Christopher Harley, a professor of zoology at UBC and senior author on the study, says consumers like limpets, sea otters or starfish are very important to maintaining biodiversity,
especially in aquatic ecosystems.
Aggression toward humans and native animal species, the depletion of submerged
vegetation in aquatic ecosystems and degraded water quality due to droppings are among the negative impacts of mute swan populations, environmental experts say.
Mass extinctions of the big beasts of the jungles, grasslands and oceans could already be adding to emissions, according to a new study based on
fieldwork in aquatic ecosystems.
Using an artificial stream system, researchers found that amphetamine residues altered insect and microbial
life in aquatic ecosystems.
There is considerable uncertainty surrounding emerging
contaminants in aquatic ecosystems and groundwater, and a recent Penn State study of compounds from pharmaceuticals and personal care products didn't add much clarity.
NEON collects and produces data on precipitation patterns, soil and groundwater dynamics, interactions with vegetation, and processes such as nutrient cycling and food web
dynamics in aquatic ecosystems to support the comprehensive study of water cycles throughout diverse ecosystems.
So far, however, there has been no reliable knowledge as to whether microplastic
particles in aquatic ecosystems promote the development of special bacterial communities or even the spread of pathogens.
A World Bank report said in February 2015 that climate change is likely to increase river salinity leading to shortages of drinking water and irrigation and significant
changes in aquatic ecosystems in the southwest coastal areas during the dry season by 2050.
