Fishing and introduced species are among the most important stressors affecting freshwaters and can also be strong selective agents.
In this study we have found that, although most students enjoy being at medical school, various course-related stressors affect them and these are related to the type of programme being followed.
Salinity is one of the most consequential environmental stressors affecting marine organisms.
Our results add further evidence that multiple-stressor interactions, notably increased salinity with other stressors, affect a variety of invertebrate taxa across different habitats of stream communities.
Although environmental stressors affect natural systems in a multitude of ways, the interactive effect of multiple stressors on ecological assemblages remains largely misunderstudied.
Our results provided more detailed understanding on how environmental stressors affect freshwater organisms, and further catchment management should integrate the combined effect of different environmental stressors on streams.
Many stressors affect water hygiene and sanitation.
No indications were found that different types of stressors affect these body regions differently.
These stressors affect the evolution of species living in these habitats, and their capacity to adapt to these stressors ultimately determines their distribution [ 16- 19].
Exposure to antenatal stressors affects autonomic regulation in fetuses.
