Genomic insights: How female butterflies alter investment in attractiveness vs. fecundity
By analyzing the genomes of orange and white females of the clouded yellow butterfly, researchers have identified the location and key components of an alternative life history switch that is only expressed in females
Southern white rhinos are threatened by incest and habitat fragmentation
Targeted measures can help to avert this danger
Connecting the prehistoric past to the global future
Research on global biodiversity has long assumed that present-day biodiversity patterns reflect present-day factors, namely contemporary climate and human activities. A new study shows that climate changes and human impacts over the last 100,000 years continue to shape patterns of…

Leaving home is beneficial for male squirrels but not for females, study shows
New research shows that male squirrels who move outside of the population they were born to live longer and have more offspring.

Climate cycles and insect pests drive migration timing of reindeer’s North American cousin
In the largest-ever caribou study a University of Maryland-led team disputes long-held assumptions about migration timing and suggests warming summers may negatively affect calving.

Understanding Asteraceae: Validation of a Hyb-Seq probe set for evolutionary studies
Accurately reconstructing the relationships between different species requires analyzing the sequences of a judiciously selected, and preferably large, sample of different genes. Hybrid capture with high-throughput sequencing, or Hyb-Seq, is a powerful tool for obtaining those gene sequences, but must…
Study to help manage shark populations in Pacific Panama
Sharks play a critical role in keeping oceans healthy, balancing the food chain and ensuring species diversity. However, the demand for shark derivatives has led to their exploitation, often without appropriate management strategies in place. In an assessment of Pacific…
New research pinpoints which of the world’s trees are climate-ready
Botanists from Trinity College Dublin have discovered that “penny-pinching” evergreen species such as Christmas favourites, holly and ivy, are more climate-ready in the face of warming temperatures than deciduous “big-spending” water consumers like birch and oak. As such, they are…
Deciphering the equations of life
A new theory describes what all animals have in common and allows predictions for organisms that might not be well understood by science.

Harbor porpoise calves exposed to neurotoxic PCBs in mothers’ milk
New ZSL study reveals mothers detoxify themselves by passing on most neurotoxic PCBs through lactation
Svalbard reindeer populations rebounding from centuries of hunting
Most reindeer and caribou populations are on the decline; that’s not the case for reindeer living close to the North Pole
In hunted rainforests, termites lose their dominance
Rice ecologists see sharp reduction in insect ‘engineers’ when elephants, other large animals disappear

Climate change and human activities threatens picky penguins
Eating a krill-only diet has made one variety of Antarctic penguin especially susceptible to the impacts of climate change, according to new research involving the University of Saskatchewan (USask) which sheds new light on why some penguins are winners and…
E4 Ecography Award for Ludmilla Figueiredo
Calcareous grasslands are dry, nutrient-poor habitats that occur frequently in the north of Bavaria. They are home to orchids, snakes and rare insects. Like all other ecosystems on earth, these grasslands are constantly threatened by disturbances – for example from…

Forests face climate change tug of war
In a world of rising levels of atmospheric carbon dioxide, plants should be happy, right? Experiments have shown that, yes, increased carbon dioxide does allow plants to photosynthesize more and use less water. But the other side of the coin…

UT mathematician develops model to control spread of aquatic invasive species
Adjusting the water flow rate in a river can prevent invasive species from moving upstream and expanding their range. An applied mathematician at UT has developed a partial differential equation model to find the desired flow rate to reduce invasive…
Only eat oysters in months with an ‘r’? Rule of thumb is at least 4,000 years old
GAINESVILLE, Fla. — Foodie tradition dictates only eating wild oysters in months with the letter “r” – from September to April – to avoid watery shellfish, or worse, a nasty bout of food poisoning. Now, a new study suggests people…
A decade after the predators have gone, Galapagos Island finches are still being spooked
On some of the Galapagos Islands where human-introduced predators of Darwin’s finches were eradicated over a decade ago, the finches are still acting as though they are in danger, according to research published today in the Journal of Animal Ecology…
