Male Green Frogs in Suburban Habitats Sometimes Develop Eggs

Interesting video of the now:


I hope you enjoyed that. I post it not only because of the interesting topic, but the simple manner by which a complex process is described. As I look into graduate school more and more, I'll probably be posting videos similar in feel to this one. This is simply because visiting research lab websites exposes me to, well, lab research.

Museum of Living Art (MOLA) - Now Open

Posted by Alex H. |1 comments

As summer approaches, I am getting mixed news about what I'll be doing for the next few months. I had applied to several internships, but none of them had positions open :/

One place that I am interested in is the Forth Worth Zoo. I had a post at the beginning of the year which described the zoo and a new exhibit - the Museum of Living Art (MOLA). This exhibit replaces their Herpetarium built in 1960.

Upon visiting the FW Zoo's website, I see that MOLA opened in March of this year!

Check out their over-the-top promotional videos here or here.

The size and scope of the exhibit are phenomenal. The 30,000 sq. ft. facility houses (at current) around 1,000 individuals representing a hundred different species of reptiles and amphibians.

I'm super-pumped! I'll report in when I have the chance to visit them next.

Update: When searching for images for this article, I spotted one of my pictures in the top results of a Google Search. Moving up the food chain. We also recently hit 1,000 pageviews. Hooray!:

Museum of Living Art

2009 was a rough year for everyone. Possibly the least popular year of the decade. One of the biggest let-downs I experienced in 2009 was the delayed opening for the Fort Worth Zoo's Museum of Living Art. Before I explain, allow me to remind you that my family visited the Ft. Worth Zoo last year with intentions of seeing some progress on this world-class project. Unfortunately, it appeared that delays had pushed its opening to sometime this spring.

What the heck am I talking about, pray tell? Only the construction of the world's most awesome herpetarium (like an aquarium, but for reptiles and amphibians)! This thing's going to be huge - probably the largest in the world (both in square footage, number of species, and possibly number of individuals).

When the zoo's current herpetarium opened in 1960, it held more species of reptiles and amphibians than any other facility. Throughout it's history, the staff have been responsible for the breeding of several individuals, included many rare and endangered species. This new facility will continue their previous vision, but with the world-class resources deserving of their world class efforts. In addition to housing more species than any other facility, the MOLA will continue and expand upon their significant conservation efforts for amphibians (If you would like to know more about their conservation efforts, read this article here).

The MOLA will have several different "habitat" areas for viewing by patrons, including a deserts, swamplands, and rain forests. Just check out this huge list of species the MOLA will be keeping, or should I say curating? If that doesn't get you salivating, you can view the online floor-plan for the new facility which indicates generally what will be exhibited. For zoo activity in the new decade, keep an eye out for the MOLA.

Here are two shinglebacks in the Fort Worth Zoo's current herpetarium. Shinglebacks are highly monogamous (single pair breeders). There are cases of them breeding with their mate (to the exclusion of other individuals) for up to twenty years:

Reptile Communal Nesting

Check out this cool article about normally-solitary reptiles laying eggs in communal nests.

Communal nesting!? What's that, Alex? For one, it has traditionally been thought of as a non-reptilian behavior. Communal nesting is simply the laying of eggs by a female animal into the nest of a conspecific (same species) animal. This behavior is different than cooperative breeding, which could be thought of as a "daycare system" - individuals care for the young of other individuals, even at the expense of their own breeding abilities.

A quote that summarizes the opinions of the authors on why communal nesting occurs in some reptiles:

Building a nest can be hard work for reptiles. Some female lizards, for example, may spend days digging a hole deep enough to deposit eggs. During those days, she is not doing other important things such as finding food. She is also more vulnerable to predators. Females can avoid these costs by simply laying eggs in a nest that someone else has gone to the trouble to build.

The model, the authors argue, could be advantageous in an evolutionary sense. It is common sense to note that anything that reduce an animal's required level of energy expenditure to successfully pass on genetic material is good for the species in the long-run. This argument does NOT always hold true; however, that's the common sense approach. It is still true that parental care is not the norm in most described species behaviors THUS FAR, but read on...

While searching around for the topic, I found another well-cited article summarizing review articles (articles that synthesize scientific literature) which argues that communal nesting is probably much more common in reptilian species than first thought. If you read through the article, you note how little is known about nests in most species of reptiles. In fact, for most named species, nests have never even been reported in the scientific literature! Just another opportunity to grab your hiking boots and go outside!
