Thus, the functional and genetic difference between cultivar and local ecotypes of prairie grasses provides a novel context to investigate whether intraspecific variation in genetic stock (seed source) differentially affects ecosystem functioning during ecological restoration.
Instead of going on location to shoot original material, as he did for the first two films, Mr. Reggio plans to create a visual symphony of existent footage, gleaned from a multitude of stock sources.
A total of 820 gilts were included in the study, which were commercial breeding stock sourced from Newsham Choice Genetics (West Des Moines, IA, USA) between October 2005 and July 2006.
Boars were obtained from two Midwest USA breeding stock sources documented to be free of PRRSV infection.
Farm profiles, including stock sources, farm management, and biosecurity measures, were collected from 16 case and 46 control chicken farms by using a pretested questionnaire and personal interviews.
Key topics covered in the interviews included types of ITNs normally in stock, sources and challenges around delivery mechanisms; perceptions on affordability and acceptability of ITNs in the community they served, the role of the mass campaigns in improving coverage and perceptions around the strengths and weaknesses of the campaigns.
Indeed, most of the stocked lakes were highly admixed with their stocking source(s) and most of the individuals were assigned to nonlocal clusters or to the admixed category, while a smaller proportion of trout were assigned to the local cluster.
Participants or their employers may hold positions in these stocks Source: FT Interactive Data via FactSet Research Systems.
Specifically, captive stocks (source) contribute breeders to the wild (sink) each year, where reproductive success and recruitment are highly variable.
