The Maya built and maintained reservoirs that were in use for more than 1,000 years.

To investigate this issue, a research team conducted a climate change experiment where they exposed boreal and temperate tree species to warming and drought treatments to better understand how fungi and their tree hosts respond to environmental changes. Their findings revealed that the combined effects of warming and water stress will likely result in major disturbances of ectomycorrhizal networks and may harm forest resilience and function.

For a long time, tropical forests have acted as a carbon sink, taking more carbon out of the air than they release into it, a process that has moderated the impact of climate change. But new research found that in 2015 -- 2016, when an El Niño climate event resulted in drought and the hottest temperatures ever recorded, South American forests were unable to function as a carbon sink.

Scientists have assembled the genome sequences of nearly 300 varieties of potatoes and its wild relatives to develop more nutritious, disease-free, and weather-proof crop.

That is the central finding of a long-term study of the influence of climate and climate change on trees in the Black Forest.

Property exposed to such climate risks, especially in California, is project to climb substantially if emission-reduction measures are not taken.

Yet less than 20% of croplands are equipped for irrigation. A new study finds that by the middle of the 21st century under a moderate greenhouse gas emissions scenario, the benefits of expanded irrigation will outweigh the costs of installation and operation over an expanded portion of current U.S. croplands. The study maps where it makes the most sense to install irrigation for corn and soybeans and if there's enough water to do so.

Instead, the environment itself selected for drought-tolerant microbes. And while those hardy microbes were doing their thing, they just happened to make plants more drought-tolerant, too.

But as extreme weather and changing socioeconomic conditions make this so-called 'heroic viticulture' even more challenging, scientists worry these grapes and their cultural histories are at risk.

Through extensive experiments, a team was able to demonstrate that roots have their own temperature sensing and response system. In a new study, the scientists also provide a new explanation for how roots themselves detect and react to higher temperatures. The results could help develop new approaches for plant breeding.

Two recent studies based on the data suggest that drought can lower the survival odds, slow the growth and even skew the ratio of female-to-male painted turtles inhabiting the ponds of the Cornhusker State. Those outcomes emerged despite the water level of a sampled pond in southwestern Nebraska remaining relatively steady throughout the observed periods of drought.

A new study has found that when the leaves of a plant are exposed to dry air (low humidity), they send a shoot-to-root signal, using abscisic acid (ABA), to tell the roots to keep growing. This is a surprising finding as ABA is usually thought to be a growth inhibitor, not a growth promoter.

Based on the analysis, the scientists predict trees in the western and southern Amazon face the greatest risk of dying. They also warn that previous scientific investigations may have underestimated the impact of drought on the rainforest because those studies focused on the central-eastern part of the forest, which is the least vulnerable to drought.

Unfortunately, spawning Chinook salmon are increasingly younger and concentrated within fewer age groups, with the oldest age classes of spawners rarely seen in recent years.

The growth of the European beech has so far suffered decline mainly in southern Europe. European beech is Germany's most important native forest tree species and it is most commonly found in Central Europe. A research team has now been able to show that the European beech is suffering from increasing drought stress in summer in northern Germany as well. This climate stress is particularly pronounced at warmer sites, when there is a higher density of these trees together, and on very sandy soils.

The findings highlight the importance of preserving the world's remaining old-growth forests, which are biodiversity strongholds that store vast amounts of planet-warming carbon, according to forest ecologists.

These results can be used both in agriculture and in forestry for selecting plants with the best chemistry to resist climate challenges.

But the story gets more complex from there. Wheat and barley arrived on the scene at about the same time, but early farmers only used water management techniques for wheat. The results raise awareness that the dispersal of domesticated crops and the knowledge of best using them can be traced independently across time and space.

During the study period, an extremely strong El Niño event occurred, leading to a stronger and longer drought than normal. Seasonally dry tropical forests (SDTFs), which experience an annual dry season, are considered drought-tolerant. Nevertheless, the study found that seedling mortality increased in SDTFs when severe and prolonged drought occurred.

The research also shows that incorporating how plants change soil structures can improve Earth system models. Thu, 27 Oct 2022 12:39:36 EDT //www.koonmotors.com/releases/2022/10/221027123936.htm
