Soil microbes help plants cope with drought, but not how scientists thought      (via sciencedaily.com)     Original source 

In a multi-generation experiment, researchers found microbes helped plants cope with drought, but not in response to plants' cries for help. Instead, the environment itself selected for drought-tolerant microbes. And while those hardy microbes were doing their thing, they just happened to make plants more drought-tolerant, too.

Missing island explains how endemic species on the Miyako Islands emerged      (via sciencedaily.com)     Original source 

Miyako Islands are home to various native species of snake and lizards. How these species came to call these islands home has long puzzled scientists. A group of researchers have compiled the latest geological and biological data, proposing that an island once facilitated migration between Okinawa and Miyako Islands.

Forgotten tropical plants rediscovered after 100-plus years with the help of community science      (via sciencedaily.com)     Original source 

Deep in the tropical Andes, a genus called Nasa harbored elusive and forgotten plant species. Through the collaborative efforts of botanists and citizen scientists on iNaturalist, these plants have been rediscovered after decades, some even after more than a century.

Spurge purge: Plant fossils reveal ancient South America-to-Asia 'escape route'      (via sciencedaily.com)     Original source 

Newly identified plant fossils found in Argentina suggest that a group of spurges long thought to have Asian origins may have first appeared in Gondwanan South America.

Study improves understanding of how bacteria benefit plant growth      (via sciencedaily.com)     Original source 

Scientists have found that competition between strains of beneficial bacteria in the soil degrades the service that the bacteria provide to their hosts.

Miocene period fossil forest of Wataria found in Japan      (via sciencedaily.com)     Original source 

An exquisitely preserved fossil forest from Japan provides missing links and helps reconstruct a whole Eurasia plant from the late Miocene epoch.

The genetic changes that made it possible for humans to walk upright have been uncovered in a study that also shows how slight variations in skeletal proportions are linked to arthritis.

Engineering plants for a changing climate      (via sciencedaily.com)     Original source 

Climate change is affecting the types of plant varieties we can cultivate, as well as how and where we can do so. A new collection of articles in the open access journal PLOS Biology explores the twin challenges of engineering plants for resilience to climate change and enhancing their carbon-capture potential.

Shark shock: Scientists discover filter-feeding basking sharks are warm-bodied like great whites      (via sciencedaily.com)     Original source 

Approximately 99.9% of fish and shark species are 'cold-blooded', meaning their body tissues generally match the temperature of the water they swim in -- but researchers have just discovered the mighty basking shark is a one-in-a-thousand exception. Instead, these sharks keep the core regions of their bodies warmer than the water like the most athletic swimmers in the sea such as great white sharks, mako sharks and tuna.

Paleontologists identify two new species of sabertooth cat      (via sciencedaily.com)     Original source 

Sabertooth cats make up a diverse group of long-toothed predators that roamed Africa around 6-7 million years ago, around the time that hominins -- the group that includes modern humans -- began to evolve. By examining one of the largest global Pliocene collections of fossils in Langebaanweg, north of Cape Town in South Africa, researchers present two new sabertooth species and the first family tree of the region's ancient sabertooths. Their results suggest that the distribution of sabertooths throughout ancient Africa might have been different than previously assumed, and the study provides important information about Africa's paleoenvironment.

Flying reptiles had nurturing parental style      (via sciencedaily.com)     Original source 

Did the pterosaurs, flying reptiles from the days of the dinosaurs, practice parental care or not? New research shows that pterosaurs were indeed caring parents -- but only the larger species.

Unusual fossil shows rare evidence of a mammal attacking a dinosaur      (via sciencedaily.com)     Original source 

Scientists have described an unusual fossil from around 125 million years ago in China that shows a dramatic moment in time when a carnivorous mammal attacked a larger plant-eating dinosaur. The two animals are locked in mortal combat, and it's among the first evidence to show actual predatory behavior by a mammal on a dinosaur. The fossil's presence challenges the view that dinosaurs had few threats from their mammal contemporaries during the Cretaceous, when dinosaurs were the dominant animals.

Picky green sea turtle has travelled to the same place to eat for generations      (via sciencedaily.com)     Original source 

For approximately 3,000 years, generations of green sea turtles have returned to the same seagrass meadows to eat. The fact that this stretches over many generations highlights the importance of protecting seagrass meadows along the coasts of North Africa.

In Florida, endangered coral finds a way to blossom      (via sciencedaily.com)     Original source 

In a new study, researchers have found that the restoration efforts of the critically endangered species elkhorn coral depend largely on the animal's location, microbiome, and the right conditions to provide an abundance of food.

Form and function of island and mainland plants      (via sciencedaily.com)     Original source 

Oceanic islands provide useful models for ecology, biogeography and evolutionary research. Many ground-breaking findings -- including Darwin's theory of evolution -- have emerged from the study of species on islands and their interplay with their living and non-living environment. Now, an international research team has investigated the flora of the Canary Island of Tenerife. The results were surprising: the island's plant-life exhibits a remarkable diversity of forms. But the plants differ little from mainland plants in functional terms. However, unlike the flora of the mainland, the flora of Tenerife is dominated by slow-growing, woody shrubs with a 'low-risk' life strategy.

Colonization influences worldwide distribution of plant specimens      (via sciencedaily.com)     Original source 

Plant diversity in nature is generally highest in tropical regions around the equator, with decreasing diversity closer to the poles. Researchers now show that the plant specimens housed in herbaria in Europe and North America are more comprehensive and diverse than the collections housed in the countries with more natural plant diversity.

Multiple uses of tropical mosaic landscapes      (via sciencedaily.com)     Original source 

Many landscapes in the tropics consist of a mosaic of different types of land use. How people make use of these different ecosystems, with their particular plant communities, was unclear until now. Researchers, many of them from Madagascar, have now investigated this. When considering biodiversity, forests often get the most attention. But this research shows that rural households use a wide range of plant species and services provided by many nearby ecosystem types.

New fossil flying reptile 'Elvis' takes flight      (via sciencedaily.com)     Original source 

In an exciting scientific development, an international team of researchers have officially named a newly discovered 145-million-year-old pterosaur. The animal had enormous 2-meter wingspan and was nicknamed 'Elvis' when the fossil was first unearthed in Bavaria, Germany because of the giant pompadour-like bony crest on its skull. Now the animal has been given a formal scientific name of Petrodactyle wellnhoferi. The name translates as 'Wellnhofer's stone-finger' honouring legendary German palaeontologist Peter Wellnhofer who spent his career working on German pterosaurs. Petrodactyle is a very complete skeleton with nearly every bone preserved and in remarkable detail.

Crawford Lake, Canada, chosen as the primary marker to identify the start of the Anthropocene epoch      (via sciencedaily.com)     Original source 

An international team of researchers has chosen the location which best represents the beginnings of what could be a new geological epoch, the Anthropocene. The Anthropocene Working Group have put forward Crawford Lake, in Canada, as a Global Boundary Stratotype Section and Point (GSSP) for the Anthropocene. A GSSP is an internationally agreed-upon reference point to show the start of a new geological period or epoch in layers of rock that have built up through the ages.
