Unit 8 BIG 4

Sarasota bay

Human impact- wastewater from humans run off into the Sarasota Bay causing an excessive of nitrogen pollution

environmental impact- the excess nitrogen causes algae to grow that chokes the environemnt of oxygen

Economic impact- people uses the estuarie to fish and then in turn sell the fish for money

Goveverment impact- the government has passed laws to protect some animals in the Sarasota Bay such as the loggerhead turtle

Zoo Blog

Prompt 2

Entertainment- The FW zoo strives to entertain their guests. The entire time I was there I had a blast, the animals were awesome. The zoo definitely fulfilled their commitment because I was never bored while I was there, A change they could make is install electrical shockers in all of the environments and if the animals fall asleep they are mildly shocked to keep them awake, this will ensure the animals are always active and entertaining the guests.

Famine discussion

-some countries are much more wealthier than others so in turn can produce their own food more efficiently and/or but it from another country.

-communist government

-I do not believe that because there is no evident to support it

-we should share more with less fortunate countries

-we need to be award and if we're aware we would be more aware

-all of my group members complained about rationing and equallity because America is the needy

-we need to be more resourceful because if we're more resourceful we would be more resourceful dawg

1. Igneous rock - formed when the tectonic plates are pushed together and compress the magma used to make it. 

Sedimentary rock- formed when the tectonic plates grind against each other 

Metamorphic rock- formed when the tectonic plates are beaten together 

2. Physical weathering can be rain wearing down and rock formation and chemical weathering can be when rocks oxide and can decide how a rock is. 

3. Sand, silt, and clay. The soil's permeability and water retention is decided by what makes up the soil because all three of those things have different water retention 

Hot Spot

Cerrado

1. Location of the hotspot and type of ecosystems found there.

                  South America, Savanna                 

2. Describe at least one endemic plant species and one animal species found there

                 Caryocar brasiliense, blue-eyed ground-dove

3. Describe the socio-economic conditions  (pre-industrial, transitional, industrial, post-industrial)

                   Around 67 percent of the Cerrado ecoregion has been already either completely converted or modified in a major way. In contrast, only 1 percent of the total area of the Cerrado Region is protected in parks or reserves. Most of the large-scale human modification in the Cerrado took place in the last 50 years. With a construction of a new capital of Brazil (Brasília), several highways were built, opening the region to a large process of development. During the 1970's and 1980's, several investment programs financed by multilateral funding agencies together with generous government subsides transformed the Cerrado in a new agricultural frontier. Managed pastures and large-scale plantations of soybeans, corn, and irrigated rice were established. As a result, thousands and thousands of square kilometers of cerrado were removed without any studies on environmental impacts.

4. Human induced and/or natural reasons why species biodiversity is decreasing in that region

                   The biodiversity of cerrado is extraordinary. For instance, for only three orders of insects (Lepidoptera, Hymenoptera, and Isoptera) scientists have recorded 14,425 species, representing at least 47 percent of the species of those orders in Brazil. Biodiversity of cerrado is comprised by at least 10,400 species of vascular plants, 780 of fishes, 180 of reptiles, 113 of amphibians, 837 of birds and 195 of mammals. Most of these species are restricted to cerrado. The percentage of endemic species varies among taxonomic groups, from 4 percent in birds to 50 percent in vascular plants. Cerrado is also a unique evolutionary theater where species from the largest [[South America]n forests (Amazon and Atlantic Forest) and from the largest South American dry habitats (Chaco and Caatinga) intertwine.  Humans are destorying habits to make roads which is causing biodiversity to decrease

1. What is being done to protect this hotspot

The cerrado shrublands represent the largest ecoregion in the Americas, and extend across much of eastern Brazil, and intoParaguay and Bolivia. This ecoregion is host to a number of endemic species. For the Brazilian portion, out linework follows INEGI classifications, from which we lumped the following vegetation types: "open forest cerrado", "dense forest cerrado", "park cerrado", "woody-grass (Gramineae) cerrado", "savanna-seasonal forest transition", and all "secondary vegetation" and "agricultural activities" encompassed by this broader classification. In Bolivia we followed the Ribera et al. classification of "cerrado savanna" and subsequent linework. In Paraguay we referred to UNESCO, who classify this as "medium-tall grassland with broad-leaved evergreen tree synusia (cerrado)". 

