Method synopsis

Collection and integration of climate variables from multiple databases including temperature, solar radiation, snow metrics, and topographic factors to characterize environmental conditions at study sites.

Synthesized from method descriptions across 3 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Climate mediates the trade-offs associated with phenotypic plasticity in an amphibian polyphenism (2024), Journal of Animal Ecology. Implementations in other papers (listed below) may differ.

1. Climate data acquisition
   Downloaded daily climate estimates from DAYMET database for 1km x 1km gridded cells based on latitude and longitude. Extracted daily maximum and minimum air temperature, precipitation data for entire temporal extent of larval cohorts (1988-2014).
   Quantities: Daily climate data for 1km x 1km grid cells covering study period 1988-2014Duration: 27-year climate dataset (1988-2014)Conditions: Remote sensing data from DAYMET Surface Weather and Climatological database
   Equipment: DAYMET database access, remote sensing data
2. Growing degree day calculation
   Calculated GDD as (Daily max air temperature + Daily min air temperature)/2 - Base temperature (0°C). Negative GDD values assigned zero, daily GDDs summed for given year as metric of summer growing season length. Positive GDDs occur on average from May 30 to October 1 at MCNP.
   Quantities: Daily GDD calculations summed annually for each year 1988-2014Duration: Calculated for each year across 27-year study periodConditions: Base temperature set at 0°C, growing season typically May 30 - October 1
   Equipment: temperature data from DAYMET
3. Snowpack level estimation
   Estimated cumulative snowpack levels in autumn, winter and spring seasons preceding summer sampling season. Snowpack levels served as metric for pond volume and hydroperiod, as ponds are predominantly fed by snowmelt and water levels affect growth and survival.
