Review Of Great Plains Birds, By Larkin Powell, William E. Jensen

The Prairie Naturalist

Biologists who live in the Great Plains of North America know well the general aspersion cast toward our regional home by those unfamiliar with the region and its natural treasures. Larkin Powell alludes to this all-too-common aspersion and diplomatically dispels it in his ornithological showcase of the Great Plains, simply titled Great Plains Birds. The book is a nice, quick read and a well-composed profile of the region’s avian biogeographical history, its disruptions, conservation remedies, examples of basic bird biology, and tips on how to enjoy the bird life on display in this dynamic region. Having been an ornithologist …

A New Species Of Kochius From Avra Valley, Southern Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey, Lawrence L. C. Jones, Brandon Myers

Euscorpius

A new scorpion species, Kochius colluvius sp. n. is described (Scorpiones: Vaejovidae). This small brown species is found in the Avra Valley near Tucson, Arizona, USA. It appears to be most similar to Kochius sonorae (Williams, 1971) and K. hirsuticauda (Banks, 1910). On all fingers examined, the fixed finger has 6 ID denticles and the movable finger has 7. There is no scalloping of the chela fingers. This species differs from all other vaejovids in Arizona by having a coarsely granulated exoskeleton.

Wildlife Survey Of National Parks To Assess Reptilian Biodiversity, Ajk, Jibran Haider, Inayatullah Malik, Sabiha Shamim

Journal of Bioresource Management

The class Reptilia belongs to phylum Chordata. This group forms a large community of the land vertebrates. However, they remain relatively under-examined. Roll et al. (2017) studied the global distribution of more than 10,000 reptiles. Nearly194 reptilian species have been reported from Pakistan (WWF, n.d.). Five protected parks were studied from February 2008 to May 2010. Dhirkot Nature Reserve (DNR), Banjosa Nature Reserve (BNR), Tolipir National Park (TNP), Pir Chanasi National Park (PCNP) and Pir Lasura National Park (PLNP) were considered. Fifteen species of reptiles were observed in TNP. Ten species of reptiles were recorded from PCNP. Ten species of …

Berberidaceae From Moist Temperate Forests, Northern Areas, Pakistan, Nafeesa Hanif Qudsia, Kishwar Sultana, Safdar Ali Shah

Journal of Bioresource Management

A quick visit of the protected forests of Banjosa, Dhirkot, Pir Chanasi, Pir Lassura and Tolipir was carried out. Berberidaceae belong to a family also known as the Barberry family (Elpel, n.d.). In Pakistan, there are 3 genera and 22 species belonging to this group (Jafri, n.d.). Species of this family are extensively cultivated due to their aesthetic and medicinal value. In the past, researchers would consider this family to get an idea about the habitat degradation of temperate areas. This study was aimed to produce a comprehensive list of species richness of this family in five National Parks of …

Cercarial Parasitism Of Freshwater Snails In Sandhills Ponds Versus Streams, Caroline Emily Spethman

Honors Program: Senior Projects (Public)

Parasite prevalence was calculated for all aquatic snails collected from four freshwater localities in Western Nebraska from Summer 2016 to 2019: Dunwoody Pond, Haythorn Ranch, Neven’s Restoration, and Breen’s Flyaway. With data of increasing trematode cercarial infection specifically at Dunwoody Pond, this community was further studied. In Summer 2019, a total of 217 freshwater snails representing species of Physa sp., Stagnicola elodes (Say,1821), and Helisoma anceps (Menke,1830) were collected from Dunwoody Pond and Dunwoody stream, near Ogallala, Nebraska. Eighty-one snails were collected from Dunwoody Pond, 76 snails were collected 31 meters upstream, and 60 snails were collected 61 meters upstream …

The adult male of Euscorpius feti Tropea, 2013 (Euscorpiidae) is described for the first time. A large series (45 specimens including the type material) has been studied, most of the material previously unpublished. E. feti has been found in as many as 17 caves in Croatia and Bosnia-Herzegovina, including the Adriatic islands, which makes it the most common Euscorpius species so far found in caves. Ecological notes on this species are presented.

Founders Of Plant Ecology: Frederic And Edith Clements, Jon H. Oberg

University of Nebraska State Museum: Staff and Affiliates, Publications

Nineteenth-century students of Charles Bessey at the University of Nebraska, Frederic Clements and Edith Schwartz received doctorates in botany, married, and went on to become founders of the discipline of plant ecology. They tested and taught their theory of plant succession, known as Clementsian ecology, for nearly four decades at their Alpine laboratory in Colorado. Their leadership and influence at the Carnegie Institution was world-wide and attracted followers from several other disciplines. They advocated land use measures to combat the Dust Bowl in the 1930s. Clementsian ecology is still recognized as a paradigm against which other theories of nature are …

The Distribution And Demography Of The Invasive Pacific Oyster, Crassostrea Gigas, And Native Olympia Oyster, Ostrea Lurida, In The San Diego River, Jason Langevin

