Northern pintail nest site selection, nest success, renesting ecology and survival in the intensively farmed prairies of southern Saskatchewan: an evaluation of the ecological trap hypothesis
… 1990s. My primary objectives were to test the “ecological trap hypothesis” on a landscape level by examining pintail nest site selection and nest success in a highly agricultural environment in southern Saskatchewan. I also used radiotelemetry to estimate renesting and breeding season survival …

Dynamics of Social-ecological Traps: The Case of Small-scale fisheries in the Philippines
… interactions that drive a system into a social-ecological trap, a persistently unsustainable and undesirable social-ecological system. Recent research on social-ecological traps points to some gaps in the conceptualisation and analysis of these resilient yet pathological social-ecological …

Impact of Light Pollution on Species Interactions
… I found that light pollution induces an ecological trap for moths.</p> <p>I evaluated the importance of light pollution in structuring moth communities by collecting moths from a wide variety of prairie fragments with different habitat sizes, vegetation, and light pollution levels to …

THE ROLES OF FOOD AND PREDATION IN SHAPING ADAPTIVE AND MALADAPTIVE BEHAVIORS IN POSTFIRE BIRD SPECIES
… the organism is said to be caught in an ‘ecological trap’. Herein, I develop a conceptual model to explain how an ecological trap might work, outline the specific criteria that are necessary for demonstrating the existence of an ecological trap, and provide tools for researchers to use in …

Direct and indirect effects of native and invasive plants on mosquito ecology
… blackberry) was identified to function as an ecological trap for Cx. pipiens, attracting gravid females to oviposit and yet deleterious to larvae yielding low emergence rates. Subsequent laboratory bioassays in which first instar larvae were exposed to mixtures of leaves from different plant …

Grassland and breeding bird use of moist-soil wetlands managed for waterfowl
… at a high risk of flooding to avoid creating an ecological trap for breeding birds. In moist-soil wetlands that are disconnected from the Illinois River and less likely to flood, I recommend an early drawdown to allow moist-soil vegetation to grow and provide habitat for grassland birds.

Caracals as sentinels for metal exposure in a human-transformed landscape
… global evidence base suggesting cities act as ecological traps for wildlife, threatening their long-term health and persistence in these landscapes. Therefore, it is crucial that cities work to reduce the large quantities of chemical pollutants released into their surrounding environment. In …

Conservation in a changing world: assessing the conservation status of an agriculturally adapted species, the blue crane
… that the Western Cape wheatlands may pose an ecological trap for the species, and that declines are likely being driven by poor breeding productivity and recruitment (Appendix 1). Drawing from the literature, and interviews with farmers (Appendix 2), I contextualise Blue Crane conservation in …
