Coexistence And The Niche In A Nurse-Cactus Interaction: Is Cyclic Dynamics Justified?, Arnoldo Flores-Torres, Carlos Montaña, Miguel Franco

School of Biological and Marine Sciences

1. The interaction between the nurse plant Larrea tridentata and the cacti Cylindropuntia leptocaulis is thought to follow cyclical-replacement dynamics. However, the required changing nature of their interaction, from facilitation to competition, has not been investigated through their full life cycle. 2. In order to test the hypothesised cyclical dynamics, we compared the demography of four sub-populations (LA = Larrea associated to Cylindropuntia; CA = Cylindropuntia associated to Larrea, LS = solitary Larrea; CS = solitary Cylindropuntia) in the Mapimí Biosphere Reserve, Mexico, over the period 2008-2015. This allowed us to compare their demography at varying levels of the generally …

Postglacial Colonization Of Northern Coastal Habitat By Bottlenose Dolphins: A Marine Leading-Edge Expansion?, Milaja Nykänen, Kristin Kaschner, Willy Dabin, Andrew Brownlow, Nicholas J. Davison, Rob Deaville, Cristina Garilao, Kathleen Kesner-Reyes, M. Thomas P. Gilbert, Rod Penrose, Valentina Islas-Villanueva, Nathan Wales, Simon N. Ingram, Emer Rogan, Marie Louis, Andrew D. Foote

School of Biological and Marine Sciences

Oscillations in the Earth’s temperature and the subsequent retreating and advancing of ice-sheets around the polar regions are thought to have played an important role in shaping the distribution and genetic structuring of contemporary high-latitude populations. After the Last Glacial Maximum (LGM), retreating of the ice-sheets would have enabled early colonizers to rapidly occupy suitable niches to the exclusion of other conspecifics, thereby reducing genetic diversity at the leading-edge. Bottlenose dolphins (genus Tursiops) form distinct coastal and pelagic ecotypes, with finer-scale genetic structuring observed within each ecotype. We reconstruct the postglacial colonization of the Northeast Atlantic (NEA) by bottlenose dolphins …

Plastics, The Environment And Society: Current Consensus And Future Directions, Richard C. Thompson, Sabine Pahl

School of Biological and Marine Sciences

In less than 60 years, plastics have transformed our daily lives. Usage is increasing and now exceeds 330 million tonnes per annum. In this concluding chapter we summarise current understanding about the benefits and concerns of plastics usage and look to future priorities, challenges and opportunities. It is clear that plastics bring many societal benefits and offer the potential for further advances in medical and technological applications, as well as carbon reductions. However, it is also widely acknowledged that current production, use and disposal of plastics is not sustainable. Our understanding of the issues associated with end of life plastics …

Impacts Of The Mycotoxin Zearalenone On Growth And Photosynthetic Responses In Laboratory Populations Of Freshwater Macrophytes (Lemna Minor) And Microalgae (Pseudokirchneriella Subcapitata)., Ej Eagles, R Benstead, S Macdonald, R Handy, Th Hutchinson

School of Biological and Marine Sciences

Mycotoxins are an important class of chemicals of emerging concern, recently detected in aquatic environments, potentially reflecting the influence of fungicide resistance and climatic factors on fungal diseases in agricultural crops. Zearalenone (ZON) is a mycotoxin formed by Fusarium spp. and is known for its biological activity in animal tissues; both in vitro and in vivo. ZON has been reported in US and Polish surface waters at 0.7 - 96 ng/L, with agricultural run-off and wastewater treatment plants being the likely sources of mycotoxins. As some mycotoxins can induce phytotoxicity, laboratory studies were conducted to evaluate the toxicity of ZON …

Bioavailability And Effects Of Microplastics On Marine Zooplankton: A Review., Zara L.R. Botterell, Nicola Beaumont, Tarquin Dorrington, Michael Steinke, Richard C. Thompson, Penelope K. Lindeque

School of Biological and Marine Sciences

Microplastics are abundant and widespread in the marine environment. They are a contaminant of global environmental and economic concern. Due to their small size a wide range of marine species, including zooplankton can ingest them. Research has shown that microplastics are readily ingested by several zooplankton taxa, with associated negative impacts on biological processes. Zooplankton is a crucial food source for many secondary consumers, consequently this represents a route whereby microplastic could enter the food web and transfer up the trophic levels. In this review we aim to: 1) evaluate the current knowledge base regarding microplastic ingestion by zooplankton in …

