Relative impacts of morphological alteration to shorelines and eutrophication on littoral macroinvertebrates in Mediterranean lakes [PDF]
, 2015 Development of effective methods for assessing the ecological status of lakes based on littoral benthic fauna has been hampered by the lack of quantitative data on the relative impacts of key pressures on the benthic community.

Benthic quality evaluation of immersion zones of sediments dredging
Revue Paralia, 2013 Dredging operations pose the problem of sediment deposits to be evacuated by taking into account economic incidences and environmental aspects related to environmental protection. Coastal sediments are high biodiversity zones, where a multitude of living organisms have a special relationship with their substrate.

Habitat change driven by plant invasion restructures benthic diversity in intertidal wetlands
Global Ecology and ConservationSince its introduction to China in 1979, Spartina alterniflora has steadily expanded along the southeast coast of China and reshaped the intertidal ecosystem by altering the properties of sediments. These changes, in turn, will affect the composition and

Long-term change in benthopelagic fish abundance in the abyssal northeast Pacific Ocean [PDF]
, 2006 Food web structure, particularly the relative importance of bottom-up and top-down control of animal abundances, is poorly known for the Earth's largest habitats: the abyssal plains.
