Non‐consumptive predator effects on prey population size: A dearth of evidence

MJ Sheriff, SD Peacor, D Hawlena… - Journal of Animal …, 2020 - Wiley Online Library
There is a large and growing interest in non‐consumptive effects (NCEs) of predators.
Diverse and extensive evidence shows that predation risk directly influences prey traits …

Divergent perspectives on landscape connectivity reveal consistent effects from genes to communities

RJ Fletcher, NS Burrell, BE Reichert, D Vasudev… - Current Landscape …, 2016 - Springer
Landscape connectivity is increasingly emphasized due to its relevance for interpreting
effects of environmental change. Yet substantial uncertainty remains regarding the …

Predator–prey naïveté, antipredator behavior, and the ecology of predator invasions

A Sih, DI Bolnick, B Luttbeg, JL Orrock, SD Peacor… - Oikos, 2010 - Wiley Online Library
We present a framework for explaining variation in predator invasion success and predator
impacts on native prey that integrates information about predator–prey naïveté, predator and …

Revisiting the classics: considering nonconsumptive effects in textbook examples of predator–prey interactions

BL Peckarsky, PA Abrams, DI Bolnick, LM Dill… - Ecology, 2008 - Wiley Online Library
Predator effects on prey dynamics are conventionally studied by measuring changes in prey
abundance attributed to consumption by predators. We revisit four classic examples of …

From dispersal constraints to landscape connectivity: lessons from species distribution modeling

D Vasudev, RJ Fletcher Jr, VR Goswami… - …, 2015 - Wiley Online Library
Connectivity plays a crucial role in determining the spread, viability, and persistence of
populations across space. Dispersal across landscapes, or the movement of individuals or …

Shorebirds-driven trophic cascade helps restore coastal wetland multifunctionality

C Li, J Chen, X Liao, AP Ramus, C Angelini… - Nature …, 2023 - nature.com
Ecosystem restoration has traditionally focused on re-establishing vegetation and other
foundation species at basal trophic levels, with mixed outcomes. Here, we show that …

Negative effect of turbidity on prey capture for both visual and non‐visual aquatic predators

JCG Ortega, BRS Figueiredo… - Journal of Animal …, 2020 - Wiley Online Library
Turbidity plays an important role in aquatic predator–prey interactions. Increases in turbidity
are expected to reduce prey capture rates, especially for visually oriented predators …

Local community size mediates ecological drift and competition in metacommunities

JL Orrock, JI Watling - … of the Royal Society B: Biological …, 2010 - royalsocietypublishing.org
The outcome of competitive interactions is likely to be influenced by both competitive
dominance (ie niche-based dynamics) and ecological drift (ie neutral dynamics governed by …

Field evidence for pervasive indirect effects of fishing on prey foraging behavior

EMP Madin, SD Gaines, RR Warner - Ecology, 2010 - Wiley Online Library
The indirect, ecosystem‐level consequences of ocean fishing, and particularly the
mechanisms driving them, are poorly understood. Most studies focus on density‐mediated …

The cost of safety: refuges increase the impact of predation risk in aquatic systems

JL Orrock, EL Preisser, JH Grabowski, GC Trussell - Ecology, 2013 - Wiley Online Library
Although use of refuge habitats by prey can reduce their risk of predation, refuge use may
also involve costs such as increased within‐refuge competition for resources. Despite the …
