The Potential Impacts Of Climate Change On Avitourism To Islands: The Example Of Fair Isle, Scotland, Richard W. Butler Professor
The Potential Impacts Of Climate Change On Avitourism To Islands: The Example Of Fair Isle, Scotland, Richard W. Butler Professor
International Journal of Islands Research
This paper discusses the potential impact of climate change upon a specific form of tourism, avitourism (birdwatching), and the resulting effects upon islands dependent upon this form of tourism. Bird populations, distributions and migratory patterns are all vulnerable to the impacts of global warming, extreme weather events and changes in the marine environment, as are the islands which provide their habitat. Avitourism is a lucrative and non-consumptive form of tourism that is of major importance to some small islands, particularly those that have unique indigenous breeding species and/or are visited by migrating species on a regular basis. A number of …

Temperature Stress On Physiological And Morphological Traits In Rhizophora Apiculata, Baseem M. Tamimi, Wan Juliana W. A., Nizam M. S., Che Radziah Che Mohd. Zain
Baghdad Science Journal
Global warming has had considerable effects on vital ecosystems, which has also been caused by increased temperatures and CO2 that follow changes in different abiotic factors, which poses threats to mangrove forests environment. This research was conducted to examine the physiological and morphological characteristics of the Rhizophora apiculata mangrove regarding higher air temperature for the variety of tree species that respond to climate change. Seedlings were cultivated for three months in regulated growth chambers with three varying temperatures of 38°C, 21°C under CO2 at 450 ppm, and ambient CO2 concentration i.e., 450 ± 20 ppm under average temperature at 28°C …
Inflammatory Mediation Of Heat Stress-Induced Growth Deficits In Livestock And Its Potential Role As A Target For Nutritional Interventions: A Review, Micah S. Most, Dustin T. Yates
Inflammatory Mediation Of Heat Stress-Induced Growth Deficits In Livestock And Its Potential Role As A Target For Nutritional Interventions: A Review, Micah S. Most, Dustin T. Yates
Department of Animal Science: Faculty Publications
Heat stress is detrimental to well-being and growth performance in livestock, and systemic inflammation arising during chronic heat stress contributes to these poor outcomes. Sustained exposure of muscle and other tissues to inflammation can impair the cellular processes that facilitate muscle growth and intramuscular fat deposition, thus reducing carcass quality and yield. Climate change is expected to produce more frequent extreme heat events, increasing the potential impact of heat stress on sustainable livestock production. Feedlot animals are at particularly high risk for heat stress, as confinement limits their ability to seek cooling from the shade, water, or breeze. Economically practical …
Lost At Sea, Anny Oberlink
Lost At Sea, Anny Oberlink
Capstones
At the end of World War I and World War II, in a new era of peace, nations confronted an unprecedented logistical problem: millions of tons of unexploded ordnance—once a wartime boon—had become a peacetime burden. Faced with a mandate to dispose of excess munitions, militaries turned to dumping their stockpiles into the sea. But now a complex and urgent issue is emerging. Increasingly, as industry looks to build offshore—wind power turbines, internet cables, oil pipelines—they are facing a potential peril: millions of tons of unexploded bombs and ammunition that are lying on the ocean floor can explode or leak …

Understanding Coralline Algal Responses To Ocean Acidification: Meta‐Analysis And Synthesis, Ce Cornwall, Ben P. Harvey, Steeve Comeau, Dl Cornwall, Jason Hall‐Spencer, Viviana Peña, Shigeki Wada, Lucia Porzio
School of Biological and Marine Sciences
Ocean acidification (OA) is a major threat to the persistence of biogenic reefs throughout the world's ocean. Coralline algae are comprised of high magnesium calcite and have long been considered one of the most susceptible taxa to the negative impacts of OA. We summarize these impacts and explore the causes of variability in coralline algal responses using a review/qualitative assessment of all relevant literature, meta-analysis, quantitative assessment of critical responses, and a discussion of physiological mechanisms and directions for future research. We find that most coralline algae experienced reduced abundance, calcification rates, recruitment rates, and declines in pH within the …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Grasslands can significantly contribute to climate mitigation. However, recent trends indicate that human activities have switched their net cooling effect to a warming effect due to management intensification and land conversion. This indicates an urgent need for strategies directed to mitigate climate warming while enhancing productivity and efficiency in the use of land and natural (nutrients, water) resources. Here, we examine the potential of four innovative strategies to slow climate change including: 1) Adaptive multi-paddock grazing that consists of mimicking how ancestral herds roamed the Earth; 2) Agrivoltaics that consists of simultaneously producing food and energy from solar panels on …
Understanding How Changes In Precipitation Intensity Will Affect Vegetation In The Western U.S., Cristina Chirvasa
Understanding How Changes In Precipitation Intensity Will Affect Vegetation In The Western U.S., Cristina Chirvasa
Fall Student Research Symposium 2021
Precipitation events are becoming more intense as the atmosphere warms, but it remains unclear how precipitation intensification will affect plant growth in arid and semiarid ecosystems. There is conflicting evidence suggesting that larger precipitation events may either increase or decrease plant growth. Here, we report the growth responses of herbaceous and woody plants to experimental manipulations of precipitation intensity in a cold, semi-arid ecosystem in Utah, USA. In this experiment, precipitation was collected and redeposited as fewer, larger events with total annual precipitation kept constant across treatments. Results from the first two growing seasons revealed that more intense events ‘pushed’ …

