Bison Movements Change With Weather: Implications For Their Continued Conservation In The Anthropocene, Nicholas A. Mcmillan, Samuel D. Fuhlendorf, Barney Luttbeg, Laura E. Goodman, Craig A. Davis, Brady W. Allred, Robert G. Hamilton

Department of Agronomy and Horticulture: Faculty Publications

Animal movement patterns are affected by complex interactions between biotic and abiotic landscape conditions, and these patterns are being altered by weather variability associated with a changing climate. Some animals, like the American plains bison (Bison bison L.; hereafter, plains bison), are considered keystone species, thus their response to weather variability may alter ecosystem structure and biodiversity patterns. Many movement studies of plains bison and other ungulates have focused on point-pattern analyses (e.g., resource-selection) that have provided information about where these animals move, but information about when or why these animals move is limited. For example, information surrounding the …

Contemporary Challenges And Opportunities For The Management Of Bird Damage At Field Crop Establishment, Christophe Sausse, Alice Baux, Michel Bertrand, Elsa Bonnaud, Sonia Canavelli, Alexandra Destrez, Page E. Klug, Lourdes Olivera, Ethel Rodriguez, Guilllermo Tellechea, Sebastian Zuil

United States Department of Agriculture Wildlife Services: Staff Publications

Bird damage, from sowing to crop establishment, is an important issue for farmers in many parts of the world. However, reliable and cost-effective solutions remain elusive because management tools and research on the subject are limited. The spatial variability of damage across landscapes and the adaptative behaviour of birds create further challenges. Additionally, the issue must be tackled at the landscape scale and involve a variety of stakeholders with conflicting interests and objectives. We summarize some of the challenges and opportunities identified to face these difficulties and address four major research directions for operational solutions including 1) crop damage assessment, …

Honey Bee Foraged Pollen Reveals Temporal Changes In Pollen Protein Content And Changes In Forager Choice For Abundant Versus High Protein Flowers, Gabriela Quinlan, Meghan Milbrath, Clint Otto, Autumn Smart, Deborah D. Iwanowicz, Robert Cornman, Rufus Isaacs

Department of Entomology: Faculty Publications

Protein derived from pollen is an essential component of healthy bee diets. Protein content in honey bee foraged pollen varies temporally and spatially, but the drivers underlying this variation remain poorly characterized. We assessed the temporal and spatial variation in honey bee collected pollen in 12 Michigan apiaries over 3 summers (2015–2017). We simultaneously monitored forage in flowering habitats (uncultivated floristically-rich areas and conservation program land) near these apiaries throughout the growing season. We used these data, along with data from the literature on plant pollen protein content, to determine if honey bees collected a greater proportion of pollen from …

Landscape Use By Fishers (Pekania Pennanti): Core Areas Differ In Habitat Than The Entire Home Range, Jennifer R. Kordosky, Eric M. Gese, Craig M. Thompson, Patricia A. Terletzky, Kathryn L. Purcell, Jon D. Schneiderman

United States Department of Agriculture Wildlife Services: Staff Publications

Home ranges have long been studied in animal ecology. Core areas may be used at a greater proportion than the rest of the home range, implying the core contains dependable resources. The Pacific fisher (Pekania pennanti (Erxleben, 1777)) is a rare mesocarnivore occupying a small area in the Sierra Nevada Mountains, California, USA. Once statewide, fishers declined in the 1900s due to trapping, habitat fragmentation, and development. Recently, drought induced by climate change may be affecting this population. We examined space use of fishers in their core versus their home range for levels of anthropogenic modifications (housing density, road density, …

The Traits That Predict The Magnitude And Spatial Scale Of Forest Bird Responses To Urbanization Intensity, Grant D. Paton, Alexandra V. Shoffner, Andrew M. Wilson, Sara A. Gagné

Environmental Studies Faculty Publications

As humans continue moving to urban areas, there is a growing need to understand the effects of urban intensification on native wildlife populations. Forest species in remnant habitat are particularly vulnerable to urban intensification, but the mechanisms behind these effects are poorly understood. An understanding of how species traits, as proxies for mechanisms, mediate the effects of urban intensification on forest species can help fill this knowledge gap. Using a large point count dataset from the Second Pennsylvania Breeding Bird Atlas, we tested for the effects of species traits on the magnitude and spatial scale of the responses of 58 …

Landscape Factors Affecting Foraging Flight Altitudes Of Great Blue Heron In Maine; Relevance To Wind Energy Development, Lauren Dolinski

