For almost 20 years, researchers at the Santa Barbara Coastal Long-Term Ecological Research (SBC LTER) site have conducted detailed censuses of the majestic kelp forests off Santa Barbara. By counting fish species and placing them in the context of their environmental conditions, UCSB coastal marine ecologist Robert Miller and his colleagues can look at the effects of human activity and natural drivers on kelp and its ability to maintain the kelp forest communities.
In the fruit fly Drosophila, a hormone helps to balance rest and activity. This is shown by a new study of a research team led by the University of Würzburg. Might humans have a hormone with comparable function?
With wildfires spreading across the parched Western U.S., severe floods in Europe and in the coming decade a potential surge in coastal flooding, 2021 could be a pivotal year in how governments, societies and families view the threat of climate change.
Minuscule tunnels through the cell membrane help cells to perceive and respond to mechanical forces, such as pressure or touch. A new study in the journal Science is among the first to directly investigate what one type of these mechanosensitive ion channels is doing in the tip-growing cells in moss and pollen tubes of flowering plants, and how.
Wine growers in the Champagne region, home to the world's most exclusive bubbly, on Thursday scrapped a century-old rule governing the distance between vines, sparking fierce resistance from traditionalists.
In just the last 60 years alone, deliberately or accidentally introduced invasive species have cost the Australian economy AUD$389.59 billion, a new analysis has revealed, with that number likely to rise unless better investments, reporting and coordinated interventions are introduced.
The growth of cities with their streetlights and illuminated buildings has led to brighter nights. This has consequences for animals: the artificial light illuminates them directly, but also lights up the sky, making the stars invisible. Yet many animals rely on the stars as their compass for orientation.
Bacteria are increasingly resistant, especially to antibiotics, which is a major global health problem. An example, related to the pandemic? Covid weakens hospitalized people so much that we are now witnessing an upsurge in bacterial infections (resistant bacteria engulf the breach caused by the virus and further weaken patients). Research in this area is therefore essential.
Together with an international team, Senckenberg scientists have investigated the costs incurred by invasive species in Europe and Germany. In their studies, published today in the scientific journal NeoBiota, they show that in European countries, non-native species caused damage in excess of 116.61 billion Euros in the period from 1960 to 2020. In Germany, the figure for the same period is an estimated 8.21 billion Euros. According to the researchers, the expenditures increased tenfold in each decade—and the actual costs are probably many times higher.
Floral initiation must be strictly regulated to achieve reproductive success. ETHYLENE RESPONSE FACTOR1 (ERF1) functions as an important integrator of several phytohormone signals to regulate both development and stress responses. However, the underlying mechanism for its role in flowering-time regulation remained unclear.
Researchers at the University of Stirling have developed a new tool that fish farmers can use to improve the welfare of lumpfish—a species crucial to tackling the problem of sea lice in salmon.
New research on the euthanasia of stranded marine mammals has highlighted the need for increased reporting and improved data collection on the euthanasia of sick, injured or debilitated stranded marine mammals globally.
Humans have harnessed the power of microbes for centuries, for example using yeast to make bread, beer, yogurt and wine via fermentation. These living organisms are useful to us because they perform chemical reactions as part of their everyday life.
After the corn harvest last fall, Illinois farmer Paul Jeschke planted a fraction of his fields with cereal rye: 60 acres of the 4,500 he farms with his wife, nephew and brother-in-law, tucked behind a pasture, out of neighbors' sight. That way they could experiment with cover crops, Jeschke explained, and no one could view potential failures.
Rats choose carefully who they spend time with, according to a new study published today. Published by researchers from the Universities of Portsmouth and Lincoln, the study found that male rats have preferred partners in their groups and they decide who to avoid, too.
Scientists have discovered that the protein ubiquitin plays an important role in the regulation of the aging process. Ubiquitin was previously known to control processes such as signal transduction and metabolism. Prof. Dr. David Vilchez and his colleagues at the CECAD Cluster of Excellence for Aging Research at the University of Cologne performed a comprehensive quantitative analysis of ubiquitin signatures during aging in the model organism Caenorhabditis elegans, a nematode worm broadly used for aging research. This method—called ubiquitin proteomics—measures all changes in ubiquitination of proteins in the cell.
Nitrogen is one of the major building blocks of life. It makes up 80 percent of Earth's atmosphere and it is described as one of the most important growth-limiting nutrients for both land and marine plants. This is because the most abundant form of nitrogen—dinitrogen, or N2—is particularly stable and resistant to chemical reactions, meaning that it cannot be assimilated by most organisms. Given the important role nitrogen plays in all living matter, microbes that can 'fix' atmospheric N2 into more accessible forms for organisms are crucial components of Earth's ecosystems.
Primates who are more tolerant of each other use vocal communication more than their stricter counterparts, research from the University of York shows.
Converting vacant urban lots into greenspaces can reduce blight and improve neighborhoods, and new research shows that certain types of such post-industrial reclamation efforts offer the added bonus of benefiting bees.
According to the Save the Chimps sanctuary in Fort Pierce, Fla., history was made when non-human primates created NFTs (non-fungible tokens). As with all NFTs, these pieces are unique digital collectibles.
