Nuisance American Alligators: An Investigation Into Trends And Public Opinion, Cord B. Eversol, Scott E. Henke, Jacob L. Ogdee, David B. Wester, Amos Cooper

Human–Wildlife Interactions

The population rebound of the American alligator (Alligator mississippiensis; hereafter, alligator), with the rapid growth of populations throughout its range, has caused an influx of human–alligator conflicts. We quantified 5,838 nuisance alligator reports from 2000 to 2011 to develop more site-specific strategies of management and to determine where management should be focused to minimize the conflict. We also surveyed the general public’s attitude toward and knowledge of alligators (n = 98) as a technique to better understand human dimensions of nuisance alligator management in Texas. Counties that received the largest numbers of nuisance alligator reports were Jefferson (16%), Fort Bend …

Influence Of Egg Oiling On Colony Presence Of Ring-Billed Gulls, Travis L. Devault, Paige M. Schmidt, Fred E. Pogmore, John Gobeille, Jerrold L. Belant, Thomas W. Seamans Jan 2014

Influence Of Egg Oiling On Colony Presence Of Ring-Billed Gulls, Travis L. Devault, Paige M. Schmidt, Fred E. Pogmore, John Gobeille, Jerrold L. Belant, Thomas W. Seamans

Human–Wildlife Interactions

Egg oiling is a form of management in which bird eggs are coated with mineral or corn oil, preventing gas exchange through the shell and killing embryos. Unlike other nest disturbance techniques, egg oiling reportedly precludes colony abandonment and, thus, can be advantageous when managers wish to limit dispersal within the breeding season to other locations while stabilizing the population or reducing productivity. However, unintended, indirect effects of egg oiling are not well-characterized. We evaluated the influence of egg oiling on ring-billed gulls (Larus delawarensis) within the Lake Champlain basin, Vermont, during the nesting season to determine whether egg oiling …

Integrating Mammalian Hazards With Management At U.S. Civil Airports: A Case Study, Kristin M. Biondi, Jerrold L. Belant, James A. Martin, Travis L. Devault, Guiming Wang

Human–Wildlife Interactions

Wildlife incidents with U.S. civil aircraft cost an estimated $1.4 billion from 1990 to 2010, with mammals 5 times more likely to cause damage than other wildlife. We surveyed 2 general aviation (GA) airports and 6 Part-139 certificated (i.e., certified) airports to assess efficacy of management practices for mammalian species hazardous to aircraft. We obtained information on mammalian species present on airport grounds, types and estimated effectiveness of management techniques, and effort spent on wildlife management. We evaluated management techniques relative to aircraft–wildlife collisions (i.e., incident) frequencies taken from Federal Aviation Administration’s (FAA) National Wildlife Strike Database and species hazard …

Testing Systems Of Avian Perch Deterrents On Electric Power Distribution Poles In Sage-Brush Habitat, James F. Dwyer, Kerrin W. Doloughan

Human–Wildlife Interactions

In Lincoln County, Washington, USA, greater sage-grouse (Centrocercus urophasianus) and Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus) are managed as reintroduced and augmented populations, respectively. Predation by raptors and corvids is a concern, particularly where utility poles may provide hunting perches near leks (i.e., breeding areas). Perch deterrents may offer a mitigating strategy if deterrents reduce the frequency or duration of perching. To investigate the effects of various perch deterrents, we deployed deterrents on 5 power poles retained for use in this study when 33 poles were removed from occupied grouse habitat. We rotated deterrents among poles every 15 to 28 …

Identifying People’S Most Preferred Management Technique For Feral Cats In Hawaii, Cheryl A. Lohr, Christopher A. Lepczyk, Linda J. Cox Jan 2014

Identifying People’S Most Preferred Management Technique For Feral Cats In Hawaii, Cheryl A. Lohr, Christopher A. Lepczyk, Linda J. Cox

Human–Wildlife Interactions

Feral cats (Felis catus) are abundant in many parts of the world and pose a threat to native wildlife. Human–wildlife conflicts regarding how feral cats should be managed have increased recently. In Hawaii, previous research has revealed that most residents would like to see the feral cat abundance reduced, but opinions differ regarding which techniques are acceptable for achieving this. This paper describes an analytical hierarchy process that combines rankings of decision criteria by Hawaii’s residents with expert knowledge of the costs and benefits associated with 7 techniques (live-capture and adoption, live-capture and lethal injection, live-capture and lethal gunshot, trap-neuter-release …

Population Trends Of Resident And Migratory Canada Geese In Relation To Strikes With Civil Aircraft, Richard A. Dolbeer, John L. Seubert, Michael J. Begier Jan 2014

Population Trends Of Resident And Migratory Canada Geese In Relation To Strikes With Civil Aircraft, Richard A. Dolbeer, John L. Seubert, Michael J. Begier

Human–Wildlife Interactions

Canada geese (Branta canadensis) are of particular concern to aviation in the USA because of their large size, flocking behavior, attraction to airports for grazing, and, for the resident population, year-round presence in urban environments. We documented trends in resident and migrant Canada goose populations in North America from 1970 to 2012, and for 1990 to 2012 examined these trends in relation to trends in reported civil aircraft collisions (strikes) with Canada geese. The overall Canada goose population increased 4.5 fold from 1.26 million in 1970 to 5.69 million in 2012. Most of this overall increase was due …