Climate Change Impacts On Atmospheric Ammonia And Implications For Human Health, Casey Olson, Connor Snow, Bridger Jorgensen
Fall Student Research Symposium 2021
According to national data Cache Valley has the highest concentrations of atmospheric ammonia in the nation. This study aims to answer the questions of whether climate variables and events such as precipitation, averaged winds, geopotential height, and teleconnections can be used to predict the behavior of pollutants and how human biology is potentially affected. Data from the Utah Climate Center shows that the 3rd yearly quartile has the highest levels of airborne ammonia due to the high levels of fertilizer use and livestock emissions in the farming industry in Cache Valley. After data analysis, there seems to be a connection …

Digitization Of Entomological Collections At Usu, Eastern Using Scan (Symbiota Collections Of Arthropods Network) Data Portal And Seek! Inaturalist App, Alexandra Cartwright
Fall Student Research Symposium 2021
Pollinators, including bees, provide valuable ecosystem services for native plants and agricultural species. Phenology, or the timing of biological events such as flowering of plants, is changing as a result of climate change. The digitization of specimens allows for insights into species distributions, seasonality, and phenology in 60-70-year-old collections. The entomological collection at Utah State University, Eastern houses approximately 3,000 individual specimens and over 100 bees. The oldest specimens date from 1953, many from the 1960s, 70s, & 80s and the majority of specimens are from Carbon and Emery Counties. Digitization of entomological collections can provide: species distributions: Which species …

Camping, Weather, And Disasters: Extending The Construal Level Theory, Christopher Craig, Siyao Ma, Ismail Karabas, Song Feng
Faculty & Staff Research and Creative Activity
Camping is an outdoor accommodation and type of recreation that is susceptible to weather and climate change. Camping—in addition to the relationships camping shares with weather— remains understudied despite the subsectors’ salient economic impact and high participation rate. The observable effects of non-meteorological/climatological (e.g., pandemic) is also a topic that has received limited attention. Accordingly, we introduce the Camping-Weather-Disaster (CWD) framework to examine the concurrent impact of weather and the COVID-19 disaster on post-disaster camping trip plans among leisure travelers in the 48 contiguous United States (n=2,442). Extending the Construal Level Theory, the CWD framework considers traveler construal (i.e., understanding) …

Evaluation Of Heat Tolerant Cauliflower Varieties On California’S Central Coast, Lauren Booke
Master of Science in Environmental Sciences and Management Projects
Heat tolerant trials of vegetable crops will help to improve food security when it becomes affected by rising temperatures due to climate change. By having heat tolerant vegetable crops, we can ensure the well-being of individuals in our society—nutritionally, economically, and socially. California is responsible for 90% of the cauliflower production in the United States. This research aims to determine the overall productivity of three heat tolerant cauliflower varieties (Bishop, Mardi, Flame Star) during the summer months (July- September) on California’s central coast. Stomatal conductance and chlorophyll fluorescence were measured throughout the growing cycle to evaluate plant stress and photosynthetic …
Implications Of Condition Shifts On Shallow Lakes, Alicia Skolte
Implications Of Condition Shifts On Shallow Lakes, Alicia Skolte
Biology Graduate Theses
Shallow lakes have undergone condition shifts throughout time by natural causes, management actions, or a combination of the two. Because shallow lakes are especially vulnerable to shifts towards turbid conditions, management actions on shallow lakes have focused on water level/retainment, biomanipulations, the management/removal of non-native species, and land-use changes. This review compiles a summary on ecosystem shifts including a discussion on the frequency of shifts historically and the importance and causes of those shifts, trophic cascades, and the influence of introduced species in shallow lakes. This review will then examine case-studies of management-linked shifts and explain current shift theory. Next, …

