Omnivory does not preclude strong trophic cascades

DOI: 10.1002/ecs2.2800
Abstract: Omnivory has been cited as an explanation for why trophic cascades are weak in many ecosystems, but empirical support for this prediction is equivocal. Compared to predators that feed only on herbivores, top omnivores—species that… read more here.

DOI: 10.1016/j.foreco.2018.01.055
Abstract: Abstract Throughout much of the 20th century, the heights of young quaking aspen (Populus tremuloides) in Yellowstone National Park’s northern ungulate winter range were suppressed due to intensive herbivory by Rocky Mountain elk (Cervus elaphus).… read more here.

DOI: 10.1016/j.jmarsys.2017.01.006
Abstract: Abstract The aim of the study was to investigate the relative importance of bottom-up and top-down forcing on trophic cascades in the pelagic food-web and the implications for water quality indicators (summer phytoplankton biomass and… read more here.

Mammal‐induced trophic cascades in invertebrate food webs are modulated by grazing intensity in subalpine grassland

DOI: 10.1111/1365-2656.12744
Abstract: Even though mammalian herbivores can exert strong indirect effects on other animals by altering the vegetation, the study of trophic cascades retains a focus on apex predators and their top-down forces. Bottom-up trophic interaction chains… read more here.

Trophic cascades in 3D: network analysis reveals how apex predators structure ecosystems

DOI: 10.1111/2041-210x.12663
Abstract: 1.Trophic cascade theory predicts that apex predators structure ecosystems by regulating mesopredator and herbivore abundance and behaviour. Studies on trophic cascades have typically focused on short linear chains of species interactions. A framework that integrates… read more here.

Does the strength of cross‐ecosystem trophic cascades vary with ecosystem size? A test using a natural microcosm

DOI: 10.1111/fwb.12897
Abstract: Summary The cascading effect of predators on the functioning of adjacent ecosystems can occur when the life cycles of their prey include two ecosystems. However, there has been little consideration of which habitat attributes can… read more here.

Landscape variation influences trophic cascades in dengue vector food webs
Sign Up to like & getrecommendations! Published in 2018 at "Science Advances"
DOI: 10.1126/sciadv.aap9534
Abstract: Landscapes affect natural dengue vector control through food webs in both terrestrial and aquatic environments. The epidemiology of vector-borne diseases is governed by a structured array of correlative and causative factors, including landscape (for example,… read more here.
