Flight of the Freshwater Fish

The Hudson River provides for millions of people as a path for commercial and private transportation, a source of food and energy, and perhaps most importantly for many living in the tri-state area as a destination for recreation and relaxation. The most overlooked feature of the river is how the wildlife shows clear signs of a changing climate and rapid environmental response to the impacts of global warming on the river.

Entire populations of fish species in the lower Hudson have been forced to leave the river …

Sea Level Change In The Gulf Islands National Park Reserve, Southern British Columbia: Implications For The Interpretation Of Nearshore Archaeological Features, Glenda J. Wyatt

Salish Sea Ecosystem Conference

Sea level along the B.C. coastline has changed dramatically over the past 10,000 years due to isostatic rebound following deglaciation from the Fra ser Glaciation (Clague & James, 2002). In the future, sea levels globally are also predicted to rise according to the Intergovernmental Panel on Climate Change (IPCC) (2014), due to climate change. Lemmen et al. (2008), suggest that in the near future some B.C. coastal communities will have to deal with changes in shorelines due to rising sea levels, and hence erosional patterns, modifications to ecosystems and habitats, and potentially an altered marine food supply. This thesis examines …

Pacific Great Blue Heron Population Monitoring On Vancouver Island And The Surrounding Gulf Islands, Trudy A. Chatwin, Travis Heckford

Salish Sea Ecosystem Conference

The Pacific or Great Blue Heron fannini subspecies winters and breeds on Vancouver Island in locations within 5 km of the marine shoreline. Its visibility and close connection to the Salish Sea make it an important flagship species. Due to population concerns and threats associated with urban development, the Province of BC has coordinated monitoring of Great Blue Heron colonies on Vancouver Island and the adjacent Gulf Islands from 1997 through 2015. Starting in 2005, I trained volunteer stewards and technicians to use a standardized methodology to locate and assess heron colonies, count active nests, determine nest success and follow …

Exploration Of Student Biodiversity Knowledge And Decision-Making For A Wildlife Conservation Socioscientific Issue, Ashley R. Alred

School of Natural Resources: Dissertations, Theses, and Student Research

Global biodiversity, a foundation for ecosystem function, is diminishing at a rate unprecedented in the last 50 years. Biodiversity loss and ecosystem services deterioration is linked to increased food insecurity, reduced water quality and availability, decreased energy security, higher economic losses and human suffering (Millennium Ecosystem Assessment, 2005). Consequently, educators should invest in supporting students in their development of ecological understanding and formal decision-making skills so they are equipped with meaningful tools they can use as scientifically literate citizens. To contribute to that mission, this study seeks to explore student 1) comprehension and explanation of biodiversity concepts and 2) decision-making …

Finding The Best Remaining Black Hills Montane Grasslands, The First Step In Conservation, Hollis Marriott, Don Faber-Langendoen, David J. Ode

The Prairie Naturalist

Black Hills Montane Grassland is a rare and endangered plant community endemic to the Black Hills of western South Dakota and northeastern Wyoming. It is restricted to higher elevations on the Limestone Plateau in the western part of the uplift. Early visitors to the Black Hills wrote glowing reports of flower-filled grasslands on the Limestone Plateau. Lieutenant Colonel George A. Custer and his soldiers reveled in lush grass, and decorated the headgear of their horses with flowers (Custer 1875). Expedition botanist A. B. Donaldson “estimated the number of flowers in bloom in Floral Valley at 50, while an equal number …

Review Of Estimation Of Parameters For Animal Populations: A Primer For The Rest Of Us By Larkin A. Powell And George A. Gale, Max Post Van Der Burg

The Prairie Naturalist

“Me? A modeler? Never!” This is the opening challenge of the book, Estimation of Parameters for Animal Populations: A Primer for the Rest of Us, by Larkin Powell and George Gale. I say “challenge” because I think this book attempts to challenge the misconception that quantitative methods are out of reach for most biologists and wildlife scientists. When many of us attend college or graduate school to study wildlife science there’s a sense that, at some point, there will be math. But it appears that the attitude of many students toward this reality is to simply suffer through the …

Spatial Variation In Germination Of Two Annual Brome Species In The Northern Great Plains, Erin K. Espeland, Jane M. Mangold, Natalie M. West

