Synonyms and Other Names: Amur snakehead, eastern snakehead, ocellated snakehead, snakehead, Ophicephalus argus Cantor, ; Ophiocephalus argus kimurai Shih, ; Ophicephalus argus warpachowskii Berg, ; Ophicephalus pekinensis Basilewsky, Courtenay and Williams provide a larger list, including names used in other languages.
Taxonomy: available through www. Identification: A long, thin fish with a single dorsal fin running the length of the fish. Overall color is brown with dark blotches. It has a somewhat flattened head with eyes located in a dorsolateral position on the anterior part of the head; anterior nostrils are present and tubular; dorsal and anal fins are elongated, and all fins are supported only by rays Courtenay and Williams Males are darker in color, and have a broader head, as compared to females Gascho Landis and Lapointe Juveniles have a similar color and pattern as the adults.
Size: Maximum size exceeds 85 cm 33 inches. It is native to all but the northeastern regions of Korea, as well as the rivers of China, southward and southwestward to the upper tributaries of the Yangtze River basin in northeastern Yunnan Province Courtenay and Williams Ecology: Channa argus is an obligate air-breather, capable of survival in poorly oxygenated waters.
This species does show some seasonal changes microhabitat selection and preference, utilizing deeper water in winter months and shallow areas with macrophytes during the spawning season Lapointe et al. It can adapt to a wide range of aquatic environments, as evidenced by the spread of reproducing, introduced populations throughout Asia and Japan. Reduced metabolism and oxygen demand at low temperatures allows this species to survive extended periods of ice cover Frank , in Courtenay and Williams However, the northern snakehead was eradicated from the Crofton pond in Maryland where it was oritinally established.
The species is well established in the Potomac River and several of its tributaries in Virginia and Maryland Starnes et al. Although young fish were found, the status of the Philadelphia population is uncertain. Officials believe fish may have gotten into the lower Schuylkill River and Delaware River in Pennsylvania and see no practical means to eradicate them.
In March , the population in Little Piney Creek drainage received an eradication attempt with the application of rotenone to more km of creeks, ditches, and backwaters. However, more snakeheads have been found since this effort L. Holt, pers. The population in Catlin Creek, New York was also treated with rotenone.
Vector-Borne Disease The transmission of vector-borne diseases, which are spread by the bite of an animal such as a mosquito or tick, is complex and depends on a number of factors, including weather and climate, vegetation, animal host populations, and human activities Ch.
Aedes aegypti mosquitoes can spread several important diseases, including dengue fever, chikungunya, and Zika fever. The Southeast is the region of the country with the greatest potential mosquito activity. Warming temperatures have the potential to expand mosquito habitat and disease risk.

Infrastructure Infrastructure, particularly roads, bridges, coastal properties, and urban drainage, is vulnerable to climate change and climate-related events see Key Message 2 see also Ch.
See Sweet et al. Source: adapted from Sweet and Park Local sea level rise has shifted the curve closer to the point where high tide flooding begins based on warning thresholds established by the National Weather Service.
This shows why many more high tide flood events occur now than they did in the past increase of 6 flood days per year. Source: adapted from Sweet et al. Floodwaters can get deep enough to stall vehicles. This tunnel crosses a portion of downtown Charleston feet underground and is designed to rapidly convey storm water to the nearby Ashley River.

Some of these totals exceeded the year and 1,year return period amounts rainfall amounts that would be expected to have only a 0. Extreme precipitation events will likely increase in frequency in the Southeast. Source: CISA This photo shows a neighborhood in North Charleston after the event with knee-deep flooding. These maps show the mean projected changes in the plant hardiness zones, as defined by the U.
Based on these projected changes, freeze-sensitive plants, like oranges, papayas, and mangoes, would be able to survive in new areas. Mangrove forests are sensitive to freezing temperatures and are expected to expand northward at the expense of salt marshes. The figure shows the relationship between temperature and the percentage area dominated by mangrove forests.
Mangrove expansion would entail a grassland-to-forest conversion, which would affect fish and wildlife habitat and many societal benefits. Source: adapted from Osland et al.

Changing Patterns of Fire In the Southeast region, changing fire regimes defined by factors including frequency, intensity, size, pattern, season, and severity are expected to have a large impact on natural systems.

Diverse Rural Regions Urban and rural areas exist along a continuum from major metro areas to suburbs, small towns, and lightly populated places. Projections indicate an annual average of million labor hours lost per year in the Southeast by with models ranging from million to million labor hours.
These industries are defined as agriculture, forestry, and fishing; hunting, mining, and construction; manufacturing, transportation, and utilities. Source: adapted from EPA Compounding Stresses and Constraints to Adaptation The people of the rural Southeast confront a number of social stresses likely to add to the challenges posed by increases in climate stresses. Rural counties experiencing persistent poverty are concentrated in the Southeast, where the need for additional cooling is expected to increase at higher rates than other areas of the country by mid-century.
Description of evidence base Multiple studies have projected that urban areas, including those in the Southeast, will be adversely affected by climate change in a variety of ways.
Description of confidence and likelihood There is very high confidence that southeastern cities will likely be impacted by climate change, especially in the areas of infrastructure and human health. Description of evidence base Multiple lines of research have shown that global sea levels have increased in the past and are projected to continue to accelerate in the future due to increased global temperature and that higher local sea level rise rates in the Mid-Atlantic and Gulf Coasts have occurred.
Description of confidence and likelihood There is high confidence that flood risks will very likely increase in coastal and low-lying regions of the Southeast due to rising sea level and an increase in extreme rainfall events.
Description of evidence base Winter temperature extremes, fire regimes, sea levels, hurricanes, rainfall extremes, drought extremes, and warming ocean temperatures greatly influence the distribution, abundance, and performance of species and ecosystems. Description of confidence and likelihood There is high confidence that climate change e. Description of evidence base Analysis of the sensitivity of some manufacturing sectors to climate changes anticipates secondary risks associated with crop and livestock productivity.

Arcadia Publishing, Aug 6, - Photography - pages. The population was 8 at the census.
We have a 32' Monterey that fits nicely even when water levels are 4' below full pool. For example, Lake Lanier has gone through a series of years with low water then full again. This is especially helpful when the lake is at lower levels as obstructions appear in what might otherwise appear to be very open water. The forms create an artificial reef that divers can swim down and see.
