Dataset: Thermoregulation of understory birds in lowland Amazonia

Understanding the capacity for thermoregulation is critical for predicting organismal vulnerability to climate change, especially in lowland tropical rainforests, where warming conditions combine with high humidity and limited elevational or latitudinal refugia. Here, I focused on nine species of ground-foraging insectivorous birds in the genus Myrmoderus, Myrmornis, Hylopezus, Myrmothera, Formicarius, and Sclerurus—sensitive forest specialists characterized by recently documented population declines in both disturbed and undisturbed forests. Using high-resolution data from loggers deployed on birds and their environment, I examined whether and how birds used thermoregulation and whether ambient water provided cooling opportunities. Variation in the rate of temperature change over the diel cycle suggested that all species employed behavioral and physiological thermoregulation, but some patterns differed by species’ phylogenetic relatedness. All species warmed hours before their environm..., , , # Dataset: Thermoregulation of understory birds in lowland Amazonia [https://doi.org/10.5061/dryad.xd2547dr3](https://doi.org/10.5061/dryad.xd2547dr3) ## GENERAL INFORMATION Principal investigator contact information Name: Vitek Jirinec Institution: Integral Ecology Research Center Address: Blue Lake, CA, USA Email: [e-mail] Date of data collection: 2017 to 2019 ## SHARING/ACCESS INFORMATION NA ## DATA & FILE OVERVIEW Please see related data at: [https://doi.org/10.5061/dryad.c866t1g84](https://doi.org/10.5061/dryad.c866t1g84) [https://doi.org/10.5061/dryad.5qfttdz7z](https://doi.org/10.5061/dryad.5qfttdz7z) ### DATA-SPECIFIC INFORMATION FOR: temperature\_lag1\_dataset.csv 1\.
