A Antártica é uma peça-chave na dinâmica climática no planeta. Seu clima frio característico responsável pela manutenção da temperatura, modulação de fenômenos climáticos globais, sustentação ecossistemas e biodiversidade dependente do gelo. Da mesma forma, a região impactada maneira expressiva pelas mudanças climáticas globais. Ao longo das últimas décadas, o Programa Antártico Brasileiro vem empregando esforços estudo região, com diversos módulos instalações empregados captação dados...
To evaluate the habitat loss due to climatic changes and their effect on Callithrix diversity in next few decades, present study reported resilience of Atlantic Rainforest primate genus under perspective forecasted South America quick-pace changing environmental policies Brazil.The used present-day distribution marmosets several bioclimatic layers model project suitability for all species recent decades.The presented results are far from being optimistic.Almost except C. jacchus will...
At the beginning of 20th century, intense whaling activity took place in South Shetland Islands, which is represented today form ruins and numerous whale bones scattered along several Antarctic beaches. Despite being exposed to a harsh environment throughout last decades, present manuscript tried answer if these bone remains still have viable DNA allow species' identification using molecular methods. Several individuals were collected from shores Keller Peninsula, Admiralty Bay, Antarctica,...
Extremophile organisms have been largely studied in Astrobiology. Among them, two antarctic plants emerge as good candidates to become colonizers of other celestial bodies, such Mars and the Moon. The present research aimed evaluate survival growing capacity Sanionia uncinata Colobanthus quitensis on Martian (MGS-1) Lunar (LMS-1) regolith simulants, under terrestrial conditions. responses both species simulators original sampling site Antarctic soil were observed during 15 days, laboratory...
The exploration of extraterrestrial environments has become a focal point scientific inquiry, driven by advancements in technology and growing interest the potential for life beyond Earth. This study investigates adaptability Antarctic nematodes, known thriving extreme cold isolation, to simulated Martian (MGS-1) Lunar (LMS-1) soils. experiment revealed differential responses nematode survivability two simulants, with soil demonstrating better compared soil. Our provides valuable insights...
Studies with cetaceans using degraded samples have faced challenges for molecular identification based on the barcoding methodology and other sequencing techniques due to fragmented nature of genetic material found these samples.In this article, we evaluated use insertion-deletion regions cetaceans.The presented allows species numeric profiles related chosen InDel regions, a forensic gold standard commonly used that cannot be sequenced easily.We carried out an in silico analysis previously...

The polar regions are home to a great biodiversity of vertebrates that highly impacted by climate change.As extreme and pristine ecosystems, the use environmental DNA (eDNA) presents itself as noninvasive tool for monitoring vertebrates' species, essential their preservation.In this article, we review currently published research on vertebrate eDNA in Arctic, well compare it with similar already-published article Antarctica.Our results show how Artic region is represented several studies...
