Inbreeding depression in Solanum carolinense (Solanaceae), a species with a plastic self-incompatibility response

BMC Evolutionary Biology, 2008
Background Solanum carolinense (horsenettle) is a highly successful weed with a gametophytic self-incompatibility (SI) system. Previous studies reveal that the strength of SI in S. carolinense is a plastic trait, associated with particular S-alleles. The

SLC7A6OS Founder Mutation: A Rare Cause of Progressive Myoclonus Epilepsy Dated to 1100 Years Ago

Movement Disorders, EarlyView.
Abstract Background SLC7A6OS c.191A>G is a rare, autosomal recessive cause of progressive myoclonus epilepsy (PME). The c.191A>G variant, first discovered in two families from Türkiye and Portugal, was recently identified in three additional probands from the USA, all of Puerto Rican ancestry.

Male Assistance in Parental Care Does Not Buffer Against Detrimental Effects of Maternal Inbreeding on Offspring

Frontiers in Ecology and Evolution, 2018
The severity of inbreeding depression often varies across environments and recent work suggests that social interactions can aggravate or reduce inbreeding depression.

Perspectives and behaviors surrounding planting practices in North America inform genetic conservation realities for American ginseng (Panax quinquefolius)

PLANTS, PEOPLE, PLANET, EarlyView.
American ginseng is a shade‐obligate, North American medicinal plant that is widely traded and used internationally. To meet global demand, ginseng is cultivated in forest farms in the Appalachian region of the USA and field‐based artificial shade farms in two regions: Ontario, Canada and Wisconsin, USA. We conducted social research leveraging in‐depth

Analysis of Levels of Inbreeding and Inbreeding Depression in Jersey Cattle

Journal of Dairy Science, 1992
A pedigree file of 157,015 male and female Jersey cattle (born after 1955) from the Canadian herdbooks was investigated for the occurrence of inbreeding. A large proportion of Jersey bulls and cows were inbred (32.4 and 36.3% for bulls and cows, respectively). However, average inbreeding coefficients of these inbred cows and of all cows were low. First

Assessing genetic diversity in a reintroduced Mediterranean griffon vulture Gyps fulvus population to inform long‐term conservation management

Wildlife Biology, EarlyView.
Reintroductions play a key role in conservation biology. Their long‐term success strongly depends on maximizing the genetic diversity of founders, as well as on ensuring ecological connectivity with adjacent populations. Accordingly, evaluating the conservation status of reintroduced populations to limit the loss of their genetic diversity requires ...

Effect of recent and ancient inbreeding on production and fertility traits in Canadian Holsteins

BMC Genomics, 2020
Background Phenotypic performances of livestock animals decline with increasing levels of inbreeding, however, the noticeable decline known as inbreeding depression, may not be due only to the total level of inbreeding, but rather could be distinctly ...

Inbreeding depression in a parasitoid wasp with single-locus complementary sex determination. [PDF]

PLoS ONE, 2014
Inbreeding and inbreeding depression are key processes in small or isolated populations and are therefore central concerns for the management of threatened or (re)introduced organisms.

Biology, ecology, and conservation of the Italian hare Lepus corsicanus: a review

Wildlife Biology, EarlyView.
The Italian hare Lepus corsicanus, an endemic lagomorph of Italy, serves as a critical case study in evolutionary biology and conservation. Once taxonomically debated, modern genetic and morphological analyses confirm its status as a distinct Pleistocene lineage restricted to the central‐southern Italian Peninsula and Sicily.
