science news 14.6.2019

Today's selection of science news. Links are normally to press releases on EurekAlert (at the bottom end I may also add a couple of newspaper stories). I include quotes from the summary (using quotation marks) in cases where the title alone doesn't reveal what the story is about. My own thoughts appear without quotation marks, if I have any.

"up to four billion migrate to and from Britain each year. " - The Brexiteers will be up in arms ...

The surprising reason why some lemurs may be more sensitive to forest loss
"Scientists have given us another way to tell which endangered lemurs are most at risk from deforestation -- based on the bacteria that inhabit their guts. Researchers compared the gut microbes of 12 lemur species across the island of Madagascar, where thousands of acres of forest are cleared each year. The team found that some lemurs harbor microbes that are more specialized than others for the forests where they live."



Researchers report that the microbes living in the guts of leaf-eating lemurs like this one are largely shaped by the forests where they live, a finding that could make some species less resilient to deforestation.

The power of a love song: Dopamine affects seasonal hearing in fish and facilitates mating
"Scientists at "The Graduate Center of The City University of New York and Brooklyn College have discovered seasonal changes in dopamine levels in the female plainfin midshipman fish's inner ear helps hearing sensitivity grow in the summer mating season, making her better able to hear the male's mating calls."

cycling

On your bike?
"A James Cook University researcher says a lack of suitable roads is a big reason why cycling participation rates in Australia and Queensland are so low."
Which confirms one of many reasons why we have WNBRs this month - although in the southern hemisphere they were in March
