Evolution of a Lizard Room, Part X: Custom Cages for Breeding Experiments

The past six months have seen some radical changes to the lizard breeding cages used in the Glor Lab’s lizard room.  Because our space is very limited we needed new space-saving cages to accommodate a growing lizard population and to conduct additional breeding experiments.  Construction of new cages also afforded an opportunity to improve upon some of the problems with our old breeding cages, which were just the typical Kritter Keeper cages available at your local pet store.  Dan Scantlebury led our efforts to design new cages that improved security, eased access for feeding and other tasks, and minimized the space each cage takes up.

The new cages are composed of custom cut plexiglass and feature a front opening door secured with a magnetic latch.  Front opening doors are helpful because most anoles tend to shoot up and out of Kritter Keepers when you pull the lid off; in the new cages they tend to run to the back of the cage and escape less frequently.  On top, the new cages have a screen lid as well as a mini-hatch that can be opened at feeding time to supply crickets or other food items.  Where we once had five Kritter Keepers we can now have eight custom cages with similar internal volumes (due to the fact that new cages are taller and deeper than the Kritter Keepers).  Complete details on how to make these cages will be included in a post by Dan sometime after he gets back from his current field trip.

Panama Anole ID

A holiday quiz- can anyone ID this species? Found in the twilight zone of a cave in a small stream (hint) entering the main cave stream. Isla Bastimentos, Bocas del Toro Province, Panama. Apologies for the picture, one needs a good reason before hand to bring a nice camera into wet and muddy caves.

Has this species been reported from the BDT Archipelago?

Hungry Hungry Anole

Here’s another highlight from the collection of videos that the Glor Lab recorded during an expedition in the summer of 2010 (see our previously posted videos of a fight, color change, and mating).  This video is an interaction between a male Anolis distichus and a caterpillar.  This interaction left one of the participants with a good meal and the other, well, let’s just say he’s a part of the circle of life.

Gates Foundation Announces New Initiative to Eradicate Lizard Malaria

From Falk et al., 2011.

The Gates Foundation today announced a multi-billion dollar initiative to eradicate malaria from all lizardkind. Through a combination of heightened prophylactic use, development of genetically modified lacertilians, and enhanced mosquitivory, the Foundation hopes to eliminate this scourge, which afflicts millions of saurians throughout the world.

Well, maybe some day. But a recent paper on Anolis malaria set my mind a-wandering. Most people, likely the Gates Foundation included, are unaware that malaria is a disease not just of humans, but of many other species as well, including lizards. When I first learned that lizards got malaria, I thought it was just a curiosity, not of particular importance. However, I’ve come to realize that I was very wrong in a number of respects.

First, malaria in some cases can have substantial physiological effects on lizards (though this has yet to be demonstrated in anoles).

Happy Kwanzaa!

Anole Classics: Albert Schwartz (1968) on Geographic Variation in Anolis distichus

I previously characterized Albert Schwartz as one of the five kings of Greater Antillean anole taxonomy for having described eight new species from the region.  Although Schwartz described the fewest species among the five kings, focusing on new species masks Schwartz’s even more important contributions to cataloguing geographic variation within species.  Schwartz’s career-spanning interest in biogeography and geographic variation resulted in a prolific history of describing subspecies in anoles and other taxa.  Anyone who’s looked at Schwartz and Henderson’s classic book on West Indian reptiles and amphibians is familiar with the irregular blobs that designate subspecies boundaries on the range maps for many of the region’s most geographically widespread species.  Many of these blobs were the result of Schwartz’s own efforts.  The pinnacle of Schwartz’s work on geographic variation may be his 1968 monograph on geographic variation in Anolis distichus.

Merry Christmas!

Does Anolis Have a Google Problem?

Pop quiz: What do Anolis and Republican presidential candidate Rick Santorum have in common?  Answer: A Google problem.

Rick Santorum’s google problem is that the first hits you obtain when you google “Santorum” are related to the author Dan Savage’s efforts to criticize Santorum’s campaign against homosexuality.

What’s Anolis‘s google problem?  

Anoles as possible reservoirs for the chytrid fungus

Everyone knows the devastating effect that the chytrid fungus (Batrachochytrium dendrobatidis) has had on amphibian populations almost everywhere in the world–in 2009, it was estimated to infect at least 350 amphibian species on 6 continents.
