Climate change threatens the health and survival of urban trees and the various benefits they deliver to urban inhabitants. Here, we show that 56% and 65% of species in 164 cities across 78 countries are currently exceeding temperature and precipitation conditions experienced in their geographic range, respectively. We assessed 3,129 tree and shrub...

Urban forests (i.e. all vegetation present in urban areas), provide environmental and socio-economic benefits to more than half of the global population. Projected climate change threatens these benefits to society. Here, we assess vulnerability to climate change of 16,006 plant species present in the urban forests of 1,010 cities within 93 countri...

Article
Aim Climate warming reshuffles biological assemblages towards less cold‐adapted but more warm‐adapted species, a process coined thermophilization. However, the velocity at which this process is happening generally lags behind the velocity of climate change, generating a climatic debt the temporal dynamics of which remain misunderstood. Relying on h...

This study presents the assemblage of an exhaustive reference library for one of the major groups of soil invertebrates, earthworms, focused on the long sampled French location of Upper Normandy. Previous morphological appraisal of the diversity, enumerated 20 species in the area. After an extensive campaign of DNA barcoding aiming at several typic...

Palatable exotic shrubs plantation in heavily degraded rangeland has been massively managed in arid and semi-arid Algeria. An associated effect observed to these managements is an increase of plant richness in these plantations due to positive interactions involving nurse species that ameliorate stressful environmental conditions. Our objective was...
Article
Description du sujet. Ces quatre dernières décennies ont été marquées par la lutte contre la désertification et la protection des écosystèmes steppiques, devenues des priorités en Algérie. Plusieurs modalités de restauration ont été retenues pour gérer, voire restaurer les parcours steppiques sensibles. Objectifs. L’étude menée vise à quantifier l’...
Conference Paper
Full-text available
Trends in species diversity represent an important challenge to be addressed by forest monitoring in response to environmental changes, of which climate is critical. However assessing such changes faces methodological issues. Useful lessons can be drawn from practical experience. In France, forest ecosystems have been intensively monitored since 19...
Article
The limited dispersal ability of earthworms is expected to result in marked genetic isolation by distance and remarkable spatial patterns of genetic variation. To test this hypothesis, we investigated, using microsatellite loci, the spatial genetic structure of two earthworm species, Allolobophora chlorotica and Aporrectodea icterica, in two plots...

Biological invasions are increasingly rec-ognized as a potent force altering native ecosystems worldwide. Many of the best documented cases involve the massive invasions of North America by plant and animal taxa native to Europe. In this study, we use DNA barcoding to survey the occurrence and genetic structure of two major groups of soil inverte-b...
Article
Studying spatial patterns of soil engineers has become an important issue that may contribute to a better understanding of soil functioning. We investigated the spatial patterns of earthworm species assem-blages in a recently settled and an old temperate pasture. Earthworms were sampled following a spatially explicit sampling design. Data were anal...
Conference Paper
Full-text available
Background/Question/Methods It has been largely shown that the modification of soil properties through the action of earthworms has indirect consequences on plant growth. Some studies also suggest that earthworms could have a direct impact on seed germination and plant seedling growth through their ingestion and rejection of seeds within their nut...
Article
The taxonomic status of Allolobophora chlorotica is still the subject of considerable discussion. After the recent experimental demonstration that the two regularly observed colour morphs (pink and green) were not fully interfertile and likely represent two distinct species, molecular analyses revealed a more complex picture with the occurrence of...

The widely studied and invasive earthworm, Lumbricus terrestris L., 1758 has been the subject of nomenclatural debate for many years. However these disputes were not based on suspicions of heterogeneity, but rather on the descriptions and nomenclatural acts associated with the species name. Large numbers of DNA barcode sequences of the cytochrome o...
Article
Species identification of earthworms is usually achieved by careful observation of morpho-logical features, often sexual characters only present in adult specimens. Consequently, juve-niles or cocoons are often impossible to identify, creating a possible bias in studies that aim to document species richness and abundance. DNA barcoding, the use of...

The biodiversity of soil communities remains very poorly known and understood. Soil biological sciences are strongly affected by the taxonomic crisis, and most groups of animals in that biota suffer from a strong taxonomic impediment. The objective of this work was to investigate how DNA barcoding – a novel method using a microgenomic tag for speci...

Project
This projet aims at valuing the data coming from the monitoring of the Renecofor network (102 plots in french forests). These plots have been surveyed first in 1995, then each 5 years.

This project focused on earthworm dispersal. We tackled questions such as - How far can earthworm disperse with their own movements (active dispersal) - Do they "decide" do disperse and when? In particular is there any link with conspecific density or habit use? - How fast can they recolonize new habitat? We used a combination of field work, landscape genetic, capture recatpure, lab experiments and dynamic modeling to tackle this topic. The funding is over but we still have a few experiments to publish. (How doesn't! :-) ) The project was funded by an ANR Jeune Chercheur coordinated by Jérôme Mathieu
