Limited Role Of Functional Differentiation In Early Diversification Of Animals, Matthew L. Knope, N A. Heim, L O. Frishkoff, J L. Payne
Limited Role Of Functional Differentiation In Early Diversification Of Animals, Matthew L. Knope, N A. Heim, L O. Frishkoff, J L. Payne
Biology Faculty Publications
The origin of most animal phyla and classes during the Cambrian explosion has been hypothesized to represent an ‘early burst’ of evolutionary exploration of functional ecological possibilities. However, the ecological history of marine animals has yet to be fully quantified, preventing an assessment of the early-burst model for functional ecology. Here we use ecological assignments for 18,621 marine animal genera to assess the relative timing of functional differentiation versus taxonomic diversification from the Cambrian to the present day. We find that functional diversity increased more slowly than would be expected given the history of taxonomic diversity. Contrary to previous inferences …
Changes In Plant Species Composition And Structure In Two Peri-Urban Nature Preserves Over 10 Years, Rebecca W. Dolan, Jessica D. Stepens, Marcia E. Moore
Changes In Plant Species Composition And Structure In Two Peri-Urban Nature Preserves Over 10 Years, Rebecca W. Dolan, Jessica D. Stepens, Marcia E. Moore
Scholarship and Professional Work - LAS
Peri-urban natural areas, at the boundaries of cities and adjacent agricultural/rural land, are subject to ecological threats endemic to both land use types. We used permanent plots to document changes in habitat quality by monitoring herbaceous-layer plant species presence and cover over a decade (1996/97 and 2007) in two peri-urban nature preserves in central Indiana, U.S.A. The preserves are comprised of different forest community types: wet-mesic depressional forest and mesic upland forest. Habitat characteristics, based on Floristic Quality Assessment parameters, showed only a single change for either preserve between survey years: wetness values were lower in the wet-mesic depressional site …
Temporal Comparisons On The Genetic Variation Of The Dusky Gopher Frog (Lithobates Sevosus), Kristin Michelle Hinkson
Temporal Comparisons On The Genetic Variation Of The Dusky Gopher Frog (Lithobates Sevosus), Kristin Michelle Hinkson
Online Theses and Dissertations
Monitoring temporal changes in genetic diversity within populations can provide vital information on future viability. The dusky gopher frog, Lithobates sevosus, exists in isolation with an estimated population size of 100-200 individuals, and previous research has shown that low genetic variability exists as a consequence of isolation and population size reduction. However, the temporal changes in genetic variation are not known. Therefore, my objectives were to (1) determine temporal trends in population genetic variation and implications for long-term viability of L. sevosus and (2) estimate effective population size. To accomplish these objectives, egg samples collected from 1997 to 2014 were …
An Evolutionary Perspective On Human Cross-Sensitivity To Tree Nut And Seed Allergens, Amanda E. Fisher, Annalise M. Nawrocki
An Evolutionary Perspective On Human Cross-Sensitivity To Tree Nut And Seed Allergens, Amanda E. Fisher, Annalise M. Nawrocki
Aliso: A Journal of Systematic and Floristic Botany
Tree nut allergies are some of the most common and serious allergies in the United States. Patients who are sensitive to nuts or to seeds commonly called nuts are advised to avoid consuming a variety of different species, even though these may be distantly related in terms of their evolutionary history. This is because studies in the literature report that patients often display sensitivity to multiple nut species (cross-sensitivity) if they have an existing nut allergy. These reports suggest that cross-sensitivity in patients with nut allergies may be caused by an IgE antibody reacting with epitopes present in the seed …
Rarity In Astragalus: A California Perspective, Philip W. Rundel, Thomas R. Huggins, Barry A. Prigge, M. Rasoul Sharifi
Rarity In Astragalus: A California Perspective, Philip W. Rundel, Thomas R. Huggins, Barry A. Prigge, M. Rasoul Sharifi
Aliso: A Journal of Systematic and Floristic Botany
Astragalus (Fabaceae), the largest genus of plants in the world with an estimated 3270 species, is known for large numbers of rare endemic species. An inventory of patterns of climatic, topographic, and edaphic diversity of Astragalus taxa in California (98 native species and 144 named taxa) provides a means to understand the occurrence of rarity in relation to climatic equitability and regional species richness of congeneric taxa. Most taxa in the genus have relatively small ranges of distribution, with 50% restricted geographically to a single Jepson Bioregion. The California Native Plant Society lists 51 Astragalus taxa (35% of the native …

