How did humans learn to walk? New evolutionary study offers an earful      (via sciencedaily.com)     Original source 

A new study, which centers on evidence from skulls of a 6-million-year-old fossil ape, Lufengpithecus, offers important clues about the origins of bipedal locomotion courtesy of a novel method: analyzing its bony inner ear region using three-dimensional CT-scanning. The inner ear appears to provide a unique record of the evolutionary history of ape locomotion.

Scientists develop novel method to estimate biodiversity loss in Singapore over the past two centuries      (via sciencedaily.com)     Original source 

Scientists have employed novel statistical methods to reveal the extent of biodiversity loss in Singapore over the past two centuries. The study paints the most accurate picture to date of the ecological impact of deforestation and urban development in the tropical city-state. From a comprehensive dataset, the study estimated that Singapore has lost 37 per cent of its species.

Researchers map genome for cats, dolphins, birds, and dozens of other animals      (via sciencedaily.com)     Original source 

Researchers mapped genetic blueprints for 51 species including cats, dolphins, kangaroos, penguins, sharks, and turtles, a discovery that deepens our understanding of evolution and the links between humans and animals. The researchers developed novel algorithms and computer software that cut the sequencing time from months -- or decades in the case of the human genome -- to a matter of days.

Use it or lose it: How seagrasses conquered the sea      (via sciencedaily.com)     Original source 

Seagrasses provide the foundation of one of the most highly biodiverse, yet vulnerable, coastal marine ecosystems globally. They arose in three independent lineages from their freshwater ancestors some 100 million years ago and are the only fully submerged, marine flowering plants. Moving to such a radically different environment is a rare evolutionary event and definitely not easy. How did they do it? New reference quality genomes provide important clues with relevance to their conservation and biotechnological application.

Ancient brown bear genomes sheds light on Ice Age losses and survival      (via sciencedaily.com)     Original source 

The brown bear is one of the largest living terrestrial carnivores, and is widely distributed across the Northern Hemisphere. Unlike many other large carnivores that went extinct at the end of the last Ice Age (cave bear, sabretoothed cats, cave hyena), the brown bear is one of the lucky survivors that made it through to the present. The question has puzzled biologists for close to a century -- how was this so?

Study offers rare long-term analysis of techniques for creating standing dead trees for wildlife habitat      (via sciencedaily.com)     Original source 

Ecologists have long known that standing dead trees, commonly referred to as snags, are an important habitat element for forest dwellers and act as a driver of biodiversity. They're so important that in some managed forests, snag creation is part of the conservation tool kit -- i.e., crews sometimes convert a percentage of live trees into dead ones through techniques ranging from sawing off their tops to wounding their trunks to injecting them with disease-causing fungi.

A new perspective on the temperature inside tropical forests      (via sciencedaily.com)     Original source 

New worldwide maps of temperatures inside tropical forests show that global warming affect different way in different parts of the forests. Undergrowth level temperature of the tropical forests can be even 4 degrees less than average temperature of the area.

Complex green organisms emerged a billion years ago      (via sciencedaily.com)     Original source 

Of all the organisms that photosynthesize, land plants have the most complex form. How did this morphology emerge? A team of scientists has taken a deep dive into the evolutionary history of morphological complexity in streptophytes, which include land plants and many green algae. Their research allowed them to go back in time to investigate lineages that emerged long before land plants existed.

Wolves and elk are (mostly) welcome back in Poland and Germany's Oder Delta region, survey shows      (via sciencedaily.com)     Original source 

An online survey conducted in Germany and Poland shows that large parts of the participants support the return of large carnivores and herbivores, such as wolves and elk, to the Oder Delta region. Presented with different rewilding scenarios, the majority of survey participants showed a preference for land management that leads to the comeback of nature to the most natural state possible. Locals, on the other hand, showed some reservations.

A window into plant evolution: The unusual genetic journey of lycophytes      (via sciencedaily.com)     Original source 

An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study reveals that these plants have maintained a consistent genetic structure for over 350 million years, a significant deviation from the norm in plant genetics.

Scientists, farmers and managers work together to avoid the decline of the little bustard, an endangered steppe bird      (via sciencedaily.com)     Original source 

The collaboration between scientists, farmers and managers is crucial to improve the protection of the little bustard, an endangered steppe-land bird in Spain due to human activity. The reduction of natural habitats, the increase in irrigation and the urbanization of the land have led to having less surface areas that guarantee the survival of this vulnerable species.
