Large Birds Of Prey, Policies That Alter Food Availability And Air Traffic: A Risky Mix For Human Safety, Rubén Moreno-Opo, Antoni Margalida
Human–Wildlife Interactions
Raptors are considered to pose one of the greatest aviation bird strike risk. We investigated raptor bird strikes reported at the largest Spanish airport (Adolfo Suárez Madrid Barajas; AS-MB) from 2009 to 2016 to determine the factors contributing to the increased incidences and develop recommendations to mitigate the risks. We hypothesized that increased raptor bird strikes resulted from changes in foraging and dispersal patterns of Iberian Peninsula vultures (Aegypius spp. and Gyps spp.) after 2004-2005. We used information on raptor bird strikes obtained from official databases and published studies, reported incidences of raptor bird strikes and their characteristics (i.e., …
Learning To Live With Wolves: Community-Based Conservation In The Blackfoot Valley Of Montana, Seth M. Wilson, Elizabeth H. Bradley, Gregory A. Neudecker
Learning To Live With Wolves: Community-Based Conservation In The Blackfoot Valley Of Montana, Seth M. Wilson, Elizabeth H. Bradley, Gregory A. Neudecker
Human–Wildlife Interactions
We built on the existing capacity of a nongovernmental organization called the Blackfoot Challenge to proactively address wolf (Canis lupus)-livestock conflicts in the Blackfoot Valley of Montana. Beginning in 2007, wolves started rapidly recolonizing the valley, raising concerns among livestock producers. We built on an existing program to mitigate conflicts associated with an expanding grizzly bear population and worked within the community to build a similar program to reduce wolf conflicts using an integrative, multi-method approach. Efforts to engage the community included one-on-one meetings, workshops, field tours, and regular group meetings as well as opportunities to participate in …

Using Data To Improve Services For Infants With Hearing Loss: Linking Newborn Hearing Screening Records With Early Intervention Records, Maria Gonzalez, Lori Iarossi, Yan Wu, Ying Huang, Kirsten Siegenthaler
Journal of Early Hearing Detection and Intervention
The purpose of this study was to match records of infants with permanent hearing loss from the New York Early Hearing Detection and Intervention Information System (NYEHDI-IS) to records of infants with permanent hearing loss receiving early intervention services from the New York State Early Intervention Program (NYSEIP) to identify areas in the state where hearing screening, diagnostic evaluations and referrals to the NYSEIP were not being made or documented in a timely manner. Data from 2014-2016 NYEHDI-IS and NYEIS information systems were matched using The Link King. There were 274 infants documented in NYEIS Information System as receiving early …
Promoting Critical Thinking In General Biology Courses: The Case Of The White Widow Spider, Joseph S. Wilson
Promoting Critical Thinking In General Biology Courses: The Case Of The White Widow Spider, Joseph S. Wilson
Journal on Empowering Teaching Excellence
It is generally accepted that critical thinking is an important and, likely, essential, component of success in college and beyond. Despite the unanimity, only a low percentage of students in the U.S. can demonstrate critical thinking proficiency on standardized exams. This phenomenon may result from instructors using a reductionist view of critical thinking and focusing on learning processes rather than on evaluation of intellectual resources. In general biology courses, I use a non-threatening, active-learning, group activities to promote critical thinking. For example, students are presented with an email from a member of the community and asked to formulate a response …
Use Of Soil Chemical Analysis To Detect Commercial Wildlife Game Baits, Aaron Haines, Angela Fetterolf, Meta Griffin, Tristan Conrad, Steven Kennedy
Use Of Soil Chemical Analysis To Detect Commercial Wildlife Game Baits, Aaron Haines, Angela Fetterolf, Meta Griffin, Tristan Conrad, Steven Kennedy
Human–Wildlife Interactions
Hunters and poachers often use commercially-available, nutrient-rich baits to attract wildlife game animals. We used atomic absorption spectroscopy and ion selective electrochemical analysis techniques to determine whether two common proprietary baits (Deer Cane and Acorn Rage) would leave detectable chemical signatures in soil (i.e., Na+, Cl-, and Ca+2). Our goal was to evaluate low cost tests which could be replicated by wildlife conservation officers in the field. To complete the evaluation we randomly placed two commercial baits on 3 sites in The Millersville University Biological Preserve in Millersville, PA. We collected soils samples from …
Humans As Prey: Coping With Large Carnivore Attacks Using A Predator-Prey Interaction Perspective, Vincenzo Penteriani, Giulia Bombieri, José María Fedriani, José Vicente López-Bao, Pedro José Garrote, Luca Francesco Russo, María Del Mar Delgado
