Ecological Research, Volume 41, Issue 3, May 2026.We compared the diet and assessed geographic and seasonal variations in the isotopic niches of red‐footed boobies across three Indian Ocean atolls. Our results demonstrate plasticity in both diet and trophic niche, likely driven by local environmental conditions, breeding stages, and colony‐specific factors.

Mode of miniaturisation influences body shape evolution in New World anchovies (Engraulidae) [PDF]
Journal of Fish Biology, 2019 AbstractWe explored the macroevolutionary dynamics of miniaturisation in New World anchovies by integrating a time‐calibrated phylogeny, geometric morphometrics and phylogenetic comparative methods. We found that the paedomorphic species Amazonsprattus scintilla occupies a novel region of shape space, while the dwarf species Anchoviella manamensis has ...

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.ABSTRACT This study investigates the widespread degradation of river ecosystems in Bangladesh and its impact on fish biodiversity and identifies potential strategies for ecosystem restoration. Combining community perceptions from focus group discussions (FGDs) with fish market study for spatial analyses of fish species diversity across the Barak–Meghna,

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.Finite mixture models revealed that older, larger harbor seals specialize in salmon predation at setnets in Hokkaido, Japan, suggesting targeted management strategies focusing on these specialist individuals could effectively reduce fishery conflicts while protecting the broader seal population.
