Significance Penguins have long been of interest to scientists and the general public, but their evolutionary history remains unresolved. Using genomes, we investigated drivers penguin diversification. We found that crown-group penguins diverged in early Miocene Australia/New Zealand identified Aptenodytes (emperor king penguins) as sister group all other extant penguins. first occupied temperate environments then radiated cold Antarctic waters. The Circumpolar Current’s (ACC)...
Abstract Genomic adaptation and introgression can occur during the speciation process, enabling species to diverge in their frequencies of adaptive alleles or acquire new that may promote environmental changes. There is limited information on organisms from extreme environments responses climate change. To address these questions, we focused three southern skua species, selected for widespread distribution across Southern Hemisphere complex history events. Our genomic data reveal skuas...
Abstract Although mitochondrial DNA has been widely used in phylogeography, evidence emerged that factors such as climate, food availability, and environmental pressures produce high levels of stress can exert a strong influence on genomes, to the point promoting persistence certain genotypes order compensate for metabolic requirements local environment. As recently discovered, gentoo penguins ( Pygoscelis papua ) comprise four highly divergent lineages across their distribution spanning...
Since at least the middle-Miocene, Antarctic Polar Front (APF) and Subtropical (STF) appear to have been main drivers of diversification marine biota in Southern Ocean. However, highly migratory birds mammals challenge this paradigm importance oceanographic barriers. Eudyptes penguins range from Peninsula subantarctic islands some southernmost subtropical islands. Because recent diversification, number species remains uncertain. Here we analyze two mtDNA (HVRI, COI) nuclear (ODC, AK1)...
Over evolutionary time, pathogen challenge shapes the immune phenotype of host to better respond an incipient threat. The extent and direction this selection pressure depend on local composition, which is in turn determined by biotic abiotic features environment. However, little known about adaptation threats wild animals. Gentoo penguin (Pygoscelis papua) a species complex that lends itself study because its circumpolar distribution over large latitudinal range, with or no admixture between...
Abstract Aim The conservation of biodiversity is hampered by data deficiencies, with many new species and subspecies awaiting description or reclassification. Population genomics ecological niche modelling offer complementary tools for uncovering functional units phylogenetic diversity. We hypothesize that phylogenetically delineated lineages gentoo penguins ( Pygoscelis papua ) distributed across Antarctica sub‐Antarctic Islands are subject to spatially explicit conditions have limited gene...
The polar regions provide valuable insights into the functioning of Earth’s regulating systems. Conducting field research in such harsh and remote environments requires strong international cooperation, extended planning horizons, sizable budgets long-term investment. Consequently, is particularly vulnerable to societal economic pressures during periods austerity. global financial crisis 2008, ensuing decade slowdown, have already adversely affected research, current COVID-19 pandemic has...
Context Biological invasions have caused dramatic changes in native biodiversity and ecosystem function. Studies of genetic variation evolutionary are useful for understanding population dynamics during biological invasions, shed light on management, prevention restoration strategies. Aims This study aimed to investigate the structure variability American mink (Neovison vison), an invasive species southern South America, introduced fur farming 1930s. Methods Samples from 153 were obtained 12...
The increased availability of quality genomic data has greatly improved the scope and resolution our understanding recent evolutionary history wild species adapted to extreme environments their susceptibility anthropogenic impacts. guanaco (Lama guanicoe), largest ungulate in South America, is a good example. well wide range habitats, including Sechura Desert, high Andes Mountains north, temperatures conditions Navarino Island south. Guanacos also have long overexploitation by humans. To...
Microsatellites are valuable molecular markers for evolutionary and ecological studies. Next generation sequencing is responsible the increasing number of microsatellites non-model species. Penguins Pygoscelis genus comprised three species: Adélie (P. adeliae), Chinstrap antarcticus) Gentoo penguin papua), all distributed around Antarctica sub-Antarctic. The species have been affected differently by climate change, use microsatellite will be crucial to monitor population dynamics. We...
Octodon (Octodontidae) is an endemic genus of rodents that typical southwestern South America and represented by 4 species. pacificus, commonly referred to as the Mocha Island degu, was initially described from specimens collected in 1959 at Island, a small coastal island located along central coast Chile. Fifty-seven years after its original collection, we report discovery female O. pacificus carcass, identified morphological characteristics specific locality. In addition, based on...
Abstract The relative importance of genetic drift and local adaptation in facilitating speciation remains unclear. This is particularly true for seabirds, who can disperse over large geographic distances, providing opportunities intermittent gene flow among distant colonies that span the temperature salinity gradients oceans. Here, we delve into genomic basis banded penguins, Galápagos (Spheniscus mendiculus), Humboldt (S. humboldti), Magellanic magellanicus) African penguins demersus), by...
Uno de los principales problemas en la acuicultura es el estrés al que se pueden ver sometidas las especies cultivo, por esto desarrollo técnicas alternativas para minimizar son gran ayuda. Tegula atra un gastrópodo habita submareal e intermareal, con importancia económica local y debido a su conducta herbívora, planteó hipótesis esta especie puede ser útil control del crecimiento macroalgas estanques, mediante cultivo mixto. En presente estudio, midió porcentaje ramoneo, respiratoria...
