Challenges, pitfalls, and potential solutions in assessing status and trends of Spheniscus penguinsOA Marine
Reliable, up-to-date assessments of population status and trends are essential for effective conservation. For the four Spheniscus penguin species, these are often undermined by methodological and logistical constraints due to their unique breeding ecology (e.g., burrow nesting and asynchronous breeding). As a result, no single survey method is universally applicable across the genus. Moreover, uneven sampling effort, inconsis...
Navigating Future Waters: The Resilience of the Atlantic Bluefin Tuna Under Climate ChangeNARA Subscribed
Atlantic bluefin tuna (ABFT) is an ecologically and economically valuable species. As global warming drives marine species toward cooler or deeper waters, ABFT distributions are expected to shift, potentially disrupting predator–prey dynamics and fisheries interactions. This study models future habitat suitability for ABFT, its primary prey (as a proxy for food availability), and the drifting longline fishery that targets adul...

Hydrological seasonality is a major driver of ecosystem metabolism in tropical nonwadeable riversNARA Subscribed
Studies of annual patterns of ecosystem metabolism in rivers have primarily been conducted in temperate ecosystems, and little is known about metabolic regimes of tropical rivers. We estimated ecosystem metabolism in four nonwadeable rivers in southern México that varied in size and the extent of human disturbance. The smaller rivers with limited human disturbance showed reduced gross primary production (GPP; 1.0 and 1.7 g O 2...
Islands Promote Diversification of the Silvereye Species Complex: A Phylogenomic Analysis of a Great SpeciatorNARA Subscribed
Geographic isolation plays a pivotal role in speciation by restricting gene flow between populations through distance or physical barriers. However, the speciation process is complex, influenced by the interplay between dispersal ability and geographic isolation, as seen in “great speciators” – bird species that simultaneously have broad island distributions but high levels of subspecific diversity. Comparing genomic populatio...
Biological activities of hydroxyanthracene derivatives (HADs) from Aloe species and their potential usesNARA Subscribed
Hydroxyanthracene derivatives (HADs) are a class of naturally occurring organic compounds known for their diverse biological activities and applications. Due to their pharmacological versatility, hydroxyanthracene derivatives represent a major area of interest in natural products research and drug development. They are found in a wide variety of organisms including bacteria, fungi, plants and some animals. One of the most impo...
Driving variables to explain soil organic carbon dynamics: páramo highlands of the Ecuadorian Real mountain rangeNARA Subscribed
Purpose Large soil organic carbon (SOC) reserves and a high soil capacity for SOC storage within an ecosystem contribute to mitigating the release of carbon into the atmosphere. Developing new spatially-explicit SOC estimation methods at local and micro-watershed scales is essential for gaining landscape understanding of SOC variability. Methods This study provides new insights into the spatial variability of SOC in the Andean...
