Natural environments favor 'good' bacteria

A new study reveals that restoring degraded landscapes to biodiverse ecosystems favors more stable and specialist bacteria over opportunistic ones. This shift in bacterial composition has potential immune-boosting effects, suggesting a connection between healthy ecosystems and human health.

Size is everything

A new method has been developed to predict the vulnerability of ecosystems, focusing on predators' body mass and prey characteristics. The approach enables researchers to determine habitat structure and stability without comprehensive data on all organisms.

The sicker the better

Research found that nematode-infected horned passalus beetles process wood 15% faster than uninfected ones, leading to increased decomposition rates. The parasites are beneficial to the forest ecosystem, enabling the beetles to provide a more effective service

The Serengeti squeeze: Human activities at edges of protected areas undermine these ecosystems

A new study in the Serengeti-Mara ecosystem highlights how human activity near protected areas affects wildlife and ecosystem function. The results show that human pressure has caused wildlife to migrate to the core of the park, resulting in changes to fire regimes, grazing patterns, and increased vulnerability to droughts.

Landscapes of fear, and the large carnivores they feature, important in African ecosystems

A new study on Mozambique's Gorongosa National Park shows that the loss of top carnivores can have far-reaching consequences for prey and plant populations, turning 'landscapes of fear' into 'landscapes of fearlessness'. However, carnivore restoration in these areas could help reverse any ill effects of human activity.

Biodiversity crisis: Technological advances in agriculture are not a sufficient response

A study by the German Centre for Integrative Biodiversity Research (iDiv) finds that technological advances in agriculture are not sufficient to address biodiversity loss, which is driven by population and economic growth. The research highlights the need for policies addressing these factors to mitigate biodiversity decline.

New study finds ecosystem changes following loss of great white sharks

A new study has documented the unexpected consequences of great white shark decline on an ocean ecosystem. Sevengill sharks, a top predator with unique characteristics, have emerged as a result of great whites' disappearance. The researchers observed sevengill shark sightings increasing in number after great whites vanished from surveys.

New study looks at costs and benefits of paying for ecosystem services

A recent study by Smithsonian Tropical Research Institute scientists evaluated the economic viability of PES programs in the PCW, finding that reforestation efforts have a significant impact on ship transits and dry-season water flow. The researchers also identified market clearing equilibriums for such programs, highlighting their pot...

More diversity than before

Researchers found that hybridization during eutrophication led to an expansion in biodiversity of the European whitefish species once the ecosystem recovered. This rapid niche expansion was made possible by genetic variation, demonstrating functional variation can quickly recover after ecosystem restoration.

New study explores ecosystem stability

A new study examined ancient ecosystems to understand what drives stability, finding that functional groupings are more important than the sheer number of species present. The team also found that ancient ecosystems were more stable than simulated systems, suggesting a strong imprint on history of how ecosystems are built over time.

Something to chew on

A team of scientists found that herbivory has a complex relationship with plant diversity, but is crucial for maintaining biodiversity when dominant species are present. In some grasslands, herbivores help regulate the growth of fast-growing plants and promote smaller, slower-growing species.

How we can get more out of our forests

A study by an international research group found that diverse and old forests are best able to perform multiple ecosystem services, including regulating climate and storing carbon. Foresters should focus on specific forest attributes to promote desired services, as no single 'perfect forest' exists.

Why do we love bees but hate wasps?

Researchers found that people's dislike of wasps is largely due to a lack of knowledge about their role in regulating pest populations and disease-carrying insects. The study suggests that changing public attitudes towards wasps could help protect the ecosystem's biodiversity.

The world needs death and decomposition

A new study by Michigan State University establishes a baseline of organisms that play key roles in carrion decomposition, promoting the importance of death in ecosystems. The research also highlights the complex interactions between decomposer communities and their impact on nutrient cycling and ecosystem processes.
