Undergraduates:

Natural History of a West Indian Herpetofauna

Critically endangered Cyclura ricordii from Parque Nacional Isla Cabritos, República Dominicana

 

REU PHILOSOPHY

Our REU philosophy is best summarized as a composite of four basic statements: (1) participating students are to be afforded the opportunity to engage fully in the complete scientific process, from conceiving an idea, implementing an investigation, to analyzing and presenting cogently their results; (2) students will think, not accept information passively, but question, analyze, and test via applications of their newly acquired knowledge and skills; (3) they shall enjoy the experience; and (4) they will presented with information and guidance to facilitate their exploration of career options. If, in the process, the participating faculty receive support for their own research interests, so much the better.

In practice, students must acquire a working knowledge of the fundamental principles and associated terminology of a given research area. Much of this material is best gleaned from the primary literature, which students must learn to use effectively. Higher-level thinking skills (e.g., integration, analysis, and decision-making) must be explained, modeled, and practiced. These activities (and these are active processes) are almost always best accomplished in the biological sciences by letting and encouraging (and occasionally forcing) the students to get their hands dirty.

As learning is an incremental process during which the student builds on a known foundation by making connections with new, previously unknown, but related information and skills, frequent feedback is essential, initially under circumstances entailing limited risk. Minimizing risk and providing frequent feedback enhances the student's opportunity for success. A challenge is provided by the very nature of the scientific endeavor—and research is, of course, at the very heart of science. The role of the faculty in this learning progression is to encourage an ever-increasing independence by shifting their own roles from initial guidance through facilitation and, finally, to mere assistance.

In summary, students will be challenged to succeed in the program and in pursuit of career goals as they learn to “do science” by establishing a knowledge base and then applying that knowledge and related skills to very real and stimulating research projects.

 

PREVIOUS REU PROGRAMS AT AVILA UNIVERSITY

 

     

 

  

Avila University has sponsored ten previous REU Programs in 1991, 1993, 1995, and 1999 to the Dominican Republic, 2000 to Anguilla, 2002 to Grenada, 2004 to St. Eustatius, 2006 to St. Vincent, 2008 to Dominica, 2010 to Union Island in the Grenadines, and 2012 to Eleuthera Island in the Bahamas. A total of 101 students from 68 different colleges and universities have participated.

.

All participants in Avila REU Programs have published the results of their research in scientific journals (or will, in the case of the 2010 participants). See the list of student-authored publications listed below.

Scott Sowell (University of North Florida) and Bob Powell look for hybrid anoles in a palm in Barahona, Dominican Republic

  

 

  

 

The Avila University REU Programs include 1–2 weeks of training and preparation, 3 weeks in the tropics, and 5 weeks devoted to data analysis and the preparation of presentations and manuscripts.

Tim Fobes (left, Northwest Missouri StateUniversity), Mike Schreiber (with camera, Rockhurst University), Hua Bui (blue shirt, University of Missouri-Kansas City), and Pete Zani (kneeling, Miami University) look on as Lisa White (Miami-Dade Community College) and Bob Powell discuss a recently captured specimen.

 

Research projects are chosen, designed, and implemented by students under the guidance of faculty with experience in herpetological research.

Kim Schneider (University of Florida) and Andrew Hardwick (Fontbonne College) use a "paint-gun" to spray lizards in order to estimate population sizes.

  

  Most projects have addressed aspects of natural history of frogs and squamate reptiles but, triggered by the diverse interests of participants, topics have ranged far afield — descriptions of new parasites and studies of the phylogeny of an introduced species, hybridization, and behavior.

Matt Gifford (Avila University) searches for sleeping lizards at night.

Study sites in the Dominican Republic have ranged from high-elevation pine- and cloudforests, mid-elevation rainforests, to low-elevation deserts.

Roland Sosa (San Diego State University and Loma Linda University) removes an interloper from a "sticky trap" placed to catch secretive, nocturnal lizards. Roland participated in the '95 program and joined the '99 program as a member of the faculty.

 

  

 

In 2000, we conducted research on Anguilla, where the herpetofauna is considerably less diverse than on Hispaniola. In addition to work on native species, we also documented the colonization of two exotic forms introduced by humans.

Stesha Pasachnik (Earlham College) uses a cliffside vantage point to observe activity of critically endangered Anguillian iguanas (Iguana delicatissima).

Even on a small island like Anguilla, environmental conditions vary from site to site, affecting the relationships between animals and the local climate.

April White (Southwest Missouri State University) seeks to capture an Anguillian Ground Lizard (Ameiva plei) using a noose fashioned from a fishing pole (upper left). The noosed lizards (upper right) were unceremoniously subjected to having their temperatures taken (lower) for a study of thermal biology.

