22 Ιουλ 2024 · This study demonstrates the erosion of fish TP, an additional process that results in lower TP of individuals of a given size, which may exacerbate the effects of fishing on the food web.
24 Νοε 2023 · Sediment damage to macrophytes impacts on the shelter and food for fish and invertebrates (Wood and Armitage, 1997). Increased sediment concentrations can also lead to the reduction of both the number and diversity of macroinvertebrates which are an important food for fish.
14 Ιουν 2013 · Soil erosion is one of the most serious threats facing world food production. Each year about 10 million ha of cropland are lost due to soil erosion, thus reducing the cropland available for world food production.
The most conspicuous effect of cultural eutrophication is the creation of dense blooms of noxious, foul-smelling phytoplankton that reduce water clarity and harm water quality (Figure 2).
1 Ιουν 2024 · Pollution can affect aquatic organisms in a number of ways, including decreasing the amount of dissolved oxygen, changing the pH of the water, and introducing toxic chemicals. These alterations can be lethal to different aquatic organisms, and might cause large-scale mortalities.
Soils that affect human health include natural soil, which usually has little anthropogenic contamination, and soils in agroecosystems, urban areas, mines, oil and gas extraction areas, landfill sites and other locations where anthropogenic contamination is more likely.
1 Αυγ 2023 · The occurrence of low levels of dissolved oxygen resulting from algal bloom leads to fewer number of fishes, which is a consequential loss of important food sources for mammals (that include sea lions) and wading birds (such as herons), thereby leading to the death of shore birds and marine animals that depends on fish for their survival ...
