Climate-stressed trees get a boost from new microbial partnerships
Plants live across wide ranges of heat and cold and rain and drought, but they don’t fill their niches alone. Along with the animals and insects that live on and around a tree — pitching in now and then to aid pollination or pest control or seed dispersal — there are innumerable microbes in the soil (like various fungi that grow alongside tree roots). These microbes can blunt the normal stresses of life by helping trees draw in more nutrients and water or influencing the time they leaf out or flower to best match seasonal conditions.
Polar fish are less likely to die early, so they prioritize growth over reproduction
Polar fish experience lower mortality than tropical fish, allowing them to delay reproduction until later in life when they are larger and can produce more eggs, according to a study by Mariana Álvarez-Noriega at Monash University in Australia and colleagues, publishing May 25th in the open access journal PLOS Biology.

Broad Climate Change Concern in Florida Linked With Recent Extreme Weather
An increasing number of Floridians agree that human actions are causing climate change, including a record number of Florida Republicans. Virtually all respondents (90 percent) believe climate change is happening, with 65 percent attributing the causes to human actions, including 49 percent of GOP voters. Belief in and concern about human-caused climate change appears to be translating into support for policies to reduce emissions and reduce impacts. The explanation for this emerging consensus may be grounded in people’s lived experiences with weather events.

Marine Seagrass Meadows Show Resilience to ‘Bounce Back’ After Die-Offs
A study in Florida Bay, one of the largest global contiguous seagrass systems, examined if a phytotoxin that accumulates as seagrass ecosystems become more enriched in nutrients prevents a marine seagrass, turtlegrass, from recruiting into open bare sediment following die-off events. While they do “bounce back,” long-term monitoring indicates the timeframe for recovery after major die-off events is at least a decade. Turtlegrass can successfully recruit into open bare sediment following die-off events due to biomass partitioning.
Conformer-Dependent Reactivity of Carbonyl Oxides Leads to Dramatically Different Atmospheric Fates
The air pollutant secondary organic aerosol (SOA) forms when ammonia and amines react with oxygenated species. When ammonia is present when alkenes react with ozone, SOA increases in size and numbers. This may be due to Criegee intermediates. New research found that a particular amine, dimethylamine, reacts 34,000 times faster with one version of the Criegee intermediate acetaldehyde oxide than with another version of the same compound.

Increasing temperature or nutrients in an ecosystem can destabilize food webs, but when temperature and nutrients increase together it can be difficult to predict the combined effects. This study examined a laboratory microbial food web consisting of bacterial prey and protist predators. It found that temperature and nutrients can alter the dynamics of microbial communities by changing how species’ abundances and average body sizes relate to each other.
