Matching Habitat Choice Causes Directed Gene Flow: A Neglected Dimension in Evolution and Ecology
TLDR
The potential implications of matching habitat choice for the degree and rate of local adaptation, the evolution of niche width, adaptive peak shifts, speciation in the presence of gene flow, and on the view and interpretation of measures of natural selection are discussed.
Non-random gene flow: an underappreciated force in evolution and ecology.
TLDR
There is an urgent need for the fields of evolution and ecology to test for non-random gene flow and to more fully incorporate its effects into theory.
On the Origin of Species by Natural and Sexual Selection
TLDR
It is demonstrated that disruptive ecological selection favors the evolution of sexual preferences for ornaments that signal local adaptation, and thus natural and sexual selection work in concert to achieve local adaptation and reproductive isolation, even in the presence of substantial gene flow.
Comparisons between QST and FST—how wrong have we been?
TLDR
It is concluded that marker mutation rate indeed has had a biasing effect on published QST–FST comparisons, and it is no longer clear that populations have commonly diverged in response to divergent selection.
Explicit experimental evidence for the role of mate guarding in minimizing loss of paternity in the Seychelles warbler
TLDR
The Seychelles warbler is the first species to offer explicit experimental evidence that mate guarding functions as paternity guarding: in territories where free–living males were induced to stop mate guarding during the pair female's fertile period, the rates of intrusions by other males and successful EPCs were significantly higher than those observed in the control group.
Behaviour‐related DRD4 polymorphisms in invasive bird populations
TLDR
This work sequenced a candidate region for neophilic/neophobic and activity behaviour – the complete exon 3 of the DRD4 gene – in 100 Yellow‐crowned bishops from two invasive populations in Spain and Portugal and identified two synonymous DRD 4 SNPs that explained on average between 11% and 15% of the phenotypic variance in both populations.
Adaptive speciation theory: a conceptual review
TLDR
It is demonstrated that disruptive selection on both ecological and mating strategies is necessary, but not sufficient, for speciation to occur, and an integrative perspective is needed to achieve a thorough and coherent understanding of adaptive speciation.
Should I Change or Should I Go? Phenotypic Plasticity and Matching Habitat Choice in the Adaptation to Environmental Heterogeneity
TLDR
This work assessed which solutions evolved depending on degree of temporal variation, costs of multiple underlying traits, and order of dispersal and development to explain the apparent relative rarity of matching habitat choice in nature.
Hybridization due to changing species distributions: adding problems or solutions to conservation of biodiversity during global change?
TLDR
It is suggested that hybridization adds problems (loss of biodiversity, ecosystem degradation) as well as solutions (new adaptive variation, ecosystem robustness) to global change challenges.
Tonic immobility is a measure of boldness toward predators: an application of Bayesian structural equation modeling
TLDR
Individual variation in TI in a wild vertebrate can be interpreted in a context of boldness toward predators, making TI a meaningful and practical behavioral trait for studies involving personality and antipredation behavior in wild populations.
