Whose Water Is It Anyway? Comparing The Water Rights Frameworks Of Arkansas, Oklahoma, Texas, New Mexico, Georgia, Alabama, And Florida, M. D. Smolen, Aaron R. Mittelstet, Bekki Harjo

Department of Agricultural and Biological Systems Engineering: Faculty Publications

In most states surface waters, (streams, lakes, and coastal waters) are owned by the public. On the other hand, ground water may be privately or publicly owned. Because all waters are linked through the hydrologic cycle, and the hydrologic cycle is not confined within any geographic or political boundary, the question of ownership is generally replaced by one of who has the right to manage, divert, use, or sell the water.

Breast cancer is a commonly diagnosed cancer among women in the United States. It is estimated that 230,480 women were diagnosed with, and 39,520 women died from, breast cancer in 2011 in the United States.¹ Basal-like breast cancer accounts for 15% of all breast cancers and has a poor prognosis. The majority of these cancers are referred to as triple-negative breast cancers because they do not over express estrogen receptor, progesterone receptor, or human epidermal growth factor receptor 2.^2,3 Chemotherapy is an effective option to treat such cancers; however, chemotherapy is always associated with several sets of side …

Udp-Glucose Dehydrogenase Polymorphisms From Patients With Congenital Heart Valve Defects Disrupt Enzyme Stability And Quaternary Assembly, Annastasia S. Hyde, Erin L. Farmer, Katherine E. Easley, Kristy Van Lammeren, Vincent M. Christoffels, Joseph J. Barycki, Jeroen Bakkers, Melanie A. Simpson

Department of Biochemistry: Faculty Publications

Background: UDP-glucose dehydrogenase (UGDH) polymorphisms were identified in a screen of candidate genes for heart valve defects.

Results: Two individual mutants fail to rescue cardiac valve defects in UGDH-deleted zebrafish and have reduced stability in vitro.

Conclusion: UGDH loss of function mutations result in a subset of human congenital cardiac valve defects caused by reduced enzyme activity during morphogenesis.

Significance: Screening these alleles could predict valve defects.

Small But Crucial: The Novel Small Heat Shock Protein Hsp21 Mediates Stress Adaptation And Virulence In Candida Albicans, Francois L. Mayer, Duncan Wilson, Ilse D. Jacobsen, Pedro Miramón, Silvia Slesiona, Iryna Bohovych, Alistair J.P. Brown, Bernhard Hube

Department of Biochemistry: Faculty Publications

Small heat shock proteins (sHsps) have multiple cellular functions. However, the biological function of sHsps in pathogenic microorganisms is largely unknown. In the present study we identified and characterized the novel sHsp Hsp21 of the human fungal pathogen Candida albicans. Using a reverse genetics approach we demonstrate the importance of Hsp21 for resistance of C. albicans to specific stresses, including thermal and oxidative stress. Furthermore, a hsp21∆/∆ mutant was defective in invasive growth and formed significantly shorter filaments compared to the wild type under various filamentinducing conditions. Although adhesion to and invasion into human-derived endothelial and oral epithelial cells …

Oligomerization Of Heme O Synthase In Cytochrome Oxidase Biogenesis Is Mediated By Cytochrome Oxidase Assembly Factor Coa2, Oleh Khalimonchuk, Hyung Kim, Talina Watts, Xochitl Perez-Martinez, Dennis R. Winge

Department of Biochemistry: Faculty Publications

The synthesis of the heme a cofactor used in cytochrome c

oxidase (CcO) is dependent on the sequential action of heme o

synthase (Cox10) and heme a synthase (Cox15). The active state of

Cox10 appears to be a homo-oligomeric complex,andformation of

this complex is dependent on the newly synthesized CcO subunit

Cox1 and the presence of an early Cox1 assembly intermediate.

Cox10 multimerization is triggered by progression of Cox1 from

the early assembly intermediate todownstreamintermediates.The

CcOassembly factor Coa2 appears important in coupling the presence

of newly synthesized Cox1 to Cox10 oligomerization. Cells

lacking Coa2 are impaired in Cox10 complex formation …

Selective Oma1 Protease-Mediated Proteolysis Of Cox1 Subunit Of Cytochrome Oxidase In Assembly Mutants, Oleh Khalimonchuk, Mi-Young Jeong, Talina Watts, Elliott Ferris, Dennis R. Winge

Department of Biochemistry: Faculty Publications

Background: Yeast lacking Coa2 are deficient in cytochrome c oxidase due to Cox1 degradation.

