Susan Williams (marine Biologist)
Susan Lynn Williams (June 21, 1951 – April 24, 2018) was an American marine biologist and Distinguished Professor of Evolution and Ecology at the University of California, Davis, where she directed the Bodega Marine Laboratory from 2000-2010. She researched marine coastal ecosystems (in particular seagrass, seaweed, and coral reef habitats) and how they are affected by human activities. She was a strong advocate for environmental protection, credited with helping pass legislation expanding the boundaries of Northern California's Gulf of the Farallones and Cordell Bank national sanctuaries, increasing the area of federally-protected coastal waters. Early life and education Williams attended the University of Michigan, where she earned a bachelor's of science degree in biology in 1972. She then earned a master's degree in biological oceanography from the University of Alaska in 1977 and a doctoral degree in botany and marine biology from the University of Maryland in 1981.

Ecosystems
An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. Interna ...

Hasanuddin University
Hasanuddin University ( id, Universitas Hasanuddin) which is abbreviated as Unhas, is one of the largest autonomous universities in Indonesia. It is located in Makassar, South Sulawesi, Indonesia. Unhas was established on September 10, 1956, and named after Sultan Hasanuddin, a former King of the Gowa Kingdom. History Hasanuddin University's history was begun at Makassar in 1947 as part of the Faculty of Economics of University of Indonesia based on the Decree of the Lieutenant General Governor of the Netherlands East Indies Government Number 127 dated July 23, 1947, which during the early years of its establishment had faculties scattered across the archipelago. Due to uncertainty and chaos in Makassar and its surroundings, the faculty who previously led by L.A. Enthoven as director was suspended and then reopened again as branch of the Faculty of Economics of University of Indonesia on October 7, under the leadership of G.H.M. Riekerk. This faculty was the beginning of Hasanudd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangrove
A mangrove is a shrub or tree that grows in coastal saline water, saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are ad ...

Coral Reefs
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of Colony (biology), colonies of coral polyp (zoology), polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the Class (biology), class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fis ...

Biodiversity Hotspot
A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. Norman Myers wrote about the concept in two articles in ''The Environmentalist'' in 1988 and 1990, after which the concept was revised following thorough analysis by Myers and others into “Hotspots: Earth’s Biologically Richest and Most Endangered Terrestrial Ecoregions” and a paper published in the journal ''Nature'', both in 2000. To qualify as a biodiversity hotspot on Myers' 2000 edition of the hotspot map, a region must meet two strict criteria: it must contain at least 1,500 species of vascular plants (more than 0.5% of the world's total) as endemics, and it has to have lost at least 70% of its primary vegetation. Globally, 36 zones qualify under this definition. These sites support nearly 60% of the world's plant, bird, mammal, reptile, and amphibian species, with a high share of those species as endemics. Some of these hotspots support up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral Triangle
The Coral Triangle (CT) is a roughly triangular area in the tropical waters around the Philippines, Indonesia, Malaysia, Papua New Guinea, the Solomon Islands and Timor-Leste. This area contains at least 500 species of reef-building corals in each ecoregion.Veron et al. Unpublished data The Coral Triangle is located between the Pacific and Indian oceans and encompasses portions of two biogeographic regions: the Indonesian-Philippines Region, and the Far Southwestern Pacific Region.Veron, J.E.N. 1995.

Seagrass
Seagrasses are the only flowering plants which grow in marine environments. There are about 60 species of fully marine seagrasses which belong to four families (Posidoniaceae, Zosteraceae, Hydrocharitaceae and Cymodoceaceae), all in the order Alismatales (in the clade of monocotyledons). Seagrasses evolved from terrestrial plants which recolonised the ocean 70 to 100 million years ago. The name ''seagrass'' stems from the many species with long and narrow leaves, which grow by rhizome extension and often spread across large "meadows" resembling grassland; many species superficially resemble terrestrial grasses of the family Poaceae. Like all autotrophic plants, seagrasses photosynthesize, in the submerged photic zone, and most occur in shallow and sheltered coastal waters anchored in sand or mud bottoms. Most species undergo submarine pollination and complete their life cycle underwater. While it was previously believed this pollination was carried out without pollinators ...

Coastal And Estuarine Research Federation
The Coastal and Estuarine Research Federation (CERF) is a private, nonprofit organization that was created in 1971. At that time, the members of two regionally based organizations, the Atlantic Estuarine Research Society (AERS) and the New England Estuarine Research Society (NEERS) recognized the need for a third estuarine organization that would address national (now worldwide) estuarine and coastal issues. Today, CERF is a multidisciplinary federation of members and seven regionally based affiliate societies dedicated to the understanding and wise stewardship of estuaries and coasts worldwide. Mission CERF advances understanding and wise stewardship of estuarine and coastal ecosystems worldwide. Its mission is to: https://www.cerf.science/about-us *Promote research in estuarine and coastal ecosystems *Support education of scientists, decision-makers and the public *Facilitate communication among these groups Membership in CERF is open to all who support these goals.
