Mercury and selenium chemical characteristics and speciation data of bird, fish, and earthworm tissues Mercury and selenium chemical characteristics and speciation data of bird, fish, and earthworm tissues

Birds (Clark's grebe, Aechmophorus clarkii; Forster's Tern, Sterna forsteri), fish (Peacock bass, Cichla temensis, Cichla monoculus; Pescada, Plagioscion squamosissimus) and earthworms were analyzed for selenium, total mercury, and methyl mercury concentration and mercury speciation. A Clark's grebe was collected from Lake Berryessa (California, United States) in September 2012. A...

Nest Survival Bias Analysis Nest Survival Bias Analysis

This R script will run one replicate of one scenario used by Weiser (2021) to quantify biases in estimates of nest survival when nests are not found at the beginning of the nesting interval (age 0). The script simulates nest monitoring histories based on input parameters, applies models with or without an age effect to estimate daily survival rates, and calculates nest survival (to the...
