Ecosphere, Volume 17, Issue 10, October 2026.Abstract Predators regulate prey populations across ecosystems, driving heterogeneity in prey distribution through both direct consumption and indirect “fear” effects. Such effects generally demonstrate a positive relationship with predator density and length of exposure to predation. Juvenile white sharks (Carcharodon carcharias; JWS) are a generalist

Biological assays with special reference to biological standards [PDF]
Journal of Hygiene, 1950 A paper on biological assays and biological standards might be expected to start with a definition. What is a biological assay and what is a biological standard? However, I shall for the moment make the somewhat doubtful assumption that we all know the answer to those questions but shall return to them later, making a start meanwhile by discussing some

Remote Sensing in Ecology and Conservation, Volume 12, Issue 5, Page 832-840, October 2026.Seabed landers, when equipped with a range of biotic and abiotic sensors, offer a non‐invasive and cost‐effective solution for ecosystem‐scale monitoring of Essential Biodiversity Variables (EBVs) and Essential Ocean Variables (EOVs) in dynamic shallow seas.

Biological information specialists for biological informatics.
Journal of biomedical discovery and collaboration, 2007 Data management and integration are complicated and ongoing problems that will require commitment of resources and expertise from the various biological science communities. Primary components of successful cross-scale integration are smooth information management and migration from one context to another.

Flexible unimodal density estimation in hidden Markov models
Methods in Ecology and Evolution, Volume 17, Issue 10, Page 2994-3005, October 2026.Abstract Hidden Markov models (HMMs) are powerful tools for modelling time‐series data with underlying state structure. However, selecting appropriate parametric forms for the state‐dependent distributions is often challenging and can lead to model misspecification.

Ibis, Volume 168, Issue 4, Page 1649-1663, October 2026.Translocations are often used in the conservation of large raptors, including Old World vultures. Different release methods are usually assessed by comparing the movement patterns and survival of released individuals. However, these approaches fail to capture the gregarious behaviour of many vulture species.

Molecular Ecology, Volume 35, Issue 19, October 2026.ABSTRACT Conservation of biodiversity is a global priority as human‐driven pressures continue to intensify and alter ecosystems worldwide. Marine mammals are vulnerable species, facing numerous escalating anthropogenic threats. Here, we evaluate how, as omics technologies become more accessible and affordable, established and emerging tools are ...

Satellite telemetry suggests significant regional variation in post-fledging survival of Adélie penguinsSatellite telemetry suggests significant regional variation in post-fledging survival of Adélie penguins [PDF]
Royal Society Open SciencePost-fledging periods represent one of the most vulnerable stages for juvenile seabirds. Adélie penguins Pygoscelis adeliae must quickly develop foraging skills while minimizing predation risk immediately after fledging.
