"It is sometimes said that scientists are unromantic, that their passion to figure out robs the world of beauty and mystery. But is it not stirring to understand how the world actually works — that white light is made of colors, that color is the way we perceive the wavelengths of light, that transparent air reflects light, that in so doing it discriminates among the waves, and that the sky is blue for the same reason that the sunset is red?

Do you ever wonder what happens to the fish in a frozen lake?

Do you ever wonder what happens to the fish in a frozen lake? | Gaia Diary | Scoop.it
Winter-kill events are more common in lakes much smaller than Mendota, says Vander Zanden, where the volume of water makes those events unlikely.

“The fish are there in the fall and they are there again in the spring,” Vander Zanden says. “The whole food web is alive and kicking in the winter.”

The environment determines Caribbean hummingbirds’ vulnerability – University of Copenhagen

The environment determines Caribbean hummingbirds’ vulnerability – University of Copenhagen | Gaia Diary | Scoop.it
Hummingbirds’ specialization and vulnerability are often predicted based on their physical traits. Scientists now found that this is not the case for hummingbirds on the Caribbean islands. Instead, the bird’s environment is the determining factor. The new study was led by scientists from Center for Macroecology, Evolution and Climate, University of Copenhagen, and published today in the scientific journal Proceedings of the Royal Society B.

Deep impact: Deep-sea wildlife more vulnerable to extinction than first thought

Deep impact: Deep-sea wildlife more vulnerable to extinction than first thought | Gaia Diary | Scoop.it
We have only known about the existence of the unusual yeti crabs (Kiwaidae)—a family of crab-like animals whose hairy claws and bodies are reminiscent of the abominable snowman—since 2005, but already their future survival could be at risk.

New Oxford University research suggests that past environmental changes may have profoundly impacted the geographic range and species diversity of this family. The findings indicate that such animals may be more vulnerable to the effects of human resource exploitation and climate change than initially thought.

Published in PLoS ONE, the researchers report a comprehensive genetic analysis of the yeti crabs, featuring all known species for the first time and revealing insights about their evolution. All but one of the yeti crab species are found on one of the most extreme habitats on earth, deep-sea hydrothermal vents, which release boiling-hot water into the freezing waters above above them.

The research was conducted by ecologists from Oxford's Department of Zoology, Ewha Woman's University in Seoul, South Korea and additional Chinese collaborators.

The results reveal that today's yeti crabs are likely descended from a common ancestor that inhabited deep sea hydrothermal vents on mid-ocean ridges in the SE Pacific, some time around 30-40 million years ago.

By comparing the location of current yeti crab species with their history of diversification, the authors suggest that the crustaceans likely existed in large regions of mid-ocean ridge in the Eastern Pacific, but have since gone extinct in those areas.

Discovery shows wine grapes gasping for breath

Discovery shows wine grapes gasping for breath | Gaia Diary | Scoop.it
University of Adelaide researchers have discovered how grapes "breathe," and report that shortage of oxygen leads to cell death in the grape.

The discovery raises many questions about the potentially significant impacts on grape and wine quality and flavour and vine management, and may lead to new ways of selecting varieties for warming climates.

"In 2008 we discovered the phenomenon of cell death in grapes, which can be implicated where there are problems with ripening. We've since been trying to establish what causes cell death," says Professor Steve Tyerman, Chair of Viticulture at the University of Adelaide's Waite campus.

"Although there were hints that oxygen was involved, until now we've not known of the role of oxygen and how it enters the berry."

Spring is springing earlier in polar regions than across the rest of earth

Spring is springing earlier in polar regions than across the rest of earth | Gaia Diary | Scoop.it
For every 10 degrees north from the equator you move, spring arrives about four days earlier than it did a decade ago, according to a study led by UC Davis. This is three times greater than what previous studies indicated. The authors connect such differences to more rapid warming at higher latitudes.

You've probably heard that the safety of neonicotinoid pesticides to bees is a matter of considerable controversy. However, neonicotinoids show varying toxicity to bees. Now, researchers reporting in the journal Current Biology on March 22 have new evidence in honeybees and bumble bees that helps to explain why bees differ in their sensitivity to different neonicotinoids.
