Ecological disruptive selection acting on quantitative loci can drive sympatric speciation
The process of speciation generates biodiversity. According to the null model of speciation, barriers between populations arise in allopatry, where,...

Exceptional Genetic Differentiation at a Micro-geographic Scale in Apistogramma agassizii (Steindachner, 1875) from the Peruvian Amazon: Sympatric Speciation?
Mechanisms related to ecological or sexual selection have favoured sympatric speciation events in African and Central American lake cichlids....

The emergence of ecotypes in a parasitoid wasp: a case of incipient sympatric speciation in Hymenoptera?
BackgroundTo understand which reproductive barriers initiate speciation is a major question in evolutionary research. Despite their high species...

Patterns and Processes of Speciation in Lymnaeidae
In the present chapter, we aimed to summarize the current knowledge of patterns and processes of speciation in the gastropod family Lymnaeidae. Using...

Analysis of the speciation process suggests a dual lifestyle in the plant pathogen Ralstonia solanacearum species complex
Ralstonia solanacearum species complex (RSSC) is the causal agent of bacterial wilt disease in many plant species, including important crops. It is...

The Evolution of Redfishes of the Genus Sebastes (Perciformes: Sebastidae) of the Atlantic and Arctic Oceans: Budding Speciation in a Species Flock
AbstractThe evolutionary history of North Atlantic Sebastes redfishes was reconstructed as a result of studying the mitochondrial DNA D-loop...

Lack of genetic differentiation between two sympatric lacustrine morpho-species within the Astyanax (Characidae: Teleostei) genus, Mexico
We analyzed two morpho-species, Astyanax aeneus and Astyanax caballeroi , coexisting in Lake Catemaco, with ecological differences previously...

Polyploid speciation in Zea (Poaceae): cytogenetic insights
Main conclusionThe analysis of meiotic pairing affinities and genomic formulae in species and hybrids of Zea allowed us to speculate an evolutionary...

Evolutionary characteristics of the mitochondrial NADH dehydrogenase subunit 6 gene in some populations of four sympatric Mustela species (Mustelidae, Mammalia) from central Europe
BackgroundSelection on or reticulate evolution of mtDNA is documented in various mammalian taxa and could lead to misleading phylogenetic conclusions...

Diversity-dependent speciation and extinction in hominins
The search for drivers of hominin speciation and extinction has tended to focus on the impact of climate change. Far less attention has been paid to...

Evaluating the macro and micro geographic mechanisms that modulate the coexistence between sympatric Sturnira bat species
One of the key questions in ecology is to understand the mechanisms that modulate the coexistence between sympatric species. Climate and habitat...

Speciation
Most gall-inducing cecidomyiids are associated closely with particular plant taxa. Many examples of species radiation on a single or a few plant...

Between allopatry and secondary contact: differentiation and hybridization among three sympatric Gentiana species in the Qinghai-Tibet Plateau
BackgroundMountains of the world host a significant portion of all terrestrial biodiversity, and the region of the Qinghai-Tibet Plateau (QTP) stands...

Mosaic Evolution of Gras** and Genital Traits in Two Sympatric Scorpion Species with Reproductive Interference
Components of the same structure or characters of the same individual might respond differently to natural and sexual selective pressures, showing...
-
Geographic isolation drives speciation in Nearctic aphids
Across herbivorous insect clades, species richness and host-use diversity tend to positively covary. This could be because host-use divergence drives...

Speciation Processes in Triatominae
This chapter intends to familiarize the reader with the basic concepts regarding speciation in insects, through the description and exemplification...

How do the sympatric forest mongooses coexist in the Western Ghats landscape? Insights from spatio-temporal approach
Interactions shape the existence, abundance, and dynamics of species in an ecological community. Using ecological niche modelling and temporal...

Exploring mycorrhizal diversity in sympatric mycoheterotrophic plants: a comparative study of Monotropastrum humile var. humile and M. humile var. glaberrimum
Mycoheterotrophic plants (MHPs) rely on their mycorrhizal fungus for carbon and nutrient supply, thus a shift in mycobionts may play a crucial role...
-
Species and Speciation
In the context of the dynamical systems approach, species are of central importance as quantities of living matter with defined structural and...

Pollinator sharing, copollination, and speciation by host shifting among six closely related dioecious fig species
The obligate pollination mutualism between figs ( Ficus , Moraceae) and pollinator wasps (Agaonidae, Hymenoptera) is a classic example of cospeciation....
