Freshwater Ecoregions of the World: A New Map of Biogeographic Units for Freshwater Biodiversity Conservation
Preliminary data for fish species compiled by ecoregion reveal some previously unrecognized areas of high biodiversity, highlighting the benefit of looking at the world's freshwaters through a new framework.
Identifying Canadian Freshwater Fishes through DNA Barcodes
The present study evidenced that freshwater fish species can be efficiently identified through the use of DNA barcoding, especially the species complex of small-sized species, and that the present COI library can be used for subsequent applications in ecology and systematics.
Conservation status of imperiled north American freshwater and diadromous fishes
This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989, and reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa.
Postglacial dispersal of freshwater fishes into Ontario
To understand the processes that resulted in the recolonization of Ontario by fishes following the last glacial period, the refugial areas occupied by each species were determined using aRefugial index, and glacial water bodies used as dispersal routes were identified.
Potential impacts of climate change on the distributions of several common and rare freshwater fishes in Canada
Climate change will ultimately affect the supply and quality of freshwater lakes and rivers throughout the world. This study examines the potential impacts of climate change on freshwater fish…
PREDICTING OCCURRENCES AND IMPACTS OF SMALLMOUTH BASS INTRODUCTIONS IN NORTH TEMPERATE LAKES
Smallmouth bass and other warmwater littoral piscivores are presently ex- panding their geographic range northward into lakes across southern Canada. Smallmouth bass introduction can dramatically…
Biogeographic patterns of fish species richness in Ontario lakes in relation to historical and environmental factors

The partial Mantel test indicated regional lake species richness was significantly correlated with postglacial dispersal and climate and principal coordinates analysis identified length of time since deglaciation, length of...
Comparative distribution and invasion risk of snakehead (Channidae) and Asian carp (Cyprinidae) species in North America
Snakehead and Asian carp distributions were correlated with thermal factors, whereas those of Asian carps were related mainly to precipitation, and the driving environmental variables for the two fish groups were compared.
Impacts of Alien Invasive Species on Freshwater Fauna at Risk in Canada
The threat factors contributing to the endangerment of freshwater fishes and molluscs in Canada are examined and the nature of alien invasive species introductions affecting aquatic species at risk is examined.
A Comparison of Methods for Sampling Fish Diversity in Shallow Offshore Waters of Large Rivers
Significantly higher fish species richness and abundance were obtained and more unique species were captured by seine nets than by any other gear type.
