Seasonal Abundance Of Epiphytic Dinoflagellates Around Coastal Waters Of Jeju Island, Korea, Md. Mahfuzur Rahman Shah, So-Jeong An, Joon-Baek Lee Dec 2013

Seasonal Abundance Of Epiphytic Dinoflagellates Around Coastal Waters Of Jeju Island, Korea, Md. Mahfuzur Rahman Shah, So-Jeong An, Joon-Baek Lee

Journal of Marine Science and Technology

The seasonal abundance of epiphytic dinoflagellates in the intertidal zone of Jeju Island, Korea was quantitatively estimated by monthly collection of macroalgal samples (Rhodophyta, Phaeophyta, and Chlorophyta) from six sampling locations from July 2012 to June 2013. Ten epiphytic dinoflagellate taxa, including eight potentially toxic species Amphidinium carterae, A. operculatum, Gambierdiscus sp., Ostreopsis ovata, Prorocentrum concavum, P. emarginatum, P. lima, and P. rhathymum, were identified. Two Amphidinium and three Prorocentrum species are newly recorded in Korean coastal waters. A significant change in seasonal abundance was recorded with maximum (751.82 ± 223.12 cells g-1 wet weight of algae; cells g-1 hereafter) …


Fishing Vs. Climate Change: An Example Of Filefish (Thamnaconus Modestus) In The Northern East China Sea, Sukgeun Jung, Hyung Kee Cha Dec 2013

Fishing Vs. Climate Change: An Example Of Filefish (Thamnaconus Modestus) In The Northern East China Sea, Sukgeun Jung, Hyung Kee Cha

Journal of Marine Science and Technology

The main cause of annual fluctuations in catch and species composition of fisheries is usually uncertain, but a prevailing view has been that fishing effects are more critical than environmental variability. Filefish is a good anecdote: many Korean fisheries scientists have attributed the sudden collapse of Korean filefish fisheries in the early 1990s to overfishing, especially by trawl fisheries in the northern East China Sea (NECS). However, interdisciplinary researches have revealed that climate-driven, multi-decadal variability in oceanic conditions impacts both fish and fisheries around the world. To test the two alternative hypotheses (i.e., fishing and climate) as the major cause …


Collaborative Research: Globec Pan-Regional Synthesis: End-To-End Energy Budgets In Us-Globec Regions, Andrew C. Thomas Aug 2013

Collaborative Research: Globec Pan-Regional Synthesis: End-To-End Energy Budgets In Us-Globec Regions, Andrew C. Thomas

University of Maine Office of Research Administration: Grant Reports

The research addresses the overarching question: are marine food webs leading to fisheries controlled from the top-down, the bottom up, or a combination of the two? To address this question we will (1) compare end-to-end energy budgets of the 4 US-GLOBEC study regions in the context of top-down v. bottom-up forcing, (2) assess the skills of the regional models in capturing basic material fluxes, (3) extract diagnostics from the regional models that will be used to evaluate the effects of climate change and fishing pressure across GLOBEC regions and (4) develop quantitative methods to compare the diagnostics. The major successes …

Colorado River Cutthroat Trout Habitat Resistance And Resilience To Climate Change, Kate H. Olsen May 2013

Colorado River Cutthroat Trout Habitat Resistance And Resilience To Climate Change, Kate H. Olsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Government agencies and private organizations spend large amounts of public money attempting to return ecosystems to a more natural state, which have often been harmed or even destroyed as a result of modern development. Colorado River cutthroat trout, Oncorhyncus clarki pleuriticus, are a subspecies of cutthroat trout. Cutthroat trout live in the Rocky Mountains of the western United States. The population of this particular subspecies has been severely reduced by human actions, and currently only 12% of its historic populations still exist. To improve the condition of cutthroat trout, fisheries professionals and biologists are working to restore natural populations. …


Climate Change Adaptation Chapter: Marshfield, Massachusetts, Joshua H. Chase, Jonathan G. Cooper, Rory Elizabeth Fitzgerald, Filipe Antunes Lima, Sally R. Miller, Toni Marie Pignatelli Feb 2013

Climate Change Adaptation Chapter: Marshfield, Massachusetts, Joshua H. Chase, Jonathan G. Cooper, Rory Elizabeth Fitzgerald, Filipe Antunes Lima, Sally R. Miller, Toni Marie Pignatelli

Sally Miller

Climate change, understood as a statistically significant variation in the mean state of the climate or its variability, is the greatest environmental challenge of this generation (Intergovernmental Panel on Climate Change, 2001). Marshfield is already being affected by changes in the climate that will have a profound effect on the town’s economy, public health, coastal resources, natural features, water systems, and public and private infrastructure. Adaptation strategies have been widely recognized as playing an important role in improving a community’s ability to respond to climate stressors by resisting damage and recovering quickly. Based on review of climate projections for the …


Ecology And Conservation Of The Montane Forest Avian Community In Northeastern North America, William V. Deluca Feb 2013

Ecology And Conservation Of The Montane Forest Avian Community In Northeastern North America, William V. Deluca

Open Access Dissertations

Montane forests provide habitat for unique assemblages of flora and fauna that contribute significantly to a region’s biodiversity. Previous work indicates that montane forest ecosystems are exceedingly vulnerable to a host of anthropogenic stressors including climate change, atmospheric deposition, and recreation, to name a few. Montane forests and other high elevation ecosystems are considered to be among the first and most severely impacted by climate change. It is therefore, imperative to evaluate anthropogenic impacts on montane ecosystems and maintain reliable monitoring methods that are capable of tracking potential shifts in the distribution of species dependent on these systems. I surveyed …
