Florida Current: the segment of current between the Gulf of Mexico Loop Current and the Gulf Stream form the Dry Tortugas to the southeastern tip of Florida, and confined by the 250 meter and 500 meter isobaths. Southwest Florida Estuaries Prepared for: Tampa Bay Estuary Program Sarasota Bay Estuary Program Charlotte Harbor National Estuary Program Prepared by: Janicki Environmental, Inc. St. Petersburg, Florida 14 July 2010 . Other bird species include Bald eagles, seagulls, pelicans, sandpipers, cormorants, ospreys, and flamingos. The fertilized eggs develop into larvae and are transported to estuaries and bays by currents and tides. The estuary contains 5 State Parks, 4 National Wildlife Refuges, a National Seashore, an Intracoastal Waterway, a Navy Submarine Base, a Space Force Base, and a National Space Center. The Florida Museum is open! Estuaries — where fresh and salt water mix — are important habitats for a variety of sea life. Sea grass leaves provide protective cover for juvenile marine animals and provide food for other animals, such as the manatee. The majority of recreationally and commercially caught fish, crustaceans, and shellfish spend at least part of their lives in these estuaries.

Estuarine and marine habitats provide habitat and nesting areas for many birds. Hermit crabs (Pagurus spp.) Photo © Gerald and Buff Corsi, California Academy of Sciences. Shallow waters of Florida Bay offer protection to juvenile fish from open water predators. Invasive plants are usually non-native, but sometimes native plants can have invasive tendencies. Photo courtesy U.S. Widgeon grass (Ruppia maritima) also prefers waters of low salinities. In the estuary, there is little precipitation throughout the year. Native vegetation on Sanibel Island is world-class, including the sea grape, sea oats, mangroves, and a variety of palm species. Flora changes from macroalgae in fresh and brackish waters to seagrass and mangroves as salinity increases. brackish: somewhat salty, containing salt, where freshwater mixes with saltwater. … Mangrove forests and islands are also common along the shoreline and just offshore in estuarine waters.

The Everglades sheet flow of water eventually drains into the Florida Bay to the south and the Gulf of Mexico to the southwest. Photo courtesy U.S. Geological Survey, Common merganser (Mergus merganser). Extensive seagrass meadows within Florida Bay serve as important habitat for a variety of species including invertebrates such as the pink shrimp (Penaeus duorarum) and spiny lobster (Panulirus argus). salinity: concentration of total salts dissolved in water, usually measured in parts per thousand. Many commercially and recreationally important fish reside in Florida Bay during at least part of their life history, migrating offshore to spawn. Over 500 species of fish reside in waters off south Florida’s shoreline while over twice as many fish species live in the waters of the Gulf of Mexico and the Florida Current. The sea anemones benefits from the clown fish by getting food, and clown fish benefit from sea anemones by getting protection from prey. and stone crabs (Menippe mercenaria) also live within the seagrass flats while fiddler crabs (Uca spp. Extensive seagrass meadows within Florida Bay serve as important habitat for a variety of species including invertebrates such as the pink shrimp (Penaeus duorarum) and spiny lobster (Panulirus argus). Commercially important species including shrimp and lobsters reside inhabit estuarine waters. Photo © Tobey Curtis, West Indian manatee (Trichechus manatus). As salinities increase, Acetabularia crenulata, Caulerpa verticillata, and Udotea wilsoni become the dominant macroalgae along with shoal grass replacing widgeon grass. Animals can hide from predators in marsh vegetation, because the shallow brackish area physically excludes larger fish. https://www.floridamuseum.ufl.edu/southflorida/habitats/estuarine-marine tropical: tropical zone lies between 23.5 degrees north and south of the equator, has small seasonal changes in temperature and large seasonal changes in precipitation. Activities in Indian River Lagoon. Hermit crabs (Pagurus spp.) However, this flow of freshwater has greatly decreased over the past century due to the construction of a series of canals in the Everglades. There are oyster reefs where oysters, mud crabs, and small fish may be found. Photo courtesy South Florida Water Management District, Red-breasted merganser (Mergus serrator). Estuaries have complex ecosystems. Freshwater also enters the bay through rainfall, surface run-off, and groundwater. Florida East Coast's Indian River Lagoon National Estuary merges the freshwater of 5 rivers, and the saltwater of 4 ocean inlets, to form the Mosquito, Banana River, and Indian River Lagoons. Photo courtesy NOAA, Green-backed heron (Butorides striatus). Hardbottom habitats provide important cover and feeding areas for many fish and invertebrates. Habitat – one could also say "home" – includes shellfish beds, sea grass meadows, salt and fresh marshes, forested wetlands, beaches, river deltas, and rocky shores. In recent years, the waters of Florida Bay have been hypersaline with salinities reaching over 35 parts per thousand (ppt). Photo courtesy U.S. The dividing line separating the Gulf of Mexico and Florida Bay runs from Long Key northwest to Cape Sable. Many of Florida's popular marine fisheries species spend the early part of their lives protected in salt marshes. https://www.floridamuseum.ufl.edu/southflorida/regions/florida-bay temperate: temperate zone lies between 30 and 60 degrees latitude, climate undergoes seasonal changes in temperature and moisture. Florida Shellfish Estuaries—Characteristics Florida’s coastline measures 2173 km along the Gulf and Atlanticcoastalplains(Ningetal.2003)andwithinthatcoast-line, coastal geomorphic characteristics include barrier islands, wetlands, and embayments that provide a diversity of estuarine environments that support shellfish aquaculture. hypersaline: Water with excessive or supersaturated salt content.

