Data from: Tree leaf and root traits mediate soil faunal contribution to litter decomposition across an elevational gradient

Saori Fujii, Johannes H. C. Cornelissen, Matty P. Berg & Akira S. Mori
1.Plant litter decomposition is key to carbon and nutrient cycling in terrestrial ecosystems. Soil fauna are important litter decomposers, but how their contribution to decomposition changes with alterations in plant composition and climate is not well established. 2.Here we quantified how soil mesofauna affect decomposition rate interactively with climate and leaf and root traits. We conducted an in situ decomposition experiment using eight dominant tree species per forest site across four elevations (50, 400, 600...

Data from: Intraspecific variation in cephalopod conchs changes during ontogeny: perspectives from three-dimensional morphometry of Nautilus pompilius

Amane Tajika, Naoki Morimoto, Ryoji Wani & Christian Klug
Intraspecific variation of organisms is of great importance to correctly carry out taxonomic work, which is a prerequisite for important disciplines in paleontology such as community paleoecology, biostratigraphy, and biogeography. However, intraspecific variation is rarely studied in ectocochleate cephalopods (ammonoids and nautiloids), in which an excessive number of taxa were established during the past centuries. Since intraspecific variation of fossilized organisms suffers from various biases (time averaging and taphonomy), an extant example is needed for...

Data from: Ontogenetic trajectories of septal spacing in Early Jurassic belemnites from Germany and France, and their palaeobiological implications

Ryoji Wani, Amane Tajika, Kenji Ikuno & Tetsuro Iwasaki
Based on well-preserved belemnites, the ontogenetic trajectories of septal spacing between succeeding chambers were analysed. In the examined species (Passaloteuthis laevigata, Parapassaloteuthis zieteni and Pseudohasitites longiformis) that come from Buttenheim, Germany, and Lixhausen, France, the ontogenetic trajectories of septal spacing follow exponentially increasing trends with no decreasing phase of septal crowding during the earliest ontogenetic stage. The absence of a decreasing trend at the earliest ontogenetic stage is a unique character in contrast with those...

Data from: Biodiversity-ecosystem function relationships change through primary succession

Akira Mori, Takashi Osono, J. Hans C. Cornelissen, Joseph Craine & Masaki Uchida
Ecologists traditionally use environmental parameters to predict successional shifts in compositional characteristics of local species assemblages (environmental control). Another important focus in ecology is to understand functional roles of species assemblages in determining local environmental properties (diversity control). Then, the question emerges: which is the cause, and which is the consequence? To clarify the causal relationships between species assemblages and environmental properties, we focused on seral changes in species/functional diversity of vascular plants in tundra...
