One famous dog and a powerful new approach for understanding biology and evolutionary history      (via sciencedaily.com)     Original source 

Ever since scientists first read the complete genetic codes of creatures like fruit flies and humans more than two decades ago, the field of genomics has promised major leaps forward in understanding basic questions in biology. Two recent articles break new ground by showing how much valuable information can be found in genomes of a single species, such as endangered orcas, or even in the DNA of an individual. That individual is a sled dog named Balto, who has been immortalized in movies and a statue for helping to bring lifesaving diphtheria antitoxin to Nome, Alaska in an epic journey across the Alaskan wilderness in the winter of 1925. With just a snippet of the dog's preserved skin researchers have made great discoveries.

Information 'deleted' from the human genome may be what made us human      (via sciencedaily.com)     Original source 

What the human genome is lacking compared with the genomes of other primates might have been as crucial to the development of humankind as what has been added during our evolutionary history, according to a new study led by researchers at Yale and the Broad Institute of MIT and Harvard. The new findings, published April 28 in the journal Science, fill an important gap in what is known about historical changes to the human genome.

Ant mounds are more important for biodiversity than previously thought      (via sciencedaily.com)     Original source 

The ant mounds on the heath, in the forest and in your garden are oases for life. The heat and nutrients from ant mounds make them the perfect home for unique plant and animal species, according to new research.

Researchers explore techniques to successfully reintroduce captive birds into the wild      (via sciencedaily.com)     Original source 

Studies show that some species may require breeding in captivity within the next 200 years to avoid extinction. This reality places heavy importance on the reintroduction practices used to successfully transfer species from captivity to the wild. A new study looks at some of the most popular conservation techniques and identifies which have the highest likelihood of success for the reintroduction of bird species back into the wild.

Cheetahs need more space: Reintroduction in India must consider their spatial ecology      (via sciencedaily.com)     Original source 

In autumn 2022 and winter 2023, a total of 20 cheetahs from Namibia and South Africa were introduced to Kuno National Park in India to establish a free-ranging population -- for the first time since their extinction in India 70 years ago. Although the idea may be commendable, getting it right is not so easy. Scientists see shortcomings in the reintroduction plan: In southern Africa, cheetahs live in a stable socio-spatial system with widely spread territories and densities of less than one individual per 100 km².

The climate crisis and biodiversity crisis can't be approached as two separate things      (via sciencedaily.com)     Original source 

Anthropogenic climate change has, together with the intensive use and destruction of natural ecosystems through agriculture, fishing and industry, sparked an unprecedented loss of biodiversity that continues to worsen. In this regard, the climate crisis and biodiversity crisis are often viewed as two separate catastrophes. An international team of researchers calls for adopting a new perspective.

African penguins: Climate refugees from a distant past?      (via sciencedaily.com)     Original source 

Imagine the view from the western coastline of southern Africa during the Last Glacial Maximum (LGM) over twenty thousand years ago: in the distance you would see at least fifteen large islands -- the largest 300 square kilometers in area -- swarming with hundreds of millions of marine birds and penguin colonies.

X-ray analysis sheds new light on prehistoric predator's last meal      (via sciencedaily.com)     Original source 

We now know more about the diet of a prehistoric creature that grew up to two and a half meters long and lived in Australian waters during the time of the dinosaurs, thanks to the power of x-rays. Researchers used micro-CT scans to peer inside the fossilized stomach remains of a small marine reptile -- a plesiosaur nicknamed 'Eric' after a song from the comedy group Monty Python -- to determine what the creature ate in the lead up to its death.

The diversity of present tree species is shaped by climate change in the last 21,000 years      (via sciencedaily.com)     Original source 

A new global survey of 1000 forest areas shows how climate change since the peak of the last ice age has had a major impact on the diversity and distribution of tree species we see today. The results can help us predict how ecosystems will react to future changes, thus having an impact on conservation management around the globe.

Learning about what happens to ecology, evolution, and biodiversity in times of mass extinction      (via sciencedaily.com)     Original source 

Studying mass extinction events from the past can build our understanding of how ecosystems and the communities of organisms within them respond. Researchers are looking to the Late Devonian mass extinction which happened around 370 million years ago to better understand how communities of organisms respond in times of great upheaval.

Anthropologists have long thought that our ape ancestors evolved an upright torso in order to pick fruit in forests, but new research from the University of Michigan suggests a life in open woodlands and a diet that included leaves drove apes' upright stature.

British flower study reveals surprise about plants' sex life      (via sciencedaily.com)     Original source 

A study of Britain's native flowering plants has led to new insights into the mysterious process that allows wild plants to breed across species -- one of plants' most powerful evolutionary forces.  When wild flowering plants are sizing up others they may often end up in a marriage between close relatives rather than neighbors, a new study has revealed.
