Using ecoacoustics metrices to track grassland bird richness across landscape gradients

open access: yesEcological Indicators, 2021
Ecoacoustics is an emerging field that allows inferences about biodiversity trends and ecosystem health. Several acoustic indices have been developed for fast, automated assessments of ecosystem condition and are often used to assess changes in species ...

The density and diversity of birds on farmland in West Africa [PDF]

open access: yes, 2008
The area of land farmed in Africa is predicted to double by the year 2050 yet very few African studies have investigated the impact of different farming intensities and regimes on bird communities. This study examined avian species richness and diversity

Risk of Agricultural Practices and Habitat Change to Farmland Birds

open access: yesAvian Conservation and Ecology, 2011
Many common bird species have declined as a result of agricultural intensification and this could be mitigated by organic farming. We paired sites for habitat and geographical location on organic and nonorganic farms in Ontario, Canada to test a priori ...

Microclimate affects the distribution of grassland birds, but not forest birds, in an Alpine environment [PDF]

open access: yesJournal of Ornithology, 2020
Predictions derived from species distribution models (SDMs) are strongly influenced by the spatial scale at which species and environmental data (e.g. climate) are gathered. SDMs of mountain birds usually build on large-scale temperature estimates. However, the topographic complexity of mountain areas could create microclimatic refuges which may alter ...

Estimating direct and indirect effects of habitat structure on nesting field sparrows (Spizella pusilla) using structural equation models

open access: yesFrontiers in Ecology and Evolution, 2023
Due to consistent population declines across the continent, grassland birds have become a guild of high conservation and management interest. Despite a large number of studies investigating grassland bird habitat associations, we know relatively little ...

Winter Bird Population Studies and Project Prairie Birds for Surveying Grassland Birds

open access: yesSoutheastern Naturalist, 2008
We compared 2 survey methods for assessing winter bird communities in temperate grasslands: Winter Bird Population Study surveys are area-searches that have long been used in a variety of habitats whereas Project Prairie Bird surveys employ active-flushing techniques on strip-transects and are intended for use in grasslands.

Grassland bird diversity and abundance in the presence of native and non-native grazers

open access: yesAvian Conservation and Ecology, 2021
Temperate grassland biomes are globally imperiled, and grassland birds are in precipitous decline as a result. The majority of North America's grassland birds breed on rangelands occupied by domestic cattle, but reintroductions of bison to restore ...