Patchiness In Habitat Distribution Can Enhance Biological Diversity Of Coastal Engineering Structures, Eva Cacabelos, Richard C. Thompson, Afonso C.L. Prestes, José Manuel N. Azevedo, Ana I. Neto, Gustavo M. Martins

School of Biological and Marine Sciences

© 2018 John Wiley & Sons, Ltd. Urbanization of coastal habitats is increasing worldwide. However, most man-made structures are poor surrogates for the habitats they replace and can strongly impact the diversity and functioning of coastal habitats. The value of coastal engineering can be enhanced by the provision of microhabitats that facilitate colonization by marine life. One step forward is moved in this research by combining species coexistence theory, resource patchiness and applied ecology in order to find ways that maximize the biological diversity of coastal defence structures. Featureless areas of a seawall were modified by the addition of microhabitats …

Soft-Surface Grasping: Radular Opening In Aplysia Californica, Catherine E. Kehl, Joey Wu, Sisi Lu, Richard F. Drushel, Rebekah K. Smoldt, Hillel J. Chiel

Faculty Scholarship

Grasping soft, irregular material is challenging both for animals and robots. The feeding systems of many animals have adapted to this challenge. In particular, the feeding system of the marine mollusk Aplysia californica, a generalist herbivore, allows it to grasp and ingest seaweeds of varying shape, texture and toughness. On the surface of the grasper of A. californica is a structure known as the radula, a thin flexible cartilaginous sheet with fine teeth. Previous in vitro studies suggested that intrinsic muscles, I7, are responsible for opening the radula. Lesioning I7 in vivo does not prevent animals from grasping and ingesting …

Systematic Control Of Aged Skeletal Muscle Following High-Intensity Stretch-Shortening Contraction Exercise Training: Epigenomic Regulation And Signaling Factors Underpinning Adaptation, Marshall Alan Naimo Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

Sarcopenia, the age-related decline in skeletal muscle mass, results in a loss of strength and functional capacity, which subsequently increases the risk of disease, disability, frailty, and all-cause mortality. Exercise is known to be an efficacious paradigm for improving health and attenuating or preventing many chronic diseases. For the previous two decades, our laboratory has established an in vivo rodent dynamometer model to explore the effects of various skeletal muscle training paradigms following stretch-shortening contractions (SSCs).The responses tohigh-intensity resistance-type exercise training (RTET) using this physiological model ranges from adaptation, characterized by enhanced skeletal muscle performance along with increased muscle mass, …

Glial Cell Expansion And Intercellular Signaling In The Developing Medial Nucleus Of The Trapezoid Body (Mntb), Ashley N. Brandebura

Graduate Theses, Dissertations, and Problem Reports (ETD)

Neural circuit formation is a complex process involving coordinated communication between neurons, glia and vascular-associated cells (VACs). Each cell type is responsible for a unique transcriptional and translational contribution to tissue maturation. Deciphering the intercellular signaling patterns which guide neural circuit formation during normal development is thus an essential step in understanding which components of neural circuit formation go awry in neurodevelopmental disorders. The medial nucleus of the trapezoid body (MNTB), located in the auditory brainstem, was used as a model system to study the dynamics of neural circuit formation because it contains a mostly homogeneous population of postsynaptic neurons …

Behavioral Responses Of Individual Blue Whales (Balaenoptera Musculus) To Mid-Frequency Military Sonar, Brandon L. Southall, Stacy L. Deruiter, Ari Friedlaender, Alison K. Stimpert

University Faculty Publications and Creative Works

This study measured the degree of behavioral responses in blue whales (Balaenoptera musculus) to controlled noise exposure off the southern California coast. High-resolution movement and passive acoustic data were obtained from non-invasive archival tags (n=42) whereas surface positions were obtained with visual focal follows. Controlled exposure experiments (CEEs) were used to obtain direct behavioral measurements before, during and after simulated and operational military mid-frequency active sonar (MFAS), pseudorandom noise (PRN) and controls (no noise exposure). For a subset of deep-feeding animals (n=21), active acoustic measurements of prey were obtained and used as contextual covariates in response analyses. To investigate potential …

