Environmental and Evolutionary Forces Shaping Penguin Geographic Limits

Journal of Biogeography, EarlyView.
ABSTRACT Aim Penguins are seabirds exclusively found in the Southern Hemisphere, with their existence dating back to the late Cretaceous. Despite their exceptional dispersal capabilities, which allow them to inhabit a wide range of environments—from polar regions to temperate zones, and even near the Equator—penguins are absent in the Northern ...

Morphological covariates of the ontogenetic shift from nauplii to copepodite prey in larval fish

Journal of Fish Biology, EarlyView.
Abstract Larval fish are active planktonic predators, with many species feeding initially on copepod nauplii and gradually shifting their selection to copepodites. This study evaluated whether it is possible to develop a general widely applicable empirical model to describe the transition from feeding on copepod nauplii to copepodites in relation to ...

Modelling fishing‐induced evolution in pikeperch (Sander lucioperca) and vendace (Coregonus albula), Lake Oulujärvi, as template for ecosystem model

Journal of Fish Biology, EarlyView.
Abstract Fishing‐induced evolution can impact fish trait distributions, with previous studies highlighting declines in size and age at maturation. However, the effects on fish growth remain less understood, and different fishing methods may exert distinct selection pressures on populations.

Postprandial oxygen consumption, ammonia excretion and carbon dioxide production of channel and blue catfish

Journal of Fish Biology, EarlyView.
Abstract Fishes undergo dramatic physiological changes upon consumption of a meal, including an increase in oxygen consumption to support the metabolic cost of digestion [specific dynamic action (SDA)] and an increase in the excretion of ammonia. Channel catfish (Ictalurus punctatus) and blue catfish (I.