Results: Oma1 mediates Cox1 degradation in coa2∆ cells but not other mutants stalled in oxidase biogenesis.

Conclusion: Impaired hemylation of Cox1 in coa2∆ cells leads to misfolding and facile degradation by Oma1.

Significance: Oma1 functions in quality control of cytochrome oxidase assembly.

Role Of Apoptosis-Inducing Factor, Proline Dehydrogenase, And Nadph Oxidase In Apoptosis And Oxidative Stress, Sathish Kumar Natarajan, Donald F. Becker

Department of Biochemistry: Faculty Publications

Flavoproteins catalyze a variety of reactions utilizing flavin mononucleotide or flavin adenine dinucleotide as cofactors. The oxidoreductase properties of flavoenzymes implicate them in redox homeostasis, oxidative stress, and various cellular processes, including programmed cell death. Here we explore three critical flavoproteins involved in apoptosis and redox signaling, ie, apoptosis-inducing factor (AIF), proline dehydrogenase, and NADPH oxidase. These proteins have diverse biochemical functions and influence apoptotic signaling by unique mechanisms. The role of AIF in apoptotic signaling is two-fold, with AIF changing intracellular location from the inner mitochondrial membrane space to the nucleus upon exposure of cells to apoptotic stimuli. In …

Late-Stage Maturation Of The Rieske Fe/S Protein: Mzm1 Stabilizes Rip1 But Does Not Facilitate Its Translocation By The Aaa Atpase Bcs1, Tie-Zhong Cui, Pamela M. Smith, Jennifer L. Fox, Oleh Khalimonchuk, Dennis R. Winge

Department of Biochemistry: Faculty Publications

The final step in the assembly of the ubiquinol-cytochrome c reductase or bc₁ complex involves the insertion of the Rieske Fe/S cluster protein, Rip1. Maturation of Rip1 occurs within the mitochondrial matrix prior to its translocation across the inner membrane (IM) in a process mediated by the Bcs1 ATPase and subsequent insertion into the bc₁ complex. Here we show that the matrix protein Mzm1 functions as a Rip1 chaperone, stabilizing Rip1 prior to the translocation step. In the absence of Mzm1, Rip1 is prone to either proteolytic degradation or temperature-induced aggregation. A series of Rip1 truncations were engineered …

Substrate Channeling In Proline Metabolism, Benjamin W. Arentson, Nikhilesh Sanyal, Donald F. Becker

Department of Biochemistry: Faculty Publications

Proline metabolism is an important pathway that has relevance in several cellular functions such as redox balance, apoptosis, and cell survival. Results from different groups have indicated that substrate channeling of proline metabolic intermediates may be a critical mechanism. One intermediate is pyrroline-5-carboxylate (P5C), which upon hydrolysis opens to glutamic semialdehyde (GSA). Recent structural and kinetic evidence indicate substrate channeling of P5C/ GSA occurs in the proline catabolic pathway between the proline dehydrogenase and P5C dehydrogenase active sites of bifunctional proline utilization A (PutA). Substrate channeling in PutA is proposed to facilitate the hydrolysis of P5C to GSA which is …

Glutaredoxin 1 Protects Dopaminergic Cells By Increased Protein Glutathionylation In Experimental Parkinson's Disease, Humberto Rodriguez-Rocha, Aracely Garcia Garcia, Laura Zavala-Flores, Sumin Li, Nandakumar Madayiputhiya, Rodrigo Franco

Department of Biochemistry: Faculty Publications

Aims: Chronic exposure to environmental toxicants, such as paraquat, has been suggested as a risk factor for Parkinson's disease (PD). Although dopaminergic cell death in PD is associated with oxidative damage, the molecular mechanisms involved remain elusive. Glutaredoxins (GRXs) utilize the reducing power of glutathione to modulate redox-dependent signaling pathways by protein glutathionylation. We aimed to determine the role of GRX1 and protein glutathionylation in dopaminergic cell death. Results: In dopaminergic cells, toxicity induced by paraquat or 6-hydroxydopamine (6-OHDA) was inhibited by GRX1 overexpression, while its knock-down sensitized cells to paraquat-induced cell death. Dopaminergic cell death was paralleled by protein …

