Good news for coral reef restoration efforts: Study finds 'full recovery' of reef growth within four years      (via sciencedaily.com)     Original source 

While the majority of the world's reefs are now under threat or even damaged potentially beyond repair, a new study offers some encouraging news: efforts to restore coral reefs not only increase coral cover, but they can also bring back important ecosystem functions, and surprisingly fast.

Reptile roadkill reveals new threat to endangered lizard species      (via sciencedaily.com)     Original source 

The chance sighting of a dead snake beside a sandy track in remote Western Australia, and the investigation of its stomach contents, has led researchers to record the first known instance of a spotted mulga snake consuming a pygmy spiny-tailed skink, raising concerns for a similar-looking, endangered lizard species.

New technique may help scientists stave off coral reef collapse      (via sciencedaily.com)     Original source 

Producing coral skeleton components in the easy-to-use soft-bodied sea anemone Nematostella creates a perfect lab system for studying, and eventually helping, corals threatened by a changing climate.

Loss of nature costs more than previously estimated      (via sciencedaily.com)     Original source 

Researchers propose that governments apply a new method for calculating the benefits that arise from conserving biodiversity and nature for future generations.

Eight new deep-sea species of marine sponges discovered      (via sciencedaily.com)     Original source 

Despite marine sponges being widespread on our planet, their biodiversity and distribution is still poorly known. Even though the Mediterranean Sea is the most explored sea on Earth, a study reveals the presence of new sponge species and new records in unexplored habitats such as underwater caves or mountains around the Balearic Islands.

Early life adversity leaves long-term signatures in baboon DNA      (via sciencedaily.com)     Original source 

Early experiences in an animal's life can have a significant impact on its capacity to thrive, even years or decades later, and DNA methylation may help record their effects. In a study of 256 wild baboons, researchers found that resource limitation during early life was associated with many differences in DNA methylation, a small chemical mark on the DNA sequence that can affect gene activity.

Global warming is affecting bats' hibernation      (via sciencedaily.com)     Original source 

Global change is altering the physiology of the hibernation and behavior of bats, according to a study carried out over a twenty year period. Given the milder winters we are having, bats are accumulating less fat reserves in autumn, they shorten their hibernation periods and they leave their winter shelter sooner. These changes could alter the migration pattern of bats and the phenology of their seasonal displacements.

Herbivores, displaced by ocean warming, threaten subtropical seagrass meadows      (via sciencedaily.com)     Original source 

The findings suggest that subtropical seagrasses are less resilient to heavy grazing from marine herbivores, in part because they receive less sunlight relative to their tropical counterparts. As tropical herbivores move into subtropical waters, overgrazing may prevent subtropical seagrass meadows from persisting in these environments.

After decades of Arctic sea ice getting faster and more hazardous for transport, models suggest a dramatic reversal is coming      (via sciencedaily.com)     Original source 

Will ice floating in the Arctic Ocean move faster or slower over the coming decades? The answer to this question will tell us whether marine transportation can be expected to get more or less hazardous. It might also have important implications for the rate of ice cover loss, which is hugely consequential for Northern Indigenous communities, ecosystems, and the global climate system. While observational data suggest the trend has been towards faster sea ice speeds, climate models project that those speeds will slow down during the summer season. This contrast has led to some questions around the plausibility of the model projections.

We know the Arctic is warming -- What will changing river flows do to its environment?      (via sciencedaily.com)     Original source 

Scientists recently combined satellite data, field observations and sophisticated numerical modeling to paint a picture of how 22.45 million square kilometers of the Arctic will change over the next 80 years. As expected, the overall region will be warmer and wetter, but the details -- up to 25% more runoff, 30% more subsurface runoff and a progressively drier southern Arctic, provides one of the clearest views yet of how the landscape will respond to climate change.

8 in 10 lizards could be at risk due to deforestation      (via sciencedaily.com)     Original source 

These reptiles move around tree trunks to seek warmth or shade. With trees disappearing, they would have trouble controlling their body temperature, a new study shows.

Less ice in the Arctic Ocean has complex effects on marine ecosystems and ocean productivity      (via sciencedaily.com)     Original source 

Most of the sunlight reaching the Arctic Ocean is reflected to space by sea ice, effectively shielding ocean ecosystems from sunlight. As the Arctic sea ice continues its downward trend, larger areas of the ocean become exposed to sunlight for longer periods, potentially allowing more primary production on the seafloor. However, according to a new study, this anticipated increase in primary production does not seem to be occurring uniformly across the Arctic Ocean.
