El Yunque: In Search of Coqui

January 28th, 2017tinalc0 Comments

After several Google searches and a few beers we decided on a trip to Puerto Rico to see the iconic Coqui frog. Neither Andy nor I had ever visited the Caribbean before; therefore, we had no preconceived notions of what to expect. We knew there would be beautiful beaches surrounded by sky-blue water and a rainforest, and that was good enough for us. As the plane touched down in Old San Juan we collected our bags and headed to the rental car counter. We learned a lesson from our recent trip to the South Pacific; pack light and pack …

Dispelling Wildlife Myths- Halloween Edition

October 23rd, 2012tinalc0 Comments

With Halloween right around the corner, I thought it the perfect time to address some common misunderstandings about wildlife. We have all heard them. Whether they are called myths or Old Wives Tales most false accusations conjure up fear that sometimes result in the persecution and death of many innocent species. How many times have you heard someone say that toads give people warts? I myself have been told this on more occasions then I care to remember. The idea that touching or just looking at a toad can cause a skin malady is simply not true. Although some species, …

Animal Extinctions: What Can We Learn From Past Mistakes

April 30th, 2012tinalc0 Comments

Across the globe animal species are going extinct. From such contributing factors such as disease, persecution, poaching, displacement, and habitat destruction, we are losing some of our most amazing creatures at an alarming rate. Unfortunately, species extinctions are nothing new. But can we learn from past mistakes to ensure more magnificent animals do not do the way of the dodo? One of the most iconic species to have become extinct in the 20th Century was the thylacine or Tasmanian tiger. The last known thylacine was observed in captivity at the Hobart Zoo in 1936. Although the thylacine was a large …

The Importance of Citizen Scientists

April 14th, 2012tinalc0 Comments

As science itself evolves, a new way of conducting research is emerging. Although a newly coined phrase, Citizen Scientists have been around for a very long time, lending a helping hand to researchers around the globe. Although these individuals may lack a formal education, what they do not lack is passion and enthusiasm. Participation of Citizen Scientists essential allows scientists to be in millions of places at one time; observing wildlife, recording behaviors, and biological sample collection is but a few things they do. One of the original programs initiated by Citizen Scientists was bird watching. Although a hobby for …

Chrysosporium in the Massasauga Rattlesnake

March 26th, 2012tinalc0 Comments

A deadly threat has been identified in a Southern Illinois population of Massasauga rattlesnakes (Sistrurus catenatus). In 2008, biologists found 3 eastern massasaugas with disfiguring lesions on and around their head. In addition, the snakes had multiple growths and ulcers, and experienced swelling that extended throughout the skin and skeletal muscle. Another massasauga with a similar condition was documented in the same area in 2010. Unfortunately, all snakes died. Cultures taken from infected individuals identified the disease causing pathogen as Chrysosporium, a soil dwelling fungus commonly found in pet reptiles but rarely seen in the wild. To date, Chrysosporium has …

Invasion of the Habitat Snatchers

January 21st, 2012tinalc0 Comments

Non-native or invasive species are finding their way into ecosystems all around the world. Regardless if they are being purposefully introduced by biologists to predate on a more destructive non-native or to enhance a biological area, or if they are being released by irresponsible pet owners, non-natives threaten native species. More importantly, invasive species not only pose a risk to native plants and animals through displacement, competition, or predation, but also by the possible introduction of disease. One of the most well-known stories of a non-native invasion is the cane toad of Australia. Brought to Australia in 1935, the cane …

Habitat Preservation and the Discovery of New Species

November 29th, 2011tinalc0 Comments

It is hard to believe that in a world where the human population now exceeds 7 billion, that there are still unexplored wild areas, and new plant and animal species being discovered. I think it is easy to understand the importance of preserving oceans, jungles, rainforests, grasslands, and deserts (yes, even deserts) for the known species that inhabit them, but what about the places that are home to creatures yet to be discovered? What about the plants, bacteria, or fungi in those wild areas that could lead to new breakthroughs in medicine? And, although hard to imagine, should we not …

Snakes, Spiders, and Bats…Oh My!

October 23rd, 2011tinalc0 Comments

In preparation for my favorite holiday, I was recently perusing through the Halloween decorations at a local megastore. For me, Halloween standards are carved pumpkins, bed sheet ghosts, and candy; lots of candy. However, for others, the scariest of holidays is all about fear. Some of the most iconic Halloween characters that makes ones blood run cold and stand frozen in fear, i.e., bats, spiders, and snakes, are the same creatures I find most fascinating. Unfortunately, it is this very fear that has served as a death sentence for those same misunderstood species that actually do a great deal to …

Chytrid Fungus and the Global Decline of Amphibians

August 28th, 2011tinalc0 Comments

Recently, I had the privilege of spending time with a biologist studying the impact of the chytrid fungus on amphibian populations, as well as some of the beautiful Panamanian Golden Frogs (Atelopus zeteki) in her study. Chytrid is a type of fungus that is exclusively found in water or in moist environments. Although there are over 1,000 identified chytrid species it is the Batrachochytrium dendrobatidis that has been traversing the globe decimating amphibian populations. First identified in 1998, the B. dendrobatids species of chytrid has been found to infect the skin of amphibians; infection causes the skin to thicken. The …
