Abstract Radio‐ and acoustic telemetry in three Midwestern lakes demonstrated that common carp, Cyprinus carpio L., aggregate as water temperatures descend below 10 °C. Particularly dense aggregations formed at <5 °C, once located, these could be removed with an efficiency of up to 94% using seine nets. Carp aggregated just the surface ice (approximately 1.5 m) rarely descended warmer waters, which extended down m. Although consistently close shore, their locations not explained by...
Reintroductions are commonly employed to preserve intraspecific biodiversity in fragmented landscapes. However, reintroduced populations frequently smaller and more geographically isolated than native populations. Mixing genetically, divergent sources often proposed attenuate potentially low genetic diversity that may result from small effective population sizes. a possible negative tradeoff for mixing is outbreeding depression hybrid offspring. We examined the consequences of mixed-source...
Abstract Due to the steady decline of waterfowl hunters, several studies have investigated means bolster hunter population. Documented declines in participation are particularly worrisome as funding for conservation North American habitat is dependent on annual purchase Federal Migratory Bird Hunting Conservation Stamps by migratory bird hunters. One method recruiting new hunters through mentoring existing members These mentors serve an important role propagation hunting and continued...
Changes in temperature and precipitation can affect tourist experiences. This study examines how summer park visitation has changed response to extremes. The goals were two-fold. first is introduce a framework the second test it pilot region with four mountainous National Parks. designed compare vulnerability of seasonal shifts combined indicator precipitation. It uniquely considers needed measurements, data required conduct an analysis. goal destinations U.S. Northern Rockies, including...
Using an online survey completed by individuals who hunted deer, waterfowl, upland game, or spring turkey in Nebraska during the 2017–2018 hunting seasons, we applied importance-grid analysis (IGA) and penalty-reward-contrast (PRCA) to examine how activity-related attributes are related satisfaction for each type of activity. Effective response rates small upland-game, surveys were 23%, 16%, 19%, 27%, respectively. Results suggested that among activities, different their sense satisfaction....
Abstract Inundated floodplains, backwaters, and wetlands are important spawning habitats for many freshwater fish. In Midwestern North America areas of northern Europe, the Common Carp Cyprinus carpio Northern Pike Esox lucius inhabit same watersheds perform migrations to interconnected during spring spawn. this study, movement patterns adult from lakes into adjoining were assessed in Minnesota determine how when these species moved, if might be blocked or trapped without disrupting Pike....
Most fishery regulations aim to control angler harvest. Yet, we lack a basic understanding of what actually determines the angler’s decision harvest or release fish caught. We used XGBoost, machine learning algorithm, develop predictive harvest–release model by taking advantage an extensive recreational data set (24 water bodies, 9 years, and 193 523 fish). were able successfully predict outcome for 99% caught in training 96% test set. Unsuccessful predictions mostly attributed predicting...
1. Fish and invertebrate assemblage data collected from 670 stream sites in Minnesota (U.S.A.) were used to calculate concordance across three nested spatial scales (statewide, ecoregion catchment). Predictive taxa richness models, calibrated using the same data, evaluate whether concordant communities exhibited similar trends human-induced loss all scales. Finally, we evaluated strength of relationship between selected environmental variables composition both assemblages at 2. Significant...
Abstract Aim Even successful invaders are abundant only in a fraction of locales they inhabit. One the main challenges invasion ecology is explaining processes that drive these patterns. We investigated recruitment globally invasive fish, common carp ( Cyprinus carpio ), across three ecoregions to determine role environmental characteristics, predatory communities and propagule pressure on process at coarse fine spatial scales. Location Lakes Northern Forest, Temperate Forest Great Plains...
It is important for undergraduate biology students to understand biological phenomena from a systems perspective because it solving world problems related the life sciences (e.g., medical and environmental). Unfortunately, have few opportunities develop skills conceptual knowledge required perspective. Simulated computational models are promising tools help achieve We examined one lesson that uses simulations of model teach about cellular respiration, we report on its effectiveness improve...
Motivations for hunting and fishing extend beyond harvesting game include social, psychological, emotional, physical benefits. We used data from a web-based questionnaire to compare relationships between preferred or activity types, state of residence, motivations hunters anglers across the central United States (U.S.). Exploratory factor analysis yielded four motivation factors: nature, food, challenge. Differences in terms were negligible all factors (ηp2<.01), indicating similarity...
Abstract Recreational fisheries are traditionally managed at local scales, but more effective management could be achieved using a cross‐scale approach. To do this, we must first understand how processes scale up to influence landscape patterns between anglers and resources. We highlight population‐based synchrony methods, used in conjunction with complex‐adaptive‐systems framework, can reveal emergent spatial properties within social‐ecological systems such as recreational fisheries....
ABSTRACT Most state and provincial fish wildlife agencies have access to important information about patterns in sportsperson participation through their license databases. Using transaction data from Nebraska Game Parks Commission's electronic hunting fishing system, we tracked purchases of Nebraska, USA, resident holders 2010 2017. We categorized sportspersons by gender yearly as only (Hunter), (Angler), a combination (Hunter–Angler), or no (Inactive). The probability movement among active...
Recreational fisheries are complex adaptive systems that inherently difficult to manage because of heterogeneous user groups (consumptive vs. nonconsumptive) use patchily distributed resources on the landscape (lakes, rivers, coastlines).There is a need identify which system components can effectively predict and be used nonlinear cross-scale dynamics within these systems.We examine how ecosystem size or water body explain complicated elusive angler-resource in recreational fisheries.Water...
ABSTRACT Declining participation in hunting, especially among young adult hunters, affects the ability of state and federal agencies to achieve goals for wildlife management decreases revenue conservation. For hoping engage diverse audiences hunter recruitment, retention, reactivation (R3) efforts, university settings provide unique advantages: they contain millions adults who are developmentally primed explore new activities, cultivate a social atmosphere where identities can flourish.
