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

Ecography, 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.

Fusion of Landsat 8 OLI and Sentinel-2 MSI Data [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2017
Sentinel-2 is a wide-swath and fine spatial resolution satellite imaging mission designed for data continuity and enhancement of the Landsat and other missions. The Sentinel-2 data are freely available at the global scale, and have similar wavelengths and the same geographic coordinate system as the Landsat data, which provides an excellent opportunity

Evapotranspiration Estimation and Irrigation Performance Assessment Using Remote Sensing: A Case Study of the Ergani Dam Irrigation System (Turkey)

Irrigation and Drainage, EarlyView.
ABSTRACT Efficient water resource management is critical for sustainable agriculture, with evapotranspiration (ET) serving as a key parameter. Remote sensing (RS) techniques offer cost‐effective approaches for ET estimation and irrigation performance assessment in extensive agricultural systems.

Characterising City Scale Heat Climatology for Australian Climate Zones

International Journal of Climatology, EarlyView.
The Urban Heat Island (UHI) effect in Australian cities peaks at night, intensifying under dry conditions, clear skies, increased solar radiation, and low wind speeds. Long‐term observations show that nighttime temperatures in major cities have warmed faster than their rural surroundings and future climate projections fail to capture this disparity ...

Landsat 8 Virtual Orange Band for Mapping Cyanobacterial Blooms

Remote Sensing, 2020
The Landsat 8 Operational Land Imager (OLI) has a panchromatic band (503−676 nm) that can be used to derive a novel virtual orange band (590−635 nm) by using the multispectral green band and red band components.

Annual survival and resource selection of juvenile male wild turkeys in central Tennessee

The Journal of Wildlife Management, EarlyView.
Juvenile male wild turkeys in central Tennessee, USA, selected areas with smaller patch sizes and lower proportions of developed land. Annual survival was 0.73 and decreased as dense land cover such as young and deciduous forest increased and cover types with high visibility decreased. Abstract Documenting juvenile male wild turkey (Meleagris gallopavo)

Coupling Water Purification and Carbon Sequestration at Various Spatial Scales From Supply and Demand Perspective

Land Degradation &Development, EarlyView.
ABSTRACT Balancing ecosystem‐service supply and demand is central to understanding both the natural and social dimensions of ecosystem services and to enhancing human well‐beings. Concurrently, collaborative efforts are underway to improve multiple ecosystem services, including the promotion of carbon neutrality and water purification (WP) within basin
