Global Change Likely to Promote the Expansion of the Quagga Mussel (Dreissena bugensis) in Europe

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim Invasive aquatic species are a pressing concern for environmental managers due to their significant impacts and high eradication costs. The Ponto‐Caspian region is a notable source of aquatic invasive species, with over 40 invaders currently affecting freshwater ecosystems throughout Europe.

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

open access: yesJournal 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.

Unexpected trophic diversity in the endemic fish Orestias chungarensis in a high‐altitude freshwater ecosystem, Lake Chungará (4520 m), northern Chile

open access: yesJournal of Fish Biology, EarlyView.
Abstract Orestias chungarensis Vila & Pinto, 1986 is a small‐bodied (max fork length = 120 mm) cyprinodontiform fish with a very restricted global distribution. The species is limited to a single, small (283 km2), high‐altitude (4520 m) catchment located in the Altiplano of northern Chile. Until the late 20th century, O.

A decline in the energy content of forage fish in the Bay of Biscay

open access: yesJournal of Fish Biology, EarlyView.
Abstract Planktonic production fuels the base of marine food webs and can mediate energy accumulation in consumers but is affected by several anthropogenic pressures. Our understanding of how shifts in prey quality at various trophic level shape marine food webs remains poor.
