17、 standardize sampling and extraction methods for soil macro-invertebrates in several European (temperate) and tropical countries. These methods are needed for the following purposes: biological classification of soils, including soil quality assessment (e.g. References 21, 32 and 41); terrestrial bi

18、o-indication and long-term monitoring (e.g. References 71, 79, 80 and 81).Data collected using standardized methods can be evaluated more accurately as it allows more reliable comparison between sites (e.g. polluted vs non-polluted sites, changes in land-use practices).Soils of the world host an abu

19、ndance of highly diverse macro-invertebrate communities. Their biology and ecology have been widely studied. Soil invertebrates are irreplaceable actors of soil formation and conservation in natural ecosystems. Their relevance to the soil system comes from their abundance and diversity, and also fro

20、m their role in key biological processes. They are sensitive indicators of soil quality and recognized agents of its fertility (e.g. References 63 and 56). Among the wide diversity of species, adaptive strategies and size ranges represented, one specific group, also called “soil ecosystem engineers”

21、, includes large invertebrates that actually determine the activities of other smaller organisms through the mechanical activities they produce in soil (e.g. References 24 and 49).Soil macro-invertebrates span a wide range of ecological functions in soil: decomposition of organic matter, through the

22、ir own activity and by stimulating the soils microbiological activity (e.g. References 8, 10 and 40), predation that plays an important part in food webs (e.g. References 16, 55, 61, 64 and 68), soil aggregation by the production of organo-mineral structures (e.g. nests, galleries, casts) that can l

23、ast for days, months or years, and soil bioturbation (e.g. Reference 32), etc. These characteristics, coupled with in-depth taxonomic knowledge, has enabled their use as study organisms in several research programmes dealing with the impacts of forest practices (e.g. References 18, 40, 50, 62, 65 an

24、d 75) or crop management practices (e.g. References 15, 25, 31, 33, 34, 37, 42, 60 and 66). These features make them suitable organisms for use as bio-indicators of changes in soil quality, especially with respect to land-use practices and pollution (e.g. References 26, 39, 48, 52, 53, 59, 65 and 79

25、).The method proposed in this part of ISO 23611 covers the sampling of all soil macro-invertebrates. However, the sampling of earthworms is already covered in ISO 23611-1. This method is described in ISO 23611-1:2006, Annex C, as an alternative sampling method for earthworms.BS EN ISO 23611-5:2013 I

26、SO 23611-5:2011 (E)iv INTERNATIONAL STANDARD Soil quality Sampling of soil invertebrates Part 5:Sampling and extraction of soil macro-invertebrates1 ScopeThis part of ISO 23611 specifies a method for sampling, extracting and preserving macro-invertebrates from soils, including the litter zone. The p

27、roposed method is a prerequisite for using these animals as bio-indicators (e.g. to assess the quality of a soil as a habitat for organisms). The main premise of this method is rapid assessment (completing the sampling of a plot in one or two days with only basic equipment and a small number of fiel

28、d assistants) in order to be able to address all the taxonomic groups of soil macro-invertebrates at the same time and in the same place. The Tropical Soil Biology and Fertility (TSBF) method has evolved and some modifications have been introduced in order to use it in temperate regions.The sampling

29、 and extraction methods in this part of ISO 23611 are applicable to almost all types of soil, with the exception of soils in extreme climatic conditions (hard, frozen or flooded soils) and matrices other than soil, e.g. tree trunks, plants or lichens.A sampling design is specified in ISO 23611-6.NOT

30、E 1 The method specified in this part of ISO 23611 is based on guidelines developed under the Tropical Soil Biology and Fertility Program (TSBF method)7.NOTE 2 Basic information on the ecology of macro-invertebrates and their use can be found in the references listed in the Bibliography.2 Terms and

31、definitionsFor the purposes of this document, the following terms and definitions apply.2.1macro-invertebratessoil organism whose longest dimension is greater than 10 mmNOTE See Annex A for further details.EXAMPLE These include especially the following groups: Oligochaeta, Gastropoda, Chilopoda, Dip

