Evolution 64:1143-50. 2010..In contrast, density dependence of population growth always hinders persistence. With theta-logistic population regulation, a lower value of theta produces a faster initial population decline and a higher extinction risk... - Displacement of flowering phenologies among plant species by competition for generalist pollinatorsCéline Devaux

Department of Biology, University of Oregon, Eugene 97403 1210, USA
Genetica 102:21-7. 1998..Populations with initially high mean fitness and small effective size, N(e) below a few hundred individuals, may be at serious risk of extinction from fixation of deleterious mutations within 10(3) to 10(4) generations... - Mechanisms of rapid sympatric speciation by sex reversal and sexual selection in cichlid fishR Lande
Division of Biology, University of California San Diego, La Jolla 92093, USA
Genetica 112:435-43. 2001..These results may help to explain different patterns and rates of speciation among groups of cichlids, in particular the explosive diversification of rock-dwelling haplochromine cichlids... - Mitochondrial DNA variation, phylogeography and population structure of the Asian elephantP Fernando

Heredity 84:362-72. 2000..Significant genetic differentiation was observed between the mainland and Sri Lanka, and between northern, mid-latitude and southern regions in Sri Lanka... - Population genetic models of male and mutual mate choiceMaria R Servedio

Department of Biology, 0116, University of California - San Diego, La Jolla, CA 92093, USA
New Phytol 166:673-84. 2005..Experimental evidence of reproductive compensation is required to confirm its potential importance in the evolution of plant mating systems.
