Predicting when animal populations are at risk from roads: An interactive model of road avoidance behavior

TL;DR: In this article, the authors studied the effect of road conditions on the persistence of animal populations and found that road conditions affect animal populations detrimentally in four ways: they decrease habitat amount and quality, enhance mortality due to collisions with vehicles, prevent access to resources on the other side of the road, and subdivide animal populations into smaller and more vulnerable fractions.

TL;DR: Estimating total avian mortality is only a first step in developing an assessment of the biological significance of mortality at communication towers for individual species or groups of species, but can be used to evaluate this source of mortality, develop subsequent per-species mortality estimates, and motivate policy action.
Avian mortality at communication towers in the United States and Canada: which species, how many, and where?

TL;DR: This work constructed a database of mortality by species at towers from available records and calculated the mean proportion of each species killed at towers within aggregated Bird Conservation Regions, and compared these proportions to the estimated populations of these species in the United States and Canada.

TL;DR: In this paper, a fine-filter approach for particular populations or species is mainly useful to monitor the efficiency of coarse-filter approaches for habitats and ecosystems, which is a more proactive and efficient approach than is creating habitat conditions specific to a single endangered species.

Estimated Mortality of Selected Migratory Bird Species from Mowing and Other Mechanical Operations in Canadian Agriculture
TL;DR: In this paper, the authors provided estimates of total mortality rates by mechanical operations for five selected species across Canada, including Horned Lark (Eremophila alpestris), Bobolink (Dolichonyx oryzivorus) and Savannah Sparrow (Passerculus sandwichensis).