6. Any interesting information you found about the area  

                 The animals were really cool and the plants were pretty neat

 

FRQ

Extinction of  a species cam greatly impact the world has a whole. Every species in this world play an important part, and when that part suddenly goes missing the mechanics of an environment can become disrupted. Humans are creating great negative impacts on environments world wide, and in turn actually causing species to go extinct. Habitat destruction, over harvesting, and emerging diseases are all factors that greatly contribute to the extinction of species. Extinction can have a huge environmental impact. Every environment has a complex food web that consists of all the animals in an ecosystem. All the animals are connected to each other and affect each other. When one animal is taken out of that food web because of extinction, all the animals in that ecosystem must find a filler for the empty stop. The economy is a big reason why animals go extinct. Over hunting of an animal because they are valuable can cause many to decrease in population size because they get killed faster than they can repopulate. For example white rhino in Africa are being killed into extinction for their white horns. The governments around the the world are trying to put a stop to the extinction of animals through polices they pass that can put endangered animals into protection.

1. Ecosystem Diversity - the variety of different types of ecosystems

Species Diversity- The variety of different types of species within an ecosystem

Genetic Diversity- the variety of genes within a given species

*Genes form the blueprint of an organism's traits.  The diversity of traits ultimately helps determine the species diversity and ecosystem diversity on Earth.

2. Humans benefit from diversity from agricultural and medicinal. Organisms benefit from stability and genetic reserves.

3. Scientists organize species into categories that indicate how related they are to one another, these branching patterns are called phylogenies. The number of species on Earth range between 5 million and 100 million.  Most agree to an estimate around 10 million.

4. Because there are so many different types of climates and ecosystems

5.  To show the relationship among organisms and they also show patterns of evolution.  

6.  A gene is a physical location on the chromosomes within each cell of an organism and a genotype is the complete set of genes in an individual. 

7.  A random change in the genetic code produced by a mistake in the copying process or environmental factories such as UV exposure can also mutations.

8.  If it brings new combination of  genes that can produce novel traits, this can cause a mutation.

9.  Genotype is the complete set of genes of an individual changes in genotype due to the mutation or recombination can produce changes in an individual's phenotype.  Phenotypes are the actual set of traits expressed in that individual.  An individual's phenotype can be influenced by both the genotype and the environmental factors.

10.  A change in the genetic composition of a population over time as a result of the environment determining which individuals are most likely to survive and reproduce.  Some examples are dogs and agriculture .

11.  Not all offspring can survive 

Individuals differ in their traits

Individuals produce an excess of offspring

Differences in traits are associated with differences in the ability to survive and reproduce.

Differences in traits can be passed on from parents to offspring.

12.  Mutation - is a permanent change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal genetic element.

Genetic Drift - is the change in the frequency of a gene variant (allele) in a population due to random sampling

Bottle Neck Effect - is a sharp reduction in the size of a population due to environmental events (such as earthquakes, floods, fires, or droughts) or human activities (such as genocide).

Founder effect - is the loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population.

13.  Snapping shrimp off the Isthmus of Panama 

14.  Rate means that the species needs to evolve fast enough to survive.

15. Because it is used to being in a chronic lineage in its lifetime.  Racoon and Kola bear.

There are so many different kinds of plants and animals because they can change over time.

Evolution is when animals and plants change over time.

Something has evolved when it changes over time by adapting to its environment.

Yes anything can evolve however, it takes a period of hundred of years to evolve.
