Ecological and evolutionary connections between morphology, physiology, and behavior

Current Zoology 2014年第6期60卷 736-738页

1 Introduction Phenotype variation within populations both provides the raw material for and is the product of evolutionary change. An individual＇s phenotype, defined as the amalgamation of morphology, physiology, and behavior, is highly complex. It has been common to try to isolate each of these aspects of phenotype rather than directly examine their integration. For example, despite the demonstrated importance of single aspects of phenotype for acquiring mates it is well known that signal traits are not evaluated in isolation, but rather in conjunction with associated behaviors, and sometimes with other signal traits （Moiler and Pomiankowski, 1993; Candolin, 2003;

Mimicry： Ecology, evolution, and development

引用

Current Zoology 2012年第4期58卷 604-607页

作者： Pfennig David (Guest Editor) Department of Biology University of North Carolina USA Chapel Hill 27599

1 Introduction Mimicry occurs when one species （the ＂mimic＂） evolves to resemble a second species （the ＂model＂） be-cause of the selective benefits associated with confusing a third species （the ＂receiver＂）. For example, natural selection can favor phenotypic convergence between completely unrelated species when an edible species receives the benefit of reduced predation by resembling an inedible species that predators avoid.

Blurred lines： Scientific and legislative issues surrounding hybrids and conservation

引用

Current Zoology 2015年第1期61卷 128-131页

作者： Suzanne EDMANDS Department of Biological Sciences University of Southern California Los Angeles CA 90089 USA

1 Introduction Hybrids are the result of interbreeding between rec- ognized taxonomic groups such as populations, species or subspecies. This special column focuses particularly on interspecific hybridization. The blurring of lines be- tween neatly defined species causes both academic and practical problems, especially for those still attached to the long-outdated view of species as static, rather than dynamic, entities. Species designations become blurred when previously distinct species come into secondary contact, as well as when incipient species remain con- nected by gene flow. Botanists are generally credited with understanding the importance of hybridization as an evolutionary process that promotes adaptation and produces novel lineages, while zoologists have been characterized as holding to more eugenic views of hy-bridization polluting species integrity.
