Litter decay controlled by temperature, not soil properties, affecting future soil carbonNARA Subscribed
Widespread global changes, including rising atmospheric CO 2 concentrations, climate warming and loss of biodiversity, are predicted for this century; all of these will affect terrestrial ecosystem processes like plant litter decomposition. Conversely, increased plant litter decomposition can have potential carbon‐cycle feedbacks on atmospheric CO 2 levels, climate warming and biodiversity. But predicting litter decomposition...
Migration‐related phenotypic divergence is associated with epigenetic modifications in rainbow troutNARA Subscribed
Migration is essential for the reproduction and survival of many animals, yet little is understood about its underlying molecular mechanisms. We used the salmonid Oncorhynchus mykiss to gain mechanistic insight into smoltification, which is a morphological, physiological and behavioural transition undertaken by juveniles in preparation for seaward migration. O. mykiss is experimentally tractable and displays intra‐ and interpo...
This data set includes genotypes for 5000 chinook salmon individuals collected from throughout California's Central Valley between 1998 and 2013. We genotyped these samples using a panel of 96 single nucleotide polymorphism (SNP) markers. This is the most comprehensive genetic characterization published to date, covering all of the California Central Valley Evolutionary Significant Units (ESUs) and including all major river dr...
Exposure to contaminants can affect survivorship, recruitment, reproductive success, mutation rates and migration, and may play a significant role in the partitioning of genetic variation among exposed and nonexposed populations. However, the application of molecular population genetic data to evaluate such influences has been uncommon and often flawed. We tested whether patterns of genetic variation among native fish populati...
We present an algorithm to partition a single generation of individuals into full‐sib families using single‐locus co‐dominant marker data. Pairwise likelihood ratios are used to create a graph that represents the full‐sib relationships within the data set. Connected‐component and minimum‐cut algorithms from the graph theory are then employed to find the full‐sib families within the graph. The results of a large‐scale simulatio...
