Scientists surveying the birdlife of Borneo have discovered a startling surprise: an undescribed species of bird, which has been named the spectacled flowerpecker. While scientists and birdwatchers have previously glimpsed the small, gray bird in lowland forests around the island, the Smithsonian team is the first to capture and study it, resulting in its formal scientific description as a new species.

Read moreResearchers have reported that a bird species' ability to adapt to seasonal temperature changes may be one factor in whether it can better withstand environmental disruption. The researchers studied 135 bird species in the Himalayas and found that species living in the seasonal western Himalayas adapted to the conversion of forests to agricultural land better than birds native to the tropical eastern Himalayas. Results such as these could help conservationists better determine where to focus their efforts.
Read moreNative to South America, imported fire ants have now spread to parts of North America and elsewhere around the world. These invasive pests have painful stings that, in some cases, can cause serious medical problems, such as hypersensitivity reactions, infections and even kidney failure. Now, researchers have identified pyridine alkaloids that, along with other venom components, could contribute to these conditions.

Read moreIn 2018, vast amounts of snow were spread across most of the Arctic region and did not melt fully until late summer, if at all. Researchers documented the consequences of this extreme weather event at Zackenberg, Northeast Greenland by extensively monitoring all components of the local ecosystem for more than 20 years, allowing them to compare life in the extreme year of 2018 to other, more 'normal,' years.
Read moreSome corals can recover after massive mortality episodes caused by the water temperature rise. This survival mechanism in the marine environment — known as rejuvenation — had only been described in some fossil corals so far. A new study reveals the first scientific evidence of the rejuvenation phenomenon in vivo in Cladocora caespitosa coral colonies, in the marine reserve in Columbrets, in the coast of Castellón.
Read moreThe intensity of summer algal blooms has increased over the past three decades, according to a first-ever global survey of dozens of large, freshwater lakes. Researchers used 30 years of data from the Landsat 5 near-Earth satellite and created a partnership with Google Earth Engine to reveal long-term trends in summer algal blooms in 71 large lakes in 33 countries on six continents.
Read moreResearch on energy production from biomass usually focuses on the amount of energy generated. But it is also important to consider how much energy goes into the process, a component that is often neglected. A study from the University of Illinois takes a look at the bioconversion efficiency of two products often used as biomass for energy production, miscanthus giganteus and sugarcane bagasse.
Read moreThe researchers set out to understand where nature contributes the most to people and how many people may be affected by future changes. By 2050, up to 5 billion people could be at higher risk of water pollution, coastal storms and under-pollinated crops.