Humans As Prey: Coping With Large Carnivore Attacks Using A Predator-Prey Interaction Perspective, Vincenzo Penteriani, Giulia Bombieri, José María Fedriani, José Vicente López-Bao, Pedro José Garrote, Luca Francesco Russo, María Del Mar Delgado
Human–Wildlife Interactions
The number of attacks on humans by large carnivores in North America is increasing. A better understanding the factors triggering such attacks is critical to mitigating the risk of future encounters in landscape where humans and large carnivore co-exist. Since 1955, of the 632 attacks on humans by large carnivores, 106 (17%) involved predation. We draw on concepts and empirical evidence from the Predator-Prey Interaction Theory to provide insights into how to reduce predatory attacks and, thus, improve human-large carnivore co-existence. Because large carnivore-caused mortality risks for humans are comparable to those shown by other mammal species in response to …
Community Perceptions Of Grivet Monkey Crop Depredation In The Ethiopian Highlands: Implications For Primate Conservation, Aschalew Alelign, Meheretu Yonas
Community Perceptions Of Grivet Monkey Crop Depredation In The Ethiopian Highlands: Implications For Primate Conservation, Aschalew Alelign, Meheretu Yonas
Human–Wildlife Interactions
Human–primate conflicts in Africa have been increasing due to increased human population growth and the resulting competition for forest resources. The Ethiopian Highlands in northern Ethiopia, home to the grivet monkey (Chlorocebus aethiops), once consisted of large forested areas. This region has been severely denuded and now exhibits only small forest patches remaining at sites with special cultural significance in the immediate vicinity of churches. These forest patches, surrounded by agricultural crops, provide refugia habitat for the grivet monkey. We randomly surveyed 50 villagers living near the Batiero Church Forest, a 45-ha forest patch located in northern Ethiopia, to determine …
Using Resident-Based Hazing Programs To Reduce Human-Coyote Conflicts In Urban Environments, Mary Ann Bonnell, Stewart W. Breck
Using Resident-Based Hazing Programs To Reduce Human-Coyote Conflicts In Urban Environments, Mary Ann Bonnell, Stewart W. Breck
Human–Wildlife Interactions
Abstract The concept of hazing (aversive conditioning) is often promoted as a tool for reducing human-coyote (Canis latrans) conflicts in urban environments. Little scientific evidence exists on the effectiveness of hazing, particularly hazing applied by residents (i.e., community-level hazing). Wildlife professionals question if residents will properly and consistently apply hazing techniques and if hazing impacts coyote behavior over short- and long-term periods. We describe two separate efforts designed to encourage residents to haze coyotes in the Denver Metro Area; a citizen-science program and an open space hazing trial. Both efforts were intended to be management techniques that either …
Evaluating Lethal And Nonlethal Management Options For Urban Coyotes, Stewart W. Breck, Sharon A. Poessel, Mary Ann Bonnell
Evaluating Lethal And Nonlethal Management Options For Urban Coyotes, Stewart W. Breck, Sharon A. Poessel, Mary Ann Bonnell
Human–Wildlife Interactions
Human-coyote conflict in urban environments is a growing issue in cities throughout the United States with the primary problem being the development of problem individuals that are overly bold and aggressive with people and pets. Little research has focused on management options to deal with this conflict. We better define lethal and nonlethal management strategies associated with proactive and reactive management of coyotes with an emphasis on management of problem individuals. We then provide data from research in the Denver Metropolitan Area (DMA) that focused on reactive lethal removal of problem coyotes and reactive nonlethal hazing (i.e., community-level hazing, a …
Coyote Attacks On Humans, 1970-2015: Implications For Reducing The Risks, Rex O. Baker, Robert M. Timm
Coyote Attacks On Humans, 1970-2015: Implications For Reducing The Risks, Rex O. Baker, Robert M. Timm
Human–Wildlife Interactions
Beginning with the emerging pattern of urban and suburban coyotes (Canis latrans) attacking humans in southern California in the late 1970s, we analyzed information from reported attacks to better understand the factors contributing to changes in coyote behavior. We subsequently used updated data collected largely in urban and suburban environments in the United States and Canada during the past 30 years to develop strategies to reduce the risk of attacks. In the 1990s, increased incidents of coyote attacks were reported in states beyond California and in Canadian provinces. We documented 367 attacks on humans by coyotes from 1977 …

Best Management Practices In Counting Urban Black Bears, Jonathan L. Fusaro, Mary M. Conner, Michael R. Conover, Timothy J. Taylor, Marc W. Kenyon Jr.