Role Of Low Exposure To Metals As Male Reproductive Toxicants, H. Anna Jeng, Yeou-Lih Huang, Chih-Hong Pan, Norou Diawara
Community & Environmental Health Faculty Publications
The objective of the study was to examine the associations between environmentally relevant low metal concentrations and semen quality parameters in men. The concentrations of zinc (Zn), copper (Cu), cadmium (Cd), arsenic (As), selenium (Se), and lead (Pb) in the seminal plasma and urine were measured from 196 male human subjects in Taiwan. Urinary Cd concentrations were negatively associated with sperm viability (p=0.006). Seminal plasma Cu concentrations of the normal group (>= 15 x 10(6)/ml) were significantly lower than those of the abnormal group (p=0.023). However, the linear regression analysis showed a weak association between Cu concentration and sperm …
The Role Of Cognition In Sexual Signals And Mate Choice Decisions, Ross Minter
The Role Of Cognition In Sexual Signals And Mate Choice Decisions, Ross Minter
Electronic Theses and Dissertations
Cognitive ability varies dramatically among individuals, yet the manner in which this variation affects reproduction has rarely been investigated. Here, we asked 1) whether male sexual signals reflect cognitive ability and whether females prefer males with superior cognitive abilities, and 2) whether female cognition affects male and female mating decisions? We addressed these questions in a mutual mate choice system, threespine sticklebacks (Gasterosteus aculeatus). We tested cognitive performance by presenting the males and females with a novel task (a barrier to food) to evaluate problem-solving abilities and learning. We found that males that problem solve have elaborate sexual …
The Impacts Of Climate Change Mitigation Strategies On Animal Welfare, Sara Shields, Geoffrey Orme-Evans
The Impacts Of Climate Change Mitigation Strategies On Animal Welfare, Sara Shields, Geoffrey Orme-Evans
Animal Welfare Collection
The objective of this review is to point out that the global dialog on reducing greenhouse gas emissions in animal agriculture has, thus far, not adequately considered animal welfare in proposed climate change mitigation strategies. Many suggested approaches for reducing emissions, most of which could generally be described as calls for the intensification of production, can have substantial effects on the animals. Given the growing world-wide awareness and concern for animal welfare, many of these approaches are not socially sustainable. This review identifies the main emission abatement strategies in the climate change literature that would negatively affect animal welfare and …
The Sensitivity Of Qba Assessments Of Sheep Behavioural Expression To Variations In Visual Or Verbal Information Provided To Observers, P. A. Fleming, S. L. Wickham, C. A. Stockman, E. Verbeek, L. Matthews, F. Wemelsfelder
The Sensitivity Of Qba Assessments Of Sheep Behavioural Expression To Variations In Visual Or Verbal Information Provided To Observers, P. A. Fleming, S. L. Wickham, C. A. Stockman, E. Verbeek, L. Matthews, F. Wemelsfelder
Sentience Collection
Qualitative behavioural assessment (QBA) is based on observers’ ability to capture the dynamic complexity of an animal’s demeanour as it interacts with the environment, in terms such as tense, anxious or relaxed. Sensitivity to context is part of QBA’s integrative capacity and discriminatory power; however, when not properly managed it can also be a source of undesirable variability and bias. This study investigated the sensitivity of QBA to variations in the visual or verbal information provided to observers, using free-choice profiling (FCP) methodology. FCP allows observers to generate their own descriptive terms for animal demeanour, against which each animal’s expressions …
The Use Of Judgement Bias To Assess Welfare In Farm Livestock, L. Baciadonna, A. G. Mcelligott
The Use Of Judgement Bias To Assess Welfare In Farm Livestock, L. Baciadonna, A. G. Mcelligott
Sentience Collection
The development of accurate measures of animal emotions is important for improving and promoting animal welfare. Cognitive bias indicates the effect of emotional states on cognitive processes, such as memory, attention, and judgement. Cognitive bias tests complement existing behavioural and physiological measures for assessing the valence of animal emotions indirectly. The judgement bias test has been used to assess emotional states in non-human animals; mainly in laboratory settings. The aim of this review is to summarise the findings on the use of the judgement bias test approach in assessing emotions in non-human animals, focusing in particular on farm livestock. The …
Compassion As A Practical And Evolved Ethic For Conservation, David Ramp, Marc Bekoff
Compassion As A Practical And Evolved Ethic For Conservation, David Ramp, Marc Bekoff
Conservation Collection
The ethical position underpinning decisionmaking is an important concern for conservation biologists when setting priorities for interventions. The recent debate on how best to protect nature has centered on contrasting intrinsic and aesthetic values against utilitarian and economic values, driven by an inevitable global rise in conservation conflicts. These discussions have primarily been targeted at species and ecosystems for success, without explicitly expressing concern for the intrinsic value and welfare of individual animals. In part, this is because animal welfare has historically been thought of as an impediment to conservation. However, practical implementations of conservation that provide good welfare outcomes …

