Rhetorics Of Species Revivalism And Biotechnology – A Roundtable Dialogue, Eva Kasprzycka, Charlotte Wrigley, Adam Searle, Richard Twine
Rhetorics Of Species Revivalism And Biotechnology – A Roundtable Dialogue, Eva Kasprzycka, Charlotte Wrigley, Adam Searle, Richard Twine
Animal Studies Journal
This informal dialogue contextualises and explores contemporary practices of nonhuman animal gene-modification in de-extinction projects. Looking at recent developments in biotechnology’s role in de-extinction sciences and industries, these interdisciplinary scholars scrutinise the neoliberal impetus driving ‘species revivalism’ in the wake of the Capitalocene. Critical examinations of species integrity, cryo-preservation, techno-optimism, rewilding initiatives and projects aimed at restoring extinct animals such as the woolly mammoth and bucardo are used to map some of the necessary restructuring of conservation policies and enterprises that could secure viably sustainable – and just – futures for nonhuman animals at risk of extinction. The authors question …
Reflections On A Career Unplanned, Robert A. Glazer
Reflections On A Career Unplanned, Robert A. Glazer
Gulf and Caribbean Research
Sometimes life takes unexpected turns. I never planned to be a marine biologist; yet, after a long and unpredictable journey, that’s exactly where I found myself. After obtaining my B.S. in Fishery Biology from Colorado State University, I found myself meandering from job to job like a golden retriever following some vague scent. At first, I was hired by the Wyoming Game and Fish Department to work seasonally in Grand Teton National Park on the freshwater trout fisheries. Soon thereafter, I found myself cultivating oysters, clams, and other shellfish in California. The skills I developed there as an algologist led …
High Temperatures Adversely Affect The Hoverfly Episyrphus Balteatus(Diptera: Syrphidae) Fitness And Aphid Prey Consumption, Gregoire Noel, Jessica Caetano, Solene Blanchard, Antoine Boullis, Frederic Francis
High Temperatures Adversely Affect The Hoverfly Episyrphus Balteatus(Diptera: Syrphidae) Fitness And Aphid Prey Consumption, Gregoire Noel, Jessica Caetano, Solene Blanchard, Antoine Boullis, Frederic Francis
Turkish Journal of Zoology
Numerous studies have shown that an increase of environmental temperature could directly disturb insect larval development. Natural enemies of insect pests, particularly predators of aphid populations, are not spared. Following temperature predictions of Belgian climate change scenario, the goal of this study is to measure life-history traits, such as the mass, body length and aphid consumption (Acyrthosiphon pisum (Harris, 1776)) (Hemiptera: Aphididae) of Episyrphus balteatus (De Geer, 1776) (Diptera: Syrphidae) larvae under three constant temperature treatments (i.e. 20, 23, and 26 °C). We detected no significant differences between 20 °C and 23 °C on the hoverflies larval development, their aphidophagous …

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 …
Negative Impacts Of The Beef Industry: Lab-Grown Meat, Stephanie Grass
Negative Impacts Of The Beef Industry: Lab-Grown Meat, Stephanie Grass
WRIT: Journal of First-Year Writing
The beef industry is harmful to the environment and human health and alternative solutions must be implemented in order to mitigate the effects of climate change. Water and grain are used in agriculture in abundance despite the negative environmental effects it causes. Cattle are the biggest contributors to greenhouse gas emissions in the sector, also contributing to climate change. Antibiotics are used in large quantities without regard to potential future consequences. One potential solution for this problem is lab-grown beef, which demands very little from the consumer and would take pressure off the environmental issues the beef industry creates. Lab-grown …
Managing Urban Crow Populations In Japan, Tsuyoshi Yoda
Managing Urban Crow Populations In Japan, Tsuyoshi Yoda
Human–Wildlife Interactions
Crow (Corvus spp.) populations are increasing globally. This is cause for concern because overabundant crow populations can damage agricultural crops, harm native wildlife, and become a nuisance in urban areas. In Japan, the carrion (C. corone) and large-billed crow (C. macrorhynchos) can cause damage to crops and livestock. This damage is predicted to increase in Japan with climate change, especially when precipitation increases, inducing landscape changes that may favor crow populations and activities. In Japan, the primary control method used to manage crow damage is the destruction of nests by a crow control officer who …

Physiological Ecology Of Four Endemic Alabama Species And The Exotic Asiatic Weatherfish, Misgurnus Anguillicaudatus (Cantor, 1842), Lindsay M. White, Mark E. Meade, Benjamin A. Staton
Southeastern Fishes Council Proceedings
The occurrence of Asiatic Weatherfish, Misgurnus anguillicaudatus, in Alabama, a state known for its rich biodiversity, has generated concern among conservation managers. The current study used respirometry techniques to investigate the effects of increasing temperature on four native southeastern fishes (one cyprinid, two percids, and one elassomid) and the non-native M. anguillicaudatus. A minimum of five individuals of each species were used, and three experimental temperatures were chosen to represent spring and summer averages of northeast Alabama streams (15, 20, and 25°C). Overall, mean standard metabolic rates (SMRs) for M. anguillicaudatus were low (97.01, 127.75, and 158.50 mg …

