“…For plot-level analyses (n = 53) and correlations with other plant traits, see Table 4 123 leaf litter calcium, determines organic horizon C stocks and turnover (Hobbie et al 2006;Reich et al 2005). Yet, earthworm abundance was not strongly correlated with mineral soil C in this study, perhaps because the dominant earthworm on site (Lumbricus terrestris) is a surface litter feeder with permanent burrows in the mineral soil (Jegou et al 2000) and minimal influence on mineral soil mixing.…”

“…Earthworm activity plays an important role in changing soil properties (Lee, 1985;Pallant and Hilster, 1996;Boyle et al, 1997;Capowiez et al, 2000;Ponder et al, 2000). By making burrows, earthworms greatly influence soil structure and therefore modify soil transport characteristics (Jégou et al, 2000). By ingesting organic debris, they enhance soil nutrients (for example C, N and P) availability beneficial to the plant growth.…”

The effect of earthworm (Eisenia fetida) activity on soil pH, dissolved organic carbon (DOC), fraction distribution pattern and bioavailability of rare earth elements (REEs) Y, La, Ce, Pr and Nd in nine Chinese soils were investigated using pot experiments. A three-step extraction procedure recommended by the European Community (Standards, Measurements and Testing Programme) was used to fractionate REEs in soils into water soluble, exchangeable and carbonate bound (B1), Fe-and Mn-oxides bound (B2) and organic matter and sulfide bound (B3). Inoculated with earthworms, the soil pH, DOC and water-soluble rare earth elements fraction increased. A significant correlation was obtained between the increased DOC and the increased water-soluble REEs. REEs in fraction B1 increased after earthworm inoculation, while those in fraction B3 decreased. No significant differences were observed for REEs in fraction B2. The biomass and the concentrations of REEs in wheat shoots and roots increased after the treatment with earthworms. The results demonstrated that earthworm activity increased the mobility and bioavailability of REEs in soils.

“…From the scarce examples of ecological studies, the most studied animals have been arthropods and annelids, and in a lesser extend other kingdoms such as plants and fungi (Figure 3). It is particularly evident that one of the most popular topics so far is soil ecology (Davey et al., 2011; Harrison, Gardner, Tollner, & Kinard, 1993; Tollner, 1991), and specifically the study of worm burrows (Amossé, Turberg, Kohler‐Milleret, Gobat, & Le Bayon, 2015; Auclerc, Capowiez, Guérold, & Nahmani, 2013; Capowiez, Monestiez, & Belzunces, 2001; Capowiez, Pierret, & Moran, 2003; Francis, Tabley, Butler, & Fraser, 2001; Jégou, Capowiez, & Cluzeau, 2001; Jégou, Cluzeau, Hallaire, Balesdent, & Tréhen, 2000; Jégou, Cluzeau, Wolf, Gandon, & Tréhen, 1998; Jégou, Hallaire, Cluzeau, & Tréhen, 1999; Jégou et al., 2002; Langmaack, Schrader, Rapp‐Bernhardt, & Kotzke, 1999; Pagenkemper et al., 2015; Pelosi, Grandeau, & Capowiez, 2017; Rogasik, Schrader, Onasch, Kiesel, & Gerke, 2014; Schrader, Rogasik, Onasch, & Jegou, 2007), mostly because of the ease of studying this type of sample. Soil can be considered a matrix where the components can be detected through X‐ray CT without any preparation (i.e., staining).…”

Imaging techniques are a cornerstone of contemporary biology. Over the last decades, advances in microscale imaging techniques have allowed fascinating new insights into cell and tissue morphology and internal anatomy of organisms across kingdoms. However, most studies so far provided snapshots of given reference taxa, describing organs and tissues under “idealized” conditions. Surprisingly, there is an almost complete lack of studies investigating how an organism′s internal morphology changes in response to environmental drivers. Consequently, ecology as a scientific discipline has so far almost neglected the possibilities arising from modern microscale imaging techniques. Here, we provide an overview of recent developments of X‐ray computed tomography as an affordable, simple method of high spatial resolution, allowing insights into three‐dimensional anatomy both in vivo and ex vivo. We review ecological studies using this technique to investigate the three‐dimensional internal structure of organisms. In addition, we provide practical comparisons between different preparation techniques for maximum contrast and tissue differentiation. In particular, we consider the novel modality of phase contrast by self‐interference of the X‐ray wave behind an object (i.e., phase contrast by free space propagation). Using the cricket Acheta domesticus (L.) as model organism, we found that the combination of FAE fixative and iodine staining provided the best results across different tissues. The drying technique also affected contrast and prevented artifacts in specific cases. Overall, we found that for the interests of ecological studies, X‐ray computed tomography is useful when the tissue or structure of interest has sufficient contrast that allows for an automatic or semiautomatic segmentation. In particular, we show that reconstruction schemes which exploit phase contrast can yield enhanced image quality. Combined with suitable specimen preparation and automated analysis, X‐ray CT can therefore become a promising quantitative 3D imaging technique to study organisms′ responses to environmental drivers, in both ecology and evolution.