Human–Wildlife Interactions
DNA-based capture-mark-recapture (CMR) techniques are commonly used to obtain population parameters of black bears (Ursus americanus) in rural and wildland landscapes; however, these techniques have not been implemented in urban clusters (i.e., 2,500 to 50,000 residents). Black bears can readily habituate to urban clusters, and wildlife managers need to monitor and manage these urban bear populations. We modified DNAbased CMR for black bear using hair-snares to take into account the small home ranges of urban bears, urban bear behavior, and human safety within Mammoth Lakes, California, USA. We conducted this study for 3 fi eld seasons in 2010, 2011, and …
Public Geospatial Datasets As An Approach To Maximizing Efficiency In The Collection Of Site Covariates In Wildlife–Vehicle Collision Studies, James A. Vance, Walter H. Smith, Gabrielle L. Smith
Public Geospatial Datasets As An Approach To Maximizing Efficiency In The Collection Of Site Covariates In Wildlife–Vehicle Collision Studies, James A. Vance, Walter H. Smith, Gabrielle L. Smith
Human–Wildlife Interactions
Wildlife–vehicle collisions (WVCs) are a major research focus because of increasing human health and safety concerns and the potential for biological impacts on wildlife. A key component of both understanding the causes of WVCs and designing mitigation measures is the collection and analysis of environmental and roadway data at WVC sites. However, collecting these site data can be logistically challenging and potentially dangerous to researchers. We studied the feasibility and accuracy of using public geospatial datasets, particularly Google Earth and Street View, as an alternative approach to assessing WVC onsite covariates. We randomly selected 50 sites from a larger WVC …
Effects Of Human State Park Visitation Rates On Escape Behavior Of White-Tailed Deer, Nicholas M. Sutton, Edward J. Heske
Effects Of Human State Park Visitation Rates On Escape Behavior Of White-Tailed Deer, Nicholas M. Sutton, Edward J. Heske
Human–Wildlife Interactions
State parks are typically established to preserve natural or native habitats for wildlife while simultaneously providing recreational experiences for humans. However, because of their proximity to urban centers, the level of human visitation associated with state parks may be highly variable. Little information has been published regarding the effect of human visitation levels on wildlife escape behavior in state parks. We evaluated flight initiation distances (FIDs) and buff er distances (i.e., the difference between alert and flight distances) for white-tailed deer (Odocoileus virginianus; deer) from September 2013 to August 2014 at 3 state parks in east-central Illinois with different human …
Positive Bias In Bird Strikes To Engines On Left Side Of Aircraft, Richard A. Dolbeer, William J. Barnes
Positive Bias In Bird Strikes To Engines On Left Side Of Aircraft, Richard A. Dolbeer, William J. Barnes
Human–Wildlife Interactions
Previous studies have indicated more birds collide with communication towers equipped with red warning lights than with towers equipped with lights of shorter wavelengths. We used the U.S. Federal Aviation Administration’s National Wildlife Strike Database to determine if a similar relationship exists for turbine-powered jet aircraft with 2 underwing- or fuselage-mounted engines and bird strikes. We compared bird strikes reported to engine #1 (left side = red lighting) or to engine #2 (right side = green lighting) using chi-square tests (α = 0.05). For both underwing- and fuselage-mounted engines, more (P ≤ 0.04) strikes were reported for engine #1 compared …
Genetic Sequencing Using 16s Rrna For Pathogen Identification In Retropharyngeal Lymph Nodes From Wild Elk, David J. Wilson, Jacqueline P. Kurz
Genetic Sequencing Using 16s Rrna For Pathogen Identification In Retropharyngeal Lymph Nodes From Wild Elk, David J. Wilson, Jacqueline P. Kurz
Human–Wildlife Interactions
Cervical region lymph nodes collected by hunters from 43 wild hunter-harvested elk (Cervus elaphus) in Utah were submitted to the Utah Veterinary Diagnostic Laboratory during fall 2009. We evaluated these lymph nodes as specimens for identification of bacterial pathogens using 16S rRNA genetic sequencing. Thirty-seven bacterial species were identified; each was found in 2 to 30 individual elk. Many common ruminant livestock pathogens were identified in elk; pathogens previously reported in elk were Pasteurella multocida and Streptococcus spp. Cervical region lymph nodes harvested from wild ruminants appear to be acceptable samples for genetic sequencing of bacteria.

