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.

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.'

An improved global understanding of river temperature could provide an important barometer for climate change and other human activities.

The world's forests are losing their ability to absorb carbon due to increasingly 'unstable' conditions caused by humans, a landmark study has found.

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.

When the Covid-19 pandemic hit in 2020 with associated travel restrictions, a research group shifted their overseas research projects to instead study the seagrass meadow ecosystem in Waquoit Bay, USA. It's a shallow, micro-tidal estuary on the south side of Cape Cod in Massachusetts.

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.

Scientists set out to address one of the biggest uncertainties about how carbon-rich permafrost will respond to gradual sinking of the land surface as temperatures rise. Using a high-performance computer simulation, the research team found that soil subsidence is unlikely to cause rampant thawing in the future.

Researcher see the interconnections between the systems in nature and how each component impacts the others. In Connecticut, rich in forests and farmland, experts see the potential that could position the state at the forefront of a climate-smart agriculture (CSA) approach using an emerging sustainable practice called biochar.

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.

Not all Chinook salmon are created equal, and this has a major impact on the energetics for southern resident killer whales. A recent study quantified the lipid content in Fraser River Chinook salmon -- the southern resident's preferred meal -- and found that spring-run Chinook salmon, the earliest to arrive to the Salish Sea are lipid-rich and energy dense; a critical factor for the killer whales who prey on them. Fraser River Chinook salmon that come later in the season have lower energy density.

Researchers have identified 26 global warming accelerators known as amplifying feedback loops that the researchers say aren't being properly included in climate models. They note that the findings add urgency to the need to respond to the climate crisis and provide a roadmap for policymakers aiming to avert the most severe consequences of a warming planet.

Researchers may have found the key to a truly efficient and inexpensive mechanism for removing carbon dioxide from seawater. The method could be far more efficient than existing systems for removing the greenhouse gas from the air.

Researchers propose a new approach to making qubits, the basic units in quantum computing, and controlling them to read and write data. The method is based on measuring and controlling the spins of atomic nuclei, using beams of light from two lasers of slightly different colors.

In mountainous western North America, vegetation cover has moved upward at a rapid rate over the past several decades, according to a new study. Understanding such shifts in species distribution could provide insights on the velocity of climate change and aid conservation planning.
