The study of herpetofauna—encompassing reptiles and amphibians—is crucial in understanding and maintaining the health of ecosystems. These creatures play integral roles in food webs, pest control, and nutrient cycling. However, their populations are often overlooked, leading to a lack of awareness about their ecological significance. This gap in understanding contributes to shifting baseline syndrome, a phenomenon where each generation perceives the environment as having fewer species and diminished biodiversity than previous generations. This shift can lead to inadequate conservation efforts and a disconnection from the natural world.

In the Cagle Lab, we recognize the urgency of addressing this issue. Our team is actively contributing to the Duke Forest Community Science project, a comprehensive initiative focused on herpetofauna. We train volunteers and teach students to foster a deeper understanding of these often-overlooked species. By providing hands-on experiences and educational resources, we are cultivating a community of informed citizens who appreciate the role of herpetofauna in our ecosystems.

Our efforts are grounded in a robust framework for long-term data collection and monitoring, designed specifically for some of the world’s most understudied animals. By engaging volunteers and students in herpetofauna research, we aim to build a sustainable model that not only gathers vital data but also raises awareness about the importance of conserving these species. Through this collective effort, we strive to combat shifting baseline syndrome and promote a more inclusive understanding of biodiversity in our environment.

Together, we can ensure that future generations recognize the vital role herpetofauna play in sustaining healthy ecosystems, fostering a deeper connection between people and the natural world.

Herpetofauna Research Methods at the Cagle Lab

In the Cagle Lab, we employ a variety of research methods to gain a comprehensive understanding of herpetofauna diversity and trends in the Duke Forest. One of our key approaches involves long-term monitoring of breeding sites for spotted salamanders (Ambystoma maculatum). By consistently observing these sites over multiple breeding seasons, we can track changes in population dynamics, reproductive success, and habitat use. This longitudinal data is crucial for understanding the health of local populations and their responses to environmental changes, providing valuable insights into the factors influencing their survival.

In addition to breeding site monitoring, we utilize herpetofauna transects equipped with wood and metal coverboards to assess species presence and abundance. Coverboards create microhabitats that attract various reptiles and amphibians, allowing us to easily survey these often elusive creatures. By conducting systematic transects, we can quantify the diversity and distribution of herpetofaunal species within specific areas, enhancing our understanding of their habitat preferences and ecological requirements. This method also allows us to monitor trends over time, identifying potential shifts in species populations in response to environmental changes or habitat alterations.

Another technique employed by the Cagle Lab is acoustic monitoring surveys. By using specialized recording devices, we capture the vocalizations of amphibians, particularly during the breeding season. This non-invasive method enables us to monitor species presence, assess population size, and study calling behaviors without directly disturbing the animals. Acoustic monitoring is particularly beneficial for surveying species that are difficult to observe visually, expanding our understanding of herpetofaunal diversity.

By integrating these diverse research methods, we obtain a more robust and complete understanding of herpetofaunal diversity and trends. Each technique complements the others, allowing us to triangulate data and strengthen our conclusions. This comprehensive approach not only enriches our research findings but also enhances our capacity to inform conservation strategies and promote awareness of these vital, yet often neglected, members of our ecosystems. Through our multifaceted research, we aim to contribute significantly to the knowledge and conservation of herpetofauna, ensuring their continued presence in our natural landscapes.
