Piscivorous predators at the apex of aquatic food webs are thought to exhibit foraging behaviours that depend on environmental conditions. Walleye (Sander vitreus), for example, is a freshwater predator that is most active under low light conditions.

Organisms occupying high trophic positions in food webs are proposed to exert a stabilizing effect on ecosystems under changing conditions. A possible mechanism underlying this phenomenon is higher mobility of large-bodied predators, which allows bro

The activity of muscle glycolytic enzymes scales positively with body size in active fish, a phenomenon thought to counter the increased costs of burst swimming faced by larger individuals. Recent work argued that changes in these enzymes during onto

An in vitro experiment was carried out using the Hohenheim gas production technique to evaluate 24-h gas production, apparently and truly degraded dry matter (DM), partitioning factor (PF), short chain fatty acids, crude protein (CP) and carbohydrate

The objective of this study was to improve knowledge regarding the amino acid profile of the insoluble portion of ingested forage escaping rumen degradation. Six forage categories were analyzed. Categories varied in botanical composition and each con

Predators tend to be large and mobile, enabling them to forage in spatially distinct food web compartments (e.g. littoral and pelagic aquatic macrohabitats). This feature can stabilise ecosystems when predators are capable of rapid behavioural respon

Wilting grass prior to ensiling generally increases the dry matter (DM) intake but the effect of wilting on animal performance is still poorly understood. There is a need to improve understanding of the effects of wilting on the nutritional component

Rumen insoluble feed crude protein (CP) escaping degradation (RUP) was estimated from a variety of forages using two in vitro procedures: the Cornell protein fractionation procedure and the enzymatic degradation procedure by Streptomyces griseus prot

As protein evaluation systems are evolving, they are increasing in their sophistication and complexity. In almost all systems an estimate of microbial crude protein (MCP) and ruminally undegraded feed CP (RUP) must be available. A problem lies in the
