TLDR
Although indicator taxa are considered to be generally unreliable as broad indicators of biodiversity, they may serve a useful function in identifying ecological characteristics or monitoring the effects of habitat management.Abstract:
Bioindicators, as taxa or functional groups, are widely used as indicators of environmental change, specific ecological factors or taxonomic diversity. The use of ecological, environmental and biodiversity indicators, is reviewed here. Although indicator taxa are considered to be generally unreliable as broad indicators of biodiversity, they may serve a useful function in identifying ecological characteristics or monitoring the effects of habitat management. Use of only a narrow range of taxa may be unreliable, and is particularly vulnerable to distortion by a small number of invasive species. Taxa also need to be selected to reflect the specific ecosystem being studied. It is recommended that isopods be used for soil systems (if there is sufficient local diversity), in some areas earthworms or mites may be useable but are generally too difficult to identify to be practically useful. In the ground layer indicator sets could include ants, millipedes, molluscs (snails in particular), ground beetles, harvestmen and gnaphosid spiders. Foliage-inhabiting indicators could comprise ants, chrysomelid leaf beetles, theridiid spiders and arctiid moths. Ants, orthopterans and butterflies may be appropriate for use in open habitats. These basic sets should be supplemented by other taxa where appropriate resources and taxonomic expertise are available.read more

Dung beetles as indicators of tropical forest restoration success: Is it possible to recover species and functional diversity?
TL;DR: While restored areas have the capacity to host forest-restricted species, 18 years since active restoration has not been long enough to recover a stable and diverse dung beetle assemblage, this study demonstrates that measures of composition, species diversity and functional diversity can complement each other and contribute to a better understanding of the efficacy of restoration practices.

TL;DR: This paper aims to compare, review and discuss the strengths and limitations of four general implementation strategies of environmental genomics for monitoring, and proposes a roadmap for the implementation of environmentalgenomics into routine monitoring programmes that leverage recent analytical advancements.

Neotropical dragonflies (Insecta: Odonata) as indicators of ecological condition of small streams in the eastern Amazon
José Max Barbosa Oliveira-Junior,José Max Barbosa Oliveira-Junior,Yulie Shimano,Toby A. Gardner,Robert M. Hughes,Paulo De Marco Júnior,Leandro Juen +6 more
TL;DR: An assessment of this low-order Amazonian stream system concludes that dragonflies and other insects can act as useful indicators of the ecological consequences of riparian habitat loss and disturbance and preserving dense riparian vegetation is necessary to maintain aquatic ecological condition.

Species assemblages and indicator species:the need for a flexible asymmetrical approach

TL;DR: A new and simple method to find indicator species and species assemblages characterizing groups of sites, and a new way to present species-site tables, accounting for the hierarchical relationships among species, is proposed.

Ten species in one: DNA barcoding reveals cryptic species in the neotropical skipper butterfly Astraptes fulgerator
TL;DR: The results add to the evidence that cryptic species are prevalent in tropical regions, a critical issue in efforts to document global species richness, and illustrate the value of DNA barcoding, especially when coupled with traditional taxonomic tools, in disclosing hidden diversity.

Flagships, umbrellas, and keystones: Is single-species management passé in the landscape era?
TL;DR: The recognition that some ecosystems have keystone species whose activities govern the well-being of many other species suggests an approach that may unite the best features of single-species and ecosystem management.

Rare species, the coincidence of diversity hotspots and conservation strategies
TL;DR: In this paper, the authors examined the extent to which species-rich areas for different taxa coincide and whether rare species occur in, and therefore benefit from the conservation of, species rich habitats.
