Study uncovers major hidden human-driven bird extinctions      (via sciencedaily.com)     Original source 

Humans have wiped out around 1,400 bird species -- twice as many as previously thought -- with major implications for the ongoing biodiversity crisis, a new study has found. The estimated extinctions would mean almost 12 per cent of bird species have died out over modern human history, since the Late Pleistocene around 130,000 years ago, with the vast majority of them becoming extinct directly or indirectly due to human activity.

Researchers invent 'methane cleaner': Could become a permanent fixture in cattle and pig barns      (via sciencedaily.com)     Original source 

In a spectacular new study, researchers have used light and chlorine to eradicate low-concentration methane from air. The result gets us closer to being able to remove greenhouse gases from livestock housing, biogas production plants and wastewater treatment plants to benefit the climate.

15 most pressing issues for conservation, including invertebrate decline and changing marine ecosystems      (via sciencedaily.com)     Original source 

Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.

Move over Blitzen: Geese outpace reindeer impacts on Arctic ecosystems      (via sciencedaily.com)     Original source 

A research team is studying how expanding populations of two local herbivores -- reindeer and geese -- on Svalbard will impact the future of the ecosystem on the islands.

Trees in wetter regions more sensitive to drought      (via sciencedaily.com)     Original source 

This holiday season brings surprising news about your Christmas tree. Scientists just discovered that globally, trees growing in wetter regions are more sensitive to drought. That means if your tree hails from a more humid clime, it's likely been spoiled for generations.

Wildfires also impact aquatic ecosystems      (via sciencedaily.com)     Original source 

Researchers have shown that the effects of wildfires are not limited to terrestrial ecosystems. Aquatic ecosystems are also undergoing rapid changes. The study found that fire debris transforms lakes and other aquatic ecosystems, with implications for fisheries and water quality.

How forests smell -- a risk for the climate?      (via sciencedaily.com)     Original source 

Plants emit odors for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers carried out a study to investigate how biodiversity influences the emission of these substances. For the first time, they were able to show that species-rich forests emit less of these gases into the atmosphere than monocultures. It was previously assumed that species-rich forests release more emissions. The Leipzig team has now been able to disprove this assumption experimentally.

The solar forest      (via sciencedaily.com)     Original source 

What would be the most effective use of a certain plot of land in terms of the climate crisis: planting a forest, which is a natural means of absorbing carbon dioxide from the atmosphere, or erecting fields of solar panels, which reduce the emission of carbon dioxide into the atmosphere? This dilemma has long been debated by decision-makers around the world. Now, for the first time -- based on findings from arid areas and on comprehensive measurements of the energy flow exchanged between the ground and the atmosphere -- we may have an answer to this question.

Study overturns conventional wisdom about wild turkey nesting survival      (via sciencedaily.com)     Original source 

A new study finds that precipitation levels during nesting season are not related to reproductive success for wild turkeys, which runs counter to the conventional wisdom regarding the role that rainfall plays in wild turkey nesting success. The findings shed new light on how climate change may affect wild turkey populations.

Nature and animal emojis don't accurately represent natural biodiversity      (via sciencedaily.com)     Original source 

The current emoji library doesn't accurately represent the 'tree of life' and the breadth of biodiversity seen in nature according to a new analysis. A team of conservation biologists categorized emojis related to nature and animals and mapped them onto the phylogenetic tree of life. They found that animals are well represented by the current emoji catalog, whereas plants, fungi, and microorganisms are poorly represented. Within the animal kingdom, vertebrates were over-represented while arthropods were underrepresented with respect to their actual biodiversity.

Adapting to hypoxia: Zooplankton influence the efficiency of the biological carbon pump in the Humboldt Current off Peru      (via sciencedaily.com)     Original source 

Marine organisms play a crucial role in the global carbon cycle. Phytoplankton absorb carbon dioxide from the atmosphere and sequester it in organic matter that sinks to the deep ocean where it can be stored for long periods of time. Until now, this process -- the biological carbon pump -- was thought to be particularly efficient in oxygen-poor areas. A new study suggests that the influence of certain zooplankton species on the biological carbon pump has been underestimated.

New insights into Zebra mussel attachment fibers offer potential solutions to combat invasive species, develop sustainable materials      (via sciencedaily.com)     Original source 

A recent study has revealed that an unlikely event, occurring over 12 million years ago played an important role in shaping one of Canada's most damaging invasive species. Zebra and quagga mussels, belonging to the Dreissenid family, are widespread freshwater invasive species throughout North America that present a significant danger to native ecosystems by competing for resources. Using a fibrous anchor called a byssus, Dreissenid mussels contribute to biofouling on surfaces and obstruct intake structures in power stations and water treatment plants.

Study reshapes understanding of mass extinction in Late Devonian era      (via sciencedaily.com)     Original source 

A recently published study puts forth a new theory that volcanic eruptions combined with widespread ocean detoxification pushed Earth's biology to a tipping point in the Late Devonian era, triggering a mass extinction.
