A study found that bats, not bird numbers, contribute to pest control in macadamia nut production. Higher bat activity reduces insect damage and increases yields, with natural habitats playing a crucial role in supporting beneficial organisms.
Researchers found that a fungus's metabolic breadth, or range of nutrients it can use, links its ability to kill insects, partner with plants, and thrive in different ecological roles. Strains capable of using a wider range of nutrients were faster and deadlier at killing insects and more effective at colonizing plant roots.
A newly discovered Australian ballista spider uses a silk-powered snare to target and capture the highly aggressive green tree ant Oecophylla smaragdina, launching its prey into the air with incredible power and speed. The snare is triggered by the prey's reaction and stores elastic energy in the silk to release it rapidly.
A study by the Max Planck Institute for Chemical Ecology found that an introduced bacterium can replace an ancient insect symbiont within a few generations. The beetles exhibited reduced reproduction rates, lower life expectancy, and altered immune systems after infection with the new bacterium.
A new comprehensive study reveals that modern afforestation in Europe is contrary to the continent's long-term ecological trajectory. The study suggests that dense forests are a recent phenomenon and that current reforestation practices are on the wrong track, harming biodiversity.
The study confirms that ancient lichens played a key role in forming the first soils and structuring terrestrial ecosystems. Researchers identified the presence of chitin, nitrogen compounds, and calcium microparticles compatible with modern lichen minerals.
A new study reveals that resilient nematodes can persist in the Atacama Desert's hostile soil, with population diversity correlating to water profile and temperature fluctuations. The findings suggest that biodiversity in arid regions may be higher than previously assumed, but also warn of ecosystem damage.
A new study by Dr. Tiago de Melo Cartaxo from the University of Exeter reveals that UNESCO Biosphere Reserves' less prescriptive regulations promote harmonious coexistence between people and nature. The use of soft law instruments supports local responses and fosters community collaboration in environmental management.
Researchers at OIST found that only cyanobacteria Trichormus azollae are true symbionts of Azolla ferns, with their genomes showing extreme decay and loss of genes. The study sheds light on the genomic impacts of symbiosis and its potential applications in food security.
A study published in the Royal Society's Proceedings B found that closely related bat and bird species share the same habitat due to their shared evolutionary history. This challenges previous ideas about competition driving species apart, suggesting that animals with similar needs tend to group together in suitable habitats.
A new study reveals that climate change is rapidly becoming a third major threat to Earth's wild animals, alongside habitat alteration and overexploitation. The research found that 5.1% of assessed animal species are threatened by climate change, with six classes having at least 25% of species at risk.
Researchers develop novel method to combat malaria vector Anopheles stephensi using satellite imagery, machine learning and mobile apps. The strategy targets water sources during dry season to eradicate larvae.
A new study reveals how proactive salmon conservation in the North Pacific can protect biodiversity and advance global conservation goals. The stronghold strategy aims to proactively protect iconic salmon systems that sustain healthy watersheds, safeguarding food security and mitigating climate change.
A new paper reveals that information exchange between species influences behavior, interactions, and ecosystem dynamics. The authors identify three types of information links within ecosystems: trophic, pure, and environmental information links.
Researchers used cutting-edge molecular biology tools and GPS tracking data to determine the dietary habits of different animal species in Yellowstone. They found that feeding behaviors depend on body size, with smaller species diversifying their diets in summer and larger animals competing for resources in winter.
A recent study by Oregon State University reveals that a surge in purple sea urchins is devastating kelp forests, reducing zooplankton populations and impacting the primary prey of gray whales. This cascading effect affects the top predator, causing them to spend less time foraging in the affected area.
Professor Shuqing Xu's research aims to investigate the connections between species interactions and evolutionary responses to climate change. He will create aquatic pond systems with hundreds of species to study how organisms respond to temperature increases, with potential findings on coevolution and ecosystem functions.
A recent study has shown that the mutual symbiosis between bacteria and fungi can be fragile, as a specific protein maintains the balance. When this protein is absent, the bacteria are trapped within fungal hyphae and die.
Current measures to protect grasslands in the Qinghai-Tibetan Plateau are damaging the ecosystem and should be stopped. Small burrowing mammals, like the plateau pika and zokor, play crucial ecological roles in maintaining ecosystem health and biodiversity.
A study in Washington state found that when wolves and cougars moved into an area, coyotes and bobcats shifted their movements into regions with higher levels of human activity. However, it was humans who finished off the smaller predators, with over half of the coyotes killed by people during the study period.
A global survey of 1000 forest areas reveals how past climate change has impacted tree species diversity and distribution. The study found that temperature changes since the last ice age have had a significant impact on today's biodiversity.
Research found that North American wildflower timing is more sensitive to warmer temperatures than surrounding tree growth, threatening the flower's ability to grow. In contrast, European and Asian forests show a synchronized shift in tree and wildflower phenology, potentially leading to increased light for wildflowers.
A new study by Rice University biologist Tom Miller explores the role of fungi in determining the range limits of plants in Texas. The research reveals that fungal partnerships improve drought tolerance and could potentially extend the range of grasses in response to climate change.
A new study found that North American mammal communities have become more than twice as homogenous as they were 10,000 years ago, primarily due to early human hunting and farming activities. The accelerated homogenization is likely linked to the spate of large-mammal extinctions, which increased similarity among remaining species.
A study has discovered that humans are disrupting a fundamental pattern in ecosystems, which dates back at least 66 million years. The U-shaped relationship between diet and size in modern land mammals has been found to span across multiple vertebrate groups, including birds, reptiles, and fish.
Human activity on Hainan Island is causing changes in the body shapes and diets of tropical birds, resulting in biotic homogenisation. Despite efforts to protect biodiversity, the island's unique ecosystem is being affected by large-scale economic and land-use changes.
Researchers found that livestock grazing had no negative impact on snow leopard distribution or density, and the species can coexist due to their separate ecological niches. The study suggests a more nuanced approach to conservation and land use, prioritizing the preservation of rocky mosaics.
A University of Ottawa review provides the first field-wide summary of how pesticide exposure affects social bee gut microbiotas. The study found that pesticides disturb microbial communities, leading to a loss of benefits and potential decline in bee health and performance.
Researchers found animal-dispersed plant species' ability to adapt to climate change reduced by 60% due to bird and mammal losses. Global seed dispersal mapping revealed severe declines in temperate regions, with tropical areas at high risk if endangered species go extinct.
