Notes On Reproduction, Seasonality, And Roost Sites For Silver-Haired Bats (Lasionycteris Noctivagans) In Western Nebraska, Joseph W. Paysen, Dawson V. Kosmicki, Keith Geluso

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Silver-haired Bats (Lasionycteris noctivagans) are a migratory species found throughout the United States, southern Canada, and northern Mexico. Throughout their range, Silver-haired Bats roost in various tree species, generally within decaying features like cavities and exfoliated bark. Herein we report on additional reproductive and seasonal data as well as the first data on trees used as roost sites by Silver-haired Bats in Nebraska. We captured individuals along a small tributary of the North Platte River at Ash Hollow State Historical Park, Garden County, Nebraska, and tracked bats to their roosts. At this location, we documented lactation on 17 …

Attributes Of Artificial Wetlands Colonized By Ambystoma Maculatum On A Virginia Surface Mine, Hunter Hill, Garrett Stiltner, Walter H. Smith

Virginia Journal of Science

Landscapes impacted by surface mineral extraction present a range of artificial wetland habitats potentially useable by pool-breeding amphibians, although little information exists in the literature detailing which attributes influence breeding site selection by wetland amphibian specialists in post-mined landscapes. We compared attributes of artificial wetlands consistently used and unused as oviposition sites by Spotted Salamanders (Ambystoma maculatum) over a six-year period on a 120-ha former surface mine in Wise County, Virginia, USA. Salamanders non-randomly selected wetlands as oviposition sites, with one-third of available wetlands within the study area showing evidence of ovipositioning. Wetlands used as breeding sites were …

Two New Species Of Uroplectes Peters, 1861 (Scorpiones, Buthidae) From Somaliland And Mozambique, František Kovařík

Euscorpius

Two new species, Uroplectes elmii sp. n. from Somaliland and U. mossambicensis sp. n. from Mozambique are described, fully illustrated with color photos showing their morphology. Both species are similar to Uroplectes fischeri (Karsch, 1879) from which they differ mainly in finger dentition (Uroplectes elmii sp. n.) and strongly reduced tibial spurs on legs III–IV (U. mossambicensis sp. n.). Uroplectes elmii sp. n. is also compared with U. pardii Kovařík, 2003, from which it differs mainly by extremely reduced to absent metasomal punctation. A distribution map of all …

Alpiscorpius Huyukensis Sp. N., An Unexpected New Species From Sultan Mountains, Konya Province, Turkey (Scorpiones: Euscorpiidae), Ersen A. Yağmur, Halil İ. Yaylı

Euscorpius

A new scorpion species, Alpiscorpius huyukensis sp. n., is described from the western foothills of the Sultan Mountains, Konya Province, in the Aegean Region of western Turkey, based on morphological characters. The species is assigned to the genus Alpiscorpius Gantenbein et al., 1999, due to the presence of three trichobothria in the em series on the external surface of the pedipalp patella. A. huyukensis sp. n. can be readily distinguished from its all congeners by its yellowish-orange or greyish-orange body and yellow metasomal coloration, the fifth metasomal segment bearing distinct ventrolateral carinae, the presence of six trichobothria in the …

The Genus Androctonus Ehrenberg, 1828 (Scorpiones: Buthidae) In Oman, Graeme Lowe

Euscorpius

The taxonomic position of Androctonus populations in Oman was investigated by analyzing morphological variation in a comprehensive sample representing 150 records gathered from 95 localities spread throughout the country. Two new allopatric species are described, separated by multivariate morphometric analysis and meristic characters: (1) A. omanensis sp. n., distributed across most of Oman, is characterized by wider, deeper metasomal segments IV–V, shorter legs, more robust pedipalps, more granules on lateral inframedian carinae of metasoma II–III, and sparser setation on basitarsal spurs; and (2) A. ammophilus sp. n., distributed in the dunes of the Rub’ al-Khali (Empty Quarter) of …

Predation Of Aegaeobuthus Nigrocinctus (Ehrenberg, 1828) (Scorpiones: Buthidae) By A Middle East Black Tarantula, Chaetopelma Olivaceum (C. L. Koch, 1841) (Araneae: Theraphosidae) In Lebanon, Rami Khashab

Euscorpius

I report the first documented case of the buthid scorpion Aegaeobuthus nigrocinctus (Ehrenberg, 1828) serving as prey for the tarantula Chaetopelma olivaceum (C. L. Koch, 1841) in Lebanon. The observation was made during a nocturnal survey in the Mount Lebanon region. The case contributes to the limited records of tarantula predation on scorpions and underscores the role of prey-predator size asymmetry in facilitating high-risk predation among arachnids.