Evaluation Of Eight Repellents In Deterring Eastern Cottontail Herbivory In Connecticut, Scott C. Williams, Michael R. Short Jan 2014

Evaluation Of Eight Repellents In Deterring Eastern Cottontail Herbivory In Connecticut, Scott C. Williams, Michael R. Short

Human–Wildlife Interactions

Herbivory by eastern cottontails (Sylvilagus floridanus) can be the source of significant agricultural, nursery, and managed landscape damage. Where cottontails cannot be managed by lethal means or where trap and release is infeasible, repellents may be a reasonable alternative. We tested 8 different repellent formulations (Bobbex Deer Repellent® Canadian formulation concentrate, Bobbex Deer Repellent® Canadian ready-to-use (RTU), Bobbex-R Animal Repellent® concentrate, Bonide Repels All® concentrate, Bonide Deer & Rabbit Repellent® concentrate, Liquid Fence® Deer & Rabbit Repellent concentrate, Plantskydd® soluble powder, and Rabbit Stopper® RTU) on Johnny jump-ups (Viola tricolor), lettuce (Lactuca sativa), and …

Determination Of Residue Levels Of Alpha-Chloralose In Duck Tissues, David A. Goldade, Randal S. Stahl, John. J. Johnston Jan 2014

Determination Of Residue Levels Of Alpha-Chloralose In Duck Tissues, David A. Goldade, Randal S. Stahl, John. J. Johnston

Human–Wildlife Interactions

Alpha-chloralose (AC) is used to capture nuisance waterfowl so that they can be relocated. Concerns for food safety limit its use prior to or during the waterfowl hunting season. To determine its half-life in tissue, we administered AC to adult male (n = 7) and female (n = 5) mallard ducks (Anas platyrhynchos) via oral gavage. A gel capsule containing 100 μCi of radioactive AC (14C-AC) and sufficient nonlabeled AC to produce a dose of approximately 30 mg/kg was given to each duck.The ducks were euthanized at 2, 6, 10, and 18 hours postdosing …

Effects Of Removal On A Lightly Exploited Coyote Population In Eastern Nevada, Patrick J. Jackson Jan 2014

Effects Of Removal On A Lightly Exploited Coyote Population In Eastern Nevada, Patrick J. Jackson

Human–Wildlife Interactions

Coyote (Canis latrans) removal is a common, yet controversial, management practice to increase game populations throughout the West. I studied the effect of removal on coyote populations in eastern Nevada from 2004 to 2008 and reviewed 27 available publications to determine the level of human exploitation on my study populations. Removals were performed by USDA Wildlife Services (WS) to benefit game populations and involved the use of trapping, neck snaring, and ground and aerial shooting. To determine if the removal had an effect on the coyote populations, I measured 3 parameters: the presence or absence of skewed sex …

Examining Patterns Of Animal–Vehicle Collisions In Alabama, Usa, Xiongwen Chen, Shuhong Wu Jan 2014

Examining Patterns Of Animal–Vehicle Collisions In Alabama, Usa, Xiongwen Chen, Shuhong Wu

Human–Wildlife Interactions

Animal–vehicle collisions (AVCs) cause animal death, human injury, and vehicle damage. Uncovering the general patterns and related ecological processes of AVCs is useful for developing mitigation strategies. We examined some previous patterns about AVCs from records in Alabama during 2001 to 2011. The results confirm that: (1) there was a seasonal pattern, with >50% of AVCs occurring in winter; (2) AVCs occurred most frequently at dawn and dusk in the diurnal pattern; and (3) most AVCs occurred on county highways. However, interstate and federal highways had higher numbers of AVCs per km of road. Counties within metropolitan areas had more …

Soil Quality Manipulation To Reduce Bird Presence At Airports, Theresa K. Johnston, Bruce Branham, Jeffrey Brawn Jan 2014

Soil Quality Manipulation To Reduce Bird Presence At Airports, Theresa K. Johnston, Bruce Branham, Jeffrey Brawn

Human–Wildlife Interactions

Aviation safety is an important concern in wildlife management as bird strikes risk human lives and result in costly damage. Habitat management can decrease bird abundances locally at airports. We tested soil manipulation as a technique to reduce local bird presence by establishing experimental plots with either intact topsoil or “stripped” subsoil with the aim of decreasing foraging substrate for birds. We estimated invertebrate abundance, and observed bird presence from 2006 to 2008. More birds visited topsoil plots (151.5 birds/ ha/hour) than subsoil plots (72.7 birds/ha/hour). Topsoil plots supported a greater biomass of invertebrates than subsoil plots ( = 0.39 …

Efficacy Of Ropel® As A Coyote Repellent, Elizabeth A. Miller, Julie K. Young, Scott Stelting, Bruce A. Kimball Jan 2014

