Ecological Studies of Symbiosis in Convoluta roscoff ensis
The size of the Convoluta roscoffensis population on a beach in Herm, Channel Islands is subject to wide seasonal variation, being very low in early summer and high in autumn and winter. Of the ecological factors measured, only light -expressed a s photosynthetically active radiation showed a correlation with population size. Low worm numbers, and also low numbers of algae and chlorophyll a con...
متن کاملSymbiosis Studies in Microbial Ecology
Symbiosis has long fascinated scientists: how are microbe and microbe interacting together, and how are microbes associated with host insects, animals and plants? Those studies provide deep insights into co-evolution of life showing how microorganisms have created specific niches closely associated with different organisms, how they have sustained the life of host organisms and how microbes as ...
متن کاملIntraspecific diversity and ecological zonation in coral-algal symbiosis.
All reef-building corals are obligately associated with photosynthetic microalgal endosymbionts called zooxanthellae. Zooxanthella taxonomy has emphasized differences between species of hosts, but the possibility of ecologically significant zooxanthella diversity within hosts has been the subject of speculation for decades. Analysis of two dominant Caribbean corals showed that each associates w...
متن کاملImpact assessment of an invasive flatworm, Convoluta convoluta, in the Southern Gulf of Maine
Convoluta convoluta (Abildgaard 1806) is a small (2–3 mm long) acoellous turbellarian flatworm from Europe that has invaded the Gulf of Maine within the last 5 years. Although it has been reported in densities of up to 19 individuals/cm, its ecological impact remains unknown. In its native habitat, it consumes harpacticoid copepods and primary settling mussels < 0.5-mm shell length. This study ...
متن کاملThe direct and ecological costs of an ant-plant symbiosis.
How strong is selection for cheating in mutualisms? The answer depends on the type and magnitude of the costs of the mutualism. Here we investigated the direct and ecological costs of plant defense by ants in the association between Cordia nodosa, a myrmecophytic plant, and Allomerus octoarticulatus, a phytoecious ant. Cordia nodosa trees produce food and housing to reward ants that protect the...