Exploring The Role Of Ecological Traits In Shaping Spatial Patterns Of Genetic Diversity, Rilquer Mascarenhas Da Silva

Dissertations, Theses, and Capstone Projects

The field of comparative phylogeography aims at uncovering common underlying causes for shared patterns of diversity and diversification at the population level. However, it is now widely accepted that intraspecific genetic diversity patterns can differ considerably across co-occurring taxa due to ecological processes acting at the population level (and influencing individual movement and abundance). To model the processes underlying lineage diversification and demographic shifts in response to environmental changes, phylogeographers and population geneticists are now faced with the challenge of incorporating measurements of species ecological traits into their molecular studies. This dissertation aimed at investigating how different types of ecological …

Abiotic Factors Influencing Anuran Occupation Of Neotropical Brazilian Caves, Vinícius F. Sperandei, Willian Vaz-Silva, Tejerina-Garro L. Francisco

International Journal of Speleology

Despite increasing research on the Neotropical underground environment, anurans remain poorly understood in this habitat. It was analyzed scientific literature records of anurans in Brazilian natural caves and performed a redundancy analysis (RDA) to identify the environmental, taxonomic, geographic, geological and land-use variables that influence their cave occupancy. It was examined a total of 247 literature records, encompassing 83 species/morphospecies, which revealed distinct cave-dwelling tendencies. Some anuran species occupy caves at altitudes between 5 to 21 meters above sea level (m asl), in areas characterized by rocky outcrops and grassland. Others are associated with caves surrounded by forest, savanna, pasture …

Economic Analysis Of Stockers Grazing Botanically Diverse Summer Annual Pasture, Kelly M. Mercier, Christopher D. Teutsch, S. Ray Smith, Kenneth H. Burdine, Eric S. Vanzant, Edwin L. Ritchey

Journal of Extension

Economic analyses were performed to determine the feasibility of retaining weaned fall-born calves on summer annual pastures (a monoculture, a 3-species mixture, or a 12-species mixture). Average daily gain was reduced by 0.3 lbs/day in calves grazing the complex mixture in two out of three years. Enterprise budgeting illustrated that retaining calves on summer annual forages was not economical. Two-way net return tables indicated that this scenario would only be profitable when cattle prices are high and pasture establishment costs are low. Extension educators should be sure to emphasize the economic risks when discussing these systems.

Isolation And Divergence Of Greater Earless Lizards (Phrynosomatidae: Cophosaurus) In Western North America Support Multiple Diversification Processes And A Complex Demographic History, Christopher Robert Blair, Carlos Joaquín Pavón-Vázquez, Qaantah Rana, Keaka Farleigh, Erika Crispo, Thomas Panzera, Felipe De Medeiros Magalhães, Britt White, Uri Omar Garcia-Vazquez

Publications and Research

The Southwestern US and northern Mexico continue to serve as ideal regions to elucidate the suite of ecological and evolutionary processes influencing lineage diversification. The complex geological history of arid North America, coupled with paleoclimate change during the Pleistocene and diverse ecoregions makes a multipronged approach to hypothesis testing necessary. We combine thousands of loci from a genotyping-by-sequencing (GBS) approach along with mitochondrial DNA (mtDNA) sequences from the Greater Earless Lizard (Cophosaurus texanus) to examine diversity and test for cryptic population structure. We also apply recently developed coalescent approaches in a Bayesian framework to estimate migration rates. Population …

Snake Spirits, Fishermen And Water Birds On Lake Victoria: A Case Study Of Cultural Conservation In The Musambwa Islands, Uganda, And Prospects For Tourism To Improve Local Livelihoods, Joel T. Heinen, Henry Batenda

Journal of Ecological Anthropology

Abstract.

Using a combination of site visits, document reviews, focus group and key informant surveys of fishermen, we explore the cultural beliefs, taboos and norms that protect Musambwa Islands, Uganda. The islands form part of a large protected wetland with nesting habitat for thousands of water birds and a large population of highly-venomous forest cobras that coexist in and around fishermen dwellings. There are strong taboos against cutting trees, allowing women on the island, and harming cobras. We present some of our ideas on how to improve the economic situation of fishermen through the promotion of nature-based and cultural tourism …

Abundance, Distribution, And Shoaling Of Driftfishes And Allies (Scombriformes: Stromateoidei) In The Pelagic Gulf Of Mexico, Juliet Tretler