Honors College

In an attempt to increase alternative energy sources, there has been greater development of wind farms across the United States. This expanded development may pose a potential threat to birds that are flying overhead (EIA 2017, Leung and Yang 2011). More information is needed on the factors that affect a bird’s behavior while flying and if the current policies and dimensions of wind turbines interfere with flight altitudes. We used data from GPS-marked great blue herons (Ardea herodias) in Maine to classify their flight altitudes relative to wind turbine height and assess different landscape factors that affect flight …

Hemlock Woolly Adelgid (Hemiptera: Adelgidae) Management In Forest, Landscape, And Nursery Production, Elizabeth P. Mccarty, Karla M. Addesso

Agricultural and Environmental Sciences Faculty Research

Hemlock woolly adelgid, Adelges tsugae (Annand) (Hemiptera: Adelgidae), has caused significant damage to both eastern [Tsuga canadensis (L.) Carrière] and Carolina hemlock (Tsuga caroliniana Englemann) (Pinales: Pinaceae) since it was first reported in the eastern United States. This adelgid is particularly damaging to these hemlock species due to a lack of co-evolved plant defenses and natural enemies able to suppress hemlock woolly adelgid populations. Management of hemlock woolly adelgid relies heavily on insecticides to prevent death of vulnerable trees. Biological control programs have released natural enemies of hemlock woolly adelgid to aid in control at the landscape level. …

Societal Rebirth: The Importance Of Spirituality, Lauren Rothstein

English Department: Traveling American Modernism (ENG 366, Fall 2018)

This article offers an exploration of what the social consequences are when modernity strips away religious-human relationships to the land. The two texts Black Elk Speaks and Grapes of Wrath both include moments of anonymous forces imposing systematic modernization on society. Particularly, I try to understand the controversial subject of societal rebirths, traditionally defined through employment and steady food source availability. This paper proposes an approach to societal rebirths that emphasizes the importance of spiritual connection to the land through a critical analysis of Bakhtin's theory of Chronotope and Leopold's theory of Land Ethic. On the issue of spiritual connection …

Using Systematic Conservation Planning To Establish Management Priorities For Freshwater Salmon Conservation, Matanuska-Susitna Basin, Ak, Usa, Andrew W. Witt, Edd Hammill

Ecology Center Publications

1- The Alaskan Matanuska-Susitna Basin (MSB) provides habitat for all five Pacific salmon species, and their large seasonal spawning runs are important both ecologically and economically. However, the encroachment of human development through urbanization and extractive industries poses a serious risk to salmon habitat in the MSB.

2- Using systematic conservation planning techniques, different methods of incorporating anthropogenic risks were assessed to determine how to cost-effectively conserve salmon habitat in the area.

3- The consequences of four distinct conservation scenarios were quantified: no consideration of either urbanization or extractive industries (‘Risk ignored’ scenario); accounting for the risk of urbanization, and …

Turner, Thomas T. Veblen, Rupert Seidl

Geography

Increasing evidence indicates that forest disturbances are changing in response to global change, yet local variability in disturbance remains high. We quantified this considerable variability and analyzed whether recent disturbance episodes around the globe were consistently driven by climate, and if human influence modulates patterns of forest disturbance. We combined remote sensing data on recent (2001–2014) disturbances with in-depth local information for 50 protected landscapes and their surroundings across the temperate biome. Disturbance patterns are highly variable, and shaped by variation in disturbance agents and traits of prevailing tree species. However, high disturbance activity is consistently linked to warmer and …

Habitat Selection By The Northern Long-Eared Myotis (Myotis Septentrionalis) In The Midwestern United States: Life In A Shredded Farmscape, Jeremy A. White, Patricia Freeman, Cliff A. Lemen

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Populations of the Northern Long-Eared Myotis (Myotis septentrionalis) have declined dramatically in recent years in eastern North America due to white-nose syndrome. Although M. septentrionalis was once common in parts of eastern North America, few studies have examined habitat selection of this species in an agricultural landscape. We used acoustical methods to quantify bat activity and construct a habitat model of M. septentrionalis in an intensively farmed area in the Midwestern United States, where mortality from white-nose syndrome has not yet been observed. Our study confirms that M. septentrionalis prefers forest and avoids open habitats in this agricultural …

Shorebird Stopover Habitat Decisions In A Changing Landscape, Caitlyn Gillespie, Joseph J. Fontaine

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

To examine how habitat use by sandpipers (Calidris spp.; Baird’s sandpipers, dunlin, least sandpipers, pectoral sandpipers, semipalmated sandpipers, stilt sandpipers, and white-rumped sandpipers) varies across a broad suite of environmental conditions, we conducted surveys at wetlands throughout the spring migratory period in 2013 and 2014 in 2 important stopover regions: the Rainwater Basin (RWB) in Nebraska, USA, and the Prairie Pothole Region (PPR) in South Dakota, USA. Because providing adequate energetic resources for migratory birds is a high priority for wetland management, we also measured invertebrate abundance at managed wetlands in the RWB to determine how food abundance influences …

A Framework For Assessing Alternative Agro-Ecosystems: Finding Multi-Functional Solutions For Sustainable Urban Landscapes., Thais H. Thiesen Ms.

