Focus on the Odonata fauna of Saül, a small town in the amazonian forest.

On July 2014, a teneral specimen of an unknown Micrathyria species was found during the survey of an open marsh in Trou-Poissons in the coastal savannah of French Guiana. Further specimens were subsequently collected at the same place and at two other localities in Kourou and Macouria. The male and female of this new species are described here. Mic...

Insect larval development affects adult traits but the biometric relationships are usually poorly understood, including large odonates. In this study, measurements of morphological traits of larvae, exuviae and adults of Anax imperator were recorded. They were used to investigate the effects of early development on adult morphology. Results showed...

1. Local movements of aquatic insects within the surroundings of waterbodies aim essentially to find food, mates, resting sites, or avoid predation. Distances moved are very variable among species and may also differ depending on sex or age at the intraspecific scale. Despite a large panel of studies on odonate activities near wa-terbodies, little...

Ponds are lentic waterbodies with a high conservation value for biodiversity that have long been overlooked by management policies. Recent initiatives aimed to promote the conservation of these ecosystems by restoring or creating new ponds throughout Europe. Therefore, studying responses of aquatic invertebrates to local pond characteristics and co...

This publication documents the diversity of odonates found in French Guiana and discusses their distribution and ecology. The checklist was created by compiling information from available publications and databases. A total of 292 species belonging to 14 families and 94 genera are listed from the territory. Of these, one family, three genera and 48...

Anthropogenic activities cause loss and fragmentation of natural habitats and have strong effects on population maintenance by increasing their isolation. Pond ecosystems are scattered waterbodies that can interact as a network connected by dispersal events of freshwater organisms. Identifying local genetic differentiations and understanding how ge...

Au cours des dernières décennies, le nombre de mares a connu un déclin de plus de 50 % dans les pays européens, atteignant parfois jusqu'à 90 % dans certaines régions. Cette diminution a entraîné une forte perte de connectivité entre les mares. Pourtant, ces écosystèmes petits et dispersés sont essentiels au cycle de vie d'une grande diversité d'es...

Les technologies actuelles de télémétrie permettent d’équiper les plus grosses libellules de radio-émetteurs afin de suivre leurs déplacements. Nous avons étudié les capacités de dispersion d’Anax imperator ainsi que l’utilisation de son habitat en Normandie. Pendant l’été 2017, 41 individus ont été équipés de radio-émetteurs d’environ 0,25 g et 9...

After the restoration of peatlands which were previously exploited in two valleys, the dragonfly Leucorrhinia pectoralis settled down in the swiss Jura. This species listed at the second annexe of the Bern Convention is critically endangered in Switzerland. As part of a 5 years populations study, this work enabled to estimate the size of the bigges...
