Published The reasons why insect numbers are decreasing



Researchers are investigating the causes and consequences of the worldwide insect decline as well as considering potential countermeasures.
Published One famous dog and a powerful new approach for understanding biology and evolutionary history



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.
Published Ant mounds are more important for biodiversity than previously thought



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.
Published Researchers explore techniques to successfully reintroduce captive birds into the wild



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.
Published Twilight zone at risk from climate change



Life in the ocean's 'twilight zone' could decline dramatically due to climate change, new research suggests.
Published Prehistoric scat reveals 'Waves' of extinction in Colombia



Fungal spores found in dung have revealed that large animals went extinct in two 'waves' in the Colombian Andes.
Published New programmable smart fabric responds to temperature and electricity



A new smart material is activated by both heat and electricity, making it the first ever to respond to two different stimuli.
Published Neuroptera: Greater insect diversity in the Cretaceous period



An LMU team has studied the biodiversity of larvae from the insect order neuroptera over the past 100 million years.
Published Cheetahs need more space: Reintroduction in India must consider their spatial ecology



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.
Published The climate crisis and biodiversity crisis can't be approached as two separate things



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.
Published African penguins: Climate refugees from a distant past?



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.
Published Surface steers signals for next-gen networks



5G signals known as millimeter-wave carry enormous amounts of information but are very easy to block. A new device helps these signals get around obstacles posed by walls, furniture and people.
Published The diversity of present tree species is shaped by climate change in the last 21,000 years



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.
Published Swimming secrets of prehistoric reptiles unlocked by new study



The diverse swimming techniques of the ancient reptiles that ruled the Mesozoic seas have been revealed.
Published Learning about what happens to ecology, evolution, and biodiversity in times of mass extinction



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.
Published British flower study reveals surprise about plants' sex life



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.
Published Scientists advocate for integration of biogeography and behavioral ecology to rapidly respond to biodiversity loss



An interdisciplinary team of researchers is advocating for convergent research that integrates the fields of biogeography and behavioral ecology to more rapidly respond to challenges associated with climate change and biodiversity loss.
Published Scientists show how we can anticipate rather than react to extinction in mammals



Most conservation efforts are reactive. Typically, a species must reach threatened status before action is taken to prevent extinction, such as establishing protected areas. A new study shows that we can use existing conservation data to predict which currently unthreatened species could become threatened and take proactive action to prevent their decline before it is too late.
Published In Florida study, nonnative leaf-litter ants are replacing native ants



A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants -- even in protected natural areas of the state, researchers report.
Published Technology advance paves way to more realistic 3D holograms for virtual reality and more



Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. They now describe their new approach, called three-dimensional scattering-assisted dynamic holography (3D-SDH). They show that it can achieve a depth resolution more than three orders of magnitude greater than state-of-the-art methods for multiplane holographic projection.
