“…The characteristic species is defined as the most characteristic species of each habitat type, found mostly in that habitat and present in the majority of sites belonging to that habitat. This proved to be a useful method to identify the characteristic invertebrate species in several habitats [4,22,23].…”

Responses of isopod assemblages to urbanisation were studied along an urbanesuburbanerural gradient representing a decrease in the intensity of human disturbance. Pitfall trapping collected six species (Armadillidium vulgare, Porcellio scaber, Porcellium collicola, Trachelipus ratzeburgii, Cylisticus convexus, and Trachelipus rathkii). A. vulgare occurred abundantly in all sites reflecting the broad tolerance and invasive nature of this species. Indicator species analysis demonstrated that P. scaber and T. rathkii were significant quantitative character species for the urban site, while T. ratzeburgii was characteristic for the natural habitats (suburban and rural sites). CANOCO revealed that ground and air temperature show positive correlation with the distribution of P. scaber and T. rathkii, and negative correlation with T. ratzeburgii. Nested ANOVA on trap level showed that there were no significant differences between the number of isopod species and individuals, and the diversity of isopod assemblages in the three studied areas. Significant differences were observed at site level. The results did not support the hypothesis that diversity should decrease in response to habitat disturbance. They also contradicted the intermediate disturbance hypothesis; species richness was not the highest in the moderately disturbed suburban area. Multivariate methods detected that the isopod assemblages of the rural and suburban areas were relatively similar, while that of the urban area was relatively separated.

“…In general, conifer plantations are considered low-diversity ecosystems (Peterken 1996;Cannell 1999) as compared to native mature forests (e.g. for carabid beetles: Fahy and Gormally 1998;Elek et al 2001;Magura et al 2002). However, the low structural heterogeneity of plantations can evolve due to the ageing process or management practices, progressively leading to a more diversified structure of the planted trees (Kint 2005), resembling that of natural deciduous forests, and, consequently, increasing variability of tree characteristics and the forest diversity (see Barbier et al 2008).…”

Plant and carabid beetle species diversity in relation to forest type and structural heterogeneity

et al. 2008

The aim of this study was to evaluate the influence of forest structure (mainly resulting from human uses) and forest type (the identity of the dominant tree species) on biodiversity. We determined the diversity of two taxonomical groups: the understory vegetation and the edaphic carabid beetle fauna. We selected eight types of forest ecosystems (five replicates or stands per forest type): pine (Pinus sylvestris) plantations of three age classes (10, 40 and 80 years since reforestation), an old-growth relict natural pine forest, and four types of oak (Quercus pyrenaica) stands: mature forests with livestock grazing and firewood extraction, mature forests where uses have been abandoned, ''dehesa'' ecosystems and shrubby oak ecosystems. The results obtained by a global PCA analysis indicated that both tree size and dominant species influenced the ordination of the 40 forest stands. In general, carabids were more sensitive to changes in forest heterogeneity and responded more clearly to the analysed structural variables than the understory vegetation, although the species richness of both groups was significantly correlated and higher in case of oak forests. Pine forest ecosystems were characterised by the lowest species richness for both taxonomical groups, the lowest plant diversity and by the lowest coefficients of variation and, consequently, low structural heterogeneity. As a result, it was very difficult to discriminate the effects of the spatial heterogeneity and the dominant tree species on biodiversity.

“…Baguette and Gérard (1993) found that the species composition and richness of carabid communities in spruce plantations differed significantly among the studied age classes. On the contrary for Elek et al (2001), abundance and species richness did not present significative differences among spruce plantations of different ages.…”

“…The indicator value (IndVal) was applied to find characteristic species (Elek et al, 2001) and species assemblages characterising the "MF", "BE", "HO", "MP" and "PR" plantations. The novelty of this approach lies in the way it combines a species relative abundance to its relative frequency of occurrence in the groups of samples.…”

Abstract• Carabid beetles were investigated at five different forest types in the Ibaizabal basin (northern Spain). The landscape is characterized by the presence of remnants of native forest surrounded by conifer plantations.• Carabids were trapped in 52 stands of mixed forest, beech forest, holm oak forest, mixed pine and Monterey pine plantations in 2005 and 2006. The main objectives of the study were: compare carabid diversity, recognise the characteristic species, and study the effects of ecological variables on carabid assemblages in the different forest types.• No significative differences in species abundance, richness and diversity were found among the studied forests. Most of the trapped beetles were identified as forest generalists, nevertheless some native and non-native forest specialist species were also found. Distribution of carabid communities overlapped and, except for beech forest, no specific communities were distinguished. Altitude, percentage of grass coverage and temperature were the main variables influencing species distribution.• The results suggest high habitat homogeneity, caused by regeneration in pine plantations of the indigenous understorey, and by poor habitat quality in native forest (patchy remnants enclosed in conifer plantations). This situation could explain the similar carabid diversity.

Le paysage est caractérisé par la présence de vestiges de la forêt naturelle entourés par des plantations de conifères.• Les carabidés ont été piégés en 2005 et 2006, dans 52 peuplements de forêts mixtes, hêtraies, chê-naies vertes, peuplement mélangé de pins et plantations de pins de Monterey. Les principaux objectifs de l'étude ont été : la comparaison de la diversité des carabidés, la reconnaissance des espèces caractéristiques, et l'étude des effets des variables écologiques sur les assemblages de carabidés dans les différents types de forêts.• Parmi les forêts étudiées, il n'a pas été mis en évidence de différences significatives pour ce qui concerne l'abondance des espèces, la richesse et la diversité. La plupart des coléoptères piégés ont été identifiés comme étant des généralistes des forêts, néanmoins certaines espèces autochtones et non autochtones des forêts ont également été trouvées. Les répartitions des communautés de carabidés se chevauchent et, à l'exception des hêtraies, aucune communauté spécifique n'a été distinguée. L'altitude, le pourcentage de couverture herbacée et la température ont été les principales variables qui ont influencé la répartition des espèces.• Les résultats obtenus suggèrent que la haute homogénéité de l'habitat est causée par la régénération d'un sous-bois d'espèces ...
