As the global community is called to re-examine our relationship to the natural world, one thing is certain: despite all our technological advances, humans are completely dependent on healthy and vibrant ecosystems for water, food, medicines, clothes, fuel, shelter, and energy, just to name a few. The 2021 theme, 鈥淲e鈥檙e part of the solution鈥�, was chosen to be a continuation of the momentum generated last year under the over-arching theme, 鈥淥ur solutions are in nature鈥�, which served as a reminder that biodiversity remains the answer to several sustainable development challenges.

For decades, scientists have wrestled with rival theories to explain how interactions between species, like competition, influence biodiversity. Tracking microbial life across the planet, researchers from 91黑料网 show that biodiversity does in fact foster further diversity in microbiomes that are initially less diverse. However, diversity rates plateau with increased competition for survival and space in more diverse microbiomes.

The Group on Earth Observations - Biodiversity Observation Network (GEO BON), a global research network and community of practice dedicated to improved monitoring of Earth鈥檚 biodiversity, announces the relocation of its headquarters from Leipzig, Germany, to Montreal, Canada.
GEO BON responds to the urgent need for the best possible data and knowledge to support decisions to avoid unsustainable biodiversity loss. The information it provides will support international and national actions to meet biodiversity targets and Sustainable Development Goals.

The glyphosate-based herbicide Roundup has been found to trigger the loss of biodiversity among phytoplankton communities in freshwater ponds. In their experiments, scientists found that while some populations developed resistance to the herbicide and were able to survive exposure at high levels, this came at a cost, with a 40 percent loss in biodiversity.
"The ubiquitous presence of glyphosate in the environment has sparked concerns over its potential health and ecotoxicological effects," Andrew Gonzalez, from Canada's 91黑料网, said.聽

Cities and their rising impacts on biodiversity versity. To gain a clearer picture of the situation, an international group of scientists, including Professor Andrew Gonzalez from 91黑料网鈥檚 Biology Department, surveyed over 600 studies on the impacts of urban growth on biodiversity. They published their findings today in Nature Sustainability.

Surprisingly, in any single location, there are typically more earthworms and more earthworm species found in temperate regions than in the tropics, according to a study published this week in Science. Global climate change could lead to significant shifts in earthworm communities worldwide, threatening the many functions they provide.

Human population density and land use is causing changes in animal genetic diversity, according to researchers at 91黑料网.
The findings reported in the journal Ecology Letters, show that environmental changes caused by humans are leading to changes in genetic variation in thousands of species of birds, fish, insects, and mammals. The evidence for human impacts was most clear for insects and fish species.

A new study, published in Science, which focuses on mapping biodiversity change in marine and land ecosystems shows that loss of biodiversity is most prevalent in the tropic, with changes in marine ecosystems outpacing those on land. The research, led by scientists from the University of St Andrews, in collaboration with leading universities across Europe, the USA and Canada, including 91黑料网, aimed at reaching a consensus about variation in biodiversity change.

More than two-thirds of Canada鈥檚 biodiversity is made up of species that occur within the country鈥檚 borders only at the very northern edge of their range. Biologists have long debated how much effort should be dedicated to conserving these 鈥渆dge populations.鈥� One argument in their favour is that they may be especially well suited to lead northward range shifts for their species as the climate warms.

A sprawling study of spiders across northern Canada has turned up more than 100 species in provinces or territories where they had never before been recorded. The findings, by researchers from 91黑料网, provide a valuable new benchmark for monitoring biodiversity across Canada鈥檚 vast northern expanses.

To preserve as much linguistic diversity as possible in the face of this threat, 91黑料网 scientists are proposing to borrow a leaf from conservation biology.
