Four Freshwater Snail Species Occurences from Peking University's Weiming Lake Published on Global Biodiversity Information Facility (GBIF)

In early September 2023, the China Biodiversity Conservation and Green Development Foundation (CBCGDF) published 4 species of freshwater snails on Global Biodiversity Information Facility (GBIF) , based on the report by 2 young students who collected samples from the Peking University's Weiming Lake and reported to the CBCGDF's GBIF WG. These species include Bellamya purificata, Bellamya angularia, Semisulcospira cancellata, and Bellamya lapillorum.

Freshwater snails, as essential members of ecosystems, play crucial roles in benthic community structures. As benthic organisms, they not only help maintain water cleanliness by feeding on algae and organic debris but also occupy a significant position in the food chain, serving as a primary food source for predatory species like fish. The abundance and distribution of freshwater snails directly impact the diversity of benthic organisms, contributing to the stability of freshwater ecosystem structures and functions.

According to the data collectors, Shouyong and Shouyuan, there were no signs of an invasive alien species, the Golden Apple Snail, in Peking University's wetlands. The children originally wanted to investigate the distribution of the Golden applesnails (an invasive species) in northern China. They visited multiple wetlands in Beijing to observe and to collect samples. From the limited samples collected at five collection points along the lake's edge in Peking University, instead, they found over 20 freshwater snails, including at least four different species.

We appreciate the efforts of these young citizen scientists in exploring and observing nature. We believe that children can also contribute to biodiversity informatics. Everybody can make a difference for mainsteaming biodiversity, according to Biodiversity Conservation in Our Neighborhood (BCON)'s philosophy.

We would like to express our gratitude to scientists at the East China Normal University's Aquatic Ecology Restoration Research Group for their valuable guidance regarding species identification.

Biodiversity data from the Global Biodiversity Information Facility (GBIF) hold significant importance in advancing sustainable development goals. GBIF, by aggregating biodiversity data from around the world, provides robust support for scientific research, policy-making, and sustainable development. GBIF data not only helps the world better understand the distribution of biodiversity on Earth and its changing trends but also serve as a scientific basis for conservation decisions in various fields, including ecosystem conservation, protection of endangered species, and the promotion of sustainable agriculture and fisheries. They facilitate the harmonious development of humanity and nature.
