Trade-offs and constraints are inherent to life, and studies of these phenomena play a
central role in both organismal and evolutionary biology. Trade-offs can be defined …

Amphidromy is a diadromous life history pattern, common in tropical and subtropical
freshwater caridean shrimps, in which adults live, breed and spawn small-sized embryos in …

The functional capacities of animals are a primary factor determining survival in nature. In
this context, understanding the biomechanical performance of animals can provide insight …

Environmental heterogeneity can promote the emergence of locally adapted phenotypes
among subpopulations of a species, whereas gene flow can result in phenotypic and …

Many species of gobiid fishes adhere to surfaces using a sucker formed from fusion of the
pelvic fins. Juveniles of many amphidromous species use this pelvic sucker to scale …

Abstract In the Indo-Pacific region, rivers are inhabited by amphidromous gobies. They are
often subjected to a heavy fishing pressure, highlighting the urgent need to acquire …

Waterfall-climbing gobiids from oceanic islands use a suction-based adhesive mechanism
formed by fused pelvic fins (pelvic sucker) and exhibit rock-climbing behavior during …

Predation is one of the main selective forces in nature, frequently selecting potential prey for
developing escape strategies. Escape ability is typically influenced by several …

Aquatic species can experience different selective pressures on morphology in different flow
regimes. Species inhabiting lotic regimes often adapt to these conditions by evolving low …

Environmental variation is a potent force affecting phenotypic expression. While freshwater
fishes have provided a compelling example of the link between the environment and …
