Neural Earthquake Forecasting with Minimal Information: Limits, Interpretability, and the Role of Markov StructureNARA Subscribed
Forecasting earthquake sequences remains a central challenge in seismology, particularly under non-stationary conditions. While deep learning models have shown promise, their ability to generalize across time remains poorly understood. We evaluate neural and hybrid (NN + Markov) models for short-term earthquake forecasting on a regional catalog using temporally stratified cross-validation. Models are trained on earlier portion...
Under the current global biodiversity crisis, there is a need for automated and noninvasive monitoring techniques that can gather large amounts of data cost‐effectively at various ecological scales, from local to large spatial scales. These data can then be analyzed to inform stakeholders and decision‐makers. One such technique is passive acoustic monitoring, which is commonly coupled with automatic identification of animal sp...
Two b’s or Not Two b’sNARA Subscribed
The b -value, a crucial parameter in the Gutenberg–Richter magnitude distribution, plays a pivotal role in understanding seismic activity. Its significance stems primarily from its inverse correlation with stress levels in the Earth’s crust, offering valuable insights into the underlying forces that drive earthquake occurrences. It is often observed that the Gutenberg–Richter histogram presents two different slopes, with highe...
Soil microbial activity is a key indicator of soil health, traditionally assessed using methods like enzymatic activity, community-level physiological profiling (CLPP), microbial biomass, and soil respiration. This study introduces isothermal microcalorimetry assessed with the CalScreener™ system as a novel tool for evaluating soil activity and validates its use in assessing the impact of anthropogenic pollutants like micropla...
Nutrients on the move: Investigating large scale fatty acid exports from European ponds via emerging insectsNARA Subscribed
Permanent ponds are key landscape units that supply various ecosystem services. Notably, the export of aquatic subsidies to land via emerging insects may significantly influence terrestrial food webs. Polyunsaturated fatty acids (PUFA), which enhance consumer fitness, are among the essential exported components. The patterns and drivers of dietary exports from ponds via insects remain poorly known, particularly at continental...
Dominance and rarity in tree communities across the globe: Patterns, predictors and threatsNARA Subscribed
Aim Ecological and anthropogenic factors shift the abundances of dominant and rare tree species within local forest communities, thus affecting species composition and ecosystem functioning. To inform forest and conservation management it is important to understand the drivers of dominance and rarity in local tree communities. We answer the following research questions: (1) What are the patterns of dominance and rarity in tree...
Bacterial septicemia and herpesvirus infection in Antarctic fur seals (Arctocephalus gazella) stranded in the São Paulo coast, BrazilNARA Subscribed
In August 2021, two juvenile male Antarctic fur seals ( Arctocephalus gazella ) stranded in the southeastern Brazilian coast and were referred to rehabilitation centers. The animals presented increased body temperature, prostration, respiratory distress and despite treatment died. A necropsy following a standardized protocol was performed, and formalin-fixed tissues were processed for microscopic examination. Samples were scre...