Efficacy Of Ropel® As A Coyote Repellent, Elizabeth A. Miller, Julie K. Young, Scott Stelting, Bruce A. Kimball

Human–Wildlife Interactions

We examined the repellency of a commercially available animal repellent to determine the efficacy of its application to objects that are attractive to coyotes (Canis latrans). Specifically, we aimed to both prevent chewing behavior by coyotes on a nylon-like strapping material, which is used to construct barrier-arresting systems on military airstrips, and determine the ability of the solution to prevent the animals from repeating the undesired behavior. We mixed Ropel® Animal and Rodent Repellent with a liquid latex sticker to form a 2% latex and 98% Ropel solution. We used a 2% latex and 98% water solution as …

First Report Of Satellite Males During Breeding In Leptodactylus Latrans (Amphibia, Anura), Gabriel Laufer, Noelia Gobel, José M. Mautone, María Galán, Rafael O. De Sá Jan 2014

First Report Of Satellite Males During Breeding In Leptodactylus Latrans (Amphibia, Anura), Gabriel Laufer, Noelia Gobel, José M. Mautone, María Galán, Rafael O. De Sá

Biology Faculty Publications

Individual males can adopt alternative mating tactics. The occurrence of satellite males is a common behaviour across anuran taxa (e.g., Lithobates clamitans, Wells, 1977; Anaxyrus cognatus, Krupa, 1989; Dendropsophus ebraccatus, Miyamoto and Cane, 1980; Rhinella crucifer, Forester and Lynken, 1986). Satellite males take peripheral positions to calling males, and adopt alternate mating tactics in an attempt to intercept females that are attracted to calling males (Wells, 2007) to increase their own mating success. Satellite males could have an inexpensive form of mate-locating, avoiding predators, and saving energy (Arak, 1983). Furthermore, this strategy could play an important role in the genetic …

The Taxonomic Status And Geographic Distribution Of The European Hare (Lepus Europaeus Pallas, 1778) In Turkey (Mammalia: Lagomorpha), Yasi̇n Demi̇rbaş, İrfan Albayrak Jan 2014

The Taxonomic Status And Geographic Distribution Of The European Hare (Lepus Europaeus Pallas, 1778) In Turkey (Mammalia: Lagomorpha), Yasi̇n Demi̇rbaş, İrfan Albayrak

Turkish Journal of Zoology

This study was based on 125 specimens of hares collected from 61 different localities in Turkey between 2006 and 2010. We present diagnostic characters, pelage coloration, external, cranial and phallic measurements, skull and phallus features, hair structure, and collection localities of hares from Turkey. Additionally, we analyze morphometric variations of 5 regional populations according to the physiography/orography of the study area. Among the morphometric variables, 10 characters (weight, tail length, basal length, condylobasal length, rostral breadth, height of braincase, foramen incisiva length, occipitonasal length, profile length, and mandible length) are found to be significantly different between the populations (ANOVA, P < 0.01). Principal component analysis of 22 morphometric measurements is performed, and 71.56% of total variance is explained through 5 principle components. The Thracian specimen is distinguished from other populations on the first 2 canonical discriminant functions and the cluster dendrogram. The hair structure, as examined by scanning electron microscope, is found to be flattened and imbricate. Our Anatolian specimens are discussed at the subspecies level, comparing them to the relevant literature, and it is concluded that Lepus europaeus in Anatolia is represented by only one subspecies, Lepus europaeus syriacus.

Selective Predation On Common Voles By Tawny Owls And Long-Eared Owls In Winter And Spring, Linas Balciauskas, Laima Balciauskiene

Turkish Journal of Zoology

We studied size preferences of Tawny (Strix aluco) and Long-eared (Asio otus) Owls preying on common voles (Microtus arvalis) in the winter and spring seasons in Central Lithuania. Regression equations were used for body mass estimations. We found that both A. otus and S. aluco preferred larger M. arvalis than the average available in the population (the average body mass of predated individuals was 21.45 ± 0.12 g compared to 16.42 ± 0.16 g of snap-trapped individuals). Irrespective of the owl species, most of the predated Microtus voles were adults. In S. aluco prey, the winter proportion of young voles …

Assessment Of Range, Habitat Use, And Diel Movement Of Flathead Catfish (Pylodictis Olivaris) In The Wabash River Using Ultrasonic Telemetry, Sarah Mary Huck Jan 2014

Assessment Of Range, Habitat Use, And Diel Movement Of Flathead Catfish (Pylodictis Olivaris) In The Wabash River Using Ultrasonic Telemetry, Sarah Mary Huck

Masters Theses

Flathead Catfish (Pylodictis olivaris) are one of the most targeted species for recreational and commercial fishing within the Mississippi River Basin. With heavy harvest pressure placed on many populations, proper management is crucial; however, the species range, habitat requirements, and diel movement patterns have rarely been investigated in free flowing rivers. Therefore, I used ultrasonic telemetry with active tracking to monitor movement and habitat use of 44 Flathead Catfish from August 2012 to December 2013 in the lower 280 km of the Wabash River. This system is ideal to evaluate broad and fine scale movement of Flathead Catfish …
