State fish and wildlife agencies rely on hunters and anglers (i.e., sportspersons) to fund management actions through revenue generated from license sales and excise taxes on hunting and fishing equipment. There is a need to develop new techniques that bridge the information gap on participation and provide agencies with an understanding of sportspersons at a resolution that can more directly inform efforts to engage sportspersons. Monitoring sportsperson participation using information about their license-purchasing behavior has the potential to reveal important patterns in recruitment (first-time purchase of a hunting or fishing license), retention (continued purchase of licenses across multiple years), and …

Aldo Leopold, famous ecologist and “father” of North American wildlife management, once said, “These are two things that interest me: the relation of people to each other, and the relation of people to land” (Leopold 1947). Ever prescient, Leopold recognized that natural resource management is fundamentally about humans and their relationship with nature well before conservation became an established way of thinking, much less the bedrock of entire professions. Similarly, amid the Green Revolution to increase agricultural production, in part, through widespread use of pesticides, renowned environmentalist and journalist Rachel Carson noted that we are all “a part of nature, …

Record Fledging Count From A Seven-Egg Clutch In The Cooper’S Hawk (Accipiter Cooperii), Robert N. Rosenfield, Sarah A. Sonsthagen, Ann Riddle-Berntsen, Evan Kuhel May 2020

Record Fledging Count From A Seven-Egg Clutch In The Cooper’S Hawk (Accipiter Cooperii), Robert N. Rosenfield, Sarah A. Sonsthagen, Ann Riddle-Berntsen, Evan Kuhel

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Cooper’s Hawks (Accipiter cooperii) typically lay 3–5 eggs per clutch, rarely 6 eggs, and there are 2 accounts of 7-egg clutches and 1 record of a maximum 8-egg clutch for the species. Brood sizes of 3–5 young are common and the previous maximum brood count is 6 young. However, in 2019, we found an urban nest in Stevens Point, Wisconsin, with 7 eggs that resulted in a record high of 7 fledglings. We genetically confirmed that the attending male sired all the offspring and the attending female laid all 7 eggs. Larger body size of the tending adults …

Most state and provincial fish and wildlife agencies have access to important information about patterns in sportsperson participation through their license databases. Using transaction data from Nebraska Game and Parks Commission’s electronic hunting and fishing license system, we tracked license purchases of Nebraska, USA, resident license holders in 2010 through 2017. We categorized sportspersons by gender and yearly purchases as hunting only (Hunter), fishing only (Angler), a combination of hunting and fishing (Hunter–Angler), or no purchases (Inactive). The probability of movement among active sportsperson groups was limited and varied little based on initial group participation. The Angler group had the …

Spatial And Temporal Behavioral Differences Between Angler-Access Types, Derek Kane, Mark A. Kaemingk, Christopher J. Chizinski, Kevin L. Pope Apr 2020

Spatial And Temporal Behavioral Differences Between Angler-Access Types, Derek Kane, Mark A. Kaemingk, Christopher J. Chizinski, Kevin L. Pope

Recreational angler surveys typically collect information on how anglers access a fishery. Yet, it is unclear how this information is useful for fisheries management and conservation. The objective of this study was to compare behavior (e.g., party size, time fished, and numbers of fish released and harvested) of bank and boat anglers, representing two angler-access types. Bank and boat anglers were surveyed across 29 Nebraska waterbodies from April through October, 2007–2017. We documented behavioral differences between bank and boat anglers that varied as a function of waterbody size and season. Patterns of party size, time fished, and numbers of fish …

Weather And Exposure Period Affect Coyote Detection At Camera Traps, Anastasia E. Madsen, Lucia Corral Hurtado, Joseph J. Fontaine Mar 2020

Weather And Exposure Period Affect Coyote Detection At Camera Traps, Anastasia E. Madsen, Lucia Corral Hurtado, Joseph J. Fontaine

