Document Summary
Species in blue: shown recent declines in population, although both seem to be rebounding well. Alberta: boreal forest in northern half (bit of canadian shield), grasslands in southeast, parkland in between, foothills/mountains along the western wiggly-line border. Since reptiles and amphibians do well in warmer places, most diverse in the grasslands. Especially south east, away from the mountains near calgary & south. Good diggers, burrowers, lives away from water but develop from aquatic larvae. Common to find in basements, sprinkler control boxes. In many cases, the larvae develops in not good places to become land-dwellers (fail to metamorphose) and become sexually mature while retaining their larval gills. Neotenic adult: staying in larvae form but matured sexually (happens in dry lands), retains larval gills. Axolotls usually name restricted to a related species in mexico. Extirpated in the wild but common as pets. Alberta neotenic tiger salamanders can be found in isolated water bodies. Smaller, yellowish blob streak down the back (middorsal)