Larval Performance And Kill Rate Of Convergent Ladybird Beetles, Hippodamia Convergens, On Black Bean Aphids, Aphis Fabae, And Pea Aphids, Acyrthosiphon Pisum, Travis M. Hinkelman, Brigitte Tenhumberg

School of Biological Sciences: Faculty Publications

Generalist predator guilds play a prominent role in structuring insect communities and can contribute to limiting population sizes of insect pest species. A consequence of dietary breadth, particularly in predatory insects, is the inclusion of low-quality, or even toxic, prey items in the predator’s diet. Consumption of low-quality prey items reduces growth, development, and survival of predator larvae, thereby reducing the population sizes of generalist predators. The objective of this paper was to examine the effect of a suspected low-quality aphid species, Aphis fabae (Scopoli) (Hemiptera: Aphididae), on the larval performance of an abundant North American predator, Hippodamia convergens (Guérin-Méneville) …

Urea Amidolyase (Dur1,2) Contributes To Virulence And Kidney Pathogenesis Of Candida Albicans, Dhammika H. M. L. P Navarathna, Michail S. Lionakis, Martin J. Lizak, Jeeva Munasinghe, Kenneth W. Nickerson, David D. Roberts

School of Biological Sciences: Faculty Publications

The intracellular enzyme urea amidolyase (Dur1,2p) enables C. albicans to utilize urea as a sole nitrogen source. Because deletion of the DUR1,2 gene reduces survival of C. albicans co-cultured with a murine macrophage cell line, we investigated the role of Dur1,2p in pathogenesis using a mouse model of disseminated candidiasis. A dur1,2Δ/dur1,2Δ strain was significantly less virulent than the wild-type strain, showing significantly higher survival rate, better renal function, and decreased and less sustained fungal colonization in kidney and brain. Complementation of the mutant restored virulence. DUR1,2 deletion resulted in a milder host inflammatory reaction. Immunohistochemistry, flow …

Template-Based Structure Prediction And Classification Of Transcription Factors In Arabidopsis Thaliana, Tao Lu, Yuedong Yang, Bo Yao, Song Liu, Yaoqi Zhou, Chi Zhang

School of Biological Sciences: Faculty Publications

Transcription factors (TFs) play important roles in plants. However, there is no systematic study of their structures and functions of most TFs in plants. Here, we performed template-based structure prediction for all TFs in Arabidopsis thaliana, with their full-length sequences as well as C-terminal and N-terminal regions. A total of 2,918 model structures were obtained with a high confidence score. We find that TF families employ only a smaller number of templates for DNA-binding domains (DBD) but a diverse number of templates for transcription regulatory domains (TRD). Although TF families are classified according to DBD, their sizes have a significant …

Survival Of The Fittest: Overcoming Oxidative Stress At The Extremes Of Acid, Heat And Metal, Yukari Maezato, Paul H. Blum

School of Biological Sciences: Faculty Publications

The habitat of metal respiring acidothermophilic lithoautotrophs is perhaps the most oxidizing environment yet identified. Geothermal heat, sulfuric acid and transition metals contribute both individually and synergistically under aerobic conditions to create this niche. Sulfuric acid and metals originating from sulfidic ores catalyze oxidative reactions attacking microbial cell surfaces including lipids, proteins and glycosyl groups. Sulfuric acid ����� ��������� ������������ ������������ ������������� ��� ���� ���������� ��� ������ �������� carbon. Oxidative reactions leading to abstraction of electrons is further impacted by heat through an increase in the proportion of reactant molecules with sufficient energy to react. Collectively these factors and particularly …

Divergent Functions Of The Myotubularin (Mtm) Homologs Atmtm1 And Atmtm2 In Arabidopsis Thaliana: Evolution Of The Plant Mtm Family, Yong Ding, Ivan Ndamukong, Yang Zhao, Yuannan Xia, Jean-Jack Riethoven, David R. Jones, Nullin Divecha, Zoya Avramova

