Daily Survival Rates of Grassland Passerines and Associated Weather Variables (1978-2013)

This data set contains daily survival rates from 81 studies of passerine obligate grassland bird species that primarily breed in the United States; patch size information was extracted when available. Temperature and precipitation variables were calculated for the study sites and years the data were collected. The studies we used collected data across the period 1978 to 2013.

Effects of Temperature and Precipitation on Grassland Bird Nesting Success as Mediated by Patch Size

Abstract: Grassland birds are declining faster than any other bird guild across North America. Shrinking ranges and population declines are attributed to widespread habitat loss and increasingly fragmented landscapes of agriculture and other land uses that are misaligned with grassland bird conservation. Concurrent with habitat loss and degradation, temperate grasslands have been disproportionally affected by climate change relative to most other terrestrial biomes. Distributions of grassland birds often correlate with gradients in climate, but few researchers have explored the consequences of weather on the demography of grassland birds inhabiting a range of grassland fragments. To do so, we modeled the effects...

The future demographic niche of a declining grassland bird fails to shift poleward in response to climate change

Abstract (from https://link.springer.com/article/10.1007/s10980-017-0487-x): Context Temperate grasslands and their dependent species are exposed to high variability in weather and climate due to the lack of natural buffers such as forests. Grassland birds are particularly vulnerable to this variability, yet have failed to shift poleward in response to recent climate change like other bird species in North America. However, there have been few studies examining the effect of weather on grassland bird demography and consequent influence of climate change on population persistence and distributional shifts. Objectives The goal of this study was to estimate the vulnerability of Henslow’s Sparrow (Ammodramus henslowii),...

Final Report: Assessing the Vulnerability of Grassland Bird Populations to Climate Change

The Earth is warmer today than it has been during most of the last 11,000 years; as warming trends approach unprecedented levels, there is little doubt that future climate change will have profound effects on species conservation and management. Grassland ecosystems and many grassland-dependent birds are particularly vulnerable to rapid shifts in climate variability and associated changes in drought and extreme weather events. For grassland birds, climate change is likely to exacerbate environmental threats such as habitat loss due to shifting agricultural practices and housing sprawl. Our goal was to identify how certain grassland bird species are sensitive to climate variability and which regions have the highest...