The prevailing climate in an Estuary biomeis referred to as a local steppe climate. ), isopods, and barnacles (Balanus balanoides) reside in the intertidal zones. Gamefish that are commonly found in the marine and estuarine waters of the Everglades include both tropical and temperate species. Fish, shellfish, and migratory birds are just a few of the animals that can live in an estuary. This biome includes several examples of mutualism, commensalism, parasitism, competition, and predation. Estuaries — where fresh and salt water mix — are important habitats for a variety of sea life. South Florida is the only location worldwide where crocodiles and alligators coexist. Supplementary material. Estuaries are often called the “nurseries of the sea” because so many marine animals reproduce and spend the early part of their lives there. Six species of sea grasses live in Florida's estuaries.

The richness in species diversity is due to the mixing of tropical and temperate species throughout this region as well as the varied marine environments including reefs, estuaries, mangroves, seagrass beds, and bays. Exotic species are non-native, but do not necessarily harm native habitats. Sanibel Island’s marshlands, estuaries, mangroves and beaches are teaming with life, including many species of birds including flamingos and rosette spoonbills, the American alligator, manatees and many other animals. Shoal grass. The term estuary is derived from the Latin words aestus (“the tide”) and aestuo (“boil”), Photo © Laurel Canty-Ehrlich, NOAA, Raccoon (Procyon lotor). Florida Bay is the largest body of water within the Everglades National Park, covering more than 1,100 square miles (2,850 square km) between the southern tip of Florida and the Florida Keys. Although Florida's estuaries 'come in many shapes and sizes, all of them share some environmental features. Photo courtesy South Florida Water Management District, Goliath Grouper (Epinephelus itajara). Consisting of a series of shallow water basins, the bay is located on a shallow shelf where freshwater flowing from the Everglades mixes with salt water from the Gulf of Mexico. The Florida Department of Environmental Protection is the state’s lead agency for environmental management and stewardship – protecting our air, water and land. Sea grasses are of vital importance to the estuary as habitat, filtering system, oxygen producer and bottom stabilizer. 12237_2019_600_MOESM1_ESM.eps (37 kb) Figure A1 Tracks of two … Photo © Marguerite Gregory, California Academy of Sciences, Black-necked stilt (Himantopus mexicanus).

