Question 1: Biodiversity and Ecosystem Health (20 points) a) Describe two ways of measuring biodiversity. Explain the relationsh

ip between biodiversity and ecosystem stability. As part of your explanation, discuss how susceptibility to disease in agricultural crops and in isolated tribal human populations provides evidence that supports this idea. (5 points)

Answer:

explanation below

Explanation:

A) Biodiversity is simply known as the number and variety of organisms found in a definite environment or region.  Scientists have devised several ways of measuring biodiversity and the methods to be used depend on the type of organisms they are to count.  

Canopy fogging – one of the ways of measuring biodiversity, has remained an effective way of obtaining details about the biodiversity of insects.  It involves the act of spraying  low dose of insecticides on a tree top, and when the insects fall from the trees, they are being collected on a large screen, that looks like a funnel.  

Transact sampling is another way of measuring biodiversity and this time, with a transact line. The transact line is usually a measuring tape or rope that has been marked at set intervals.

b) Ecosystem stability is the ability of the ecosystem to maintain its steady state, even after it has experienced stress or disturbances.  The biodiversity of an environment makes huge impact on the ecosystem stability in that particular area. It has been known that certain areas that have high levels of species and genetic diversity, are more likely going to an ecosystem that is complex, with varying food webs and biotic interactions. The increase in this complexity makes it more likely that the ecosystem of that area will rightly move back to a stable state whenever disturbances are experienced.

There are evaluated scientific evidence that shows that reduced biodiversity affects the transmission of communicable disease in agricultural crops, animals and humans. Loss of biodiversity usually increases susceptibility to diseases in plants and humans.

Scientific research about the carbon cycle and global warming would be most valuable if the results
GarryVolchara [31]

Answer:

if the results are efficient in answering the problems raised in the research and if they manage to come to terms with the hypotheses.

Explanation:

As you may know, scientific research must be done through several steps that allow an experiment to be carried out in order to reach conclusions on a certain topic.

In research on the carbon cycle and global warming, it is necessary for the researcher to raise problems and questions about this topic, as well as to raise hypotheses that must be directly related to the results of the experiment. If the result of the experiment is efficient in answering the research problems and questions, in addition to being able to agree with the presented hypotheses, it means that the research has value within the scientific branch in which it fits, in addition to showing that the experiment was done correctly.

Why might a phylogeny based only on molecular data show a different pattern of relationships than a phylogeny of the same taxa b
Kitty [74]

A phylogeny of the same taxa based only on morphological traits:

Some highly conserved genetic sequences can result in unrelated species appearing closely related in a molecular phylogeny, and not reflect the same pattern as the morphologic phylogeny.

Gene sequence changes may not result in morphological changes.

Gene sequences always provide more data than morphological traits.

Morphological analyses always provide more data because each morphological trait is the result of the expression of many genes.

The molecular data may be based on the analysis of introns, which aren't expressed and don't contribute to the evolutionary history of a group of taxa.

Why is molecular data more accurate?

Phylogenetic trees reconstructed from molecular sequences are often considered more reliable than those reconstructed from morphological characters, in part because convergent evolution, which confounds phylogenetic reconstruction, is believed to be rarer for molecular sequences than for morphologies

How do different biomes increase earth's biodiversity?
galben [10]

Answer:

Since Biodiversity means variety of living species on earth, different biomes provide habitats for those species. If there was no biomes then they would be no biodiversity. So the impact of biomes provide a living nature for those animals.
