Research by Göttingen University and collaborators reveals that tree islands within oil palm monocultures can naturally regenerate native tree diversity through ecological restoration. Larger island areas are particularly essential for endemic tree species struggling to find habitats.
New research reveals nitrogen pollution as primary driver of westward shifts in European forest plant distribution. High levels of atmospheric nitrogen deposition allow rapid spread of nitrogen-tolerant species, often at expense of specialized plant species.
Scientists found that ferns and flowering plants evolved similar nectaries independently to attract ant bodyguards. This suggests a shared evolutionary framework for these plant lineages.
A study by MLU found that ecosystems with diverse plant mixes can regulate up to 5% of regional climate, while plant traits like leaf thickness affect climate. The research highlights the complex relationship between plants and climate, emphasizing the need for biodiversity in nature conservation.
A new study reveals that wildebeest populations which no longer migrate are less genetically healthy and more prone to decline. The loss of migration routes due to fencing and roads leads to lower genetic diversity, increased inbreeding, and reduced fertility.
A new rapid test has been developed to identify hantavirus in South Korea, paving the way for early outbreak control. The Flongle sequencing-based diagnostic is cost-efficient and can detect HTNV genomes within 3 hours.
A new study published in Science found that eradicating non-native animals to protect plant species can be a flawed practice, costing millions and slaughtering healthy wild animals. The research compared the effects of native and introduced large herbivores on plant communities, finding no significant differences.
Researchers used statistical methods to investigate the extent of climate support for the Eurasian forest-steppe zone's delineation. The study found that macroclimate explains a significant portion of the zone's distribution, with some regions showing strong agreement and others requiring further refinement.
A research team led by the University of Göttingen investigated the flora of Tenerife and found that island plant-life exhibits a remarkable diversity of forms. However, the plants differ little from mainland plants in functional terms, with slow-growing, woody shrubs dominating the island's flora.
Researchers have developed a battery-free GPS tracker that harnesses kinetic energy from an animal's movements, allowing for longer-term tracking. The 'KineFox' device has been tested on several species, including horses and dogs, and shows promise for monitoring endangered species.
A study analyzing over 300,000 European vegetation plots found that global climate gradients have relatively weak correlations with local plant community characteristics. The effects of climate change on plant species depend heavily on local factors such as soil conditions and microclimate.
