Физиолого-биохимический отклик представителей фитоценозов литорали казачьей бухты на действие многофакторного загрязнения для оценки характера и степени антропогенного повреждения.

Dear Alex, Thanks. Could you please send me the english version of this paper?

regards

Dear Anant, I'm sorry, but the text in the Russian language. English version no/

Regards

There are many methods. This depends on your needs. Go to my profile and look at papers on benthic fauna and flora

what could be the most important impacts on marine biota caused by drilling? Specially on the projects located far from the shoreline?

You can see this publication in my profile: Borja, A.; I. Muxika, J. Franco, 2003. The application of a Marine Biotic Index to different impact sources affecting soft-bottom benthic communities along European coasts. Marine Pollution Bulletin, 46: 835-845. There is a case-study of drilling in offshore waters. You can get there other references. There are many references on drilling published

Thanks Angel. I intend to assess the impacts of over harvesting, pollution (sewage) and trampling on the intertidal fauna. What I wish to know is whether I should focus on specific taxa (molluscs, polychaetes etc) and some novel approaches to quantify these impacts? Please help.

If that is a soft-bottom intertidal, you can use approaches like AMBI and M-AMBI (look at many papers in my profile). If that is a rocky shore, you can find a method in my profile (Diez et al., 2012), for macroalgae. For fauna, you need to use multivariate methods, using software like PRIMER or CANOCO, using biotic and abiotic variables

Polychaetes are a good choice because their bioturbation activities makes them good candidates for contaminant retention.

Thanks Azubuike. Bivalves and polychaetes could be looked for in detail for contamination.

An intertidal ecosystem is usually affected by both natural and anthropogenic disturbances affecting community response. To look for specific community responses, whichever community you intend to analyze (and to my understanding the many suggestions advanced go in the right direction), you must be sure to be capable to distinguish between the two kinds of disturbances, unless you are interested in a specific pollutant like e.g. heavy metal retention or accumulation. Such distinction is not an easy matter unless you know the general traits of the natural physical disturbance regime that in intertidal zones is quite relevant as you will deal mostly with physically accomodated communities and thus more resistant to disturbance with a rather low response profile. Probably for an indicator based monitoring of coastal ecosystems the best communities in this respect would be the biologically accomodated ones at deeper zones less affected by physical disturbances typical of the intertidal zone.

Thank you Giovanni. The intertidal zones on the west coast of India (Mumbai and adjoining regions) are under severe pressure from pollution, sewage disposal and human trampling. From our preliminary surveys, we have categorized areas with distinct disturbance levels ranging from very low to very high. After referring to the literature available on the topic, we would look for changes in abundance patterns of various communities (polychaetes, molluscs, algae) across these sites. We also plan to take into account the environmental parameters from these sites on a regular basis to look for climatic influence on the diversity, distribution and abundances of these communities.

Thanks for help.

Hi

Here is a list of references of your interest:

Macrobenthos in the taxon Bivalvia, Polychaeta, Amphipoda, Echninoidea and Holothuroidea may be looked into to track environmental perturbation. You may also look into meiobenthos for the purpose as well. Interesting groups in this case are Copepoda, Foraminifera, Nematoda among others.

Few more to add up:

You can use Aztic Marine Biotic Index (AMBI). It is very useful software to monitor coastal ecosystem using benthic macrofaunal orgnisms particularly polychaetes. when we use this softwatre, need high level (upto species level) species classification.

Thanks Dola and Seerangan
