Published How plant cold specialists can adapt to the environment



Evolutionary biologists studied spoonworts to determine what influence genome duplication has on the adaptive potential of plants. The results show that polyploids -- species with more than two sets of chromosomes -- can have an accumulation of structural mutations with signals for a possible local adaptation, enabling them to occupy ecological niches time and time again.
Published Researchers create groundbreaking cotton quality model to aid farmers



Researchers have produced a cotton quality module -- a part of a larger forecasting tool -- allowing cotton producers to better monitor crop quality under changing environmental conditions.
Published Mapping the world's fungi from air samples



Researchers have found that the key to a quick and cost-effective mapping of biodiversity has been right in front of our eyes all along, but at the same time invisible -- i.e., in the air that surrounds us.
Published Wild plants and crops don't make great neighbors, research finds



Native plants and non-native crops do not fare well in proximity to one another, attracting pests that spread diseases in both directions, according to two new studies.
Published A new species of extinct crocodile relative rewrites life on the Triassic coastline



The surprising discovery of a new species of extinct crocodile relative from the Triassic Favret Formation of Nevada, USA, rewrites the story of life along the coasts during the first act of the Age of Dinosaurs. The new species Benggwigwishingasuchus eremicarminis reveals that while giant ichthyosaurs ruled the oceans, the ancient crocodile kin known as pseudosuchian archosaurs ruled the shores across the Middle Triassic globe between 247.2 and 237 million years ago.
Published Research reveals the most complete dinosaur discovered in the UK in a century



The most complete dinosaur discovered in the UK in the last 100 years, with a pubic hip bone the size of a 'dinner plate', has been described in a new article.
Published Not so simple: Mosses and ferns offer new hope for crop protection



Mosses, liverworts, ferns and algae may offer an exciting new research frontier in the global challenge of protecting crops from the threat of disease.
Published Wolves' return has had only small impact on deer populations in NE Washington



Wolves returned to Washington state in 2008. A new study shows that, despite their rising numbers, wolves are not having much of an impact on white-tailed deer, one of their primary prey. Scientists report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available, which is largely determined by human activity. Cougars were second in their impact. Wolves were a distant third.
Published Tackling the challenge of coca plant ID: Wild vs cultivated for cocaine



A new paper reveals that it's not as straightforward as it might seem. Despite decades of data collection by the United Nations Office on Drugs and Crime (UNODC), which has been valuable to monitor changes in areas occupied by illegal coca plantations in South America, there is no reliable scientific method to distinguish between different types of coca plants.
Published Researchers listen to the hearts of bats in flight



Unique recordings show that bats can ramp up heart rate from 6 to 900 b.p.m within minutes.
Published Archaeologists report earliest evidence for plant farming in east Africa



A trove of ancient plant remains excavated in Kenya helps explain the history of plant farming in equatorial eastern Africa, a region long thought to be important for early farming but where scant evidence from actual physical crops has been previously uncovered.
Published Study examines tree adaptability to climate change



Many trees could expand their ranges by more than 25 percent based on their potential temperature tolerances.
Published Global database reveals large gaps in our knowledge of four-footed animals



Researchers developed TetrapodTraits -- a global database of animals with four feet -- which can now be applied for better ecology, evolution and conservation research.
Published First local extinction in the US due to sea level rise, study suggests



The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published How a plant app helps identify the consequences of climate change



A research team has developed an algorithm that analyses observational data from a plant identification app. The novel approach can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.
Published Study projects major changes in North Atlantic and Arctic marine ecosystems due to climate change



New research predicts significant shifts in marine fish communities in the North Atlantic and Arctic Oceans as a result of climate warming.
Published Restored oyster sanctuaries host more marine life



Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.
Published Coral reefs: Battlegrounds for survival in a changing climate



Coral reefs, those vibrant underwater cities, stand on the precipice of collapse. While rising ocean temperatures and coral bleaching grab headlines, a new essay reveals a hidden layer of complexity in this fight for survival: the often-overlooked roles of the reefs' smallest inhabitants.
Published Wastewater is a viable medium for growing lettuce in hydroponic systems



Urban agriculture has the potential to improve food security through local, efficient, and sustainable food production. Examples of urban food systems include hydroponics, where plants grow in a nutrient solution without soil, and aquaponics, which combines hydroponics with raising fish in tanks. A new study examines the use of aquaponics wastewater as a growth medium for lettuce in a hydroponic system. This practice can potentially create a circular ecosystem for organic waste recycling and food production.
Published Climate change drives tree species towards colder, wetter regions



Climate change is likely to drive tree species towards colder and wetter regions.