The Prairie Naturalist

Downy brome or cheat grass (Bromus tectorum L.) and field brome (B. arvensis L.; Synonym = Bromus japonicus Thunb. ex Murr.; Japanese brome) are two annual exotic species that have increased the intensity and frequency of fire cycles in the Intermountain West of the United States, with millions of dollars in associated costs (DiTomaso 2000). These invasive brome species have a different impact in the Northern Great Plains of North America where they commonly co-occur in disturbed sites (White and Currie 1983, Haferkamp et al. 1993). In these mixed-grass prairie rangelands, annual bromes compete against other forage species …

Changes In The Prairie Naturalist For 2017: Some Bumps In The Road During Transition, Christopher N. Jacques

The Prairie Naturalist

By now it is obvious to most of our members and authors that The Prairie Naturalist (TPN) has experienced some delays in conducting journal-related business over the past few months. Publication of the June 2016 issue was slightly delayed and the December 2016 was mailed much later than planned. So I wanted to update our members on the current status, and other aspects, of TPN. As most of you know, when I transitioned into the Editorship of TPN, one of my first orders of business was to secure a new publication venue for the journal. Fortunately, the Department …

Review Of Waterfowl Of North America, Europe, And Asia: An Identification Guide By Sébastien Reeber, William L. Hohman

The Prairie Naturalist

Ducks, geese and swans (Family Anatidae) are the most popular and best studied group of birds in the world. The group has been the subject of classical books by Kortright (1942), Delacour (1954-1964), Bellrose (1976), Palmer (1976), Johnsgard (1978), and, most recently, Kear (2005) and Baldassarre (2014). The latest contribution to this rich legacy is an impressively illustrated identification guide for waterfowl found in North America, Europe and Asia by author and artist, Sébastien Reeber. This is an English-language version of Canards, Cygnes et Oies d’Europe, d’Asie et d’Amérique du Nord, published by Delachaux and Niestlé in late 2015. …

Review Of Plants Have So Much To Give Us, All We Have To Do Is Ask: Anishinaabe Botanical Teachings By Mary Siisip Geniusz (Edited By Wendy Makoons Geniusz, Illustrated By Annmarie Geniusz), Natasha Myhal, Kelly Kindscher

The Prairie Naturalist

Plants Have So Much to Give Us, All We Have to Do Is Ask offers a new look at Anishinaabe (Ojibwe) ethnobotany as told through traditional stories. Botanical teachings through stories are a way to pass down traditional knowledge from generation to generation. For example, Anishinaabe knowledge on plants was written and recorded in communities willing to share their knowledge with early scholars, such as Albert B. Reagan (1928), Huron H. Smith (1932), and Melvin R. Gilmore (1933). Each of these scholars spent time with an Anishinaabe community to learn about plants and primarily to provide written descriptions of plants …

Assessment Of Smallmouth Bass Growth And Mortality In Nebraska Waters, Benjamin J. Schall, Keith D. Koupal, Casey W. Schoenebeck, Keith L. Hurley

The Prairie Naturalist

Smallmouth bass (Micropterus dolomieu) have been introduced across Nebraska into a variety of waterbodies. However, an estimate of smallmouth bass growth and mortality in Nebraska waters has not been produced. The objectives of this study were to use historic sampling data to describe the growth of smallmouth bass in Nebraska lakes in relation to other regional models, growth among waterbody types (reservoirs, Interstate 80 [I-80] lakes, and rivers), estimates of age at quality, preferred, and memorable lengths, and mortality for Nebraska smallmouth bass populations. Mean length ± SE of Nebraska smallmouth bass at age 7 was 383 ± …

Review Of Booming From The Mists Of Nowhere: The Story Of The Greater Prairie-Chicken By Greg Hoch, Ross H. Hier

The Prairie Naturalist

The Greater Prairie-Chicken (Tympanuchus cupido pinnatus) is an iconic species inhabiting one of the most iconic and rarest habitats in the world—the tallgrass prairies of central North America. To tell the story of the Greater Prairie-Chicken is a monumental task. Its history is intricately woven into pre- and post-European settlement of the North American prairies in such a way that knowledge of the species is spread over several centuries. Thus, researching the “old and the new” regarding the Greater Prairie-Chicken requires a substantial literature review, much of which occurs in publications from the 1800s. Hoch has done a …

Reproductive Characteristics Of Landlocked Fall Chinook Salmon From Lake Oahe, South Dakota, Kelsen L. Young, Michael E. Barnes, Jeremy L. Kientz

