Even Sonoran Desert plants aren't immune to climate change      (via sciencedaily.com) 

In North America's hottest, driest desert, climate change is causing the decline of plants once thought nearly immortal and replacing them with shorter shrubs that can take advantage of sporadic rainfall and warmer temperatures.

Habitat will dictate whether ground beetles win or lose against climate change      (via sciencedaily.com) 

The success of North American crops from corn to Christmas trees partly depends on a relatively invisible component of the food web -- ground beetles. Nearly 2,000 species of ground beetle live in North America. New research shows that some of these insects could thrive while others could decline as the climate changes. The team found that the response will largely depend on the species' traits and habitats and could have significant implications for conservation efforts.

The global economics of climate action      (via sciencedaily.com) 

Climate change has serious consequences for the environment and people and is a major threat to economic stability. A new assessment reviews innovative, integrated research that underpins the economic case for strong near-term climate action.

Genome of a drought-tolerant plant: Many genes are involved in 'resurrection'      (via sciencedaily.com) 

Some plants can survive months without water, only to turn green again after a brief downpour. A recent study shows that this is not due to a 'miracle gene.' Rather, this ability is a consequence of a whole network of genes, almost all of which are also present in more vulnerable varieties.

Drought, heat waves worsen West Coast air pollution inequality      (via sciencedaily.com) 

A new study found drought and heat waves could make air pollution worse for communities that already have a high pollution burden in California, and deepen pollution inequalities along racial and ethnic lines. The study also found financial penalties for power plants can significantly reduce people's pollution exposure, except during severe heat waves.

Phytoplankton blooms offer insight into impacts of climate change      (via sciencedaily.com) 

The first study into the biological response of the upper ocean in the wake of South Pacific cyclones could help predict the impact of warming ocean temperatures, researchers believe.

Going beyond English is critical for conservation      (via sciencedaily.com) 

Research in languages other than English is critically important for biodiversity conservation and is shockingly under-utilized internationally, according to an international research team.

Coffee plantations limit birds' diets      (via sciencedaily.com) 

A new study explores a record of birds' diets preserved in their feathers and radio tracking of their movements to find that birds eat far fewer invertebrates in coffee plantations than in forests, suggesting that the disturbance of their ecosystem significantly impacts the birds' dietary options.

How fishermen benefit from reversing evolution of cod      (via sciencedaily.com) 

Intense fishing and over-exploitation have led to evolutionary changes in fish stocks like cod, reducing both their productivity and value on the market. These changes can be reversed by more sustainable and far-sighted fisheries management. A new study shows that reversal of evolutionary change would only slightly reduce the profit of fishing, but would help regain and conserve natural genetic diversity.

Bigger flowers, greater rewards: Plants adapt to climate disruptions to lure pollinators      (via sciencedaily.com) 

There's been a well-documented shift toward earlier springtime flowering in many plants as the world warms. The trend alarms biologists because it has the potential to disrupt carefully choreographed interactions between plants and the creatures -- butterflies, bees, birds, bats and others -- that pollinate them.

East Coast, US, landslide impacts from Puerto Rico to Vermont and in between      (via sciencedaily.com) 

In the U.S., we may often think of landslides as primarily a West Coast problem, mostly plaguing the mountainous terrain of California, Oregon, and Washington. New research highlights the major impacts of landslides on the U.S. East Coast and what is being done to save lives and deal with the damages.

High winds can worsen pathogen spread at outdoor chicken farms      (via sciencedaily.com) 

A study of chicken farms in the West found that high winds increased the prevalence of Campylobacter in outdoor flocks, a bacterial pathogen in poultry that is the largest single cause of foodborne illness in the U.S. Researchers found that about 26% of individual chickens had the pathogen at the 'open environment' farms in the study, which included organic and free-range chicken farms. High winds the week prior to sampling and the farms' location in more intensive agricultural settings were linked to a greater prevalence of Campylobacter.

A mechanistic and probabilistic method for predicting wildfires      (via sciencedaily.com) 

In the event of dry weather and high winds, power system-ignited incidents are more likely to develop into wildfires. The risk is greater if vegetation is nearby. A new study provides the methodology for predicting at what point during a high wind storm, powerline ignition is likely.

Entire populations of Antarctic seabirds fail to breed due to extreme, climate-change-related snowstorms      (via sciencedaily.com) 

The arrival of the new year is a prime time for Antarctic birds like the south polar skua, Antarctic petrel, and snow petrel to build nests and lay their eggs. However, from December 2021 to January 2022, researchers did not find a single skua nest on Svarthamaren, one of the regions where the birds go to raise their young. Similarly, the number of Antarctic petrel and snow petrel nests dropped to almost zero.

The world's atmospheric rivers now have an intensity ranking like hurricanes      (via sciencedaily.com) 

Atmospheric rivers, which are long, narrow bands of water vapor, are becoming more intense and frequent with climate change. A new study demonstrates that a recently developed scale for atmospheric river intensity (akin to the hurricane scale) can be used to rank atmospheric rivers and identify hotspots of the most intense atmospheric rivers not only along the U.S. West Coast but also worldwide.
