Such met

27、hods, mainly covering the sampling, extraction and handling of soil invertebrates, are necessary for the following purposes: g127 biological classification of soils including soil quality assessment 21, 26, 34; g127 terrestrial bioindication and long-term monitoring9, 12, 28; g127 evaluation of the

28、effects of chemicals 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 standardised methods is one of the most important

29、 reasons why bio-classification and bio-assessment in terrestrial (i.e. soil) habitats has so far relatively rarely been used in comparison to aquatic sites. Originally, the methods described here were developed for taxonomical and ecological studies, investigating the role of earthworms in various

30、soil ecosystems. These animals are without doubt the most important soil invertebrates in temperate regions and, to a lesser extent, in tropical soils 25, 13, 15. Since Darwin (1881), their influence on soil structure (e.g. aeration, water holding capacity) and soil functions like litter decompositi

31、on and nutrient cycling is well-known 8. Due to their often very high biomass they are also important in many terrestrial food-webs. Since it is neither possible nor useful to standardize methods for all soil organisms, the most important ones have been selected. 4DIN EN ISO 23611-1:2011-09 EN ISO 2

32、3611-1:2011 (E) 1 Scope This part of ISO 23611 specifies a method for sampling and handling earthworms from 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). Basic information on the ecology of earthworms and the

33、ir use as bioindicators in the terrestrial environment can be found in the references listed in the bibliography. This part of ISO 23611 applies to all terrestrial biotopes in which earthworms occur. The sampling design of field studies in general is specified in ISO 10381-1 (see also Reference 38)

34、and guidance on the determination of effects of pollutants on earthworms in field situations is given in ISO 11268-3. These details can vary according to the national requirements or the climatic/regional conditions of the site to be sampled (see also Annex C). This part of ISO 23611 is not applicab

35、le for semi-terrestrial soils and it can be difficult to use under extreme climatic or geographical conditions (e.g. in high mountains). Methods for some other soil organism groups, such as collembolans, are covered in other parts of ISO 23611. This part of ISO 23611 does not cover the pedological c

36、haracterization 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 water-holding capacity. 2 T

37、erms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 earthworm megadrile soil-inhabiting earthworms (length of adult individuals: few centimetres to more than 1 m) belonging to the order Oligochaeta (class Clitellata, phylum Annelida) EXAMPLE Species

38、 of the families Lumbricidae (Holarctic), Glossoscolecidae (Latin America), Eudrilidae (Africa) or Megascolecidae Asia, North America (Pacific Coast). 2.2 peregrine species earthworms occurring in many regions world-wide today, usually introduced by man NOTE 1 Well-known examples of peregrine specie

39、s are several lumbricid species like Aporrectodea caliginosa (originally coming from Eurasia, but now living also in the Americas and Australia) or the pan-tropical species Pontoscolex corethrurus (probably coming from Northern Brazil and/or the Guyanas).

40、:2011-09 EN ISO 23611-1:2011 (E) 2.3 clitellum ring or saddle of epidermal thickening only in mature worms which is near the anterior and eventually forms the cocoon 3 Principle Earthworms at a certain site are sampled from the soil by using a combination of two different methods: g127 hand-sorting

41、animals from a certain area (e.g. 0,25 m2) or volume (e.g. 50 cm g117 50 cm g117 20 cm); g127 extraction of worms from the soil by applying formalin. Both methods are well-known for a long time 5,20. After extraction, the earthworms are fixed and transported to the laboratory. There they are preserv

42、ed in a way that they can be stored in a collection indefinitely (e.g. for taxonomical purposes). In addition, the determination of the biomass of earthworms is described. Finally, abundance and biomass values can be recalculated to area (usually 1 m2) or, more rarely, volume parameters. NOTE 1 Alte

43、rnative methods can be useful under special circumstances (e.g. electrical extraction or the use of mustard as a chemical expellent), but cannot be recommended as a general procedure (see Annex A). In addition, the use of other extraction chemicals than formalin seems to have no advantages concernin

44、g extraction efficiency 11; 33. NOTE 2 The sampling of earthworms is often included in much broader monitoring programs, trying to cover the whole soil fauna or parts of it (e.g. the macrofauna). The design of such programs is not included in this part of ISO 236111. NOTE 3 Some hints for the taxono

45、my of peregrine (occurring in many regions world-wide) earthworms, mainly belonging to the family Lumbricidae, are given in Annex B. 4 Reagents 4.1 Formalin formaldehyde solution 4 % (volume fraction). 4.2 Formalin formaldehyde solution 37 % (volume fraction). 4.3 Ethanol, 70 % (volume fraction). 5

46、Apparatus Use standard laboratory equipment and the following. 5.1 Plastic vessels, capacities 250 ml and 500 ml, for storing the worms. 5.2 Plastic gloves. 5.3 Forceps. 5.4 Piece of thick plastic sheeting, 1 m2to 2 m2. 5.5 Spade or shovel. 5.6 Dissecting microscope, with low magnification (10 to 40

47、 times). 5.7 Balance, able to weigh from 0,01 g to 200 g. 5.8 Water-can, preferably 20 l, with water (20 l per sampling plot). 6DIN EN ISO 23611-1:2011-09 EN ISO 23611-1:2011 (E) 5.9 Watering can. 5.10 Pencil, notebook, water resistant marker, labels that go in the vessel. 5.11 Thermometer, e.g. for

48、 measuring air temperature. 5.12 Drying cabinet, for soil moisture determination. 6 Procedure 6.1 Sampling of the earthworms 6.1.1 General Sampling of earthworms is done by a combination of two different methods: hand-sorting and formalin extraction. Based on several comparative studies, this combination is clearly recommended in the various reviews on earthworm ecology (e.g. References 7, 8, 15). Sampling should be done at times of the year
