Genetic evidence of female philopatry in a socially polyandrous shorebird.

Journal Article Evolution; international journal of organic evolution · March 2025 Sex-biased dispersal plays a key role in shaping population dynamics and genetic structure. Two main hypotheses have been proposed for how territoriality and mating competition impact sex-biased dispersal. Female-biased dispersal is expected in monogamous ... Full text Cite

Impact of Quaternary Amazonian river dynamics on the diversification of uakari monkeys (genus Cacajao)

Journal Article Journal of Biogeography · August 1, 2024 Aim: The central and western Amazonia underwent several landscape changes during the Quaternary. Whereas the Riverine Barrier Hypothesis is traditionally used to explain the influence of rivers on speciation, processes such as river rearrangements have bee ... Full text Cite

Whole genome assessment of a declining game bird reveals cryptic genetic structure and insights for population management.

Journal Article Molecular ecology · October 2023 Population genomics applied to game species conservation can help delineate management units, ensure appropriate harvest levels and identify populations needing genetic rescue to safeguard their adaptive potential. The ruffed grouse (Bonasa umbellus) is ra ... Full text Cite

Late Pleistocene landscape changes and habitat specialization as promoters of population genomic divergence in Amazonian floodplain birds.

Journal Article Molecular ecology · January 2023 Although vicariant processes are expected to leave similar genomic signatures among codistributed taxa, ecological traits such as habitat and stratum can influence genetic divergence within species. Here, we combined landscape history and habitat specializ ... Full text Cite

Genomic differentiation with gene flow in a widespread Amazonian floodplain‐specialist bird species

Journal Article Journal of Biogeography. · September 2022 AIM: Ecological, climatic and palaeogeographical processes drive biological diversification. However, the evolutionary outcomes of those mechanisms are complex and difficult to discriminate. Here, we test how alternative drivers affected connectivity along ... Full text Cite

Habitat association constrains population history in two sympatric ovenbirds along Amazonian floodplains

Journal Article Journal of Biogeography. · September 2022 AIM: Amazonian floodplains include distinct types of seasonally flooded habitats, determined by the flooding regime and sedimentation dynamics. Some bird species prefer specific habitat types within the floodplains. To investigate whether distinct habitats ... Full text Cite

Genetic monitoring of the Critically Endangered Araripe Manakin reveals low diversity and declining effective population size

Journal Article Ornithological Applications · May 5, 2022 Genetic information is still underestimated in conservation policies, seldom being monitored or included in management strategies. Monitoring changes in genetic diversity over time in endangered species is useful to anticipate possible risks associated wit ... Full text Cite

Historical climate change as driver of populational range expansion and differentiation in a rare and partially migratory Neotropical bird

Journal Article Journal of Ornithology · April 1, 2022 Populations peripheral to a species’ distribution are more susceptible to new selective pressures, changes, differentiation, and extinction. The Sooty Swift Cypseloides fumigatus (Apodidae) is a rare bird found mainly in central and southeastern South Amer ... Full text Cite

Peripheral isolation and demographic stability are reflected in the genetic diversity of the populations of the Helmeted Manakin: a bird endemic to the gallery forests.

Journal Article Anais da Academia Brasileira de Ciencias · January 2022 The Cerrado encompasses a complex network of hydrographic basins, which is responsible for the formation and maintenance of the riparian and gallery forests. Alterations in the vegetation resulting from the paleoclimatic changes that occurred during the Pl ... Full text Cite

Characterization of the genetic diversity and population structure of the manakin genus Antilophia through the development and analysis of microsatellite markers

Journal Article Journal of Ornithology · July 1, 2019 The two species of the genus Antilophia, Antilophia bokermanni and Antilophia galeata, are found in environments that are undergoing extensive modification, which may be provoking the loss of their genetic diversity. Nine polymorphic microsatellite loci we ... Full text Cite

Recent chapters of Neotropical history overlooked in phylogeography: Shallow divergence explains phenotype and genotype uncoupling inAntilophiamanakins

Journal Article Molecular Ecology · October 2018 AbstractEstablishing links between phenotypic and genotypic variation is a central goal of evolutionary biology, as they might provide important insights into evolutionary processes shaping genetic and species diversity in ... Full text Cite

Molecular data and distribution dynamics indicate a recent and incomplete separation of manakins species of the genus Antilophia (Aves: Pipridae) in response to Holocene climate change

Journal Article Journal of Avian Biology · August 2017 To determine a hypothetical scenario that accounts for the diversification of the two species of the genus Antilophia , we conducted multilocus molecular compar ... Full text Cite
