Spiders in the mosaic: How habitat heterogeneity and structure drive local spider diversity in a Mediterranean forest

open access: yesEcological Entomology, EarlyView.
We assessed alpha‐ and beta‐diversity patterns of spiders across different forests and across vegetation layers (ground, shrub, low canopy) at local spatial scales across various Mediterranean forest types. Across forests, alpha‐diversity increased with habitat heterogeneity, which also drove beta‐diversity patterns across plots .

Leadership Under Risk: Male Vervet Monkeys' (Chlorocebus pygerythrus) Roles in Group Progression Across Potentially High‐Risk Terrain

open access: yesEthology, EarlyView.
Male vervet monkeys were more likely to lead group progressions than females or juveniles, especially during potentially riskier crossing situations, i.e., rivers. Dominant males who had not yet sired offspring were the most likely to lead progressions.

Sex‐Specific Atlantic Salmon Upstream Passage and Fallback at a Natural Cascade After Dam Removal

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT In the Boquet River (NY, USA) a low‐head dam set above a ~200‐m bedrock cascade was removed in 2015. We used radio‐telemetry to assess landlocked Atlantic salmon passage at the remaining cascade (2020, 2022). Across years, 52% of males (13/25) attempted cascade passage whereas females made no discernable attempts (0/11).
