Article Synopsis
- Despite advancements in machine learning, current systems struggle with real-world variability, requiring adaptation to new conditions and tasks.
- A proposed solution is "Lifelong Learning" systems that emphasize Continuous Learning, Transfer and Adaptation, and Scalability, yet research often treats these capabilities separately.
- The authors advocate for a holistic evaluation framework using a comprehensive set of metrics to assess the development of Lifelong Learning systems, demonstrating how these metrics can identify performance trade-offs and guide future research efforts.
Management of waterfowl that migrate seasonally across North America occurs within four flyways that were delineated in the early 1900s to include the annual movements of populations. Movements may have changed over the past century since the administrative flyways were established, and may do so while management plans are in use, so information about transitions among flyways through time can illustrate how management assumptions may change. Today there are more than 12 million records from 60 years of migratory waterfowl band recoveries to assess adaptive management approaches that will be most effective when they account for movements within and between flyways.

We used data collected by a UAS and a Bayesian closed capture-mark-recapture model to estimate abundance and distribution while accounting for imperfect detection of aggregated Florida manatees (Trichechus manatus latirostris) at thermal refuges to assess use of current and new warmwater sources in winter. Our UAS hovered for 10 min and recorded 4 K video over sites in Collier County, FL.

- Age-specific survival probabilities are crucial for age-structured population models and conservation efforts, but determining individual ages in wildlife can be challenging.
- The researchers introduced a hidden Markov model designed to estimate these probabilities using capture-recapture data and imprecise age indicators, tested through simulations and applicable with maximum likelihood and Bayesian methods.
- This model was successfully applied to Florida manatees' genetic capture-recapture data, highlighting its usefulness in understanding how environmental changes and management strategies affect population dynamics through minimally invasive techniques.
