Conservation and management of Senanayake samudra reservoir ecosystem in Sri Lanka

Wijeyaratne, M.J.S. (The University of Michigan, USA, 1993)
The effects of Relic fauna on initial patch colonisation in a British saltmarsh

Chandrasekera, L.W.H.U.; Frid, C.L.J. (Netherlands Journal of Aquatic Ecology, 1996)

When a disturbance impacts an area it rarely leads to a complete defaunation, some individuals survive forming a relic fauna. Relic fauna in azoic patches in an intertidal soft-bottom habitat were simulated by the separate ...
Effects of human trampling on tidalflat infauna

Chandrasekera, L.W.H.U.; Frid, C.L.J. (Aquatic Conservation: Marine and Freshwater Ecosystems, 1996)

1.?Human trampling has been shown to be detrimental to the survival of fauna of terrestrial habitats and on rocky coastal areas. However, its effects on saltmarsh benthic infauna were not known. 2.?The abundance of ...
Indicator organisms of environmental conditions in a lotic waterbody in Sri Lanka

Gamlath, G.A.R.K.; Wijeyaratne, M.J.S. (Sri Lanka Association for Fisheries and Aquatic Resources, 1997)
Alaboratoryassessment of the survival and verticalmovement of twoepibenthicgastropodspecies, Hydrobia ulvae (Pennant) and Littorina littorea (Linnaeus), afterburial in sediment

Chandrasekera, L.W.H.U.; Frid, C.L.J. (Journal of Experimental Marine Biology and Ecology, 1998)

Physical disturbance may result in the burial of the epibenthic fauna in sediment. The patches thus created undergo a `recovery' which may include the buried fauna migrating through the sediment to regain their original ...
The restoration of mud flats invaded by common cord-grass (Spartina anglica, CE Hubbard) using mechanical disturbance and its effects on the macrobenthic fauna

Frid, C.L.J.; Chandrasekera, L.W.H.U.; Davey, P. (Aquatic Conservation: Marine and Freshwater Ecosystems, 1999)

1. The growth of the common cord-grass, Spartina anglica, across many temperate coastlines has resulted in a reduction in the extent of tidal flats. Its colonization has reduced the abundance of macrobenthic fauna and hence ...
