Sexual selection drives asymmetric introgression in wall lizards.
Hybridisation is increasingly recognised as an important cause of diversification and adaptation. Here, we show how divergence in male secondary sexual characters between two lineages of the common wall lizard (Podarcis muralis) gives rise to strong asymmetries in male competitive ability and mating success, resulting in asymmetric hybridisation upon secondary contact. Combined with no negative...
متن کاملGenetic drift or natural selection? Hybridization and asymmetric mitochondrial introgression in two Caribbean lizards (Anolis pulchellus and Anolis krugi).
Hybridization and gene introgression can occur frequently between closely related taxa, but appear to be rare phenomena among members of the species-rich West Indian radiation of Anolis lizards. We investigated the pattern and possible mechanism of introgression between two sister species from Puerto Rico, Anolis pulchellus and Anolis krugi, using mitochondrial (ND2) and nuclear (DNAH3, NKTR) D...
متن کاملWhy Nearshore Drives Competition
As the outsourcing and offshoring phenomena have matured, the marketplace has sought increased differentiation on the basis of location through a range of ‘shoring’ and ‘sourcing’ terms. “Rural-sourcing,” “two-shoring,” “best-shoring,” and at least a dozen other expressions have emerged. Prominent among these is “nearshore,” which appeared in the software/IT field first in an article about an e...
متن کاملSexual Selection in the Water Spider: Female Choice and MaleMale Competition
When selection acts differently on the body size of males and females, their adult sizes may diverge. The resulting sexual size dimorphism (SSD) covers an astounding range across taxa, with extreme examples in both directions (see Fairbairn et al. 2007). Generally, in most sexually reproducing animals, females are the larger sex (Andersson 1994; Fairbairn et al. 2007), which is mainly explained...
متن کاملArousal-Biased Competition in Perception and Memory.
Our everyday surroundings besiege us with information. The battle is for a share of our limited attention and memory, with the brain selecting the winners and discarding the losers. Previous research shows that both bottom-up and top-down factors bias competition in favor of high priority stimuli. We propose that arousal during an event increases this bias both in perception and in long-term me...
