Livestock overgrazing influences both microbial communities and nutrient cycling in terrestrial ecosystems. However, the role of overgrazing in regulating the relationship between soil biodiversity and nitrogen availability remains largely unexplored. We performed long-term grazing exclusion experiments across eight sites along precipitation gradient covering three major types of grassland in northern China to compare the linkage between soil microbial diversity and N availability in overgrazed versus non-grazed conditions. We found a positive association between fungal diversity...

Data from: Multiple late-Pleistocene colonisation events of the Antarctic pearlwort Colobanthus quitensis (Caryophyllaceae) reveal the recent arrival of native Antarctic vascular flora

Aim: Antarctica’s remote and extreme terrestrial environments are inhabited by only two species of native vascular plants. We assessed genetic connectivity amongst Antarctic and South American populations of one of these species, Colobanthus quitensis, to determine its origin and age in Antarctica. Location: Maritime Antarctic, sub-Antarctic islands, South America Taxon: Antarctic pearlwort Colobanthus quitensis (Caryophyllaceae) Methods: Four chloroplast markers and one nuclear marker were sequenced from 270 samples from a latitudinal transect spanning 21–68° S....

Data and code from \"A dimmer shade of pale: revealing the faint signature of local assembly processes on the structure of strongly filtered plant communities\"

Jesús López-Angulo, Marcelino De La Cruz, David S. Pescador, Ana M. Sánchez & Adrián Escudero
Trait-based ecology suggests that abiotic filtering is the main mechanism structuring the regional species pool in different subsets of habitat-specific species. At more local spatial scales, other ecological processes may add on giving rise to complex patterns of functional diversity (FD). Understanding how assembly processes operating on the habitat-specific species pools produce the locally observed plant assemblages is an ongoing challenge. Here, we evaluated the importance of different processes to community assembly in an alpine...

Data from: Crops and their wild progenitors recruit beneficial and detrimental soil biota in opposing ways

Rubén Milla
Aims Conventional agriculture promotes negative feedbacks of soil microbes on crop performance (plant soil feedbacks, PSFs) by stimulating species-specific pathogens. Crop traits, modified by domestication, also influence PSFs. Therefore, we asked if crop cultivars and their wild progenitors promote soil pathogens and mutualists differently, and thus trigger different PSFs. Methods We studied PSFs in cultivated varieties and wild progenitors of ten crops. In a first season, we grew all genotypes separately in a common soil...

Data on epiphytic lichens along elevational gradients in South Tyrol, Italy

Juri Nascimbene, Hugo Saiz, Alessandro Chiarucci & Matteo Dainese
1. Several studies have evaluated lichen responses in terms of shifts in species climate suitability, species richness, and community composition. In contrast, patterns of co-occurrence among species that could be related to complex species interactions have received less consideration. Biotic interactions play a major role in shaping species niches, fitness, and adaptation to new environments. Therefore, considering the specific relationships among co-occurring species is essential to further deepen our knowledge of biodiversity response to climate...

The biogeography of thermal risk for terrestrial ectotherms: scaling of thermal tolerance with body size and latitude

Juan Rubalcaba & Miguel Ángel Olalla-Tárraga
1. Many organisms are shrinking in size in response to global warming. However, we still lack a comprehensive understanding of the mechanisms linking body size and temperature of organisms across their geographical ranges. Here we investigate the biophysical mechanisms determining the scaling of body temperature with size across latitudes in terrestrial ectotherms. 2. Using biophysical models, we simulated operative temperatures experienced by lizard-like ectotherms as a function of microclimatic variables, body mass and latitude and...