School of Biological Sciences: Faculty Publications

Myotubularin and myotubularin-related proteins are evolutionarily conserved in eukaryotes. Defects in their function result in muscular dystrophy, neuronal diseases, and leukemia in humans. In contrast to the animal lineage, where genes encoding both active and inactive myotubularins (phosphoinositide 3-phosphatases) have appeared and proliferated in the basal metazoan group, myotubularin genes are not found in the unicellular relatives of green plants. However, they are present in land plants encoding proteins highly similar to the active metazoan enzymes. Despite their remarkable structural conservation, plant and animal myotubularins have significantly diverged in their functions. While loss of myotubularin function causes severe disease phenotypes …

Evolution Of Starvation Resistance In Drosophila Melanogaster: Measurement Of Direct And Correlated Responses To Artificial Selection, Tiffany E. Schwasinger-Schmidt, Stephen D. Kachman, Lawrence G. Harshman

Lawrence G. Harshman Publications

Laboratory selection for resistance to starvation has been conducted under relatively controlled conditions to investigate direct and correlated responses to artificial selection. With regard to starvation resistance, there are three physiological routes by which the trait can evolve: resource accumulation, energy conservation and starvation tolerance. A majority of energetic compounds and macromolecules including triglycerides, trehalose and other sugars, and soluble protein increased in abundance as a result of selection. Movement was additionally investigated with selected males moving less than control males and selected females exhibiting a similar response to selection. Results obtained from this study supported two of the possible …

A Peptide Photoaffinity Probe Specific For The Active Conformation Of The Abl Tyrosine Kinase, Yang Deng, Brian A. Couch, Anthony J. Koleske, Benjamin E. Turk

School of Biological Sciences: Faculty Publications

The design of sensors to monitor the activity state of specific protein kinases is challenging due to the complexity of eukaryotic kinomes. Here we describe a peptide-based photaffinity probe that specifically labels the active conformation of the Abl tyrosine kinase.

Oxygenation Properties And Oxidation Rates Of Mouse Hemoglobins That Differ In Reactive Cysteine Content, Jay F. Storz, Roy E. Weber, Angela Fago

Jay F. Storz Publications

House mice (genus Mus) harbor extensive allelic variation at two tandemly duplicated genes that encode the β-chain subunits of adult hemoglobin (Hb). Alternative haplotypes differ in the level of sequence divergence between the two β-globin gene duplicates: the Hbb^d and Hbb^p haplotypes harbor two structurally distinct β-globin genes, whereas the Hbb^s haplotype harbors two β-globin duplicates that are identical in sequence. One especially salient difference between the s-type Hbs relative to the d- and p-type Hbs relates to the number of reactive β-chain cysteine residues. In addition to the highly conserved cysteine residue …

Regulatory Changes Contribute To The Adaptive Enhancement Of Thermogenic Capacity In High-Altitude Deer Mice, Zachary A. Cheviron, Gwendolyn C. Bachman, Alex D. Connaty, Jay F. Storz

Jay F. Storz Publications

In response to hypoxic stress, many animals compensate for a reduced cellular O₂ supply by suppressing total metabolism, thereby reducing O₂ demand. For small endotherms that are native to high-altitude environments, this is not always a viable strategy, as the capacity for sustained aerobic thermogenesis is critical for survival during periods of prolonged cold stress. For example, survivorship studies of deer mice (Peromyscus maniculatus) have demonstrated that thermogenic capacity is under strong directional selection at high altitude. Here, we integrate measures of whole-organism thermogenic performance with measures of metabolic enzyme activities and genomic transcriptional profiles to …

Evolution Of The Globin Gene Family In Deuterostomes: Lineage-Specific Patterns Of Diversification And Attrition, Federico G. Hoffmann, Juan C. Opazo, David Hoogewijs, Thomas Hankeln, Bettina Ebner, Serge N. Vinogradov, Xavier Bailly, Jay F. Storz

