Ecological Character Displacement in a Variable Environment
We analyzed a simple genetic model of ecological character displacement in a fluctuating environment. Character states of two identical, competing species were determined by a single-gene, two-allele model. In each generation, the carrying capacity of different segments of a uniform resource spectrum fluctuated randomly. Interand intraspecific exploitation competition reduced litnesses of simil...
متن کاملEcological character displacement and speciation in sticklebacks.
We present evidence of ecological character displacement among species of threespined sticklebacks that inhabit small lakes of coastal British Columbia. Geological data suggest that the populations resulted from multiple divergence and speciation events over the past 13,000 yr. In lakes with two species, one is invariably "limnetic" in morphology and habitat, and the other is "benthic." Other l...
متن کاملEcological Character Displacement in a Lizard
synopsis. Two species of subterranean skinks (Typhlosaurus) are sympatric in part of the southern Kalahari Desert. The geographic range of the smaller species (T. gariepensis) is entirely included within that of the larger one (T. lineatus). Snout-vent lengths, head dimensions, proportional head lengths, and prey size of T. lineatus are larger in sympatry than in allopatry. Morphological and di...
متن کاملEcological character displacement and the study of adaptation.
T study of adaptation—a central issue in biology since before the time of Darwin—is currently enjoying a renaissance. Ridiculed two decades ago as following a panglossian paradigm (1) that promulgated ‘‘just so stories’’ rather than testing hypotheses, evolutionary biology has become a vibrant field in which a wide variety of methods—ranging from molecular developmental biology to manipulative ...
