Using global satellite data, a research team has mapped the tree cover of the world’s protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiversity overall.
Maintaining species-rich and resilient ecosystems is key to preserving biodiversity and mitigating climate change. Here, megafauna – the part of the animal population in an area that is made up of the largest animals – plays an important role. In a new study published in the scientific journal One Earth, an international research team, of which Lund University is a part, has investigated the intricate interplay between the number of voracious herbivores and the diversity of trees in the world’s protected areas.
“Our findings reveal a fascinating and complex story of how large herbivorous animals shape the world’s natural landscapes. The tree cover in these areas is sparser, but the diversity of the tree cover is much higher than in areas without large herbivores,” says Lanhui Wang, a researcher in physical geography and ecosystem science at Lund University.
“In our global analysis, we find a substantial association between the biomass of large herbivores and varied tree cover in protected areas, notably for browsers and mixed-feeders such as elephants, bison and moose and in non-extreme climates”, explains the study’s senior author, Jens-Christian Svenning, professor at Aarhus University.
Hereby, the study supports that large wild herbivores promote a diverse vegetation structure, creating a rich habitat for many other species. This is due to the animals’ consumption of vegetation as well as physical disturbances.
According to Lanhui Wang, these new research findings highlight the need to integrate large herbivores into restoration and conservation strategies. Not only for the sake of the animals themselves but also for the vital role they play in shaping landscapes and influencing biodiversity. The researchers argue that this aspect is not sufficiently considered within the framework of sustainable land management and ecosystem restoration.
“At a time when global initiatives are intensely focused on combating climate change and biodiversity loss, our findings highlight the need for a broader and more nuanced discussion about ecosystem management and conservation measures. It is of utmost importance to integrate understanding of the ecological impact of megafauna into this,” says Lanhui Wang.
The UN has declared the 2020s as the decade of ecosystem restoration. In total, 115 countries have agreed to restore up to 100,000 square kilometres of nature in total. To achieve this, more wild-living large herbivores are needed worldwide, says Lanhui Wang.
“I believe that we will need to protect and conserve large herbivores to achieve the UN goals. Megafauna are crucial for tree cover, which in turn promotes carbon sequestration and a diversity of habitats,” says Lanhui Wang.

As climate scientist Don Falk was hiking through a forest, the old, green pines stretched overhead. But he had the feeling that something was missing. Then his eyes found it: a seedling, brittle and brown, overlooked because of its lifelessness. Once Falk's eyes found one, the others quickly fell into his awareness. An entire generation of young trees had died.

Researchers at DZNE and Charité - Universitätsmedizin Berlin have pioneered a novel treatment for the most common autoimmune encephalitis. By reprogramming white blood cells to target and eliminate disease-causing cells, the approach offers a new level of precision and efficiency. The technique has proven successful in laboratory studies, clinical trials in humans are already being planned.
NMDA receptor encephalitis is the most common form of antibody-caused brain disease, in which antibodies suddenly attack the brain, thus turning against the patient’s own body. “In ...
In order to survive, organisms must control the pressure inside them, from the single-cell level to tissues and organs. Measuring these pressures in living cells and tissues in physiological conditions is a challenge.
In research that has its origin at UC Santa Barbara, scientists now at the Cluster of Excellence Physics of Life (PoL) at the Technical University in Dresden (TU Dresden), Germany, report in the journal Nature Communications a new technique to ‘visualize’ these pressures as organisms develop. These measurements can help understand how cells and tissues ...
Texas is a huge state. And with that size comes soil diversity, supply chain delays, climate differences, material and labor costs and many other things to consider when evaluating the budget for a highway project.
To account for all of these variables, a University of Texas at Arlington researcher is building a price estimation and visualization tool for the Texas Department of Transportation (TxDOT) through a $200,000 U.S. Department of Transportation grant. Mohsen Shandashti, associate professor in the Department of Civil Engineering, is leading a team to develop that tool, which ...

MINNEAPOLIS/ST. PAUL (11/03/2023) — Focal segmental glomerulosclerosis (FSGS) is a rare kidney disorder that affects children and adults, and can lead to kidney failure. New findings from a team led by the University of Minnesota Medical School show patients with FSGS who were treated with the medication sparsentan experienced improved kidney function—making it a potential new treatment option for the disorder.
The research, published today in the New England Journal of Medicine, suggests sparsentan may provide kidney protection by significantly reducing excess protein in urine — known as proteinuria, a proven indicator of kidney damage.
“FSGS ...
