Re: non-fiction pleasure reading?

As far as books on natural history go, I prefer the oldies, and would recommend any of William Beebe's books, particularly those which deal with this travels and studies in forests of Guyana and Venezuela (Jungle Days, Jungle Peace, Edge of the Jungle, and High Jungle). His books Galapagos: World's ...

Re: Bornean Earless Lizard (Lanthanotus borneensis)

Lanthanotus are strange animals indeed... I was hoping to miraculously encounter one during my brief time in Sarawak this past July, but no such luck. I guess for now I'll have to make do with pickled stuff.

Re: Costa Rica inquiry-mid Pacific coast cruising/lodging/hi

About 45 km south of Quepos/M.A. is Dominical, a quiet surfer town. Just a few km up the road from Dominical is Parque Reptilandia, a must see reptile zoo owned and operated by an American expat. Just a few km past the zoo are hiking trails to Nuayaca Falls- a nice, healthy hike up to some spectacul...

Very cool stuff, Bob. Do you know which issue of Herp Review it'll be in? I look forward to reading the report. Have you tried similar experiments with any other members of the prasinus complex, or other species of varanids? It appears in Vol. 42 No. 3 which should be arriving in people's mailboxes...

Re: A clever foraging tactic in arboreal monitor lizards

Great observations and video. Are the 3rd and 4th fingers on that monitor longer than normal? Perhaps if they are longer it is specifically for this purpose! While I am not sure if the long and slender limbs and digits evolved in response to this type of foraging (i.e., a potentially unused/open ni...

Re: A clever foraging tactic in arboreal monitor lizards

Does the lizard scrape the food item out or grasp it and pull it out. I know that lizard has the capability to grasp. It does look like a unique instinctive behavior... ...I'd still like to know if the lizard grabbed the prey or if it dragged it out? I'd say it's a combination of the two. From what...

Given the apparent ease at which chytrid fungus is spread, and the incredible durability of its spores, it's reasonable to assume that amateur field herpers and researchers are (unknowingly) doing their part to spread this pathogen from one body of water to another, whether it's through contaminated...
