Ecology and Evolution, 2020 Disentangling the strength and importance of barriers to reproduction that arise between diverging lineages is central to our understanding of species origin and maintenance. To date, the vast majority of studies investigating the importance of different

The existence of species rests on a metastable equilibrium between inbreeding and outbreeding [PDF]
, 2011 Background: Speciation corresponds to the progressive establishment of reproductive barriers between groups of individuals derived from an ancestral stock.

Wolbachia-induced reproductive isolation [PDF]
Genome Biology, 2001 Infection with the bacterium Wolbachia is sufficient to establish a reproductive barrier between two otherwise compatible species of wasp, making Wolbachia a potential driving force in evolution.

HYBRID ZONES AND REPRODUCTIVE ISOLATION [PDF]
Evolution, 1965 The interpretation of hybrid zones remains one of the most difficult of taxonomic problems, despite the striking advances in systematics of recent decades. Mayr (1963: 496) selected sexual isolation, hybrid fertility, and developmental compatibility as the only criteria that will render possible unequivocal decisions (one species or two) in the case of

Territorial exclusion and reproductive isolation [PDF]
Psychonomic Science, 1972 Three experiments demonstrate that Mongolian gerbils exclude intruders from home territories and force them to migrate across a water barrier. Of those animals that did migrate in the third experiment, the majority avoided olfactory cues from the territory from which they were excluded.

A Novel Combination of Genes Causing Temperature-Sensitive Hybrid Weakness in Rice
Frontiers in Plant Science, 2022 Reproductive isolation is an obstacle for plant breeding when a distant cross is demanded. It can be divided into two main types based on different growth stages: prezygotic isolation and postzygotic isolation.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Courtship plasticity reveals the evolution of dialects in allopatric fish populations [PDF]
, 2008 Traditionally, reproductive isolation between disjoint populations has been thought to emerge as a result of the accumulation of different mutations, genetic drift, or through the effects of natural and sexual selection^1^.

Do highly divergent loci reside in genomic regions affecting reproductive isolation? A test using next-generation sequence data in Timema stick insects [PDF]
, 2012 Background: Genetic divergence during speciation with gene flow is heterogeneous across the genome, with some regions exhibiting stronger differentiation than others.
