Passive rewilding is increasingly seen as a promising tool to counterbalance biodiversity losses and recover native forest ecosystems. One key question, crucial to understanding assembly processes and conservation issues underlying land-use change, is the extent to which functional and phylogenetic diversity may recover in spontaneous recent woodlands. Here, we compared understorey plant communities of recent woodlands (which result from afforestation on agricultural lands during the 20th century) with those of ancient forests (uninterrupted for several centuries) in a hotspot of farmland abandonment in western Europe. We combined taxonomic, functional, and phylogenetic diversity metrics to detect potential differences in community composition, structure (richness, divergence), conservation importance (functional originality and specialization, evolutionary distinctiveness) and resilience (functional redundancy, response diversity). The recent and ancient forests harbored clearly distinct compositions, especially regarding the taxonomic and phylogenetic facets. Recent woodlands had higher taxonomic, functional and phylogenetic richness and a higher evolutionary distinctiveness, whereas functional divergence and phylogenetic divergence were higher in ancient forests. On another hand, we did not find any significant differences in functional specialization, originality, redundancy, or response diversity between recent and ancient forests. Our study constitutes one of the first empirical pieces of evidence that recent woodlands may spontaneously regain plant communities phylogenetically rich and functionally resilient, at least as much as those of ancient relict forests. As passive rewilding is the cheapest restoration method, we suggest that it should be a very useful tool to restore and conserve native forest biodiversity and functions, especially when forest areas are restricted and fragmented.

We aimed to identify the impact of permanent swing mooring on the fast-growing seagrass Zostera marina in a mega-tidal area. Coupling the hydrodynamic MARS3D model to simulate mooring chain movements and in situ measurements of plant traits, we analyzed the structural responses of the eelgrass bed to scraping disturbance in the western English Channel (France). A comparison of the results with a reference site without any permanent swing boat mooring showed a significant impact on eelgrass structure (shoot density, leaf size, leaf dry weight), depending on the direction and distance from the mooring. Zostera marina was absent close to the mooring fixation point in three out of the four directions we evaluated. Beyond 5 m, the canopy height remained lower than in the reference site, most likely due to regular disturbances by mooring chains. Conversely, shoot density beyond 5 m was higher than in the reference site. This adaptive response counter-balanced the decrease in canopy height at these distances. The fluctuations of the structure of the eelgrass cover (number of shoots, leaf length) at a small spatial scale was clearly in accordance with the scraping intensity simulated by the MARS3D model. The tidal currents coupled to tidal amplitude variability imply a small-scale heterogeneous effect of permanent mooring on the benthic compartment, previously undetected by an aerial survey. The present results highlight the interest of coupling approaches so as to understand how physical pressure influences fast-growing species traits. The resulting important modifications could imply a more functional impact such as biodiversity loss and carbon sequestration, which is beyond the scope of the present paper. %B Estuarine, Coastal and Shelf Science %V 235 %P 106581 %G eng %U http://www.sciencedirect.com/science/article/pii/S027277141930068X %R https://doi.org/10.1016/j.ecss.2020.106581 %0 Journal Article %J Bulletin of the Ecological Society of America %D 2019 %T Examples of Understory Plant Communities Observed in Post‐Agricultural Recent Woodlands and Uninterrupted Ancient Forests %A Morel, Loïs %A Barbe, Lou %A Jung, Vincent %A Clément, Bernard %A Schnitzler, Annik %A Frédéric Ysnel %B Bulletin of the Ecological Society of America %V 101 %P e01634 %8 01/2020 %G eng %N 1 %0 Journal Article %J Animal Behaviour %D 2019 %T The first winter influences lifetime wintering decisions in a partially migrant bird %A Chambon, Rémi %A Gélinaud, Guillaume %A Paillisson, Jean-Marc %A Lemesle, Jean-Christophe %A Frédéric Ysnel %A Dugravot, Sébastien %B Animal Behaviour %V 149 %P 23 - 32 %8 Jan-03-2019 %G eng %U https://linkinghub.elsevier.com/retrieve/pii/S0003347219300016 %!

In this study, we seek to provide an evaluation procedure by (1) investigating the distribution of rarity among subtidal rock bottom phyla; (2) searching for potential surrogate phyla with a cross-taxon congruence approach based on their rarity; (3) proposing an appropriate multi-phyla indicator to evaluate the importance of subtidal rocky habitats for conservation. We analysed the distribution of 548 species belonging to 8 phyla sampled in 137 assemblages in subtidal rocky areas located around Brittany, Western France. We applied the Index of Relative Rarity, a flexible method which fits rarity weights to species depending on their respective phyla. We found only weak congruence in rarity patterns among phyla, which prevented any attempt to identify surrogate phyla. This finding has important implications for the conservation of subtidal rocky habitats as it means that there is no shortcut to monitor their rarity: working on a subset of phyla would imply a biased evaluation of biodiversity. Consequently, we propose a multi-phyla Index of Relative Rarity combining all phyla which allowed us to successfully describe rarity patterns across all sampled sites. %B Ecological Indicators %V 77 %P 239–249 %G eng %U http://dx.doi.org/10.1016/j.ecolind.2017.02.012 %R 10.1016/j.ecolind.2017.02.012 %0 Conference Proceedings %B Actes du colloque de Bailleul 2017 « Valeurs et usages des zones humides » %D 2017 %T Le Mont-Saint-Michel et sa baie peuvent-ils se réconcilier ? %A Canard, Alain %A Prigent, Lionel %A Frédéric Ysnel %A Robin, Thierry %A Alexandre Carpentier %A Lefeuvre, Jean-Claude %A Bioret, Frédéric %B Actes du colloque de Bailleul 2017 « Valeurs et usages des zones humides » %7 Documents Phytosociologiques %V 12, série 3 %P 103-112 %8 2019 %G eng %0 Journal Article %J Diversity and Distributions %D 2014 %T Forecasted climate and land use changes, and protected areas: the contrasting case of spiders %A Leroy, Boris %A Bellard, Céline %A Dubos, Nicolas %A Colliot, Arthur %A Vasseur, Manon %A Courtial, Cyril %A Bakkenes, Michel %A Canard, A %A Frédéric Ysnel %K Arthropods %K ensemble forecast %K global changes %K species distribution models %K threatened species %K uncertainty %B Diversity and Distributions %V 20 %P 686-697 %G eng %N 6 %R 10.1111/ddi.12191 %0 Journal Article %J Zookeys %D 2014 %T Validation of Eustiromastix guianae (Caporiacco, 1954) (Araneae, Salticidae) with a first description of the female, and additions to the salticid fauna of French Guiana. %A Courtial, Cyril %A Picard, Lionel %A Frédéric Ysnel %A Pétillon, Julien %X
