Sympatric speciation in parasites – what is sympatry? [PDF]

Trends in Parasitology, 2003
Parasites account for a large part of known species diversity and are considered to have a high potential for sympatric speciation. However, the frequency of sympatric divergence in these organisms will depend on the definition of sympatry that one uses.

Predicting distributions of Wolbachia strains through host ecological contact—Who's manipulating whom?

Ecology and Evolution, 2022
Reproductive isolation in response to divergent selection is often mediated via third‐party interactions. Under these conditions, speciation is inextricably linked to ecological context. We present a novel framework for understanding arthropod speciation

Genomic analyses of giant kelp reveal restricted connectivity across the Southern Hemisphere and striking diversity in Aotearoa (New Zealand)

Journal of Phycology, EarlyView.
Abstract The macroalga Macrocystis pyrifera (“giant” or “bladder” kelp) plays a vital role in cold‐temperate marine ecosystems but faces increasing threats from ongoing environmental change. Understanding its population diversity and connectivity is essential for predicting future range shifts and assessing the ecological consequences of such shifts in

The smelly path to sympatric speciation? [PDF]

Molecular Ecology, 2018
AbstractIn this issue of Molecular Ecology, Poelstra et al. () use genomic data to show that cichlid species in the adaptive radiation in Lake Ejagham, Cameroon, experienced gene flow with a riverine relative, primarily prior to their diversification. Intriguingly, this introgression brought with it olfactory alleles that the authors suggest may play a

Genetic linkage of distinct adaptive traits in sympatrically speciating crater lake cichlid fish

Nature Communications, 2016
Genetic linkage of ecologically relevant traits has been suggested to facilitate sympatric speciation. Here, Fruciano et al. show in sister species of cichlid fish the genetic non-independence of genomic regions responsible for differentiation in body ...

Crowd-sourced observations of a polyphagous moth reveal evidence of allochronic speciation varying along a latitudinal gradient.

PLoS ONE, 2023
Allochronic speciation, where reproductive isolation between populations of a species is facilitated by a difference in reproductive timing, depends on abiotic factors such as seasonality and biotic factors such as diapause intensity.

Integrative revision of the Australian carrion‐breeding Calliphorinae (Diptera: Calliphoridae): Revision of the Calliphora stygia‐ and ochracea‐groups

Medical and Veterinary Entomology, EarlyView.
The Australian carrion‐breeding Calliphorinae are revised using an integrative approach combining morphology and mitogenomics. A new taxonomic key, morphological images and verified mitogenomic data, including COX1 barcodes, are provided to support the identification of species.

A Crazy Idea: Ibn Sīnā on Hylomorphism, the Elements, Mixture and Evolutionary Processes

Theoria, EarlyView.
ABSTRACT Ibn Sīnā (c. 973‐1037), the Avicenna of Latin fame, developed a unique theory of the elements and their status in mixtures that severely challenged the views of earlier natural philosophers and in its turn was severely challenged by later Latin Schoolmen in the West.

Felsenstein's“one-allele model”of speciation: The role of philopatry in the initial stages of host plant mediated reproductive isolation in Enchenopa binotata

Current Zoology, 2013
The study of speciation genetics is primarily concerned with identifying the genetic traits that allow divergent selection to overcome the homogenizing effects of gene flow.

Through Time and Across Traits: Evaluating Explanations of Human Evolution

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 3, September 2026.
ABSTRACT We argue that current explanatory practice misses two situations that can arise in any lineage, not only ours. The first is dynamic: traits continue changing in one direction when a lineage's own niche construction keeps enlarging the problem it faces.
