Researchers at the University of Tokyo and Kozo Keikaku Engineering Inc. have introduced a method for enhancing the power of existing algorithms to forecast the future of unknown time series by combining suboptimal forecasts. This approach was tested on real-world flood data and theoretical equations with chaotic behavior, resulting in...
A simple epidemiological model accurately predicts measles transmission dynamics in London over almost a century, accounting for historical events like the 1918 pandemic. The study's findings suggest long-term disease dynamics can follow simple rules, with implications for understanding other ecological phenomena.
Research on coralline algal diversity reveals fewer species and less diversity in urchin barrens compared to kelp forests with sea otters. The study suggests that cryptic species identification alters ecosystem dynamics perception.
A team of scientists from the University of Leicester has explored the long-standing mystery of mass extinctions, revealing that abrupt transitions can occur due to 'ghost attractors' and 'crawl-bys'. This knowledge could help predict upcoming ecological catastrophes and inform efficient management.
A new tool called EcoCast uses satellite data, maps, and observations to help fishers locate the most productive fishing spots while avoiding protected species. The study shows that this approach can be up to 10 times more efficient in protecting species than previous management styles.
Researchers developed an epidemiological model to study the effect of climate warming on host-parasite dynamics in Eurypanopeus depressus and its parasitic barnacle Loxothylacus panopaei. Infection prevalence declined at a 1°C temperature increase, with localized extinction occurring at 2°C warming in the southeastern United States.
A team of scientists from UC Santa Barbara tested the effect of sulfurized nano-zero-valent iron on a common freshwater alga and found that it picked up cadmium and alleviated toxicity. Organic material produced by the algae mitigated the nanoparticle's toxicity, allowing for greater remediation.
A decade-long study in Southeast Brazil's Atlantic Forest reveals reduced biodiversity and diminishing ecosystem services due to cattle farming and expanding agricultural land areas. Key findings include the importance of trees larger than 20 cm in diameter for biomass accumulation.
Researchers from the University of Groningen have developed a conceptual model to describe the dynamics of microbial populations during plant biomass degradation. This model reveals different phases and stages, where distinct microbial species are crucial for breaking down plant biomass into simple sugars.
The LSU Center for Coastal Resiliency has received $1.3 million in grants to support research on coastal resiliency and sea level rise risks. The projects aim to develop large-scale computer models that can predict coastal dynamics and assess hydrodynamic and ecological impacts.
Researchers found universal (host-independent) dynamics for healthy individuals' gut and mouth microbiomes. Fecal microbiota transplantation therapy also relied on these shared patterns to treat C. difficile infections.
Researchers have developed a model to predict the risk of waterborne diseases in flooding rivers, which can affect millions of people worldwide. The study's findings highlight the importance of understanding the complex interactions between environmental and human factors in shaping disease dynamics.
Carlos Castillo-Chavez receives SIAM Prize for his distinguished service to the profession and contributions to applied mathematics. He has made significant impacts in disease dispersal, addiction, and complex systems through his research at Arizona State University.
Researchers urge caution when exploring/exploring the deepest parts of our oceans, highlighting the need for a 'happy balance' between use and environmental costs. The deep ocean is already experiencing impacts from human activities such as fishing, oil and gas development, and waste disposal.
Symposia focus on ecological dynamics of infectious diseases, examining human influences on viral and bacterial diseases through landscape alteration. Researchers aim to integrate biomedical and ecological approaches to address public health issues.
The National Science Foundation has awarded $17.6 million in grants to researchers exploring how humans and the environment interact, with a focus on invasive species, climate change, and sustainability.
Researchers from UT Austin are part of a $3 million NSF Delta research collaboration to build comprehensive computer models for predicting river delta evolution. The project aims to understand how deltas respond to human activities and learn to direct delta evolution.
A new appreciation of the ecology-evolution dynamic reveals that environmental factors can influence evolutionary changes and shape ecological traits. This emerging field of study highlights the interconnectedness between ecology and evolution, suggesting a feedback loop where ecological changes affect evolution and vice versa.
A new mathematical model explores the emergence and collapse of complex societies via warfare, revealing that stability is strongly promoted by wealth, power, and well-defined succession mechanisms. The model also predicts 'chiefly cycles' of rapid growth and collapse due to warfare, which can occur without environmental disturbances.
A team of ecologists highlights the importance of combining environmental conditions with climate models to predict species distribution. Paleoecological studies show that past climate variability has affected tree species distributions, and future changes in climate variability need to be considered when predicting species responses.
Ecologist and Princeton Professor Simon Levin emphasizes the importance of self-organization in ecosystems and the interface between ecology and economics. His lecture at SIAM Annual Meeting explores mathematical approaches to uniting ecology and socioeconomics for a sustainable future.
A study by Saskia van Vuren reveals that changes in the riverbed elevation can cause high-water problems, flooding, droughts, erosion, and affect discharge distribution. The researcher argues that future high-water level predictions must consider morphological dynamics.
The American Geosciences Institute announced winners of the Earth Science Week contest, showcasing artistic talents in visual arts, essay writing, and photography. The contests aimed to increase public awareness of geology and the earth sciences.
The National Science Foundation has funded six projects under its Ecology of Infectious Diseases program to understand the ecological and biological mechanisms behind relationships between human-induced environmental changes and infectious disease emergence. The research will focus on understanding disease transmission, unintended heal...
A new study suggests a dynamic business plan approach to conservation, prioritizing opportune land acquisitions and leveraging market dynamics to safeguard habitats. The authors aim to improve the effectiveness of protected area networks in addressing the rapid decline of highly threatened vertebrates.
The study's findings suggest that current conservation planning approaches may be hindering species protection. Instead, scientists recommend a more dynamic business plan approach, leveraging market uncertainty and landowner motivation to safeguard habitat for highly threatened species.
A new study published in Ecology Letters suggests that El Niño impacts ecological dynamics in the Northern Hemisphere. The research found concurrent effects of NAO and ENSO on the long-term dynamics of a natural population, including the globally threatened White-headed Duck in Spain.
Community invasibility is influenced by resident species composition and community cover. The relationship between richness and invasion dynamics reveals a more complex process than previously thought.
Ranchers are adapting to environmental changes by incorporating conservation techniques, such as managing grazing patterns and using native species. The symposium showcases successful examples of progressive management, including the use of beavers to restore woodlands and improve biodiversity.
