A recent study finds that the largest trees in Peruvian Amazon store disproportionately large amounts of carbon, making it difficult to achieve net-zero emissions. Protecting these trees can help conserve biodiversity and forest microclimates against future climate change.
Global net primary production increased significantly between 2003 and 2021 due to land's photosynthetic increase, but declined in marine algae. The study highlights the importance of terrestrial ecosystems in offsetting ocean declines.
A new study using NASA's PACE satellite data established a novel method to determine global plant productivity. The technique relies on the light plants reflect, allowing for accurate capture of short-term changes. This approach has significant implications for understanding carbon sequestration, climate change, and ecosystem monitoring.
Researchers discovered bacteria can produce methane in oxygen-saturated surface waters, using methylphosphonate as a phosphorus source. This process has significant effects on atmospheric greenhouse gases and the carbon cycle of nutrient-poor ocean regions.
A new study reveals that the decline of Arctic sea ice is altering zooplankton behavior, leading to more frequent food shortages and potential negative effects on larger species. The changing light conditions are affecting the daily vertical migration of zooplankton in the Arctic.
A research team at Ritsumeikan University has identified the elusive ApiT gene in celery, crucial for apiin synthesis. The discovery may pave the way for efficient biosynthesis of apiin, a compound with potential health benefits and medicinal uses.
A study by UPV/EHU's Ekopol and Life Cycle Thinking groups found that an alternative community lifestyle can reduce energy consumption due to the significance of energy used in goods and services. The energy footprint per inhabitant of Errekaleor neighbourhood is 24% lower than that of ACBC.
Researchers found that urban vegetation's carbon capture ability has increased, offsetting negative impacts of urbanization. The study suggests that urban management and climate factors play a crucial role in maintaining or increasing GPP in urban areas.
A new study sheds light on the leaf traits and productivity of C4 bioenergy crops, revealing distinct niches in the leaf economics spectrum. The research found that miscanthus and sorghum, two C4 plant species, have higher photosynthetic rates and nitrogen use efficiency than common C3 plants.
A new study reveals that global warming will shift the timing of ocean plankton blooms, impacting the marine food web and potentially disrupting the delicate coupling between phytoplankton growth and zooplankton abundance. This change could have severe consequences for high-latitude regions.
A new study by Bigelow Laboratory for Ocean Sciences reveals that microbial life in the ocean is adapting to warmer conditions, maintaining vital processes despite climate change. The research found that carbon export was maintained as phytoplankton populations declined due to other small organisms taking up the slack.
Phytoplankton are critical to life in ocean waters, and their seasonal availability is shifting due to climate change. Researchers found that carbon produced by phytoplankton is sinking into the deep ocean, impacting global nutrient availability and ocean ecosystems.
Researchers used mathematical models to reconstruct evolutionary history of photosymbiosis in Scleractinia, identifying groups where association is stable and others that may be more flexible. The study found that certain lineages are more likely to retain the reef-building trait in a changing climate.
Researchers Alli Cramer and Stephen Katz identified two key variables: gross primary production and substrate mobility, which sort biomes by their energy flow and ocean floor movement. This new classification system sheds light on the diversity of marine environments and highlights areas where human actions may impact ecosystem function.
The Sahel region is experiencing a shrinking margin between supply and demand for primary production, driven by population growth and increasing consumption. The study found that the rate of increase in food needs was 2.2% per year, while crop production remained largely unchanged over the past decade.
A long-term study of box jellyfish abundance reveals a strong positive relationship with the North Pacific Gyre Oscillation index, primary production, and small zooplankton abundance. The study confirms predictable timing based on the moon cycle but shows no net increase or decrease in numbers over 14 years.
