Flycatcher song in allopatry and sympatry--convergence, divergence and reinforcement.
The theory of reinforcement predicts that natural selection against the production of unfit hybrids favours traits that increase assortative mating. Whether culturally inherited traits, such as bird song, can increase assortative mating by reinforcement is largely unknown. We compared songs of pied (Ficedula hypoleuca) and collared flycatchers (F. albicollis) from two hybrid zones of different ...

Convergence and Divergence in Standard and Averaging Reinforcement Learning
Although tabular reinforcement learning (RL) methods have been proved to converge to an optimal policy, the combination of particular conventional reinforcement learning techniques with function approximators can lead to divergence. In this paper we show why off-policy RL methods combined with linear function approximators can lead to divergence. Furthermore, we analyze two different types of u...
متن کاملDemographic Divergence History of Pied Flycatcher and Collared Flycatcher Inferred from Whole-Genome Re-sequencing Data
Profound knowledge of demographic history is a prerequisite for the understanding and inference of processes involved in the evolution of population differentiation and speciation. Together with new coalescent-based methods, the recent availability of genome-wide data enables investigation of differentiation and divergence processes at unprecedented depth. We combined two powerful approaches, f...
متن کاملSympatry, allopatry and sexual isolation between Drosophila mojavensis and D. arizonae.
Populations of the North American cactophilic fruitfly Drosophila mojavensis and its sibling species D. arizonae exist both in sympatry and in allopatry. Females of D. arizonae, regardless of their population of origin, are effectively completely isolated behaviorally from D. mojavensis males. On the other hand, females of D. mojavensis from the sympatric populations in Sonora, Mexico exhibit s...
