Extinction and Survival

چکیده
When we hear the word extinction, most of us immediately think of dinosaurs and woolly mammoths and cataclysmic events precipitating their extinction. Some of us are also aware of current extinction threats and recent extinctions, but few, if any, of us understand the varying and complex circumstances under which extinction actually happens. It turns out that extinction and species survival are closely linked through species diversity in the ecosystem.

Pulsed electromagnetic field attenuated PTSD-induced failure of conditioned fear extinction
Objective(s): This study aimed to determine whether exposure to pulsed electromagnetic field (PEMF) can impair behavioral failure as induced by PTSD, and also its possible effects on hippocampal neurogenesis. PEMF was used as a non-invasive therapeutic tool in psychiatry.Materials and Methods: Male rats were divided into Control-Sham exp...

متن کاملCan life history predict the effect of demographic stochasticity on extinction risk?
Demographic stochasticity is important in determining extinction risks of small populations, but it is largely unknown how its effect depends on the life histories of species. We modeled effects of demographic stochasticity on extinction risk in a broad range of generalized life histories, using matrix models and branching processes. Extinction risks of life histories varied greatly in their se...
