PREMISE OF THE STUDY: Gene flow through dispersal of seeds and pollen is a fundamental determinant of spatial genetic structure (SGS) in natural populations of trees at different spatial scales. Within continuous populations, ...

Variations in communication systems profoundly affect bird evolution. Vocalizations mediate species recognition and therefore intra-specific variation may lead to reproductive isolation, ultimately resulting in speciation. ...

Assessing the relative importance of geographical and environmental factors to the spatial distribution of genetic variation can provide information about the processes that maintain genetic variation in natural populations. ...

Geographical variation of bird vocalizations may be related to factors influencing sound production and sound propagation. If birds, e.g. the Great Antshrike (Taraba major), produce vocalizations that develop normally in ...

This case study examines the pollen dispersal distance, pollen dispersal patterns and intra-family genetic structure for isolated trees in pastures of the bat-pollinated Neotropical tree species Hymenaea stigonocarpa using ...
