Trophic cascades and trophic trickles in pelagic food webs

Landscape variation influences trophic cascades in dengue vector food webs

The epidemiology of vector-borne diseases is governed by a structured array of correlative and causative factors, including landscape (for example, rural versus urban), abiotic (for example, weather), and biotic (for example, food web) factors. Studies of mosquito-borne diseases rarely address these multiple factors at large spatial scales, which limits insights into how human alterations of la...

Trophic cascades promote threshold-like shifts in pelagic marine ecosystems.

Fisheries can have a large impact on marine ecosystems, because the effects of removing large predatory fish may cascade down the food web. The implications of these cascading processes on system functioning and resilience remain a source of intense scientific debate. By using field data covering a 30-year period, we show for the Baltic Sea that the underlying mechanisms of trophic cascades pro...

M issing Lynx and Trophic Cascades in Food Webs: A Reply to Ripple et al

Ripple et al. (2011) proposed a hypothesis th a t the recovery o f gray wolves {Canis lupus) may positively affect the viahility o f threatened C anada lynx {Lynx canadensis) populations in the contiguous U nited States th rough indirect species interactions. Ripple et al. (2011) proposed 2 key trophic linkages connecting w olf restoration w ith lynx recovery. First, recovering w olf population...
