Arena trial breach attempts and morphometric data of brown treesnakes and rats, Guam, 2019-2020

There are two datasets included in this entry. The "morph" dataset contains 6 columns of data on brown treesnakes and rats collected prior to and during arena trials for trialing fencing material for multispecies barrier construction. The "trials" dataset includes 25 columns of brown treesnake and rat data collected prior to, during, and after arena trials. There are four data files associated with this data release. They include "BTS_Breach Attempts_29Jun2020.csv" which describes data associated with attempts by brown treesnakes to escape the fence arena' "BTS_Morph_29Jun2020.CSV", which describes morphometrics of captured and trialed snakes; "Rats_Breach Attempts_29Jun2020.csv", which describes attempts to breach...

Brown Treesnake Mortality Habitat Management Unit Guam 2019

The dataset contains 16 columns of data collected on invasive Brown Treesnakes (Boiga irregularis) at a study site known as the Habitat Management Unit (HMU) in northern Guam. Snakes were fitted with radio-transmitters and teams of 2-4 biologist listened for signals from transmitters every seven days to determine if snakes were alive or dead. Survival data was then modeled in Program MARK to assess the effect of aerially applied toxic baits on snake mortality, including the effect of snake size covariates. In addition, this dataset contains snake capture information from reference sites on Guam that was used to demonstrate that our sample was representative of the size distribution in limestone forest habitat on...
