Performance-related variation in fitness can manifest as morphological responses to
ecological and evolutionary pressures. Eco-morphological studies often utilize stark binary …

We applied species sensitivity distributions (SSDs), commonly used in chemical risk
assessment, to quantify the impact of water‐flow velocity on the presence of fish species in a …

Background Pelvic brooding is a form of uni-parental care, and likely evolved in parallel in
two lineages of Sulawesi ricefishes. Contrary to all other ricefishes, females of pelvic …

Large yellow croaker (Larimichthys crocea) is one of the most important cultured marine fish
on the southeast coast of China. Its body shape is important for the aquaculture industry …

Understanding the ecological pressures that generate variation in body shape is important
because body shape profoundly affects physiology and overall fitness. Using Fundulus, a …

Biological invasions are recognized as a primary driver of large-scale changes in global
ecosystems. This study addresses ecomorphological variation in head size within and …

The Tule Perch, Hysterocarpus traskii, is a viviparous and externally monomorphic,
internally fertilizing fish. Despite appearing monomorphic, males and females are expected …

The size and shape of the anal and dorsal fin in the blackstripe topminnow Fundulus notatus
from lake and stream habitats across multiple ages and sexes were examined. Differences …

This study describes the growth pattern, condition factor, length at first capture, length at first
maturity, and selection factor (SF) of silver rasbora (Rasbora argyrotaenia) in Sungai Batang …

Variation exists in multiple levels of organization, including between and within species,
populations, and individuals. Fish are ideal organisms to explore questions related to the …