Estuaries and coastal waters provide essential habitat for over 75 percent of the commercial fish catch and 80 … Where Florida rivers empty into the Atlantic Ocean and Gulf of Mexico, productive ecosystems called estuaries thrive. IACUC-16-022 from the Institutional Animal Care and Use Committee of Florida International University and in accordance with sampling permit no. Distinguishing characteristics of the crocodile include a pointed snout and grayish-green coloration while the alligator has a rounded snout and black in color. The mangroves' crescent-shaped roots arch alongside our kayaks; the roots offer protection for small animals and for the young of coastal and ocean species that use the lagoon as a nursery. Invasive species can cause harm to native plant or animal populations, the economy, or human health because they grow and spread rapidly. These communities generally have low diversity and are dominated by octocorals, algae, sponges, and a few stony coral species. Photo courtesy U.S. Geological Survey, American bittern (Botaurus lentiginosus). The freshwater habitats of the Everglades are dominated by marsh and slough flora, however the flora changes moving downstream where the freshwater mixes with seawater. Within Florida Bay, there are limited areas of hardbottom reef. The shoreline along Florida Bay supports mangrove forests with nearshore waters dotted with hundreds of mangrove islands. The vision of the Florida Department of Environmental Protection is to create strong community partnerships, safeguard Florida’s natural resources and enhance its ecosystems. Bottlenose dolphins (Turiops truncatus) and the West Indian manatee (Trichechus manatus) are common in the waters of Florida Bay.

Dolphins and manatees reside in the waters of Florida Bay. EVER-2017-SCI-0031 granted by Everglades National Park. Fresh surface water enters the bay via sheet flow and direct flow from Taylor Slough from the southern portion of the Everglades into Whitewater Bay. The Gulf of Mexico includes the westernmost coastal waters of the Everglades National Park. Its rain season falls between April and October, a… The American alligator Alligator mississippiensis) is considered a threatened species due to its similarity to the American crocodile. diversity: refers to the variety of species within a given association, areas of high diversity are characterized by a great variety of species. Manatee. The estuaries of Southwest Florida provide vital habitat to many threatened and endangered species including loggerhead sea turtles, manatees, least terns, and a variety of insects, crustaceans, birds and small mammals. This steppe climate is a kind of climate that is normally experienced in the middle of continents or in the leeward side of high mountains. Masks are required at all times.

Past the intertidal zone, turtle grass (Thalassia testudinum) becomes the dominant seagrass, forming extensive meadows that provide habitat and shelter for a diversity of marine organisms. The Chesapeake Bay, as one example, includes several different habitats. This habitat is home to wading and probing shorebirds, oceanic birds, and diving birds. National Estuarine Research Reserve System Estuary Education. Where rivers and streams meet the sea, a unique habitat is formed. The decaying plants are eaten by microorganisms (animals so tiny you need a microscope to see them.) The seagrasses, mangroves, and shallow waters offer protection from open water predators. In these drainage areas, freshwater and seawater mix, creating brackish water estuaries. The bottom of the bay includes extensive seagrass beds and hardbottom reef habitat. South Florida’s coastal estuaries are among the most threatened natural environments in the state. Learn what else we are doing to keep you safe. The roseate spoonbill (Ajaia ajaja), reddish egret (Egretta refescens), double-crested cormorant (Phalacrocorax auritus), and black-crowned night heron (Botaurus lentiginosus) are all known to nest within the habitats surrounding Florida Bay. This mixing of saltwater and freshwater results in a salinity gradient across the entire bay, with salinities increasing from the north to the south. Photo courtesy South Florida Water Management District, Oyster bed. Fish and Wildlife Service, Glossy ibis (Plegadis falcinellus). An example of each is listed below: An example of mutualism is clown fish and sea anemones. Photo courtesy South Florida Water Management District, Turtle grass. The animals that live here must be adaptable and able to tolerate extreme heat and cold as well as floods, which bring more freshwater, and droughts, which bring an increase in salinity. As the tide rises and falls, water depth and chemistry change, creating a wide range of habitats.