Maintaining Ethical Standards During Conservation Crises, Ryan K. Brook, Mark Cattet, Chris T. Darimont, Paul C. Paquet, Gilbert Proulx
Ethics and Conservation Biology Collection
Many species at risk in Canada and globally are at or approaching a crisis, especially where little or nothing consequential is being done to prevent extirpation. Such is the case of endangered boreal caribou (Rangifer tarandus caribou) in southern Alberta, Canada. Expedient but inadequate emergency ‘fixes’ have been experimentally implemented to arrest their decline and potential extirpation, but use of these measures raises important ethical problems. In their study of the effects of killing wolves (Canis lupus) on the Little Smoky woodland caribou population, Hervieux et al. (2014a) employed lethal methods that included shooting a firearm from a helicopter and …
Updated Marine Mammal Distribution And Abundance Estimates In British Columbia, Benjamin D. Best, Caroline H. Fox, Rob Williams, Patrick H. Halpin, Paul C. Paquet
Updated Marine Mammal Distribution And Abundance Estimates In British Columbia, Benjamin D. Best, Caroline H. Fox, Rob Williams, Patrick H. Halpin, Paul C. Paquet
Population Distribution and Habitat Collection
Information relating to the distribution and abundance of species is critical for effective conservation and management. For many species, including cetacean species of conservation concern, abundance estimates are lacking, out of date and/or highly uncertain. Systematic, line-transect marine mammal surveys were conducted in British Columbia’s (BC) coastal waters over multiple years and seasons (summer 2004, 2005, 2008, and spring/autumn 2007). In total, 10,057km of transects were surveyed in an 83,547km2 study area. Abundance estimates were calculated using two different methods: Conventional Distance Sampling (CDS) and Density Surface Modelling (DSM). CDS generates a single density estimate for each stratum, whereas DSM …

Biology and Environmental Science Faculty Publications
Morgellons disease (MD) is a complex skin disorder characterized by ulcerating lesions that have protruding or embedded filaments. Many clinicians refer to this condition as delusional parasitosis or delusional infestation and consider the filaments to be introduced textile fibers. In contrast, recent studies indicate that MD is a true somatic illness associated with tickborne infection, that the filaments are keratin and collagen in composition and that they result from proliferation and activation of keratinocytes and fibroblasts in the skin. Previously, spirochetes have been detected in the dermatological specimens from four MD patients, thus providing evidence of an infectious process. Methods …

