Examination of phenological responses to environmental changes and improvement of phenological modeling

open access: yes, 2020
Phenology, the timing of recurring events in a plant’s life cycle, exerts strong influences on seasonal fluxes of carbon, water, and energy. In this dissertation, I investigated the responses of phenology to a variety of changes in environments and improved phenological modeling.

Topography constrains the climatic response of treeline migration in Taiwan's subalpine forests

open access: yesEcography, EarlyView.
Treelines are moving upslope, but the rates and drivers differ among different regions, globally. Many studies have examined the relationship between treeline movement and climate change, particularly rising temperature, while the role of topographical factors has received much less attention, despite the longstanding recognition of its importance.

Designing a Culture‐Driven C‐STEAM Project Framework for Vocational Education

open access: yesFuture in Educational Research, EarlyView.
ABSTRACT Amid rapid technological advances and a growing emphasis on cultural sustainability in education, STEAM education has been widely adopted to support interdisciplinary learning and decision‐making skills. However, many STEAM implementations remain largely instrumental, regularly neglecting cultural meaning‐making, value orientation, and ...

Climate change amplifies global mycotoxin exposure: Emerging risks and sustainable solutions

open access: yesiMetaOmics, EarlyView.
Climate change intensifies mycotoxin contamination through rising temperatures, elevated CO2, and altered precipitation. Global surveys reveal a high and widespread prevalence of major mycotoxins in staple cereals, with low‐income countries bearing the greatest burden.

Incorporating climate data with machine learning can improve rice phenology estimation

open access: yesEnvironmental Research Letters
Crop phenology provides essential information for crop management and production. Satellite-based methods are commonly used for phenology estimation but still struggle to capture interannual variations of phenological events.

Smart Sensor‐Integrated Lysimeter System for Affordable on‐Farm Crop Water Monitoring and Irrigation Management

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

Drought Risk in Mango and Avocado Orchards: Insights Into Plant Water Relations and Irrigation‐Related Agronomic Solutions

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Climate change is making water availability more uncertain, with growing consequences for the productivity and long‐term sustainability of tropical and subtropical fruit orchards. Mangifera indica L. and Persea americana Mill. both require large amounts of water to sustain growth and productivity.

Embedded physical constraints in machine learning to enhance vegetation phenology prediction

open access: yesGIScience & Remote Sensing
Vegetation phenology plays a pivotal role in ecological processes on terrestrial surfaces and the interactions between the biosphere and atmospheric feedback. Current attempts to retrieve vegetation phenology have primarily depended on vegetation indices
