[Objectives] One specimen of Tropidophorus was collected from Yamugou Scenic Area, Jiangkou County, Guizhou Province during filed work in August 2019 and one specimen of Calotes was collected from Pandu Township, Lianjiang County, Fujian Provence in October 2019. [Methods] In order to identify these species, we conducted a morphological study on th...

Chemical self-recognition in Liolaemus pacha (Iguania: Liolaemidae) is influenced by season.
ABSTRACT. Chemical signals play an important role in social and sexual recognition in several lizard species. Here, we investigated whether the lizard Liolaemus pacha can recognize their own chemical scents (i.e., self-recognition) from a control. In addit...

... Reptiles and amphibians contribute 33 species. The BC Conservation Data Centre considers the pygmy short-horned lizard (Phrynosoma douglasii) extirpated, but there is recent evidence it may still be present (Ryder et al. 2006). We included it in our tallies. ...
The authors summarize the distribution of terrestrial vertebrates of British Columbia across major habitat
types and present empirical and projected effects of global weirding within two particularly vulnerable
habitats—alpine and wetland. Global weirding embraces all phenomena associated with climate change:
increases in average temperatures, heat waves, cold spells, floods, droughts, hurricanes, blizzards, plant and animal die-offs, population explosions, new animal migration patterns, plus dramatic regional differences. Current data suggest that many alpine species will be lost to changes in habitat wrought by climate, particularly increases in average temperatures. For many wetlands, particularly in the central and southern interior of the province, the basic issue is simple—the incoming water is decreasing and the outgoing water (evaporation) is increasing. The authors illustrate three approaches to projecting trends in wetland habitat, elaborating on the “drying index” approach, in which they have most confidence. For wetland species, they say management will struggle with the concept of a real-world triage—allocating conservation efforts where they are most likely to succeed and have the most benefit. They conclude that several conservation approaches for wetland species will face the difficulty of allocating water between needs of these species and of humans.
