description: Data Overview

Chiropterans (bats) are an incredibly diverse and abundant taxa that provide vital ecosystem functions in a range of different climates (Adams and Pedersen 2013). Often linked with metabolic rate, evaporative water loss (EWL) is the measured rate of the combined respiratory and cutaneous water loss in an individual (Muñoz-Garcia et al. 2022). Regulation of EWL is crucial for survival in harsh climates (e.g. deserts) and has been linked to the often fatal white-nose syndrome (Muñoz-Garcia et al. 2022; McGuire, Mayberry, and Willis 2017). Information on EWL in bats is somewhat limited and can widely vary depending on temperature, body size, humidity, and activity level. This dataset compiles the existing values to understand the variance of EWL across bat species.

When necessary, units were changed from originally reported values to match the units reported in this dataset. If multiple EWL values for a single species within the same study were available, the measurement closest to a baseline 10°C ambient temperature and above 30°C body temperature (to avoid measurements in a torpor state) was selected.

 

Literature Search Protocol

Searches were conducted on Google Scholar using search terms “evaporative water loss,” “EWL,” or “TEWL” accompanied with the specification of “in bats” or “in Chiroptera.” The complete literature search was conducted by a single individual over one week in February 2024. Two small previously compiled datasets were used to form a subset of this data (Muñoz-Garcia et al. 2022; 2016).

 

Metadata Qualities

Common Name – The commonly used name as stated on the IUCN Red List or GBIF.

Accepted Name – The currently accepted scientific binomial name of the species.

Recorded Name – The scientific name used to refer to the species within the original study.

Body Temp (°C) – The average body temperature of the bat when EWL measurement was taken, described in degrees Celsius. Reported when available.

Ambient Temp (°C) – The average ambient temperature when the individuals were measured for EWL, described in degrees Celsius. Reported when available.

Body Mass (g) – The average body mass of individuals measured for EWL, described in grams.

EWL (g/h) – Evaporative Water Loss (EWL) value stated as a rate of grams of water lost per hour.

Method – The method of EWL data collection and calculation used in the original study.