Impact Locations And Damage To Civil And Military Rotary-Wing Aircraft From Wildlife Strikes, Brian E. Washburn, Paul J. Cisar, Travis L. Devault
Human–Wildlife Interactions
Rotary-wing aircraft (e.g., helicopters and tilt-wing aircraft) are an important component of all U.S. military services and the U.S. civil aviation industry. Our analyses of wildlife strikes to military rotary-wing aircraft, both within the United States and during overseas deployments, as well as civil helicopters, have shown there are important patterns within wildlife strike data for flight operations conducted on airfields and during off-airfield missions. Birds accounted for 93% of the wildlife strikes where the animal was identified, and mammals (primarily bats) accounted for 7%. Wildlife impacted all parts of civil helicopters and military rotary-wing aircraft during strike events; however, …

Human–Wildlife Interactions
California’s black bear (Ursus americanus) population has tripled over the last 3 decades, causing an increased incidence of human–bear conflicts, many of which now occur in urban areas. Consequently, it is imperative that bear managers have the ability to monitor population parameters in both wildland and urban environments to help manage bears. Capture-mark-recapture (CMR) methods using uniquely typed genetic samples (DNA) collected via hair-snares have been widely used to monitor bears in wildland areas. However, we are unaware of researchers applying this technique to bears occupying urban areas. We implemented a multi-year DNA-based CMR study to compare bear densities between …
Opinion Bridging The Disconnect Between Agencies And Forest Landowners To Manage Deer Impact, David S. Decalesta
Opinion Bridging The Disconnect Between Agencies And Forest Landowners To Manage Deer Impact, David S. Decalesta
Human–Wildlife Interactions
White-tailed deer (Odocoileus virginianus) are managed at 2 levels: by federal, state, or local resource agencies on large, heterogeneous landscapes usually >200 ha; and by individual property owners on smaller (generallyha) and more discrete forestlands. This dichotomy results in a management disconnect: regulations controlling deer hunting (seasons and bag limits) are developed by agencies for landscapes the size of deer management units (DMU) and often are not sufficiently area-specific to meet management needs of individual forest landowners. Resource agencies manage hunters and regulate deer abundance by controlling harvest within DMUs, and they use license and permit fees paid by hunters …

Patterns Of Crop Rading By Wild Ungulates And Elephants In Ramnagar Forest Division, Uttarakhand, Ankur Kumar, Harendra Singh Bargali, Ashish David, Advait Edgaonkar
Human–Wildlife Interactions
Crop raiding is a major form of human–wildlife conflict that not only affects livelihoods of farmers living close to forest areas but also jeopardizes the objective of wildlife conservation. In this study, we report patterns associated with crop raiding based on periodic fi eld inspections of 95 crop fields spread across 16 villages in India. Average raided area of the fi eld was highest in seedling stage (21%). Fields closer to the forest edge incurred higher damage in the seedling (22%) and mature stages (7%) than fields farther from the forest edge, although this was not statistically significant. Guarding was …

Achieving And Maintaining Sustainable White-Tailed Deer Density With Adaptive Management, David S. Decalesta
Human–Wildlife Interactions
A leadership team developed an adaptive management program to reduce deer density and impact on a 29,642-ha forested demonstration area in northwest Pennsylvania incorporating goal setting, monitoring, and communicating with and motivating hunters. We linked reduction of deer density to environmentally sustainable levels with an appeal to the values of hunters (improving deer and habitat quality). The communication program educated and involved hunters as active participants in all phases of the management plan. We monitored deer density, deer impact, deer health, and hunter satisfaction to adjust numbers of permits for harvesting antlerless deer and to improve hunter access and use …
