Reducing Protected Lands In A Hotspot Of Bee Biodiversity: Bees Of Grand Staircase-Escalante National Monument, Joseph S. Wilson, Matt Kelly, Olivia Messinger Carril Dec 2018

Reducing Protected Lands In A Hotspot Of Bee Biodiversity: Bees Of Grand Staircase-Escalante National Monument, Joseph S. Wilson, Matt Kelly, Olivia Messinger Carril

Biology Faculty Publications

Grand Staircase-Escalante National Monument is a federally protected area found in central southern Utah. Designated in 1996 by President William J. Clinton, it was recently reduced in size by President Donald J. Trump in a proclamation that turned the one large monument into three smaller ones. A long-term, standardized study of the bees had been conducted from 2000–2003, revealing 660 species. The bee communities of the area are characterized by being spatially heterogeneous; most of the bees occur in isolated areas, with only a few being both abundant and widespread. Here we examine what affect the recent resizing of the …


Relationships Among Biodiversity Dimensions Of Birds In Nebraska, Nadejda Mirochnitchenko Dec 2018

Relationships Among Biodiversity Dimensions Of Birds In Nebraska, Nadejda Mirochnitchenko

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

Biological diversity, or biodiversity, is a multi-dimensional concept that can be decomposed to measure information about taxonomic, phylogenetic, and functional variation within communities. Although the dimensions of biodiversity are interrelated, the assumption that measuring one dimension of diversity can inform about patterns in another dimension does not necessarily follow from theory or empirical study. The relationships among biodiversity dimensions is not well understood, nor how differences among dimensions could influence conservation decision making. Using the avian community as a study system, we explored the relationships of breadth metrics from the taxonomic, phylogenetic, and functional dimensions among each other and across …


Notes: Two-Headed White-Tailed Deer Fetus, William F. Jensen, Daniel M. Grove, Ryan J. Herigstad, William J. Haase Dec 2018

Notes: Two-Headed White-Tailed Deer Fetus, William F. Jensen, Daniel M. Grove, Ryan J. Herigstad, William J. Haase

The Prairie Naturalist

On 6 April 2018 a female white-tailed deer (Odocoileus virginianus dakotensis) was hit and killed by a vehicle along HWY 1806 in rural Morton County, North Dakota, USA (N46o 38.617; W100o 42.901). Based upon dental eruption and wear (Severinghaus 1949), the female was estimated to be a >4.5 years-of-age. A male fetus with parapagus diprosopus (i.e., shared face) apparently was expelled from the adult female, and a domestic canine (Canis lupus familiaris) carried the fetus to a private residence. The resident contacted the North Dakota Game and Fish Department (NDGFD) to turn in the fetus. On 10 April 2018, NDGFD …


Review: Canids Of The World: Wolves, Wild Dogs, Foxes, Jackals, Coyotes, And Their Relatives. José R. Castelló., Jonathan (Jon) Way Dec 2018

Review: Canids Of The World: Wolves, Wild Dogs, Foxes, Jackals, Coyotes, And Their Relatives. José R. Castelló., Jonathan (Jon) Way

The Prairie Naturalist

Canids of the World is one of those reads where just when you think that something cannot be beat, this book comes out. What I mean by that is that I have read many works on wolves and other canids, most recently Nate Blakeslee’s American Wolf (Way 2017), and I have enjoyed and been enthralled with many of them. But Canids of the World may take the cake for being the most impressive book available on canids. For a modest price of just under $30.00, you can own a book that has over 600 amazing high-resolution glossy photographs of every …

Edges And Rushes Of Minnesota: The Completeguidetospeciesidentification. Welby R. Smith; Photography By Richard Haug., Edward S. Dekeyser

The Prairie Naturalist

Even the most seasoned individual with a plant identification background can relate to the difficulty of identifying sedges and rushes to the species level. Historically, one has had to rely on dichotomous keys to identify a sedge or rush species in the field. After hours of frustration, a person ends up collecting the plant and, if lucky, bringing the collection back to a herbarium where it can be compared to known specimens. I have been collecting and identifying sedge and rush species for over 25 years, and author Welby Smith along with photographer Richard Haug have published what I believe …