Jay F. Storz Publications

In the Metazoa, globin proteins display an underlying unity in tertiary structure that belies an extraordinary diversity in primary structures, biochemical properties, and physiological functions. Phylogenetic reconstructions can reveal which of these functions represent novel, lineage-specific innovations, and which represent ancestral functions that are shared with homologous globin proteins in other eukaryotes and even prokaryotes. To date, our understanding of globin diversity in deuterostomes has been hindered by a dearth of genomic sequence data from the Ambulacraria (echinoderms + hemichordates), the sister group of chordates, and the phylum Xenacoelomorpha, which includes xenoturbellids, acoelomorphs, and nemertodermatids. Here, we report the results …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We present the first reconstruction of the parasitoses among the people of the Loma San Gabriel culture, as represented by 36 coprolites excavated from the Cueva de los Muertos Chiquitos in Durango, Mexico. The coprolites date to approximately 1,400-yr ago. Species identified based on eggs recovered include the trematode Echinostoma sp., the tapeworms Hymenolepis sp. and Dipylidium caninum, and the nematodes Ancylostoma duodenale, Enterobius vermicularis, and Trichuris trichiura. After rehydration and screening, 2 methods were used to recover eggs from these samples including spontaneous sedimentation and flotation. Samples were analyzed by 3 different laboratories for independent …

Return To Beringia: Parasites Reveal Cryptic Biogeographic History Of North American Pikas, Kurt E. Galbreath, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Traditional concepts of the Bering Land Bridge as a zone of predominantly eastward expansion from Eurasia and a staging area for subsequent colonization of lower latitudes in North America led to early inferences regarding biogeographic histories of North American faunas, many of which remain untested. Here we apply a host–parasite comparative phylogeographical (HPCP) approach to evaluate one such history, by testing competing biogeographic hypotheses for five lineages of host-specific parasites shared by the collared pika (Ochotona collaris) and American pika (Ochotona princeps) of North America. We determine whether the southern host species (O. princeps) …

Discovery And Description Of The "Davtiani" Morphotype For Teladorsagia Boreoarcticus (Trichostrongyloidea: Ostertagiinae) Abomasal Parasites In Muskoxen, Ovibos Moschatus, And Caribou, Rangifer Tarandus, From The North American Arctic: Implications For Parasite Faunal Diversity, Eric P. Hoberg, Arthur Abrams, Patricia A. Pilitt, Susan J. Kutz

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Collections to explore helminth diversity among free-ranging ungulates in the North American Arctic revealed the occurrence of a third male, or "davtiani," morphotype for Teladorsagia boreoarcticus. Designated as T. boreoarcticus forma (f.) minor B, the males occurred with T. boreoarcticus f. major and T. borearcticus f. minor A in endemic populations of muskoxen (Ovibos moschatus wardi) and barrenground caribou (Rangifer tarandus groenlandicus) on Victoria Island, Nunavut, Canada, and in muskoxen and Peary caribou (Rangifer tarandus pearyi) on Banks Island, Northwest Territories, Canada. These specimens differ from conspecific morphotypes in the structure …

Removing 17Β-Estradiol From Drinking Water In A Biologically Active Carbon (Bac) Reactor Modified From A Granular Activated Carbon (Gac) Reactor, Zhongtian Li, Bruce I. Dvorak, Xu Li

Department of Civil and Environmental Engineering: Faculty Publications

Estrogenic compounds in drinking water sources pose potential threats to human health. Treatment technologies are needed to effectively remove these compounds for the production of safe drinking water. In this study, GAC adsorption was first tested for its ability to remove a model estrogenic compound, 17β-estradiol (E2). Although GAC showed a relatively high adsorption capacity for E2 in isotherm experiments, it appeared to have a long mass transfer zone in a GAC column reactor, causing an early leakage of E2 in the effluent. With an influent E2 concentration of 20 μg/L, the GAC reactor was able to bring down effluent …

Occurrence, Transmission, And Zoonotic Potential Of Chronic Wasting Disease, Samuel E. Saunders, Shannon L. Bartelt-Hunt, Jason C. Bartz

Department of Civil and Environmental Engineering: Faculty Publications

Chronic wasting disease (CWD) is a fatal, transmissible prion disease that affects captive and free-ranging deer, elk, and moose. Although the zoonotic potential of CWD is considered low, identification of multiple CWD strains and the potential for agent evolution upon serial passage hinders a defi nitive conclusion. Surveillance for CWD in free-ranging populations has documented a continual geographic spread of the disease throughout North America. CWD prions are shed from clinically and preclinically affected hosts, and CWD transmission is mediated at least in part by the environment, perhaps by soil. Much remains unknown, including the sites and mechanisms of prion …

Analysis Of Bacterial Biofilms Using Nmr-Based Metabolomics, Bo Zhang, Robert Powers

