Large brains and behavioural innovation are positively correlated, species-specific traits, associated with the behavioural flexibility animals need for adapting to seasonal and unpredictable habitats. Similar ecological challenges would have been important drivers throughout human evolution. However, studies examining the influence of environmental variability on within-species behavioural diversity are lacking despite the critical assumption that population diversification precedes genetic divergence and speciation. Here, using a dataset of 144 wild chimpanzee (Pan troglodytes) communities, we show that chimpanzees exhibit greater behavioural diversity in environments with more variability - in both recent and historical timescales. Notably, distance from Pleistocene forest refugia is associated …
Implementing Nepa In The Age Of Climate Change, Jayni Foley Hein, Natalie Jacewicz
Implementing Nepa In The Age Of Climate Change, Jayni Foley Hein, Natalie Jacewicz
Michigan Journal of Environmental & Administrative Law
The national government has a crucial role to play in combating climate change, yet federal projects continue to constitute a major source of United States greenhouse gas emissions. Under the National Environmental Policy Act, agencies must consider the environmental impacts of major federal actions before they can move forward. But agencies frequently downplay or ignore the climate change impacts of their projects in NEPA analyses, citing a slew of technical difficulties and uncertainties. This Article analyzes a suite of the most common analytical failures on the part of agencies with respect to climate change: failure to account for a project’s …

Faculty Publications
The conservation of coastal wetland ecosystems, like mangrove forests and salt marshes, represents a critical strategy for mitigating atmospheric emissions and climate change in the 21st century. Yet the existence of these environments is threatened by human-induced disturbances, namely deforestation and accelerated sea-level rise. Coastal systems maintain surface elevation in response to sea-level rise through a combination of physical and biological processes both above and below the ground surface. The quantification and relative contribution of belowground process controls (e.g., seasonal water content, organic matter decomposition) on surface elevation change is largely unexplored but crucial for informing coastal ecosystem sustainability. To …
Thermal Stress-Related Spatiotemporal Variations In High-Latitude Coral Reef Benthic Communities, Nicholas P. Jones, Joana Figueiredo, David S. Gilliam
Thermal Stress-Related Spatiotemporal Variations In High-Latitude Coral Reef Benthic Communities, Nicholas P. Jones, Joana Figueiredo, David S. Gilliam
Marine & Environmental Sciences Faculty Articles
High-latitude coral reef communities have been postulated as the first areas to undergo reorganisation under climate change. Tropicalisation has been identified in some high-latitude communities and is predicted in others, but it is unclear how the resident benthic taxa are affected. We conducted a long-term (2007–2016) assessment of changes to benthic community cover in relation to thermal stress duration on the Southeast Florida Reef Tract (SEFRT). Thermal stress events, both hot and cold, had acute (thermal stress duration affected benthic cover that year) and chronic (thermal stress duration affected benthic cover the following year) impacts on benthic cover. Chronic heat …

Aspen Bibliography
Based on a generated database of 413 sample plots, with definitions of stand biomass of the genus Populus spp. in Eurasia, from France to Japan and southern China, statistically significant changes in the structure of forest stand biomass were found, with shifts in winter temperatures and average annual precipitation. When analyzing the reaction of the structure of the biomass of the genus Populus to temperature and precipitation in their transcontinental gradients, a clearly expressed positive relationship of all components of the biomass with the temperature in January is visible. Their relationship with precipitation is less clear; in warm climate zones, …
Examining Dissolved Gases In A Changing Climate, Allison Staniec
Examining Dissolved Gases In A Changing Climate, Allison Staniec
Doctoral Dissertations
Changing climate scenarios predict a variety of effects across land, ocean, and atmosphere. In this dissertation the effect of several climate change related phenomena on dissolved gases in the coastal ocean and across the ocean-atmosphere interface is examined. Warming temperature, as predicted by the IPCC (2014), has direct impacts on the capacity of water to act as a reservoir for dissolved gases through its effect on their solubility (Chang, 2010). The first portion of this dissertation addresses dissolved gases in a coastal estuary, where warming is expected to be accelerated relative to the open ocean. A representative gas, oxygen, is …
A Regional Vulnerability Assessment For The Dungeness Crab (Metacarcinus Magister) To Changing Ocean Conditions: Insights From Model Projections And Empirical Experiments, Halle Berger
Master's Theses
Among global coastal regions, the Northern California Current System (N-CCS) is already experiencing effects from ocean acidification and hypoxia during the summer, primarily due to the region’s seasonal upwelling, current systems, and high productivity. Oxygen, pH, and temperature conditions are expected to become more stressful with continued fossil fuel emissions under global climate change, posing a serious threat to the region’s fisheries. N-CCS fishing communities rely heavily on the economically and culturally important Dungeness crab (Metacarcinus magister). The fishery is currently sustainably managed, but potential negative impacts from changing ocean conditions on Dungeness crab life stages and populations …