Review: Behavior Of The Golden Eagle: An Illustrated Ethogram. David H. Ellis (Illustrated By N. John Schmitt)., Jeremy E. Guinn Dec 2018

Review: Behavior Of The Golden Eagle: An Illustrated Ethogram. David H. Ellis (Illustrated By N. John Schmitt)., Jeremy E. Guinn

The Prairie Naturalist

Author David H. Ellis and illustrator N. John Schmitt deliver precisely what is promised in Behavior of the Golden Eagle: An Illustrated Ethogram. This “little volume,” as the author coins it, represents a single source for defining, identifying, and describing behaviors of the Golden Eagle (Aquila chrysaetos). With the inclusion of Schmitt’s exceptional drawings, the book is a piece of art, as well as the most useful manual describing Golden Eagle behaviors. Nearly four decades earlier, Ellis (1979) authored the very first Golden Eagle ethogram—the set of repeated standard behaviors for a species called action patterns—and in his new book, …

Metabolic Gas Emissions From Prairie Soil Containing Foraging Termites, Charles E. Konemann, B.M. Kard, Tom A. Royer, Mark E. Payton

The Prairie Naturalist

Differences in subterranean termite metabolic gas emissions are readily observed in laboratory experiments. However, in natural field ecosystems a primary difficulty in measuring subterranean termite gases is non-homogeneous distribution of foraging termites in soil. Our field experiment was designed to aggregate foragers of the 'eastern subterranean termite', Reticulitermes flavipes Kollar (EST), in one of four flux chamber configurations placed on a tallgrass prairie throughout 2014 and 2015. We used differently configured flux chambers to measure metabolic gas emissions from soil with or without foraging termites on The Joseph H. Williams Tallgrass Prairie Preserve (TGPP) in north-central Oklahoma. Foraging termitesaggregated in …


Review: North American Ducks, Geese & Swans: Identification Guide. Frank S. Todd., Kevin M. Ringelman Dec 2018

Review: North American Ducks, Geese & Swans: Identification Guide. Frank S. Todd., Kevin M. Ringelman

The Prairie Naturalist

The North American Duck, Geese & Swans: Identification Guide, released in 2018, is the culmination of a lifetime of waterfowl photography by the late Frank Todd. Indeed, this book stands apart from other identification guides as being entirely photo-driven, with minimal introductory material, notations of field marks, or descriptions of the various waterfowl species. It is small enough to be carried in the field (6.5” × 9” × 0.5”), but most readers will find it less useful than a standard bird identification book (Sibley 2014), even for waterfowl. As the title suggests, the Todd guide focuses on North American species, …

Implications Of Spatially Variable Costs And Habitat Conversion Risk In Landscape-Scale Conservation Planning, Max Post Van Der Burg, Neil Chartier, Ryan Drum Dec 2018

Implications Of Spatially Variable Costs And Habitat Conversion Risk In Landscape-Scale Conservation Planning, Max Post Van Der Burg, Neil Chartier, Ryan Drum

USGS Northern Prairie Wildlife Research Center

‘‘Strategic habitat conservation’’ refers to a process used by the U.S. Fish and Wildlife Service to develop cost-efficient strategies for conserving wildlife populations and their habitats. Strategic habitat conservation focuses on resolving uncertainties surrounding habitat conservation to meet specific wildlife population objectives (i.e., targets) and developing tools to guide where conservation actions should be focused on the landscape. Although there are examples of using optimization models to highlight where conservation should be delivered, such methods often do not explicitly account for spatial variation in the costs of conservation actions. Furthermore, many planning approaches assume that habitat protection is a preferred …

Trash Talk: The Effects Of Plastic Pollution On Seabirds In Narragansett Bay, Erin A. O'Neill

