Monitoring has also suffered because it relies largely on correlative analyses rather than on the manipulative experiments that have been more fashionable among ecologists.Synovial-Fluid 发表于 2025-3-25 16:08:10
Niere und harnableitende Organeecological influences of water in all biomes. It reflects also the riparian influence of running waters: Britain alone has 80 000 km of streams and rivers, yet river drainage from the whole of Europe still represents only 8% of the world’s total (Chorley, 1969).椭圆 发表于 2025-3-25 21:25:54
Birds as monitors of pollutants,bs, may be useful, provided that species are chosen carefully. Less sampling may be necessary if birds can reflect pollutant levels in the whole ecosystem or over a broad area. In addition, since they are high in food chains, birds may reflect pollutant hazards to humans better than do most invertebassent 发表于 2025-3-26 01:56:02

Birds as monitors of radionuclide contamination,r organic compounds. This may be because in the past elevated levels of environmental contamination with radionuclides have generally only been a problem in a relatively few and limited geographical localities. Most of these localities have either prohibited or greatly restricted public access becau