Towards Green Economy: Green Bonds, U. Berdiyev
International Finance and Accounting
The article aims to shed light on a recent financial innovation tool – green bonds on the way to less carbon economy, in which expectations, impacts and preferences versus other traditional types of bonds resulting from green bonds are attempted to reveal. Having learned many cases of green bond issues, especially in Asian and African countries, we can support the view that these bonds can potentially play a key role in greening the economy without penalizing financially the issuers.

Harmful Algal Blooms: Dominance In Lakes And Risk For Cyanotoxin Exposure In Food Crops, Austin D. Bartos
Harmful Algal Blooms: Dominance In Lakes And Risk For Cyanotoxin Exposure In Food Crops, Austin D. Bartos
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Climate change and human activities are promoting the dominance of a photosynthetic family of aquatic bacteria, cyanobacteria. Blooms of cyanobacteria are not only a visual nuisance but can produce a variety of cyanotoxins than can harm the liver, skin, and nervous system of animals and humans. We analyzed lakes in the contiguous United States and found that between 2007 and 2012, the number of lakes that produced measurable quantities of cyanotoxins increased from 33% to 45%. Nitrogen and phosphorus pollution were the main drivers of cyanobacteria blooms and toxin production between these years. Many of these lakes and reservoirs are …

Artisanal Marine Fisheries And Climate Change In The Region Of Lima, Peru, Edelina Coayla
Artisanal Marine Fisheries And Climate Change In The Region Of Lima, Peru, Edelina Coayla
Journal of Ocean and Coastal Economics
This study explores the relationship between climate change and artisanal marine fisheries in the region of Lima, Peru. From the perspective of the economics of climate change and renewable marine resources, the methods of correlations and bivariate regression are employed. A negative relationship is found between the increase in the sea surface temperature (SST) and the marine fishery catches landed at the ports of the Lima region (2004-2017).The higher the SST, the lower fishing effort. It was also found that the SST significantly influences the gross added value of fishing. To reduce the vulnerability of artisanal marine fisheries, the main …

Climatic Variability And Climate Change: U.S. College Freshmen Attitudes And Spatio-Temporal Effects On Cavity-Nesting Passerines, Sara Elizabeth Harrod
Climatic Variability And Climate Change: U.S. College Freshmen Attitudes And Spatio-Temporal Effects On Cavity-Nesting Passerines, Sara Elizabeth Harrod
Student Theses and Dissertations
Despite the scientific consensus that human activities are the primary cause, many people deny the problem of climate change. If mitigation efforts are to be successful, we need to determine young individuals’ attitudes toward and knowledge of climate change. Successful mitigation efforts are important for humans, as well as wildlife and the environment. Wildlife populations are already being affected, with many documented cases of negative impacts. Effects on populations can occur through impacts on demographic parameters, and if parameters are synchronized across species or populations, this could prove disastrous if climate change negatively affects these parameters. Here, I surveyed first-semester …