Pell Scholars and Senior Theses

Plastic pollution in the ocean is a global concern with more than 8 million tons of plastic dumped into our oceans every year. This policy paper assesses plastic pollution in Narragansett Bay and the negative implications it holds on local seabird populations. Also, essential background information on plastic production and throwaway culture is provided. Moreover, the biological significance of seabirds is described, highlighting the vital role such populations play in local ecosystems such as Narragansett Bay. This paper contributes research to the global issue of plastic pollution by observing declining native wildlife life populations, such as seabirds, on a local …


Prairie Reconstruction Unpredictability And Complexity: What Is The Rate Of Reconstruction Failures?, Jack E. Norland, Cami Dixon, Diane Larson, Kristine Askerooth, Benjamin A. Geaumont Dec 2018

Prairie Reconstruction Unpredictability And Complexity: What Is The Rate Of Reconstruction Failures?, Jack E. Norland, Cami Dixon, Diane Larson, Kristine Askerooth, Benjamin A. Geaumont

USGS Northern Prairie Wildlife Research Center

The outcomes of prairie reconstructions are subject to both unpredictability and complexity. Prairie, tallgrass, and mixed grass reconstruction is defined as the planting of a native herbaceous seed mixture composed of multiple prairie species (10 or more) in an area where the land has been heavily cultivated or anthropogenically disturbed. Because of the unpredictability and complexity inherent in reconstructions, some outcomes end up being failures dominated by exotic species. We propose that these failures follow a fat-tailed distribution as found in other complex systems. Fat-tailed distributions follow the Pareto principle, where 80% of the time reconstructions work as expected but …


New Breeding Record And Location For Wilson’S Phalarope (Phalaropus Tricolor) In The Nebraska Great Plains, Usa, Madison O. Sutton, Nico Arcilla Dec 2018

New Breeding Record And Location For Wilson’S Phalarope (Phalaropus Tricolor) In The Nebraska Great Plains, Usa, Madison O. Sutton, Nico Arcilla

The Prairie Naturalist

Wilson’s phalarope (Phalaropus tricolor; Scolopacidae) is a migratory shorebird that relies on interior wetlands for foraging and breeding (Colwell and Jehl 1994, van Gils et al. 2018). Its global population status is unclear (Colwell and Jehl 1994, Lesterhuis and Clay 2010), and is variously listed as declining (Morrison et al. 2006, van Gils et al. 2018), increasing (Andres 2009, BirdLife International 2018), and exhibiting a long-term decline but recent stability (Sauer et al. 2011, Andres et al. 2012). Its global population estimate of 1.5 million birds has not been updated for 30 years, since 1988 (Colwell and Jehl 1994, Lesterhuis …


Comparison Of Northern Flying And Red Squirrel Phylogenies With Focus On The Insular United States, Alyssa M. Kiesow, Hugh B. Britten Dec 2018

Comparison Of Northern Flying And Red Squirrel Phylogenies With Focus On The Insular United States, Alyssa M. Kiesow, Hugh B. Britten

The Prairie Naturalist

Northern flying squirrel (Glaucomys sabrinus) and red squirrel (Tamiasciurus hudsonicus) populations are endemic to northern North America, including the Black Hills. The Black Hills populations are considered disjunct from other populations within their range. We examined insular populations to determine whether arboreal squirrels in the Black Hills each represent a unique population. We trapped and collected ear samples from northern flying and red squirrels in the Black Hills and in areas of Montana, Wyoming, Idaho, Utah, Minnesota, and Wisconsin to infer population phylogenies with special consideration of the Black Hills population. Microsatellite loci and two mtDNA sequences were used for …

Greetings GPNSS members! By the time you read this editorial, many of have been experiencing the fury unleashed by ‘Old Man Winter’ and may find yourself counting the days until warmer spring temperatures return once again to the Great Plains. Until then, just a couple more months of bitter cold temperatures, strong winds, and blowing and drifting snow. But not to worry, winter also provides the cold weather enthusiasts among us a chance to enjoy a range of outdoor recreational opportunities, a chance to reflect on the previous year in review, exciting professional and personal opportunities ushered in by the …


