Atlantic Sailfish (Istiophorus Albicans) Distribution Off The East Coast Of Florida From 2003 To 2018 In Response To Sea Surface Temperature, Meredith M. Pratt Jan 2021

Atlantic Sailfish (Istiophorus Albicans) Distribution Off The East Coast Of Florida From 2003 To 2018 In Response To Sea Surface Temperature, Meredith M. Pratt

Mako: NSU Undergraduate Student Journal

The Atlantic sailfish (Istiophorus albicans) ranges from 40°N to 40°S in the Western Atlantic Ocean and has great economic and recreational value for sport fishers. Off the east coast of Florida, recreational fishing boats often target this species due to its size, speed and strength. This project aimed to determine the relationship between sea surface temperature (SST) and the distribution of Atlantic sailfish caught and released over a fifteen-year period (2003 to 2018). Tagging information was collected from The Billfish Foundation and NOAA who have the most extensive programs for billfish. Using the time and location of each ...

Not Too Hot, Not Too Cold, But Moderately Variable: The Influence Of Environmental Variability On Coral Thermal Tolerance, Courtney Nicole Klepac Dec 2020

Not Too Hot, Not Too Cold, But Moderately Variable: The Influence Of Environmental Variability On Coral Thermal Tolerance, Courtney Nicole Klepac

Biological Sciences Theses & Dissertations

Anthropogenic climate change is causing an increase in the frequency and severity of marine heat waves, resulting in declining health of coral reef ecosystems worldwide. Coral bleaching events – the breakdown in symbiosis between the coral host and their intracellular photosynthetic algae – are increasingly common in recent years and contribute to widespread losses in coral cover. However, bleaching and heat stress responses vary across spatial scales both within and among coral species. Coral populations native to highly variable environments can have greater bleaching resistance than corals from more stable habitats and corals transplanted into these variable reef sites can increase their ...

Spatial And Temporal Dynamics Of Human–Wildlife Conflicts In The Kenya Greater Tsavo Ecosystem, Joseph M. Mukeka, Joseph O. Ogutu, Erustus Kanga, Eivin Røskaft

Human–Wildlife Interactions

Biodiversity conservation in developing countries is faced with many and mounting challenges, including increasing human–wildlife conflicts (HWCs). In Africa and other developing countries, increasing HWCs, particularly those adjacent to protected areas, can adversely affect local stakeholder perceptions and support for conservation. We analyzed HWC reports for multiple wildlife species compiled >23 years (1995–2017) from the Greater Tsavo Ecosystem (GTE) in Kenya to determine HWC trends. The GTE is the largest protected area in Kenya, covering 22,681 km2. Overall, 39,022 HWC incidents were reported in 6 GTE regions (i.e., Taveta, Mutomo, Kibwezi, Rombo, Galana, Bachuma ...

Thermal Stress-Related Spatiotemporal Variations In High-Latitude Coral Reef Benthic Communities, Nicholas P. Jones, Joana Figueiredo, David S. Gilliam Aug 2020

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 ...


Effect Of Climate Change In 50-Years Period On Grassland Productivity In Central Poland, Piotr Goliński, Marek Czerwinski, Barbara Golińska May 2020

Effect Of Climate Change In 50-Years Period On Grassland Productivity In Central Poland, Piotr Goliński, Marek Czerwinski, Barbara Golińska

International Grassland Congress Proceedings

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 the effect ...


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 May 2020

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

International Grassland Congress Proceedings

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 May 2020

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 direct ...


Frost Tolerance, Deacclimation And Reacclimation Traits In Perennial Ryegrass, Mats Höglind, Hans Martin Hanslin May 2020

Frost Tolerance, Deacclimation And Reacclimation Traits In Perennial Ryegrass, Mats Höglind, Hans Martin Hanslin

International Grassland Congress Proceedings

The ability of perennial grasses to harden and maintain frost tolerance throughout the winter is crucial for winter survival. This includes the ability to resist deacclimation during transient mild spells in winter, and the ability to reacclimate when cold temperatures return. The latter traits are especially critical in regions with cycles of freezing and thawing, and lack of a stable, insulating snowcover that can protect the plants from extreme air temperatures. Such conditions are typical for many coastal areas in Northern Eurasia and America, such as the southwestern coast of Norway. The climate is changing and one of the consequences ...

Importance Of Grassland Management For Carbon Sequestration And To Mitigate Climate Change: A Review, Poonam Yadav, Sheela Choudhary, Sunil Dutt Choudhary, Praveen Kaushik

International Grassland Congress Proceedings

Grasslands, including rangelands, shrub lands, pastureland, and cropland sown with pasture and fodder crops, covered approximately 3.5 billion ha in 2000, representing 26 percent of the world land area and 70 percent of the world agricultural area, and containing about 20 percent of the world’s soil carbon stocks (Ramankutty et al., 2008). All ecosystems- forested ecosystems, agro-ecosystems, grassland, ecosystems etc. take up atmospheric CO2 and mineral nutrients and transform them into organic products In undisturbed ecosystems, the carbon balance tends to be positive: carbon uptake through photosynthesis exceeds losses from respiration, even in mature, old-growth forest ecosystems ...

Simulating The Effect Of The Climate Change, Genotypes And Management On The Productivity Of Forage Cowpea In Semi-Arid Regions Of India, Suchit K. Rai, Sunil Kumar, D. Deb

International Grassland Congress Proceedings

Climate variability and change due to increase in green house gases concentration and the resultant increase in temperature has led to notable changes in different sectors including water and agriculture which would impact food security (Rai et al., 2014) in many regions of the developing world, which are largely dependent on rainfed and labor intensive agricultural production (Ziervogel and Calder, 2003). Eco-physiological models are widely used especially the potential impacts of climate change (Gitay et al., 2001; White et al., 2011). The cowpea (Vigna unguiculata (L.) Walp.) is an annual herbaceous legume cultivated for its edible seeds or for fodder ...

The north-eastern states of India specially Arunachal Pradesh, one of the bio-diversity hotspot, is expected to be greatly affected by climate change. Climate change will not only adversely impact the biodiversity of Arunachal Pradesh, but also affect the livelihood of local communities as they fully dependent on the natural resources. The Monpa is a primitive tribe inhabiting parts of West Kameng and Tawang district of Arunachal Pradesh. The pastoral nomad of the Monpa tribe is popularly known as Brokpa. Transhumance system of livestock mainly yak (Poephagus grunniens L.) rearing is their main source of livelihood. In recent past, challenges of ...


A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, Heather Navle May 2020

A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, Heather Navle

Master's Projects and Capstones

Wildfires in the mixed conifer forests of California’s Sierra Nevada have been a common and natural disturbance for thousands of years, historically occurring every 3 to 30 years. The flora and fauna of the mixed conifer forest have evolved to depend on low to moderate severity wildfires for reproduction, foraging, and habitat. However, the Sierra Nevada has experienced dramatic environmental changes over the past ~150 years as a result of three main factors: wildfire suppression, climate change, and habitat loss. Because of the threat wildfires pose to human lives, property and timber harvest, they have been suppressed to an ...