Theses

Even though the introduction of the Pacific Oyster, Crassostrea gigas, to the west coast of North America, happened roughly a century ago, it has only been in the past 15 to 20 years that C. gigas has started to become an established and conspicuous species along Southern California’s coast. The establishment of C. gigas in Southern California has the potential to heavily influence many native species, as it has done globally. In Southern California, this invasion is particularly relevant for the native Olympia Oyster, Ostrea lurida. The Olympia oyster has both historical and present-day threats to its population, …

Predictors Of Bat Species Richness Within The Islands Of The Caribbean Basin, Justin D. Hoffman, Gabrielle Kadlubar, Scott C. Pedersen, Roxanne J. Larsen, Peter A. Larsen, Carleton J. Phillips, Gary G. Kwiecinski, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Several mechanisms have been shown to influence species richness among island ecosystems, yet most studies limit their focus to a few predictor variables. The objective of this study is to investigate variation in Chiropteran richness across islands in the Caribbean Basin with an extensive set of predictor variables. Using recent faunal surveys, the most contemporary list of bat species per island was complied. Data were collected on 17 predictor variables, which summarized five general island characteristics including island area, isolation, habitat diversity, human impact, and climate. An information-theoretic approach was used by fitting alternative candidate models to determine which variable(s) …

The paper builds on the 2018 obituary authored by Hugh Genoways and others that was published in the Journal of Mammalogy, but includes a much more quantitative and …

The Neotropical Variegated Squirrel, Sciurus Variegatoides (Rodentia: Sciuridae) In Nicaragua, With The Description Of A New Subspecies, Hugh H. Genoways, Robert M. Timm

University of Nebraska State Museum: Mammalogy Papers

The Neotropical variegated squirrel, Sciurus variegatoides, is represented in Nicaragua by five known subspecies—adolphei, belti, boothiae, dorsalis, and underwoodi. Analyses of morphometrics, color, and color patterns of 394 specimens from throughout the country and all available literature support the retention of these subspecies, but also reveal the presence of a sixth population of these squirrels, which is worthy of description and recognition as a new subspecies. This new subspecies is confined to Isla de Ometepe in Lago de Nicaragua. Variegated squirrels on Ometepe are on average the smallest variegated squirrels in the country …

Artful Nature And The Legacy Of Maria Sibylla Merian, Emily N. Roush, Shannon R. Zeltmann, Felicia M. Else, Kay Etheridge, Shannon Egan

Schmucker Art Catalogs

The exhibition Artful Nature and the Legacy of Maria Sibylla Merian celebrates the skills and influences of a remarkable woman from seventeenth-century Europe. Curated by Emily Roush ’21 and Shannon Zeltmann ’21 with the guidance of Professors Kay Etheridge (Biology) and Felicia Else (Art History), Emily and Shannon selected the prints, organized them into categories, and carried out research on them, much of which was relatively obscure and would have been challenging even for graduate students.

Maria Sibylla Merian lived and worked in a time of vibrant intersections of art and science in Europe. Her images of insects and plants …

The Diversity And Distribution Of Spiders (Arachnida: Araneae) Along An Outdoor – Indoor Habitat Gradient: Preliminary Findings From Piedmont Virginia, William Kish, Sujan Henkanaththegedara

Virginia Journal of Science

Although the United States supports a considerable diversity of spiders, some aspects of spider habitat use and niche specialization are poorly documented. Specifically, little attention has been given to explore how urban development affects the diversity and abundance of arthropods. We sampled spiders along an outdoor – indoor habitat gradient at Longwood University to understand the impact of urbanization on species diversity and abundance. We found 50 taxa of spiders belonging to 43 genera and 16 families. Overall, the most abundant spider family across three sampling sites was Araneidae (orb-weavers; 18.2%) followed by Lycosidae (wolf spiders; 14.8%), Salticidae (jumping spiders; …

Rose-Ringed Parakeets, Page E. Klug, William P. Bukoski, Aaron B. Shiels, Bryan M. Kluever, Shane R. Siers

Wildlife Damage Management Technical Series

Rose-ringed parakeets (Psittacula krameri; hereafter RRPA; Figure 1) are an invasive species in the United States, present in Alabama, Louisiana, Texas, and Virginia, and with established populations in California, Florida, and Hawaii. They are also the most successful species of invasive parakeet, worldwide. RRPA can cause significant damage to agriculture, including grains, oilseeds, fruits, and ornamental plants. Large flocks of RRPA roost near human infrastructure resulting in concerns about human health and safety (e.g., collisions with aircraft, disease transmission, feces accumulation, and noise complaints). The population growth and spread of RRPA is of conservation concern given the potential impact on …

Global Conservation Status And Threat Patterns Of The World’S Most Prominent Forage Fishes (Teleostei, Clupeiformes), Tiffany L. Birge

Biological Sciences Theses & Dissertations

Conserving biodiversity is one of the greatest ethical responsibilities and challenges humans face. Understanding the conservation status of taxonomic groups provides a systematic way to prioritize efforts to combat biodiversity loss. The 405 species within the order Clupeiformes are the herrings, shads, sardines, anchovies, menhadens and relatives that include many of the most important marine forage fishes. These small, schooling fishes are economically, ecologically and culturally significant globally. Despite their contribution to global fisheries and our increasing reliance on these fishes for food and industrial commodities, they are generally poorly known with limited information regarding basic biology and population trends. …

