Moult is associated with higher diversity of food items in the diet of Common Bulbuls (Pycnonotus barbatus) in Cameroon

open access: yesIbis, EarlyView.
Moult is an essential part of birds' annual cycle, and requires sufficient intake of energy and nutrients, but we understand little about how such nutritional requirements are met by wild birds. Using faecal metabarcoding, we analysed the diet of moulting and non‐moulting Common Bulbuls Pycnonotus barbatus, captured in Cameroon.

Foraging niche partitioning within a recently established guild of falcons

open access: yesIbis, EarlyView.
Ecological theory predicts that coexisting species should exhibit realized niche differentiation to minimize competition. However, little is known about patterns of niche differentiation when ‘newcomer’ species spontaneously colonize a new region, leading to novel sympatric conditions.

Identifying conservation hotspots and assessing species commonness and rarity: Baseline arthropod diversity in German nature reserves via national Malaise trap monitoring

open access: yesInsect Conservation and Diversity, EarlyView.
Conducted a year‐long Malaise trap monitoring study across Germany, revealing 14,445 OTUs, including 8,589 assigned species, highlighting extensive small‐scale and largely undescribed diversity. Identified 17 invasive species, five of which are new records for Germany, underscoring the need for continuous monitoring to manage invasive species ...
