When sounds collide: the effect of anthropogenic noise on a breeding assemblage of frogs in Belize, Central America

摘要: Many organisms depend on acoustic communication for myriad functions, and have evolved behaviours to minimize effects of naturally occurring interference. However, as habitats are subject increased alteration, anthropogenic noise becomes unavoidable, how animals overcome such interference is not well understood. In most ecosystems, only a subset frog species associated with disturbed habitats; the ability these exogenous suggests that habitat associations may be related species' response noise. We tested hypothesis frogs largely undisturbed forest would less likely increase call output in than those or open habitat. While this relationship was significant, we found slight trend supporting hypothesis. then asked whether affects chorus tenure at individual- chorus-levels. Male exposed decreased both number days present nightly duration relative controls. Because females generally join choruses late night breed, shown here substantially decrease reproductive success; thus, environment play an important role shaping population dynamics amphibian declines.
