Ice age cycles had minimal impact on the genetic diversity of European trees, finds a new study. High diversity arose from traits like long lifespans and pollen traveling vast distances. This resilience offers hope for forests adapting to today’s rapid climate changes.
Phytoplankton blooms in Antarctic waters help slow ice shelf melting by 7%. These marine microbes trap heat near the surface and provide shade, cooling deeper waters and reducing the impact of sunlight. However, a feedback loop with iron from melting ice limits their growth, highlighting a complex climate interaction.
Researchers have uncovered genetic traits in wild tomatoes, specifically *Solanum pimpinellifolium*, that enhance salt stress tolerance. By analyzing plant vigor, shoot mass, and transpiration rates, they identified new genes linked to resilience in salty soils. These findings could inform breeding strategies to create more salt-tolerant crops, boosting agricultural sustainability.
The first continent-wide mapping study of plant life across Antarctica reveals growth in previously uncharted areas and is set to inform conservation measures across the region.
Scientists have developed drought and salt-resistant tomato plants by discovering a new stress-response mechanism. By engineering these plants to produce a synthetic molecule that activates this mechanism, they enhance the plants’ resilience. This breakthrough could ensure stable tomato production despite adverse climate conditions, supporting global food security.
Researchers discovered forests with cold-air pooling, where colder air settles in valleys, reversing typical temperature patterns. These areas could protect cold-adapted species from climate change, serving as refuges and aiding conservation efforts. The study emphasizes the importance of such forests for species adaptation and carbon storage.
Scientists have uncovered how the enzyme carboxysomal carbonic anhydrase (CsoSCA) works in cyanobacteria. This discovery could lead to engineering crops that capture carbon dioxide more efficiently, boosting yields and resilience to climate change.
A study reveals that while most people trust climate scientists, a skeptical minority can impede climate action. Researchers stress that even minority distrust can have significant political consequences, emphasizing the need for scientists to maintain credibility and transparency to bolster public trust and drive climate action.
Climate change is the top threat to pollinators like bees and butterflies, crucial for biodiversity and food security, according to a new review paper. The study highlights how climate-induced habitat changes and human activities harm pollinators, urging integrated conservation strategies to mitigate these impacts and safeguard our food systems.
Climate change has advanced flowering in Doñana National Park by 22 days, as researchers discovered. Over 35 years, rising temperatures shifted peak flowering from May 9th to April 17th. This alters plant interactions, impacting pollinators and ecosystem dynamics, highlighting climate’s profound effects on biodiversity and the environment.
