It has been hypothesized that inter‐specific competition will reduce species niche utilization
and drive morphological evolution in character displacement. In the absence of a competitor …

When competing for food or other resources, or when confronted with predators, young
animals may be at a disadvantage relative to adults because of their smaller size …

Because selection on juvenile life-history stages is likely strong, disproportionately high
levels of performance (eg, sprint speed, endurance, etc.) might be expected. Whereas this …

The role of learning in behaviour is well known for many animal taxa, including teleost
fishes, insects, birds and mammals. However, its importance to sharks in everyday …

The shape development through ontogeny of the gilthead sea bream Sparus aurata was
studied by means of geometric morphometry and elliptic Fourier analysis. In parallel …

Background. The round goby, Neogobius melanostomus (Pallas, 1814), is a recent invader
in the Curonian Lagoon, SE Baltic Sea. As invasive species are among the most severe …

Abstract Theory indicates that competing species coexist in a community when intraspecific
competition is stronger than interspecific competition. When body size determines the …

Simple Summary Currently plant products are used to partially replace fish meals and oils in
fish diets. However, the excessive use of these products can cause nutritional imbalances …

The trophic niche of aquatic generalist predators is influenced by ontogeny, habitat
characteristics, availability and type of prey, and competitive interactions. Many interrelated …

Ontogenetic diet shifts are an important component of the early life history of many fishes.
Successfully shifting diets affects not only individuals but also populations and communities …
