About

Dr. Sarah Ivers is an associate professor of biology in the Department of Natural Sciences at Shawnee State University. Her areas of expertise include insect-plant relationships, biodiversity, human impacts on organisms and systems and scientific documentation. She leads two field courses (nationally and internationally) and incorporates authentic experiential learning opportunities into upper-level courses. Her current research focuses involve ecological profiling and mammalian diversity assessments in Shawnee State Forest and Hanging Rock Preserve, cranial morphometrics of museum specimens, mammalian mortality associated with container debris, and spider assemblages in abandoned urban systems. Additionally, she prepares scientific illustrations for conferences and other commissions.

Dr. Ivers routinely takes courses in a variety of subjects to extend her knowledge base and skills. Outside of the classroom, she enjoys reading, science fiction, writing, and preparing traditional and digital two-dimensional artworks and insect sculptures. When not indoors, Dr. Ivers spends time traveling, hiking, doing landscape and wildlife photography, collecting insects, and spending time with two gorgeous Irish Setters.

Field Experiences

Costa Rica (3 credit hours)
This immersive field experience takes place at the Caño Palma Biological Field Station within the Barra Del Colorado Wildlife Refuge (Limón Province) of Costa Rica. Students taking this course spend a semester learning about Tican culture and preparing to participate in long-term scientific studies occurring at the field station. Once preparations are completed, students fly to San Jose and stay the night in Alajuela before traveling through Cloud Forest to the station by vehicle and canal boat the following morning. While on base, students are surrounded by native fauna and flora – including three species of monkeys, reptiles and amphibians, numerous bird species, and hundreds of invertebrates. Students work alongside researchers to conduct marine turtle ovipositional surveys and nesting morning patrols. Depending on specific interests, students may also participate in monitoring programs focused on resident and migrant forest birds, climate, shorebirds, tent making bats, plant phenology, neotropical river otters, caimans, large mammals, and great green macaws. The base also houses the only snake ecology and PIT tagging program in the country.

Coastal Ecology (1 credit hour)
Students taking this field course complete terrestrial and marine laboratory investigations while being stationed at the Port St. Joe Buffer Preserve System in the upper panhandle of Florida. The field experience, which lasts nine days, begins with a trip to the Georgia Aquarium to see whale sharks, beluga whales, and numerous other marine inhabitants. Once at the field station, students work collectively to prepare an ecological profile of a small island, map the distribution of sea urchins within a sea grass bed, investigate erosional processes and mollusk diversity, analyze sand composition, conduct water chemistry tests, and travel to Wakulla Springs State Park to observe manatees. Past trips have also involved dolphin sightings and sea turtle crawls. Students interesting in this course should take BIOL 3852 Marine Biology to be eligible to enroll.

Research

Dr. Sarah Ivers’ research and scholarly efforts focus on the following:

• Ecological profiling of regional preserve and wilderness areas
• Tritrophic cascades in insect-plant systems
• Insect and arthropod community assemblages specific to native plants
• Ecological profiling of regional preserve and wilderness areas
• Vertebrate roadway mortality among variable speed limitations
• Causal factors underlying mammalian mortality in discarded containers
• Spider community assemblages in urban sites experiencing succession 
• Cranial morphometric analysis of museum specimens for investigating metapopulation parameters
• Connecting lay populations to the biological sciences through fine arts

Research is conducted in the field and in the laboratory, depending on the specific objectives of individual projects. Data collected from research is shared with agencies aiming to advance environmental stewardship and conservation, including the Canadian Organization for Tropical Education and Rainforest Conversation, Ohio Fish and Wildlife, and Arc of Appalachia. All of Dr. Ivers’ involves undergraduate students, who play a significant role in the experimental design, implementation, and presentation of findings at regional and national conferences. Students interested in the above focuses should contact Dr. Ivers.
