ERTS-1 evaluation of natural resources management applications in the Great Basin [PDF]

The relatively cloud free weather in the Great Basin has allowed the accumulation of several dates of excellent ERTS-1 imagery. Mountains, valleys, playas, stream courses, canyons, alluvial fans, and other landforms are readily delineated on ERTS-1 ...

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

Fish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Intercomparison of phenological transition dates derived from the PhenoCam Dataset V1.0 and MODIS satellite remote sensing [PDF]

, 2018
Phenology is a valuable diagnostic of ecosystem health, and has applications to environmental monitoring and management. Here, we conduct an intercomparison analysis using phenological transition dates derived from near-surface PhenoCam imagery and MODIS

Diverging Spring Warming and Growing Season Shifts Across Eurasia and North America Under Future Climate

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Springtime warming over Northern Mid‐High‐latitude Land profoundly affects plant life cycles and water resources, yet large model uncertainty limits climate risk assessment. Here, we develop a novel emergent constraint that targets the key uncertainty source—model divergence in surface‐albedo feedback linked to historical snowmelt sensitivity.

Phenology, growth, and fecundity of eight subarctic tundra species in response to snowmelt manipulations [PDF]

, 2018
The snow cover extent is an important factor for the structure and composition of arctic and alpine tundra communities. Over the last few decades, snowmelt in many arctic and alpine regions has advanced, causing the growing season to start earlier and ...

More Rapid Reduction of Spring Snow Cover on the Western Tibetan Plateau by Emergent Constraint

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Snow cover is a critical component of climate, hydrological, and ecological systems, particularly in high‐altitude and high‐latitude regions. Global warming has driven substantial snow cover retreat, yet projections from climate models vary widely, hindering reliable climate change adaptation and policy planning.

Combined Effects of Air Humidity and Temperature on Biogenic Volatile Organic Compound Emissions and Photosynthesis

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract Temperature and air humidity are critical environmental factors regulating photosynthesis and biogenic volatile organic compound (BVOC) emissions from plants, which influence air quality and climate change. While previous research has demonstrated the impacts of temperature on photosynthesis and BVOCs, the effects of humidity and the combined ...
