Abstract.A major challenge confronting many contemporary systematists is how to integrate standard taxonomic research with conservation outcomes. With a biodiversity crisis looming and ongoing impediments to taxonomy, how can systematic research continue to document species and infer the 'Tree of Life', and still maintain its significance to conservation science and to protecting the very species it strives to understand? Here we advocate a systematic research program dedicated to documenting short-range endemic taxa, which are species with naturally small distributions and, by their very nature, most likely to be threatened by habitat loss, habitat degradation and climate change. This research can dovetail with the needs of industry and government to obtain high-quality data to inform the assessment of impacts of major development projects that affect landscapes and their biological heritage. We highlight how these projects are assessed using criteria mandated by Western Australian legislation and informed by guidance statements issued by the Environmental Protection Authority (Western Australia). To illustrate slightly different biological scenarios, we also provide three case studies from the Pilbara region of Western Australia, which include examples demonstrating a rapid rise in the collection and documentation of diverse and previously unknown subterranean and surface faunas, as well as how biological surveys can clarify the status of species thought to be rare or potentially threatened. We argue that 'whole of biota' surveys (that include all invertebrates) are rarely fundable and are logistically impossible, and that concentrated research on some of the most vulnerable elements in the landscape -short-range endemics, including troglofauna and stygofauna -can help to enhance conservation and research outcomes.

“…At the moment, it seems difficult or even impossible to identify the affiliation of hyporheic species to functional groups. For example, Boulton et al (2008) hypothesized that stygobiotic amphipods were shredders similar to their surface water relatives, but recent findings suggest that they are deposit feeders. The hypogean Niphargus rhenorhodanensis use the fecal pellets and fine detritus produced by epigean Gammarus roeselii when shredding leaf litter .…”

-Fifty years after the hyporheic zone was first defined (Orghidan, 1959), there are still gaps in the knowledge regarding the role of biodiversity in hyporheic processes. First, some methodological questions remained unanswered regarding the interactions between biodiversity and physical processes, both for the study of habitat characteristics and interactions at different scales. Furthermore, many questions remain to be addressed to help inform our understanding of invertebrate community dynamics, especially regarding the trophic niches of organisms, the functional groups present within sediment, and their temporal changes. Understanding microbial community dynamics would require investigations about their relationship with the physical characteristics of the sediment, their diversity, their relationship with metabolic pathways, their interactions with invertebrates, and their response to environmental stress. Another fundamental research question is that of the importance of the hyporheic zone in the global metabolism of the river, which must be explored in relation to organic matter recycling, the effects of disturbances, and the degradation of contaminants. Finally, the application of this knowledge requires the development of methods for the estimation of hydrological exchanges, especially for the management of sediment clogging, the optimization of self-purification, and the integration of climate change in environmental policies.

Resumo. Na área cárstica da Serra da Bodoquena ocorrem cavernas inundadas e submersas, além de cavernas secas, que abrigam uma fauna troglóbia importante. Cinco espécies de siluriformes trogló-bios são atualmente conhecidas nesta região: Ancistrus formoso (Loricariidae), Trichomycterus dali (Trichomycteridae) e três espécies ainda não descritas, Ancistrus sp. (Loricariidae), Rhamdia sp. (Heptapteridae) e Trichomycterus cf. dali. Considerando que a compreensão dos padrões ecológicos, biológicos e biogeográficos é necessária para a elaboração de ações eficazes para a preservação dos ecossitemas subterrâneos, são apresentados os resultados parciais do estudo de populações das três espécies não descritas. A ampliação das áreas de preservação a fim de abrangerem todas as áreas de ocorrência dos peixes troglóbios na Serra da Bodoquena é sugerida. Palavras-chave. Ictiofauna; Água subterrânea; Monitoramento; Populações; Conservação.Abstract. In Bodoquena karst area occur large submerged and flooded cave systems, as well as dry caves, which harbor an important troglobitc fauna. Five troglobitic species of Siluriformes are currently known: Ancistrus formoso (Loricariidae), Trichomycterus dali (Trichomycteridae), and three undescribed species, Ancistrus sp. n. (Loricariidae), Rhamdia sp.n. (Heptapteridae) and Trichomycterus cf. dali. Due the need of understanding the ecological, biological and biogeographic processes for the development of effective actions on conserve the subterranean ecosystems, partial results of population studies of the three undescribed species are presented. The expansion of conservation areas in order to cover all the occurrence areas of troglobitic fishes in Bodoquena Plateau is suggested. Keywords.

Os sistemas subterrâ-neos (ou hipógeos) compreendem conjuntos interconectados de cavidades, fendas e fraturas na rocha, preenchidos por água e/ou ar, podendo ocupar grandes volumes no interior de maciços rochosos (Palmer, 2007).Os troglóbios são animais que habitam exclusivamente os ecossistemas subterrâneos, sendo, em geral, reconhecidos pela redução até ausência de olhos e de pigmentação melânica (troglomorfismos clássicos). Outras especializações que podem estar presentes nestes animais incluem: baixa densidade populacional, distribuição geográfica restrita, tendência à estratégia de vida do tipo K e baixa tolerância a estresse ambiental (Trajano, 2000). Essas características fazem dos troglóbios animais potencialmente em ameaça de extinção, pois tendem a ser sensíveis às alterações ambientais em seus hábitats e suas populações podem apresentar baixa capacidade de repor indivíduos (Trajano, op. cit.). Além disso, entre os táxons troglóbios podem ocorrer relictos biogeográficos importantes, cuja distribuição, em alguns casos, remete à...
