Age‐related trends in niche position and specialization in Neotropical vertebrates

open access: yesEcography, Volume 2026, Issue 7, July 2026.
Species' niche positions and breadths within a region's environmental space, measured through ecological niche factor analysis (ENFA) as marginality and specialization, can reflect evolutionary constraints related to lineage age. The ‘internal incumbency' hypothesis predicts that older species, due to competitive preemption, occupy more central niche ...

A practical guide to species trend detection with unstructured data using local frequency scaling (Frescalo)

open access: yesEcography, Volume 2026, Issue 7, July 2026.
Accurately measuring biodiversity change remains a central challenge in ecology. Beyond the general idea of quantifying temporal species frequency changes, several sampling‐related biases in data collection remain key methodological challenges to consider. Long‐term standardized ecological data are rare, and most available datasets exhibit considerable

Climate change impacts on California's foundational trees: Demographic shifts are already underway

open access: yesEcosphere, Volume 17, Issue 7, July 2026.
Abstract Climate change is a leading threat to global biodiversity. Research on climate change impacts on foundational species, which underlie the structure and function of ecosystems, is critical to developing effective conservation responses. To better understand the landscape of existing research and identify research needs, we conducted a scoping ...

Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status

open access: yesNordic Journal of Botany, Volume 2026, Issue 7, July 2026.
Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.
