| discordant patterns of evolutionary differentiation in two neotropical treefrogs. | comparative studies of codistributed taxa test the degree to which historical processes have shaped contemporary population structure. discordant patterns of lineage divergence among taxa indicate that species differ in their response to common historical processes. the complex geologic landscape of the isthmus of central america provides an ideal setting to test the effects of vicariance and other biogeographic factors on population history. we compared divergence patterns between two codistrib ... | 2009 | 19368645 |
| negative synergism of rainfall patterns and predators affects frog egg survival. | 1. the importance of rainfall is recognized in arid habitats, but has rarely been explored in ecosystems not viewed as rainfall limited. in addition, most attempts to study how rainfall affects organismal survival have focused on long-term rainfall metrics (e.g. monthly or seasonal patterns) instead of short-term measures. for organisms that are short lived or are sensitive to desiccation, short-term patterns of rainfall may provide insight to understanding what determines survival in particular ... | 2009 | 19486379 |
