Investigating Life in a Tropical Dry Forest In Jalisco, Mexico:
SOBRE Mexico Scholars Present Results of their 2017 Summer Research
 

Presenters:

Cameron Cupp
Samuel Gutierrez
Taylor Henne
Jennifer Magaña
Stacey Meekhof
Lilly Nava

Climate models predict tropical storms will grow stronger as global temperatures rise. The SOBRE Mexico team investigated the response of a tropical dry forest (TDF) ecosystem to Patricia, a category 5 hurricane that struck coastal Jalisco, Mexico in October 2015. In addition, the team investigated parasite/host interactions in the tropical dry forest after the storm.  By knocking down trees and snapping limbs, the storm’s strong winds altered the structure of the forest, which may in turn affect how animals use habitat.  Several techniques were implemented to monitor small vertebrates (amphibians, lizards, turtles) and some of their invertebrate parasites (ticks and kissing bugs) at Estacion de Biologia, Chamela, a TDF reserve struck directly by the hurricane.

The team will present their findings at the October 6th Natural Science Seminar, and at a national research conference in Washington DC later in October.

A Basal Deinonychosaur from James Ross Island, Antarctica and the Biostratigraphy of the Latest Cretaceous, Antarctic Dinosaurs

Dr. Judd Case, Department of Biology, Eastern Washington University

Dr. Case is in his twelfth year at Eastern Washington University having served as the Dean for the College of Science, Health & Engineering/College of STEM for almost 10 years and then as Dean of Special Projects with a major emphasis being the relationship between EWU and the University of Washington around dental and medical education.  He is now full time in the Department of Biology teaching vertebrate zoology, biogeography and hematology.  Additionally, he teaches Oral Histology & Embryology in the RIDE program for the University of Washington’s School of Dentistry and histology for the UW WWAMI Spokane medical program.

He received his Ph.D. in evolutionary biology from University of California, Riverside and his research has centered on vertebrate paleontology to answer questions in the areas of evolution, biogeography and recently on the effects of climate change on the past life in Antarctica.  Dr. Case has extensive Antarctic field experience having conducted nine field seasons in the Antarctic Peninsula, which has been funded by grants from the National Science Foundation.

Dr. Case was honored by the Scientific Committee on Antarctic Research (SCAR) as one of two professors worldwide to receive their prestigious Visiting Professor Award for 2016-17.  This past summer he took his visiting professorship at the Museo de La Plata in Argentina researching new Eocene marsupials from Antarctica as well as new end of the cretaceous dinosaurs from Antarctica.  He presented talks at the Universidad Nacional La Plata and at the Instituto Antartico Argentino in Buenos Aires.

Patterns, Sources, and Impacts of Variations and Trends in the Timing of Seasonal Transitions Over the Coterminous U.S.

Dr. Julio Betancourt, Paleoecologist, USGS

Julio Betancourt is a Senior Scientist with the USGS in Reston VA, and also served for three decades as an Adjunct Professor at the University of Arizona, where he received his Ph.D. in Geosciences with a minor in Ecology & Evolutionary Biology.  He is a research hydrologist and ecologist who studies how climate variability and change affects terrestrial ecosystems at scales critical for understanding ecological and evolutionary processes and informing rational approaches to managing water and other natural resources. A Fellow of the American Geophysical Union and founding co-chair of the USGS Council of Senior Science Advisors, Dr. Betancourt has published two books and 180 peer-reviewed technical papers on a wide diversity of topics.  He has received honors from the American Water Resources Association, the Ecological Society of America and the Geological Society of America, and top awards from the U.S. Department of the Interior and the White House.  He is the founder of  USA National Phenology Network and established the Southern Arizona Bluffelgrass Coordination Center, an NGO that coordinates assessment and mitigation of an African grass invasion in the Sonoran Desert.

Seasonal timing has myriad impacts on plants and animals, biospheric processes, and human systems, and is critical for formulating adaptive responses to both climate variability and change. In the coterminous U.S. [CONUS], the timing of seasonal transitions varies widely from year to year and is also changing directionally, yet the climatic drivers, patterns, and consequences of these variations are not well understood. In his presentation, Betancourt will discuss different interpretations of large-scale drivers, opportunities for long-range forecasting, and implications for continental-scale phenological monitoring in the U.S.

Betancourt will show how day-of-year [DOY] metrics can define spring onset in the CONUS. These DOY metrics exhibit secular trends consistent with both natural variability and greenhouse warming. In the atmosphere, spring onset variations also appear linked to the Pacific North American (PNA) pattern and the Northern Annular Mode (NAM). By contrast, last spring frost, first fall frost, and the duration of the growing season in CONUS poorly tracks common climatic indices, and instead is modulated by the polar vortex.  

Seminars will be added as they are scheduled.  Keep checking back!  If you would like reminders sent to your email for each of these events, please send your request to biology@cwu.edu.

From Bones to Behavior: Using Signs of Injury and Illness to Understand the Lives of Extinct Mammals

Meaghan Wetherell, Associate Director of Institutional Effectiveness, CWU and Adjunct Lecturer, (Ph.D., 2016, University of Oregon) Paleontology, paleopedology, CWU Department of Geology

Fossils are any sign of ancient life (bones, tracks, burrows, and even feces can become fossils), and while an animal’s behavior might not become a fossil, evidence of that behavior can. Forensic science used today can help interpret how animals interacted 30 million years ago – in a sense, like CSI: Oligocene. This presentation will discuss how evidence of illness and injury can be used to piece together a picture of herd structure, lifespan, and defense mechanisms for a group of extinct mammals called oreodonts. In particular, we will cover the abundance of bite marks, infections, bone bruises, and fractures found on the cheekbones of one genus of oreodont, and how such injuries could relate to herd behavior.

Dr. Wetherell graduated with a Ph.D. in paleontology from University of Oregon in summer of 2016, and is currently using her data analysis skills with people rather than fossils as Associate Director of Research for the Institutional Effectiveness Department here at CWU. Paleontologically her current research interests include the convergent evolution of trunks across mammalian families, geographic convergence in sympatric artiodactyls, and spatial modelling  of Pleistocene extinctions
