Diverging Food Web Functioning Around Southampton Island, Nunavut: The Influence of Primary Production Supply and Bathymetry. [PDF]

open access: yesEcol Evol
Southampton Island hosts two distinct benthic sub‐webs, north and south. North is deeper, phytoplankton‐driven; South is shallower, more ice‐algae driven. North benthos: bottom‐up control, four trophic levels including apex predators. South benthos: walrus top‐down control, trophic truncation to three levels.

Stress-linked morphological change associated with rearing techniques of hatchery-reliant endemic landlocked Atlantic salmon (Salmo salar m. sebago). [PDF]

open access: yesJ Fish Biol
Abstract Domestication effects caused by hatchery rearing impact various traits in fishes. Lake Saimaa landlocked salmon (Salmo salar m. sebago) have been dependent on hatchery propagation for over 50 years. The population is therefore at risk of hatchery‐induced phenotypes, which can be suboptimal in the wild, thus impacting the long‐term viability of

Zoobenthos of the Lednické rybníky ponds

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014
Qualitative and quantitative composition of macrozoobenthos was studied on the lednické rybníky ponds. Altogether 299 taxa of benthic macroinvertebrates were determined. The values of macrozoobenthos density and biomass ranged between 5–13 021 ind.m–2 and 0.02–79.6 g.m–2 respectively.

The Feeding Behaviour of Fish from the Upper Lake Baikal Watershed of the Eroo River in Mongolia [PDF]

open access: yesMongolian Journal of Biological Sciences, 2005
The upper Selenge watershed in Mongolia is home to some of the world’s unique fish species. In this study we determined the feeding behaviour of selected fish species collected from the main stream of the Eroo River and two of its upstream tributaries,

Differential effects of freshwater browning across fish species: consequences for individual- to community-level fish traits in north temperate lakes. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT The browning of freshwater ecosystems is increasingly evident in temperate and northern regions, with widespread ramifications for lake physics, chemistry, and biology. Contrasting results on how freshwater browning may impact fish have been reported, but there has been no comprehensive examination of how browning may cause cascading effects ...
