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...

Effects of vegetation and topography on snowshoe hare relative abundance at the southern range periphery

David C. McNitt, Emily M. Latta, Jordan D. McMahon, Matthew C. Rustand

The Journal of Wildlife Management > 87 > 7 > n/a - n/a

The conservation of snowshoe hares (Lepus americanus) and their habitat is a major focus in the American West, largely because of their importance to the federally threatened Canada lynx (Lynx canadensis). Understanding the habitat relationships of snowshoe hare populations at the southern periphery of their distribution is particularly important because a warming climate is reducing the mesic forests...

Vertical transmission of Renibacterium salmoninarum in cutthroat trout (Oncorhynchus clarkii)

Tawni B. Riepe, Eric R. Fetherman, Brad Neuschwanger, Tracy Davis, more

Journal of Fish Diseases > 46 > 4 > 309 - 319

Vertical transmission of Renibacterium salmoninarum has been well‐documented in anadromous salmonids but not in hatchery‐reared inland trout. We assessed whether the bacterium is vertically transmitted in cutthroat trout (Oncorhynchus clarkii) from a Colorado, USA hatchery, and assessed the rate of transmission from male and female brood fish. Adult brood fish were killed, tested for R. salmoninarum...

Columbian sharp‐tailed grouse female and nest survival in northwestern Colorado

Rachel E. Barker, Anthony D. Apa, R. Scott Lutz

The Journal of Wildlife Management > 87 > 1 > n/a - n/a

Wildlife management and conservation can be challenging when the demography of a focal species is unknown or limited given that fecundity and adult survival influence population growth. The Columbian sharp‐tailed grouse (Tympanuchus phasianellus columbianus) have been reduced to ≤10% of their former range since the early 1900s. We conducted a 3‐year study (2015–2017) across 4 study sites in northwestern...

Survival of Columbian sharp‐tailed grouse chicks and juveniles in northwestern Colorado

Rachel E. Barker, Anthony D. Apa, R. Scott Lutz

The Journal of Wildlife Management > 86 > 8 > n/a - n/a

Chick and juvenile survival are important vital rates for population monitoring and making sound management decisions. These demographics are poorly understood in Columbian sharp‐tailed grouse (Tympanuchus phasianellus columbianus) and survival estimation in the first 2 weeks is particularly challenging to assess. In 2015–2017, we captured 1,219 chicks (1–7 days old) from 156 broods. We marked 625...

Disturbance and valley confinement: Controls on floodplain large wood and organic matter jam deposition in the Colorado Front Range, USA

Molly R. Guiney, Katherine B. Lininger

Earth Surface Processes and Landforms > 47 > 6 > 1371 - 1389

Organic matter dynamics (entrainment, transport, deposition) can influence ecogeomorphic complexity in rivers. However, the depositional controls on downed large wood (LW) and coarse particulate organic matter (CPOM) on floodplains have rarely been assessed. We investigate the influence of different disturbance histories, as well as geomorphology and forest stand density, on the deposition of LW and...

Evaluating the effects of an electric barrier on fish entrainment in an irrigation canal in Colorado

Dan A. Kowalski, Eric I. Gardunio, Chase A. Garvey

River Research and Applications > 38 > 3 > 539 - 547

Entrainment of fish in irrigation canals is a source of mortality for sport and native fishes and can affect populations and species diversity. To reduce entrainment of wild trout, an electric barrier was installed on the South Canal, an irrigation ditch on the Gunnison River in western Colorado, USA. The objective of this study was to evaluate the effectiveness of the barrier by marking fish upstream...

Wildlife visitation at abandoned mines

Timothy A. Armstrong, Chayan Lahiri, Wyatt K. Moran, Brett D. Fuller, more

The Journal of Wildlife Management > 86 > 3 > n/a - n/a

Abandoned mines provide habitat for bats, but their importance to other wildlife is less understood. This descriptive study was designed to answer the following questions with an emphasis on carnivores: are wildlife species other than bats visiting abandoned mines, is wildlife entering abandoned mines, does wildlife visitation at abandoned mines differ seasonally, and does wildlife visitation differ...

Use of predictive distribution models to describe habitat selection by bats in Colorado, USA

Daniel J. Neubaum, Kevin Aagaard

The Journal of Wildlife Management > 86 > 2 > n/a - n/a

Numerous processes operating at landscape scales threaten bats (e.g., habitat loss, disease). Temperate bat species are rarely examined at commensurate scales because of logistical and modeling constraints. Recent modeling approaches now allow for presence‐only datasets, like those often available for bats, to assist with the development of predictive distribution models. We describe the use of presence‐only...

Effects of willow nutrition and morphology on calving success of moose

Forest P. Hayes, Joshua J. Millspaugh, Eric J. Bergman, Ragan M. Callaway, more

The Journal of Wildlife Management > 86 > 2 > n/a - n/a

Across much of North America, populations of moose (Alces alces) are declining because of disease, predation, climate change, and anthropogenic‐driven habitat loss. Contrary to this trend, populations of moose in Colorado, USA, have continued to grow. Studying successful (i.e., persistent or growing) populations of moose can facilitate continued conservation by identifying habitat features critical...
