Reproductive isolation between two populations of Aglaoctenus lagotis , a funnel-web wolf spider [PDF]

, 2015
Aglaoctenus lagotis (Lycosidae: Sosippinae) is a spider that, in contrast to the predominant wandering habit of the family, constructs funnel webs.

THE EVOLUTION OF STRONG REPRODUCTIVE ISOLATION [PDF]

Evolution, 2009
Felsenstein distinguished two ways by which selection can directly strengthen isolation. First, a modifier that strengthens prezygotic isolation can be favored everywhere. This fits with the traditional view of reinforcement as an adaptation to reduce deleterious hybridization by strengthening assortative mating. Second, selection can favor association

Potential inbreeding in a small population of a mass flowering species, Xanthorrhoea johnsonii (Xanthorrhoaceae): is your mother my father? [PDF]

, 2012
Xanthorrhoea johnsonii is a long lived slow growing perennial understorey species, that produces a large quantity of passively dispersed seed every 3-5 years. Reproductive maturity is not reached until 20-30 years of age.

Genetic Variability of the Mating Recognition Gene in Populations of Brachionus plicatilis

Diversity, 2022
The development of reproductive barriers promotes within-species divergence and is a requisite for speciation to occur. Mate recognition in the rotifer B. plicatilis is mediated through a surface glycoprotein called Mating Recognition Protein (MRP). Here

An introgressed wing pattern acts as a mating cue. [PDF]

, 2015
Heliconius butterflies provide good examples of both homoploid hybrid speciation and ecological speciation. In particular, examples of adaptive introgression have been detected among the subspecies of Heliconius timareta, which acquired red color pattern

Co-evolution of male and female reproductive traits across the Bruchidae (Coleoptera) [PDF]

, 2008
1. Despite the obvious importance of spermatozoa to individual reproductive success a general explanation of variation in spermatozoan form and function is still lacking. In species with internal fertilization, sperm not only have to interact with the

Asymmetric reproductive isolation between two sympatric annual killifish with extremely short lifespans. [PDF]

PLoS ONE, 2011
BACKGROUND: Interspecific reproductive isolation is typically achieved by a combination of intrinsic and extrinsic barriers. Behavioural isolating barriers between sympatric, closely related species are often of primary importance and frequently aided by

Neo-Allopatry and Rapid Reproductive Isolation

The American Naturalist, 2012
Over the past 3 centuries, many species have been dispersed beyond their natural geographic limits by humans, but to our knowledge, reproductive isolation has not been demonstrated for such neo-allopatric species. We grew seeds from three species of Centaurea (Centaurea solstitialis, Centaurea calcitrapa, and Centaurea sulphurea) that are native to ...

Prepollination barriers prevent gene flow between co-occurring bat-pollinated bromeliads in a montane forest [PDF]

PeerJ
Background Reproductive isolation mechanisms in flowering plants are fundamental to preserving species’ evolutionary independence and to enabling the local coexistence of closely related species.