Behavioral Observations: Foraging And Aggression Of Neotropical Migrants And Resident Birds In Panama, Jessica M. Johnston, Samuel B. King, Ryan A. Levering
Rice Rivers Center Research Symposium
Lyons suggests that foraging data in songbirds can be an indicator of food abundance, with higher attack rate= higher habitat quality; higher foraging speed= lower habitat quality (2005). Territorial behavior such as interspecific aggression among songbirds may also be related to food availability. Previous studies have documented variation in the extent of territorial and aggressive behaviors among resident and Neotropical migratory species on tropical wintering grounds. This research gathered foraging and aggression data at two coastal angroves sites in central Panama, one on the Caribbean Coast (Galeta) and one on the Pacific Coast (Juan Diaz-East). Foraging data was used an …
Phytoremediation Of Metal Contamination Using Salix (Willows), Gordon J. Kersten
Phytoremediation Of Metal Contamination Using Salix (Willows), Gordon J. Kersten
Electronic Theses and Dissertations
Abandoned hardrock mines and the resulting Acid Mine Drainage (AMD) are a source of vast, environmental degradation that are toxic threats to plants, animals, and humans. Cadmium (Cd) and lead (Pb) are metal contaminants often found in AMD. In my mine outwash water samples, cadmium and lead concentrations were 19 and 160 times greater than concentrations in control waterways, and 300 and 40 times greater than EPA Aquatic Life Use water quality standards, respectively. I tested the phytoremediation characteristics of three montane willows native to the Rocky Mountains: Salix drummondiana, S. monticola, and S. planifolia. I tested …
Traditional Medicine Usage And The Transmission Of Traditional Ecological Knowledge In Three Villages Near Phnom Kulen National Park, Kayla N. Deur
Traditional Medicine Usage And The Transmission Of Traditional Ecological Knowledge In Three Villages Near Phnom Kulen National Park, Kayla N. Deur
Environmental Studies / Environmental Science Student Scholarship
Traditional ecological knowledge refers to knowledge regarding the relationships between humans and the natural environment. This knowledge and skill set is acquired by local and indigenous peoples through generations of direct contact with the environment, and is often shared in an intergenerational pattern of verbal retelling and instruction. Traditional medicine is one component of traditional ecological knowledge, and this paper outlines the investigation of traditional medicine usage and the transmission of such knowledge in three villages near Phnom Kulen National Park in Siem Reap, Cambodia. The study was conducted through semi-structured interviews at homes that were both randomly and purposively …
Morphology And Niche Partitioning Of Fish Assemblage In The Tonle Sap Biosphere Reserve - A Case Study Of The Prek Toal Core Area, Lan Thi Ngoc Nguyen
Morphology And Niche Partitioning Of Fish Assemblage In The Tonle Sap Biosphere Reserve - A Case Study Of The Prek Toal Core Area, Lan Thi Ngoc Nguyen
Environmental Studies / Environmental Science Student Scholarship
A morphological approach provides vital information on community structure and ecological adjustments among different species that occupy in the same habitat. The coexistence of competing species in a diverse community results in niche partitioning in order to increase stabilization. Tonle Sap Biosphere Reserve, one of the world’s most productive inland wetlands is a tropical river ecosystem so dynamic that supports high biodiversity, especially fish population. This study tests the relationship between morphology and niche partitioning to understand the coexistence of diverse fish assemblages in the Tonle Sap Biosphere Reserve. By measuring 31 morphological variables and gathering ecological data of the …

Corn Residue Stocking Rate Affects Cattle Performance But Not Subsequent Grain Yield, L. A. Stalker, Humberto Blanco-Canqui, Jennifer A. Gigax, A. L. Mcgee, T. M. Shaver, S. J. Van Donk
West Central Research and Extension Center, North Platte
This study investigated effects of stocking rate on cattle performance, quality and quantity of corn residue, and impact of residue removal on grain yield for 5 yr at the University of Nebraska – Lincoln West Central Water Resources Field Laboratory near Brule, NE. Four removal treatments—1) no removal (control), 2) grazing at 2.5 animal unit month (AUM)/ ha, 3) grazing at 5.0 AUM/ha, and 4) baling—were applied to a center pivot–irrigated corn field (53 ha). The field was divided into eight 6.6-ha paddocks to which replicated treatments were assigned. Samples of residue were collected in October and March (before and …
Abiotic Habitat Preferences Of Age-0 Paddlefish In Lake Sakakawea, North Dakota During Late Summer, Derek Dufault
Abiotic Habitat Preferences Of Age-0 Paddlefish In Lake Sakakawea, North Dakota During Late Summer, Derek Dufault
Journal of Earth and Life Science
Since the early 1990’s, surface visual counts along transects have been conducted annually, allowing for estimates of relative abundance and year-class strength of age-0 paddlefish Polyodon spathula on the upper portions of Lake Sakakawea, North Dakota. This study focuses on the annual visual surface count data collected over an eleven year period from 2004-2014. More specifically it focuses on abiotic habitat factors (Secchi depth, water depth, and water temperature) and how they relate to age-0 paddlefish locations in late summer. Understanding habitat use during early life stages is imperative, yet to date, there is very limited knowledge available regarding the …
Influence Of Depth And Retrieval Speed On Yellow Perch Barotrauma Recovery Time In Winter, Bradley J. Klingsheim
Influence Of Depth And Retrieval Speed On Yellow Perch Barotrauma Recovery Time In Winter, Bradley J. Klingsheim
Journal of Earth and Life Science
Physoclistous fish are often affected by barotrauma because the swim bladder is not connected to the esophagus. Barotrauma is increasingly being used in assessing mortality in fish brought from deep water. Barotrauma is the physical damage that occurs because of the over inflation of the gas bladder resulting from a rapid decrease in ambient pressure. The two important factors influencing barotrauma effects are water depth and decompression. In this study, two experiments were conducted on yellow perch (Perca flavescens) at three depth locations on Grace Lake, Bemidji, Minnesota. Fish were measured for barotrauma recovery time (s) following capture by hook …
Further Description Of Hybridization In The Sea Stars Asterias Rubens And Asterias Forbesi Through The Application Of Species-Specific Genetic Markers, Callie Bateson
Honors Program Theses
Hybridization occurs when two separate species reproduce to form hybrid offspring. If the hybrid offspring backcross with individuals of their parental species, the subsequent offspring may have varying amounts of the parental genomes, if viable. Following the retreat of the Last Glacial Maxima 20,000 years ago, two sea star species, Asterias forbesi and A. rubens came into secondary contact in the Gulf of Maine where they began to hybridize. Previous research in our lab studied the frequency of hybridization at four locations along the east coast (Quebec, Nova Scotia, New Hampshire, and New York) using morphological identifications as well two …

