Published The world's first horse riders


Researchers have discovered evidence of horse riding by studying the remains of human skeletons found in burial mounds called kurgans, which were between 4500-5000 years old. The earthen burial mounds belonged to the Yamnaya culture. The Yamnayans had migrated from the Pontic-Caspian steppes to find greener pastures in today's countries of Romania and Bulgaria up to Hungary and Serbia.
Published Genomic study of indigenous Africans paints complex picture of human origins and local adaptation


An international team of researchers analyzed the genomes of 180 indigenous Africans from a dozen ethnically, culturally, linguistically, and geographically diverse populations. The results shed light on the origin of modern humans, historical migrations, linguistic evolution, and local adaptation, and lay the groundwork for more people to benefit from precision medicine.
Published Bronze Age well contents reveal the history of animal resources in Mycenae, Greece



A large Bronze Age debris deposit in Mycenae, Greece provides important data for understanding the history of animal resources at the site, according to a new study.
Published Ice Age survivors


Large-scale genomic analysis documents the migrations of Ice Age hunter-gatherers over a period of 30,000 years -- they took shelter in Western Europe but died out on the Italian peninsula.
Published Deforestation in the tropics linked to a reduction in rainfall


Deforestation is resulting in reduced rainfall across large parts of the tropics, according to new research. People living in tropical forest communities have often complained that the climate gets hotter and drier once trees are cleared but until now, scientists have not been able to identify a clear link between the loss of tree cover and a decline in rainfall.
Published Oldest human genome from southern Spain


A new study reports on genomic data from a 23,000-year-old individual who lived in what was probably the warmest place of Europe at the peak of the last Ice Age. The oldest human genome recovered from the southern tip of Spain adds an important piece of the puzzle to the genetic history of Europe.
Published Steel was being used in Europe 2900 years ago


Researchers have discovered what they believe is the earliest use of steel in Europe -- on Iberian stone pillars from the Final Bronze Age.
Published Flower power: The role of ants in forest regeneration


Ants play a key role in forest regeneration, according to a new article.
Published Australia's rarest bird of prey disappearing at alarming rate


Australia's rarest bird of prey -- the red goshawk -- is facing extinction, with Cape York Peninsula now the only place in Queensland known to support breeding populations.
Published New study reveals biodiversity loss drove ecological collapse after the 'Great Dying'


By exploring the stability and collapse of marine ecosystems during the Permian-Triassic mass extinction, researchers gain insights into modern biodiversity crisis.
Published Urban ponds require attention to ensure biodiversity


New research suggests aquatic plants can be utilized as a tool to enhance the co-existence between aquatic invertebrates and their fish predators in urban ponds.
Published Clever orchard design for more nuts


To reduce biodiversity loss in agricultural landscapes, more sustainable and environmentally friendly agricultural practices are needed. A research team has investigated how ecosystem services such as pollination could be improved in macadamia plantations. The scientists showed that a certain design of plantations -- for instance, how the rows of trees are arranged, the varieties, and the integration of semi-natural habitats in and around the plantations -- can increase the pollination performance of bees.
Published A fifth of California's Sierra Nevada conifer forests are stranded in habitats that have grown too warm for them


Researchers created maps showing where warmer weather has left trees in conditions that don't suit them, making them more prone to being replaced by other species. The findings could help inform long-term wildfire and ecosystem management in these 'zombie forests.'
Published Rising river temperatures hold important clues about climate and other human impacts


An improved global understanding of river temperature could provide an important barometer for climate change and other human activities.
Published Climate 'spiral' threatens land carbon stores


The world's forests are losing their ability to absorb carbon due to increasingly 'unstable' conditions caused by humans, a landmark study has found.
Published New research reveals 12 ways aquaculture can benefit the environment


Aquaculture, or the farming of aquatic plants and animals, contributes to biodiversity and habitat loss in freshwater and marine ecosystems globally, but when used wisely, it can also be part of the solution, new research shows.
Published Researcher discovers threshold that triggers drought response in forests


Missouri is home to an array of natural resources, with forests among the state's most valuable ecosystems. As warmer temperatures fueled by climate change affect ecosystems globally, forests are under stress to adapt to these changes and ensure their survival in a warmer world. Researchers now introduce the 'ecosystem wilting point' concept, which explains how whole forests respond to drought.
Published Detecting the impact of drought on plants with user-friendly and inexpensive techniques


Climate change is aggravating the impact of droughts -- one of the factors that only affect plant physiology -- on all plant ecosystems worldwide. Although new tools have been developed to detect and assess drought stress in plants -- transcriptomic or metabolomic technologies, etc. -- they are still difficult to apply in natural ecosystems, especially in remote areas and developing countries.
Published Gene variations for immune and metabolic conditions have persisted in humans for more than 700,000 years


A new study explores 'balancing selection' by analyzing thousands of modern human genomes alongside ancient hominin groups, such as Neanderthal and Denisovan genomes. The research has 'implications for understanding human diversity, the origin of diseases, and biological trade-offs that may have shaped our evolution,' says evolutionary biologists.
Published Amazon mammals threatened by climate change


Most land-based mammals in the Brazilian Amazon are threatened by climate change and the savannization of the region.
