The study published in <i>Nature</i> tries to resolve a debated topic: Are insect populations declining? Several studies have reported a decline in insect populations and diversity while others have questioned this.

The 2021 theme, “We’re part of the solution”, was chosen to be a continuation of the momentum generated last year under the over-arching theme, “Our solutions are in nature”, which served as a reminder that biodiversity remains the answer to several sustainable development challenges.</p> Mon, 17 May 2021 18:22:25 +0000 frederique.mazerolle@mcgill.ca 265915 at /newsroom /newsroom/andrew-gonzalez Wed, 23 Dec 2020 20:51:46 +0000 shirley.cardenas@mcgill.ca 254373 at /newsroom /newsroom/channels/news/new-canadian-headquarters-global-biodiversity-research-network-323136 <p>The Group on Earth Observations - Biodiversity Observation Network (GEO BON), a global research network and community of practice dedicated to improved monitoring of Earth’s biodiversity, announces the relocation of its headquarters from Leipzig, Germany, to Montreal, Canada.</p> <p>GEO BON responds to the urgent need for the best possible data and knowledge to support decisions to avoid unsustainable biodiversity loss.
