Published How an African bird might inspire a better water bottle
(via sciencedaily.com) Original source An extreme closeup of feathers from a bird with an uncanny ability to hold water while it flies could inspire the next generation of absorbent materials.
Published Perfume component helps lure male moth pests
(via sciencedaily.com) Original source A small amount of a perfume component -- nonanal -- added to a traditional blend of sex pheromones captures the attention of male fall armyworm moths looking for a good time.
Published Light pollution may extend mosquitoes' biting season
(via sciencedaily.com) Original source A new study's finding that urban light pollution may disrupt the winter dormancy period for mosquitoes that transmit West Nile virus could be considered both good news and bad news. The good news is that the disease-carrying pests may not survive the winter if their plans to fatten up are foiled. The bad news is their dormancy period, known as diapause, may simply be delayed -- meaning they're biting humans and animals longer into the fall.
Published Male yellow crazy ants are real-life chimeras
(via sciencedaily.com) Original source Researchers discovered that males of the yellow crazy ant have maternal and paternal genomes in different cells of their body and are thus chimeras.
Published Migratory birds can partially offset climate change
(via sciencedaily.com) Original source A new study demonstrates that birds can partially compensate for climate change by delaying the start of spring migration and completing the journey faster. But the strategy comes with a cost -- a decline in overall survival.
Published Scientists advocate for integration of biogeography and behavioral ecology to rapidly respond to biodiversity loss
(via sciencedaily.com) Original source An interdisciplinary team of researchers is advocating for convergent research that integrates the fields of biogeography and behavioral ecology to more rapidly respond to challenges associated with climate change and biodiversity loss.
Published What is it good for? Absolutely one thing: Luna moths use their tails solely for bat evasion
(via sciencedaily.com) Original source Scientists recently discovered that Luna moths use their long tails as decoys to throw bats off their trail. But their tails also make Luna moths might also make them stand out to potential mates and make them more conspicuous to lurking predators. A pair of complementary studies looked to see whether these colorful, bat-deflecting appendages might come with any additional costs or benefitt
Published Scientists show how we can anticipate rather than react to extinction in mammals
(via sciencedaily.com) Original source Most conservation efforts are reactive. Typically, a species must reach threatened status before action is taken to prevent extinction, such as establishing protected areas. A new study shows that we can use existing conservation data to predict which currently unthreatened species could become threatened and take proactive action to prevent their decline before it is too late.
Published Engineered plants produce sex perfume to trick pests and replace pesticides
(via sciencedaily.com) Original source Tobacco plants have been engineered to manufacture an alluring perfume of insect sex pheromones, which could be used to confuse would-be pests looking for love and reduce the need for harmful pesticides.
Published Here's how a worm's embryonic cells changed its development potential
(via sciencedaily.com) Original source Researchers have spotted how specific proteins within the chromosomes of roundworms enable their offspring to produce specialized cells generations later, a startling finding that upends classical thinking that hereditary information for cell differentiation is mostly ingrained within DNA and other genetic factors.
Published In Florida study, nonnative leaf-litter ants are replacing native ants
(via sciencedaily.com) Original source A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants -- even in protected natural areas of the state, researchers report.
Published Environmental impact reports hugely underestimate consequences for wildlife
(via sciencedaily.com) Original source Research shows that environmental impact reports hugely underestimate the consequences of new developments for wildlife. This is because they don't take into account how birds and other animals move around between different sites. The research shows how a planned airport development in Portugal could affect more than 10 times the number of Black-tailed Godwits estimated in a previous Environmental Impact Assessment. The team have been studying these Godwits across Europe for over 30 years but they say that any species that moves around is likely to be under-represented by such reports.
Published Sierra squirrels find their niche amid a changing climate
(via sciencedaily.com) Original source A new study of squirrels in California's Sierra Nevada mountains finds that climate is just one factor impacting where species make their homes in a changing world.
Published Newly discovered probiotic could protect Caribbean corals threatened by deadly, devastating disease
(via sciencedaily.com) Original source Researchers have discovered the first effective bacterial probiotic for treating and preventing stony coral tissue loss disease (SCTLD), a mysterious ailment that has devastated Florida's coral reefs since 2014 and is rapidly spreading throughout the Caribbean. The probiotic treatment provides an alternative to the use of the broad-spectrum antibiotic amoxicillin, which has so far been the only proven treatment for the disease but which runs the risk of promoting antibiotic-resistant bacteria.
Published Coral skeletons influence reef recovery after bleaching
(via sciencedaily.com) Original source Natural disasters can devastate a region, abruptly killing the species that form an ecosystem's structure. But how this transpires can influence recovery. While fires scorch the landscape to the ground, a heatwave leaves an army of wooden staves in its wake. Storm surges and coral bleaching do something similar underwater.
Published Lifting the veil on disease avoidance strategies in multiple animal species
(via sciencedaily.com) Original source A framework has been developed to test disgust and its associated disease avoidance behaviors across various animal species, social systems, and habitats. Over 30 species have been predicted to exhibit disease avoidance strategies in the wild. With these predictions, the team accounts for models of specific ecological niches, sensory environments and social systems for a number of species including the native common octopus and the invasive red-eared slider, which are both relevant to Japan.
Published New tool shows progress in fighting spread of invasive grass carp in Great Lakes
(via sciencedaily.com) Original source Researchers created a new way to estimate the abundance of invasive 'sleeper' species in freshwater ecosystems and help guide management strategies.
Published Lab-grown fat could give cultured meat real flavor and texture
(via sciencedaily.com) Original source Researchers have successfully bulk-produced fat tissue in the lab that has a similar texture and make-up to naturally occurring fats from animals.
Published Red tide warning system
(via sciencedaily.com) Original source Current methods to monitor red tide are limited. Using AUTOHOLO, a new autonomous, submersible, 3D holographic microscope and imaging system, a study is the first to characterize red tide in the field and breaks new ground for monitoring harmful algal blooms.
Published Elephants as a new model for understanding human evolution
(via sciencedaily.com) Original source Human culture and language may be the result of 'self-domestication': an evolutionary process that leads to less aggressive and more prosocial individuals. A research team argues that elephants -- like humans and bonobos -- may also be self-domesticated. Elephants show many traits associated with self-domestication, such as prosocial behavior, playfulness and complex communication skills. This makes elephants an interesting new animal model for the evolution of prosociality.
