Such methods, mainly cove

29、ring the sampling, extraction and handling of soil invertebrates, are necessary for the following purposes: g127 biological classification of soils including soil quality assessment 15,17,28; g127 terrestrial bio-indication and long-term monitoring 9,10,13,24; g127 evaluation of the effects of chemi

30、cals on soil animals (ISO 11268-3). Data for these purposes are gained by standardized methods since they can form the basis for far-reaching decisions (e.g. whether a given site should be remediated or not). In fact, the lack of such standardized methods is one of the most important reasons why bio

31、-classification and bio-assessment in terrestrial (i.e. soil) habitats has so far been relatively rarely used in comparison to aquatic sites. Nematodes are an important and major part of the soil fauna. Some authors estimate that this group is probably the most dominant one of the multicellular orga

32、nisms (Metazoa) on earth. Nematodes occur from the Antarctic to the tropics and from deep sea sediments to mountain regions. They are active in every place with sufficient water and organic material. The species diversity and functional variety are impressive. Nematodes are commonly known as parasit

33、es of animals and plants, but the major part of the nematode fauna participates in decomposition processes by feeding on bacteria and fungi. Nematodes occur in high numbers (5 000 to 100 000)/kg fresh soil and with a high (20 to 100) species diversity in almost every soil sample. Moreover, there is

34、a broad ecological spectrum of feeding types and food web relations among the nematodes such as bacterivores, fungivores, herbivores, predators and omnivores 27,28. These factors make the group highly suitable as indicators for ecological soil quality, but standardization of methods is urgently need

35、ed for comparison and combination of results. In the past 100 years, nematology has developed strongly from the viewpoint of agriculture, advisory sampling and phytosanitary regulations because some terrestrial nematodes cause a lot of damage in crops. With respect to methods, there are several “sch

36、ools” in different parts of the world with their own history, practical advantages and disadvantages. A comprehensive overview is given by Oostenbrink 14and Southey 22,23. The more recently described methods (or variants) are often developed with special interest to certain plant-parasitic species.

37、Since Bongers 4introduced the Maturity Index, the use of nematodes in bio-indication for soil quality has increased rapidly. Nematodes are now used for ecological soil research and monitoring in several countries all over the world. Monitoring activities make special demands on methodology, for inst

38、ance, that a large number of soil samples is processed on a routine basis against reasonable costs. Some of the methods originally developed for advisory sampling in agriculture are very suitable for ecological research. They form the basis for specific variants described in this document. 4DIN EN I

39、SO 23611-4:2011-09 EN ISO 23611-4:2011 (E) 1 Scope This part of ISO 23611 specifies a method for sampling and handling free-living nematodes from terrestrial field soils as a prerequisite for using them as bio-indicators (e.g. to assess the quality of a soil as a habitat for organisms). This part of

40、 ISO 23611 applies to all terrestrial biotopes in which nematodes occur. The sampling design of field studies in general is specified in ISO 10381-1. This part of ISO 23611 is not applicable to aquatic nematodes because these nematodes do not pass through the filter. Methods for some other soil orga

41、nism groups such as earthworms, enchytraeids or collembolans are covered in other parts of ISO 23611. The nematodes that are characterized by the proposed procedure are all the free-living forms of nematodes found in soil. They include non-plant-feeding nematodes as well as ectoparasitic plant-feedi

42、ng nematodes and free-living stage of endoparasitic nematodes. The quantification of obligate plant-feeding nematodes in roots requires specific methods. NOTE Basic information on the ecology of nematodes and their use as bio-indicators can be found in the bibliography. This part of ISO 23611 does n

43、ot cover the pedological characterization of the site which is highly recommendable when sampling soil invertebrates. ISO 10390, ISO 10694, ISO 11272, ISO 11274, ISO 11277, ISO 11461 and ISO 11465 are more suitable for measuring pH, particle size distribution, C/N ratio, organic carbon content and w

44、ater-holding capacity. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 nematode small, non-segmented free-living worm (up to a few millimetres in length) belonging to the class Nematoda NOTE Nematodes without a soil-inhabiting stage are not i

48、 proposed by Bongers 4,5NOTE The principle is analogous to the r-K life strategies during succession, distinguished in fundamental ecology. Non-plant-feeding nematode families are classified to one of the five cp-groups. This is also the basis for the calculation of the Maturity Index. 3 Principle N

49、ematodes are collected in soil samples with a small cylindrical core (diameter: circa 2 cm; length: 10 cm) or an auger (see Figure A.2). For monitoring purposes, the soil samples are combined in a bulk-sample from a homogeneous area. The total number of samples to be taken depends on the investigated surface area and its homogeneity (e.g. pedology, culture). The individual samples can be gathered in the field in a standard plastic bag or plastic bucket. The combin
