Factors affecting intraspecific diet variation of ducklings: Niche partitioning in a heterogeneous landscape?

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Variability in resource use within populations of free‐ranging animals can influence demographic and evolutionary processes. Yet in many ecological systems, the extent of intra‐population variation in the resources that animals consume and the environmental factors that contribute to this variance remain poorly understood. For example, dietary

Mitochondrial DNA reveals genetic structuring of Pinna nobilis across the Mediterranean Sea [PDF]

open access: yes, 2013
Pinna nobilis is the largest endemic Mediterranean marine bivalve. During past centuries, various human activities have promoted the regression of its populations.

Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 8, Page 505-516, December 2025.
Epithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.

Using stable isotopes to describe the trophic structure of gelatinous zooplankton across the deep pelagic

open access: yesLimnology and Oceanography, Volume 70, Issue 12, Page 3634-3649, December 2025.
Abstract Although gelatinous zooplankton are key members of marine ecosystems and food webs, their trophic ecology is poorly described across the deep pelagic. We used stable carbon (bulk tissue) and nitrogen (bulk tissue and amino acid) isotope analysis to estimate the trophic positions (TPs) of abundant gelatinous zooplankton (chaetognaths ...

Feeding by slugs on maize imposes variable productivity costs but can induce compensatory growth under some conditions

open access: yesPest Management Science, Volume 81, Issue 12, Page 8419-8430, December 2025.
Slugs can challenge crop plants grown in no‐till fields. Our results confirm that higher levels of slug feeding can be detrimental to maize plants, but low levels of herbivory by slugs can unexpectedly increase plant growth and occasionally yield. Abstract BACKGROUND In contrast to herbivorous insect pests, relatively little attention has been given to
