Long-term ecological monitoring is a methodological framework involving repeated, standardized measurements of biotic and abiotic variables over extended timescales (typically decades) to quantify ecological dynamics, detect trends, and assess responses to natural variability and anthropogenic perturbations. It relies on consistent sampling designs, fixed plots or stations, calibrated instrumentation, and strict protocols to ensure temporal comparability and statistical robustness. Core components include selection of indicator species or ecosystem attributes, temporal replication sufficient to capture slow processes and rare events, and integration with metadata, quality control, and archiving systems. These methods enable inference about ecosystem resilience, regime shifts, and long-term trajectories, and often underpin validation of ecological models and environmental policy assessments.
Insufficient monitoring leaves gaps in our knowledge of Antarctica's unique lifeforms and ecosystems—and their global significance. A new paper led by University of Wollongong researchers calls for the urgent expansion of ...

North American river otters have terrible hygiene when it comes to their food. They eat, play and defecate in the same place. But their unhealthy habits make them ideal for detecting future health threats in the environment, ...
