Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.ABSTRACT Parasites affect hosts in interaction with the entire ecological community. This is particularly evident for trophically transmitted parasites, such as Dibothriocephalus tapeworms, which infect multiple intermediate fish hosts, potentially reducing their fitness and suitability for human consumption.

Fisheries Oceanography, Volume 35, Issue 5, Page 777-794, September 2026.ABSTRACT Japanese anchovy (Engraulis japonicus) is the most abundant fish in the East China Sea (ECS) and an important fishery resource throughout its life stages. Using samples collected along the ECS shelf‐break in April over a 22‐year period (2001–2022), we examined the horizontal distribution and interannual variability of larval density (mean ...

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.ABSTRACT Clinostomum complanatum infection is a trematode parasite infecting diverse freshwater fish hosts, causing pathological damage and economic losses. Despite its veterinary and public health importance, its global burden remains insufficiently quantified. This study aimed to assess the global burden of C.

, 2021 The ecological communities we observe today are a product of the bidirectional interactions between ecological and evolutionary processes. Although the effects of ecological processes on population divergence and speciation have been studied extensively, far less is known about the effects of divergence and speciation on ecological dynamics.

The influence of rivers on seabird foraging ecology
Biological Reviews, Volume 101, Issue 4, Page 1704-1734, August 2026.ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Stayin' alive: Strategies to reduce predation on target species are context dependent
Ecosphere, Volume 17, Issue 8, August 2026.Abstract Restoration and conservation efforts often aim to reduce predation, particularly by reducing interactions with nonnative predators in heavily disturbed and invaded ecosystems. For Chinook salmon Oncorhynchus tshawytscha, a highly valued but declining fishery, potentially useful freshwater rearing habitat restoration strategies may include ...

Ecology and Evolution, Volume 16, Issue 7, July 2026.Eurasian beavers significantly enhance bird diversity and abundance by creating wetland habitats, with 23% higher bird numbers and more unique species at beaver ponds compared to unaffected streams. The size of water surfaces was the key factor influencing species richness, particularly benefiting birds that rely on aquatic environments.
