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...
The bacterioplankton assemblage in Crater Lake, Oregon (U.S.A.), is different from communities found in other oxygenated lakes, as demonstrated by four small subunit ribosomal ribonucleic acid (SSU rRNA) gene clone libraries and oligonucleotide probe hybridization to RNA from lake water. Populations in the euphotic zone of this deep (589 m), oligotrophic caldera lake are dominated by two phylogenetic clusters of currently uncu...
Interaction between Introduced Trout and Larval Salamanders ( Ambystoma macrodactylum ) in High‐Elevation LakesNARA Subscribed
The larval stage of the long‐toed salamander (Ambystoma macrodactylum) is the top vertebrate predator in high‐elevation fishless lakes in the North Cascades National Park Service Complex, Washington (U.S.A.). Although most of these high‐elevation lakes were naturally fishless, trout have been stocked in many of them. We sought to determine the effects of physicochemical factors and introduced trout on abundance and behavior of...
