Seth M. Harju, Peter S. Coates, Seth J. Dettenmaier, Jonathan B. Dinkins, Pat J. Jackson, Michael P. Chenaille
2021, Human-Wildlife Interactions (15) 248-269
Over the last half century, common raven (Corvus corax; raven) populations have increased in abundance across much of North America. Ravens are generalist predators known to depredate the eggs and young of several sensitive species. Quantifying raven population increases at multiple spatial scales across North America will help wildlife resource managers...

2021, Incasciences, Revista del Instituto Geológico, Minero y Metalúrgico (1) 53-61
Using a volcanic monitoring data set from Ubinas volcano, we applied a process-based model of pre-eruptive seismic patterns to the 2019 eruptive episode with the goal of identifying possible seismic precursors in order to help forecast future eruptions. This conceptual model, based on geologic processes, is divided into four seismicity...
Evaluating common raven take for greater sage-grouse in Oregon’s Baker County Priority Conservation Area and Great Basin Region
Frank F. Rivera-Milan, Peter S. Coates, Jacqueline B. Cupples, Michael Greenfield, Patrick K. Devers
2021, Human–Wildlife Interactions (15) 544-555
The common raven (Corvus corax; raven) is a nest predator of species of conservation concern, such as the greater sage-grouse (Centrocercus urophasianus). Reducing raven abundance by take requires authorization under the Migratory Bird Treaty Act. To support U.S. Fish and Wildlife Service’s take decisions (e.g., those that authorize killing a...

Common ravens disrupt greater sage-grouse lekking behavior in the Great Basin, USA
Joseph Atkinson, Peter S. Coates, Brianne E. Brussee, Ian A. Dwight, Mark A. Ricca, Pat J. Jackson
2021, Human–Wildlife Interactions (15) 374-390
Expansion of human enterprise has contributed to increased abundance and distribution of common ravens (Corvus corax; ravens) across sagebrush (Artemisia spp.) ecosystems within western North America. Ravens are highly effective nest predators of greater sage-grouse (Centrocercus urophasianus; sage-grouse), a species of high conservation concern. Sage-grouse population trends are estimated...
Homeowners’ willingness to adopt environmentally beneficial landscape practices in an urbanizing watershed
Johanna Stacy, Robert L. Ryan, Allison H. Roy, Anita Milman
2021, Cities and the Environment (14)
Streams in urbanizing watersheds often experience low flows in summer due to increased water use for residential landscaping and decreased base flow as impervious land cover limits aquifer recharge. Environmentally beneficial landscape practices that save water and infiltrate runoff have the potential to provide multiple ecological benefits including reducing...
A seasonal electric barrier blocks invasive adult sea lamprey (Petromyzon marinus) and reduces production of larvae
Nicholas S. Johnson, Brian Snow, Tyler Bruning, Aaron K. Jubar
2021, Journal of Great Lakes Research (47) S310-S319
Sea lamprey (Petromyzon marinus) control is achieved in the Laurentian Great Lakes by applying lamprey-specific pesticides (lampricides) to habitats containing larval sea lamprey. Lampricide treatments cost less and are more effective in watersheds where dams block adult sea lamprey migration and limit...
An adaptive management implementation framework for evaluating supplemental sea lamprey (Petromyzon marinus) controls in the Laurentian Great Lakes
Sean A. Lewandoski, Travis O. Brenden, Michael J. Siefkes, Nicholas S. Johnson
2021, Journal of Great Lakes Research (47) S753-S763
Invasive sea lamprey (Petromyzon marinus) populations in the Laurentian Great Lakes Basin have been suppressed for over 60 years primarily by migration barriers and lamprey-specific pesticides. Improving control outcomes by supplementing barriers and pesticides with additional control strategies has been a...

Secretive marsh bird habitat associations in the Mississippi Flyway: A meta-analysis
K.M. Malone, Elisabeth B. Webb, D. Mengel, L. Kearns, S.W. Matteson, A.E. McKellar
2021, Avian Conservation and Ecology (16)
Secretive marsh birds, including rails and bitterns, have experienced widespread population declines due to the loss of wetland habitat on which they depend. Because of their cryptic behavior, secretive marsh birds are challenging to study and information on their habitat requirements is limited, especially across the full annual cycle. Quantifying...

The black-capped petrel Pterodroma hasitata is an Endangered seabird endemic to the western North Atlantic. Although estimated at ~1000 breeding pairs, only ~100 nests have been located at 2 sites in Haiti and 3 sites in the Dominican Republic. At sea, the species primarily occupies waters of the western Gulf Stream...
Monitoring multi-decadal variations of urban heat island intensity
George Z. Xian, Hua Shi, Kevin Gallo
2021, Conference Paper, 2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS
Urban development and associated land cover transitions alter the thermal and physical properties of the land surface, resulting the temperature in urban area higher than in rural area or urban heat island (UHI). Remote sensing and land cover data is usually used to assess UHI intensity...

2021, Diseases of Aquatic Organisms (147) 149-154
Ranaviruses are emerging pathogens that have caused mortality events in amphibians worldwide. Despite the negative effects of ranaviruses on amphibian populations, monitoring efforts are still lacking in many areas, including in the Prairie Pothole Region (PPR) of North America. Some PPR wetlands in Montana and North Dakota (USA) have...
Can we prove that an undetected species is absent? Evaluating whether brown treesnakes are established on the island of Saipan using surveillance and expert opinion

2021, Management of Biological Invasions (12) 901-926
Detection of invasive species and decisions centered around early detection and rapid response (EDRR) are notorious challenges for decision makers. Detection probability is low for cryptic species, resources are limited, and ecological harm (especially for island ecosystems) can result from...
Wolf use of humanmade objects during pup-rearing
David Edward Ausband
2021, Animal Behavior and Cognition (8) 405-414
Some animals use humanmade objects for building and constructing nests or shelter and even for play. Gray wolves (Canis lupus) gather and use humanmade objects discovered in their natural environment. Gathering humanmade objects is a peculiar behavior particularly when there is no immediately apparent benefit to survival or...

Geographic variation in dispersal of western burrowing owl (Athene cunicularia hypugaea) populations across North America
Alberto Macias-Duarte, Courtney J. Conway
Macias-Duarte, editor(s)
2021, Behavioral Ecology (32) 1339-1351
Dispersal is one of the key elements of species’ metapopulation dynamics and, hence, influences global conservation status. Furthermore, determining the geographic variation in magnitude and direction of dispersal throughout a species’ distribution may expand our understanding of the causes of population declines in species of conservation concern. For instance, western...

Ambystoma opacum (marbled salamander). Atypical nest sites
Joshua M Hall, Brad Glorioso, J Sean Doody
2021, Herpetological Review (52) 595-596
The discovery of inconspicuous nests in secretive species not only expands knowledge but can reveal previously unknown behaviors and ecological consequences of those behaviors. Marbled salamanders exhibit the unusual strategy of laying their eggs terrestrially under cover. Here we report multiple occurrences of A. opacum nesting inside logs, which may...

Kittlitz’s Murrelets (Brachyramphus brevirostris) nest during summer in glaciated or recently deglaciated (post-Wisconsin) landscapes. They forage in adjacent marine waters, especially those influenced by glacial meltwater. Little is known of their movements and distribution outside the breeding season. To identify post-breeding migrations of murrelets, we attached satellite transmitters to...
