Journal Article
Rice, E. A., Lewis, T. R., Griffin, R. K., & Grant, P. B. (2022). Heads nods and boat bobs: Behavior of Iguana iguana is affected by environment and boat traffic in riparian tropical forest. Biotropica, 54(4), 820-828. https://doi.org/10.1111/btp.13136

Although frequently studied in captivity, less is known about wild Iguana iguana. Herein behavior of riparian I.iguana was collected alongside climate, vigilance, and boat traffic data. Observations showed boat tourism potentially affects I.iguana ne...

Micro-habitat distribution drives patch quality for sub-tropical rocky plateau amphibians in the northern Western Ghats, India (2018)
Journal Article
Thorpe, C. J., Lewis, T. R., Kulkarni, S., Watve, A., Gaitonde, N., Pryce, D., …Knight, M. E. (2018). Micro-habitat distribution drives patch quality for sub-tropical rocky plateau amphibians in the northern Western Ghats, India. PLoS ONE, 13(3), Article e0194810. https://doi.org/10.1371/journal.pone.0194810

The importance of patch quality for amphibians is frequently overlooked in distribution models. Here we demonstrate that it is highly important for the persistence of endemic and endangered amphibians found in the threatened and fragile ecosystems th...

Artificial egg-strip surveying for detection of pond-breeding newts: Does egg-strip substrate matter? (2017)
Journal Article
Charlton, O., & Lewis, T. (2017). Artificial egg-strip surveying for detection of pond-breeding newts: Does egg-strip substrate matter?. Salamandra, 53(4), 494-500

Survey methods for detecting newts (Salamandridae: Pleurodelinae) in ponds by identifying presence of eggs laid during their aquatic breeding condition are useful and often deployed across various population surveillance activities. Egg-strip surveyi... Read More about Artificial egg-strip surveying for detection of pond-breeding newts: Does egg-strip substrate matter?.

Amphiesma stolatum (striped keelback): Habitat and reproduction (2016)
Journal Article
