Abstract: PREMISE Joshua trees (Yucca brevifolia and Y. jaegeriana) and their yucca moth pollinators (Tegeticula synthetica and T. antithetica) are a model system for studies of plant-pollinator coevolution and, they are thought to be one of… read more here.

Incomplete reproductive isolation and low genetic differentiation despite floral divergence across varying geographic scales in Castilleja.

DOI: 10.1002/ajb2.1700
Abstract: PREMISE Divergence depends on the strength of selection and frequency of gene flow between taxa, while reproductive isolation relies on mating barriers and geographic distance. Less is known about how these processes interact at early… read more here.

DOI: 10.1002/ajb2.1782
Abstract: PREMISE OF THE STUDY Habitat fragmentation generates molecular genetic divergence among isolated populations but few studies have assessed phenotypic divergence and fitness in populations where the genetic consequences of habitat fragmentation are known. Phenotypic divergence… read more here.

Phenotypic divergence in an island bee population: Applying geometric morphometrics to discriminate population‐level variation in wing venation

DOI: 10.1002/ece3.10085
Abstract: Abstract Phenotypic divergence is an important consequence of restricted gene flow in insular populations. This divergence can be challenging to detect when it occurs through subtle shifts in morphological traits, particularly in traits with complex… read more here.

Environmental correlates of geographic divergence in a phenotypic trait: A case study using bat echolocation

DOI: 10.1002/ece3.3251
Abstract: Abstract Divergence in phenotypic traits may arise from the interaction of different evolutionary forces, including different kinds of selection (e.g., ecological), genetic drift, and phenotypic plasticity. Sensory systems play an important role in survival and… read more here.

Drift versus selection as drivers of phenotypic divergence at small spatial scales: The case of Belgjarskógur threespine stickleback
Sign Up to like & getrecommendations! Published in 2019 at "Ecology and Evolution"
DOI: 10.1002/ece3.5381
Abstract: Abstract Divergence in phenotypic traits is facilitated by a combination of natural selection, phenotypic plasticity, gene flow, and genetic drift, whereby the role of drift is expected to be particularly important in small and isolated… read more here.

DOI: 10.1002/ece3.6007
Abstract: Abstract Pikas (Ochotona Link, 1795) are high‐altitude specialist species making them a useful bioindicator species to warming in high‐altitude ecosystem. The Himalayan Mountains are an important part of their range, supporting approximately 23%–25% of total… read more here.

DOI: 10.1002/ece3.6200
Abstract: Abstract Isolation by spatial distance (IBD), environment (IBE), and historical climatic instability (IBI) are three common processes assessed in phylogeographic and/or landscape genetic studies. However, the relative contributions of these three processes with respect to… read more here.

Migration‐tracking integrated phylogeography supports long‐distance dispersal‐driven divergence for a migratory bird species in the Japanese archipelago

DOI: 10.1002/ece3.7387
Abstract: Abstract Long‐distance dispersal (LDD) outside a species' breeding range contributes to genetic divergence. Previous phylogeographic studies of migratory bird species have not discriminated LDD from vicariant speciation in their diversification process. We conducted an integrative… read more here.

Abstract: Abstract The saltmarsh sparrow Ammospiza caudacuta and Nelson's sparrow A. nelsoni differ in ecological niche, mating behavior, and plumage, but they hybridize where their breeding distributions overlap. In this advanced hybrid zone, past interbreeding and… read more here.
