How Social Media is Filling Critical Gaps in Biodiversity Monitoring
A new study demonstrates the significant potential of social media data to improve the tracking of species range shifts driven by climate change. Researchers used the rapid range expansion of the tawny coster butterfly (*Acraea terpsicore*) as a case study, comparing occurrence records from the Global Biodiversity Information Facility (GBIF) with data scraped from Flickr and Facebook. The integration of social media data increased occurrence records by 35%, particularly in megadiverse countries with historically poor GBIF coverage. Species distribution models calibrated with the combined dataset revealed greater expansion rates and captured ecological niches in regions with lower temperatures and higher elevations that were missed by GBIF-only data. This work highlights a novel method to address spatial biases in biodiversity monitoring and track rapid ecological redistribution.
Why it might matter to you: For professionals focused on conservation biology and ecological modeling, this research offers a practical, low-cost tool to enhance data-poor monitoring programs. It directly addresses the challenge of tracking invasive species and climate-induced range shifts in real-time, which is critical for proactive wildlife management and policy. Incorporating such alternative data streams could improve the accuracy of predictive models used for ecosystem services assessment and restoration ecology planning.
