Camera Trap Survey Suggests Forestry And Prescribed Burns Attract Wildlife, But May Not Enhance Diversity, Melissa S. Vilgats, Ryan Ott, Stephanie S. Coster

Virginia Journal of Science

This study explored whether habitat management techniques such as forest thinning and burning promoted biodiversity. Fifteen camera trap stations were established at Fort A.P. Hill in Bowling Green, VA across forest stands with low, medium, and high basal area. Camera traps were deployed for a total of 532 trap nights, and trap success and species diversity were calculated using Shannon’s index. At each site, the distance to trafficable roadways and water sources, vegetation composition, and the percent groundcover, canopy cover, and understory were measured. The cameras captured nine species and recorded a total of 398 trap events. Linear regression was …

Species distributions are influenced by processes occurring at multiple spatial scales. It is therefore insufficient to model species distribution at a single geographic scale, as this does not provide the necessary understanding of determining factors. Instead, multiple approaches are needed, each differing in spatial extent, grain, and research objective. Here, we present the first attempt to model continent-wide great ape density distribution. We used site-level estimates of African great ape abundance to (1) identify socioeconomic and environmental factors that drive densities at the continental scale, and (2) predict range-wide great ape density. We collated great ape abundance estimates from 156 …

Free-Ranging And Feral Cats, Alex Dutcher, Kyle Pias, Grant Sizemore, Stephen M. Vantassel

Wildlife Damage Management Technical Series

Domestic cats (Felis catus) are a common household pet in the United States, with an estimated 25.4% of households owning cats (American Veterinary Medical Association 2018). While an increasing number of cat owners keep their pet cats exclusively indoors, a portion of society maintains that domestic cats are entitled to a free-ranging lifestyle and may even consider unowned domestic cats to be wildlife. Although wildlife managers recognize the beliefs of many concerned stakeholders, including advocates who use strong emotional appeals on behalf of cats, it remains that free-ranging and feral domestic cats are an invasive species spread by humans (Lowe …

In summer 2020, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was detected on mink farms in Utah. An interagency One Health response was initiated to assess the extent of the outbreak and included sampling animals from on or near affected mink farms and testing them for SARS-CoV-2 and non-SARS coronaviruses. Among the 365 animals sampled, including domestic cats, mink, rodents, raccoons, and skunks, 261 (72%) of the animals harbored at least one coronavirus. Among the samples that could be further characterized, 127 alphacoronaviruses and 88 betacoronaviruses (including 74 detections of SARS-CoV-2 in mink) were identified. Moreover, at least 10% (n …

Variations, Validations, Degradations, And Noninvasive Determination Of Pregnancy Using Fecal Steroid Metabolites In Free-Ranging Pronghorn, Cole A. Bleke, Eric M. Gese, Susannah S. French

United States Department of Agriculture Wildlife Services: Staff Publications

Pregnancy status is a key parameter used to assess reproductive performance of a species as it represents a starting point for measuring vital rates. Vital rates allow managers to determine trends in populations such as neonate survival and recruitment; two important factors in ungulate population growth rates. Techniques to determine pregnancy have generally involved capture and restraint of the animal to obtain blood samples for determining serum hormone levels. Non-invasive pregnancy assessment, via feces, eliminates any hazards between handler and animal, as well as removes handling-induced physiological biases. Using noninvasive fecal sampling, we conducted hormone validations, investigated pregnancy rates, and …

With rates of psychiatric illnesses such as depression continuing to rise, additional preclinical models are needed to facilitate translational neuroscience research. In the current study, the raccoon (Procyon lotor) was investigated due to its similarities with primate brains, including comparable proportional neuronal densities, cortical magnification of the forepaw area, and cortical gyrification. Specifically, we report on the cytoarchitectural characteristics of raccoons profiled as high, intermediate, or low solvers in a multiaccess problem-solving task. Isotropic fractionation indicated that high-solvers had significantly more cells in the hippocampus (HC) than the other solving groups; further, a nonsignificant trend suggested that this …

