Unraveling multipredator impacts in salmon‐bearing rivers using quantitative DNA metabarcoding

open access: yesEcological Applications, Volume 35, Issue 8, December 2025.
Abstract Ecological impacts of invasive species are mounting as their numbers and geographic extent continue to increase. Across extensive parts of their range, Pacific salmon (Oncorhynchus spp.) smolts face an expanding gauntlet of nonnative predators during their seaward migration.

Fatty Acids and Stomach Contents Reveal Dietary Overlaps of Two Prospering Squid Species in the North Sea

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Distribution ranges of cephalopods are expanding worldwide and their abundances are increasing due to ocean warming. Recently, the broadtail shortfin squid Illex coindetii (Ommastrephidae) expanded into the North Sea where it established a successful spawning stock beside the resident veined squid Loligo forbesii (Loliginidae). Stomach content analysis

Biology and Food Habits of the Invasive Snail Allopeas gracile (Gastropoda: Subulinidae)

open access: yesFlorida Entomologist, 2017
The biology of the widely occurring but poorly known terrestrial snail Allopeas gracile (Hutton, 1834) (Gastropoda: Subulinidae) was determined, emphasizing food relationships. Isolated snails reproduced without cross fertilization.

Delineating Diversity‐Based Freshwater Bioregions by Integrating Fish and Macroinvertebrates With Species Distribution Models and Spatial Clustering

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
We integrated fish and macroinvertebrate data with species distribution models and spatial clustering to delineate coherent freshwater bioregions. The resulting bioregions captured complementary biodiversity patterns and key transition zones more effectively than single‐taxon or UPGMA clustering.

Assessing the Relationship Between Macroinvertebrate Metrics and Fine Sediment Index for Ecological Biomonitoring in the Little Akaki River, Addis Ababa, Ethiopia

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Habitat quality had a positive correlation with percentage of Ephemeroptera, percentage of EOT, and Shannon diversity index (r = 0.833, r = 0.880, and r = 0.939, respectively). PSI had positive correlation with number of taxa, and ASPT‐ETHbios (r = 0.819, and r = 0.798, respectively). Most sites were heavily sedimented.

Effects of BPA in snails : Oehlmann et al. respond [PDF]

open access: yes, 2006
We welcome critical appraisals that help to provide balance; however, Dietrich et al. gave an unjustified reproach. We feel that Dietrich’s position is severely compromised because he serves as an expert for the bisphenol A (BPA) Industry Group (Brussels,

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

Phylogenetic analysis of the Camaenidae (Mollusca: Stylommatophora) with special emphasis on the american taxa [PDF]

open access: yes, 2003
The monophyly of the land snail family Camaenidae has been in doubt due to a disjunct bihemispheric distributional pattern and to the lack of morphological synapomorphies.