Papers in Ecology
Benthic infaunal communities are important components of coastal ecosystems. Understanding the relationships between the structure of these communities and characteristics of the habitat in which they live is becoming progressively more important as coastal systems face increasing stress from anthropogenic impacts and changes in climate. To examine how sediment characteristics and infaunal community composition were related along the northern Gulf of Mexico coast, we sampled intertidal infaunal communities at seven sites covering common habitat types at a regional scale. Across 69 samples, the communities clustered into four distinct groups on the basis of faunal composition. Nearly 70% of the variation …
Comparative Proteomics Of Mouse Tears And Saliva: Evidence From Large Protein Families For Functional Adaptation, Robert C. Karn, Christina M. Laukaitis
Comparative Proteomics Of Mouse Tears And Saliva: Evidence From Large Protein Families For Functional Adaptation, Robert C. Karn, Christina M. Laukaitis
Scholarship and Professional Work - LAS
We produced a tear proteome of the genome mouse, C57BL/6, that contained 139 different protein identifications: 110 from a two-dimensional (2D) gel with subsequent trypsin digestion, 19 from a one-dimensional (1D) gel with subsequent trypsin digestion and ten from a 1D gel with subsequent Asp-N digestion. We compared this tear proteome with a C57BL/6 mouse saliva proteome produced previously. Sixteen of the 139 tear proteins are shared between the two proteomes, including six proteins that combat microbial growth. Among the 123 other tear proteins, were members of four large protein families that have no counterparts in humans: Androgen-binding proteins (ABPs) …

Coral islands around the world are threatened by changing climates. Rising seas, drought, and increased tropical storms are already impacting island ecosystems. We aim to better understand lichen community ecology of coral island forests. We used an epiphytic lichen community survey to gauge Pisonia (Pisonia grandis R.BR.), which dominates forest conditions on Heron Island, Australia. Nine survey plots were sampled for lichen species presence and abundance, all tree diameters and species, GPS location, distance to forest-beach edge, and dominant forest type. Results found only six unique lichens and two lichen associates. A Multi-Response Permutation Procedures (MRPP) test found statistically distinct …

The Enigmatic Milliped Genus Pandirodesmus Silvestri 1932 And Description Of A New Species From Tobago Represented By Males (Polydesmida: Leptodesmidea: Chelodesmidae: Chelodesminae: Pandirodesmini), Rowland M. Shelley, Jamie M. Smith
Insecta Mundi
Pandirodesmus rutherfordi, n. sp., represented by 18 individuals including eight adult males, occurs in secondary forests near Charlotteville and Speyside, Tobago, Trinidad and Tobago. Along with the type and second species, P. disparipes Silvestri, from Guyana and known only from females, the segmental legs of P. rutherfordi alternate between long (anterior pairs) and short (posterior ones), spiracular openings are on straw-like tubules, and ozopores are located on paramedian metatergal spines. These features appear to be adaptations for biotopes of loose sand, detritus, or frass, and 17 specimens, including the six juveniles, exhibit coatings of “sand grains” that are loosely …

The Trichoptera Of Panama I. New Records For Caddisflies (Insecta: Trichoptera) From The Republic Of Panama, Brian J. Armitage, Steven C. Harris, Ralph W. Holzenthal
Insecta Mundi
The Republic of Panama currently has 245 recorded species of Trichoptera distributed among 13 families. Herein we add 32 new country records for Panama, including one new family (Limnephilidae) and one new genus (Limnephilus). We also provide the first collection information for Oxyethira maya Denning for Panama. These results are part of an ongoing effort to characterize the caddisfly fauna of Panama, and to evaluate that country’s major cuencas (water basins).
