Mary Jane Rocks the Vote: The Impact of Climate Context on Support for Cannabis Initiatives

Regina Branton, Ronald J. McGauvran

Recent research on direct democracy has focused on the spatial component of voter decision making, finding that when the benefits from a proposed initiative are geographically dependent, support for the initiative in that area increases. However, the existing research has yet to fully specify the factors that lead to benefits for geographically adjacent individuals. Using a unique wave of direct...

Ichneumonid parasitoid wasps from the Early Eocene Green River Formation: five new species and a revision of the known fauna (Hymenoptera, Ichneumonidae)

Tamara Spasojevic, Gavin R. Broad, Andrew M. R. Bennett, Seraina Klopfstein

PalZ > 2018 > 92 > 1 > 35-63

The parasitoid wasp family Ichneumonidae is one of the most species-rich groups of organisms, but its fossil record remains very poorly studied, which impedes inferences of the origin of its diversity. We here describe two new fossil genera and five new species of Ichneumonidae from the Eocene Green River Formation: Carinibus molestus gen. et sp. nov., Ichninsum appendicrassum gen. et sp. nov., Mesoclistus...

Les vertébrés des grès de harding: Ce que Vaillant a pu observer

A. de Ricqlès

Geobios > 1995 > 28 > Supplement 2 > 51-56

Dans une courte note publiée en 1902, Vaillant décrit sommairement, sans le figurer, du tissu osseux cellulairedans des microfragments de vertébrés provenant des grès de Harding (Ordovicien du Colorado). L'examen des préparations microscopiques originales révèle, outre la présence d'Astraspis et d'Eriptychius, celle du “vertébré indéterminé A” de Denison (1967), ce qui confirme le bien fondé des observations...

Behavioral and Demographic Responses of Mule Deer to Energy Development on Winter Range

Joseph M. Northrup, Charles R. Anderson, Brian D. Gerber, George Wittemyer

Wildlife Monographs > 208 > 1 > 1 - 37

Anthropogenic habitat modification is a major driver of global biodiversity loss. In North America, one of the primary sources of habitat modification over the last 2 decades has been exploration for and production of oil and natural gas (hydrocarbon development), which has led to demographic and behavioral impacts to numerous wildlife species. Developing effective measures to mitigate these impacts...

B. B. Martabano, M. Linde Henriksen, C. C. Powell

Equine Veterinary Education > 33 > 1 > 24 - 30

Equine ulcerative keratomycosis is relatively commonly presented to teaching hospitals in North America, with a prevalence from 24 to 86%. Horses in Colorado may have lower risk due to the dry mountain climate, but data are lacking. This study aimed to determine the prevalence of ulcerative keratomycosis amongst horses with ulcerative keratitis presented to Colorado State University Veterinary Teaching...

Quantifying the habitat preferences of the stonefly Pteronarcys californica in Colorado

Dan A. Kowalski, Eric E. Richer

River Research and Applications > 36 > 10 > 2043 - 2050

The salmonfly (Pteronarcys californica) is a large stonefly species that is ecologically important and recreationally significant to anglers in coldwater river systems throughout the western United States. Salmonflies are sensitive to disturbance and pollution and are considered an indicator of quality coldwater stream habitat. They are declining in range and abundance in some river systems and their...

Psychological drivers of risk‐reducing behaviors to limit human–wildlife conflict

Stacy A. Lischka, Tara L. Teel, Heather E. Johnson, Courtney Larson, more

Conservation Biology > 34 > 6 > 1383 - 1392

Conflicts between people and wild animals are increasing globally, often with serious consequences for both. Local regulations or ordinances are frequently used to promote human behaviors that minimize these conflicts (risk‐reducing behaviors), but compliance with ordinances can be highly variable. While efforts to increase compliance could be improved through applications of conservation psychology,...

The Influence of Water Depth on Energy Availability for Ducks

Adam C. Behney

The Journal of Wildlife Management > 84 > 3 > 436 - 447

Habitat management and planning strategies for nonbreeding ducks are focused on providing enough energy to support a desired number of individuals. Therefore, regional estimates of energy availability for nonbreeding ducks are required to determine if sufficient habitat exists for them. I used core sampling to estimate food and energy density in 6 types of water bodies (i.e., actively and passively...

