Inbreeding coefficients and coalescence times

Genetics Research, 1991
SummaryThis paper describes the relationship between probabilities of identity by descent and the distribution of coalescence times. By using the relationship between coalescence times and identity probabilities, it is possible to extend existing results for inbreeding coefficients in regular systems of mating to find the distribution of coalescence ...

Waves of range dynamics and gene flow characterize the biogeographic history of Litsea elongata, a dominant tree in East Asian evergreen broadleaved forests

PLANTS, PEOPLE, PLANET, EarlyView.
Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it

Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

PLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

Analysis of resistance against white spot syndrome virus infection in Fenneropenaeus chinensis considering different inbreeding coefficients

Aquaculture Reports, 2023
The relationship between inbreeding and traits of disease resistance in shrimp has not been studied comprehensively. To explore the effect of inbreeding on white spot syndrome virus (WSSV) resistance in Fenneropenaeus chinensis, we established F ...

Inbreeding Depression in Two Mimulus Taxa Measured by Multigenerational Changes in the Inbreeding Coefficient [PDF]

Evolution, 1993
In mixed-mating plant populations, one can estimate the relative fitness of selfed progeny w by measuring the inbreeding coefficient F and selfing rate s of adults of one generation, together with F of adults in the following generation (after selection).

Water depth and human disturbance drive occupancy of endangered softshell turtles (Nilssonia spp.) in eastern Nepal

Wildlife Biology, EarlyView.
Freshwater turtles play vital roles in maintaining the health of aquatic ecosystems by supporting ecological balance, nutrient cycling and regulating prey populations. Unfortunately, they are among the most threatened species worldwide. Habitat fragmentation, illegal trade, overharvesting for meat, and use in ethnomedicinal practices have severely ...

Inbreeding and fertility in Irish Wolfhounds in Sweden: 1976 to 2007

Acta Veterinaria Scandinavica, 2009
Background Given that no influence of inbreeding on life expectancy could be demonstrated in Irish Wolfhounds in a previous study, it was decided to test the influence of inbreeding and other parameters on fertility in this breed.

Population structure and inbreeding of Holstein cattle in southern Brazil

Revista Brasileira de Zootecnia, 2020
The present investigation aimed to evaluate the population structure and inbreeding of Holstein herds in southern Brazil. To carry out the analysis, the Associação Paranaense de Criadores de Bovinos da Raça Holandesa (APCBRH) in Brazil provided the data,

Genetic population structure of red foxes Vulpes vulpes across a rural landscape: insights into population connectivity and spatial patterns

Wildlife Biology, EarlyView.
Human activities have shaped and are continuing to influence terrestrial landscapes, creating heterogenous, and often, fragmented landscapes. Generalist species, like the red fox Vulpes vulpes, show high flexibility in habitat use, and occur across the heterogeneous, anthropogenic landscapes of central Europe.

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

Wildlife Monographs, EarlyView.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low
