Dr. Sarah Ivers is a 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 and communication. As part of her teaching portfolio, Dr. Ivers leads field courses (nationally and internationally) and prioritizes authentic experiential learning opportunities in upper-level courses. Her current scholarly focuses involve ecological profiling and biodiversity assessments in Shawnee State Forest and Hanging Rock Preserve, cranial morphometrics of museum specimens, mammalian mortality associated with container debris, and communicating science to a general audience.

Dr. Ivers travels extensively to hike, kayak, and photograph landscapes and wildlife. Trip highlights include documenting polar bears in the wild, chasing the northern lights above the artic circle, kayaking the jaw dropping Milford Sound fjord in New Zealand, and listening to the growls of Tasmanian Devils in Australia. In her own backyard, she enjoys insect collecting and spending time with her Irish Setters. She is an award-winning multidisciplinary artist and in addition to exhibiting her photography, creates scientific illustration and insect assemblages.

  • 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 fly to San Jose and stay the night in Alajuela before traveling through Cloud Forest and then to the station by canal boat. On base, participants are surrounded by native fauna and flora – including monkeys, reptiles and amphibians, birds, and innumerable invertebrates. Students work alongside researchers to conduct marine turtle ovipositional surveys and nesting morning patrols. Depending on specific interests, students may also collect data on resident and migrant birds, tent making bats, plant phenology, climate, neotropical river otters, caimans, large mammals, and great green macaws. The base also manages the only snake ecology and PIT tagging program in the country.

  • Coastal Ecology (1 – 3 credit hours)

Students taking this field course complete terrestrial and marine laboratory exercises in the upper panhandle of Florida (staying at the Port St. Joe Buffer Preserve). The experience begins with a trip to the Georgia Aquarium to see whale sharks, beluga whales, and other marine inhabitants. Once at Port St. Joe, students collectively prepare an ecological profile of a small island, map the distribution of sea urchins in a sea grass bed, visit sites impacted by coastal erosion, catalog mollusk diversity, analyze sand composition and water chemistry, and travel to Wakulla Springs to observe manatees. Past trips highlights include dolphin sightings and sea turtle crawls. Students interesting in this course should first take Marine Biology.

  • Faculty Lead – Ohio Strong Start in Science Initiative, 2024 – Present
  • Coordinator, General Biology and Organismal Biology Programs, 2023 – Present
  • Chair, Campus Tree Care Committee, 2023 – Present
  • Executive Committee Secretary – University Faculty Senate, 2021 – Present
  • Faculty Advisor – Beta Beta Beta Biological Honor Society, Xi Upsilon Chapter, 2021 – Present

My research and scholarly efforts focus on the following:

  • Communication of scientific knowledge via narrative and personal essays
  • Insect and arthropod community assemblages of native plants
  • Ecological profiling of regional preserve and wilderness areas
  • Vertebrate roadway mortality
  • Mammalian mortality in discarded containers
  • Spider community assemblages in urban sites
  • Tritrophic cascades in insect-plant systems
  • Cranial morphometric analysis of museum specimens for investigating metapopulation parameters

Research is conducted in the field and in the laboratory. Data 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. Nearly all research involves undergraduates. Students play a significant role in the experimental design, implementation, and presentation of findings at regional and national conferences.
