Understanding the role of soil microbial communities in oak woodland restoration using DNA metabarcoding (Links to an external site)

Soil microbial communities play a crucial role in oak woodland restoration, influencing the success of conservative herbaceous species reintroductions. Using DNA metabarcoding, researchers at Missouri Botanical Garden’s Shaw Nature Reserve studied how different restoration ages affect soil microbial composition and plant growth. Their findings suggest that younger restorations may offer more beneficial microbial conditions for conservative plant species, potentially improving nutrient uptake and stress resistance.

MoBot uses AI to learn how trees move. And to save millions of plant specimens. (Links to an external site)

The Missouri Botanical Garden is leveraging AI to digitize its nearly 8 million plant specimens, creating an online database to support conservation efforts and preserve critical ecological data. By combining AI with historical and genetic information, the Garden is also advancing research on tree migration and ecosystem adaptation to climate change, while ensuring these technologies complement rather than replace human expertise.

Matthew Austin, an ecologist and biodiversity postdoctoral fellow with the Living Earth Collaborative at Washington University in St. Louis, published a study in the American Journal of Botany that describes changes to the flowering time and other important life cycle events in Leavenworthia species, a group of small flowering plants found in glades in Missouri.

Shifting Climate Zones Pose a Major Threat to Terrestrial Ecosystems (Links to an external site)

New research published in Regional Environmental Change, funded in part by a Living Earth Collaborative seed grant, reveals that climate zone shifts in Kenya between 1980 and 2020 are leading to hotter and drier conditions, threatening ecological diversity and food security. The study found that tropical climate zones expanded, while arid regions grew by over 50,000 square kilometers. This shift, driven by rising temperatures and altered precipitation patterns, significantly impacts agriculture, particularly in regions dependent on rain-fed farming. The findings highlight the urgent need for adaptation strategies to mitigate the effects of climate change on ecosystems and livelihoods in Kenya and similar regions.

TGI-led research finds shifting climate regions leading to hotter, drier conditions across Kenya (Links to an external site)

Research published in Regional Environmental Change has shown that as climate zones shift toward hotter and drier conditions, ecological diversity will decline, posing a major threat to terrestrial ecosystems with far-reaching social and ecological impacts, This work was supported in part by the Taylor Geospatial Institute and a seed research grant from the Living Earth Collaborative at Washington University in St. Louis.

Bunkered ex situ plant conservation and páramo biodiversity farms (Links to an external site)

The “páramo biodiversity farms” initiative in Colombia’s Sumapaz region represents an innovative approach to biodiversity conservation, emphasizing the creation of ex situ living collections of threatened plants like Espeletia. These collections serve as tools for research, education, and ecological restoration while fostering collaboration with local communities. By prioritizing sustainable, community-driven conservation efforts, the initiative challenges traditional “ark paradigm” approaches and promotes biodiversity management rooted in the ecosystems and populations most affected.

No, autumn leaves are not changing color later because of climate change (Links to an external site)

A red maple is fully red. The sun is shining through the leaves.

Many people believe that climate change is pushing back the start of fall leaf color to later in the year. The general thinking is that the warmer conditions anticipated under climate change will mean that trees can “hang on” to their green, energy-producing leaves longer. But scientists do not actually see this happening across North American forests, according to LEC Biodiversity Fellow, Susanne S. Renner, an expert at Washington University in St. Louis.

Watermelon cut into triangles

The oldest known seeds from a watermelon relative, dating back 6,000 years to the Neolithic period, were found during an archaeological dig in Libya. An investigation of these seeds led by LEC Biodiversity Fellow, biologist Susanne S. Renner at Washington University in St. Louis, reveals some surprises about how our ancestors used a predecessor of today’s watermelon.

With funding support from LEC, researchers look at whether Ozark oases at Tyson Research Center — climate change refugia — could help species persist in spite of rising temperatures.

St. Louis, MO – Sustainable Cities (Links to an external site)

Looking at the STL Arch from Illinois

Low-income communities and communities of color are disproportionately harmed by air pollution from burning fossil fuels and by the health risks of climate change. Transitioning away from fossil fuels takes economic and political support, a difficult ask for St. Louis, a city located in a state with one of the highest rates of coal consumption in the country. New technical and scientific funding support from foundations, combined with a recent push by city leaders, religious communities, and clean energy advocates, is putting in place sustainability programs and policies that are moving the Midwest city in a new direction.

A seedy slice of history: Watermelons actually came from northeast Africa (Links to an external site)

A new study published in the Proceedings of the National Academy of Sciences rewrites the origins of domesticated watermelons. The study corrects a 90-year-old mistake that lumped watermelons into the same category as the South African citron melon. Instead, researchers, including Susanne S. Renner, a first author now at Washington University in St. Louis, found that a Sudanese form with non-bitter whitish pulp, known as the Kordofan melon (C. lanatus), is the closest relative of domesticated watermelons.

Andean forests have high potential to store carbon under climate change. The study — which draws upon two decades of data from 119 forest-monitoring plots in Colombia, Ecuador, Peru, Bolivia and Argentina — was produced by an international team of scientists including researchers supported by the Living Earth Collaborative at Washington University in St. Louis. The lead author was Alvaro Duque from the Universidad Nacional de Colombia Sede Medellín.

New research from an international team including Rachel Penczykowski, an assistant professor of biology at Washington University in St. Louis shows that infection actually makes a plant more susceptible to secondary infection — in experiments and in the wild. The findings are published Aug. 31 in Nature Ecology & Evolution.

The Congo Basin is home to the world’s second-largest rainforest and a unique array of biodiversity. But the ecosystem’s remote location cannot protect it from the threat of poaching. Special correspondent Monica Villamizar and videographer Phil Caller traveled to the Central African Republic before the pandemic to report on indigenous tribal hunters working to protect endangered wildlife.

Mankind is the problem, and we appear to be hastily destroying life around us, says a Washington University in St. Louis biodiversity expert about new research with a WashU connection. (Links to an external site)

A new study co-authored by LEC Biodiversity Fellow and president emeritus of Missouri Botanical Garden, Peter Raven, appears in the Proceedings of the National Academy of Sciences. The research highlights the alarming rate of vertebrate species extinction, attributing it primarily to human activities.
