In addition, fire as a management tool may have unexpected and negative consequences for the breeding structures of populations (Gross et al., 2012) when the frequency and intensity are unnatural.
Besides the fundamental aspect of this finding, this work also has important consequences for the breeding strategies.
As a consequence, increasing age structure will, for a given deme size, reduce the part of the breeding population that has just reached adulthood and potentially migrated.
This study was aimed at estimating the genetic risk for AS in French sheep and potential consequences of the current breeding programme for the ARR allele on the risk of atypical scrapie.
Dr. Kraemer is devoted to bulldogs and sees the heartbreaking consequences of bad breeding every day in his veterinary clinic in Orange County, CA. As medical director for SoCal Bulldog Rescue (SCBR), Dr Kraemer houses, feeds, and provides medical treatment for up to 25 rescued Bulldogs at any given time.
Currently, programs implemented to support rapidly declining species have attempted to address the impact of human-altered environments on the evolutionary processes of species in captivity (Smith and Bernatchez 2007), but it is clear that more attention is needed to deal with the evolutionary consequences of captive breeding for conservation (Frankham 2008; Pelletier et al. 2009).
These results suggest that the directionality of threat calls provides important information about the auditory scene and spatial orientation of conspecifics and that this trait, along with the receiver's ability to extract this information, may have evolved as a consequence of its effect on the breeding success and fitness of the individual.
This paper examines the possible consequences of breeding on growth and gas exchange in P. radiata populations in Chile, by examining phenotypic variation in early growth and physiological performance of trees established on a drought-prone site.
Our second aim was to examine the fitness consequences of breeding with genetically similar or dissimilar individuals.
Another consequence of these breeding programs was the selection for specific traits that are characteristic of the fresh and processing markets which has led to further diversification and genetic differentiation among market classes.
