Question

Question 1: research students have been setting up pitfall trap arrays in sandy habitats throughout the Mojave Desert. The traps were set over night and are much like the caterpillar arrays described in Cushing et al. (2018). Should they be worried about accidentally catching any amphibians or reptiles in our traps? Which ones?

Question 2: The furthest east we went this trip was near Las Vegas, Nevada. Another site was near Newberry Springs, California. Identify two reptiles or amphibians genus & species! that could be found at one site but not the other. Explain why you think they should or should not occur at each site.

Explanation / Answer

1. Pitfall trap array is a mechanism of trapping small vertebrates. Since Mojave desert has a high diversity of amphibians and reptiles therefore some of them can be accidentally trapped. Fringe toad frog, Red spotted toad, desert Iguana, ,Horned toad, are some e example of amphibians. Mojave Green Rattlesnake, Rosy - boa snake and female long nosed leopard are some of the common reptiles to get trapped in the pitfall trap

2. Bearded Dragons and common Leopard gecko are common reptiles in Las Vegas Nevada and are absent in Newberry Springs, California. Mainly venomous Rattlesnake and Local Rosys are common in Newberry Springs, California. This is due to the variation in environment in the two place which supports the survival of these species properly