Red-Bellied Snake (Storeria Occipitomaculata) Copulation In South Dakota, Drew R. Davis Dec 2018

Red-Bellied Snake (Storeria Occipitomaculata) Copulation In South Dakota, Drew R. Davis

The Prairie Naturalist

Storeria occipitomaculata is a small, terrestrial species of snake that occurs across much of eastern North America (Ernst and Barbour 1989, Ernst 2002, Ernst and Ernst 2003). Due to this widespread distribution, S. occipitomaculata faces varied climates that likely result in regional differences in reproductive phenology. Much of what is known about the reproductive ecology of S. occipitomaculata has been documented from the southeastern portion of its range in North America (South Carolina: Semlitsch and Moran 1984, North Carolina: Willson and Dorcas 2004), though Blanchard (1937) studied a population from northern Michigan. The exact reproductive timing in this species has …

Cryptic Diversity In The Mexican Highlands: Thousands Of Uce Loci Help Illuminate Phylogenetic Relationships, Species Limits And Divergence Times Of Montane Rattlesnakes (Viperidae: Crotalus ), Christopher Blair, Robert W. Bryson Jr, Charles W. Linkem, David Lazcano, John Klicka, John E. Mccormack

Publications and Research

With the continued adoption of genome‐scale data in evolutionary biology comes the challenge of adequately harnessing the information to make accurate phylogenetic inferences. Coalescent‐based methods of species tree inference have become common, and concatenation has been shown in simulation to perform well, particularly when levels of incomplete lineage sorting are low. However, simulation conditions are often overly simplistic, leaving empiricists with uncertainty regarding analytical tools. We use a large ultraconserved element data set (>3,000 loci) from rattlesnakes of the Crotalus triseriatus group to delimit lineages and estimate species trees using concatenation and several coalescent‐based methods. Unpartitioned and partitioned maximum …


A Glimpse Into The Ecological Communities Of Camp Greenwood, Rachael Noteboom Nov 2018

A Glimpse Into The Ecological Communities Of Camp Greenwood, Rachael Noteboom

Honors Projects

There is a Presbyterian summer camp near Greenville, Michigan that is home to beautiful wetlands with a variety of wildlife. This camp is nestled between multiple larger connected lakes and surrounded by many large waterfront properties. The number of campers has dwindled in recent years and the council in charge of the land is desperate to sell the most ecologically important sections of the camp, if not all of the land, to developers for multi-million dollar price tags. My dad is on the committee trying to convince the council and the community to save the camp from development.

13 Terrestrial Wetlands, Randall Kolka, Carl T Trettin Nov 2018

13 Terrestrial Wetlands, Randall Kolka, Carl T Trettin

USGS Northern Prairie Wildlife Research Center

The objective of this chapter is to characterize the distribution of carbon stocks and fluxes in terrestrial wetlands within North America. The approach was to synthesize available literature from field measurements with analyses of resource inventory data to estimate wetland area, carbon stocks, and net ecosystem exchange (NEE) of carbon and methane (CH4) fluxes of terrestrial wetlands (see Appendices 13A, p. 547, and 13B, p. 557, for details1). Then, the findings employed from large-scale simulation studies provided additional context, with consideration given to the effects of disturbance regimes, restoration and creation of terrestrial wetlands, and the application of modeling tools …


The European Union And The Establishment Of Marine Protected Areas In Antarctica, Nengye Liu Nov 2018

The European Union And The Establishment Of Marine Protected Areas In Antarctica, Nengye Liu

Research Collection Yong Pung How School Of Law

This paper examines how the EU can best use its powers to establish marine protected areas (MPAs) in Antarctica. It first discusses the EU’s role in Antarctic governance and legal basis for the EU’s actions, with particular focus on the pending Joined Cases C-625/15 and C-659/16 at the Court of Justice of the European Union. Secondly, the paper analyses the negotiation process of the EU’s MPA proposals in the Southern Ocean within the Commission for the Conservation of Antarctic Marine Living Resources. Thirdly, it provides suggestions regarding the EU’s potential actions that might help achieve proposed Antarctic MPAs.

