Charles Littnan is an American conservation biologist. He is the divisional director at the National Oceanic and Atmospheric Administration (NOAA) in Hawaii. He works in the Protected Species Division and is the lead scientist in the Hawaiian Monk Seal Research Program. Education Charles Littnan received his Bachelor's degree in Marine Biology from Texas A&M University at Galveston and then went on to get his PhD in Environmental Sciences from Macquarie University in Australia. While getting his PhD in 2004, his thesis focused on the fisheries interactions of Australian fur seals in the eastern Victorian shelf waters. Career Littnan is a conservation biologist who studies marine mammal ecology, endangered species, climate change, and science communication. His primary work focuses on the conservation and ecology of the endangered Hawaiian monk seals. He has spent more than 15 years researching Hawaiian monk seals. He has published over 52 peer reviewed articles, in addition t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Oceanic And Atmospheric Administration
The National Oceanic and Atmospheric Administration (NOAA ) is an American scientific and regulatory agency charged with Weather forecasting, forecasting weather, monitoring oceanic and atmospheric conditions, Hydrography, charting the seas, conducting deep-sea exploration, and managing fishing and protection of marine mammals and endangered species in the US exclusive economic zone. The agency is part of the United States Department of Commerce and is headquartered in Silver Spring, Maryland. History NOAA traces its history back to multiple agencies, some of which are among the earliest in the federal government: * United States Coast and Geodetic Survey, formed in 1807 * National Weather Service, Weather Bureau of the United States, formed in 1870 * United States Fish Commission, Bureau of Commercial Fisheries, formed in 1871 (research fleet only) * NOAA Commissioned Corps, Coast and Geodetic Survey Corps, formed in 1917 The most direct predecessor of NOAA was the Enviro ...

Australian Fur Seal
The brown fur seal (''Arctocephalus pusillus''), also known as the Cape fur seal, and Afro-Australian fur seal, is a species of fur seal. Description The brown fur seal is the largest and most robust member of the fur seals. It has a large and broad head with a pointed snout that may be flat or turned up slightly. They have external ear flaps ('' pinnae'') and their whiskers ('' vibrissae'') are long, possibly growing back past the pinnae, especially in adult males. The fore- flippers are covered with sparse hairs over about three-quarters of their length. The hind-flippers are short relative to the large body, with short, fleshy tips on the digits. The size and weight of the brown fur seal depends on the subspecies; the Southern African subspecies is, on average, slightly larger than the Australian subspecies. Males of the African subspecies (''A. p. pusillus'') are in length on average and weigh . Females are smaller, averaging in length and typically weighing . Males of t ...

Hawaiian Monk Seal
The Hawaiian monk seal (''Neomonachus schauinslandi'') is an endangered species of earless seal in the family Phocidae that is endemic to the Hawaiian Islands. The Hawaiian monk seal is one of two extant monk seal species; the other is the Mediterranean monk seal. A third species, the Caribbean monk seal, is extinct. The Hawaiian monk seal is the only seal native to Hawaii, and, along with the Hawaiian hoary bat, is one of only two mammals endemic to the islands. ''N. schauinslandi'' is a conservation reliant endangered species. The small population of about 1,400 individuals is threatened by human encroachment, very low levels of genetic variation, entanglement in fishing nets, marine debris, disease, and past commercial hunting for skins. There are many methods of conservation biology when it comes to endangered species; translocation, captive care, habitat cleanup, and educating the public about the Hawaiian monk seal are some of the methods that can be employed. ...

Persistent Organic Pollutant
Persistent organic pollutants (POPs) are organic compounds that are resistant to degradation through chemical, biological, and photolytic processes. They are toxic and adversely affect human health and the environment around the world. Because they can be transported by wind and water, most POPs generated in one country can and do affect people and wildlife far from where they are used and released. The effect of POPs on human and environmental health was discussed, with intention to eliminate or severely restrict their production, by the international community at the Stockholm Convention on Persistent Organic Pollutants in 2001. Most POPs are pesticides or insecticides, and some are also solvents, pharmaceuticals, and industrial chemicals. Although some POPs arise naturally (e.g. from volcanoes), most are man-made. The "dirty dozen" POPs identified by the Stockholm Convention include aldrin, chlordane, dieldrin, endrin, heptachlor, HCB, mirex, toxaphene, PCBs, DDT ...

Monk Seal
Monk seals are earless seals of the tribe Monachini. They are the only earless seals found in tropical climates. The two genera of monk seals, ''Monachus'' and ''Neomonachus'', comprise three species: the Mediterranean monk seal, ''Monachus monachus''; the Hawaiian monk seal, ''Neomonachus schauinslandi''; and the Caribbean monk seal, ''Neomonachus tropicalis'', which became extinct in the 20th century. The two surviving species are now rare and in imminent danger of extinction. All three monk seal species were classified in genus ''Monachus'' until 2014, when the Caribbean and Hawaiian species were placed into a new genus, ''Neomonachus''. Monk seals have a slender body and are agile. They have a broad, flat snout with nostrils on the top. Monk seals are polygynous, and group together in harems. They feed mainly on bony fish and cephalopods, but they are opportunistic. The skin is covered in small hairs, which are generally black in males and brown or dark gray in females. Monk ...

Penguin Bank
Penguin Bank is the name given to a now-submerged shield volcano of the Hawaiian Islands. Its coral-capped remains lie immediately west of the island of Molokai, under relatively shallow water (see bathymetric map at the right). Geology The Penguin Bank volcano is part of the Hawaiian-Emperor seamount chain. It was one of the seven principal Cenozoic Era volcanoes that formerly constituted the prehistoric island of Maui Nui, along with West Molokai, East Molokai, Lānai, West Maui, East Maui, and Kahoolawe. The date of the last eruption is unknown, but shield-building eruptions likely ended entirely 2 million years ago with no evidence of a rejuvenated stage. This volcano like all other volcanoes of the Hawaiian-Emperor Seamount Chain would have formed in a series of stages such as Pre-Sheild, Sheild-building/Subaerial, and Post-Sheild that was divided into two rift-zones broken by a summit caldera. This volcano could have stood roughly 4,000 to 7,000 feet above sea level. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Animal
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) IUCN Red List, Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have Environmental law, laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct.
