Caddisfly behavioral responses to drying cues in temporary ponds: Implications for effects of climate change.
(The University of Chicago Press, 2016-02-11)
Aquatic organisms that live at high latitudes and elevations are especially vulnerable to climate-change-induced alterations in snowpack, snowmelt, and evaporation rates, all of which affect basin filling and drying dates. ...
Consumptive and nonconsumptive effects of cannibalism in fluctuating age-structured populations
(Ecological Society of America, 2010)
Theory and empirical studies suggest that cannibalism in age-structured populations can regulate recruitment depending on the intensity of intraspecific competition between cannibals and victims and the nature of the ...
Temporal shift of diet in alternative cannibalistic morphs of the tiger salamander
(Linnean Society of London, 2006-01-15)
Evolutionary theory predicts that alternative trophic morphologies are adaptive because they allow a broad use of resources in heterogeneous environments. The development of a cannibal morphology is expected to result in ...
The role of larval cases in reducing aggression and cannibalism among caddisflies in temporary wetlands
Larvae of wetland caddisflies supplement their detrital diets with animal material. In some species this supplement is obtained by preying on other caddisflies. In this study, we conducted a series of laboratory experiments ...
Intraguild predation and cannibalism among larvae of detritivorous caddisflies in subalpine wetlands
(Ecological Society of America, 1996-12-01)
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 dominate ...
Niche overlap and the potential for competition and intraguild predation between size-structured populations.
(Ecological Society of America, 1992)
Many populations are heterogeneous collections of different sizes or stages of conspecifics. Existing overlap indices do not account for the size—/stage—structured nature of these populations. In this paper I present new ...
