Climate change coping mechanism discovered in humble algae      (via sciencedaily.com)     Original source 

One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental conditions, such as ocean warming and even the reduction in the productivity of crops.

200-year-old DNA helps map tiny fly's genetic course to new lands, modern times      (via sciencedaily.com)     Original source 

Researchers have extracted and analyzed DNA from fruit flies housed in museum collections in Lund, Stockholm and Copenhagen. Surprisingly, the researchers found the fruit flies collected in Sweden in the early 1800s were more genetically similar to 21st century flies than the Swedish samples from the 1930s.

Honey bees may inherit altruistic behavior from their mothers      (via sciencedaily.com)     Original source 

True altruism is rare behavior in animals, but a new study has found that honey bees display this trait. Additionally, they found that an evolutionary battle of genetics may determine the parent they inherit it from.

Win-win in muscle research: Faster results and fewer laboratory animals thanks to new method      (via sciencedaily.com)     Original source 

To study muscle diseases, scientists rely on the mouse as a model organism. Researchers have now developed a new method that is not only faster and more efficient than conventional ones but also greatly reduces the number of experimental animals needed for studying the function of genes in muscle fibers.

Killer whales' diet more important than location for pollutant exposure      (via sciencedaily.com)     Original source 

Both elegant and fierce, killer whales are some of the oceans' top predators, but even they can be exposed to environmental pollution. Now, in the largest study to date on North Atlantic killer whales, researchers report the levels of legacy and emerging pollutants in 162 individuals' blubber. The animals' diet, rather than location, greatly impacted contaminant levels and potential health risks -- information that's helpful to conservation efforts.

Not lazy at all: Honey bee drones      (via sciencedaily.com)     Original source 

Sometimes it is worthwhile to look at the details, to study aspects that seem to be uninteresting or were previously ignored, and see noteworthy phenomena come to light. Researchers showed that male honey bees (drones), long considered lazy, are (at times) the most active members of the colony.

Epiphytes, amazing plants like moss and bromeliads found in trees, face growing threats      (via sciencedaily.com)     Original source 

Epiphytes, plants such as orchids and mosses that grow in trees, draw nutrients from the air and create refuge for all sorts of other life forms. They are the foundation of forest canopy ecosystems, but they are facing threats from human and natural disturbances.

Death is only the beginning: Birds disperse eaten insects' eggs      (via sciencedaily.com)     Original source 

Relationship patterns among flightless stick insects suggest that birds disperse the eggs after eating gravid females. Lab experiments previously suggested the possibility, but a new genetic analysis of natural populations in Japan now supports the idea.

Tropical ecosystems more reliant on emerging aquatic insects, study finds, potentially putting them at greater risk      (via sciencedaily.com)     Original source 

Researchers have found that tropical forest ecosystems are more reliant on aquatic insects than temperate forest ecosystems, making them more vulnerable to disruptions to the links between land and water. This is a significant finding, as tropical forests play a vital role in global biodiversity and climate regulation. The study's authors warn that any disruption to the land-water connections in these ecosystems could have serious consequences for their health and resilience.

Newly-discovered 'margarita snails' from the Florida Keys are bright lemon-yellow      (via sciencedaily.com)     Original source 

A newly-discovered, bright yellow snail has been discovered in the Florida Keys and named in honor of Jimmy Buffet's song 'Margaritaville.' The lemon-colored marine snail, along with its lime-green cousin from Belize, is the subject of a recent study ; researchers think these snails' bright colors might help deter predators.

Space weather disrupts nocturnal bird migration, study finds      (via sciencedaily.com)     Original source 

It's well-known that birds and other animals rely on Earth's magnetic field for long-distance navigation during seasonal migrations. But how do periodic disruptions of the planet's magnetic field, caused by solar flares and other energetic outbursts, affect the reliability of those biological navigation systems?

Consistent metabolism may prove costly for insects in saltier water      (via sciencedaily.com)     Original source 

Increased salinity usually spells trouble for freshwater insects like mayflies. A new study finds that the lack of metabolic responses to salinity may explain why some freshwater insects often struggle in higher salinity, while other freshwater invertebrates (like mollusks and crustaceans) thrive.

Bewick's swans choose wintering areas based on the weather      (via sciencedaily.com)     Original source 

Bewick’s swans fly less far during their autumn migration when the weather is warm. Climate change has therefore led to a shift in their common wintering areas. Now, for the first time, bird researchers have been able to use long-term GPS data to pinpoint the specific choices that individual swans make.