Cultivating Acute Care Rehabilitation Team Collaboration Using The Kawa Model, Jayme L. Ober, Jennifer E. Lape

Internet Journal of Allied Health Sciences and Practice

Purpose: Effective healthcare team collaboration is imperative for quality client-centered care, job satisfaction, and overall morale. Rehabilitation team collaboration can be impacted by high productivity demands, differing backgrounds of individual team members, and the unpredictable healthcare environment. The Kawa (river) model, a culturally-neutral model of occupational therapy practice, has been shown to improve communication and collaboration with its use of metaphors, but its utility in various contexts to enhance collaborative practice is still being explored. The purpose of this study was to implement an evidence-based teambuilding intervention with use of the Kawa model to investigate the impact on acute care …

An Assessment Of Emotional-Force And Cultural Sensitivity The Usage Of English Swearwords By L1 German Speakers, Sarah Dawn Cooper

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examines the usage of English swearwords by L1 German speakers and poses the following three questions: (1) Which English swearwords do native-speakers of German use? (2) In which situations do German speakers use English swearwords? Why do they use English swearwords instead of their German counterparts? (3) What emotional weight do they apply to swearwords in English (i.e. How taboo are they)? In an effort to understand Germans’ use of swearwords today, potential attributing factors were assessed and evaluated in a 15-question survey comprised of both qualitative and quantitative components that was taken by 403 participants from Germany …

Sight-Seeing In School: Visual Technology, Virtual Experience, And World Citizenship In American Education, 1900-1930, Katie Day Good

University Faculty Publications and Creative Works

This article argues that the influx of media technologies into schools between 1900 and 1930 was facilitated by an emergent techno-utopian rhetoric in American culture that placed new social value on the acquisition of virtual and worldly experience. Against a backdrop of rising immigration, global visual culture, and American intervention in foreign affairs, the burgeoning educational technology industry-including producers of stereographs, slides, and National Geographic magazine-made inroads into schools by endowing technology with the capacity to "bring the world to the pupil" and serve as a substitute for travel. Aligning with progressive reformers, boosters of early educational technology highlighted these …

Effects Of A Tactile Safeness Intervention On Experiences Of Shame And Compassion, Jamie L. Baum

EWU Masters Thesis Collection

Previous research has shown that tactile attachment interventions are able to mitigate experiences of social threat and facilitate compassionate and altruistic responding. Building off of those findings, this study examines the effects of touching an inanimate object - a teddy bear- upon experiences of shame, compassion, and different emotions after the induction of a shame memory. Eighty-one participants recruited from Eastern Washington University participated in this study. Participants were randomly assigned to one of two conditions, in which they held either a teddy bear or water bottle. Participants were then prompted to think of a time they have experienced shame …

High Resolution Modeling Of Tick Density And Detection Of Rickettsia Spp. In Dermacentor Spp. Ticks At Turnbull National Wildlife Refuge, Wa, Justin L. Donahue

EWU Masters Thesis Collection

The tick species Dermacentor andersoni and Dermacentor variabilis are known vectors of pathogens. One such pathogen is the bacteria Rickettsia rickettsii, which causes Rocky Mountain spotted fever. The detection of this bacterium in ticks at Turnbull National Wildlife Refuge (TNWR) indicates a potential risk to human health. In order to follow up on this discovery, we had two separate objectives. First we developed a high resolution predictive map for Dermacentor spp. distribution across the public use area of TNWR. To do so, 50m transects (27 in total) were established across the public use area. Ticks were collected weekly within the …

Home Range, Habitat Use And Thermal Ecology Of The Florida Box Turtle (Terrapene Bauri) On An Anthropogenic Island In Southwestern Florida, Christina Demetrio

Antioch University Dissertations & Theses

Limited information is available on the ecology of Terrapene bauri (Florida Box Turtle) in mangrove ecosystems. Radio-telemetry and iButton data loggers were used to study the home range, habitat use, and thermal ecology of ten Florida Box Turtles on an anthropogenic island in the mangrove-dominated region of southwestern Florida. The effects of weather variables on movement and activity were also examined. Home range analysis using Minimum Convex Polygons (MCP) and Kernel Density Estimates (KDE) determined an average home range size of 0.81 ha (MCP) and 2.32 ha (95% KDE). Box Turtles moved an average distance of 6.3 m per day …
