“…Sharratt et al, 2000). Deeper areas are however the true realm of troglobiont and stygobiont species and the assemblages they form typically present a very marked taxonomic and functional disharmony (Gibert & Deharveng, 2002).…”

“…While Botswana (Modisi 1983) and Namibia (Irish 1991;Christelis and Struckmeier 2001) are considered possible locations that may harbour an undocumented diversity of stygofauna, southern Africa as a whole is a likely subterranean hotspot, as similar geology, karst and calcrete aquifers to those observed in WA exist there (Pickford et al 1999). South Africa has the endemic subterranean amphipod family Sternophysingidae (Tasaki 2006), within the globally distributed superfamily Crangonyctoidea (Holsinger 1992) and the order Spelaeogriphacea (Sharratt et al 2000). The Spelaeogriphacea are only known from two other locations in the world (Brazil and Australia), indicating a shared Gondwanan distribution (Jaume 2008).…”

Abstract. Australia was historically considered a poor prospect for subterranean fauna but, in reality, the continent holds a great variety of subterranean habitats, with associated faunas, found both in karst and non-karst environments. This paper critically examines the diversity of subterranean fauna in several key regions for the mostly arid western half of Australia. We aimed to document levels of species richness for major taxon groups and examine the degree of uniqueness of the fauna. We also wanted to compare the composition of these ecosystems, and their origins, with other regions of subterranean diversity world-wide. Using information on the number of 'described' and 'known' invertebrate species (recognised based on morphological and/or molecular data), we predict that the total subterranean fauna for the western half of the continent is 4140 species, of which~10% is described and 9% is 'known' but not yet described. The stygofauna, water beetles, ostracods and copepods have the largest number of described species, while arachnids dominate the described troglofauna. Conversely, copepods, water beetles and isopods are the poorest known groups with less than 20% described species, while hexapods (comprising mostly Collembola, Coleoptera, Blattodea and Hemiptera) are the least known of the troglofauna. Compared with other regions of the world, we consider the Australian subterranean fauna to be unique in its diversity compared with the northern hemisphere for three key reasons: the range and diversity of subterranean habitats is both extensive and novel; direct faunal links to ancient Pangaea and Gondwana are evident, emphasising their early biogeographic history; and Miocene aridification, rather than Pleistocene post-ice age driven diversification events

“…Overall, interval spacing was applied in nine studies. These consisted of five ecological studies including one habitat (Prous et al, 2004), two community studies (Peck, 1976;Novak et al, 2012) and two nutrients studies (Chapman, 1983;Campbell et al, 2011), as well as two techniques (Kozel et al, 2017;Wynne et al, 2018) and two inventory studies (Braack, 1989;Sharratt et al, 2000).…”

“…Prous et al (2004) searched for ≥25 minutes at 2-m intervals. Lunghi et al (2014), Sharratt et al (2000) and Tobin et al (2014) performed TS using quadrat sampling at 7.5 minutes, 10 to 25 minutes, and 30 minutes per quadrat, respectively. Weinstein and Slaney (1995) employed a TS approach along five transects, which encompassed the twilight, transition, and deep zones; their results were compared to the results of other systematically applied techniques.…”

Ever-increasing human pressures on cave biodiversity have amplified the need for systematic, repeatable, and intensive surveys of cave-dwelling arthropods to formulate evidence-based management decisions. We examined 110 papers (from 1967 to 2018) to: (i) understand how cave-dwelling invertebrates have been sampled; (ii) provide a summary of techniques most commonly applied and appropriateness of these techniques, and; (iii) make recommendations for sampling design improvement. Of the studies reviewed, over half (56) were biological inventories, 43 ecologically focused, seven were techniques papers, and four were conservation studies. Nearly one-half (48) of the papers applied systematic techniques. Few papers (24) provided enough information to repeat the study; of these, only 11 studies included cave maps. Most studies (56) used two or more techniques for sampling cave-dwelling invertebrates. Ten studies conducted ≥10 site visits per cave. The use of quantitative techniques was applied in 43 of the studies assessed. More than onethird (42) included some level of discussion on management. Future studies should employ a systematic study design, describe their methods in sufficient detail as to be repeatable, and apply multiple techniques and site visits. This level of effort and detail is required to obtain the most complete inventories, facilitate monitoring of sensitive cave arthropod populations, and make informed decisions regarding the management of cave habitats. We also identified naming inconsistencies of sampling techniques and provide recommendations towards standardization.
