    Shallow gas development and grassland songbirds: the importance of perches 

    Rodgers, Jennifer; Koper, Nicola (Wiley, 2017)
    Grassland bird species have declined more than birds of any other region in North America and industrial development may exert further pressure on these species. We evaluated effects of conventional natural gas infrastructure ...

    Savannah sparrows (Passerculus sandwichensis) nesting close to energy infrastructure alarm call at a lower frequency 

    Antze, Bridget; Koper, Nicola (Taylor and Francis, 2018)
    Many birds rely on alarm calls during nest defense to communicate about risk, but anthropogenic disturbance, including noisy industrial infrastructure, has the potential to disrupt alarm communication. Birds may overcome ...

    Grazing Intensity influences Ground Squirrel and American Badger Habitat Use in Mixed-Grass Prairies 

    Bylo, Lindsey, N.; Koper, Nicola; Molloy, Kelsey (2014)
    Ground squirrel (Spermophilus spp.) and American badger (Taxidea taxus) burrowing activities are ecologically important disturbances that contribute to the heterogeneity of prairie environments. These activities also have ...

    Measuring habitat fragmentation: An evaluation of landscape pattern metrics 

    Wang, Xianli; Blanchet, F. Guillaume; Koper, Nicola (Wiley, 2014)
    Landscape patterns influence a range of ecological processes at multiple spatial scales. Landscape pattern metrics are often used to study the patterns that result from the linear and nonlinear interactions between spatial ...

    Effects of Weather and Land Management on the Western Prairie Fringed-orchid (Platanthera praeclara) at the Northern Limit of its Range in Manitoba, Canada 

    Bleho, Barbara I.; Koper, Nicola; Borkowsky, Christie L.; Hamel, Cary D. (2015)
    The western prairie fringed-orchid is a rare North American orchid restricted to a few remnants of wet to mesic tallgrass prairie. It is federally listed in both Canada and the United States and both countries have developed ...

    The final frontier: Early-stage genetic introgression and hybrid habitat use in the northwestern extent of the Golden-winged Warbler breeding range 

    Moulton, Laurel; Vallender, Rachel; Artuso, Christian; Koper, Nicola (2018)
    Anthropogenic changes to the landscape and climate have resulted in secondary contact between previously allopatric species. This can result in genetic introgression and reverse speciation when closely related species are ...

    Cattle stocking rate and grazing duration effects on songbird nest survival vary by species in mixed-grass prairies 

    Pipher, Emily; Curry, Claire M.; Koper, Nicola (Elsevier, 2016)
    Grassland bird species are declining more quickly than birds of any other biome in North America, but the effects of the most widespread use of native mixed-grass prairies, livestock grazing, on nest survival of songbirds ...

    PHYSICAL FOOTPRINT OF OIL AND GAS INFRASTRUCTURE, NOT ANTHROPOGENIC NOISE, REDUCES NESTING SUCCESS OF SOME GRASSLAND SONGBIRDS 

    Bernath-Plaisted, Jacy; Koper, Nicola (Elsevier, 2016)
    Western North America’s grasslands have undergone a rapid expansion of conventional oil and natural gas development, the effects of which are largely unknown for nesting songbirds. Understanding mechanisms that drive ...

    Is habitat fragmentation bad for biodiversity? 

    Fahrig, Lenore; Arroyo-Rodríguez, Victor; Bennett, Joseph; Boucher Lalonde, Véronique; Cazetta, Eliana; Currie, David J.; Eigenbrod, Felix; Ford, Adam T.; Harrison, Susan P.; Jaeger, Jochen; Koper, Nicola; Martin, Amanda E.; Martin, Jean-Louis; Metzger, Jean Paul; Morrison, Peter; Rhodes, Jonathan R.; Saunders, Denis A.; Simberloff, Dan; Smith, Adam C.; Tischendorf, Lutz; Vellend, Mark; Watling, James I. (Elsevier, 2019)
    In a review of landscape-scale empirical studies, Fahrig (2017a) found that ecological responses to habitat fragmentation per se (fragmentation independent of habitat amount) were usually non-significant (> 70% of responses) ...

    Direct effects of cattle on grassland birds in Canada 

    Bleho, Barbara I.; Machtans, Craig; Koper, Nicola (2014)
    Effects of grazing on grassland birds are generally thought to be indirect, through alteration of vegetation structure; however, livestock can also affect nest survival directly through trampling and other disturbances ...