The Prairie Naturalist

Lake Oahe, South Dakota, USA, landlocked fall Chinook salmon (Oncorhynchus tshawytscha) reproductive characteristics were examined over a 27 year period, from 1988 to 2015. Mean total lengths of spawning females ranged from 665 mm (1995) to 812 mm (2015) with considerable year-to-year variation. Post-spawn female weights varied, ranging from 2.02 kg (2000) to 5.55 kg (2015), with an overall mean of 3.04 kg. Fecundity peaked at 4,555 eggs per female in 2003, which was just 3 years after a low of 2,011 eggs per female in 2000. Relative fecundity based on female weight was greatest at 1,211 eggs/kg …

WA Marine Stewardship Council report series

The western rock lobster Panulirus cygnus (George) is taken by commercial and recreational fishers throughout its geographic range along the lower west coast of Western Australia. The main commercial fishery for P. cygnus is the West Coast Rock Lobster Managed Fishery (WCRLMF), which is Australia’s largest single-species fishery, currently worth about $400 million annually. Western rock lobster provides the basis for the economies of a number of coastal towns and also supports a recreational fishery.

Review Of Birds Of Montana By Jeffrey S. Marks, Paul Hendricks, And Daniel Casey, Scott G. Somershoe

The Prairie Naturalist

The Birds of Montana is an impressive-looking tome, that includes 659 pages, 155 color range maps, 73 illustrations of species, and 16 color photos of Montana’s habitats. Upon the first bend of the binding, the reader will quickly realize the impressive depth of detail and research that went into writing and completing this book. Although Montana is the fourth largest state, one of the least populated states, and has few “binoculars on the ground,” the state has a fascinating and extensive ornithological history. The Birds of Montana is not a field guide, but rather it is an astonishingly comprehensive reference …

Modern Fair-Weather And Storm Sediment Transport Around Ship Island, Mississippi: Implications For Coastal Habitats And Restoration Efforts, Eve Rettew Eisemann

Master's Theses

The Mississippi – Alabama barrier island chain is experiencing accelerated sea level rise, decreased sediment supply, and frequent hurricane impacts. These three factors drive unprecedented rates of morphology change and ecosystem reduction. All islands in the chain have experienced land loss on the order of hectares per year since records began in the 1840s. In 1969, Hurricane Camille impacted as a Category 5, breaching Ship Island, and significantly reduced viable seagrass habitat. Hurricane Katrina impacted as a Category 3 in 2005, further widening Camille Cut. To better understand the sustainability of these important islands and the ecosystems they support, sediment …

Migration Ecology Of American Woodcock (Scolopax Minor), Joseph Daniel Moore

Graduate Theses and Dissertations

Improving the understanding of American woodcock (Scolopax minor) migration ecology has been identified as a priority information need for woodcock management. Developments in remote tracking technology and analytical techniques present an opportunity to gain insight into woodcock migratory connectivity and migration phenology and to evaluate the degree in which the current two-region (Eastern and Central) basis for woodcock management represents migratory movements. To analyze woodcock migration using band return records, I excluded observations that took place during the migratory period. Using this dataset, 17.9% of records showed crossover between management regions, higher than the < 5% crossover found in studies including non-migratory band returns. During autumn migration, woodcock from the Central Region largely migrated to destinations within the Central Region, whereas woodcock from the Eastern Region migrated to destinations across their wintering range, mixing with individuals from the Central Region. Between 2013 and 2016, I deployed 75 satellite transmitters on woodcock. I tracked the migration paths of 61 woodcock and documented 88 woodcock migrations. Average migration duration was longer during spring migration (53 days) than during autumn migration (31 days) because woodcock made a higher number of close-together migratory stopovers, not because woodcock stayed at individual stopovers longer during spring migration. Woodcock captured in the Central Management Region used 2 primary migrations routes: a Western Route and a Central Route. The Western Route ran north-south, connecting the breeding and wintering grounds of the Central Management Region. The hourglass-shaped Central Route connected an area on the wintering grounds reaching from Texas to Florida, to sites throughout northeastern North America. Woodcock following the Central Route funneled between the Appalachian Mountains and the Mississippi Alluvial Valley in western Tennessee during both autumn and spring migration. A higher than anticipated percentage (36%, n = 12) of marked woodcock captured in Texas and Louisiana and monitored during spring migration migrated to breeding-period sites in the Eastern Management Region, raising questions about the biological basis of managing woodcock as separate populations. The supplementary material includes woodcock capture information (Appendix I), information on individual stopovers (Appendix II), and migration maps for individual woodcock (Appendix III).

