Spatial structure and inbreeding depression in slickspot peppergrass, Lepidium papilliferum (Brassicaceae)

Importance of Outcrossing for Fruit Production in Slickspot Peppergrass, <em>Lepidium Papilliferum</em> L. (Brassicaceae)

Distance between pollen donor and recipient influences fruiting success in slickspot peppergrass, Lepidium papilliferum

Plant populations are often spatially structured owing to limited dispersal of pollen and seed. Mating between neighboring individuals in such populations often leads to reduced reproductive performance relative to matings between distant individuals. This response, which may be a result of inbreeding depression or prezygotic mating barriers, was investigated for slickspot peppergrass, Lepidium...

New Lepidium (Brassicaceae) from New Zealand

A revision of the New Zealand endemic Lepidium oleraceum and allied species is presented. Sixteen species are recognised, 10 of these are new. The new species are segregated on the basis of morphological characters supported by molecular data obtained from three DNA markers (two rDNA and one cpDNA). One species, Lepidium castellanum sp. nov., is endemic to the Kermadec Islands where it is sympa...

Inbreeding depression and partitioning of genetic load in the invasive biennial Alliaria petiolata (Brassicaceae).

UNLABELLED PREMISE OF THE STUDY Invasive species are nonnative species that enter novel environments, establish sustained populations, and can negatively impact native species. Here we assess a potential weakness of invasive species (genetic load) and show how species might overcome genetic barriers. Colonization of novel habitats by invasive species typically involves few individuals, expos...

Inbreeding and Inbreeding Depression on Body Weight in Iranian Shal Sheep

The aim of this study was to estimate amount of inbreeding coefficient in Shal sheep and its impact on growth performance. Pedigree information and body weight at different ages (birth weight, 3 month weight, 6 month weight, 9 month weight and 12 month weight) were used from 6692 lambs from 90 rams and 1007 ewes. Data were collected on Ghazvin sheep breeding station during 1997-2013. Estimation...