FIU Electronic Theses and Dissertations

Creating sustainable urban landscapes in light of growing population pressures requires interdisciplinary multi-functional solutions. Alternative agro-ecosystems described as food forests, permaculture gardens, and/or edible landscapes among others could offer potential ways to address the social, economic and ecological goals of various stakeholders simultaneously. The present research used a unique rubric, the Permaculture and Agro-ecosystems Sustainability Scorecard (PASS) that combines existing agricultural and landscape sustainability indicators in order to assess alternative agro-ecosystems. The rubric evaluates provisioning, regulating, supporting and cultural ecosystem services such as pollinator presence, biodiversity, pesticides and fertilizer use, carbon sequestration and human interactions. The PASS was used to …

Seascapes As A New Vernacular For Pelagic Ocean Monitoring, Management And Conservation, Maria T. Kavanaugh, Matthew J. Oliver, Francisco P. Chavez, Ricardo M. Letelier, Frank E. Muller-Karger, Scott C. Doney

Marine Science Faculty Publications

For terrestrial and marine benthic ecologists, landscape ecology provides a framework to address issues of complexity, patchiness, and scale—providing theory and context for ecosystem based management in a changing climate. Marine pelagic ecosystems are likewise changing in response to warming, changing chemistry, and resource exploitation. However, unlike spatial landscapes that migrate slowly with time, pelagic seascapes are embedded in a turbulent, advective ocean. Adaptations from landscape ecology to marine pelagic ecosystem management must consider the nature and scale of biophysical interactions associated with organisms ranging from microbes to whales, a hierarchical organization shaped by physical processes, and our limited capacity …

Tree-Mycorrhizal Associations Detected Remotely From Canopy Spectral Properties, Joshua B. Fisher, Sean Sweeney, Edward R. Brzostek, Tom P. Evans, Daniel J. Johnson, Jonathan A. Myers, Norman A. Bourg, Amy T. Wolf, Robert W. Howe, Richard P. Philllips

Biology Faculty Publications & Presentations

A central challenge in global ecology is the identification of key functional processes in ecosystems that scale, but do not require, data for individual species across landscapes. Given that nearly all tree species form symbiotic relationships with one of two types of mycorrhizal fungi – arbuscular mycorrhizal (AM) and ectomycorrhizal (ECM) fungi – and that AM- and ECM-dominated forests often have distinct nutrient economies, the detection and mapping of mycorrhizae over large areas could provide valuable insights about fundamental ecosystem processes such as nutrient cycling, species interactions, and overall forest productivity. We explored remotely sensed tree canopy spectral properties to …

Local Avian Density Influences Risk Of Mortality From Window Strikes, Ann M. Sabo, Natasha D.G. Hagemeyer, Ally S. Lahey, Eric L. Walters

Biological Sciences Faculty Publications

Up to a billion birds die per year in North America as a result of striking windows. Both transparent and reflective glass panes are a cause for concern, misleading birds by either acting as invisible, impenetrable barriers to desired resources, or reflecting those resources over a large surface area. A high number of window strikes occur during migration, but little is known about the factors of susceptibility, or whether particular avian taxa are more vulnerable than others. We report on a study of window strikes and mist-netting data at the Virginia Zoological Park (Norfolk, Virginia, USA), conducted in the autumn …

Survey For Spotted-Wing Drosophila (Diptera: Drosophilidae) In The Five-County Nursery Production Region Of Middle Tennessee, Usa, Karla M. Addesso, Jason B. Oliver, Paul A. O'Neal

Agricultural and Environmental Sciences Faculty Research

Through global trade, spotted-wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), a native of Southeast Asia, has spread to at least 3 other continents since 2008. Initial reports of the fly in new regions often are associated with damage in agriculture fields, but the fly may be present in the landscape for years before populations reach a level at which they become a pest in fruit production. In 2012, spotted wing drosophila was reported in blueberry fields in eastern Tennessee, USA, for the first time. In order to determine whether the fly was established in middle Tennessee, we conducted landscape surveys …
