Plant adaptations

  • seaweed, sea cabbage, kelp, algae, and plankton are found in the bottle nose dolphins environment
  • the plankton provides oxygen
  • these plants provide food for the animals to survive and a hiding place for animals to hide from their predators

Humans impact

  • industrial discarding and sewage are damaging bottle nose dolphins and their food source
  • pollution is toxicating their environment
  • boat traffick, habitat destruction and fisher mans are affecting their environment
  • fisherman are killing bottle nose dolphins because the bottle nose dolphins eat the same kind of fish that the fisher mans are fishing
  • fisher man are decreasing the food source for bottle nose dolphins
  • people feeding bottle nose dolphins makes the dolphins less able to search for food on their own
  • they also expect that all humans will feed them
  • have been caught by humans for meat, lather, oil and meal

  • the phosphorus cycle
  • is a limiting factor for the growth of plants
  • large amounts of phosphorus in an aquatic environment can cause problems
  • large amounts of phosphorus lead to algal blooms
  • these blooms impact wildlife population negatively

citations

  • the Oxygen cycle
  • they need it for cellular respiration
  • the hydrologic cycle
  • pathway of water on earth from the atmosphere, to the surface, below ground, and back to to the atmosphere
  • they need water that they hydrologic cycle provides them with
  • the nitrogen cycle
  • plants convert nitrates into amino acids and proteins
  • the carbon cycle
  • it has the essential components of carbohydrate, proteins, fats, and other organic molecules that make up a living organism
  • carbon flows from environment living organisms back to the environment

Cycling of Major nutrients

  • sharks are also found in their biome
  • many eat the abundant plankton
  • whales, dolphins, fish, purpoises are also found in their biome
  • surface seaweed is found in their biome

Power points i used to get information

  • use echolocation(technique) to find food and navigate.
  • technique use to find the location of objects by reflected sound
  • Their elongated upper and lower jaw helps them catch their food
  • the bottle nose help them to protect themselves from sharks
  • they have good eyesight
  • both above and under water
  • helps them protect themselves from predators and enemies
  • they never lose touch with their mother
  • they visit their mothers after they have separated

Community relationship

  • aggressive and friendly toward other animals
  • Bull sharks, tiger sharks, dusky sharks, great white sharks and killer whales eat bottle nose dolphins
  • although some of the sharks don't dare to attack a bottle nose dolphin because they are aggressive
  • feed on large varieties of fish , shrimp ,small rays and sharks
  • humans are their competitors because they compete for the same food

Bottle Nose Dolphin

Arda Map 10 million years ago

  • well adapted in the Belegaer ocean 10,000,000 years ago
  • Climate over the 10,000,000 million years increased in the water and the sea levels started to rise which increase the number of fish, sharks, whales, and other water animal
  • affected the predators, prey, etc by increasing their population
  • the water was getting warmer which meant more animals could survive, it also provided the animals more water to live in and move around and find their food source.
  • 8,000,000 years ago the ice in the Belegaer completely melted and the land bridges between Valimor and Beleriand is covered by ocean which became part of the Belegaer Ocean.
  • global warming was an environmental change that occur .
  • causes the ice to melt and caused the increase of water animals and other land animals
  • not all animals can survive in the cold mperature
  • like the bottlenose dolphin can die because of cold temperatures- they prefer warm climate

Scientific name: Tursiops truncatus

Males and females mature at different ages and varies on location

  • generally females mature at about 5-13 years and males mature at about 9-14

Maturity

  • This kind of dolphin survived because its on top of the food chain and their only predators are fisher mans , sharks and other bigger whales but because they adapted to the land they don't have to fear of many predators because most of their predators are at the land

Tursiop Landus

Tursiops landus

  • This kind of dolphin is able to survive for now because it is away from predators but soon they will be hunted them and they will become extinct because their prey is in the ocean and when they go to catch their prey, a shark can jump at them and eat them.
  • This type became extinct because they needed food so they had to return to the ocean to look for prey but when they returned the sharks attacked them and ate them, this led to many bottle nose dolphins being killed or died of hunger for not having a food source

Tursiops flyus

Timeline

  • they are mammals
  • helpful
  • can grow up to 2-4 meters long.
  • they are warm-blooded.
  • average dolphin's brain weighs about 1500-1600 grams.
  • consume between 17- 33 pounds food per day
  • have 80-100 teeth
  • swim 25miles/hr
  • playful and aggressive
  • can jump 20 feet

Background information

Tursiops flyus

Population relationship

  • female dolphins return to their mothers or other female relatives to raise their own calves
  • usually feed in a small group
  • work together to round up the classes of fish
  • swim in groups (called pods) of 10-25
  • larger groups of several hundred are called herds.
  • like to play
  • they ride the waves caused by boats or bigger animals like big whales
  • create bubble rings with their blowhole and spin bubble rings with their beaks and they break the bubble rings by biting them
  • learn this technique watching others do it
  • communicate with each others using chirps, whistles, and clicks.
  • create these sounds using nasal sacs their blowholes
  • each individual have a signature whistle
  • can be very aggressive but can also be social animals

  • males create a bond like an alliance with other males
  • Males and females mature at different ages and varies on location
  • generally females mature at about 5-13 years and males mature at about 9-14 years

Ecosystem relationship

  • can swim up to 1,794ft below the surface
  • they need air so they usually swim close to the surface
  • can stay up to 15 minutes under water
  • usually stay underwater for a few minutes
  • water temperatures of 10° to 32°C (50°-90° F).

Successional changes in ecosystem

  • changes in an ecosystem until it reaches the climax community
  • aquatic succession, begins in the shoreline and makes the water bodies smaller and more shallow
  • some aquatic plants grow where the water has gotten smaller
  • this plants help leave the soil wet but makes the bodies of water smaller
  • soon bushes are found where the bodies of water where at
  • then trees like the red maple trees are found
  • then other kinds of trees start to appear
  • the speed of succession depend of the size of body of water
  • the rate of succession is sped up by humans

Effects of successional changes

  • the environment loses water which will lead to many water animal dying
  • leads to less food for bigger water animals
  • many animals will be fighting for the same food
  • humans also fight for the same food like some fishes
  • animals habitats will be destroyed it water starts to get smaller
  • animals will move and look for another home

Diagram and cycling of major nutrients

Figure 1

  • spindle shape body
  • helps them swim fast
  • in case of danger they can swim as fast as 20 miles an hour
  • sleek and streamlined body
  • helps them swim quickly and easily
  • have gray to dark gray on their backs and white on the underside on its lower jaw and belly so they can camouflage in the environment and protect them from predators
  • ¨have a hypodermis (layer of fat and fibrous connective tissue) under the layer of the dermis
  • where extra calories are stored
  • prevents heat loss
  • have a physiology
  • helps them in adapt themselves while diving
  • while diving ,their heart rate slows down, helping them conserve oxygen.

Figure 2

Figure 2 shows how the energy flow.

  • As you can see of Figure 1, dolphins are on top of the food chain
  • but other bigger animals feed on bottle nose dolphins like some sharks
  • eat mainly fish and squid