Weather is thought to influence raptor reproduction through effects on prey availability, condition of adults, and survival of nests and young; however, there are few long-term studies of the effects of weather on raptor reproduction. We investigated the effects of weather on Northern Goshawk (Accipiter gentilis; henceforth goshawk) breeding rate, productivity, and fledging date in south-central Idaho and northern Utah, USA. Using data from 42 territories where we found evidence of breeding attempts in ≥1 yr from 2011–2019, we analyzed breeding rates using 315 territory–season combinations, analyzed productivity for 134 breeding attempts, and analyzed fledging date for 118 …

The Role Of Sex: An Analysis Of U.S. Attitudes Toward Climate Change, Chloe Riggs
Graduate Theses and Dissertations
This study analyzes the intersection of sex, environmental risk perception of climate change, and feminism. More specifically, with a sample size of 8,280 respondents from the American National Election Studies (ANES) 2020 Times Series Study, this research examines the relationship between pro-environmental attitudes and sympathy for feminism, controlling for sex, as well as if a measure of sympathy for feminism influences pro-environmental attitudes, controlling for demographic (age, education, race, sex, and income) and political preference (political ideology and party affiliation) variables. Previous literature strongly supports a sex gap in risk perception, a pattern known as the White Male Effect (WME) …
Phenology Dictates The Impact Of Climate Change On Geographic Distributions Of Six Co-Occurring North American Grasshoppers, Nathan P. Lemoine
Phenology Dictates The Impact Of Climate Change On Geographic Distributions Of Six Co-Occurring North American Grasshoppers, Nathan P. Lemoine
Biological Sciences Faculty Research and Publications
Throughout the last century, climate change has altered the geographic distributions of many species. Insects, in particular, vary in their ability to track changing climates, and it is likely that phenology is an important determinant of how well insects can either expand or shift their geographic distributions in response to climate change. Grasshoppers are an ideal group to test the hypothesis that phenology correlates with range expansion, given that co-occurring confamilial, and even congeneric, species can differ in phenology. Here, I tested the hypothesis that early- and late-season species should possess different range expansion potentials, as estimated by habitat suitability …

Coastal Adaptation To Climate Change Through Zonation: A Review Of Coastal Change Management Areas (Ccmas) In England, J. A. Kirby, G. Masselink, S. Essex, T. Poate, T. Scott
School of Biological and Marine Sciences
Climate change and accelerated rates in sea-level rise are expected to increase flooding and erosion on the world's coastlines. Coastal managers and planners face the challenge of helping communities to adapt to the changing coast. Traditionally hard engineering has been used to defend communities on the coast, but as this option becomes unsustainable and financially unviable, coastal managers are increasingly employing planning policy to mitigate the risk posed by coastal change. Zonation of coastal change areas and delineation of erosion extents, such as set-back lines, are used globally to restrict development in the coastal zone. In England there is policy …
Addressing The Role Of Climate Change In Agriculture And Mexico-Us Immigration, Xiaoxin Liang
Addressing The Role Of Climate Change In Agriculture And Mexico-Us Immigration, Xiaoxin Liang
Binghamton University Undergraduate Journal
Among the greatest threats of climate change is the significant impact on mass displacement, particularly as it relates to Mexico-US immigration. Low crop yields from worsening climate conditions have been linked to increased migration of Mexican farmers. With a projected 4.2 million additional migrants in the foreseeable future, it poses a contemporary environmental, social, and political dilemma. This policy brief analyzes several provision proposals to be adopted into the United States-Mexico-Canada Agreement (USMCA), as evaluated under economic cost, equity, environmental impact, and feasibility criteria. My research concludes that the most effective and direct provision proposal is the implementation of adaptive …

Insects And Their Laboulbeniales (Ascomycota, Fungi) Of Lake Eustis And Emeralda Marsh Conservation Area: A Case Study On Urbanization And Diversity, Patricia J. Kaishian
Purdue University Libraries Open Access Publishing Fund
A rapid biodiversity assessment of insects and associated Laboulbeniales fungi was conducted over the course of five nights in August, 2018, at two central Florida lakes: Lake Eustis and the nearby protected and restored National Natural Landmark, Emeralda Marsh Conservation Area (EMCA), which encompasses a portion of Lake Griffin. Lake Eustis was surveyed for Laboulbeniales in 1897 by mycologist Dr. Roland Thaxter but has not since been investigated. Because Lake Eustis has been urbanized, with the lake perimeter almost entirely altered by human development, the site offers a look into Laboulbeniales diversity across a 121-year timeline, before and after human …

