27、n of sampling and extraction methods of soil micro-arthropods. These methods are needed for the following purposes: g127 biological classification of soils including soil quality assessment (e.g. References 31, 32, 35, 41, 45, 46); g127 terrestrial bioindication and long-term monitoring (e.g. Refere

28、nces 1, 7, 17, 40, 42). Data collected by standardized methods can be more accurately evaluated allowing more reliable comparisons between sites (e.g. polluted versus non-polluted sites, changes in land-use practices). From the several micro-arthropod groups, Collembola and Acarina are the most stud

29、ied in soil ecology. Their relevance for the soil system comes from their high abundance and diversity, and also from their role in key biological processes. Collembola and Oribatid mites act mainly as catalysts in organic matter decomposition 4, 20, whereas predacious mites may act as webmasters in

30、 soil food webs 9. These characteristics, allied to a widespread taxonomic knowledge, allowed their use as study organisms in several research programmes dealing with the impacts of forest practices (e.g. References 12, 13, 14, 15, 18, 19, 21, 22, 23, 25, 26, 27, 28, 29, 30, 31, 33, 34, 37, 38, 39)

31、or crop management practices (e.g. 6, 11, 16, 24). These features make them suitable organisms to be used as bio-indicators of changes in soil quality, especially due to land-use practices and pollution 43. 4DIN EN ISO 23611-2:2011-09 EN ISO 23611-2:2011 (E) 1 Scope This part of ISO 23611 specifies

32、a method for sampling, extracting and preserving collembolans and mites from field soils as a prerequisite for using these animals as bio-indicators (e.g. to assess the quality of a soil as a habitat for organisms). Basic information on the ecology of micro-arthropods and their use can be found in t

33、he references listed in the Bibliography. The sampling and extraction methods of this part of ISO 23611 are applicable to almost all types of soils. Exceptions may be soils from extreme climatic conditions (hard, frozen or flooded soils) and other matrices than soil, e.g. tree trunks, plants or lich

34、ens. For the sampling design of field studies in general, see ISO 10381-1. Methods for some other soil organism groups such as earthworms are covered in other parts of ISO 23611. This part of ISO 23611 does not cover the pedological characterization of the site which is highly recommendable when sam

35、pling 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 Terms and definitions For the purposes of this document, the follow

36、ing terms and definitions apply. 2.1 micro-arthropods group which is defined by its small size (range size from 100 m to a few millimetres) making up a significant part of the below-ground food web in many terrestrial ecosystems NOTE This group is mainly composed by mites (Acarina), springtails (Col

37、lembola), Protura, Diplura, garden centipedes (Symphyla), Pauropoda, small centipedes and millipedes, and insects and their larvae from several orders (Diptera, Coleoptera, etc.). 3 Principle Soil samples are collected in the field using a split corer. Soil cores are placed in plastic tubes (or plas

38、tic bags) and transported to the laboratory. Afterwards, Collembola and Acarida are rapidly (within a few days) extracted by behavioural methods, using a MacFadyen apparatus, and preserved for future identifications 7, 40. In addition, preparation techniques are also described. Finally, abundance va

39、lues can be recalculated related to area (usually 1 m2), volume or weight (usually 1 kg). 5DIN EN ISO 23611-2:2011-09 EN ISO 23611-2:2011 (E) NOTE Alternative methods for extraction can be used under special circumstances. Flotation methods (e.g. the heptane flotation method) can be used in clay or

40、loamy soils and a Kempson extractor is advisable in the case litter is sampled 40. 4 Test materials 4.1 Biological material Collembola (springtails) are small wingless hexapods (from 150 m up to 9 mm length), having a distinctive head with a pair of antennae, without true compound eyes, with six abd

41、ominal segments and three pre-genital appendages in the abdomen. In the first segment, there is the ventral tube (or collophore) that is used for adhering to smooth surfaces. The name Collembola comes from this structure (from Greek colla = glue and embolon = bar). In the third segment, there is the

42、 tenaculum, that holds the jumping apparatus on its normal position. This jumping appendage, the furcula (or spring), when it exists, is located in the fourth segment. Springtails live in litter and soil, and have very distinctive life forms. They belong to the class Collembola, and can be separated

43、 into 18 families 17. Soil mites are small chelicerate arthropods related to spiders (length from 150 m up to 5 mm), living in soil and litter, and also presenting very distinctive life forms. They belong to the class Arachnida, subclass Acarida, and can be separated into four groups: Cryptostigmata

44、 (Oribatida), Mesostigmata (Gamasida), Prostigmata (Trombidiformes) and Astigmata. NOTE Some hints for the taxonomy of springtails and mites are given in Annex A. 4.2 Reagents Unless otherwise specified, use only reagents of good quality and distilled water. 4.2.1 Propan-2-ol, 80 % (volume fraction)
