| intestinal parasites of raccoons (procyon lotor) from southwest british columbia. | this is the first extensive survey of metazoan parasites (particularly of the roundworm baylisascaris procyonis) from the intestines of raccoons in british columbia. the sample collected in 1997-1998 consisted of 82 raccoons that had been sick or had been killed accidentally by automobiles. fifteen parasite taxa were found: 3 nematodes, 9 digenetic trematodes, 2 acanthocephalans and 1 cestode. ten of these parasites constitute new host records for raccoons, including 4 digenetic trematodes that ... | 2000 | 10805249 |
| mammalian mesopredators on islands directly impact both terrestrial and marine communities. | medium-sized mammalian predators (i.e. mesopredators) on islands are known to have devastating effects on the abundance and diversity of terrestrial vertebrates. mesopredators are often highly omnivorous, and on islands, may have access not only to terrestrial prey, but to marine prey as well, though impacts of mammalian mesopredators on marine communities have rarely been considered. large apex predators are likely to be extirpated or absent on islands, implying a lack of top-down control of me ... | 2014 | 25234377 |
| do large carnivores and mesocarnivores have redundant impacts on intertidal prey? | the presence of large carnivores can affect lower trophic levels by suppressing mesocarnivores and reducing their impacts on prey. the mesopredator release hypothesis therefore predicts prey abundance will be higher where large carnivores are present, but this prediction assumes limited dietary overlap between large and mesocarnivores. where dietary overlap is high, e.g., among omnivorous carnivore species, or where prey are relatively easily accessible, the potential exists for large and mesoca ... | 2017 | 28085962 |
