Low Genetic Connectivity of Strongly Inbred Ruppia brevipedunculata in Aquaculture Dominated Lagoons (Viet Nam)

Frontiers in Conservation Science, 2021
Lagoonal environments exhibit high levels of instability depending on hydrological, climatic and ecological factors, thereby influencing the distribution and structure of submerged plant communities.

Exploring the relationship between tychoparthenogenesis and inbreeding depression in the Desert Locust, Schistocerca gregaria [PDF]

, 2017
Tychoparthenogenesis, a form of asexual reproduction in which a small proportion of unfertilized eggs can hatch spontaneously, could be an intermediate evolutionary link in the transition from sexual to parthenogenetic reproduction.

How should we measure population-level inbreeding depression? Impacts of standing genetic associations between selfing rate and deleterious mutations

Frontiers in Plant Science
Inbreeding depression (ID) is a major selective force during mating system evolution primarily contributed by highly to partially recessive deleterious mutations.

Duration of pairing and use of allosperm in Biomphalaria glabrata (Gastropoda: Planorbidae) Duração do acasalamento e uso do aloesperma em Biomphalaria glabrata (Gastropode: Planorbidae)

Memorias do Instituto Oswaldo Cruz, 1989
Virgin homozygous black pigmented and albino Biomphalaria glabrata are paired during a period varying from 1 to 20 days. The rate of cross-fertilized parents is statistically similar for the various lengths of pairing.

Distribution of genetic diversity in wild European populations of prickly lettuce (Lactuca serriola): implications for plant genetic resources management [PDF]

, 2010
Genetic variation in Lactuca serriola, the closest wild relative of cultivated lettuce, was studied across Europe from the Czech Republic to the United Kingdom, using three molecular marker systems, simple sequence repeat (SSR, microsatellites), AFLP and

Evolutionary implications of a high selfing rate in the freshwater snail Lymnaea truncatula. [PDF]

, 2003
Self-compatible hermaphroditic organisms that mix self-fertilization and outcrossing are of great interest for investigating the evolution of mating systems.

Duodichogamy and androdioecy in the Chinese Phyllanthaceae Bridelia tomentosa [PDF]

, 2007
Flowering plants commonly separate male and female function in time, but rarely are the two stages synchronized within and among individuals. One such temporal mating system is duodichogamy in which each plant produces two batches of male flowers that ...

Inbreeding depression in crambe

Pesquisa Agropecuária Tropical, 2016
Inbreeding depression in plants, caused by selfing or crossing among plants with a high degree of relatedness, is a genetic phenomenon that affects quantitative traits.
