Parallel evolution of similar traits in independent populations that inhabit ecologically similar environments strongly implicates natural selection as the cause of evolution. Parallel speciation is a special form of parallel evolution where traits that determine reproductive isolation evolve repeatedly, in closely related populations, as by-products of adaptation to ecological conditions. The outcome of such parallel evolution is that ecologically divergent pairs of populations exhibit greater… 
Divergent host-plant adaptation and the evolution of reproductive isolation
TLDR
Molecular and morphological evidence suggest that the hostassociated forms of T. cristinae are unlikely to have achieved species status such that thehost forms represent either an ongoing speciation event or population divergence that has reached equilibrium.
Natural selection and divergence in mate preference during speciation
TLDR
Understanding of the evolution of sexual isolation can be enhanced by isolating the roles of diverse ecological and evolutionary processes, and it is shown that sexual isolation involves, at least in part, olfactory communication.
Evidence for mutation-order speciation between convergent ecotypes
TLDR
A comprehensive test of the ecological speciation hypothesis in an Australian wildflower where parapatric populations found in coastal sand dunes and headlands have repeatedly and independently diverged in growth habit finds that both extrinsic and intrinsic reproductive isolation evolved between prostrate Headland populations.
Stick Insect Genomes Reveal Natural Selection’s Role in Parallel Speciation
Stick to the Bush Can the underlying genetic changes driving the divergence of populations into new species be predicted or repeated? Soria-Carrasco et al. (p. 738) investigated the genetic changes
PARALLEL EVOLUTION OF SEXUAL ISOLATION IN STICKLEBACKS
TLDR
This work investigates the roles of divergent natural and sexual selection in the evolution of sexual isolation between sympatric species of threespine sticklebacks and finds that sexual isolation arises in the same way: assortative mating on body size and asymmetric isolation due to male nuptial color.
PARALLEL EVOLUTION OF SEXUAL ISOLATION IN STICKLEBACKS
Abstract Mechanisms of speciation are not well understood, despite decades of study. Recent work has focused on how natural and sexual selection cause sexual isolation. Here, we investigate the roles
Evidence for mutation-order speciation in an Australian wildflower
TLDR
It is found that Dune populations with erect growth habit were easy to transplant across sand dunes, were largely interfertile despite half-a-million years of divergence, and were reproductively isolated from equally divergent Headland populations with prostrate growth habit.
Non-parallel morphological divergence following colonization of a new host plant
TLDR
This work uses a host shift in the phytophagous peacock fly Tephritis conura to investigate convergence in morphological adaptations and finds surprisingly low and variable divergence between host races.
Evidence for mutation-order speciation inSenecio lautus
TLDR
It is found that Dune populations with erect growth habit were easy to transplant across sand dunes, were largely interfertile despite half-a-million years of divergence, and were reproductively isolated from equally divergent Headland populations with prostrate growth habit.
PHYLOGENETIC EVIDENCE FOR MULTIPLE SYMPATRIC ECOLOGICAL DIVERSIFICATION IN A MARINE SNAIL
TLDR
This analysis provides strong evidence that divergent selection across a sharp ecological gradient promoted the parallel divergence of body size and shape between two sympatric ecotypes, which may represent the first step in speciation.

TLDR
A method for isolating and evaluating the contribution of host plant‐related natural selection pressures to the reproductive isolation between allopatric herbivore populations is offered.
Phylogenetic evidence for the evolution of ecological specialization in Timema walking‐sticks
TLDR
This analysis showed that host‐plant use has evolved nonrandomly, such that more closely related species tend to use similar sets of hosts and colour pattern evolution exhibits considerable lability, and that information from biogeography, floristic history and the timing of diversification of the genus are compatible with patterns of inferred ancestral host‐ plant use.
Parallel Speciation by Natural Selection
TLDR
The purpose here is to introduce an unappreciated form of evidence for natural selection that is defined as the repeated independent evolution of the same reproductive isolating mechanism, and to explain the phenomenon and list criteria needed to demonstrate it.
Genetic variation and reproductive isolation among phenotypically divergent amphipod populations
TLDR
Interbreeding results, considered together with between-ecotype differences in allele and genotype structure, suggest that Hyalella ecotypes in southeast Michigan form at least two separate species, and the lack of distinct allelic differences and the relative levels of allele frequency differentiation within and between ecotypes suggest recent local speciation in this taxon.
Natural selection and parallel speciation in sympatric sticklebacks.
TLDR
The post-Pleistocene radiation of threespine sticklebacks was used to infer natural selection in the origin of species, and speciation has proceeded in this adaptive radiation in a repeatable fashion.
Phylogenies for ecologists
TLDR
Whenever ecologists attempt to understand which traits or characteristics allow different taxa to be successful in different ecological circumstances, phylogenetic information should be incorporated into their analyses whether the data are experimental or observational.
The Dilemma of Plants: To Grow or Defend
TLDR
A conceptual model of the evolution of plant defense is concluded, in which plant physioligical trade-offs interact with the abiotic environment, competition and herbivory.

TLDR
Two morphs of the walking‐stick Timema cristinae were each strongly associated with patches of distinct species of food plants on which they are most cryptic, and result (3) is consistent with Levene's multiple‐niche polymorphism model.
Coexistence Mediated by Recruitment Fluctuations: A Field Guide to the Storage Effect
TLDR
The storage mechanism is capable of independently maintaining species coexistence, and some suggestions on how to distinguish qualitatively the operation of storage from alternative mechanisms are provided.
Dynamics of metapopulations : habitat destruction and competitive coexistence
TLDR
The present study suggests that patch removal can by itself favour 'weedy' species, even in the absence of other, concomitant changes.
