Abstract The instantaneous rate of food intake for mammalian herbivores is controlled by the geometry of plant communities which regulates the encounter rate with bites, bite mass and the processing rate of bites. The geometry of plant canopies is fractal because bite density only occupies a fraction of the entire dimension of the tree canopy and ...

Abstract Feeding habits and interspecific trophic niche overlap of two sympatric predators, the pine marten Martes martes and the red fox Vulpes vulpes, were studied in a deciduous forest habitat in Hungary with conditions of differing abundance and dominance in the rodent community.

Importance of ecological compensation areas for small mammals in intensively farmed areas
Abstract Small mammals make up an important link in the food chain as many predator species feed on them. There are indications that small mammal populations in Europe are declining due to the intensification of agriculture. According to national legislation, farmers in Switzerland have to cultivate at least 7% of their land as ecological compensation ...

Abstract Invasive alien species rank among the world's greatest threats to biodiversity and cause huge economic losses. Eradication is a key management strategy for newly introduced pests, but it is frequently discarded due to the high costs. When populations become established and conflicts increase, policy‐makers often resort to permanent population ...

Abstract This study examines how the distribution and abundance of prey species influenced arctic fox Alopex lagopus diet on Svalbard during the summers of 1997, 1998 and 1999. The arctic fox together with the glaucous gull Larus hyperboreus are the only predators of this terrestrial ecosystem, and during summer the potential prey are confined to a few

Using food quality and retention time to predict digestion efficiency in geese
Abstract Investigations of food digestibility are important in nutritional studies of herbivores, but accurate assessments in the field are usually difficult and time consuming. This study explored the possibility of predicting digestibility and metabolisability of organic matter from the chemical composition and retention time of food in barnacle ...

Abstract Pyrethroid resistance in the redlegged earth mite (Halotydeus destructor) continues to be a persistent and expanding problem across the grain belt of Australia, requiring ongoing monitoring to detect emerging local resistance issues. Detection of field resistance in H. destructor currently relies upon the collection and transport of live mites,
