The National Wildlife Strike Database: A Scientific Foundation To Enhance Aviation Safety, Richard A. Dolbeer, Michael J. Begier, John R. Weller

United States Department of Agriculture Wildlife Services: Staff Publications

The U.S. Federal Aviation Administration's (FAA) National Wildlife Strike Database (NWSD) documents reports of civil aircraft collisions with wildlife in USA. The NWSD has been managed by the Wildlife Services Program of the U.S. Department of Agriculture through an interagency agreement since its inception. Although the NWSD includes about 170,000 reports of civil aircraft collisions with wildlife (97% birds) from 1990-2015 (14,000 in 2015), the overriding focus has been the quality control of data entered for over 90 variables ranging from species and numbers of wildlife struck, location and time of day, phase and height of flight, aircraft type, components …

To Live And Fly In La: Using Bird Strike And Management Program Information To Improve Safety At Airports In The Los Angeles Basin, Todd J. Pitlik, Elizabeth Hermann, Eric Peralta, Brian E. Washburn

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife-aircraft collisions (wildlife strikes) pose a serious safety risk to aircraft. Wildlife strikes can be evaluated at different levels, include efforts to examine these problems at the national, regional, or state level, or for an individual airport. Similarly, wildlife strikes involving individual wildlife species or guilds can be examined at varying scales. Although wildlife strike analyses at the national, regional, or species/guild level are valuable, airport-specific analyses are essential for the effective implementation and evaluation of integrated wildlife damage management programs as these actions are conducted at the airport level. The species that present hazards to safe aircraft operations varies …

Evaluation And Demographic Response Of The Shovelnose Sturgeon Commercial Caviar Fishery In The Wabash River, Jessica L. Thornton

Masters Theses

Shovelnose sturgeon (Scaphirhynchus platorynchus Rafinesque) are considered one of the last commercially viable options for sturgeon roe harvest. Due to the collapse of several marine sturgeon fisheries and the Similarity of Appearances provision which protect shovelnose sturgeon in only a part of their range, the caviar fishery in the Wabash River remains an important point of supply for this lucrative natural resource. In this thesis, I presented an evaluation of the shovelnose sturgeon commercial caviar fishery in the Wabash River. More specifically, I described the demographic response of this population to continued exploitation over a 10-year period. Additionally, I …

Lewis’S Woodpecker Nest Success And Habitat Selection In Cottonwood Floodplain Versus Burned Conifer Forests, William M. Blake

Graduate Student Theses, Dissertations, & Professional Papers

Breeding habitat selection influences reproductive outcomes. Habitat selection may be adaptive and benefit populations, but it can also be maladaptive with negative consequences for populations. Understanding habitat selection and its influence on reproductive success, especially in species of concern, is critical for effective management. Lewis’s Woodpecker (Melanerpes lewis) is a Species of Concern that has experienced national population declines. We studied its abundance and reproductive success in two commonly selected breeding forest types (i.e., cottonwood floodplain and mixed-conifer burned), and nest-site characteristics (nest availability, food availability, and vegetation attributes) that have the potential to yield strong differences in …

Wild Horse Demography: Implications For Sustainable Management Within Economic Constraints, Robert A. Garrott

Human–Wildlife Interactions

Management of wild horse (Equus ferus caballus ) populations on western U.S. rangelands has been a challenge since horses were given legal protection through the passage of the Wild Free-Roaming Horses and Burros Act (WFRHBA) in 1971. Horses have no eff ective predators, and unmanaged populations can double in 4–5 years and triple in 6–8 years. In order to meet the multiple-use paradigm for managing public rangelands, the Bureau of Land Management (BLM) has limited horse population growth through the periodic capture and removal of animals. While the WFRHBA mandates disposal of captured horses through placement into private ownership and …

Of Rats And Men, Thomas S. Walsh

Capstones

This capstone is a data-driven investigation into New York City's rat problem. By using publicly available government data to map rat activity in NYC, I identified several socio-economic variables that correlate with rat populations at the community district, borough, and city-scale. I used these findings (mainly that rat problems are linked to lower incomes) as the basis of an investigation, which includes interviews with residents, experts, and city officials. Prof. Bobby Corrigan, urban rodentologist and formerly with the NYC Department of Health criticizes the city's efforts for the first time on the record.