Phenotypic plasticity is one mechanism whereby species may cope with stressful environmental changes associated with climate change. Reef building corals present a good model for studying phenotypic plasticity because they have experienced rapid climate-driven declines in recent decades (within a single generation of many corals), often with differential survival among individuals during heat stress. Underlying differences in thermotolerance may be driven by differences in baseline levels of environmental stress, including pollution stress. To examine this possibility, acute heat stress experiments were conducted on Acropora hyacinthus from 10 sites around Tutuila, American Samoa with differing nutrient pollution impact. A threshold-based heat …

Breeding And Feeding Habitat Selection By An Island Endemic Bird May Increase Its Vulnerability To Climate Change, Paul M. Radley, Eddie J. B. Van Etten, David Blake, Robert A. Davis
Research outputs 2014 to 2021
Characterizing patterns of habitat use is an important first step for effective conservation planning. Species restricted to low-lying islands are at greatest risk from climate change-related sea level rise, and requirements for breeding and foraging habitat may determine their risk from tidal inundation. The endangered Micronesian Scrubfowl (Megapodius laperouse senex) is a model species for understanding these impacts. This species faces the cumulative challenges of tourist visitation, invasive species, and rising sea levels, yet little is understood about its habitat use in the Rock Islands Southern Lagoon Conservation Area (RISL) of Palau. We studied the habitat requirements of this mound-nesting …

Golden Eagle Dietary Shifts Following Wildfire And Shrub Loss Have Negative Consequences For Nestling Survivorship, Julie A. Heath, Michael N. Kochert, Karen Steenhof
Biology Faculty Publications and Presentations
Wildfires and invasive species have caused widespread changes in western North America’s shrub-steppe landscapes. The bottom–up consequences of degraded shrublands on predator ecology and demography remain poorly understood. We used a before–after paired design to study whether Golden Eagle (Aquila chrysaetos) diet and nestling survivorship changed following wildfires in southwestern Idaho, USA. We assessed burn extents from 1981 to 2013 and vegetation changes between 1979 (pre-burn) and 2014 (post-burn) within 3 km of Golden Eagle nesting centroids. We measured the frequency and biomass of individual prey, calculated diet diversity indexes, and monitored nestling survivorship at 15 territories in …

Morocco’s drylands cover over 90% of the land area; low and irregular rainfall and high potential evaporation contribute to extremely high-water deficits. These phenomena have greatly impacted rangeland hydrology and nomadic and transhumant pastoralism. To adapt to this predominant water deficit, the inhabitants of these areas have developed two forms of lifestyles, which include household and livestock mobility: (i) a pendulum movement for seasonal transhumance between the mountains and their bordering plains; and (ii) random nomadic mobility regulated by the sporadic frequency of rains and thus water availability. In both cases, this mobility is controlled by the degree of development …

Africa makes a relatively minor contribution to global greenhouse gas emissions compared with developed nations, yet the African continent will be increasingly vulnerable to climate change processes in the coming decades. Critical challenges include meeting basic needs for food, water, shelter, and other necessities without undermining biodiversity and ecosystem services. Coordination efforts to address multiple global change related stressors has generally occurred at the national level and taken an external approach, with national governments favoring collaboration with foreign-based NGOs and other international institutions. However, the involvement of actors at the local level correlates with decisions that are better adapted to …
Climate Change Policy Narratives And Pastoralist Predicaments In The Horn Of Africa: Insights From Ethiopia And Kenya, T. Campbell
Climate Change Policy Narratives And Pastoralist Predicaments In The Horn Of Africa: Insights From Ethiopia And Kenya, T. Campbell
IGC Proceedings (1977-2023)
Drawing on the findings of a two-country case study, this paper examines the discourses and narratives found in contemporary climate change and national development policy in Ethiopia and Kenya, the actors shaping those policy narratives, and in turn, their consequences for pastoralism. The research reveals that while concerns around climate change and calls for strengthening resilience of dryland communities have given a new impetus to pastoral development, old arguments and assumptions that depict pastoral areas, and pastoralists, as unproductive and in need of modernisation remain deeply embedded in policy making. These open up spaces for the state, investors, and local …
