“…The families Carabidae and Staphylinidae were amongst the seven prominent ones in olive orchards in Granada Spain, but in very lower percentages (4% and 1% respectively of the Coleoptera total) than in this work (Cotes et al 2009b). The same families plus two (Tenebrionidae, Anthicidae) were the most abundant in olive groves in Granada and Cordova (Cotes et al 2009a). In Petrokefali region these families are especially dominant and for this reason its olive orchards have the lowest biodiversity, as Staphylinidae plus Carabidae reach percentages of 82.4% in the organic olive orchard of Petrokefali.…”

In this study the results of the captured Coleoptera in pitfall traps in nine olive orchards in the valley of Messara, on Crete Island, were compared. The liquid used for killing and preservation in the pitfall traps, was propylene glycol. The nine olive orchards were distributed in four areas in the valley. In each area there were at least two olive orchards under different agricultural management system, organic and conventional. The experiments were conducted from October 2004 to April 2005. The number of captured Coleoptera specimens was 4,937. The specimens were identified to the family level. Coleoptera from 25 families were found, but the analysis was focused at eleven of them, the richest in specimens. These were: Anthicidae, Carabidae, Chrysomelidae, Curculionidae, Histeridae, Leiodidae, Scarabaeidae, Silphidae, Silvanidae, Staphylinidae and Tenebrionidae. Staphylinidae were the most abundant in all olive orchards independently of the agricultural management (production system). In the other families instead of differences amongst the different systems of agricultural management, more prominent were the differences amongst areas.

“…The sampling was conducted in the pre‐blooming period (middle of May) in 2014, when many arthropods are particularly active and abundances show the greatest differences across farming systems (Ruano et al ., ; Cotes et al ., ). Specimens in the larvae phase of Lepidoptera and in the nymph phase of Homoptera were counted but excluded from statistical analysis as a result of difficulty in classifying correctly in families.…”

1 Agricultural intensification has greatly affected biodiversity in recent decades. One common and recent transformation that has taken place in Mediterranean countries is olive grove intensification, although its effects on biodiversity have rarely been studied. 2 In the present study, we investigated the effect of soil management practices, with versus without soil cover crops, on the arthropod abundance, richness, diversity and species composition in Andalusia olive groves, South Spain. 3 The results obtained show that these soil cover crops positively affect the diversity of arthropods, along with other variables such as the diversity of the plant community and Shannon index of the landscape. By contrast, the number of arthropods was higher in olive groves with bare ground as a result of the abundance of two families (Entomobryidae and Aeolothripidae), which comprised more than 50% of all the individuals collected. 4 Rank abundance diagrams and multivariate analyses showed differences between the two types of soil management systems with respect to the composition of families. 5 In conclusion, soil cover crops strongly improve the diversity of arthropods in olive orchards, which helps to maintain biodiversity in these intensive agroecosystems at the same time as improving other ecosystems services, such as soil fertility and the prevention of soil erosion.

“…En investigaciones recientes se ha observado que las variables ambientales (vegetación, edáficas, hídricas etc.) responsables de la distribución espacial de las comunidades de artrópodos epígeos tuvieron la misma jerarquía de importancia para diferentes resoluciones taxonómicas (Cotes et al, 2010;Schipper et al, 2010). En estos casos, el grado de heterogeneidad ambiental es tan marcado que no sólo sobrepasa la capacidad de tolerancia de las especies, sino también la tolerancia de los taxones de alto rango.…”

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.
