Phenological Changes in the Southern Hemisphere

PLoS ONE, 2013
Current evidence of phenological responses to recent climate change is substantially biased towards northern hemisphere temperate regions. Given regional differences in climate change, shifts in phenology will not be uniform across the globe, and conclusions drawn from temperate systems in the northern hemisphere might not be applicable to other ...

Evaluating Reference Evapotranspiration (ETo) Calculation Methods and Quantifying Climate‐Driven Change in Irrigation Demand Across Nepal's Terai

International Journal of Climatology, EarlyView.
Framework illustrating the comparison of different reference evapotranspiration (ETo) estimation methods and the integration of baseline ETo, crop water requirement (CWR), and irrigation water requirement (IWR) calculations with downscaled CMIP6 climate projections under SSP245 and SSP585 scenarios for the mid‐century and late‐century periods across ...

Long‐Term Analysis of Winter Wheat Yield and Climatic Influences in Ukraine

International Journal of Climatology, EarlyView.
Long‐term field data (1968–2024) show that winter wheat yields in central Ukraine increased despite warming, but yield stability declined. Rising temperatures, more frequent soil moisture droughts and shortened winter calm increasingly limit productivity.

Phenological Predictability Index in BRAHMS: a tool for herbarium‐based phenological studies

Ecography, 2012
Phenological Predictability Index (PPI) is a tool for analysing phenological patterns incorporating herbarium data within BRAHMS (Botanical Research and Herbarium Management System). PPI produces a maximum‐activity period and associated event predictability index between ∼0 and 1.

Assessing plant water status: Part 2 – Non‐destructive and remote sensing approaches

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Precise, real time and non‐destructive assessment of plant water status is important for advancing plant physiological understanding, optimizing water usage, improving crop resilience and supporting precision agriculture in the face of increasingly variable climatic conditions.

Modeling the Evolution of Insect Phenology

Bulletin of Mathematical Biology, 2008
Climate change is likely to disrupt the timing of developmental events (phenology) in insect populations in which development time is largely determined by temperature. Shifting phenology puts insects at risk of being exposed to seasonal weather extremes during sensitive life stages and losing synchrony with biotic resources.

Habitat characteristics along spring migration routes of elk, mule deer, and pronghorn in the southern San Juan Mountains

The Journal of Wildlife Management, EarlyView.
We evaluated habitat characteristics of spring migration routes and stopover sites for adult female elk (Cervus canadensis), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana) in the San Juan Mountains (2021–2022) and found species‐specific differences in vegetation structure, terrain, and proximity to land cover types relative to ...

Effects of off‐highway vehicle activity on Arizona wildlife: a systematic literature review

The Journal of Wildlife Management, EarlyView.
The published literature indicates that off‐highway vehicles (OHVs) predominantly negatively affect native Arizona amphibians, mammals, and reptiles, while effects of OHVs on native Arizona birds are mostly unknown or neutral. Abstract Off‐highway vehicle (OHV) recreation has dramatically increased in Arizona, USA, prompting concerns about potential ...

Simulated Root Exudation Gradient Reveals Dosage‐Dependent Carbon Sequestration in Desertification Ecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Root exudates serve as a key driver for the restoration of soil organic carbon (SOC), particularly in aeolian desertification ecosystems where aboveground litter retention is limited. While Salix cupularis is widely planted as an effective pioneer shrub for ecological rehabilitation on the Qinghai‐Tibet Plateau, how the quantity of its root ...
