Bird extinctions shift bill–flower trait matching in Hawaiian lobelioids

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Species extinctions can reorganize ecological interactions by altering the distribution of functional traits within communities. These traits structure how species interact, influencing whether encounters result in mutualistic or antagonistic outcomes.

Global meta‐analysis reveals urban‐associated behavioural differences among wild populations

Journal of Animal Ecology, EarlyView.
Urbanization drives rapid phenotypic change, yet broad patterns of behavioural responses remain unclear. Using a global phylogenetic meta‐analysis, we show urban populations exhibit increased boldness, aggression, exploration and activity—especially in birds—highlighting consistent behavioural shifts and revealing major taxonomic gaps that limit our ...

Pollinator community composition and pollen resource use in calcareous grasslands under different landscape contexts across Europe

Journal of Animal Ecology, EarlyView.
In this paper, we show that pronounced differences in pollinator communities exist between grasslands embedded in contrasting agricultural landscape contexts. Opportunistic foraging strategies of most pollinators resulted in large interaction turnover, but these shifts did not translate into major changes in overall network structure, most likely as a ...

Optimising daily sampling of plant–bee interaction networks

Journal of Animal Ecology, EarlyView.
Daily variation in ecological interaction networks is rarely quantified due to limited temporal sampling, yet network structure may change substantially within a single day. We show that plant–bee networks exhibit strong intraday shifts in composition and structure, and that sampling distributed across key daily periods better captures network ...

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

Insect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

Insect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Characterization of the dynamic microbiome evolution across thrips species

Insect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.