Fall Field Report, August - November 2017, W. Ross Silcock

Nebraska Bird Review

This fall season will be remembered as the fall with the mega-rarities. There were five, one of which, Pacific Wren, is a first Nebraska record. Based on occurrence dates, Hurricane Irma appears to have influenced the appearance of two of the megas, Black Vulture and Magnificent Frigatebird, neither of which provided opportunities for observers to view them, but both well-documented with photographs. There were an extraordinary TWO sightings of Harris’s Hawk, which together with the presence as of this writing (December 19) of one in northeast Kansas and a view of the species map in eBird strongly suggest a single …

Field trips were led by William Flack, Clem Klaphake, Wayne Mollhoff, Don Paseka, Ross Silcock and T. J. Walker. Locations included Cedar Point Biological Station, Lake Ogallala SRA, various beaches along the shore of Lake McConaughy SRA, Ash Hollow State Historical …

Genomic Data Reveal A Loss Of Diversity In Two Species Of Tuco-Tucos (Genus Ctenomys) Following A Volcanic Eruption, Jeremy L. Hsu, Jeremy Chase Crawford, Mauro N. Tammone, Uma Ramakrishnan, Eileen A. Lacey, Elizabeth A. Hadly

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Marked reductions in population size can trigger corresponding declines in genetic variation. Understanding the precise genetic consequences of such reductions, however, is often challenging due to the absence of robust pre- and post-reduction datasets. Here, we use heterochronous genomic data from samples obtained before and immediately after the 2011 eruption of the Puyehue-Cordón Caulle volcanic complex in Patagonia to explore the genetic impacts of this event on two parapatric species of rodents, the colonial tuco-tuco (Ctenomys sociabilis) and the Patagonian tuco-tuco (C. haigi). Previous analyses using microsatellites revealed no post-eruption changes in genetic variation in C. …

Evaluating The Ecological Status Of The Introduced Nile Monitor (Varanus Niloticus) In Florida: Forecasting Presence And Population Expansion Using Computational Geographic Information Systems, Noah G. Cohen

HCNSO Student Theses and Dissertations

The Nile monitor (Varanus niloticus) is a large, carnivorous lizard that has become a notorious invasive species in Florida, USA. Initially released in the 1980s from the pet trade, the species has since established at least three breeding populations and spread throughout much of southern Florida. While current control efforts have failed to eradicate V. niloticus, it is important to attain a better understanding of its invasive dynamics to guide and inform better control strategies. In this study, available georeferenced records of V. niloticus in Florida were compiled and linked to a habitat classification map to evaluate ecotype preferences. Factored …

A Study Of The Urban Red Fox (Vulpes Vulpes) Population In Baton Rouge, Louisiana Using Social Media, Ahsennur Soysal

LSU Master's Theses

Foxes are timid yet resourceful animals that are integrated into many urban environments. Because they are elusive, collecting information about the number of urban foxes, their diet and spatial distribution, their interactions with the ecological community in their urban habitat, as well as residents’ response to them, is difficult. Involving stakeholders to participate in the data collection on wildlife via citizen science on social media is one way to overcome this complication, while simultaneously engaging residents in the ecology happening around them. Therefore, we used social media as the platform to engage the public to document and map the foxes …

The Utility Of Bioenergetics Modelling In Quantifying Predation Rates Of Marine Apex Predators: Ecological And Fisheries Implications, A. Barnett, M. Braccini, C. L. Dudgeon, N. L. Payne, K. G. Abrantes, M. Sheaves, E. P. Snelling

Fisheries Research Articles

Predators play a crucial role in the structure and function of ecosystems. However, the magnitude of this role is often unclear, particularly for large marine predators, as predation rates are difficult to measure directly. If relevant biotic and abiotic parameters can be obtained, then bioenergetics modelling offers an alternative approach to estimating predation rates, and can provide new insights into ecological processes. We integrate demographic and ecological data for a marine apex predator, the broadnose sevengill shark Notorynchus cepedianus, with energetics data from the literature, to construct a bioenergetics model to quantify predation rates on key fisheries species in …

The North American Quails, Partridges, And Pheasants, Paul A. Johnsgard

Zea E-Books Collection

This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel’s, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly …

First Report Of A Population Of Western Blacknose Dace (Rhinichthys Obtusus) In The Brushy Creek System Of The Black Warrior River Drainage, Alabama, Eric Bauer, Malorie M. Hayes

Southeastern Fishes Council Proceedings

Alabama is home to the southernmost populations of Rhinichthys obtusus, the Western Blacknose Dace. Within Alabama, R. obtusus is found in the Tennessee, Coosa, and Black Warrior River basins, but its presence in the Black Warrior River drainage has been limited. Until now, R. obtusus in the Black Warrior drainage has only been reported as collections of 1 to 4 specimens at a time in the Sipsey Fork drainage. Herein, we report two novel occurrences of R. obtusus in the headwaters of the Brushy Creek system in the Black Warrior River drainage including a singleton and a large population. …

Rehabilitation Of An Injured Golden Eagle (Aquila Chrysaetos): A Case Study, Fida Muhammad Khan, Fakhar-I- Abbas, Abu Ul Hassan Faiz

Journal of Bioresource Management

Habitat destruction and anthropogenic activities cause wild birds to migrate towards urban areas in search of food and sometimes nesting in high-roof buildings, where they are caught by local people using different techniques and are further used for hunting or recreational purposes. An injured Golden Eagle (Aquila chrysaetos) was found entangled in bushes near the vicinity of Balkasar Research Complex, Chakwal, Pakistan. After complete physical examination, a wound on the right wing and closed leg fracture was diagnosed. The successful treatment was done by anti-parasitic and anti-bacterial drugs with careful monitoring. Splint was adjusted after aligning the fractured …

