“…Taking into account that birds and butterflies, which both have notably high dispersal capacities, are already experiencing climatic debts of 212 and 135 km, respectively (Devictor et al., 2012), we may have serious doubts about the ability of Collembola to keep up with climate change through their active dispersal. Like other organisms such as plants that are unlikely to migrate fast enough to track the rapidly changing climate, adaptation must play an increasingly important role (Jump & Penuelas, 2005; Ponge, 2020). There are hopeful examples of soil fauna showing rapid evolutionary changes in response to climate change (Bataillon et al., 2016).…”

“…Dispersal estimates for collembolan species are scarce but lie in the range of few (~5) centimetres per week during the favourable season. Thus, springtail assemblages, at a community level, are expected to select habitats by active movement within a diameters of up to 200 meters (Chauvat et al., 2014; Ojala & Huhta, 2001; Ponge & Salmon, 2013; Ponge, 2020; Treasure & Chown, 2013). Taking into account that birds and butterflies, which both have notably high dispersal capacities, are already experiencing climatic debts of 212 and 135 km, respectively (Devictor et al., 2012), we may have serious doubts about the ability of Collembola to keep up with climate change through their active dispersal.…”

“…There is a solid consensus around the fact that the responses of species to withstand climate change can be grouped around two major strategies: to disperse or to adapt (Berg et al, 2010;Jump & Penuelas, 2005). Springtails, and most likely all soil fauna, are no exception and when experiencing increasingly adverse environmental conditions may either 'move or change' (Ponge, 2020). To move Even though the only example with a springtail species reported some degree of ontogenetic plasticity (i.e.…”

1. The capacity to forecast the effects of climate change on biodiversity largely relies on identifying traits capturing mechanistic relationships with the environment through standardized field experiments distributed across relevant spatial scales. The effects of short-term experimental manipulations on local communities may overlap with regional climate gradients that have been operating during longer time periods. However, to the best of our knowledge, there are no studies simultaneously assessing such long-term macroecological drivers with local climate manipulations.2. We analysed this issue with springtails (Class Collembola), one of the dominant soil fauna groups, in a standardized climate manipulation experiment conducted across six European countries encompassing broad climate gradients. We combined community data (near 20K specimens classified into 102 species) with 22 eco-morphological traits and reconstructed their phylogenetic relationships to track the evolution of adaptations to live at different soil depths, which is key to cope with desiccation. We then applied joint species distribution models to investigate the combined effect of the regional aridity gradient with the local experimental treatment (drought and warming) over the assembly of springtail communities and tested for significant trait-environment relationships mediating their community-level responses.

“…Species that typically inhabit the lower litter layers and soil include the majority of Poduromorpha, including Hypogastruridae and Onychiuridae that were clearly separated from those lacking a molar plate. However, the phylogenetic clustering of springtail soil vertical stratification levels was less well‐defined, and may reflect the ability of species to occupy and move between stratifications levels, and the flexibility of hemiedaphic members to shift levels in response to limited resource availability and extreme conditions (Ponge, 2020).…”

Phylogenies of traits and functions in soil invertebrate assemblages

et al. 2022

Soil invertebrates are members of terrestrial ecosystems, contributing to the processing of organic matter, resulting in carbon and nutrient cycling that is essential for continuous productivity. By linking species delineations, morphological traits and measured or inferred functional roles, we demonstrate a method for functional identification of soil faunal assemblages based on molecular information. Here we align the genetic interrelatedness and functional trait expression in nematodes and springtails. Nematodes were assigned feeding guild, plant parasitic feeding type and coloniser-persister (c-p) value, with springtail sequences assigned to soil vertical stratification level, soil moisture preference and a selection of morphological traits. We found that both nematode and springtail feeding preferences show significant phylogenetic clustering. In contrast, greater dispersal was found amongst nematode coloniser-persister (c-p) values and springtail soil vertical stratification level and moisture preferences. Minimum patristic (p) distances between species supported the clustering amongst nematode feeding guilds, with plant feeders being separated from all other guilds by at least p = 0.99. Distances between endoparasitic, ectoparasitic and sedentary plant parasitic nematodes were also distinct with minimal distances of p = 0.35-0.72 between parasitic types. Springtail stratification level and soil moisture preferences showed greater dispersion across phylogenies, with negligible between-group minimum patristic distances. However, nematode c-p values and springtail moisture preference alignments indicate some genetic conservation at the genus level. These results indicate how ecosystems can direct trait conservation beyond that of environmental stimuli. Being able to assign functional traits to novel sequences will allow individual species' likely contribution to ecosystem functioning to be inferred without the need for exact taxonomic identification. More broadly, such information can advance our understanding of the evolution of soil faunal traits and the contribution of diverse soil assemblages to functional soil systems, particularly those with a high proportion of undescribed species.

“…It is now of wide acceptance that diffuse co-evolution (Fox, 1988) and eco-evolutionary feedbacks (Post & Palkovacs, 2009;Ponge, 2020) contributed to explain evolution in a species interaction context, at both micro-and macroevolutionary levels (terHorst et al, 2018). However, that natural selection might occur at community level is still largely speculative, even if well-known from a theoretical point of view (Johnson & Boerlijst, 2002;Traulsen & Nowak, 2006).…”

Communities are shaped by the activity of ecosystem engineers, which modify their environment to their benefit and that of subordinate species within their functional domain. Communities are defined as embedded assemblages of interactions, from cells to landscapes. They are threatened by present-day global changes which trigger the invasive nature of ecological engineers, with cascading effects. This perspective paper starts with a definition of ecosystem engineers and functional domains in the frame of developments in community ecology. Then I show that the concepts of ecosystem engineer and functional domain explain (i) most of the observed cases of community boundaries, and (ii) the passage from small-scale interactions among individuals to community-wide processes of dynamics and stability. I will further show that ecological engineering exists at various scales, from viruses to landscapes, functional domains being embedded in a flexible manner. At last, I will show that threats posed by global changes to communities are mainly mediated by their negative or positive effects on ecosystem engineers.
