Wild Asian elephants display unique puzzle solving skills      (via sciencedaily.com)     Original source 

A new study has documented the abilities of individual wild Asian elephants to access food by solving puzzles that unlocked storage boxes. It is the first research study to show that individual wild elephants have different willingness and abilities to problem solve in order to get food.

Boo to a goose -- new animal behaviour tech aims to save wildlife      (via sciencedaily.com)     Original source 

Facial recognition software used to study the social behavior of individual Greylag Geese in Europe will soon be used to monitor one of the rarest geese in the world, the Cape Barren Goose in South Australia. The technology was used to assess how each bird responds to images of themselves, other flock mates or partners and researchers say it could be used by other scientists or in citizen science apps around the world to monitor and record endangered wildlife or even to promote the welfare of animals in captivity.

Caribbean parrots thought to be endemic are actually relicts of millennial-scale extinction      (via sciencedaily.com)     Original source 

For the first time, researchers have extracted ancient DNA from Caribbean parrot fossils and archaeological specimens, showing that species thought to be endemic to particular islands were historically more widespread and diverse.

AI increases precision in plant observation      (via sciencedaily.com)     Original source 

Artificial intelligence (AI) can help plant scientists collect and analyze unprecedented volumes of data, which would not be possible using conventional methods. Researchers have now used big data, machine learning and field observations in the university's experimental garden to show how plants respond to changes in the environment.

How climate warming could disrupt a deep-rooted relationship      (via sciencedaily.com) 

Trees depend on fungi for their well-being. As climate change and global warming cause higher temperatures and amplified drought, little is known about how these important fungi will respond. To investigate this issue, a research team conducted a climate change experiment where they exposed boreal and temperate tree species to warming and drought treatments to better understand how fungi and their tree hosts respond to environmental changes. Their findings revealed that the combined effects of warming and water stress will likely result in major disturbances of ectomycorrhizal networks and may harm forest resilience and function.

Understanding the sex life of coral gives hope of clawing it back from the path to extinction      (via sciencedaily.com)     Original source 

Scientists have mapped the reproductive strategies and life cycle of an endangered coral species, the purple cauliflower soft coral Dendronephthya australis. Lab-grown larvae have been successfully introduced back into the wild.

Monkeys cause a stink in response to human noise      (via sciencedaily.com)     Original source 

New research has found that monkeys increase their use of scent markings to compensate for human noise pollution. The study has investigated how primates change their communication strategies in response to noise pollution. The researchers studied endangered pied tamarins (Saguinus bicolor), which use both vocal calls and scent markings. The researchers found that the frequency of scent marking directly increased in line with noise decibel levels.

Urban light pollution linked to smaller eyes in birds      (via sciencedaily.com)     Original source 

The bright lights of big cities could be causing an evolutionary adaptation for smaller eyes in some birds, a new study indicates. Researchers found that two common songbirds, the Northern Cardinal and Carolina Wren, that live year-round in the urban core of San Antonio, Texas, had eyes about 5% smaller than members of the same species from the less bright outskirts. Researchers found no eye-size difference for two species of migratory birds, the Painted Bunting and White-eyed Vireo, no matter which part of the city they lived in for most of the year. The findings have implications for conservation efforts amid the rapid decline of bird populations across the U.S.

Behavior is the secret to success for a range expansion      (via sciencedaily.com)     Original source 

While many species are undergoing drastic declines in their numbers and geographic ranges, other species seem to be thriving. Researchers investigating the great-tailed grackle, a bird that has been establishing new populations across North America in the past few decades, reveal that behavior might play a key role in their success. They found that the population on the range's edge is more persistent and has more variability in flexibility, and that this species has shifted toward living more in urban, arid environments.

Researchers issue urgent call to save the world's largest flower -Rafflesia -- from extinction      (via sciencedaily.com)     Original source 

A new study finds that most Rafflesia species, which produce the world's largest flowers, face extinction. Lack of protection at local, national, and international levels means that remaining populations are under critical threat.

Range of pesticides, including neonicotinoids, found in pollen of different bee species      (via sciencedaily.com)     Original source 

New research paints a worrying picture for the different species of bees that provide multi-million-euro pollination services in Ireland each yea. The work raises concerns about the potential wide-spread exposure to multiple chemicals from two pesticide categories (fungicides and neonicotinoid insecticides) and indicates that different bee species may be exposed differently to pesticides -- meaning that assessments of pesticide risk to honey bees may not be easily extrapolated to other bees.

RNA for the first time recovered from an extinct species      (via sciencedaily.com)     Original source 

A new study shows the isolation and sequencing of more than a century-old RNA molecules from a Tasmanian tiger specimen preserved at room temperature in a museum collection. This resulted in the reconstruction of skin and skeletal muscle transcriptomes from an extinct species for the first time. The researchers note that their findings have relevant implications for international efforts to resurrect extinct species, including both the Tasmanian tiger and the woolly mammoth, as well as for studying pandemic RNA viruses.

Almost half of koala habitats will be under high bushfire threat by 2070      (via sciencedaily.com) 

The research team generated a series of fire susceptibility maps. These show the proportion of Australia experiencing 'high' or 'very high' fire susceptibility increasing from 14.9% now to 15.66% by 2070 -- while fire susceptibility of areas suitable for the plants that koalas depend on is tipped to jump from 39.56% to 44.61% by 2070.
