Bloodsucking pests like bat fleas and bat flies may not sound very appealing to the rest of us, but to University at Buffalo biologist Katharina Dittmar de la Cruz, Ph.D., they are among the most successful creatures evolution has ever produced.
The hardiest plants and those most likely to survive the climatic shifts brought about by global warming are now easier to identify, thanks to new research findings by a team from Queen’s University. Plants existing at the edges of their natural habitats may enhance survival of the species during global warming, says Queen’s University professor.
For the first time, researchers have shown that the pre-hatching calls of baby Nile crocodiles actually mean something to their siblings and to their mothers. The calls–which are perfectly audible to humans and sound like “umph! umph! umph!”–tell the others in the nest that it’s time to hatch, according to the report in the June 23rd issue of Current Biology. Those cries also tell the mother croc to start digging up the nest.
No-take marine reserves, in which fishing is completely banned, can lead to very rapid comebacks of the fish species most prized by commercial and recreational fisheries, reveals a new study of Australia’s Great Barrier Reef published in the June 24th issue of Current Biology.
