Feathered friends can become unlikely helpers for tropical coral reefs facing climate change threat      (via sciencedaily.com)     Original source 

Tropical coral reefs are among our most spectacular ecosystems, yet a rapidly warming planet threatens the future survival of many reefs. However, there may be hope for some tropical reefs in the form of feathered friends. A new study has found that the presence of seabirds on islands adjacent to tropical coral reefs can boost coral growth rates on those reefs by more than double.

Jays jump in while crows hold out for the treat      (via sciencedaily.com)     Original source 

New research has found that two similar species of birds behave very differently around their favorite food when they have company. Biologists compared the behavior of two species of corvids, Eurasian jays and New Caledonian crows, both capable of displaying self-control through delayed gratification. The researchers found that jays will settle for an immediate, less preferred food option when another bird is present, while crows will always hold out for their favorite food, regardless of the social context.

Climate change shown to cause methane to be released from the deep ocean      (via sciencedaily.com)     Original source 

New research has shown that fire-ice -- frozen methane which is trapped as a solid under our oceans -- is vulnerable to melting due to climate change and could be released into the sea.

Limitations of asteroid crater lakes as climate archives      (via sciencedaily.com)     Original source 

In southern Germany just north of the Danube, there lies a large circular depression between the hilly surroundings: the Nördlinger Ries. Almost 15 million years ago, an asteroid struck this spot. Today, the impact crater is one of the most useful analogues for asteroid craters on early Mars. Studying the deposits of the former lake that formed in the crater is particularly informative. These deposits have been of great interest ever since NASA began exploring Martian craters for signs of water and life on Mars.

New study identifies the greatest threat to wildlife across North America and Canada: people      (via sciencedaily.com)     Original source 

A biology student studied more than 600,000 wildlife rehabilitation center records to look at the human impact on wild animals, from lead poisonings to window strikes to vehicle collisions.

Artificial light is luring birds to cities and sometimes to their deaths      (via sciencedaily.com)     Original source 

Scientists used weather radar data to map bird stopover density in the United States and found that artificial light is a top indicator of where birds will land. City lights lure birds into what can be an ecological trap -- with buildings that lead to collisions, less habitat, scarcer food, and more people and cats. The study provides the first continent-wide maps of migration stopover hotspots in the contiguous United States, and knowing these broadscale layover patterns can help in the development of conservation plans.

More than a meteorite: New clues about the demise of dinosaurs      (via sciencedaily.com)     Original source 

What wiped out the dinosaurs? A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, challenging the traditional narrative that a meteorite alone delivered the final blow to the ancient giants.

Earliest-known fossil mosquito suggests males were bloodsuckers too      (via sciencedaily.com)     Original source 

Researchers have found the earliest-known fossil mosquito in Lower Cretaceous amber from Lebanon. What's more, the well-preserved insects are two males of the same species with piercing mouthparts, suggesting they likely sucked blood. That's noteworthy because, among modern-day mosquitoes, only females are hematophagous, meaning that they use piercing mouthparts to feed on the blood of people and other animals.

Crocodile family tree mapped: New light shed on croc evolution      (via sciencedaily.com)     Original source 

Around 250 million years ago, 700 species of reptiles closely related to the modern-day crocodile roamed the earth, now new research reveals how a complex interplay between climate change, species competition and habitat can help explain why just 23 species of crocodile survive today.

Scientists navigate uncharted waters in fish immunology research      (via sciencedaily.com)     Original source 

Upon infection or immunization, all jawed vertebrate species generate proteins called antibodies that bind and neutralize pathogens. Strong and long-lasting antibody responses in warm-blooded species such as mammals are produced in secondary lymphoid microstructures (SLMs) among which germinal centers (GCs) are the centerpiece. Despite the apparent absence of GCs or similar SLMs in cold-blooded vertebrates (e.g., fish), these species can mount significant antibody responses that can persist for several months. Thus, for decades, the outstanding question has remained as to how and where antibody responses are generated in species that lack GCs or analogous SLM structures.

Aging societies more vulnerable to collapse      (via sciencedaily.com)     Original source 

Societies and political structures, like the humans they serve, appear to become more fragile as they age, according to an analysis of hundreds of pre-modern societies. A new study, which holds implications for the modern world, provides the first quantitative support for the theory that the resilience of political states decreases over time.

Antarctica's ancient ice sheets foreshadow dynamic changes in Earth's future      (via sciencedaily.com)     Original source 

Identifying how and why Antarctica's major ice sheets behaved the way they did in the early Miocene could help inform understanding of the sheets' behavior under a warming climate. Together, the ice sheets lock a volume of water equivalent to more than 50 meters of sea level rise and influence ocean currents that affect marine food webs and regional climates. Their fate has profound consequences for life nearly everywhere on Earth.

Decoding past climates through dripstones      (via sciencedaily.com)     Original source 

A recent study demonstrates how dripstones can be crucial for reconstructing past climates. The new approach can provide a detailed picture of the climate around early human occupations in South Africa.
