BOG
all of the froth and algae make bogs wet spongy and acidic
bogs are one of the only places that can actually grow cranberries
animals that can live in acidic environments like turtles lizards and frogs
there are lots of algae and pitcher plants
too much human interference

coastal ecosystem
COASTAL ECOSYSTEMS
By:Luis Huicochea
Beaches
A beach is defined as an accumulation of sediment-usually sand or gravel-that occupies a portion of the coast. The active beach, the area
of loose sediment subject to transport by wind, waves, and currents, is divided into three regions: the backshore, the foreshore, and the
offshore. The active beach is backed by the coastal upland, which can be a dune, a cliff, a soil embankment, a fossil berm, or an
engineering structure such as a seawall or a revetment. Healthy beaches are in a state of dynamic equilibrium, where the net influx of
sediment-or sources, equals the net loss of sediment-or sinks. Sources of beach sediment include skeletal material from coral reef
ecosystems, onshore transport of sand, longshore transport, headland erosion, volcanic glass, river input, and erosion (scarping) of the
coastal upland.
To steward coastal water bodies and their tributary watersheds by improving the quality, quantity, timing and distribution of surface and groundwater inflows
by providing leadership in engineering, science and planning with both public and private partners.
Coastal Ecosystems encompasses seven major ecosystems. Each ecosystem, informally named by the coastal water body in which it resides, possesses unique
hydrologic, biologic and anthropogenic features and includes both land (watershed) and water (estuary, lagoon, river, etc.) components. The ecosystems are: St.
Lucie Estuary / Indian River Lagoon, Loxahatchee River, Lake Worth Lagoon, Biscayne Bay, Florida Keys, Estero Bay and Caloosahatchee Estuary.
We have used ecological network analysis to compare nitrogen cycles from five well-researched coastal ecosystems. These included a
representative ricefield and two lagoons (Tancada and Encanysada lagoons) in the Ebro River delta, Spain; a region of the Sacca di Goro,
a lagoon at the mouth of the Po River, Italy; and a drowned river estuary in North Carolina, USA, the Neuse River estuary. We
constructed networks for the various systems and ranked them by trophic status (i.e., degree of eutrophication) using four indices. We
then considered the importance of (1) trophic status, (2) growth form of dominant primary producer and (3) water residence time to the
intensity and pattern of recycling and to the manner in which the systems can “filter” N. Three indices of flux (rate of import, primary
producivity and total systems throughput) gave similar rankings of trophic status among ecosystems with the Italian and U.S. systems
being most eutrophic, ricefields next, and then the two Spanish lagoons. Patterns of N export and of cycling within the systems were
most closely related to the growth form of dominant primary producers. Phytoplankton, with their rapid turnover rate, foster rapid
recycling within the water column and continuous transfer to sediments and export. Submersed and emergent aquatic vegetation and
macroalgae create lags and pulses within systems by sequestering N during growth and releasing it during senescence, death and
decomposition. Trends in cycling among systems relative to trophic status or water residence appear largely secondary to primary
producer growth form.

Everglades
~The Everglades are subtropical wetlands that are damp and flat.
~A unique thing of the Everglades is that it’s the only place in America where you
can find both crocodiles and A!igators in the same place.
~Producers that live in the Everglades are sawgrass, Mangrove trees, ink wood
and poison wood trees.
~Consumers in the Everglades are the American A!igator, the Great blue Heron,
the coral snake, and the diamondback snake.
~Threats to the Everglades are Water control, introduced species that threaten
habitats in the communities (ex-Juvenile Mayan Cichlid), and development
which has destroyed more then half of the original everglades.

Saltwater Marsh
Ecosystem
By: Shelby Bo
These salt water marshes are a great
habitat for birds and other wildlife.
They usually occur on level tideinfluenced areas. Unlike other marshes
these marshes are made unique by their
salt water contents. Vegetation consists
of grasses and woody plants. 90% of
the vegetation population is made up of
trees and woody plants such as bushy
seaoxeye, mangroves, cabbage palm,
bigleaf leaf sumweed, matrimony vine,
and lyonia species. The prime
consumers of these plants are are
otters and gulls. 350 years of wetland
destruction hand pollution have left a
lasting legacy on the saltwater marshes.

Freshwater lakes
Lakes are bodies of water surrounded by land and are not part of the ocean. They are generally found in
mountainous areas.Many animals drink and use the lake to survive out in the wild.What makes this
ecosystem unique is that most fresh water lakes can be used for many reasons. People can use this as
drinkable water,watering plants, and animals can use it as well.There are many producers in lakes and one of
the biggest one is trout. The the trout consume 90,000 frogs, that must consume 27 million grasshoppers that live off of
1,000 tons of grass.Some consumers are snails, frogs, and fish.Some threats are pollution and diversion of water for agriculture
and industry are destroying the freshwater lakes and rivers.

MARINE
Marine is the study of organisms in the ocean.
-The general characteristics of my ecosystem is that there habitats are mostly tide pools, coral reefs,
and kelp forests.
-What makes my ecosystem unique is that Marine is a good resource, providing food, medicine, and
raw materials.
-The Primary Producers in my ecosystem are phytoplankton categorized into cyanobacteria, also
various types of algae. Fish larvae is also a primary consumer having starfish (Right) in the two
types of fish involving larvae.
-The primary consumers in this ecosystem are krill, mollusks, and fish
-The greatest threats to my ecosystem are human activity and and other environmental realms.

Estuary
Brown and green are the general
colors of this area.This is where the
river meets the sea in shallow,
protected bays.
Plankton are primary producers in
this ecosystem
Jelly fish are the primary consumers
The picture shows new
development that is negatively
affecting the Estuary.

Swamp
A Swamp has open surface water. They are associated with lakes, rivers and waterways. They are not as wet as
marshes or fens, however they still hold a significant amount of water during dry seasons.Swamps are nutrient
rich and productive.
This is a unique ecosystem because it is mostly home to and is dominated by trees and woody vegetation.
It has poor drainage, causing water to be stationary for years when it gets caught in a swamp.
Primary producers in this ecosystem are trees, floating plants such as duckweed, algae, and cyanobacteria.
Some primary consumers are detrivores, water snails, and aquatic worms.
Some threats to this ecosystem is that people are building dams, reducing the area that these swamps cover.
Scarcity of reeds, vegetation change, lowered water table and reduced access to drinking
water are some of the problems arise as a result of drainage and cultivation of swamps

River Ecosy!em
By D"glas VanOo!
•River
ecosystems which are waterways that
lead into oceans
•They are unique because they are always
important to where they are
•Plankton is one of the many producers of a
river ecosystem
•The Smallmouth Buffalo (fish) is a primary
consumer of this ecosystem
•Humans are threats to river ecosystem
through pollution

Freshwater Marsh
-Are often found in open areas near rivers and lakes.
-Usually 1 to 6 feet deep and is rich in minerals.
-Water flows into marshes from rain and other sources like
streams and creeks.
-It is unique because a lot of animals live there and a lot
of plants grow there.
-The primary producers are;any kind of plants such as
cattail, swamp milkweed, and common sulphur.
-The primary consumers are; European earwig, Cottontail
Rabbits, and Monarch.
-The greatest threats to the Freshwater Marsh are climate
change and water level rising.
