Expérimentarium - Alice au pays des carabes

2016

Rien de tel que les gestes du dessinateur pour faire vivre les gestes du chercheur. Thibault Roy, Marie-Laure Baudement et Jo-Ann Campion ont rencontré des doctorants de toutes disciplines afin d’échanger sur leurs pratiques. Ces dessins illustrent ces rencontres et ces échanges. La Mission Culture Scientifique protège et valorise les collections scientifiques et techniques. Ces collections participent à la recherche et à sa valorisation. Ce sont des ressources irremplaçables pour la science et l’avancement des connaissances dans de nombreux domaines tels que le changement climatique, l’écologie et l’évolution des systèmes vivants, la géologie, l’archéologie, l’ethnologie, l’anthropologie, …

L’organisation spatiale du paysage : un levier d’action pour promouvoir le service de prédation des graines d’adventices par les carabidés ?

2014

National audience; Le contexte actuel engage à développer une agriculture durable et entre autres de favoriser des services écosystémiques comme la régulation biologique des bio-agresseurs par des auxiliaires de cultures. Parmi les processus impliqués dans ces régulations biologiques, la prédation des graines d’adventices par les coléoptères carabidés opère de façon générique dans les parcelles cultivées et peut être considérée comme un service écosystémique. Elle résulte de l’action de certaines espèces ‘granivores’ spécialistes souvent peu abondantes dans les champs ainsi que de l’action d’espèces omnivores pour lesquelles les graines d’adventices peuvent représenter une ressource alterna…

Influence du colza et des prairies à différentes échelles spatiales sur l’abondance des carabes prédateurs de graines d’adventices

2014

National audience; Les coléoptères carabidae sont très représentés dans les cultures annuelles où ils peuvent contribuer au contrôle biologique de bioagresseurs. Ainsi, les carabes omnivores et granivores consomment des quantités importantes de graines de plantes adventices. Des études récentes suggèrent que la réponse des communautés de carabes à l’organisation du paysage est en partie dépendante de leur guilde trophique. Néanmoins, dans le cas de carabes consommateurs de graines d’adventices, on connait peu les types d’occupation du sol qui les favorisent au sein d’un paysage et l’échelle spatiale à laquelle ces insectes répondent. Ici, nous avons analysé les variations de l’abondance de …

Un état des connaissances sur la prédation des graines adventices par les invertébrés

2013

Adopting agro-ecological management in farming systems requires a good knowledge of the different organisms that interact within the agorecosystem. Research on weed seed predation by invertebrates (Coleoptera, Adephaga, Carabidae) is booming. Here, we present an overview of current available knowledge on this ecosystem service and factors that may be important to enhance it.

Spatio-temporal dynamics of weed seed eating carabid species in agricultural mosaics: variation of annual habitat quality of oil seed rape and role o…

2017

National audience; Carabid beetles are considered as important contributors to the regulation of weeds and recent studies have shown that weed seed predation by carabids may partly substitute for herbicide use in agriculture. Enhancing this ecosystem service requires to understand the spatio-temporal distribution of these species during the cropping season. Infra-annual variation in the spatial distribution of ground beetles within agricultural mosaics is less documented but of prime importance given that agricultural landscapes are highly dynamics. Indeed, crop phenology, agricultural operations but also habitat requirements during life cycle can lead to a redistribution of individuals bet…

Effects of undergrowth removal and edge proximity on ground beetles and vascular plants in urban boreal forests

2019

Urban forests are regularly managed for human safety and esthetic reasons, but they are crucial habitat for many species. Removals of undergrowth occur commonly in these forests, yet the ecological consequences of these operations are poorly understood. We sampled ground beetles (Coleoptera, Carabidae) and vascular plants along 20-m edge gradients in Finnish urban forests, in five stands treated 0.5–2.5 years earlier with undergrowth removal and in five untreated stands. We hypothesized that undergrowth removal and edge proximity would benefit opportunistic and open-habitat species, whereas shady-habitat species would be affected negatively. (1) Regarding carabids, diversity and evenness in…

Hybridization, developmental stability, and functionality of morphological traits in the ground beetle Carabus solieri (Coleoptera, Carabidae).

2006

Correspondance.: stephane.garnier@u-bourgogne.fr; International audience; The assessment of developmental stability in hybrids can provide valuable information in the study of species formation because it allows an evaluation of the degree of incompatibility of genetic systems that control developmental processes. The present study assessed the impact of two hybridization events, assumed to have occurred at different times, on developmental instability in the ground beetle Carabus solieri . Developmental instability was estimated in 678 individuals from 27 populations from the fluctuating asymmetry (FA) levels of four morphological traits: the tibia length of middle and hind legs, which are…

Molecular and biometric data on Carabus (Macrothorax) morbillosus Fabricius, 1792 (Coleoptera, Carabidae) from Mid Mediterranean areas

2022

The present study was carried out using molecular and biometric data of Carabus (Macrothorax) morbillosus from mid-Mediterranean areas to determine additional information on basal relationships among its representative subspecies. To this aim, two different kinds of approach were employed, including a morphometric analysis of four morphological parameters (i.e., elytra length, elytra width, pronotum length, pronotum width) of 128 specimens, and a Bayesian genetic analysis of 44 cytochrome oxidase subunit I (COI) partial sequences (i.e., 38 examined for the first time and six retrieved from GenBank database). Representative populations of C. (M.) morbillosus were sampled in four countries, n…
