1. Desiccation stress is lethal to most animals. However, some microinvertebrate groups have evolved coping strategies, such as the ability to undergo anhydrobiosis (i.e. survival despite the loss of almost all body water). Tardigrades are one such group, where the molecular mechanisms of anhydrobiosis have been more thoroughly studied. Despite the ecological, evolutionary and biotechnological importance of anhydrobiosis, little is known about its inter- and intra-specific variability nor its relationship with natural habitat conditions or phylogenetic history.
2. We developed a new index—anhydrobiotic recovery index (ARI)—to evaluate the anhydrobiotic performance of tardigrade populations from the family Macrobiotidae. Moreover, we compared the explanatory role of habitat humidity and phylogenetic history on this trait using a variance partitioning approach.
3. We found that ARI is correlated with both microhabitat humidity and yearly rainfall, but it is mostly driven by phylogenetic niche conservatism (i.e. a high portion of ARI variation is explained by phylogeny alone). Finally, we showed that anhydrobiotic performance is highly variable, even between closely related species, and that their response to local ecological conditions is tightly linked to their phylogenetic history.
4. This study not only presents key insights into an emerging model system, but also provides a new methodological approach for wider scale studies of the ecological and evolutionary implications of anhydrobiosis.

First records of limnoterrestrial tardigrades (Tardigrada) from Haida Gwaii, British Columbia, Canada
Massa, E.; Vecchi, M.; Calhim, S.; Choong, H. (Taylor & Francis, 2023)Moss samples were collected from trees and rocks in Haida Gwaii, British Columbia, Canada, and examined for the presence of tardigrades. Specimens from 24 taxa were found in 17 out of the 22 examined samples. New species ... -
Sisubiotus hakaiensis sp. nov. (Tardigrada, Macrobiotidae), a new tardigrade species from Calvert Island (British Columbia, Canada)
Vecchi, Matteo; Choong, Henry; Calhim, Sara (Museum National D'Histoire Naturelle, 2022)Tardigrades reports from British Columbia (Canada) trace back to 1908 and numerous species have been recorded from this region, despite the relatively few published sampling studies. We describe by integrative taxonomy ... -
Morphology, phylogenetic position, and mating behaviour of a new Mesobiotus (Tardigrada) species from a rock pool in the Socorro Box Canyon (New Mexico, USA)
Vecchi, M.; McDaniel, J. L.; Chartrain, J.; Vuori, T.; Walsh, E. J.; Calhim, S. (Taylor & Francis, 2023)Tardigrades have been recorded from a variety of habitats including mosses, lichens, leaflitter, streams, and marine sediments; however, reports from rock pools are still scarce. Rock pools across the world are known to ... -
Desiccation risk favours prevalence and diversity of tardigrade communities and influences their trophic structure in alpine ephemeral rock pools
Vecchi, Matteo; Ferrari, Claudio; Stec, Daniel; Calhim, Sara (Springer, 2022)Rock pools are ephemeral freshwater habitats characterized by their small size, well-defined boundaries, and periodic desiccation, making them ideal model systems to answer numerous ecological questions. Although there are ... -
Spore production monitoring reveals contrasting seasonal strategies and a trade‐off between spore size and number in wood‐inhabiting fungi
Norros, Veera; Halme, Panu; Norberg, Anna; Ovaskainen, Otso (Wiley-Blackwell, 2023)Traits related to reproduction and dispersal drive the assembly and dynamics of species communities and can explain and predict how species respond to habitat loss and fragmentation and to the changing climate. For fungi, ...