Lower Prairie Creek Project Redwood National Park "Forest Owners", Susie Van Kirk

Susie Van Kirk Papers

"This file addresses forest ownerships, using deeds, patents, and maps in the Humboldt County Recorder’s Office, Eureka Courthouse. Pretty boring to wade through, these records, nonetheless, document how the public domain of northwestern California—the ancient redwood forests—came to be concentrated in the hands of timber companies. ... Land in the Lower Prairie Creek Project area (plus much, much other forest lands) was obtained through fraudulent patents and deed transactions involving David Evans and his associates for transfer to Scottish investors and eventually to “legitimate” timber companies. The end result, of course, is that what once belonged to indigenous people and …

Understanding Stakeholder Attitudes And Involvement In Habitat Conservation Plans And The Endangered Species Act, Kyle Andrew Rodgers

Masters Theses

The Endangered Species Act (ESA), established in 1973, was a landmark piece of environmental legislation and remains the standard for endangered species conservation. Implementation of the ESA has often been framed as pitting economic development against species conservation, inciting passions for and against endangered species conservation. The strength of opposing public opinions is highlighted by high-profile controversies such as those around the snail darter, northern spotted owl and the greater sage grouse. In an attempt to reduce conflict, the US Fish and Wildlife Service (USFWS) increasingly seeks to utilize collaborative, stakeholder-based processes that address stakeholder interests, attitudes, and values.

Ncer Assistance Agreement Annual Progress Report For Grant #83582401 - Assessment Of Stormwater Harvesting Via Manage Aquifer Recharge (Mar) To Develop New Water Supplies In The Arid West: The Salt Lake Valley Example, Ryan Dupont, Joan E. Mclean, Richard C. Peralta, Sarah E. Null, Douglas B. Jackson-Smith

Civil and Environmental Engineering Faculty Publications

The aims of the original proposed project remain the same, that is, to test the hypothesis that Managed Aquifer Recharge (MAR) for stormwater harvesting is a technically feasible, socially and environmentally acceptable, economically viable, and permittable option for developing new water supplies for arid Western urban ecosystems experiencing increasing population, and climate change pressures on existing water resources. The project is being carried out via three distinct but integrated components that include: 1) Monitoring of existing distributed Managed Aquifer Recharge (MAR) harvesting schemes involving a growing number of demonstration Green Infrastructure (GI) test sites; 2) Integrated stormwater/vadose zone/groundwater/ ecosystem services …

Predicting Post-Fire Change In West Virginia, Usa From Remotely-Sensed Data, Michael Strager P. Strager, Melissa Thomas-Van Gundy, Aaron E. Maxwell

Journal of Geospatial Applications in Natural Resources

Prescribed burning is used in West Virginia, USA to return the important disturbance process of fire to oak and oak-pine forests. Species composition and structure are often the main goals for re-establishing fire with less emphasis on fuel reduction or reducing catastrophic wildfire. In planning prescribed fires land managers could benefit from the ability to predict mortality to overstory trees. In this study, wildfires and prescribed fires in West Virginia were examined to determine if specific landscape and terrain characteristics were associated with patches of high/moderate post-fire change. Using the ensemble machine learning approach of Random Forest, we determined that …

Ecological Consequences Of Lost Anadromous Forage Fish In Freshwater Ecosystems, Steven R. Mattocks

Masters Theses

Beginning in the early 1600s, dam construction in New England obstructed anadromous fish access to spawning grounds during migration. As a result, anadromous forage fish populations have declined, which has impacted freshwater, marine, and terrestrial ecosystems. To determine the impacts of dams on anadromous forage fish and freshwater ecosystems, I used historical and current data to estimate population changes in alewives (Alosa pseudoharengus) from 1600-1900. A significant reduction in spawning habitat occurred in New England as a result of 1,642 dams constructed between 1600 and 1900, resulting in 14.8% and 16.6% lake and stream habitat remaining by 1900, …

Factors Affecting Habitat Quality For Wintering Wood Thrushes In A Coffee Growing Region In Honduras, Brett A. Bailey

Masters Theses

Amongst the diversity of taxa that occur in the Neotropics, 200 migratory bird species that breed in temperate North America can be found. Many of these populations have seen significant declines since the 1960s. The Wood Thrush, Hylocichla mustelina, is one such species. Shade coffee and other agroforestry practices show potential for benefiting migratory species, but the quality of coffee habitat and optimal habitat characteristics for Wood Thrushes remain unknown.

