Ancestral variation guides future environmental adaptations      (via sciencedaily.com) 

The speed of environmental change is very challenging for wild organisms. When exposed to a new environment individual plants and animals can potentially adjust their biology to better cope with new pressures they are exposed to -- this is known as phenotypic plasticity. New research shows that early plasticity can influence the ability to subsequently evolve genetic adaptations to conquer new habitats.

Rapid plant evolution may make coastal regions more susceptible to flooding and sea level rise, study shows      (via sciencedaily.com) 

Evolution has occurred more rapidly than previously thought in the Chesapeake Bay wetlands, which may decrease the chance that coastal marshes can withstand future sea level rise, researchers at the University of Notre Dame and collaborators demonstrated in a recent publication in Science.

Ancient mint plants may lead to new medicines/products      (via sciencedaily.com) 

The mint family of herbs, which includes sage, rosemary, basil, and even woody plants like teak, offers an invigorating jolt to our senses of smell and taste. Researchers have found that these plants have diversified their specialized natural characteristics through the evolution of their chemistry, which could lead to potential future applications that range from medicine to pesticide production.

AI technology generates original proteins from scratch      (via sciencedaily.com) 

Scientists have created an AI system capable of generating artificial enzymes from scratch. In laboratory tests, some of these enzymes worked as well as those found in nature, even when their artificially generated amino acid sequences diverged significantly from any known natural protein.

New geosciences study shows Triassic fossils that reveal origins of living amphibians      (via sciencedaily.com) 

A team of paleontologists have discovered the first 'unmistakable' Triassic-era caecilian fossil -- the oldest-known caecilian fossils -- thus extending the record of this small, burrowing animal by roughly 35 million years. The find also fills a gap of at least 87 million years in the known historical fossil record of the amphibian-like creature.

What crocodile DNA reveals about the Ice Age      (via sciencedaily.com) 

What drives crocodile evolution? Is climate a major factor or changes in sea levels? Determined to find answers to these questions, researchers discovered that while changing temperatures and rainfall had little impact on the crocodiles' gene flow over the past three million years, changes to sea levels during the Ice Age had a different effect.

Forests face fierce threats from multiple industries, not just agricultural expansion      (via sciencedaily.com) 

Intact forests are important climate regulators and harbors of biodiversity, but they are rapidly disappearing. Agriculture is commonly considered to be the major culprit behind forest loss, but the authors of a new article show that agriculture isn't solely to blame. For forest loss associated with the 2014 world economy, over 60% was related to final consumption of non-agricultural products, such as minerals, metals and wood-related goods, and the authors argue that we must consider international trade markets when designing conservation strategies.

Collision risk and habitat loss: Wind turbines in forests impair threatened bat species      (via sciencedaily.com) 

In order to meet climate protection goals, renewable energies are booming -- often wind power. More than 30,000 turbines have already been installed on the German mainland so far, and the industry is currently scrambling to locate increasingly rare suitable sites. Thus, forests are coming into focus as potential sites. A scientific team has now demonstrated that wind turbines in forests impair endangered bat species: Common noctules (Nyctalus noctula), a species with a high risk of colliding with rotor blades, are attracted to forest wind turbines if these are located near their roosts. Far from roosts, common noctules avoid the turbines, essentially resulting in a loss of foraging space and thus habitat for this species.

DNA from domesticated chickens is tainting genomes of wild red junglefowl, study finds      (via sciencedaily.com) 

The red junglefowl -- the wild ancestor of the chicken -- is losing its genetic diversity by interbreeding with domesticated birds, according to a new study.

Plague trackers: Researchers cover thousands of years in a quest to understand the elusive origins of the Black Death      (via sciencedaily.com) 

Seeking to better understand more about the origins and movement of bubonic plague, in ancient and contemporary times, researchers have completed a painstaking granular examination of hundreds of modern and ancient genome sequences, creating the largest analysis of its kind.

Black-legged tick genome deciphered      (via sciencedaily.com) 

Scientists have deciphered a comprehensive, continuous genome for a parasite responsible for transmitting Lyme disease and other serious infections to hundreds of thousands of Americans yearly. With their newly described genome for the black-legged tick, or deer tick, the researchers identified thousands of novel genes and new protein functions, including proteins associated with tick immunity, disease transmission and developmental stages.

Our future climate depends partly on soil microbes -- but how are they affected by climate change?      (via sciencedaily.com)     Original source 

The largest terrestrial carbon sink on Earth is the planet's soil. One of the big fears is that a warming planet will liberate significant portions of the soil's carbon, turning it into carbon dioxide (CO2) gas, and so further accelerate the pace of planetary warming. A key player in this story is the microbe, the predominant form of life on Earth, and which can either turn organic carbon -- the fallen leaves, rotting tree stumps, dead roots and other organic matter -- into soil, or release it into the atmosphere as CO2. Now, an international team of researchers has helped to untangle one of the knottiest questions involving soil microbes and climate change: what effect does a warming planet have on the microbes' carbon cycling?

Madagascar mouse lemur retroviruses are diverse and surprisingly similar to ones found in polar bears or domestic sheep      (via sciencedaily.com) 

Madagascar is home to a unique biodiversity with a large number of endemic species, among those many lemur species, including the mouse lemurs. This diversity is also found in their retroviruses. Biologists analyzed the mouse lemur genome and identified viruses of two classes that represent ancient infections of the mouse lemur germline. The viruses now behave similarly to lemur genes and are thus called endogenous retroviruses (ERVs). It was surprising that some of the identified retroviruses are closely related to viruses found in other, very different mammals such as polar bears or domestic sheep. This suggests an intriguing and complex pattern of host switching of retroviruses, much more complex than previously thought.

How crocs can go hours without air: Crocodilian hemoglobin      (via sciencedaily.com) 

The crocodilian edition of hemoglobins -- the scuba tanks of the blood -- work so well that crocs can go hours without air. The hyper-efficiency of that adaptation has led some biologists to wonder why, of all the jawed vertebrates, crocodilians were the lone group to hit on such an optimal solution to making the most of a breath. After resurrecting the hemoglobin of ancient crocodilian ancestors, a team may have an answer.

Researchers describe five new deep-sea squat lobster species. Combining molecular data and microCT their findings show a wider species distribution range and shallower genetic diversity, calling for a revision of the current classification of squat lobsters.

Landscaping for drought: We're doing it wrong      (via sciencedaily.com)     Original source 

Despite recent, torrential rains, most of Southern California remains in a drought. Accordingly, many residents plant trees prized for drought tolerance, but a new study shows that these trees lose this tolerance once they're watered.

It would take 23 million years for evolution to replace Madagascar's endangered mammals      (via sciencedaily.com) 

90% of the plants and animals on Madagascar are found nowhere else on Earth, but this treasure trove of evolution is under serious threat due to habitat loss, over-hunting, and climate change. In this study, researchers examined how long it took Madagascar's unique modern mammal species to emerge and estimated how long it would take for a similarly complex set of new mammal species to evolve in their place if the endangered ones went extinct: 23 million years, far longer than scientists have found for any other island.