Satellite-Detected Ammonia Changes In The United States: Natural Or Anthropogenic Impacts, Yaqian He, Rongting Xu, Stephen A. Prior, Di Yang, Anni Yang, Jian Chen

United States Department of Agriculture Wildlife Services: Staff Publications

Ammonia (NH3) is the most abundant alkaline component and can react with atmospheric acidic species to form aerosols that can lead to numerous environmental and health issues. Increasing atmospheric NH3 over agricultural regions in the US has been documented. However, spatiotemporal changes of NH3 concentrations over the entire US are still not thoroughly understood, and the factors that drive these changes remain unknown. Herein, we applied the Atmospheric Infrared Sounder (AIRS) monthly NH3 dataset to explore spatiotemporal changes in atmospheric NH3 and the empirical relationships with synthetic N fertilizer application, livestock manure production, and climate factors across the entire US …

Adaptation Of An Artificial Bait To An Automated Aerial Delivery System For Landscape-Scale Brown Treesnake Suppression, Rafael A. Garcia, Thomas W. Mcauliffe, Lorelie P. Bumanlag, Shane R. Siers, Bruce A. Kimball

United States Department of Agriculture Wildlife Services: Staff Publications

Dead neonatal mice are currently used as bait for delivery of toxin to invasive brown treesnakes (Boiga irregularis) on Guam; once deployed in the field the mice are highly attractive to the snakes but only for about four days. An artificial bait containing a mixture of fats mimicking those in skin of the mice is also highly attractive to the snakes and remains attractive 2–3 times longer. The artificial bait, however, costs more than the mice, and is more difficult to attach to the capsules of a novel aerial bait delivery system. This paper describes a reformulation of the bait …

Movement, Space-Use And Resource Preferences Of European Golden Jackals In Human-Dominated Landscapes: Insights From A Telemetry Study, Skye Fenton, Paul R. Moorcroft, Duško Ćirović, József Lanszki, Miklós Heltai, Francesca Cagnacci, Stewart Breck, Neda Bogdanović, Ilija Pantelić, Kornél Ács, Nathan Ranc

United States Department of Agriculture Wildlife Services: Staff Publications

During the last half-century, the distribution of golden jackals (Canis aureus) has rapidly increased throughout Europe. Today, golden jackals are thriving in human-dominated landscapes across Southeastern and Central Europe. Most studies on golden jackals have focused on large-scale distribution patterns; to date, little is known about the species’ fine-scale spatial ecology. In this study, we analyzed the movement behavior, space-use and resource selection of six golden jackals fitted with GPS-GSM collars in two study areas in Hungary and Serbia. Two of the jackals were a breeding pair. We found that home range size averaged 11.2 km² (90% …

Effects Of Translocation On Survival Of Nuisance Bears, Javan Bauder, D. Ruid, N. M. Roberts, B. Kohn, M. L. Allen

United States Department of Agriculture Wildlife Services: Staff Publications

Effective mitigation of human–wildlife conflict should aim to reduce conflicts while also minimizing wildlife mortality. Translocation is often used to mitigate human–wildlife conflict but translocated individuals may have reduced survival, which could negatively affect population growth and social acceptance of translocation as a management tool. Yet, non-translocated nuisance individuals may also have low survival due to inherent risks associated with nuisance behavior. We used a 38-year dataset of 1233 marked and translocated nuisance American black bears (Ursus americanus) as a model system with which to evaluate the impacts of translocation on nuisance bear survival. We used multi-state mark-recapture models to …

Threading The Needle: How Humans Influence Predator–Prey Spatiotemporal Interactions In A Multiple-Predator System, Asia Murphy, Duane R. Diefenbach, Mark Ternent, Matt Lovallo, David Miller

