“…Broad-scale studies show that vegetation is a good biodiversity surrogate (Dobson et al 1997;Osborn et al 1999;Ricketts et al 1999), given its keystone character for a number of taxonomic groups dependent on vegetation (Peck 1989;Crisp et al 1998;Ferris & Humphrey 1999).…”

We examined six groups of taxa-woody plants, aquatic and terrestrial herpetofauna, small terrestrial birds, orchids, and Orthoptera-to determine their efficiency as biodiversity indicators in the Dadia Reserve in northern Greece. We investigated the indicator value of each group by examining the degree of congruence of its species-richness pattern with that of the other groups and the efficiency of its complementary network in conserving the other groups and biodiversity. The two techniques differed in many respects in their outputs, but they both showed woody plants as the best biodiversity indicator. There was in general low congruence in the species richness patterns across the different groups. Significant relationships were found between woody plants and birds, Orthoptera and terrestrial herpetofauna, and birds and aquatic herpetofauna. None of the optimal complementary networks of the groups we examined protected all species of the other groups. Nevertheless, the complementary network of woody plants adequately conserved all groups except orchids. We conclude that the principle of complementarity must be integrated into the methodology of evaluating an indicator. In an applied context, our results provide a scientific background on which to base a biomonitoring program for the Dadia Reserve. In a wider scope, if the group of woody plants prove an adequate biodiversity indicator for other Mediterranean areas as well, this will be important because it will facilitate conservation-related decisions for the entire Mediterranean region.Resumen: Examinamos seis grupos de taxones -plantas leñosas, herpetofauna acuática, herpetofauna terrestre, aves terrestres pequeñas, orquídeas y Orthoptera -para determinar su eficiencia como indicadores de biodiversidad en la Reserva Dadia en el norte de Grecia. Investigamos el valor de cada grupo como indicador examinando el grado de congruencia de su patrón de riqueza de especies con el de otros grupos y la eficiencia de su red complementaria para conservar a los otros grupos y a la biodiversidad. Las dos técnicas difirieron en muchos aspectos de sus resultados, pero ambos mostraron a las plantas leñosas como el mejor indicador de biodiversidad. Hubo poca congruencia en los patrones de riqueza de especies en los diferentes grupos. Se encontraron relaciones significativas entre plantas leñosas y aves, Orthoptera y herpetofauna terrestre, y aves y herpetofauna acuática. Ninguna de las redes complementariasóptimas de los grupos que examinamos protegió a todas las especies de los otros grupos.

Concluimos que se debe integrar el principio de complementariedad a la metodología para evaluar un indicador. En un contexto aplicado, nuestros resultados proporcionan un antecedente científico sobre el cual basar un programa de biomonitoreo para la Reserva Dadia.

“…However, there is considerable concern that single-taxon studies may not provide useful information for conservation planning .The few studies available suggest that correlations in richness and diversity among taxa are weak (Lawton et al, 1998;Barlow et al, 2007;Basset et al, 2008a,b). Particular indicator groups have different merits and it is unlikely that any single group will adequately represent the overall diversity (Kremen et al, 1993;Pearson, 1994;Brown, 1997;Osborn et al, 1999). For this reason, it is widely recommended that multiple taxa be included in such studies, especially if these have contrasting ecological roles and habitat specialisations (Kremen et al, 1993).…”

Abstract. 1. We carried out rapid assessments of the richness and diversity of fruitfeeding butterflies (sampled with baited traps) and dung beetles (sampled with buffalo dung-baited pitfall traps) at 20 sites across an anthropogenic forest disturbance gradient in Ba Be National Park, Vietnam.2. We investigated measures of diversity, richness, and functional composition for individual taxa in relation to the degree of disturbance, and verified whether dung beetles and butterflies showed congruent trends.3. For butterflies, overall species richness increased with forest disturbance, but the richness of rare species decreased. Species diversity was uncorrelated with disturbance.4. In dung beetles, species richness was unrelated to forest disturbance, but species diversity increased with forest disturbance. The richness of dung beetles in the telecoprid (roller) guild declined with forest disturbance.5. There was no significant correlation between dung beetles and butterflies across sites for either species richness or species diversity.6. Apparent effects of disturbance were thus sensitive to the particular metric used (species richness or diversity), the taxonomic group studied (butterflies or dung beetles), and the functional group investigated (different guilds of dung beetle).

“…Insects are abundant, varied and essential in terrestrial ecosystems as herbivores, pollinators, and as food and host organisms . In particular, Lepidoptera are extremely sensitive (Harper et al, 2000) and have already been used in different biogeographical and diversity studies on environmental pollution changes (Pöllänen, 1993) or in combined studies of biodiversity (Osborn et al, 1999;Hermy & Cornelis, 2000). This group responds quickly to changes in habitat regarding structure, botanical composition and fragmentation (Cappuccino & Martin, 1997;Zschokke et al, 2000).…”

Analysis of forestry impacts and biodiversity in two Pyrenean forests through a comparison of moth communities (Lepidoptera, Heterocera)

We have compared the biodiversity variations in moth communities between unmanaged forests and commercial forests in a mountainous environment (Pyrenees France). The aim was to evaluate the impact of forestry activities on moth diversity. The data collected from the insects were analysed with a Bayesian specific similarity index (noted SSP index) and by statistical biodiversity indexes comparison. It was seen that diversity and richness were decreased in the plantation compared to the unmanaged forest. Interestingly, the composition of the communities of moths was shown to be not only related to the presence/absence of host plants, but also to be in relation with changes in the differences in forest architecture (i.e. the relative coverage by the different vegetation levels). However, the moth community in the commercial forest still has a high capacity to converge with the moth community present in more natural forests. We report here a list of 177 species of moths, providing information on the distribution of some uncommon species, poorly studied as yet in the Pyrenees.