 

  

.

  

The fieldwork is intense, although students have been known to take a break by visiting the beach or playing tourist.

Saul Nava (University of Texas at El Paso) collects data on the microhabitat of a Dwarf Gecko (Sphaerodactylus parvus)

.

Although this hillside on Grenada looks like pristine forest, all except the steepest slopes have been converted to agriculture — in this case, banana and nutmeg (the latter contributing to Grenada becoming known as the "spice island").

Jenny Germano (Miami University) and Jenn Sander (Lee University) collect data on the composition of herpetofaunal communities in variously altered habitats

  

 

Although the tropical sun is intense, students soon become acclimated to the climate.

Brian Greene (Wofford College) works to noose a Grenadian Ground Lizard (Ameiva ameiva).

.

Sometimes field studies require getting to know your subjects.

Kate Williamson (Ohio Wesleyan University) holds an anole (Anolis aeneus)

  

 

 

  
Higher elevations on The Quill, a 600-m high volcanic peak on St. Eustatius, support diverse biotic communities.

 

Aaron Savit ( St. John's College, now at Earlham College) watches a Red-bellied Racer (Alsophis rufiventris) forage through the litter on the slopes of The Quill.

 

 

Projects often include methods used to estimate population sizes.

Sarah Wissman ( University of New England, left) and Randa Hensley ( Haskell Indian Nations University) laying out a transect on the slopes of The Quill.

 

  

 

  

 

Low areas on tropical islands are often very dry.

Trevor Joyce ( University of Alaska) conducted a study in the dry, rugged hills of the Boven sector on St. Eustatius.

 

.

"Doing" biology means getting to know your subjects.

Pamela Medina Díaz ( University of Puerto Rico) and a Red-bellied Racer (Alsophis rufiventris).

  

 

  

Mark-recapture projects involve catching animals that often don't cooperate.

Angela Kerr ( Western Illinois University) attempting to noose a Ground Lizard (Ameiva erythrocephala).

 

.

Technology is helpful when videotaping the foraging behavior of treeboas at night.

Alex Muensch (Avila University) and Helen Arnold (Arkansas State University-Beebe) try to follow a Cook's Treeboa (Corallus cookii) as it forages for sleeping lizards on St. Vincent.

  

 

  

Some subjects of research projects are not shy.

Alex Muensch ( Avila University) and a Cook's Treeboa (Corallus cookii).

 

.

Assessing population densities and microhabitat associations involves marking animals (in this case, with a "paintgun").

Carlos Rodríguez (University of Puerto Rico-Río Piedras) "shoots" an anole high overhead on a palm tree.

  

 

 

Close personal contact with the research subject isn't usually recommended.

Chris Mallery ( Willam Patterson University) and a Green Iguana (Iguana iguana).

 

.

Sometimes you have to hike to a study site.

David Steinberg (Vanderbilt University) and Jessica Hite (University of Tennessee) return from sampling plots for Dwarf Geckos (Sphaerodactylus vincenti).

  

 

 

Getting to know your research subjects is important.

Sylvia Powell (Earlham College) and Mike Treglia (Cornell University) examined habitat associations of Cook's Treeboas (Corallus cookii).

 

.

For some types of studies you have to get your hands on your subjects.

Esther Daniells (Colorado State University) draws blood for DNA analysis from a Lesser Antillean Iguana (Iguana delicatissima) on Dominica. Lyndon Prince, who is working on a long-term study of iguanas on Dominica, is holding the iguana.

  

 

 

Recognizing individuals can be critically important.

Patrick Turk (Avila University) and Natalie Wyszinski (University of Tennessee) are painting a number on a Lesser Antillean Iguana (Iguana delicatissima) to facilitate individual recognition.

 

.

Fieldwork in the tropics can be hot and sweaty.

Nelson Vélez (University of Puerto Rico) marks a Dominican Anole (Anolis oculatus) with a unique paint pattern in order to trace individual movements and behavior.

  

 

 

Although often not the focus of any project, encounters with rarely seen species can add some spice to the tropical experience.

Seth Rudman (University of Rochester) examining a Dominican Clouded Boa (Boa nebulosa) up close.

 

.

Getting to some animals requires a willingness to crawl into tight spots.

Ehren Bentz (Feather River College, now at Oregon State University) trying to catch a crevice-dwelling Union Island Gecko (Gonatodes daudini).

  

 

 

Accurate data are critically important.

Audrey McTaggart (McPherson College) records the number of litter-dwelling lizards encountered in a plot sample.