Reorganization Of Surviving Mammal Communities After The End-Pleistocene Megafaunal Extinction, Anikó B. Tóth, S. Kathleen Lyons, W. Andrew Barr, Anna K. Behrensmeyer, Jessica L. Blois, René Bobe, Matt Davis, Andrew Du, Jussi T. Eronen, J. Tyler Faith, Danielle Fraser, Nicholas J. Gotelli, Gary R. Graves, Advait M. Jukar, Joshua H. Miller, Silvia Pineda-Munoz, Laura C. Soul, Amelia Villaseñor, John Alroy

School of Biological Sciences: Faculty Publications

Large mammals are at high risk of extinction globally. To understand the consequences of their demise for community assembly, we tracked community structure through the end- Pleistocene megafaunal extinction in North America.We decomposed the effects of biotic and abiotic factors by analyzing co-occurrence within the mutual ranges of species pairs. Although shifting climate drove an increase in niche overlap, co-occurrence decreased, signaling shifts in biotic interactions. Furthermore, the effect of abiotic factors on cooccurrence remained constant over time while the effect of biotic factors decreased. Biotic factors apparently played a key role in continental-scale community assembly before the extinctions. Specifically, …

Using Single-Cell Sorting, Fish And 13c-Labeling To Cultivate And Assess Carbon Substrate Utilization Of ‘Aigarchaeota’ And Other Novel Thermophiles, Damon Kurtis Mosier

Electronic Theses, Projects, and Dissertations

‘Aigarchaeota’, a deeply branching lineage in the domain Archaea with no cultivated representatives, includes both thermophilic and hyperthermophilic microorganisms that reside in terrestrial and marine geothermal environments. The ‘Aigarchaeota’ consists of at least nine proposed genus-level groups that have been confirmed via 16S rRNA sequencing, with ‘Aigarchaeota’ Group 1 (AigG1) being the focus of this study. Based on cultivation-independent genomic data available from several AigG1 members in Great Boiling Spring (GBS), NV, and Yellowstone National Park, 22 different types of growth media were designed and tested for their ability to support growth of AigG1. One of these cultures, G1-10, was …

Information Resources For Animal Control And Wildlife Damage Management, Stephen M. Vantassel, Michael W. Fall, Serge Lariviére

Wildlife Damage Management Technical Series

A bumper sticker reads, “If you think education is expensive, you oughta try ignorance.” That statement could not be truer in regard to wildlife damage management. Being willing to learn is a critical attitude for everyone involved in wildlife damage management. Since wildlife damage management intersects so many other disciplines, no single person can be an expert in all of them. In addition, the arrival of an invasive species, changes in building practices (e.g., egress windows, ridge vents), or the implementation of new regulations can confound traditional practices and require new control methods. Thus, it is important to provide a …

Isolation Of Caldatribacterium (Op9) And Investigation Of Its Potential Interactions With A Novel, Co-Cultivated Thermodesulfobacterium Species, Toshio Alvarado

Electronic Theses, Projects, and Dissertations

Atribacteria (OP9), candidate phylum with no representatives in pure culture, is found in various anaerobic environments worldwide. “Caldatribacterium”, a lineage within Atribacteria that is predicted to be a strictly anaerobic sugar fermenter based on cultivation-independent genomic analyses, is currently being maintained in lab enrichment cultures with fucose as its sole growth substrate. Metagenomics and 16S rRNA gene tag sequencing indicated that the fucose culture was a co-culture of “Caldatribacterium” and an uncultivated member of the genus Thermodesulfobacterium. Due to failed attempts to isolate “Caldatribacterium” by dilution-to-extinction and plating, it was hypothesized that “Caldatribacterium” is dependent in some way on the …

Systematics Of Carex Section Laxiflorae (Cyperaceae), Jenna Dorey

Dissertations, Theses, and Capstone Projects

Carex, with more than 2100 species, is the most species-rich genus of flowering plants in temperate regions of the world. Members of the family Cyperaceae are colloquially known as sedges, and members of the genus Carex are called “true sedges.” Carex occur on every continent except for Antarctica, they thrive in a panoply of habitats, and are ecologically important as a forage source for wildlife, carbon sequestration, prevention of soil erosion, and providing habitat for fresh water invertebrates. Despite their importance many sedges are still poorly known, such as the woodland sedges in Carex section Laxiflorae, which is …

A New Species Of Catalinia Soleglad Et Al., 2017 (Scorpiones: Vaejovidae) From Southern California, Usa, Rolando Teruel, Brandon Myers

Euscorpius

Herein we describe a new species of the vaejovid scorpion genus Catalinia Soleglad, Ayrey, Graham & Fet, 2017. It was collected in a single locality of the northwestern foothills of the Santa Ana Mountains. It is most closely related to both Catalinia andreas (Gertsch & Soleglad, 1972) and C. minima (Kraepelin, 1911), but is clearly distinguished by tegumentary sculpture, morphometric ratios and pectinal tooth counts. The new species is described and illustrated in detail, with some ecological data included; moreover, a minor correction is introduced to the diagnosis of the genus.