Habitat Fragmentation And Range Margin Effects On Dispersal And Interactions Between Competitors, Rachel Roxann Harman
Habitat Fragmentation And Range Margin Effects On Dispersal And Interactions Between Competitors, Rachel Roxann Harman
LSU Doctoral Dissertations
Dispersal is a fundamental process that affects local and regional dynamics, including population persistence, range expansion, and interspecific interactions, particularly as disturbance through habitat fragmentation and climate change. Here, my main objective was to ascertain how fragmentation affects dispersal and the interactions of competitors within the local patch and regional landscape. In my second chapter, I assessed dispersal through a literature review and population persistence model to examine the breadth and frequency of different density-emigration forms that occur in nature, including forms that are not prevalent in the literature. I conclude that these rare forms have important population dynamic consequences …

Biological Flora Of The Tropical And Subtropical Intertidal Zone: Literature Review For Rhizophora Mangle L., Hudson R. Deyoe, Robert I. Lonard, Frank W. Judd, Richard Stalter, Ilka Feller
School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)
Rhizophora mangle L. is a tropical and subtropical mangrove species that occurs as a dominant tree species in the intertidal zone of low-energy shorelines. Rhizophora mangle plays an important role in coastal zones as habitat for a wide range of organisms of intertidal food webs, as a natural barrier to coastal erosion, and as carbon sequestration. A review of mangrove literature has been performed, but a review specifically on red mangroves has not. The approach was to cover a broad range of topics with a focus on topics that have seen significant work since the 1970s. This review includes a …
Understanding The Influence Of Changing Climate On Mycotoxin Contamination Of Food And Indoor Fungi-Mediated Respiratory Illness, Mayomi Helen Omebeyinje
Understanding The Influence Of Changing Climate On Mycotoxin Contamination Of Food And Indoor Fungi-Mediated Respiratory Illness, Mayomi Helen Omebeyinje
Theses and Dissertations
Over the years, climate change has been a major core issue in public and environmental health. The World Health Organization (WHO) estimated that about 250,000 additional death per year would be attributed to climate change between 2030 and 2050 if this situation persists. Since our population depends on (but not limited to) the availability of clean water, good air quality, and exposure to environmental hazards/pathogens, the overall health impact caused by climate change is likely to be overwhelming in the nearest future. This dissertation explored the influence of climate change on fungi diseases and pathogenesis after severe weather conditions (hurricanes …

Light And Temperature Mediate Algal Simulation Of Heterotrophic Activity On Decomposing Leaf Litter, Cody A. Pope, Halvor M. Halvorson, Robert H. Findlay, Steven N. Francoeur, Kevin A. Kuehn
Faculty Publications
- Recent evidence suggests that periphytic algae stimulate plant litter heterotrophs (fungi and bacteria) in the presence of light, but few studies have tested whether this stimulation varies across gradients of light, which may covary with temperature.
- We exposed field‐conditioned Typha domingensis litter to fully‐crossed, short‐term gradients of temperature (15, 20, 25, and 30°C) and light (0, 25, 53, 123, and 388 µmol quanta m−2 s−1) and measured responses of litter‐associated algal, fungal, and bacterial production rates and β‐glucosidase, β‐xylosidase, and phenol oxidase enzyme activities in the laboratory.
- Increased light stimulated algal production rates, from immeasurable production under …

Recommendations For Early Phases Of Engaging Communities In Climate Change Adaptation, Richard R. Plate, Martha C. Monroe, Claire Friedrichsen, Alison W. Bowers, Willandia A. Chaves
Journal of Human Sciences and Extension
Communities across the globe have begun planning for and adapting to climate change. Cooperative Extension Service professionals are in a unique position to use the resources available to them to facilitate climate change adaptation in their communities. Adaptation planning is a local activity that must be context specific. However, general recommendations can be made to help facilitate the planning process. In this study, we conducted a systematic review of research about climate change adaptation in communities to explore ideas that contribute to successful adaptation-planning communication. We identified and reviewed 50 peer-reviewed articles that described various outreach efforts to engage communities …

