The ecology of ectotherms should be particularly affected by latitude because so much of their biology is temperature dependent. Current latitudinal patterns should also be informative about how ectotherms will have to modify their behavior in response to climate change. We used data from a total of 175 adult black ratsnakes (Elaphe obsoleta) radio-tracked in Ontario, Illinois, and Texas, a lat...

Many marine snails have a biphasic life cycle. They may live in diverse habitats on the ocean floor as adults, but are planktonic in the larval phase where they are subject to oceanic tides and cunents. The link between these two disparate life histoty stages is metamorphosis, a dramatic and ineversible developmental event that transfo1ms a latva physically, physiologically and behaviorally int...

Transport and mortality of newly settled post larvae potentially have a large influence on the population dynamics and adult distributions of coastal benthic species, including the soft-shell clam Mya arenaria. Post-settlement transport typically occurs when boundary shear stresses are high enough to resuspend the surface sediments in which the small clams reside. The objective of the present s...

Phyllophaga lissopyge (Bates) (Coleoptera: Scarabaeidae: Melolonthinae) is reported for the first time from South America. Male sex pheromone response is described for P. lissopyge and two other co-occurring Phyllophaga species. Adults of P. lissopyge and P. menetriesi (Blanchard) flew to traps baited with methyl 2-(methylthio) benzoate whereas adults of P. obsoleta (Blanchard) flew irregularly...
