29、11 has been drawn up since there is a growing need for the standardization of terrestrial zoological field methods. Such methods, mainly covering the sampling, extraction and handling of soil invertebrates, are needed for the following purposes: g127 biological classification of soils including soil

30、 quality assessment (e.g. References 21, 25, 27); g127 terrestrial bioindication and long-term monitoring (e.g. References 13, 26); g127 evaluation of the effects of chemicals on soil animals (References 15, 22). Data for these purposes are gained by standardized methods since they can form the basi

31、s 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 biological classification concepts in terrestrial (i.e. soil) habitats have so far been relatively rarely used in comparison t

32、o aquatic sites. Originally, the methods described here were developed for taxonomical and ecological studies, investigating the role of enchytraeids in various soil ecosystems. These animals without doubt belong to the most important soil invertebrates in temperate regions (mainly in acidic soils 5

33、). Their influence on soil functions like litter decomposition and nutrient cycling is well-known 14, 19. Due to their number which is often very high (and to their population biomass), they are also important in many terrestrial food-webs 4. Some species have unintentionally been distributed by man

34、 in many soils of the world. Since it is neither possible nor useful to standardize methods for all soil organisms, the most important ones have been selected. Microbiological parameters are already covered by existing ISO guidelines (e.g. ISO 10381-6 29, ISO 14240-1 37and ISO 14240-2 38). 4DIN EN I

35、SO 23611-3:2011-09 EN ISO 23611-3:2011 (E) 1 Scope This part of ISO 23611 specifies a method for sampling, handling and extracting enchytraeids from terrestrial field soils as a prerequisite for using these animals as bioindicators (e.g. to assess the quality of a soil as a habitat for organisms). B

36、asic information on the ecology of enchytraeids and their use as bioindicators in the terrestrial environment are included in the Bibliography. This part of ISO 23611 applies to all terrestrial biotopes in which enchytraeids occur. The sampling design of field studies in general is specified in ISO

37、10381-1. These details can vary according to the climatic/regional conditions of the site to be sampled and an overview on the determination of effects of pollutants on enchytraeids in field situations is given in Reference 6. Methods for some other soil organism groups such as earthworms or micro-a

38、rthropods are specified in ISO 23611-1 and ISO 23611-2. This part of ISO 23611 is not applicable for semi-terrestrial (i.e. living in or close to the pure water) soils and might be difficult to use under extreme climatic or geographical conditions (e.g. in high mountains). When sampling soil inverte

39、brates, it is highly recommendable to characterize the site (e.g. concerning climate and land use). However, such a characterization is not covered by this part of ISO 23611. ISO 10390, ISO 10694, ISO 11272, ISO 11274, ISO 11277, ISO 11461 and ISO 11465 are more suitable for measuring pH, particle s

40、ize distribution, C/N ratio, organic carbon content and water holding capacity. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 enchytraeids small soil-inhabiting worms (a few millimetres to several centimetres in length) belonging to the fam

41、ily Enchytraeidae, order Oligochaeta (class Clitellata, phylum Annelida) EXAMPLE Species of the genera Enchytraeus, Fridericia or Cognettia. 3 Principle Enchytraeids at a certain site are sampled from the soil by using a split corer (diameter usually 3 cm to 6 cm). After sampling, the soil samples c

42、ontaining the enchytraeids are transported to the laboratory. Then the enchytraeids are extracted from soil by means of a wet extraction method. (This approach has been well-known for a long time 11, 17, 20.) After extraction, the enchytraeids are identified alive and, if required, preserved in such

43、 a way that they can be stored in a collection indefinitely (e.g. for taxonomical purposes). 5DIN EN ISO 23611-3:2011-09 EN ISO 23611-3:2011 (E) The determination of the biomass of enchytraeids is also described in this part of ISO 23611. The abundance and biomass values can be recalculated to the a

44、rea of the soil corer or, more rarely, volume parameters. NOTE 1 The sampling of enchytraeids is often included in much broader monitoring programmes which try to cover the whole soil fauna or parts of it (e.g. the mesofauna). The design of such programmes is not included in this part of ISO 23611 (

45、but see e.g. Reference 3). NOTE 2 Some hints for the taxonomy of enchytraeids are given in Annex A. 4 Reagents 4.1 Tap water (without toxic properties, e.g. due to copper contamination). 4.2 Ethanol, 70 % (volume fraction). 4.3 Bengalred, 4,5,6,7-Tetrachloro-2,4,5,7-tetraiodofluorescein formulated a
