Forestry Management Practices and Populations of Breeding Birds in a Hardwood Forest in Nova-Scotia Canada
Effects of forestry practices on the breedig birds of a hardwood forest in Nova Scotia were studied. Total breeding density on 3 uncut control plots was (.times. .+-. SD) 663 .+-. 145 pairs/km2. Total breeding densities ...

Structural and functional connectivity of marine fishes within a semi-enclosed Newfoundland fjord
The interplay between structural connectivity (i.e. habitat continuity) and functional connectivity (i.e. dispersal probability) in marine fishes was examined in a coastal fjord (Holyrood Pond, Newfoundland, Canada) that ...
Evaluating SNP ascertainment bias and its impact on population assignment in Atlantic cod, Gadus morhua
The increasing use of single nucleotide polymorphisms (SNPs) in studies of nonmodel organisms accentuates the need to evaluate the influence of ascertainment bias on accurate ecological or evolutionary inference. Using a ...
Global patterns in marine dispersal estimates: the influence of geography, taxonomic category and life history
We examine estimates of dispersal in a broad range of marine species through an analysis of published values, and evaluate how well these values represent global patterns through a comparison with correlates of dispersal. ...
DNA barcoding of Canada's skates
DNA-based identifications have been employed across broad taxonomic ranges and provide an especially useful tool in cases where external identification may be problematic. This study explored the utility of DNA barcoding ...
Mixed evidence for reduced local adaptation in wild salmon resulting from interbreeding with escaped farmed salmon: complexities in hybrid fitness
Interbreeding between artificially-selected and wild organisms can have negative fitness consequences for the latter. In the Northwest Atlantic, farmed Atlantic salmon recurrently escape into the wild and enter rivers where ...
Non-linear genetic isolation by distance: implications for dispersal estimation in anadromous and marine fish populations
Indirect genetic approaches such as those based on the association between genetic and geographic distance (isolation by distance, IBD) may provide one of the best means of estimating dispersal in marine systems. We ...
Polymorphic microsatellite DNA markers in the mangrove crab Ucides cordatus (Brachyura: Ocypodidae)
The isolation and characterization of the first polymorphic microsatellite markers for the mangrove crab Ucides cordatus are described. The number of alleles at each locus ranged from three to 25, mean of nine alleles, in ...
Polymorphic tetranucleotide microsatellite markers in the Caribbean spiny lobster, Panulirus argus
Ten tetranucleotide microsatellite loci are described for the Caribbean spiny lobster Panulirus argus. Loci were polymorphic (4-15 alleles per locus) and exhibited high levels of expected (0.553-0.921) and observed ...