Diet And Habitat Analysis Of Barn Owls (Tyto Alba) Nesting At Ponca State Park, Ann Spilker, Joseph A. Gubanyi

Nebraska Bird Review

In 2015 Barn Owls (Tyto alba) nested on the floor of a grain bin in Ponca State Park, Dixon County. Seven nestlings were observed (Figure 1). It is believed that 6 fledged (one carcass was found on the floor of the bin September 26). Barn Owls were not observed the following spring (Jan Johnson, personal communication). Because there are few records of Barn Owls in the region, we collected data to better understand the Barn Owl nesting in Ponca State Park. Barn Owl prey and their importance to reproductive success has been well documented (Marti et al. 2005; Gubanyi et …

Summer Field Report, June - July 2017, W. Ross Silcock

Nebraska Bird Review

Changes in breeding ranges and numbers of Nebraska breeding birds are the primary focus of a Summer Seasonal Report. Every year there are changes to be noted; this year is no exception. Although most of the phenomena listed below are examples of dispersing individuals without breeding evidence, these often indicate breeding range expansion. White-winged Doves are becoming numerous in southern and western Nebraska, although breeding in far eastern Nebraska was only the 5th report for the state. Chuckwill’s- widow continues to creep westward in the south; the westernmost report to date was of one that crossed the 100-mile gap from …

European Starlings, H. Jeffrey Homan, Ron J. Johnson, James R. Thiele, George M. Linz

Wildlife Damage Management Technical Series

European starlings (Sturnus vulgaris, Figure 1) are an invasive species in the United States. The first recorded release of the birds was in 1890 in New York City’s Central Park. Because starlings easily adapt to a variety of habitats, nest sites and food sources, the birds spread quickly across the country. Today, there are about 150 million starlings in North America. Conflicts between people and starlings occur mostly in agricultural settings. Conflicts can occur during winter in urban and suburban environments, especially in business districts.

Starlings damage apples, blueberries, cherries, figs, grapes, peaches, and strawberries. Besides causing direct losses from …

Herons And Egrets, Michael D. Hoy

Wildlife Damage Management Technical Series

Human-Wildlife Conflicts

Landscapes -- Herons and egrets commonly cause damage at aquaculture facilities and recreational fishing waters where fish are held at high densities. In one study, on average wading birds consumed from 4 to 24 golden shiners per day at minnow production facilities in Arkansas. Great blue herons and great egrets commonly feed at catfish production facilities in Mississippi. The tendency for herons and egrets to congregate in large feeding flocks often leads to extensive loss of fish at aquaculture facilities. Fish-eating birds also can have an impact on intensively managed sport fisheries. Damage occurs when herons and egrets …

Habitat Associations With Small Mammal Communities At Wilson's Creek National Battlefield, Stephanie Anne Ellison

Graduate Theses/Dissertations

The purpose of this study was to aid the National Park Service at Wilson’s Creek National Battlefield with the reported habitat monitoring and management goals through vegetation and wildlife surveys within the park. I provided a description of two major habitat types that are of ecological concern, which included non-native ruderal grasslands and upland deciduous woodlands and forests. I evaluated small mammal communities to determine factors that may affect the detection of individual species and examined habitat associations with occupancy, as small mammals are good indicators of habitat quality. My study highlights the need to manage invasive species such as …

Nesting Success Of The Barn Owl (Tyto Alba) Using Nest Boxes In Southwest Missouri, Robert Grant Dickerson

Graduate Theses/Dissertations

The Barn Owl (Tyto alba) is a medium-sized owl belonging to the family Tytonidae. They raise young within natural cavities and on hard surfaces including nest boxes. The nesting success of Barn Owls, using wooden nest boxes, was studied in southwestern Missouri in 2016. Data were collected on clutch and brood sizes, the numbers of young fledged, and the species and amount of prey found in their regurgitated pellets. Interaction between Barn Owls and Great Horned Owls (Bubo virginianus) was also observed and documented. Nest box occupancy was 30% which is lower than in other studies, however this study included …

A Global Community Effort To Decipher The Unique Biology Of Annual Killifish, Nibia Berois, Graciela Garcia, Rafael O. De Sá

Biology Faculty Publications

Over the past 50 years, annual killifishes arose as alternative model organisms for studies of vertebrate biology. The annual fish offers exceptional advantages for studies of genetics, genomics, developmental biology, population dynamics, ecology, biogeography, and evolution. They inhabit extremely variable freshwater environments in Africa and South America, have a short lifespan and a set of unique and fascinating developmental characteristics. Embryos survive within the dry substrate during the dry season, whereas the adult population dies. Thus, the survival of the populations is entirely dependent on the buried embryos that hatch the next rainy season. Although Old and New World species …