United States Department of Agriculture Wildlife Services: Staff Publications

Perceived predation risk and the resulting antipredator behaviour varies across space, time and predator identity. Communities with multiple predators that interact and differ in their use of space, time of activity and hunting mode create a complex landscape for prey to avoid predation. Anthropogenic presence and disturbance have the potential to shift interactions among predators and prey and the where and when encounters occur. We examined how white-tailed deer Odocoileus virginianus fawn spatiotemporal antipredator behaviour differed along an anthropogenic disturbance gradient that had black bears Ursus americanus, coyotes Canis latrans, bobcats Lynx rufus and humans present. We quantified (a) spatial …

How Birds During Migration Maintain (Oxidative) Balance, Scott R. Mcwilliams, Wales A. Carter, Clara Cooper-Mullin, Kristen J. Demoranville, Abigail E. Frawley, Barbara J. Pierce, Megan Skrip

Biology Faculty Publications

Animals dynamically adjust their physiology and behavior to survive in changing environments, and seasonal migration is one life stage that demonstrates these dynamic adjustments. As birds migrate between breeding and wintering areas, they incur physiological demands that challenge their antioxidant system. Migrating birds presumably respond to these oxidative challenges by up-regulating protective endogenous systems or accumulating dietary antioxidants at stopover sites, although our understanding of the pre-migration preparations and mid-migration responses of birds to such oxidative challenges is as yet incomplete. Here we review evidence from field and captive-bird studies that address the following questions: (1) Do migratory birds build …

Predictors Of Marine Genetic Structure In The Indo-Australian Archipelago, Udhi E. Hernawan, Paul S. Lavery, Gary A. Kendrick, Kor-Jent Van Dijk, Yaya I. Ulumuddin, Teddy Triandiza, Kathryn M. Mcmahon

Research outputs 2014 to 2021

The spatial genetic structure of marine organisms is related to dispersal and life-history traits, historical processes, current oceanographic connectivity and habitat features. Here, we assessed the relative importance of these factors for the genetic structure of a broad range of marine species in the Indo Australian Archipelago (IAA). We collated published data on 99 marine species from eight taxonomic groups (ascidians, fishes, molluscs, crustaceans, echinoderms, corals, reptiles, and marine plants) and used generalized linear models (GLMs) to estimate the best predictors of genetic structure. Genetic structure was characterized by FST and the number of genetic clusters over the study area. …

Parasitoids (Hymenoptera: Chalcidoidea) Of The White Peach Scale, Pseudaulacaspis Pentagona (Targioni-Tozzetti) (Hemiptera: Diaspididae) On Prunus Salicina Lindl. (Rosales: Rosaceae) In South Korea, Soo-Jung Suh

Insecta Mundi

Four aphelinid and one encyrtid parasitoid species (Hymenoptera: Chalcidoidea) were collected from Pseudaulacaspis pentagona (Targioni-Tozzetti) infesting twigs and stems of Japanese plum tree (Prunus salicina Lindl.) in a survey conducted in 2020 in South Korea. These were identified as Aphytis proclia (Walker), Encarsia berlesei (Howard), Marietta carnesi (Howard), Pteroptrix orientalis (Silvestri) (Aphelinidae) and Arrhenophagus chionaspidis Aurivillius (Encyrtidae). In this paper, the list of parasitoid species of P. pentagona that occur on Japanese plum trees in South Korea is updated and a brief diagnosis and photographs of each species are provided.

Different mating systems are expected to affect the extent and direction of hybridization. Due to the different levels of sexual conflict, the weak inbreeder/strong outbreeder (WISO) hypothesis predicts that gametes from self-incompatible (SI) species should outcompete gametes from self-compatible (SC) ones. However, other factors such as timing of selfing and unilateral incompatibilities may also play a role on the direction of hybridization. In addition, differential mating opportunities provided by different mating systems are also expected to affect the direction of introgression in hybrid zones involving outcrossers and selfers. Here, we explored these hypotheses with a unique case of recent hybridization …

