R workflow for quantifying inter-population and inter-individual variation in heat stress response mRNA expression profiles in wild brook trout (Salvelinus fontinalis) populations R workflow for quantifying inter-population and inter-individual variation in heat stress response mRNA expression profiles in wild brook trout (Salvelinus fontinalis) populations
Brook trout are a recreationally important fish species that need cold water for survival. The objective of this study was to quantify within- and among-population variability in HSP47 and CIRBP expression in four wild populations of brook trout (Salvelinus fontinalis) to quantify seasonal changes in gene expression. The code release contains a R script for the analysis of brook trout...

R script to simulate point-count data and estimate population trend under various scenarios of changing phenology R script to simulate point-count data and estimate population trend under various scenarios of changing phenology
The script in this code repository simulates point-count data under an example scenario, sets up model input, and runs an N-mixture model with two components of detection (availability and perceptibility) to estimate the population trend. This simulation and analysis were developed to evaluate the consequences of changing spring phenology for estimating population trend of breeding bird

Landsat Compositing of the Ucayali Region in Peru Landsat Compositing of the Ucayali Region in Peru
The USGS User Services, in collaboration with a NASA project, created this compositing workflow that produces Landsat composites for the Ucayali region in Peru. The Ucayali region is located in the heart of the Peruvian Amazon and spans approximately 102,400 square kilometers (39,537 square miles), making it the largest region in the country. The Ucayali experiences significant cloud...
