Dispersal and in Situ Speciation as Contributors to Plant Diversity in the Chocó Region: Insights From Inga Mill. (Leguminosae)NARA Subscribed
Aim To investigate the historical processes underlying the assembly of the flora of the Chocó region, with a focus on the relative contributions of dispersal and in situ speciation. Using Inga (Leguminosae) as a model lineage, we evaluate the origin and diversification of species present in the Chocó. Location The Chocó region, a lowland rainforest located across southern Panama, the Pacific coast of Colombia, the Magdalena hu...
Purpose Patch-clamping is a foundational technique in electrophysiology that requires substantial training due to its complexity and resource-intensive nature. This study evaluates the effectiveness of an interactive patch-clamping simulation in improving accessibility, skill acquisition, and educational outcomes compared to traditional training methods. Methods A virtual simulation replicating key aspects of patch-clamping wa...
Terrigenous inputs link nutrient dynamics to microbial communities in a tropical lagoonNARA Subscribed
Nutrient availability drives community structure and ecosystem processes, especially in tropical lagoons that are typically oligotrophic but often receive allochthonous inputs from land. Terrestrially derived nutrients are introduced to tropical lagoons by surface runoff and submarine groundwater discharge, which are influenced by seasonal precipitation. However, terrigenous inputs presumably diminish along the onshore–offshor...
Seasonal occurrence and condition of leopard seals at an extralimital Sub-Antarctic IslandNARA Subscribed
Leopard seals ( Hydrurga leptonyx ) occur mainly south of the Antarctic Polar Front, but immatures, in particular, seasonally move beyond this range during the austral winter and spring, typically under increased sea ice conditions. Extralimital occurrences of leopard seals can be observed at several sub-Antarctic islands where they haul out to rest. We present new records of leopard seal sightings at Marion Island, southern I...
Fish and invertebrate communities show greater day–night partitioning on tropical than temperate reefsNARA Subscribed
Diel partitioning of animals within ecological communities is widely acknowledged, yet rarely quantified. Investigation of most ecological patterns and processes involves convenient daylight sampling, with little consideration of the contributions of nocturnal taxa, particularly in marine environments. Here we assess diel partitioning of reef faunal assemblages at a continental scale utilizing paired day and night visual censu...
Industrialized environments, despite benefits such as higher levels of formal education and lower rates of infections, can also have pernicious impacts upon brain atrophy. Partly for this reason, comparing age-related brain volume trajectories between industrialized and non-industrialized populations can help to suggest lifestyle correlates of brain health. The Tsimane, indigenous to the Bolivian Amazon, derive their subsisten...
Toward sustainable harvest strategies for marine fisheries that include recreational fishingNARA Subscribed
Recreational fishing (RF) is a large yet undervalued component of fisheries globally. While progress has been made in monitoring, assessing, and managing the sector in isolation, integration of RF into the management of multi‐sector fisheries has been limited, particularly relative to the commercial sector. This marginalises recreational fishers and reduces the likelihood of achieving the sector's objectives and, more broadly,...
Successful fisheries management systems tend to be underpinned by harvest strategies, specifying formally agreed data collection systems, assessment approaches and management measures used to regulate fishing pressure. While harvest strategies can be effective even in data‐ and capacity‐limited (DCL) situations, their development remains challenging in such contexts. We present a process and decision‐support tool, FishPath, to...

The global impacts of climate change are evident in every marine ecosystem. On coral reefs, mass coral bleaching and mortality have emerged as ubiquitous responses to ocean warming, yet one of the greatest challenges of this epiphenomenon is linking information across scientific disciplines and spatial and temporal scales. Here we review some of the seminal and recent coral‐bleaching discoveries from an ecological, physiologic...
