Data from: Effects of artificial light at night on the leaf functional traits of freshwater plants

Leaf traits measured on three species of submerged aquatic plants (Myriophyllum verticillatum L., Potamogeton coloratus Hornem., and Vallisneria spiralis L.) grown under light pollution at night or in the dark. Details about the protocols and the data collection can be found in the article published in Freshwater Biology.

Microbial 16S rRNA gene (DNA) and transcripts (cDNA) along a boreal soil-freshwater-estuary continuum

This repository stores the processed files of the 16S rRNA sequencing reads (DNA and cDNA) of the La Romaine project, which were processed through the DADA2 pipeline. Files are '.rds' files and/or '.csv' files readable by the open statistical software R. The project is part of the Industrial Research Chair in Carbon Biogeochemistry in Boreal Aquatic systems (CarBBAS Chair) led by Paul A. del Giorgio. Samples were pooled by plate ID and season to be processed by DADA2. The number before each '*_seqtab.rds' file corresponds to a pool. ID details are in "splitdf_new.rds". Raw sequences can be found on SRA under the Bioproject number: PRJNA693020. Intermediate processing files are stored here. And scripts are available on <a href="https://github.com/CarBBAS/Paper_Stadler-delGiorgio_ISMEJ_2021">Github</a>. Files are being uploaded as manuscripts are published. Currently available files: <ul> <li>2015-2017: 16S rRNA gene and transcripts (DNA and cDNA) in spring, summer, autumn (shallow sequencing) <ul> <li>Part of the manuscript: "Terrestrial connectivity, upstream aquatic history and seasonality shape bacterial community assembly within a large boreal aquatic network".

Fig. 2 in Molecular phylogeny reveals a new genus of freshwater mussels from the Mekong River Basin (Bivalvia: Unionidae)

Fig. 2. Time-calibrated tree of the subfamily Gonideinae based on the concatenated alignment dataset of COI + 16S + 28S genes. Nodes present time estimates since the most recent common ancestor (tMRCA) in millions of years ago (Mya). Node bars indicate 95% highest posterior density interval (HPD) of the node ages. Sufficiently supported nodes (BPP> 0.95) are marked with '*'. The geologic time scale is according to the Geological Society of America, 2019.

Fig. 1. Maximum likelihood (ML) tree of the subfamily Gonideinae based on the concatenated dataset of COI + 16S + 28S genes. Bootstrap values from ML and posterior probabilities from Bayesian inference analysis (BI) of the major nodes are listed as ML/BI. Nodes with posterior probabilities of BI ≥ 0.95 and ML bootstrap support values ≥ 70 were considered as sufficiently supported nodes (Huelsenbeck & Hillis 1993; Larget & Simon 1999), and are marked with black circles (supported by both BI and ML), white circles (supported only by BI), or grey circles (supported only by ML).

A deep learning dataset for underwater object detection of tropical freshwater fish species in northern Australia

This dataset includes 44,112 images with 82,904 bounding box annotations for 23 tropical freshwater fish taxa from northern Australia.  Images were derived from Remote Underwater Video (RUV) deployments in deep channel and shallow lowland billabongs, Kakadu National Park, Northern Territory Australia. RUV deployments were conducted during the <a href="https://www.dcceew.gov.au/science-research/supervising-scientist">Supervising Scientists</a> annual fish monitoring program in the 2016, 2017 and 2018 recessional flow period (dry season).
