摘要:Abstract(#br)While most environmental scientists appreciate the importance of appropriate spatial and temporal scales for environmental assessment and monitoring, the issue of how to determine these scales has not (in our view) been addressed in sufficient depth. Here we defi...

摘要:... These are important from a conservation viewpoint but, for long-term evaluations, it is important to monitor ecosystems. The need for long-term monitoring plots has been recognized for some time in forest ecology. Of the natural ecosystems, forests are some of the most diff...

摘要:... Due to complexities in collecting 3-dimensional data, most ecosystem monitoring programmes reduce dimensionality when sampling, resorting to planar views. The resultant 'canopy effects' may bias data interpretation, particularly following disturbances. Canopy effects are espe...

摘要:Abstract(#br)Antarctic seabirds are important indicators of impacts and change in Southern Ocean ecosystems, but their isolated and remote breeding populations are challenging and expensive to assess and monitor using traditional methods. Taking account of dependent species s...

摘要:Abstract(#br)The collection of scientific data from commercial fishing vessels will play an important role in the future assessment of fish stocks and ecosystem monitoring. Currently fishing vessel acoustic data collections range from fully structured random/systematic surveys to...

摘要:Abstract(#br)As part of integrated biological-effect monitoring, the parasite fauna of the flounder Platichthys flesus (L.) was investigated at five locations in the German Bight, with a view to using parasite species as bio-indicators. Over a period of 6 years, parasites from 30...
