Population Ecology Studies of Eastern Fence Lizards, Sceloporus undulatus, in the New Jersey Pine Barrens

In Summer 2007, my students and I restarted field studies in the heart of the NJ Pine Barrens on a 4.5 hectare site near Tabernacle, NJ. This is the same site that Widener students and I worked from 1994 to 1998 during which we captured or recaptured 553 lizards (211 unique), and recorded 1272 observations of lizard home ranges and social interactions. NJ Fence Lizards exhibit unique life histories compared to populations studied elsewhere (slow individual growth rates, delayed sexual maturity, females larger than males). Data also show the huge effects of El Niño years on these lizards that reveal the complex challenge of biodiversity conservation amidst climate change. This is a very exciting project, and things now are very different -- the population has crashed, possibly due to the recent spate of severe El Niños in the last few winters?!?

Sceloporus undulatus

Population Ecology Studies of Fowler's Toads, Bufo fowleri, in the New Jersey Pine Barrens

In Summer 2007, as my students and I restarted field studies on Eastern Fence Lizards (Sceloporus undulatus) in the heart of the NJ Pine Barrens in Tabernacle, NJ (see above), we noticed that the site was quite literally hopping with toads. I have never seen numbers as large as these, but that isn't the only surprising thing. Remember, toads lay eggs in water, and all of the standing water in the Pine Barrens is highly acidic (pH's around 4.5), which causes acid death for amphibians in our area of PA. So, let's find out "why" there are so many Fowler's Toads in the Pine Barrens -- where do they live and breed, what life histories have evolved in these populations as potential adaptations to environment, and how might these populations respond in evolutionary time to presently occurring landscape and climate change? This is a brand new and very exciting project for us to begin.

Bufo fowleri

Population Ecology Studies of Red-Backed Salamanders, Plethodon cinereus, in Delaware County, PA

Red-Backed Salamanders, Plethodon cinereus, are among the most common vertebrates in urban forests in eastern North America. In all but the most heavily impacted forest or woodlot, P. cinereus numbers can reach hundreds per hectare, and they are often the dominant invertebrate-eating animal in ecological food chains. Despite extensive population studies of P. cinereus in rural or wilderness areas, almost nothing is known about their life history and population ecology in urban areas. In fall 2006, my students and I began studies of a population in Houston Park, only one mile from Widener. The goals of this project are -- what are salamander population sizes, where do they live and breed, what life histories have evolved in these populations as potential adaptations to environment, and how might these populations respond in evolutionary time to presently occurring landscape and climate change?

Plethodon cinereus

Behavioral Ecology Studies of Soil Acidity Preferences by Fowler's Toads, Bufo fowleri, in a Lab pH Gradient

Fowler's Toads, Bufo fowleri, are the common toad in the New Jersey Pine Barrens on my research site for Eastern Fence Lizards. The Pine Barrens exhibit highly acidic sandy soils and surrounding bogs (pH = 4 to 5) where toads live and breed. Yet, it is widely known that environmental acidification causes amphibian decline elsewhere, and published research by Widener Faculty and Students has shown that compromised immune systems due to acidity can be an important cause of death. I ask -- how are these toads able to survive and breed in the high acidity in the heart of the Pine Barrens? Do the toads distinguish between and orient either towards or away from acidic soil conditions? To address these questions, I use a simple soil pH choice apparatus in lab. By recording toad movements, one can test hypotheses about orientation behavior and pH preferences.

Amphibian Behavior

Bioenergetics Research on Energy Budgets and Life Histories of Reptiles and Amphibians

These studies are in collaboration with Dr. Itzick Vatnick (at right), with whom I have co-taught courses and collaborated on bioenergetics research projects since 1993 when we both arrived at Widener. We have a Sable Systems oxygen and carbon dioxide analysis system capable of whole-organism metabolism under controlled temperature conditions, and data from this apparatus has led to dozens of faculty*student collaborative projects, off campus presentations, and publications over the past decade. My interests are in understanding metabolism, food processing, and life history energy allocation in three separate study systems for each of which I have field projects previously described: Eastern Fence Lizards (Sceloporus undulatus), Fowler's Toads (Bufo fowleri), and Red-Backed Salamanders (Plethodon cinereus).

Urban Ecosystems: The New Frontier in Ecological Research

We all live in the dominant ecosystem type on the Earth today -- urban ecosystems. Currently, more than half of humanity lives in urban ecosystems, and the ecological effects of urban ecosystem resource demands (energy, water, and materials) extend widely to all other ecosystem types. Urban ecosystem ecology has been the principal research focus of a wide range of the courses I teach -- from Freshman Introductory Biology (Bio161) to my upper level Ecology and Conservation Biology courses. Projects have examined urban effects on terrestrial and aquatic plant and animal biodiversity, and may of these course-based projects have led to follow-up research independent projects and student presentations on and off campus.

Practitioner Research in Ecological & Science Education

Practitioner research is a teacher*researcher paradigm that uses scientific evidence to measure the effects of curriculum and instruction on student learning. In other words -- what is the evidence that students are learning as a result of teaching? Since coming to Widener in 1993, I have used and developed new methods in inquiry-based instruction through practitioner research to improve my teaching and my students' learning in all of my courses: freshman to senior. In addition, I have been active with folks in the Ecological Society of America to create a peer reviewed journal of ecological educational materials and research scholarship now in its 6th volume (Teaching Issues and Experiments in Ecology, TIEE, http://tiee.ecoed.net). This journal was funded by the National Science Foundation (>$600,000) since 2000. I am currently pursuing parallel projects with the British Ecological Society. Locally, I am active with Widener's Science Teaching Center and its program Ecology Education to Teach Math, Engineering, Technology, & Science (EcoMETS). Lastly, we just received $300,000 from NSF to create a multi-university Masters degree program in education for teachers in the new and emerging field of "Sustainability Science" !!!

Academic Service Learning: Researching a New Pedagogy to Teach Science and Civic Engagement

Research has shown that courses that engage students in academic service learning (ASL) improve students' multicultural awareness, social responsibility and agency, and citizenship. However, for academic subdisciplines such as the sciences, less is known about how ASL can affect student learning and improve students’ performance in their majors. What is needed is scientific evidence to test if the pedagogy of academic service learning can enhance academic learning, too. To pursue this research question, I designed a new course (Service Learning in Biology – Teaching Concepts of Freshman Biology to Middle School Students, Bio172), in which I take freshmen science majors to the Smedley Middle School (one block off-campus) and we offer life science education sessions for 6th-8th graders.
