i actually asked my ecology lecturer this myself actually.
his reply was something along the lines of, if the species is believed to be indangered, people wont try to remove them for analysis, and will try to desterb them as little as possible. as a general rule of thumb though, any ecological survey should be carried out with as little disruption as possible, not just to ensure as little damage is done to the species as possible, but also so that you can be sure that all your observations are valid, and not because you've desturbed them.
Scientists collecting species they are studying can have both positive and negative impacts on the environment. On one hand, it can help in conservation efforts by providing valuable information about the species, their habitats, and threats they face. On the other hand, excessive collection can disrupt ecosystems and harm populations, especially if not done ethically or sustainably. Thus, it is crucial for scientists to follow ethical guidelines and regulations to minimize any negative impact.
because then scientists can collect more data on that species
It impacts it because they mostly take so much that the species may turn extinct.
organism
A collecting net often is used by scientists to collect insects. It is a good tool to use for those who are trying to find different species for research and other uses.
to study animals in a controlled place. where the person studying the animal has controll of the environment... like in a zoo
Their environment changed and they could no longer survive.
Adaptation (I'm studying the same thing ;)
A species either survives in its environment or the environment kills it.if a species is well adapted to the environment it thrives.
Simply mutation and natural selection against the backdrop of the immediate environment.
By comparing body structures of living organisms...By studying fossils...And comparing the early development of different organisms.
Analysis of DNA helps scientists establish an evolutionary classification scheme by comparing the genetic sequences of different organisms. The more similar the DNA sequences are between two species, the more closely related they are believed to be. By studying the similarities and differences in DNA, scientists can determine how different species are related to one another and create a classification scheme based on their evolutionary relationships.
Scientists use ancestors and DNA to group species.
