Costs of passive dispersal in fragmented landscapes

In this post, Brittany Teller (@brittzinator) describes her recent paper with co- authors Adam Miller & Katriona Shea “Conservation of passively dispersed organisms in the context of habitat degradation and destruction“ Leaving the natal location (hereafter, “dispersal”) can be a critical part of many species’ life cycles. If dispersing individuals help establish new populations, this colonization can help keep connected metapopulations viable in the face of disturbances … Continue reading Costs of passive dispersal in fragmented landscapes

A dilemma in conservation practice

In this post, Johan du Toit, focuses on a dilemma in conservation practice: should we do what seems best now or gather more information to (maybe) come up with a better plan? Johan handled the recent paper by Sean Maxwell (@Sean_Ecology)  et al. “How much is new information worth?

Silent Spring redux? Insecticides cascade up a food chain to poison carnivores

In this post, Ian Kaplan discusses a paper he recently handled by Margaret Douglas, Jason Rohr and John Tooker “Neonicotinoid insecticide travels through a soil food chain, disrupting biological control of non-target pests and decreasing soybean yield.“. The authors have also written a practitioner summary  and a press release “Insecticides foster ‘toxic’ slugs, reduce crop yields” for this paper. Despite being published >50 years ago, almost everyone … Continue reading Silent Spring redux? Insecticides cascade up a food chain to poison carnivores
