Butterflies The mere presence of butterflies adds a heavenly vibe to any garden, but these graceful insects also help beautify plants by pollinating them. One of the best ways to attract a few of these magnificent creatures is by planting liatris, spiky flowers that some butterflies find very appealing. Praying Mantises Praying mantises are like…

How trees could save the climate
Around 0.9 billion hectares of land worldwide would be suitable for reforestation, which could ultimately capture two thirds of human-made carbon emissions. The Crowther Lab of ETH Zurich has published a study in the journal Science that shows this would be the most effective method to combat climate change. The Crowther Lab at ETH Zurich investigates nature-based…

Scientists discover how plants breathe — and how humans shaped their ‘lungs’
Scientists have discovered how plants create networks of air channels -- the lungs of the leaf -- to transport carbon dioxide (CO2) to their cells. Botanists have known since the 19th century that leaves have pores -- called stomata -- and contain an intricate internal network of air channels. But until now it wasn't understood…

How This Popular Garden Plant May Spread Parasites That Harm Monarchs
For monarch butterflies in the eastern United States, life revolves around milkweed, a group of about 100 plants in the genus Asclepius that provide food, shelter and nectar for the iconic insects. During their annual migration to the their overwintering sites in the mountains of Mexico, millions of the butterflies float from milkweed to milkweed…

Mowing for monarchs
You might think that mowing fields wouldn't benefit monarch butterfly populations. New research from Michigan State University, however, shows that disturbances like mowing -- at key times -- might help boost the iconic butterfly's numbers. The results are published in the current issue of Biological Conservation, and they show that strategic grassland management benefits monarchs in…

Free-floating DNA to reveal the health of river and lake ecosystems
The mix of DNA floating in rivers and lakes will finally be used to monitor the state of aquatic ecosystems, after years of tests to show that the technique works. Conventionally, aquatic life is monitored by capturing organisms, either by using nets or scraping under boulders, for examination. These techniques are time-consuming, can harm species and require skilled ecologists. Monitoring fish typically involves using…

Monarch butterfly populations are on the rise
The latest survey of monarch butterfly habitat in Mexico is a testament to the power of conservation. The area of forest occupied by hibernating monarch butterflies in Mexico has increased by 144% in relation to last year’s survey—the biggest growth in the past 12 years. A new colony of monarchs was also found in the…

Mexico’s Monarch Butterflies Are in Grave Danger. Scientists Are Moving an Entire Forest to Save Them.
Tree by tree, Mexican scientists are planting the first stages of a new forest in the mountains of the country’s central Michoacan state. They’re taking saplings from oyamel fir trees further down the mountain and creating a new home for them higher up. Three and a half years ago, the first batch of transplanted trees…

Study on Weed Killers and Monarch Butterflies Spurs Ecological Flap
Monarch butterfly populations have been declining since the 1990s, and several studies have linked this to the proliferation of crops genetically engineered to tolerate the glyphosate-based herbicide Roundup. Crops are routinely doused with it, killing all but the engineered plants—and the casualties include milkweed, on which monarchs exclusively lay their eggs. Some 850 million milkweed…

Where have all the butterflies gone? Monarch butterflies all but vanish in Idaho and the West
Something catastrophically wrong happened in 2018 to monarch butterflies. Idaho wildlife biologist Ross Winton spent years working with monarch butterflies. With the help of volunteers, he would carefully put a tiny tag the size of a paper hole punch on about 30 to 50 of the iconic insects each summer in the Magic Valley. Then…
