Home range and movement metric data of resident and translocated Giant gartersnakes (Thamnophis gigas) in Sacramento, CA, USA, in 2018 to 2021
The dataset consists of two csv files one for home range and net displacement analysis for adult snakes with at least 20 locations collected during the study period and one for the analysis of movement metrics for all adult snakes in the study. The home range data contains the calculated 100 percent and 95 percent minimum convex polygons (MCP) and 95 percent adaptive local convex hull (a-LoCoH) home range estimates, 3 measures of net displacement from the release location of the snake as well as other pertinent information about individual snakes (year included in study, id, treatment group, site, snout to vent length (SVL)). The movement data contains calculations of the following movement metrics: sinuosity, start-to-end distance, and total distance traversed of seasonal movement paths as well as information about individual snakes described above.

Survival data for translocated adults and captive-reared juvenile giant gartersnakes in Sacramento County, California (2018-2021)
공공데이터포털
The dataset consists of two csv files one for adult snakes and one for captive-reared juvenile snakes. The data contains start times (when snakes entered the study) and end times (when snakes died or were censored from the study) for survival analysis. The data also contains general information about the individual snakes (id, snout-vent length, treatment group, whether or not they were translocated), sex (juveniles only since adults were all female), surface activity (and data needed to calculate surface activity), and average distance moved between telemetry resighting. The above information was used as covariates in the survival models.

Capture-Mark-Recapture Data for Giant Gartersnakes in the Sacramento Valley, California from 1999-2016
공공데이터포털
These data are from capture-mark-recapture studies of the giant gartersnake, Thamnophis gigas, in the Sacramento Valley of California, USA from 1999-2016. The data are primarily capture histories (number of captures per year) for 1891 total snakes from 10 sites. Additional data include environmental covariates including precipitation, vegetative cover, and prey abundance from 8 sites from 2011-2016. The files also include R code to reproduce the analyses of giant gartersnake survival presented in Rose et al. (2018) Ecosphere. NOTE: Data are in Supporting Information section of publication (https://esajournals.onlinelibrary.wiley.com/action/downloadSupplement?doi=10.1002%2Fecs2.2384&file=ecs22384-sup-0001-DataS1.zip).
