Use of Citizen Science to Determine Prey Partitioning Between Two Coastal Raptors

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
In Australia, Eastern Osprey (Pandion haliaetus cristatus) and White‐bellied Sea‐Eagle (Haliaeetus leucogaster) occupy the same ecological niche and are suspected of partitioning prey resources. This study investigated this through evaluating the breadth, overlap and partitioning of diets recorded from social media posts.

Ostracod Genetic Variability in Response to Lake Level‐Driven Salinity Dynamics in Nam Co, Central Tibetan Plateau, in the Past Two Millennia

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Using sedimentary ancient DNA metabarcoding on a two‐millennia sediment core from Nam Co (Tibetan Plateau), the study reconstructs ostracod community shifts and genetic diversity in response to hydrological and climatic changes. Species richness peaked during moister intervals, while alternating dominance during the Medieval Climate Anomaly and Little ...

Biodiversity of macrozoobenthos in a large river, the Austrian Danube, including quantitative studies in a free-flowing stretch below Vienna: a short review [PDF]

open access: yes, 2005
The Danube is ca. 2850 km in length and is the second largest river in Europe. The Austrian part of the Danube falls 156 metres in altitude over its 351 km length and, since the early 1950s, the river has been developed into a power-generating waterway ...
