close relatives mate, offspring are expected to suffer fitness consequences due inbreeding depression. Inbreeding has previously been quantified in two ways: using a sufficiently large panel of markers or deep and complete pedigrees over several generations. However, the application both approaches is still limited by challenge compiling such data for species with long generation times, as primates. Here, we assess rhesus macaques living on Cayo Santiago (Puerto Rico), population...
Genetic analyses based on noninvasively collected samples have become an important tool for evolutionary biology and conservation. Crested macaques (Macaca nigra), endemic to Sulawesi, Indonesia, are our understanding of primate evolution as Sulawesi represent exceptional example adaptive radiation. also Critically Endangered. However, date we know very little about their genetics. The aim study was find validate microsatellite markers useful evolutionary, conservation, other genetic studies...
We studied the context of brood reduction through infanticide by communally breeding Guira Cuckoos (Guira guira) in central Brazil. During seven reproductive seasons, we monitored 142 nests from egg laying until fledging. Almost all (97%) lost eggs ejection, and chick deaths occurred 72% with hatchlings. There was evidence for 38% that exhibited some mortality. compared mortality early part season later part, when insect abundance declines, but found no significant differences. Less than...
Seventeen polymorphic microsatellite loci were identified for white-faced capuchin monkeys from an enriched genomic library in addition to one locus found through cross-species comparisons. In a sample of 187 wild individuals, these exhibited average five alleles and observed heterozygosity 0.62. The combined probability exclusion random individual parentage was 0.99. These screened 23 other New World seven variable per species, suggesting that could be use studies Neotropical primates.
ABSTRACT Hyperostotic bones occur in several families of marine teleosts, however there are few reports on its development fish from Brazilian waters. The present study identified the occurrence hyperostosis specimens Leatherjacket Oligoplites saurus, an important commercial species, using radiographic images. Biometric measurements four were performed and affected detected different levels regions skeleton: Supraoccipital, Pterygiophores, Cleithrum, Hemal Spines Neural Spines. Bones with...
Guira Cuckoos (Guira guira) are cooperative breeders with joint nests, where several breeding and nonbreeding males females remain in a cohesive unit through repeated attempts within single territory. We used nine microsatellite markers to analyze parentage relatedness population of central Brazil, comprising 225 progeny from 51 attempts. The presented variety mating patterns, polygynandry monogamy being the most common. found low levels extragroup fertilization, cobreeding groups shared...
