In obligately siblicidal bird species, aggressive behavior by a dominant chick results in a fixed brood size of one, yet these species usually show clutch size variation between individuals. Simmons proposed that variation in clutch size in obligatel

Summary 1 Natural selection is expected to optimize clutch size, but intrapopulation variation is maintained in many bird species. The Nazca booby provides a simple system in which to investigate clutch size evolution because clutch size and brood si

A variety of organisms regularly produce more offspring than they raise. Despite the apparent energetic waste of such a reproductive tactic, overproduction may be favored by natural selection in some cases. One such case is when surplus offspring can

We examine the motion of soft drink cans rolling down an incline as a function of the amount of water in the can. Our observations show this behavior to be remarkably complex. We introduce models suggested by the experimental results which describe t

The effect of chelation of zinc by diethyldithiocarbamate (DEDTC) on bursting of CA3 pyramidal cells induced by mixed antidromic plus orthodromic activation of mossy fibers (MP) in hippocampal slices was studied. Slices perfused in artificial cerebro

We present the results of a coupled experimental and numerical study into the shock induced combustion of ethylene in a flow over a rectangular ramp. We describe the experimental apparatus and compare the results with numerical model predictions. The
