Butterflies fly during the day while moths travel at night - or so you might think. In reality, their behavior is much more complicated. A new Florida Museum of Natural History study offers the first comprehensive overview of the surprisingly complex question of when butterflies and moths are active.
There are mostly benign species in the soil-borne, plant-associated genus of bacteria known as Rhodococcus, but a few species can be pathogenic. A team of researchers at Oregon State University used genome sequencing to identify species of Rhodococcus that transition between beneficial and pathogenic -- stimulating growth in some plants in the former case while deforming tissues in the latter.
One of the world's 7,000 languages vanishes every other week, and half might not survive the 21st century, experts say. To preserve as much linguistic diversity as possible in the face of this threat, McGill University scientists are proposing to borrow a leaf from conservation biology by using language trees to help guide efforts to preserve linguistic diversity.
Everyone wants to be with their family for Christmas, but spare a thought for a group of orphan fossils that have been separated from their parents since the dawn of animal evolution, over half a billion years ago.
Agriculture and domestic activities consume much of the Colorado River water that once flowed to the Colorado Delta and Northern Gulf of California. The nature and extent of impact of this fresh-water loss on the ecology and fisheries of the Colorado Delta and Gulf of California is controversial. A recent publication in the journal PeerJ reveals a previously unseen risk to the unique local biodiversity of the tidal portion of the Delta.
Fossilized ticks discovered trapped and preserved in amber show that these parasites sucked the blood of feathered dinosaurs almost 100 million years ago, according to a new article published in Nature Communications today.
A study by the University of Cincinnati found that the rare Henst's goshawk of Madagascar hunts lemurs in low-lying areas that are most at risk to deforestation. Researchers could use this isotope analysis to study the habitat and prey needs of other threatened species that are difficult to track.
Concerns about biodiversity tend to focus on the loss of species, but a new study suggests that the loss of variation within species can also have important and unexpected consequences on the environment.
Global climate warming is considered a major threat to many living organisms but not all consequences of warming need to be harmful to species. A recent study from the University of Helsinki published on Evolution shows that two bird species react differently to warmer spring temperatures, succeeding to mitigate negative effects of competition and mixed breeding.
Three billion years ago, the sun shone weaker, but Earth stayed surprisingly warm. Carl Sagan thought a greenhouse effect must have been to thank. A model built on 359 chemical processes has finally arrived at scenarios with a reasonable chance of producing the needed methane on ancient Earth. The model has broad parameters in hope that it may someday be of use to interpret conditions on exoplanets.