Walker’s Manihot, Manihot walkerae, is an endangered plant that is endemic to the Tamaulipan thornscrub ecoregion of extreme southern Texas and northeastern Mexico. M. walkerae populations are highly fragmented and are found on both protected public lands and private property. Habitat loss and competition by invasive species are the most detrimental threats for M. walkerae; however, the effect of climate change on M. walkerae’s geographic distribution remains unexplored and could result in further range restrictions. Our objectives are to evaluate the potential effects of climate change on the distribution of M. walkerae and assess the usefulness of natural protected areas …
The Ecological Impacts Of Changing Rainfall On The Arabian Peninsula, Zahra Ahmed M Alsomali
The Ecological Impacts Of Changing Rainfall On The Arabian Peninsula, Zahra Ahmed M Alsomali
Civil and Environmental Theses
The Arabian Peninsula is one of the hottest and driest regions in the world, and with climate change, not only is it getting hotter, it is also getting drier. It may be that the desert species here are well-adapted to dry conditions, in which case they may be able to withstand the changes, but it may be that desert species are already challenged by the extremely dry conditions. Here, data from 167 published studies were used to look at whether desert species were living below their optimum rainfall, and to compare the findings with species in other biomes. In all …
Effect Of Climate Change In 50-Years Period On Grassland Productivity In Central Poland, Piotr Goliński, Marek Czerwinski, Barbara Golińska
Effect Of Climate Change In 50-Years Period On Grassland Productivity In Central Poland, Piotr Goliński, Marek Czerwinski, Barbara Golińska
IGC Proceedings (1977-2023)
In Central Europe, the climate change is predicted to bring more rainfall in winter, less rainfall in summer, and an increased drought risk (Trnka et al., 2011). Smit et al., (2008) reported that significant drops in grassland productivity can usually be attributed to drier summers. Also in Poland, the most important abiotic factor limiting grassland productivity is water shortage and its distribution during vegetative season. Indicating the influence of climate on grass vegetation growth could be an important tool in grassland management on the national, regional and single grassland scales. The aim of the study was to evaluate …

Climate Change Adaptation In Vulnerable Crop And Livestock Production Systems In Mgeta, Tanzania, Leif Jarle Asheim, Zabron C. Nziku, Lars O. Eik, Dismas Mwaseba, George C. Kifaro
IGC Proceedings (1977-2023)
Awareness regarding effects of climate change on the environment and livelihoods is becoming more apparent than at any time before (Elisha, 2006). Among the farming systems that have attracted the attention in Tanzania, are those in Mgeta in thehigh altitude water catchment area in the Uluguru Mountains. Land degradation have been widely reported in Mgeta (Ponte, 2001), and is currently threatening the source of water for domestic use and livelihoods of the local communities. Increased occurrence of droughts and dry spells during the growing seasons might reinforce the problem. A robust cropping system toreplace the erosion vulnerable vegetables seems needed …

Uncovering The Role Of Symbiodiniaceae Assemblage Composition And Abundance In Coral Bleaching Response By Minimizing Sampling And Evolutionary Biases, Timothy D. Swain, Simon Lax, Vadim Backman, Luisa A. Marcelino
Marine & Environmental Sciences Faculty Articles
Background
Biodiversity and productivity of coral-reef ecosystems depend upon reef-building corals and their associations with endosymbiotic Symbiodiniaceae, which offer diverse functional capabilities to their hosts. The number of unique symbiotic partners (richness) and relative abundances (evenness) have been hypothesized to affect host response to climate change induced thermal stress. Symbiodiniaceae assemblages with many unique phylotypes may provide greater physiological flexibility or form less stable symbioses; assemblages with low abundance phylotypes may allow corals to retain thermotolerant symbionts or represent associations with less-suitable symbionts.
Results
Here we demonstrate that true richness of Symbiodiniaceae phylotype assemblages is generally not discoverable from …
