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.

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

open access: yesIrrigation 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

open access: yesInternational 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 ...

Validity of the Landsat surface reflectance archive for aquatic science: Implications for cloud‐based analysis

open access: yesLimnology and Oceanography Letters, 2023
Originally developed for terrestrial science and applications, the US Geological Survey Landsat surface reflectance (SR) archive spanning ~ 40 yr of observations has been increasingly utilized in large‐scale water‐quality studies. These products, however,

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

open access: yesThe 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)

Forest Landscape Changes and Ecological Restoration for Sustainable Land Systems

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT This study investigates forest landscape changes and ecological restoration in Sichuan Province, China, to assess their contribution to sustainable land systems under climate stress. A theory‐guided multistage framework was applied to link Landsat‐based change detection, landscape metrics, habitat quality assessment, soil‐retention analysis ...

Predictive Ecosystem Health Assessment Under Land‐Use and Vegetation Dynamics in a Semi‐Arid Rift Valley Basin, Ethiopia

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Land degradation driven by rapid land‐use and climate‐driven vegetation dynamics increasingly threatens ecosystem stability in semi‐arid wetland basins, yet predictive ecosystem health assessments remain limited in Sub‐Saharan Africa. This study evaluates historical dynamics and future trajectories of ecosystem health in the Ziway‐Shalla Sub ...
