This month it was the turn of The Vivarium and Nature’s Library galleries to open up an hour early, during which time we ran a number of activities and handling tables to help make this event extra special.
I was able to introduce these lucky visitors to some animals from our collection, chiefly the royal python and some of our fire salamanders, who all proved to be big hits with everyone, even those who were a little scared at first were won over in the end.

As you can see from these pictures everyone, I myself included, had a great time and it was a real pleasure to take part.

Animals have a remarkable ability to connect and amaze all kinds of people and the joy they generate is something worth cherishing. A quick thank you is in order to all those who took part and who attended and helped make the morning such a success.

Visit to the Atlanta Botanical Gardens

Me outside frog podLast week I was spending time with Mark Mandica and his team at the Atlanta Botanical Gardens.  Mark leads the Gardens amphibian conservation programme, which houses many endangered species of Panamanian Amphibians within their Frog Pod, a bio secure unit used to house and breed amphibians.  They lead on conservation breeding of the Panamanian Lemur Leaf Frog, as apposed to our Costa Rican population here at the Museum.

I spent much of my time working alongside Mark’s extremely focused team, which includes Dr Brad Wilson, who as well as working with the amphibians at the gardens is also the veterinary consultant for the Amphibian Ark.  One of the main purposes of this visit was to exchange ideas and learn new skills that I can now bring back to our work at The Vivarium in Manchester.

Opportunities such as this are essential for developing successful and mutual collaboration between our institutions, which are ultimately working towards the same goal: Amphibian conservation.

I would like to thank Leslie Phillips and Brad Wilson for their time during the past week, and a special thanks to Mark Mandica for organising such a great and busy week for me; from helping out in the frog pod to searching underneath logs for native salamanders, it really was an amazing visit!

Surveying Amphibians in South West Georgia USA

For the past week I have been working alongside Mark Mandica and his team at the Atlanta Botanical Gardens, which boasts an impressive collection of neotropical frogs much like our own in Manchester.

You don’t have to be in the tropics to find areas with amazing reptile and amphibian diversity, as I have found this week whilst assisting with field surveys of native species in south Georgia, which the Atlanta Botanical Gardens is heavily involved in. We recently travelled to the far South West of Georgia to a protected area that is home to many reptiles and amphibians.

This is one of the sites where the Gopher frog (Rana capito), one of Georgia’s most endangered amphibians, has been introduced using frogs raised at the botanical gardens.

Gopher frogs get their name because they spend the day hiding within the sandy burrows of the gopher tortoise (Gopherus polyphemus). They emerge very early on in the year to breed in temporary breeding sites. This field study was aiming to record any early activity in the species.

The entire population of Gopher frogs at this site consists of introduced frogs which have only recently been recorded reproducing here.  Although we did not find any gopher frogs or their eggs on this trip, the technique used to search for them is incredibly fun!  We spent time during the day searching Gopher Tortoise burrows using a specialised camera that can reach deep into the burrows, which often resulted in confused tortoises looking back at us through the screen!

The temporary breeding sites used by the gopher frogs are also used by many other species which breed early on in the year. This is because by the time summer arrives, the temporary ponds here usually dry up.  Breeding early, even when its very cold means they all get a good head start, and in the water on the morning of the survey we found fresh spawn produced by leopard frogs (Lithobates sphenocephalus).

The edges of the pond that we surveyed teemed with tadpoles of at least three species of amphibian, and adult frogs could be heard calling throughout the entire day – and wheres there’s frogs, there’s frog eaters! We were also lucky to find a large banded water snake (Nerodia fasciata) curled up in a patch of sunlight on the forest floor.

This has definitely been one of the most amazing areas to search for amphibians, the diversity has been incredible and I haven’t even touched on the salamanders that we spent the rest of the day searching for!

Research being conducting with our collection is helping us understand such things as water loss and temperature regulation in amphibians, and in the case of leaf frogs, heat load transfer due to their ability to reflect infra-red light. Leaf-sitting, sun-loving frogs are highly adapted, reflecting light at a wavelength not so far seen in any other type of creature, or amphibian for that matter. It’s seen only in the very leaves they sit on.

Some species have even evolved incredibly extensive flanges and unusual flaps of skin to extend their surface areas, which, when the frogs are sleeping, acts as a dermal covering to support an increase in body temperature control and also enhance their highly cryptic camouflage when sleeping. These leaf frogs belong to the genus Cruziohyla, which consists of 2 species, The Fringed Leaf Frog, Cruziohyla craspedopus, and the Splendid Leaf Frog, Cruziohyla calcarifer.

Collaborative research with our Photon Science Institute has allowed us to investigate many aspects of the frog’s biology, and that we maintain these rare frogs in the collection provides some wonderful opportunities for non-invasive studies.

DSC_0710_1At the moment I am co-supervising an excellent student, Francisco, from Mexico, who is making great headway investigating aspects associated with the dorsal surface area of the frogs. He is accurately mapping the area concerned through the development of a revolutionary 3D modelling technique, using a completely new way of evaluating their morphology and physiological parameters.

This week or so has been particularly interesting, as while filming the frogs in question from all angles on a turntable, to facilitate the 3D modelling, we were surprised how the animals maintained focus on one object in their view…

so much so that even when they’re body was turned they just couldn’t help but keep staring in that same direction – it made for some quite difficult but very amusing filming!
