Impacts of snow cover duration on vegetation spring phenology over the Tibetan Plateau

Journal of Plant Ecology, 2018
Snow cover occupies large percentage of land surface in Tibetan Plateau. Snow cover duration (SCD) during non-growing seasons plays a critical role in regulating alpine vegetation’s phenology by affecting the energy budgets of land surface and soil moisture conditions.

Civil Society Advocacy and Climate Change in Kenya: The Question of “Local Voices” and Their “Amplification”

Environmental Policy and Governance, EarlyView.
ABSTRACT The role of civil society organizations (CSOs) in addressing climate change is acknowledged, but engagement with questions of voice remains limited, especially in the Global South. Addressing this, this paper zooms in on (International) nongovernmental organizations ((I)NGOs) and their collaborations with domestic CSOs in the Global South on ...

A Novel Bipolar DC Connection Strategy for Photovoltaic Power Plants With a 50% Reduction in DC Cabling Length

Energy Science &Engineering, EarlyView.
Bipolar configuration is a new topology in the direct current (DC) system of photovoltaic power plants, which is topologically analogous to the bipolar configuration utilised in High‐Voltage Direct Current power transmission systems. DC cable length and copper usage are reduced by 50% using a bipolar configuration.

The new indices to describe temporal discontinuity of snow cover on the Qinghai-Tibet Plateau

npj Climate and Atmospheric Science
Snow cover on the Qinghai-Tibet Plateau significantly impacts the climate, hydrology, and ecology of China and East Asia. Current studies mainly use snow cover days to describe its duration, overlooking the snow’s discontinuous nature.

Potential for conflict between urban coyotes and people experiencing unsheltered homelessness

Frontiers in Ecology and the Environment, EarlyView.
Across North America, both unsheltered homelessness and human–coyote (Canis latrans) conflict are increasing, but the relationship between these phenomena has not been thoroughly explored. We synthesize literature‐based evidence with anecdotal observations that occurred during a 15‐year study of coyotes in Edmonton, Canada, to describe three likely ...

Independent leaf and root responses to autumn freezing in perennial herbs: Insights from cutting and transplant manipulations

Grassland Research, EarlyView.
In this study, we compared two sampling approaches to assess autumn freezing resistance. Our goal was to determine whether the commonly employed cutting method, which disrupts root‐tissue connectivity, provides a valid measure of true freezing resistance.

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.

Changing Water Resources in the Indus Basin: A Multi‐Model Budyko‐Based Analysis

International Journal of Climatology, EarlyView.
Budyko‐based analysis evaluates historical (1962–2005) and future hydroclimatic change across the Indus River Basin. Budyko shifts indicate rising atmospheric evaporative demand and increasing energy limitation under future scenarios. ABSTRACT Assessing hydroclimatic variability and future water availability is crucial for sustainable water‐resource ...