Robert Powers Publications

Infectious diseases can be difficult to cure, especially if the pathogen forms a biofilm. After decades of extensive research into the morphology, physiology and genomics of biofilm formation, attention has recently been directed toward the analysis of the cellular metabolome in order to understand the transformation of a planktonic cell to a biofilm. Metabolomics can play an invaluable role in enhancing our understanding of the underlying biological processes related to the structure, formation and antibiotic resistance of biofilms. A systematic view of metabolic pathways or processes responsible for regulating this ‘social structure’ of microorganisms may provide critical insights into biofilm-related …

Muc1 Mucin Stabilizes And Activates Hypoxia-Inducible Factor 1 Alpha To Regulate Metabolism In Pancreatic Cancer, Nina V. Chaika, Teklab Gebregiworgis, Michelle E. Lewallen, Vinee Purohit, Prakash Radhakrishnan, Xiang Liu, Bo Zhang, Kamiya Mehla, Roger B. Brown, Thomas Caffrey, Fang Yu, Keith R. Johnson, Robert Powers, Michael A. Hollingsworth, Pankaj K. Singh

Robert Powers Publications

Aberrant glucose metabolism is one of the hallmarks of cancer that facilitates cancer cell survival and proliferation. Here, we demonstrate that MUC1, a large, type I transmembrane protein that is overexpressed in several carcinomas including pancreatic adenocarcinoma, modulates cancer cell metabolism to facilitate growth properties of cancer cells. MUC1 occupies the promoter elements of multiple genes directly involved in glucose metabolism and regulates their expression. Furthermore, MUC1 expression enhances glycolytic activity in pancreatic cancer cells. We also demonstrate that MUC1 expression enhances in vivo glucose uptake and expression of genes involved in glucose uptake and metabolism in orthotopic implantation models …

The Effect Of Advertising-Focused, Short-Term Study Abroad Programs On Students’ Worldviews, Frauke Hachtmann

College of Journalism and Mass Communications: Faculty Publications

Global employers in the advertising industry are increasingly interested in hiring students with intercultural communication skills and cultural experience. While the benefits of long-term study abroad programs are well documented, this study focuses on advertising-specific, short-term study abroad programs. The purpose was to explore the effectiveness of such programs on students’ worldviews using a mixed methods design. The results show that students displayed lower levels of ethnocentrism after participating in short-term, advertising-focused study abroad programs. In addition, five qualitative themes emerged: an awareness of and appreciation for the out-group, an increased awareness of the in-group, the importance of communication, a …

Lymph Node Ratio Is An Important And Independent Prognostic Factor For Patients With Stage Iii Melanoma, Adam C. Berger, Michael Fierro, John C. Kairys, David Berd, Takami Sato, Jocelyn Andrel, Terry Hyslop, Michael J. Mastrangelo

Kimmel Cancer Center Faculty Papers

INTRODUCTION:

The incidence of melanoma is dramatically increasing worldwide. We hypothesized that the ratio of metastatic to examined lymph node ratio (LNR) would be the most important prognostic factor for stage III patients.

METHODS:

We retrospectively reviewed our institutional database of melanoma patients and identified 168 patients who underwent lymph node dissection (LND) for stage III disease between 1993 and 2007. Patients were divided into three groups based on LNR (≤10%, n = 93; 10-≤25%, n = 45; and >25%, n = 30). Univariate and multivariate analysis was performed using Cox proportional hazards model.

RESULTS:

The median survival time of …

Bats Of Barbados, Hugh H. Genoways, Roxanne J. Larsen, Scott C. Pedersen, Gary G. Kwiecinski, Peter A. Larsen

University of Nebraska State Museum: Mammalogy Papers

The chiropteran fauna of Barbados includes representatives of four families — Noctilionidae, Phyllostomidae, Vespertilionidae, and Molossidae — including 1 piscivore (Noctilio leporinus), 1 omnivore (Brachyphylla cavernarum), 1 pollenivore/nectarivore (Monophyllus plethodon), 1 frugivore (Artibeus jamaicensis), and 2 insectivorous species (Myotis nyctor and Molossus molossus). Despite an early report, we believe that preponderance of the evidence available at this time is that E. fuscus is not part of the fauna of Barbados. The Barbadian chiropteran fauna of 6 species is much smaller than those on the four neighboring Lesser Antillean islands to …