Global Population Divergence Of A Cosmopolian Desert Plant, Victor Ryan Alfaro

Biology ETDs

Genetic and phenotypic variation can have different patterns within a species if it has populations with contrasting histories. Populations can have discrete differences that are shaped by different evolutionary scenarios, but within each population, range, or region, traits and association with fitness can also be affected by both edaphic and landscape variation. For my dissertation, I surveyed and experimentally analyzed variation and adaptive potential in Sahara mustard (Brassica tournefortii), a desert annual that has endemic, invasive, and agricultural populations in Africa, Asia, and the Americas. Although my multi-trait analysis generated complex results, my findings can be applied to …

Recruitment Patterns Of The Fouling Community On Eelgrass In Long Island Sound, Diana Lancaster

Department of Marine Sciences

Abstract The seagrass Zostera marina (eelgrass) is typically found in shallow protected areas of portions of eastern Long Island Sound (LIS). Although the species and its associated ecosystem have been well studied in many places, work in LIS has been limited. A field study was conducted to assess the fouling communities associated with eelgrass beds around Pine Island, in eastern LIS. Samples were collected from four sites between July and October, 2011. A total of 15 species of fouling organisms were found on eelgrass leaves throughout the study period. Recruitment patterns varied spatially and temporally. Differences in the composition of …

Mitonuclear Mismatch Is Associated With Increased Male Frequency, Outcrossing, And Male Sperm Size In Experimentally-Evolved C. Elegans, Brent William Bever

Dissertations and Theses

We provide the first controlled study of how male frequencies and rates of outcrossing evolve in response to mitonuclear mismatch by allowing replicate lineages of C. elegans nematodes containing either mitochondrial or nuclear mutations of electron transport chain (ETC) genes to evolve under three sexual systems: facultatively outcrossing (wildtype), obligately selfing, and obligately outcrossing. In partial support of a tenet of the mitonuclear sex hypothesis, which predicts that outcrossing will be favored in cases of mitonuclear mismatch, we found evolution of increased male frequency in at least one replicate line of all four ETC mutant backgrounds tested--nuclear isp-1, mitochondrial …

Kelp Morphology And Herbivory Are Maintained Across Latitude Despite Geographic Shift In Kelp-Wounding Herbivores, Nicholas P. Burnett, Eric J. Armstrong, Rosemary Romero, Charlotte C. Runzel, Richelle L. Tanner

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Herbivores can drastically alter the morphology of macroalgae by directly consuming tissue and by inflicting structural wounds. Wounds can result in large amounts of tissue breaking away from macroalgae, amplifying the damage initially caused by herbivores. Herbivores that commonly wound macroalgae often occur over only a portion of a macroalga’s lifespan or geographic range. However, we know little about the influence of these periodic or regional occurrences of herbivores on the large-scale seasonal and geographical patterns of macroalgal morphology. We used the intertidal kelp Egregia menziesii to investigate how the kelp’s morphology and the prevalence of two prominent kelp-wounding herbivores …

Use Of Soapweed Yucca (Yucca Glauca) By Rodents And Other Vertebrates In Western Nebraska, Michael L. Rohde, Keith Geluso, Carter Kruse, Mary J. Harner

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Soapweed Yucca (Yucca glauca) is a conspicuous and common shrub in the Great Plains of North America, characterized by tall woody flower stalks, large flowers and seed pods, and dense masses of ground-level evergreen leaves. These plant structures can provide a variety of resources or functions to animals. In general, studies focus on single species associated with Y. glauca. We examined three groups of vertebrates that interacted with Y. glauca and the functions this plant provided for organisms in western Nebraska. We experimentally examined small mammals in areas with and without Y. glauca, and we descriptively …

Native Plant Focused Publications

The Great Plains of North America encompass approximately 1,300,000 km2 of land from Texas to Saskatchewan. The integrity of these lands is under continual assault by long-established and newly-arrived invasive plant species, which can threaten native species and diminish land values and ecological goods and services by degrading desired grassland resources. The Great Plains are a mixture of privately and publicly owned lands, which leads to a patchwork of varying management goals and strategies for controlling invasive plants. Continually updated knowledge is required for efficient and effective management of threats posed by changing environments and invasive plants. Here we discuss …