Nest Site Selection Influences Cinnamon Teal Nest Survival in Colorado

Casey M. Setash, William L. Kendall, David Olson

The Journal of Wildlife Management > 84 > 3 > 542 - 552

Nest survival of ducks is partially a function of the spatiotemporal characteristics of the site at which a bird chooses to nest. Nest survival is also a fundamental component of population growth in waterfowl but is relatively unstudied for cinnamon teal (Spatula cyanoptera). We investigated cinnamon teal nest survival in a managed wetland complex in southern Colorado, USA, and assessed nest site...

Fine‐Scale Habitat Selection by Breeding White‐Tailed Ptarmigan in Colorado

Shelley L. Spear, Cameron L. Aldridge, Gregory T. Wann, Clait E. Braun

The Journal of Wildlife Management > 84 > 1 > 172 - 184

Species distributions are influenced by climate and topography in alpine ecosystems, yet resource selection studies of alpine species are uncommon. Basic characteristics of habitats used by alpine‐endemic white‐tailed ptarmigan (Lagopus leucura) have been described to explain foraging behavior, morphology, and survival in many alpine regions; however, there is a lack of information about fine‐scale...

Fire severity and changing composition of forest understory plant communities

Jens T. Stevens, Jesse E. D. Miller, Paula J. Fornwalt

Journal of Vegetation Science > 30 > 6 > 1099 - 1109

Questions Gradients of fire severity in dry conifer forests can be associated with variation in understory floristic composition. Recent work in dry conifer forests in California, USA, has suggested that more severely burned stands contain more thermophilic taxa (those associated with warmer and drier conditions), and that forest disturbance may therefore accelerate floristic shifts already underway...

Late Pleistocene glaciation in the Mosquito Range, Colorado, USA: chronology and climate

Keith A. Brugger, Benjamin Laabs, Alexander Reimers, Noah Bensen

Journal of Quaternary Science > 34 > 3 > 187 - 202

New cosmogenic ¹⁰Be surface exposure ages from 17 moraine boulders in the Mosquito Range of Colorado suggest that glaciers were at their late Pleistocene (Pinedale) maximum extent at ∼21–20 ka, and that ice recession commenced before ∼17 ka. These age limits suggest that the Pinedale Glaciation was synchronous within the Colorado Rocky Mountain region. Locally, the previous (Bull Lake) glaciation...

A new method for restoring ditches in peatlands: ditch filling with fiber bales

Rodney A. Chimner, David J. Cooper, Marcie D. Bidwell, Anthony Culpepper, more

Restoration Ecology > 27 > 1 > 63 - 69

Ditching is a common practice to dewater wetlands, including peatlands, and ditch blocking is a common method for restoring wetlands because substrate is often unavailable for filling the ditches. However, filling has many advantages compared to blocking ditches. Our goal was to test whether ditches could be filled in a Colorado sloping fen (Chattanooga Fen) using bales created from shredded aspen...

A conceptual model for the integration of social and ecological information to understand human-wildlife interactions

Stacy A. Lischka, Tara L. Teel, Heather E. Johnson, Sarah E. Reed, more

Biological Conservation > 2018 > 225 > C > 80-87

There is growing recognition that interdisciplinary approaches that account for both ecological and social processes are necessary to successfully address human-wildlife interactions. However, such approaches are hindered by challenges in aligning data types, communicating across disciplines, and applying social science information to conservation actions. To meet these challenges, we propose a conceptual...

The state of produced water generation and risk for groundwater contamination in Weld County, Colorado

Amanda Shores, Melinda Laituri

Environmental Science and Pollution Research > 2018 > 25 > 30 > 30390- 30400

Natural gas and oil extraction, while meeting much of our current energy demand, also generates large volumes of waste water (“produced water”) that creates risks for groundwater contamination when spilled. Weld County, Colorado, where the majority of extraction occurs in Colorado, was used as a case study to understand how groundwater impacts were related to spill details including volumes spilled,...
