“…This survey mainly focused on lakes and streams, including a few ponds and rivers. Lakes in the TP are often characterized by relatively high salinity and the absence of hydrophyte, which limits the occurrence of diverse chironomids (Bouchard Jr et al, 2022 ; Zhang et al, 2007 ). Comparatively, fresh streams could provide more diverse habitats due to their great divergences in altitude along with gradients in environmental variables, such as glacial influence, groundwater recharge, substrate, water temperature, and oxygen saturation (Hamerlik & Jacobsen, 2012 ).…”

The main aim of this study was to curate a COI barcode library of Chironomidae from the Tibetan Plateau (TP) as an essential supplement to the public database. Another aim is to evaluate the current status of the public database of Chironomidae in aspects of taxonomic coverage, geographic representation, barcode quality, and efficiency for molecular identification, the Tibetan Plateau, China. In this study, 512 individuals of Chironomidae from the TP were identified based on morphological taxonomy and barcode analysis. The metadata of public records of Chironomidae were downloaded from the BOLD, and the quality of the public barcodes was ranked using the BAGS program. The reliability of the public library for molecular identification was evaluated with the newly curated library using the BLAST method. The newly curated library comprised 159 barcode species of 54 genera, of which 58.4% of species were likely new to science. There were great gaps in the taxonomic coverage and geographic representation in the public database, and only 29.18% of barcodes were identified at the species level. The quality of the public database was of concern, with only 20% of species being determined as concordant between BINs and morphological species. The accuracy of molecular identification using the public database was poor, and about 50% of matched barcodes could be correctly identified at the species level at the identity threshold of 97%. Based on these data, some recommendations are included here for improving barcoding studies on Chironomidae. The species richness of Chironomidae from the TP is much higher than ever recorded. Barcodes from more taxonomic groups and geographic regions are urgently needed to fill the great gap in the current public database of Chironomidae. Users should take caution when public databases are adopted as reference libraries for the taxonomic assignment.

“…Encompassing a diversity of lake ecosystems, from alpine freshwater to lowland salt lakes, this region increasingly faces environmental threats from excessive grazing and climate change (Bouchard, Hayford and Ferrington 2022). The statistical analysis reveals a positive relationship between SDG 6.6.1 sub-indicators on lakes and rivers permanent and seasonal water area and (a) SDG 1.4.1 on proportion of population using basic drinking water services, (b) urban population as percentage of total population.…”

Measuring Progress: Water-related Ecosystems and the SDGs

2023

The 2030 Agenda for Sustainable Development and its Sustainable Development Goal (SDG) framework were constructed to interlink economic, environmental and social dimensions. The importance of achieving sustainability relies on understanding the synergies and trade-offs between implemented actions and the actions that may hinder or empower them. The Measuring Progress series explores the relationship between environmental indicators and economic or social indicators. This third edition of the Measuring Progress report focuses on statistical methods to understand these interlinkages through the prism of water ecosystems and the SDGs. In so doing, it provides insight into how freshwater- and marine-related ecosystems are impacted by various drivers, pressures, and actions, through use of statistical analysis.