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

The biodiversity of urban and post-industrial ecosystems is a highly relevant and growing new frontier in ecological research. Even so, the functionality of these ecosystems may not always be successfully predicted based on prior biodiversity and ecosystem functioning theory. Indeed, evidence suggests that the general biological impoverishment within the urban context envisioned thirty years ago was overstated. Many of the world’s urban centers support some degree of biodiversity that is indigenous, as well as a complex array of non-native species, resulting in highly functional, and often, novel communities. For over two decades, a multi-disciplinary team has examined the sub-lethal impact …

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Natural history collections spanning multiple decades provide fundamental historical baselines to measure and understand changing biodiversity. New technologies such as next generation DNA sequencing have considerably increased the potential of museum specimens to address significant questions regarding the impact of environmental changes on host and parasite/pathogen dynamics. We developed a new technique to identify intestinal helminth parasites and applied it to shrews (Eulipotyphla: Soricidae) because they are ubiquitous, occupy diverse habitats, and host a diverse and abundant parasite fauna. Notably, we included museum specimens preserved in various ways to explore the efficacy of using metabarcoding analyses that may enable identification …

Multi-Element Fingerprinting Of Waters To Evaluate Connectivity Among Depressional Wetlands, Yuxiang Yuan, Xiaoyan Zhu, David M. Mushet, Marinus L. Otte Oct 2018

Multi-Element Fingerprinting Of Waters To Evaluate Connectivity Among Depressional Wetlands, Yuxiang Yuan, Xiaoyan Zhu, David M. Mushet, Marinus L. Otte

USGS Northern Prairie Wildlife Research Center

Establishing the connectivity among depressional wetlands is important for their proper management, conservation and restoration. In this study, the concentrations of 38 elements in surface water and porewater of depressional wetlands were investigated to determine chemical and hydrological connectivity of three hydrological types: recharge, flow-through, and discharge, in the Prairie Pothole Region of North America. Most element concentrations of porewater varied significantly by wetland hydrologic type (p < 0.05), and increased along a recharge to discharge hydrologic gradient. Significant spatial variation of element concentrations in surface water was observed in discharge wetlands. Generally, higher element concentrations occurred in natural wetlands compared to wetlands with known disturbances (previous drainage and grazing). Electrical conductivity explained 42.3% and 30.5% of the variation of all element concentrations in porewater and surface water. Non-metric multidimensional scaling analysis showed that the similarity decreased from recharge to flowthrough to discharge wetland in each sampling site. Cluster analysis confirmed that element compositions in porewater of interconnected wetlands were more similar to each other than to those of wetlands located farther away. Porewater and surface water in a restored wetland showed similar multi-element characteristics to natural wetlands. In contrast, depressional wetlands connected by seeps along a deactivated drain-tile path and a grazed wetland showed distinctly different multi-element characteristics compared to other wetlands sampled. Our findings confirm that the multi-element fingerprinting method can be useful for assessing hydro-chemical connectivity across the landscape, and indicate that element concentrations are not only affected by land use, but also by hydrological characteristics.

Ten Years Tracking The Migrations Of Small Landbirds: Lessons Learned In The Golden Age Of Bio-Logging, Emily A. Mckinnon, Oliver P. Love Oct 2018

Ten Years Tracking The Migrations Of Small Landbirds: Lessons Learned In The Golden Age Of Bio-Logging, Emily A. Mckinnon, Oliver P. Love

Great Lakes Institute for Environmental Research Publications

In 2007, the first miniature light-level geolocators were deployed on small landbirds, revolutionizing the study of migration. In this paper, we review studies that have used geolocators to track small landbirds with the goal of summarizing research themes and identifying remaining important gaps in understanding. We also highlight research and opportunities using 2 recently developed tracking technologies: archival GPS tags and automated radio-telemetry systems. In our review, we found that most (54%) geolocator studies focused on quantifying natural history of migration, such as identifying migration routes, nonbreeding range, and migration timing. Studies of behavioral ecology (20%) uncovered proximate drivers of …
