A new study using satellite data found that dryland ecosystems are experiencing escalating instability, with 80% of global drylands showing increased variability. This boom-and-bust dynamic threatens rain-fed agriculture and ecology, with implications for livestock production and rangeland management.
The study found a clear hump-shaped elevational pattern with species richness peaking at approximately 600 m, supporting the mid-domain effect. Community structure was differentiated by body size and biomass, with lizards contributing most of the individuals but only 66% of total biomass.
Researchers challenge long-held assumptions about vegetation patterns in dryland ecosystems, finding that such patterns can actually indicate reduced ecosystem resilience. The new theoretical framework takes into account spatial constraints and environmental heterogeneities, revealing that ecosystem stability depends on specific enviro...
A new study found that some Arctic regions regain their 'greenness' within a decade of a sudden permafrost collapse, while others can take centuries or more to recover. The difference is directly related to each site's gross primary productivity, allowing scientists to predict how long it will take a specific site to recover after a pe...
A team of researchers has developed a novel method to track the Earth's greenness by calculating its centre of mass. They found that the 'green centre' oscillates between northernmost positions in mid-July and southernmost positions off the coast of Liberia in March, with a consistent northward shift across all seasons.
A recent study from Norwegian University of Science and Technology suggests that optimizing production in fertile areas while allowing less productive areas to lie fallow can cut greenhouse gas emissions. By doing so, food production can be maintained while reducing pressure on biodiversity by up to 20%.
A Canadian national study found that older adults living in greener neighborhoods were less likely to experience depression during the early months of the COVID-19 pandemic. Access to nearby green spaces acted as a mental health buffer, especially for those without a prior history of depression, lower-income Canadians, and individuals ...
Researchers identified three principal modes of interannual summer vegetation growth patterns in eastern Siberia, influenced by factors like soil moisture and sea surface temperature anomalies. The year-to-year increment method developed for climate prediction shows superior predictive capability.
A research team at the University of Turku developed a novel biomimetic fabrication technique to replicate bioinspired microstructures found in plant leaf skeletons. The resulting surfaces offer superior flexibility, breathability, and transparency, making them ideal for next-generation flexible electronics.
Researchers developed a numerical tool to quantify sunlight intensity and its influence on plant growth, enabling accurate predictions of sunlight patterns. The model can help farmers optimize greenhouse conditions and planting schedules, leading to improved crop yields.
A long-term study in the Spiti valley of the Himalayas found that livestock grazing leads to reduced spider populations and increased grasshoppers and disease carriers like ticks and mites. The researchers suggest rewilding native herbivores and improved surveillance to mitigate these changes.
A recent study published in Nature Sustainability analyzed global forest disturbance patterns from 2002 to 2014, identifying four main types of patches and mapping their distribution across different biomes. Human activities tend to leave similar patterns globally, with potential implications for forest resilience.
Indigenous women in the Amazon region of Brazil created varnished gourds with complex decorations inspired by local flora and fauna as well as European and Asian embroidery patterns. The craft was recognized at the beginning of the 18th century and was mainly produced for the European market, participating in a process of globalization.
A new study reveals that trees in the Brazilian Atlantic Forest are migrating uphill to escape rising temperatures, while some species are moving downhill. The research found that younger trees in high-altitude forests are growing more rapidly and moving uphill.
Researchers used Flora Incognita data to identify plant rhythms and ecological patterns year-round. The algorithm accounts for user observational tendencies, revealing synchronized responses among plants and ecological shifts with the seasons.
A new study found that about half of Cerrado plant species will experience a net range loss due to climate change by 2040, leading to less plant diversity in lowland areas. The research suggests that the fate of plant species depends on their geographical range, with mountain plants having nowhere to go.
Research reveals that spatial patterns in dryland vegetation are critical for adapting to changing environmental conditions. The study provides empirical evidence supporting the role of self-organized clusters in maintaining ecosystem function and health.
A new study found that the spatial arrangement of plants in drylands can be a sign of environmental degradation. Healthy ecosystems adjust their structure to cope with stressors, but degraded ones lose this adaptability and become more prone to further decline.
A new study by Prof. Ehud Meron and colleagues proposes that pairing spatial patterning and phenotypic changes is the missing link to understanding fairy circles. The researchers found that combining plant-level phenotypic changes with population-level spatial patterning can result in resilient ecosystem responses to water stress.
A study published in PLOS Medicine found that 90% of pregnant women in high-income countries lack key vitamins necessary for healthy pregnancies and fetal development. The situation is expected to worsen as more people adopt plant-based diets, leading to increased risk of nutrient deficiencies.
A Rice University scientist used a mixed-reality headset with custom-designed software to measure and analyze forest floor vegetation in Tanzania's Udzungwa Mountains National Park. The study found that mammal diversity increases with forest floor habitat surface area, leading to a greater variety of ecological characteristics.
Researchers used statistical methods to investigate the extent of climate support for the Eurasian forest-steppe zone's delineation. The study found that macroclimate explains a significant portion of the zone's distribution, with some regions showing strong agreement and others requiring further refinement.
Vegetation in North America's mountains is shifting to higher elevations at an unprecedented rate, driven by climate change. This shift is occurring faster than many animal species can adapt, with widespread changes observed across diverse ecosystems.
A multidisciplinary team will investigate how spatial patterns can prevent tipping points in ecosystems and promote resilience to climate change. The RESILIENCE project aims to identify novel directions to evade catastrophic ecosystem collapse.
A 15-year study found that the availability of beech nuts can predict bear intrusions into human habitats. The research used numerical modeling and observed beech flowering patterns to forecast bear activity, reducing direct conflicts between humans and bears.
Scientists propose a theory that large-scale vegetation patterns in arid ecosystems result from local interactions among plants and animals, rather than a single cause. Insect nests create visible clues for territory boundaries, influencing vegetation patterns.
A new theory suggests that termite engineering and vegetation self-organisation jointly create the distinctive patterns, leading to a more nuanced understanding of ecosystem interactions. The findings provide insights into regular vegetation patterns observed globally.
A study by University of Chicago paleontologist David Jablonski reveals that recoveries from mass extinctions differ significantly across geographical regions. He found varying ratios of surviving local species to foreign invaders and unique patterns of diversification, challenging previous assumptions about extinction intensity.
