Aim – Although soil biodiversity is extremely rich and spatially variable, both in terms of species and trophic groups, we still know little about its main drivers. Here, we contrast four long-standing hypotheses to explain the spatial variation of soil multi-trophic diversity: energy, physiological tolerance, habitat heterogeneity, and resource heterogeneity. Location – French Alps Methods – We built on a large-scale observatory across the French Alps (Orchamp) made of seventeen elevational gradients (~90 plots) ranging...

Interpreting the mammal deposits of Cloggs Cave (SE Australia), GunaiKurnai Aboriginal Country, through community-led partnership research

Palaeontological animal bone deposits are rarely investigated through research partnerships where the local First Nations communities have a defining hand in both the research questions asked and the research processes. Here we report research undertaken through such a partnership approach at the iconic archaeological site of Cloggs Cave (GunaiKurnai Country, East Gippsland), in the southern foothills of SE Australia’s Great Dividing Range. A new excavation was combined with detailed chronometric dating, high-resolution 3D mapping, and...

Spectra induce polarization data of bacteria in soil

Yalin Song, Xiaoqing Shi, André Revil & Xueyuan Kang
Real-time monitoring of microbial activity in porous media is still facing critical challenges because conventional analytical procedures are intrusive. Induced polarization (IP) has shown promises as a non-intrusive monitoring approach of such process. However, there is still a lack of quantitative analysis of soil column experiments to show how IP-based parameters can be related to the density of bacteria. The evolution of bacteria density and induced polarization is here performed in a soil-packed column experiment...

Searching for genetic evidence of demographic decline in an arctic seabird: beware of overlapping generations

Emeline Charbonnel, Claire Daguin, Lucille Caradec, Eléonore Moittié, Olivier Gilg, Maria Gavrilo, Hallvard Strom, Mark L Mallory, Grant Gilchrist, R. I. Guy Morrisson, Raphael Leblois, Camille Roux, Jonathan M Yearsley, Glenn Yannic & Thomas Broquet
Genetic data are useful for detecting sudden population declines in species that are difficult to study in the field. Yet this indirect approach has its own drawbacks, including population structure, mutation patterns, and generation overlap. The ivory gull (Pagophila eburnea), a long-lived Arctic seabird, is currently suffering from rapid alteration of its primary habitat (i.e., sea ice), and dramatic climatic events affecting reproduction and recruitment. However, ivory gulls live in remote areas, and it is...

Full-factorial breeding experiment with lake char (Lake Geneva, winter 2017/2018)

Laura Garaud, David Nusbaumer, Christian De Guttry, Laurie Ançay, Stéphan Jacquet, Emilien Lasne & Claus Wedekind
We sampled 16 wild lake char (Salvelinus umbla) and used their gametes to investigate the genetic consequences of different mating scenarios. A full-factorial breeding was used to separate additive genetic from maternal environmental effects, and embryos were raised singly after sublethal exposures to a pathogen, a common pollutant, or water only. In all treatment groups, embryo development was strongly reduced with increased genetic relatedness between the parents. Contrary to predictions of ‘good genes’ sexual selection,...

Data collected for: The contrasted impacts of grasshoppers on soil microbial activities in function of ecosystem productivity and herbivore diet

Sébastien Ibanez
Herbivory can have contrasted impacts on soil microbes and nutrient cycling, which has stimulated the development of conceptual frameworks exploring the links between below- and aboveground processes. The “productivity model” predicts that herbivores stimulate microbial activities and accelerate nutrient mineralization in productive ecosystems, while they have an opposite effect in less productive ecosystems. In parallel, the “diet model” predicts that herbivores feeding on conservative plants accelerate nutrient cycling while those feeding on exploitative plants decelerate...
