“…In Victoria (Australia), stream classifications based on aquatic macro-invertebrates showed similar results for family, genus and species level data (Hewlett 2000). Likewise, the discriminatory power of oribatid mites in a Mediterranean area for pollution and fire disturbance was similar at the levels of family, genus and species (Caruso and Migliorini 2006). In contrast to these findings, however, several other studies indicate that the species level is most appropriate for biological monitoring.…”

“…The diversity and composition of terrestrial arthropod communities have widely been used as bio-indicators for a variety of processes and habitat characteristics, including vegetation properties, river flooding regime, land use and management practices, ecosystem restoration, and soil contamination (e.g., Basset et al 2004;Cartron et al 2003;Gardner 1991;Irmler 2003). However, because of the large abundance and richness, considerable time and taxonomic expertise are required for sorting terrestrial arthropods samples and identifying individuals to the species level (Basset et al 2004;Caruso and Migliorini 2006;Gardner et al 2008;Lawton et al 1998;Moreno et al 2008). Common alternatives proposed to reduce time and economic efforts include shortening the sampling period (Biaggini et al 2007;Caruso and Migliorini 2006), using morpho-species (Basset et al 2004), selecting specific indicator species (Beccaloni and Gaston 1995), and using data of higher taxonomic levels as surrogates for species (Andersen 1995).…”

Four arthropod datasets of different taxonomic detail were compared on their discriminatory power for various environmental characteristics in a lowland floodplain area along the river Rhine. The arthropod datasets comprised ground-dwelling arthropods at class-order level (n = 10), beetle families (n = 32), ground beetle genera (n = 30) and ground beetle species (n = 68). Environmental characteristics included vegetation characteristics, hydro-topographic setting, physical-chemical soil properties and soil contamination levels. Relations between arthropod assemblages and environmental factors were assessed with variance partitioning: a multivariate statistical approach that attributes variation in community composition to specific explaining variables. The variance partitioning showed comparable results for the four datasets. A substantial part of the variation (31-38%) could be ascribed to vegetation characteristics. Variance could further be attributed to physical-chemical soil properties (7-10%), hydro-topographic setting (3-7%) and soil metal contamination (2-4%). Thus, in strongly heterogeneous landscapes like lowland river floodplains, relatively coarse taxonomic data can already provide a valuable indication of the relative importance of different environmental factors for structuring arthropod communities. However, the ground beetles showed a higher specificity for different vegetation types and a more distinct relation to soil contamination levels than the other arthropod datasets. Hence, a higher degree of taxonomic detail will be beneficial for investigating the consequences of for example environmental pollution or vegetation characteristics in terms of taxonomic diversity or community composition.

“…Detritivorous microarthropods also provide food for predator mites (Cluzeau et al, 2012;Paoletti et al, 2007;Caruso and Migliorini, 2006). Indeed, the positive correlation (R 2 = 0.54) which was observed between the number of predator (gamasid mites) and detritivorous (oribatid mites and springtails) highlights the influence of the trophic level on the distribution of microarthropod communities.…”

While the effects of metal(loid)s on vegetation and macrofauna have been widely studied, their impact on microarthropods (millimetre scale) and their bioaccumulation capacity have been less investigated. However, microarthropods provide important ecosystem services, contributing in particular to soil organic matter dynamics. This study focussed on the impact of metal(loid) pollution on the structure and distribution of microarthropod communities and their potential to bioaccumulate lead (Pb). Soil samples were collected from a contaminated historical site with a strong horizontal and vertical gradient of Pb concentrations. Microarthropods were extracted using the Berlese method. The field experiments showed that microarthropods were present even in extremely polluted soils (30,000 mg Pb kg −1 ). However, while microarthropod abundance increased with increasing soil C/N content (R 2 = 0.79), richness decreased with increasing pollution. A shift in the community structure from an oribatid-to a springtail-dominated community was observed in less polluted soils (R 2 = 0.68). In addition, Pb bioamplification occurred in microarthropods, with higher Pb concentrations in predators than in detritivorous microarthropods. Finally, the importance of feeding and reproductive ecological traits as potentially relevant descriptors of springtail community structures was highlighted. This study demonstrates the interest of microarthropod communities with different trophic levels and ecological features for evaluating the global environmental impact of metal(loid) pollution on soil biological quality.

“…Desde entonces, se han sumado investigaciones que abarcan distintos grupos de artrópodos terrestres, ecosistemas y perturbaciones antrópicas (Pik et al, 2002;Caruso & Migliorini, 2006;Biaggini et al, 2007;Uehara-Prado et al, 2009;Groc et al, 2010;Bang & Faeth, 2011). Un reciente meta-análisis de estudios de biodiversidad de artrópodos en Canadá (Timms et al, 2013) sugiere que la suficiencia taxonómica debería aplicarse a la resolución taxonómica de género y cuando la proporción taxonómica sea baja, es decir si las familias o los géneros incluyen pocas especies.…”

ResumenLa suficiencia taxonómica ha recibido creciente atención en estudios sobre el monitoreo de los efectos de perturbaciones en comunidades de artrópodos terrestres. El objetivo principal fue probar que la estructura comunitaria de artrópodos epígeos analizada a distintas resoluciones taxonómicas puede distinguir los ecosistemas en estudio. Los artrópodos epígeos fueron colectados con trampas de caída en seis ecosistemas del desierto costero peruano, en la provincia de Pisco (Ica, Perú). La capacidad de distinguir los ecosistemas fue comparada entre órdenes, familias y especies, utilizando tres tipos de análisis multivariados (NMDS, cluster, ANOSIM) y tres índices de similitud (Raup-Crick, Bray-Curtis, Morisita-Horn). Asimismo, se realizaron análisis adicionales para caracterizar las matrices de datos y, medir la relación de la estructura comunitaria con el principal gradiente ambiental (aridez). Los resultados fueron: 1) la estructura comunitaria de artrópodos epígeos analizada a distintas resoluciones taxonómicas distinguió los ecosistemas incluidos en el área de estudio; 2) la agregación de las matrices de datos es un proceso que mejora la aplicación de los análisis multivariados; 3) la estructura comunitaria de artrópodos epígeos analizada a distintas resoluciones taxonómicas estuvo relacionada al principal gradiente ambiental del área de estudio. Estos resultados fueron comparados con los hallazgos de estudios previos y se formulan algunas sugerencias para estudios futuros. Palabras clave: artrópodos epígeos, estructura comunitaria, suficiencia taxonómica, índices de similitud, monitoreos biológicos, datos multivariados. AbstractTaxonomic sufficiency has received increasing attention in studies aimed at monitoring the effects of disturbances on terrestrial arthropod communities. The main objective was to prove that the community structure of epigaeic arthropods analyzed at different taxonomic resolutions can distinguish the ecosystems studied. Epigaeic arthropods were sampled with pitfall traps in six Peruvian coastal desert ecosystems in the province of Pisco (Ica, Peru). The ability to distinguish ecosystems was compared among orders, families and species, using three types of multivariate analyzes (NMDS, cluster, ANOSIM) and three similarity indexes (Raup-Crick, Bray-Curtis, Morisita-Horn). Also, additional analyses were performed to characterize the data matrices and to measure the relationship of community structure with the main environmental gradient (aridity). The results were: 1) the community structure of epigaeic arthropods analyzed at different taxonomic resolutions distinguished ecosystems included in the study area, 2) the aggregation of data matrices is a process that improves the application of multivariate analysis, 3) the community structure of epigaeic arthropods analyzed at different taxonomic resolutions was related to the main environmental gradient in the study area. These results are compared with findings from previous studies and some suggestions for future studies are made.