Journal of Marine Science and Technology
Coastal zones located in populated and rapidly developing areas face high risks of natural and anthropogenic disasters. In this study, a framework was developed to determine the indicators of vulnerability to natural and anthropogenic disasters in Chuwei and Tamsui, two northern Taiwanese fishing villages in the coastal zone of the Tamsui River. The analytical hierarchy process (AHP) was used to determine the vulnerability indices of the locations, with experts evaluating the weights assigned to a range of criteria, namely hydrological data (such as sea surface temperature and sea level), stakeholder perceptions, and fishery data. These two villages have a considerably …

Predicting The Catch Potential Of Skipjack Tuna In The Western And Central Pacific Ocean Under Different Climate Change Scenarios, Kuo-Wei Yen, Nan-Jay Su, Tooreka Teemari, Min-An Lee, Hsueh-Jung Lu
Journal of Marine Science and Technology
Skipjack tuna (Katsuwonus pelamis) constitute an important migratory species that contributes significantly to the economy and the global fishery industry. Skipjack tuna play a vital role in the marine ecosystem, particularly in tropical waters of the western and central Pacific Ocean (WCPO). However, climate change may affect the characteristics of fishery resources, leading to substantial reallocation and reduction of the biomass of this species in the WCPO. In this study, catch and effort data for skipjack tuna were collected from a purse seine fishery and subsequently analyzed in combination with remote-sensing environmental variables and simulation data from climate models under …
Impact Of Climate Change On Shihmen Reservoir Water Supply, Tai-Yi Chu, Jyun-Long Lee, Wen-Cheng Huang
Impact Of Climate Change On Shihmen Reservoir Water Supply, Tai-Yi Chu, Jyun-Long Lee, Wen-Cheng Huang
Journal of Marine Science and Technology
This study evaluated the impact of climate change on the water supply of the Shihmen reservoir in northern Taiwan. Five downscaled general circulation models that represent the daily meteorological data of 2046-2065 were adopted. The future inflow of the Shihmen reservoir was estimated using the tank model. Subsequently, the water supply risk under the given demand and operating conditions was simulated and assessed. Compared with 2004-2011, the average annual precipitation of the Shihmen watershed in 2046-2065 is lower, particularly during the wet season (May-October). Therefore, the risk to the water supply will increase in the first cropping season (from March …
Estimated Effects Of Climate Change On The Reproductive Fitness Of The Northern Spotted Owl, Strix Occidentalis Caurina, Nadia Swit
The Downtown Review
In this paper, the trends for current and future climate change were utilized to evaluate the potential reproductive success of the Spotted Owl, particularly the Northern Spotted Owl (Strix occidentalis caurina) subspecies. As breeding season would exert additional stressors on the animal, a time period of five months, from January to June, was selected for the spring breeding season in which to evaluate temperature change. Previous research performed by Weathers and colleagues (2001) concerning the California Owl (Strix occidentalis occidentalis) formulated a thermodynamic equation that was utilized to compare the metabolic rate of the owl at …
Viewing The Status Of Virginia’S Environment Through The Lens Of Freshwater Fishes, Paul L. Angermeier, Michael J. Pinder
Viewing The Status Of Virginia’S Environment Through The Lens Of Freshwater Fishes, Paul L. Angermeier, Michael J. Pinder
Virginia Journal of Science
We summarize a range of topics related to the status of Virginia’s freshwater fishes, their reflection of environmental quality, and their contribution to human wellbeing. Since 1994 the list of extant Virginia fishes has lengthened from 210 species to 227 species, mostly due to taxonomic reorganizations. Virginia’s list of Species of Greatest Conservation Need currently contains 96 fish species, predominated by darters (32 species) and minnows (28 species). Increasing trends in species rarity and threats to fishes suggest that Virginia’s aquatic environment is becoming less hospitable for fishes. Prevailing anthropogenic threats to fishes include agriculture, urban development, mineral extraction, forestry, …
Impact Of Warm Weather Events On Prolongation Of The Life Cycle Ofstomaphis Walker (Hemiptera, Aphididae, Lachninae), Lukasz Depa, Artur Taszakowski, Mariusz Kanturski
Impact Of Warm Weather Events On Prolongation Of The Life Cycle Ofstomaphis Walker (Hemiptera, Aphididae, Lachninae), Lukasz Depa, Artur Taszakowski, Mariusz Kanturski
Turkish Journal of Zoology
Termination of the life cycle of sexually reproducing aphids usually takes place in autumn, during October and November, in the climatic conditions of Central Europe. However, episodes of warm weather are suspected to trigger prolongation of the life cycle. Observations of Stomaphis spp. İn early winter of 2013/2014 in southern Poland support this thesis. Surprisingly, adult females of two species were collected as late as early January and early March. High daily temperatures during this period were the probable cause of aphid survival, despite frosty nights. The possibility of the influence of warm weather episodes (higher temperature) on prolongation of …
Effect Of Increased Water Temperature On Warm Water Fish Feeding Behavior And Habitat Use, Eric Walberg
Effect Of Increased Water Temperature On Warm Water Fish Feeding Behavior And Habitat Use, Eric Walberg
Journal of Undergraduate Research at Minnesota State University, Mankato
Global warming could cause changes in species behavior and life history. Stream fish may be significantly affected by climate change because individuals are restricted in their movements by water systems and other physical factors, preventing migration to locations more thermally suitable. The effect of warmer waters on stream fish could change behavior and affect the fish species survival and ultimately ecosystem function. During my experiment I observed the effects of increased water temperature on the feeding behavior and habitat use of two native Minnesota fish species, black crappie (Pomoxis nigromaculatus) and black bullhead (Ameiurus melas). An increase of 2oC over …

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
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 …