I surveyed a spatially complex, agricultural landscape in Honduras outside the recognized winter range of the Wood Thrush and radio-tagged 46 individuals within rustic coffee farms during the winters …

Professional Agricultural Workers Journal

Abstract

The study used calibrated Crop Environment Resource Synthesis (CERES) maize (corn) model to simulate maize (corn) physiological growth processes and yields under 2045 and 2075 projected climate change scenarios for six representative counties in Alabama. The future climatologies for two emission scenarios Representative Concentration Pathway (RCP) 4.5 (medium) and RCP 8.5 (high) were developed based on the IPSL-CM5A-MR high resolution climate model. Average yield decreases of 19.5% and 37.3% were, respectively, projected under RCP 4.5 and RCP 8.5 for 2045, and average yield decreases of 32.5% and 77.8% were, respectively, projected under RCP 4.5 and RCP 8.5 for 2075. …

Agenda: Flpma Turns 40, University Of Colorado Boulder. Getches-Wilkinson Center For Natural Resources, Energy, And The Environment

FLPMA Turns 40 (October 21)

The Bureau of Land Management (BLM) administers approximately 245 million acres of our public lands and yet, for most of our nation's history, these lands seemed largely destined to end up in private hands. Even when the Taylor Grazing Act of 1934 ushered in an important era of better managing public grazing districts and "promoting the highest use of the public lands," such use of our public lands still was plainly considered temporary, "pending its final disposal." It was not until 1976 with the passage of the Federal Land Policy and Management Act (FLPMA) that congress adopted a policy that …

Slides: Flpma In Its Historical Context, John D. Leshy

FLPMA Turns 40 (October 21)

Presenter: John D. Leshy, Sunderland Distinguished Professor of Law Emeritus, U.C. Hastings College of the Law

36 slides

This session traces the history of FLPMA including, among other things, its legislative, administrative, and historical antecedents, including for example, the Public Land Law Review Commission’s 1970 report, One Third of Our Nation’s Lands. It then considers FLPMA’s unique public lands policies and requirements and how they are reflected in the BLM’s management of public lands today.

Assessing Ecological And Economic Effects Of Derelict Fishing Gear: A Guiding Framework, Christopher F.G. Jeffrey, Kirk J. Havens, H. Ward Slacum Jr., Donna Marie Bilkovic, Danielle Zaveta, Andrew M. Scheld, Sean Willard, John D. Evans

Reports

Developing standardized protocols to assess the ecological and socio-economic effects of marine debris – especially, derelict fishing gear – is critical for the protection of natural resources and for evaluating policies and programs designed to reduce and remove debris. This document outlines a Derelict Fishing Gear Assessment Framework to guide the development and implementation of derelict gear assessment, management and mitigation. The framework draws from techniques and protocols developed to assess derelict crab traps effects in the Chesapeake Bay and on past derelict gear assessments either conducted by or known to the framework authors. However, this framework is generalized and …

Ecological And Economic Effects Of Derelict Fishing Gear In The Chesapeake Bay 2015/2016 Final Assessment Report, Donna M. Bilkovic, H. Ward Slacum Jr., Kirk J. Havens, Danielle Zaveta, Christopher F.G. Jeffrey, Andrew M. Scheld, David Stanhope, Kory Angstadt, John D. Evans

Reports

Derelict fishing gear represents a major challenge to marine resource management: whether through deliberate abandonment or through accidental loss, derelict traps in particular have significant negative effects both economic (e.g., reduced fishery harvest from ghost fishing and gear competition that leads to the reduced efficiency of active gear) and ecological (e.g., degraded habitats and marine food webs and crab and bycatch mortality). Throughout the Chesapeake Bay, commercial harvest of hard-shelled blue crabs is a major fishing activity: every year sees the deployment of several hundred thousand blue crab traps (known locally as crab “pots”) across the Bay, of which an …

Takeover On The Tallgrass Prairie: How Lespedeza Cuneata Establishes Dominance, Morgan Rae Walder

Theses and Dissertations

Invasion ecology aims to study mechanisms by which invasive species are able to enter, establish, and spread within an ecosystem. This study analyzed Darwin’s naturalization and the biotic resistance hypotheses as the most likely explanations for invasion by an exotic legume, Lespedeza cuneata, into a tallgrass prairie. Darwin’s naturalization hypothesis posits that exotic species are less able to establish in communities that have related species, because similarity in morphology and function promotes intense competition for resources. The biotic resistance hypothesis states that competitors, herbivores, and pathogens already present in the community limit the colonization, naturalization, and persistence of invaders, therefore …