Otoliths Of South-Western Australian Fish: A Photographic Catalogue, Chris Dowling, Kim Smith, Elaine Lek, Joshua Brown

Fisheries Research Reports

Due to the species-specific nature of otoliths and given they are often the only part of the fish preserved when fish die, otolith catalogues can be used in numerous applications, such as diet studies in fish eating animals, including pinnipeds, fish and sea birds; archaeological purposes such as reconstructing indigenous people’s diets from otoliths found in middens or evolutionary history of fish species by comparing fossilized otoliths. Given the unique mixture of subtropical and temperate fish, including many endemic species that occur off the southwest corner of WA having a catalogue for this area is extremely important for people working …

Integration Of Crop-Livestock Systems: An Opportunity To Protect Grasslands From Conversion To Cropland In The Us Great Plains, Alexander J. Smart, Daren Redfearn, Robert Mitchell, Tong Wang, Cody Zilverberg, Peter J. Bauman, Justin D. Derner, Julie Walker, Cody Wright

Native Plant Focused Publications

The Great Plains is a mixture of cropland and grassland mainly used for agricultural purposes, with grasslands under continual threat of conversion to cropland. Agriculturists are advocating for the integration of crop-livestock systems (ICLS) to recouple nutrient cycles, improve biodiversity, and increase resilience of agricultural operations. We address the benefits of ICLS in the Great Plains, contending that focus on improving soil health and financial stability of agricultural operations should reduce the conversion of grasslands to cropland. Using US Department of Agriculture National Agricultural Statistics Service Census of Agriculture survey data from the 1925−2017 category “cropland used only for pasture …

Scaup Depredation On Arkansas Baitfish And Sportfish Aquaculture, Stephen A. Clements, Brian S. Dorr, J. Brian Davis, Luke A. Roy, Carole R. Engle, Katie Hanson-Dorr, Anita M. Kelly

United States Department of Agriculture Wildlife Services: Staff Publications

Lesser scaup (Aythya affinis) and greater scaup (A. marila), hereafter scaup, consume a variety of aquatic invertebrates, plants, and occasionally small fish. Scaup have foraged on commercial aquaculture farms in the southern United States for decades. However, the types, abundance, and rate of fish exploitation by scaup on baitfish and sportfish farms are not well documented. Thus, information is needed to understand how fish and other foods influence scaup use of aquatic resources, and any potential economic effects of depredation of fish. From November–March in winters 2016–2017 and 2017–2018, we conducted 1,458 pond surveys to …

Silcock and Jorgensen (2020) list a total of seven accepted records with only two occurring in fall: an adult male at the Hyannis Cemetery, Grant Co., 01 Sep 2002 (Brogie 2003) and a female at Oliver Reservoir, Kimball Co., 07 Sep 2001 (Silcock 2001). The following documents the third Nebraska fall record for Black-throated Gray Warbler, the third record east of the Nebraska Panhandle, the first for northeast Nebraska, and the only NOURC accepted record (#2338) in the last decade.

A Brown-Capped Black-Capped Chickadee (Poecile Atricapillus) In Sarpy County, Nebraska, W. Ross Silcock, Phil Swanson

Nebraska Bird Review

Beginning 31 May 2021, Phil Swanson captured a series of videos and photos of an apparent family group of Black-capped Chickadees (BCCH). Five birds were seen together through 2 June, 2-4 through 6 June, and 2-3 through 9 June, during which all sightings included begging. Thereafter 1-2 birds per day were seen but without interactions between them. One of the family group had a brown cap (Figures 1, 2), and was presumably a juvenile based on its propensity for begging for food and partial replacement of its greater coverts (Pyle 1997). This condition has been described as “rare” (Sibley 2011), …
