The taxonomic records presented here represent a conservative, morphology-based approach to identification that resulted in less taxonomic resolution than is commonly found in literature on Quaternary herpetofaunas, and it is hypothesised that the observed stability may be related to evolutionary adaptations (e.g. cold-tolerance) in specific lineages.
Anuran call surveys on small wetlands in Prince Edward Island, Canada restored by dredging of sediments
In 1990, the North American Waterfowl Management Plan (NAWMP) implemented a small-wetland restoration program in Prince Edward Island (PEI), Canada. Wetlands were restored by means of dredging
Anuran Development, Density and Diversity in Relation to Agricultural Activity in the Holland River Watershed, Ontario, Canada (1990–1992)
Nutrient run-off as a causal or contributing factor in lower anuran diversity, density and reproductive success of American toads and green frogs in the site dominated by agriculture is suggested.
Correlates of Waterbody Characteristics and the Occurrence or Diversity of Larval Amphibians in Central Ontario, Canada
Amphibians were present in some low-pH waterbodies, contrasting earlier studies, and generally water chemistry was not a strong indicator of amphibian presence or diversity in central Ontario.
Incidentally gathered natural history information on Bullsnakes (Pituophis catenifer sayi) in southeastern Alberta
We present observations on Bullsnakes (Pituophis catenifer sayi) gathered during a study of Prairie Rattlesnakes (Crotalus viridis) in a multiple-use, mixed grass landscape adjacent to the South
What Does the Snake Eat? Breadth, Overlap, and Non-Native Prey in the Diet of Three Sympatric Natricine Snakes
It is noteworthy that the two most abundant prey types, slugs and earthworms, are non-native and occur in high numbers, which may ameliorate competitive interactions and influence grassland snake abundance and persistence regionally.
The northward extension of reptiles in the Palearctic, with the Jordan Valley (Israel) as a model: snakes outrace lizards (Reptilia: Squamata)
ABSTRACT The geographical distribution of reptiles is known to be climate dependent. Our analysis of literature data from the Palearctic confirmed that snakes, as a group (186 species), tend to
Absence d’amphibiens dans la péninsule d’Ungava ?
Ces resultats ainsi que les autres sources d’informations consultees suggerent l’absence d‘amphibiens a la hauteur de l”aire d”etude” sont proposedes pour expliquer cette apparente absence.
