Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
RivFishTIME: A global database of fish time‐series to study global change ecology in riverine systemsNARA Subscribed
Motivation We compiled a global database of long‐term riverine fish surveys from 46 regional and national monitoring programmes and from individual academic research efforts, with which numerous basic and applied questions in ecology and global change research can be explored. Such spatially and temporally extensive datasets have been lacking for freshwater systems in comparison to terrestrial ones. Main types of variables con...
In copepods, morphologically‐indistinguishable but genetically‐different cryptic species complexes are frequently found, such as the Acanthodiaptomus pacificus complex that is commonly found in Japanese lakes and ponds. In the present study, the fauna of Japanese freshwater calanoid copepods were extensively reexamined using molecular techniques, and the autecology of each calanoid species was deduced based on the molecular id...
Animals can be important in modulating ecosystem‐level nutrient cycling, although their importance varies greatly among species and ecosystems. Nutrient cycling rates of individual animals represent valuable data for testing the predictions of important frameworks such as the Metabolic Theory of Ecology ( MTE ) and ecological stoichiometry ( ES ). They also represent an important set of functional traits that may reflect both...