32、lopoda, Isopoda, Arachnida, plus various insects: Coleoptera, Orthoptera, Hymenoptera, Hemiptera, Dermaptera, Lepidoptera (larvae) and Diptera (larvae).2.2blotted massmass of individuals after preservation in formalin or ethanol (when the substance used for preservation has been absorbed by the tiss

33、ues)3 PrincipleSoil macro-invertebrates are collected in the field using a metallic frame to delimit the soil surface of the sampling point. Macro-invertebrates present in litter and soil are picked up separately. In temperate regions, a reagent is used to extract macro-invertebrates from soil. The

34、sampling is completed by hand-sorting. Animals are preserved and transported to the laboratory for further identifications (e.g. References 11, 12, 13, 14, 17, 19, 20, 22, 23, 27, 28, 29, 30, 35 ,36, ,38, 45, 46, 47, 54, 57, 70, 72, 73, 76, 77, 78 and 84). Abundance values are usually recalculated r

36、with soft body parts, which can be transferred to ethanol after about 4 d fixation).4.3 Formalin, 0,2 % (volume fraction), prepared by diluting 25 ml of formalin (39 %) in 5 l of water, for soil macro-invertebrate extraction.5 ApparatusUse standard laboratory equipment and the following.5.1 Petri di

40、50 mm) made of stainless steel and with sharpened edges to delimit the sampling point where animals are sampled from the litter layer and soil.5.23 Watering can.5.24 Pair of scissors, to cut vegetation inside the frame.5.25 Field balances.6 Field procedure6.1 GeneralSampling should take place when a

41、ccessible biodiversity is thought to be largest. In temperate regions, it corresponds to spring or autumn, and in the tropics, it should take place towards the end of the rainy season.When sampling soil invertebrates, it is strongly recommended that the site be physico-chemically characterized. In p

42、articular, pH, particle size distribution, C/N ratio, organic carbon content and water-holding capacity should be measured using ISO 10390, ISO 10694, ISO 11274, ISO 11277, ISO 11461, ISO 11465.6.2 Collecting macro-invertebrates from the litter zoneAt each sampling point (= monolith) (previously def

43、ined according to sampling design rules), a litter sample is collected using a metallic frame (5.22). The metallic frame is pressed into the litter by hand. The litter inside the frame is removed and checked manually in the field using a large tray (5.11). Litter invertebrates are preserved in 4 % f

44、ormalin (4.2).6.3 Collecting macro-invertebrates from soil6.3.1 GeneralIn temperate countries, the extraction of soil macro-invertebrates is carried out in two steps (see 6.3.2.1 and 6.3.2.2), while in tropical countries only the second step shall be performed (see 6.3.3).6.3.2 Temperate regions6.3.

45、2.1 Formalin extractionThe soil surface delimited by the metallic frame (5.22) is sprayed with 0,2 % formalin (4.3) using a watering can (5.23). Two applications of 1,5 l of formalin are performed at intervals of about 10 min. Soil invertebrates coming up to the surface are collected and preserved i

46、n vials (5.3) containing formalin (4.2).6.3.2.2 Hand-sorting of “passive” macro-invertebratesAt the end of the formalin extraction, the metallic frame (5.22) is removed and the upper 150 mm of soil is excavated within the frame area (250 mm 250 mm). The excavated soil is placed in a plastic bag (5.1

47、8) that can be closed with a cover to prevent animals from escaping from the soil sample.3BS EN ISO 23611-5:2013 ISO 23611-5:2011 (E)Appropriate sub-samples of soil are taken from the container and spread on a large tray (5.11). Macro-invertebrates are collected and preserved in vials (5.3) with for

48、malin (4.2). When hand-sorting is finished, the excavated soil is replaced to avoid creating holes on the sampling site.6.3.3 Tropical regionsIn tropical countries, soil macro-invertebrates are sampled using a 250 mm 250 mm 300 mm deep soil monolith. The monolith is isolated by cutting with a spade

49、(5.8) a few centimetres outside the quadrate (metallic frame) and then digging a 20 mm wide by 300 mm deep trench around it. This facilitates cutting of the sample into horizontal strata and collecting animals escaping from the block.The delimited block is divided into three layers, 0 mm to 100 mm, 100 mm to 200 mm and 200 mm to 300 mm, and the soil and litter material is hand-sorted in trays (5.11).
