La polinización se desplomó 31% en campos contaminados

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 12 April 202212 April 2022

Los niveles de contaminación del aire por debajo de los límites “seguros” (y más bajos que los que comúnmente se encuentran en las ciudades) llevaron a una disminución significativa de la polinización de hasta por 10 insectos comunes.

A yellow-and-black bee perches on the petals of a small yellow mustard flower. The bee faces left and was imaged at a range close enough that the flecks of pollen that cover the bee are visible.

Pollination Plummeted 31% in Polluted Fields

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 18 February 202212 April 2022

Air pollution levels below “safe” limits (and lower than those commonly found in cities) led to a significant decrease in pollination by 10 common insects.

Evolution is More Important than Environment for Water Uptake

by Valeriy Ivanov 8 February 20223 May 2022

Despite conventional assumptions, a new study shows that evolutionary proximity of species defines root water uptake strategies, not their position in landscape or ambient environment.

Invasive Plants and Climate Change Will Alter Desert Landscapes

Katherine Kornei, Science Writer by Katherine Kornei 13 January 202213 January 2022

In experiments conducted in Biosphere 2, invasive buffelgrass weathers higher temperatures and drought conditions better than its native brethren.

The Flowers that Bloom in the Spring (but Later)

by David S. Schimel 31 December 20217 February 2023

Mismatch between the pace of climate change and crop phenology may signal a new challenge for climate change adaptation.

Plant Root Exudates Mediate Soil Nutrient Transport

by D. Scott Mackay 9 December 20218 April 2022

Plant roots mediate solute transport through the soil immediately surrounding them by introducing polymers and other binding compounds that disrupt water transport pathways between soil pore spaces.

Thirsty Plants Pull Water from Bedrock

Katherine Kornei, Science Writer by Katherine Kornei 18 October 202129 March 2023

Shrubs and trees across the United States routinely sip water stored in bedrock, a discovery that has implications for the terrestrial water cycle.

Famine Weed Becomes More Toxic, Invasive in Carbon-Rich Atmosphere

by Fionna M. D. Samuels 22 September 202129 March 2023

A noxious weed’s success in Australia could indicate that some plants are benefitting from our carbon-rich atmosphere, becoming more invasive, competitive, and toxic.

Permanence of Nature-Based Climate Solutions at Risk

Eric Davidson, president-elect of AGU by E. Davidson 22 July 20213 May 2022

Conserving native ecosystems helps sequester carbon and mitigate climate change, but new statistical modeling questions the permanence of California’s carbon-rich forests with climate change.

A Well-Balanced Ecosystem Uses Water Most Efficiently

Elizabeth Thompson by Elizabeth Thompson 13 May 20216 March 2023

Excess of a single nutrient, such as nitrogen, may boost plant productivity, but the imbalance leads to less efficient water use as plants scramble for the nutrients they lack.
