Exploring the underground connections between trees      (via sciencedaily.com)     Original source 

Fungal networks interconnecting trees in a forest is a key factor that determines the nature of forests and their response to climate change. These networks have also been viewed as a means for trees to help their offspring and other tree-friends, according to the increasingly popular 'mother-tree hypothesis'. An international group of researchers re-examined the evidence for and against this hypothesis in a new study.

Viruses could reshuffle the carbon cycle in a warming world      (via sciencedaily.com)     Original source 

The roles microbes play in ecosystems are changing with global warming. Microbes are also affected by infection by viruses, but scientists know relatively little about how these viral infections could change how microbes react to warming. In this study, scientists describe different ways that increasing temperatures could affect viruses and their microbial hosts. Their preliminary models show that viruses could alter carbon balance, causing some ecosystems to switch from net carbon sources to net carbon sinks.

Archaea in a warming climate become less diverse, more predictable      (via sciencedaily.com)     Original source 

Using a long-term multifactor experimental field site researchers showed that experimental warming of a tallgrass prairie ecosystem significantly altered the community structure of soil archaea and reduced their taxonomic and phylogenetic diversity.

Vanishing glaciers threaten alpine biodiversity      (via sciencedaily.com)     Original source 

With glaciers melting at unprecedented rates due to climate change, invertebrates that live in the cold meltwater rivers of the European Alps will face widespread habitat loss, warn researchers. Many of the species are likely to become restricted to cold habitats that will only persist higher in the mountains, and these areas are also likely to see pressures from the skiing and tourism industries or from the development of hydroelectric plants.

Indo-Pacific corals more resilient to climate change than Atlantic corals      (via sciencedaily.com)     Original source 

In the face of global warming and other environmental changes, corals in the Atlantic Ocean have declined precipitously in recent years, while corals in the Pacific and Indian Oceans are faring better. By describing several species of symbiotic algae that these corals need to grow, an international team has found that these mutualistic relationships from the Indo-Pacific may be more flexible and ultimately resilient to higher ocean temperatures than those in the Atlantic.

Fossil find in California shakes up the natural history of cycad plants      (via sciencedaily.com)     Original source 

According to researchers, a new analysis of an 80-million-year-old permineralized pollen cone found in the Campanian Holz Shale formation located in Silverado Canyon, California, offers a more accurate cycad natural history -- one where the plants diversified during the Cretaceous.

New research redefines mammalian tree of life      (via sciencedaily.com)     Original source 

Scientists from around the globe are using the largest mammalian genomic dataset in history to determine the evolutionary history of the human genome in the context of mammalian evolutionary history. Their ultimate goal is to better identify the genetic basis for traits and diseases in people and other species.

Early-nesting ducks at increased risk due to changes in climate, land use      (via sciencedaily.com)     Original source 

Each year approximately 10 million waterfowl fly north to their breeding grounds in the Prairie Pothole Region of North America, but the landscape that greets them has changed. Weather patterns and agricultural practices have significantly transformed the pothole-dotted native grasslands that waterfowl have used for thousands of years.

Elephant ecosystems in decline      (via sciencedaily.com)     Original source 

Global space for Asian elephant habitats has been in rapid decline since the 1700s, a new report reveals. More than 3 million square kilometers of the Asian elephant's historic habitat range has been lost in just three centuries and may underlie present-day conflicts between elephants and people.

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.

How the Amazon rainforest is likely to cope with the effect of future drought      (via sciencedaily.com)     Original source 

A major collaboration involving 80 scientists from Europe and South America has identified the regions of the Amazon rainforest where trees are most likely to face the greatest risk from drier conditions brought about by climate change. Based on the analysis, the scientists predict trees in the western and southern Amazon face the greatest risk of dying. They also warn that previous scientific investigations may have underestimated the impact of drought on the rainforest because those studies focused on the central-eastern part of the forest, which is the least vulnerable to drought.

A healthy but depleted herd: Predators decrease prey disease levels but also population size      (via sciencedaily.com)     Original source 

Nature documentaries will tell you that lions, cheetahs, wolves and other top predators target the weakest or slowest animals and that this culling benefits prey herds, whether it's antelope in Africa or elk in Wyoming. This idea has been widely accepted by biologists for many years and was formalized in 2003 as the healthy herds hypothesis. It proposes that predators can help prey populations by picking off the sick and injured and leaving healthy, strong animals to reproduce.

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.
