- 1From:The Biological Bulletin (Vol. 228, Issue 3) Peer-ReviewedAbstract. Body size plays a crucial role in determining the strength of species interactions, population dynamics, and community structure. We measured how changes in body size affect the trophic relationship between...
- 2From:Canadian Journal of Zoology (Vol. 93, Issue 6) Peer-ReviewedOntogenetic shifts in habitat use are widespread among vertebrates. These niche shifts are often attributed to age-specific patterns of resource use, which are correlated with changes in morphology, diet, and habitat....
- 3From:The Wilson Journal of Ornithology (Vol. 118, Issue 4) Peer-ReviewedNest predation is the main cause of reproductive failure in birds, yet the factors that drive predation pressure, as well as the avian strategies to minimize it, are poorly understood. There is a well-known commensal...
- 4From:Proceedings of the North Dakota Academy of Science (Vol. 59) Peer-ReviewedDeath adders (Acanthophis) are terrestrial elapids who superficially resemble vipers. They are ambush hunters with large, triangular heads, slender necks, and stout bodies (1). Elapids and vipers differ significantly in...
- 5From:Wilson Bulletin (Vol. 115, Issue 2) Peer-ReviewedThis report presents experimental data on the transport of vertebrate prey by the Northern (Great Grey) Shrike (Lanius excubitor). The species is known to use three modes of transport: carrying prey exclusively with the...
- 6From:The Biological Bulletin (Vol. 197, Issue 2) Peer-ReviewedActively vertically migrating mesopelagic copepods are preyed upon by a wide variety of fishes and invertebrates. Their responses to predatory attacks include vigorous escape jumps and discharge of bioluminescent...
- 7From:Science (Vol. 269, Issue 5227) Peer-ReviewedSnowshoe hare populations in the boreal forests of North America go through 10-year cycles. Supplemental food and mammalian predator abundance were manipulated in a factorial design on 1-square-kilometer areas for 8...
- 8From:Ecology (Vol. 77, Issue 2) Peer-ReviewedMathematical models are used to explore the interaction between two prey species that share a common predator. The models assume that the predator experiences density dependence via some mechanism other than prey...
- 9From:Wilson Bulletin (Vol. 107, Issue 4) Peer-ReviewedIn 1989 I observed two instances of red imported fire ant (Solenopsis invicta) predation on newly hatched nestlings of Crested Caracara (Caracara plancus) in the vicinity of the Attwater Prairie Chicken National Wildlife...
- 10From:PLoS ONE (Vol. 7, Issue 1) Peer-ReviewedAuthor(s): Markus Horning 1 , 2 , * , Jo-Ann E. Mellish 3 , 4 Introduction The endangered, western population segment of the Steller sea lion ( Eumetopias jubatus ) has declined to about 20 percent of peak levels...
- 11From:PLoS ONE (Vol. 7, Issue 7) Peer-ReviewedAuthor(s): C. Lidwien Raak-van den Berg 1 , * , Hendrika J. De Lange 2 , Joop C. Van Lenteren 1 Introduction Since its introduction as a biological control agent, Harmonia axyridis (Pallas) (Coleoptera,...

- 13From:Journal of Shellfish Research (Vol. 34, Issue 2) Peer-ReviewedABSTRACT Understanding the impact of ocean acidification and warming on communities and ecosystems is a researcher priority. This can only be achieved through a combination of experimental and field approaches that...
- 14From:Canadian Journal of Zoology (Vol. 84, Issue 4) Peer-ReviewedAbstract: Water molds are widespread in aquatic environments and are important causes of mortality in amphibian and fish eggs. We tested the ability of two species of North American anurans with different breeding...
- 15From:Canadian Journal of Fisheries and Aquatic Sciences (Vol. 63, Issue 5) Peer-ReviewedAbstract: We assessed the effect of fish predation on native and naturalized insect herbivores of the invasive aquatic plant Eurasian watermilfoil (Myriophyllum spicatum) using manipulative field experiments within...
- 16From:Arctic (Vol. 59, Issue 3) Peer-ReviewedABSTRACT. A polar bear (Ursus maritimus) was observed stalking and chasing a flock of adult flightless barnacle geese (Branta leucopsis) in a coastal bay in Hornsund, southwest Spitsbergen. Before chasing the geese, the...
- 17From:The Journal of Arachnology (Vol. 33, Issue 1) Peer-ReviewedABSTRACT. The relationship between running speed and flight distance is an important one in terms of escape from predators, especially in species that may have multiple defensive strategies. In the wolf spider Hogna...
- 18From:Canadian Journal of Zoology (Vol. 85, Issue 6) Peer-ReviewedAbstract: Deforestation may increase predation risk for prey because it may make prey more conspicuous and limit the number of refuges suitable to avoid predators. Therefore, prey may need to increase the magnitude of...
- 19From:Journal of Shellfish Research (Vol. 26, Issue 1) Peer-ReviewedABSTRACT One hundred one individuals of Protothaca staminea were live-collected from Argyle Lagoon (sand/mud substrate) and Argyle Creek (gravel/sand substrate), San Juan Island, Washington and examined for...

Intraguild predation and cannibalism among larvae of detritovorous caddisflies in subalpine wetlands
Comparative data from subalpine wetlands in Colorado indicate that larvae of the limnephilid caddisflies, Asynarchus nigriculus and Limnephilus externus, are reciprocally abundant among habitats - Limnephilus larvae...