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Abstract Camera traps are an increasingly popular means to monitor wildlife populations. However, like other techniques for measuring populations, camera traps are subject to sources of error that may bias population estimates. Past studies accounting for detection error have failed to account for a simple but potentially widely pervasive source of environmental error: weather conditions. Using 5,108,416 photographs from 804 scent‐lured camera traps deployed in western Nebraska, USA, during spring and autumn of 2014 and 2015, we analyzed the relationship between weather conditions (barometric pressure, wind speed, precipitation, and temperature) and coyote (Canis latrans) detection probability. Using binomial …

Mitogenome Of Northern Long-Eared Bat, Sarah Gaughan, Kevin L. Pope, Jeremy A. White, Cliff Lemen, Patricia Freeman Jan 2020

Mitogenome Of Northern Long-Eared Bat, Sarah Gaughan, Kevin L. Pope, Jeremy A. White, Cliff Lemen, Patricia Freeman

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The complete mitogenome of the northern long-eared bat (Myotis septentrionalis) was determined to be 17,362 bp and contained 22 tRNA genes, 2 rRNA genes and one control region. The whole genome base composition was 33.8% GC. Phylogenetic analysis suggests that M. septentrionalis be positioned next to M. auriculus in the Nearctic subclade of the Myotis genus. This complete mitochondrial genome provides essential molecular markers for resolving phylogeny and future conservation efforts.

Use And Expenditures On Public Access Hunting Lands, Lyndsie S. Wszola, Lutz F. Gruber, Erica F. Stuber, Lindsey N. Messinger, Christopher J. Chizinski, Joseph J. Fontaine Jan 2020

The recreational and economic benefits of hunting on traditional permanent public lands are well-established. Increasingly popular “open fields” hunting access programs temporarily open private lands to public hunting through public-private partnerships. Open fields programs have the potential to create public hunting opportunities and economic development in rural communities, but the extent to which open fields programs compare to traditional public lands at providing benefits to hunters and rural communities has not yet been evaluated. We compared hunter use and expenditures on open fields lands and traditional public lands in Nebraska, USA. We used Convolution Likelihood Ecological Abundance Regression, a novel …

Use Of Otolith Chemistry To Assess Recruitment And Habitat Use Of A White Bass Fishery In A Nebraska Reservoir, Matthew A. Perrion, Mark A. Kaemingk, Keith D. Koupal, Casey W. Schoenebeck, Nate A. Bickford Jan 2020

Use Of Otolith Chemistry To Assess Recruitment And Habitat Use Of A White Bass Fishery In A Nebraska Reservoir, Matthew A. Perrion, Mark A. Kaemingk, Keith D. Koupal, Casey W. Schoenebeck, Nate A. Bickford

Managing fisheries that exhibit variable annual recruitment is challenging, and maintenance stockings are often prescribed to minimize interannual population variation. Maintenance stockings are costly and may not be necessary if sufficient natural recruitment is occurring. Therefore, developing tools and techniques that can collectively assess hatching origin and subsequent habitat use of individuals would be valuable. Herein, we aimed to assess the efficacy of otolith chemistry techniques to (1) determine whether there was evidence of natural recruitment within an annually stocked white bass population and (2) examine the potential to describe spatial reservoir use of these age-0 fish. A sample of …

Exit Here: Strategies For Dealing With Aging Dams And Reservoirs, Henry H. Hansen, Emily Forzono, Alisha Grams, Lindsay Ohlman, Christine Ruskamp, Mark A. Pegg, Kevin L. Pope Jan 2020

Aging infrastructure is prevalent throughout the world, but water control management structures, specifically dams, are of growing concern. Dams and their corresponding reservoirs have inherent, but separate, lifespans. The proportion of dams around the world that continue operation beyond their intended lifespans is growing at an alarming rate. Society will not only have to navigate the tradeoffs associated with the deterioration of services provided by reservoirs and dams, but also impending structural failures. Society is nearing a critical pinch point where we will have to decide how to deal with dams and reservoirs at scales that range from a single …
