Interspecific competition, hybridization, and reproductive isolation in secondary contact: missing perspectives on males and females
Research on sexual selection and hybridization has focused on female mate choice and male-male competition. While the evolutionary outcomes of interspecific female preference have been well explored, we are now gaining a better understanding of the processes by which male-male competition between species in secondary contact promotes reproductive isolation versus hybridization. What is relative...

متن کاملThe ecological and evolutionary stability of interspecific territoriality.
Interspecific territoriality may play an important role in structuring ecological communities, but the causes of this widespread form of interference competition remain poorly understood. Here, we investigate the phenotypic, ecological and phylogenetic correlates of interspecific territoriality in wood warblers (Parulidae). Interspecifically territorial species have more recent common ancestors...
متن کاملProduction of genetically male tilapia through interspecific hybridization between Oreochromis niloticus and O. aureus
This study was conducted to produce a high percentage of genetically male tilapia through interspecific hybridization between Nile tilapia, Oreochromis niloticus and Blue tilapia, O. aureus and evaluate sex ratio, productive performance and heterosis of the progeny produced. The results revealed that sex ratios of the progenies of (♀ O. aureus x ♂ O. niloticus) and (♀ O. niloticus x ♂ O. aureus...
متن کاملInterspecific brood parasitism in galliform birds
Mode of development in birds helps determine the form of brood parasitism a species exhibits. Most knowledge of precocial brood parasites comes from a single avian family, the waterfowl (Anatidae: Anseriformes). Here we review cases of interspecific brood parasitism (IBP) in a second group of precocial birds, the order Galliformes. IBP is uncommon but taxonomically widespread, occurring in at l...
