How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Gelatinous zooplankton (GZP; including salps and cnidarians) are reputed to be climate change winners. This so-called “jellification” is affecting several marine ecosystems worldwide, including the Southern Ocean (SO) in particular which has undergone a significant shift from a krill-based to a salp-based ecosystem over the last decades. A better k...
Rapid regional warming causing glacial retreat and melting of ice caps in Antarctica leads benthic filter-feeders to be exposed to periods of food shortage and high respiratory impairment as a consequence of seasonal sediment discharge in the West Antarctic Peninsula coastal areas. The molecular physiological response and its fine-tuning allow spec...
La Antártida y su océano han estado aislados efectivamente del resto de océanos y continentes del planeta por más de 20 millones de años. El Océano Austral es uno de los ecosistemas marinos más diversos y ricos, compuesto por un ensamble biótico adaptado a condiciones sumamente estables y extremas de vida. Sin embargo, en los últimos 60 años la Pen...
The Southern Ocean is one of the most isolated marine ecosystems, characterized by high levels of endemism, diversity, and biomass. Ascidians are among the dominant groups in Antarctic benthic assemblages; thus, recording the evolutionary patterns of this group is crucial to improve our current understanding of the assembly of this polar ocean. We...
Faecal glucocorticoid measurement is a potentially important tool for improving wildlife conservation, but its use is still limited by methodological issues including the need to avoid modifications of steroids by faecal microorganisms during storage. The freezing of faeces is recommended as a means of avoiding such alterations, but this is costly...
Measuring fecal glucocorticoids have potential to improve wildlife conservation, but there are methodological concerns. Collected feces require storage and transport methods to avoid steroid degradation by fecal microorganisms. Freezing is usually recommended; however, it is a costly method under non-controlled environmental conditions. This study...
