Center for Biodiversity and Ecosystem Stewardship (CBEST)

Global temperatures are rising, storms intensifying, rainfall patterns changing, seas swelling and nutrient pollution increasing—and the planet is losing animal and plant species before they are even named. Now, research in the natural sciences has never been more important and impactful.

Mission

The Center for Biodiversity and Ecosystem Stewardship (CBEST) seeks to promote research in biodiversity and ecosystem science with a focus on understanding ongoing changes in ecosystems, their component organisms, and the benefits they provide to society.

Upcoming Events

Julie Allen, Department of Biology, University of Nevada Reno will give a departmental seminar March 12 (Co-sponsored CBEST/Biology Department) and a Bioinformatics workshop the following Saturday, March 14, 2020.  More info to follow, including for signups for workshop.

CBEST and Engineering are teaming up for a Graduate Student Lightning Talk Symposium.  March 18, 2020.  Place/Time TBD.

CBEST cosponsors Earth Day keynote lecture featuring Katherine Hayhoe, Texas Tech University
April, 22, 2020.

Stay tuned for more info about our spring schedule, sign ups for workshop, and a yet to be determined time/place Future Career Discussion for interested students. 

Research

Sam Chapman and students conduct fieldwork.

Ecosystem Science

Ecosystem science examines the flow of energy and matter on Earth, or how ecosystems function. At sites that range from Canadian peatlands to tropical mangroves, CBEST faculty study how wetland ecosystems scrub carbon from our atmosphere and protect our shores from big storms. They deploy unique field-based experiments to simulate human-induced changes in temperatures, sea levels, and pollutants. These innovative and unique arrays allow them to predict how the earth’s wetlands can respond to an otherwise uncertain future.

Todd Jackman, PhD, and one of his student evaluate samples in the lab.

Biodiversity Science

Biodiversity science examines the evolutionary patterns of organisms that inhabit the earth. CBEST Faculty are discovering new species across the globe with a special focus on reptiles and their unique adaptations to life in diverse environments. They use innovative genetic and imaging techniques to explore how species have evolved in response to past climatic changes and how they might continue to do so on a changing planet. Their discoveries provide novel information on the distribution of animals in the evolutionary tree and throughout Earth’s history.

Education and Outreach

The Center fosters the education and development of undergraduate and graduate students as scientists, training them to effectively disseminate their findings. CBEST provides a public platform for the local Villanova community and beyondto engage in educational opportunities and understand the influence of human activities on the Earth’s biodiversity and ecosystems locally, regionally and globally. Through research and community interactions, CBEST explores solutions that can enhance human stewardship of the richness of life on Earth.

Dr. Daniel Pincheira-Donoso

Most recently, we wish to thank Dr. Daniel Pincheira-Donoso who hails from Queen's University Belfast for an illuminating and eloquent public lecture given here on campus.  Dr. Pincheira-Donoso highlighted species declines globally with an emphasis on amphibians.  Something to think about is that data suggests "biodiversity hotspots" rarely equate to "extinction hotspots".

Center Launch, featuring Jonathan Losos, PhD, is a success

The Center's launch event, featuring keynote speaker Jonathan Losos, PhD, was well attended and a great success. Dr. Losos, a renowned evolutionary biologist, professor of Biology and the William H. Danforth Distinguished University Professor at Washington University in St. Louis, gave an insightful talk about his research on lizard adaptation in the Bahamas. View the lecture

Faculty Mentors Key to Biology Student’s Graduate Experience

Emily Geoghegan ’19 MS has been interested in nature and the environment since elementary school, but it wasn’t until after taking some influential courses in college that she decided she wanted to pursue a career in ecosystems science. As a master's student Geoghegan worked with CBEST faculty member Samatha Chapman, PhD, on her NSF-funded wetland protection study. Read more

A menagerie of 20 microendemic and critically endangered reptiles newly described

CBEST’s Aaron Bauer has described more than 205 reptiles (Read more) -more than any other living scientist. This year, he adds another 20 to the tree of life. Bauer recommends that many of these reptiles be listed as critically endangered due to their microendemism—a term used to describe species only found in an extremely small geographic range. These animals are particularly susceptible to disturbance and we are reminded that the interconnection and rich diversity of plants and animals is what allows life on Earth to thrive. Finding these microendemic species is crucial for conservation. Read more

CBEST featured in KYW Newsradio, "Villanova's new biodiversity research center wants to make findings more understandable to public"

Kel Wieder, PhD, talks to KYW Newsradio about CBEST, the Center's mission and the obligation scientists have to communicate their research. "Nowadays, scientists and academic institutions have an obligation to make their work understandable to the general public and to explain how it's relevant and important," he said.

Dr. Aaron Bauer, one of 20 world herpetology experts, finished up an evaluation (October) in South Africa to complete the Global Reptile Assessment

Prof. Aaron Bauer was 1 of 20 world experts who participated in the evaluation of the reptiles of Central and Southern Africa at a workshop held in South Africa for the IUCN (International Union for Conservation of Nature) (Oct, 2019). This organization established and maintains the Red List of Threatened Species, an authoritative assessment of the status of animals, plants, and fungi.This was the last of a series of workshops held to complete the Global Reptile Assessment (2020).  Dr. Bauer has also participated in similar workshops covering S. Africa, India, and New Caledonia. Read more

Villanova University Biologist Part of Research Team that Discovered How High CO2 Can Create “Shrinking Stems” in Marshes

For many plants, carbon dioxide acts like a steroid: The more they can take in, the bigger they get. Associate professor of Biology Adam Langley, PhD, was part of a research team who discovered something strange happening in marshes. Under higher levels of carbon dioxide, instead of producing bigger stems, marsh plants produced more stems that were noticeably smaller. Read more

Villanova University Researchers Part of Team in Determining the Critical Load of Atmospheric Nitrogen Endangering Northern Alberta Peat Bog Ecosystems

Three Villanova University researchers, part of a team that through a five-year study in Alberta, Canada determined the “critical load”—or recommended maximum amount of nitrogen that can enter the region’s peat bogs through precipitation without causing damage to its ecosystem—have released their findings in an article published June 18 in Ecological Monographs.
