Stable isotope analyses of web-spinning spider assemblages along a headwater stream in Puerto Rico.

abstract：:In highly biodiverse systems, such as coral reefs, prey species are faced with predatory threats from numerous species. Recognition of predators can be innate, or learned, and can help increase the chance of survival. Research suggests that parental exposure to increased predatory threats can affect the development, b...