 

.

A photographic record of encounters is important in documenting new findings.

Mel Rivera (University of Puerto Rico at Mayagüez) photographs a White Snake (Mastigodryas bruesi) encountered during a survey of a critical habitat in the area above Chatham Bay on Union Island.

  

 

 

Unexpected encounters can provide valuable data.

Tess Bellah (Avila University) holds a Grenada Bank Treeboa (Corallus grenadensis) found along the trail to Bloody Bay, where students were hoping to see nesting Leatherback Sea Turtles (Dermochelys coriacea).

 

.

Sometimes you have to make sacrifices to catch animals.

Ehren Bentz (Feather River College, now at Oregon State University) with a Green Iguana (Iguana iguana) found on the Tobago Cays during a snorkeling trip.

NO REU PROGRAM WILL BE OFFERED IN 2013.

The information below applies to the program held in 2012 only.

 

2012 REU Program

 

Natural History of a West Indian Herpetofauna: Eleuthera (Bahamas)

 

Location of the Cape Eleuthera Institute on Eleuthera in the Bahamas

The Cape Eleuthera Institute, where we will be staying, is adjacent to the Island School, where we will be dining and whose facilities will be available for our use.

A peninsula adjacent to the Cape Eleuthera Institute might serve as a field site for some studies.

Tarpum Bay is another possible field study site..

The southernmost tip of Eleuthera is a windswept complex of habitats (beaches, cliffs, scrub vegetation) supporting populations of Leiocephalus, Ameiva, and Anolis.

Rocky outcrops along the western beaches of Cape Eleuthera will serve as the primary field site for studies of Leiocephalus carinatus.

WHEN AND WHERE?

The program begins at Avila University in Kansas City, Missouri on Monday, 21 May 2012 and ends on Friday, 27 July 2012.

The three-week field trip to Eleuthera will be in June 2012.

 

ELIGIBILITY

The program is open to undergraduates currently enrolled in an accredited two- or four-year college or university who will not graduate before December 2012.

Applicants must be U.S. citizens or permanent residents.

Applicants should have taken at least one science course and have an interest in pursuing a career in the natural sciences.

 

BENEFITS

The program will provide a $4500 stipend, all expenses associated with the field trip, and on-campus lodging for non-resident students.

An additional $800 is available for an accepted student residing outside the continental United States.

 

COSTS

Participants are financially responsible for travel to and from Kansas City, food while at Avila University, and tuition (at a reduced rate).

 

CREDIT

Students may earn up to 6 hrs of credit in biology research.

PROGRAM

Learn: (1) how to use the primary literature, (2) methods of field research, (3) computer applications (word processing, data analysis, graphics, presentations), (4) statistical data analysis, (5) writing for professional journals, (6) how to choose a graduate program, and (7) how to apply successfully to the graduate program of your choice.

Seminars: (1) natural and political history of the Bahamas, (2) political and economic realities in a developing nation, (3) tropical biology and conservation efforts in Caribbean nations, (4) how to write for science, (5) using a research library, (6) the role of natural history museums in biological research, (7) selection and application to graduate programs, and (8) ethics in biology and conservation.

 

POSSIBLE RESEARCH PROJECTS

Habitat Use, Performance, and Time Budgets of Curlytail Lizards (Leiocephalus carinatus)

 

 

 

 

Much of our research on this trip will address the relationships between natural history traits and measures of performance in Curlytail Lizards.

 

Natural History, Habitat Use, and Population Densities of Ground Lizards (Ameiva auberi)

 

These active foragers are locally abundant on Eleuthera.

 

Habitat Use and Foraging Behavior of Tree Lizards (Anolis sp.)

Three species of anoles are recorded from Eleuthera (the subadult in the photo is Anolis smaragdinus). The Brown Anole (A. sagrei) has been studied extensively, but projects relating to habitat partitioning among the three species or population densities in different habitats are available.

 

Other projects might address the abundance, habitat associations, behaviors, and performance of boas (Epicrates striatus), racers (Cubophis vudii), dwarf geckos (Sphaerodactylus ), or introduced House Geckos (Hemidactylus mabouia).

House Geckos (Hemidactylus mabouia) are abundant on most West Indian islands, but few island populations have been studied.

 

HOW TO APPLY

Download the application form, carefully read the instructions, and submit it with an essay stating your career goals and any particular interests and skills you might bring to the program, a transcript, and two letters of recommendation from faculty members who know you and can accurately assess your abilities.

Deadlines are critical. We must make reservations for the trip as early as possible.

We will begin accepting applications in January 2012.
