Question
First Posting The question you are addressing for your first post is: What do you think is the biggest threat to bodies of water and/or the organisms that live in them in the Pacific Northwest? For this question "bodies of water" can be any type of wetland, rivers, lakes, Puget Sound, etc. You can focus on a threat to a specific ecosystem type or location (e.g. bog, marsh, Puget Sound, etc.) or on a specific organism that lives in that ecosystem (e.g., Chinook salmon, Orcas, great blue heron, etc.). Note this organism cannot be the same as the one you are researching for your species report! 1. Determine what body of water or organism you are focusing on. 2. Decide which threat to that body of water or organism is the greatest or the most immediate threat. 3. Find information from a scientific study that supports your point of view. 4. Post this information. Your first post must include: What is the specific threat and what is it threatening (e.g., wetlands or salmon or ...)? A direct quote with specific information from a scientific study that supports your claim. Example of bad quote "water pollution is a threat to the Puget Sound" Example of good quote "levels of nitrogen in the Puget Sound were two times higher this summer than the previous summer" Complete citations for your information (name of newspaper/journal, author, title, date, title of website where found and complete url.Explanation / Answer
Overexploitation of aquatic organisms (for example: fishes, Salmon run etc ) for various purposes is the greatest threat to marine environments.This results in the loss of genetic diversity and the loss in the relative species abundance of both individual and /or groups of interacting species.Over-fishing cause changes in the genetic structure of fish populations due to loss of some alleles. Thus, genetic diversity gets reduced. Apart from this, air and water pollution, sedimentation and erosion, and climate change also plays a key role in threatening the aquatic biodiversity.
1. Water body is River and the organisms we are focussing here are Fishes and Salmon run.
2. The immediate threat to the organism is the loss of genetic diversity.