All HCAS Student Capstones, Theses, and Dissertations

The suborder Stromateoidei contains 80 species of mesopelagic fishes in five families distributed throughout temperate and tropical seas worldwide, including the Gulf of Mexico (Gulf hereafter). Mesopelagic fishes, especially those that spatially aggregate, serve as important forage items for commercially, recreationally, and ecologically important species of fish, marine mammals, and seabirds. However, knowledge of the ecology and trophic importance of stromateoid fishes in the Gulf is extremely limited. This study provides quantitative information on the species composition, abundance, distribution, and biomass contribution of the stromateoid species to the Gulf deep-pelagic fish assemblage, with comparison to “archetypal” mesopelagic fish families (e.g., …

Temporal Partitioning And Coexistence Among Four Sympatric Felid Species In The Northern Jaguar Reserve, Kylie Marie Rezendes

Open Access Theses & Dissertations

Coexistence among sympatric carnivores is shaped by behavioral strategies that mediate competition and mortality risk in heterogeneous landscapes. Understanding how sympatric carnivores, such as felids, use space and time in relation to one another requires models that account for both spatial and temporal overlap across landscapes. Models incorporating time-to-event probabilities provide a powerful framework for detecting behavioral dynamics across shared landscapes. This study evaluated the spatiotemporal responses of two apex predators â?? the jaguar (Panthera onca) and mountain lion (Puma concolor) - and two mesopredators - bobcat (Lynx rufus) and ocelot (Leopardus pardalis) - across five years of camera trap …

Distributional Records Of Blanding’S Turtles (Emydoidea Blandingii) In Nebraska, Sam Thede, Dan Fogell, Keith Geluso

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Blanding’s Turtle (Emydoidea blandingii) is a species of concern in North America as many populations have declined across its distribution. Environmental factors associated with alteration of natural ecosystems have played a role in declines leading to many isolated populations. Most populations exist in the Great Lakes region with a number of outlying populations, such as Nebraska. Understanding the current distribution of the species will facilitate regional management strategies to protect this species into the future. In Nebraska, Blanding’s Turtles were known from 23 counties prior to this study. Herein, we report on eight new county records, five (Blaine, …

Coral reefs are one of Earth’s most vital and threatened ecosystems. They protect coastlines, generate billions of dollars of tourism revenue, support valuable fisheries, and contribute to the development of vital medicines. Yet half of the world's coral reefs have been lost in the last 50 years, and 90% of remaining reefs are projected to die off by the middle of this century, mainly due to warming seas from climate change.

Despite these challenges there is reason for hope. Some coral reefs – such as in the northern Red Sea and Gulf of Aqaba – have demonstrated remarkable resilience to …

One Health Interventions And Challenges Under Rural African Smallholder Farmer Settings: A Scoping Review, Evanson R. Omuse, Honest Machekano, Bonoukpoè M. Sokame, Daniel M. Mutyambai, Thomas Dubois, Sevgan Subramanian, Frank Chidawanyika

All Peer-Reviewed Publications

The global human population is rapidly increasing, escalating interactions of people, animals and the environment. This has led to more convoluted health challenges, for which African smallholder farmers bear the brunt. The One Health (OH) approach recognises the interconnectedness of these health challenges and thus follows a transdisciplinary approach involving diverse stakeholders to address them. Although there have recently been global concerted efforts and studies on OH, an information gap exists in Africa, particularly regarding smallholder farmers and their needs. Additionally, evaluation frameworks and outcome metrics for OH initiatives are still unclear. Thus, this study was conducted to critically map …

Ecospiritual Entanglement, Ali Vedad Yüner

Masters Theses

Land breeds culture. It gives us the resources to thrive, and in that process we establish a relationship with its constituents. With a multitude of beings inhabiting the land, a complex web of relationships develop. Biology describes these relationships as food webs; the mass entanglement of organisms in a manner that each organism nourishes the other. These webs are not just mere scientific structures but rather an interpretation of existential connections that every organism in the world, humans included, are indebted to. Food webs are the first stepping stone in the formation of culture, as they account for the engagement …

Field Journal: The Excluded Middle, Carrie E. Kouts

Masters Theses

What does it look like to engage with organisms and landscapes at the periphery of anthropocentric value structures? How does one break the internalized myth that the “built” environment is excluded from the natural world? When does a hyper-mobile and hyper-commodified society confront the exponential crisis of animal death? Within this series of journal entries, field notes, collection observations, weird prose, and sensory musings, one will find questions on the nature of being human and the complex narratives of care we encounter in a world shared with more-than-humans. Each handwritten vignette and photograph from daily life weaves a non-linear and …
