A long-term study found that habitat fragmentation has a far-reaching impact on rainforests, increasing local extinction rates and altering species richness. To maintain diversity and dynamics, Amazonian nature reserves will need to be very large to withstand human disturbances.
A study suggests that the global extinction crisis is more severe than previously thought, with over 50% of declining mammal species losing historic ranges. Population extinctions are concentrated in densely populated areas, such as Southeast Asia and Eastern states.
Researchers from Wageningen University predict the species diversity of large herbivores in nature reserves by analyzing soil fertility and rainfall data. The study finds that areas with fertile soil and average rainfall are ideal for high species diversity, contrary to expectations.
A new study maps prime regions for plant-eating mammals, revealing areas with high conservation value. The researchers predict that less than 1.2% of the earth's surface will support uniquely diverse grazing ecosystems by 2025.
Biodiversity hotspots, home to 55% of world's primates and 22% of carnivores, are facing extinction, threatening 343 million years of evolutionary history. Preserving these ecosystems is crucial to maintaining genetic diversity and the survival of species.
Researchers have discovered an experiment conducted by George Sinclair, head gardener to the Duke of Bedford, in a garden at Woburn Abbey in South East England. The study investigated the relationship between biodiversity and ecosystem functioning, which is currently a hot topic in ecology. The findings push back the link between commu...
The discovery of the Jaragua Sphaero, a lizard measuring about three quarters of an inch from snout to tail, highlights the Caribbean's unique species diversity. Rapid population growth, agricultural practices, and lack of access to data contribute to the region's biodiversity loss.
The Global Litter Invertebrate Decomposition Experiment (GLIDE) aims to advance understanding of soil and litter fauna's distribution, diversity, and importance in ecosystem processes. The study will provide unprecedented data on the animals involved in litter decomposition across different biomes and latitudes.
Preliminary findings from a deep-sea expedition have uncovered a vast array of new species in the Atlantic Ocean's abyssal plains. The discovery, part of the DIVA project, confirms the diversity of deep-sea life and reveals significant differences in sediment structure and fauna composition across different sites.
Researcher David Tilman's study found that mixing multiple plant species leads to higher productivity, as each species brings unique traits for resource utilization. This principle can benefit various ecosystems, including forests and fisheries, by promoting a more diverse range of organisms.
A new UC Berkeley study reveals that diverse ecosystems are not immune to invasion by alien species. In a series of experiments, researchers found that high diversity actually increases the likelihood of invader establishment in larger ecosystems.
Research reveals highest species diversity of planktonic foraminifera in middle latitudes, contrary to traditional model. Sea-surface temperature can accurately estimate zooplankton diversity.
A Colorado State University project, funded by a $1.8 million grant, aims to catalogue and analyze below-ground organisms and their interactions with surface ecosystems. The study seeks to understand how human activities above ground influence biodiversity below ground and its consequences.
Research reveals that bison grazing can increase plant species diversity in stressed grasslands, countering the effects of fire and fertilizer. By reestablishing grazing, scientists find that biodiversity can be retained in ecosystems impacted by human activities.
Paleontologist Dr. Roger Cuffey compares the diversity of dinosaurs and proboscideans, finding a similar pattern of decline over 5 million years. The study suggests that both groups were affected by complex factors, including food supply and habitats, leading to their extinction.
