Study of yield components under heat stress conditions in wheat [PDF]

, 2013
High temperature tolerance can be characterised by measuring various plant productivity traits in different developmental stages. The present work investigated the effect of exposure to high temperature (30-35°C) at first node appearance, during ...

Flowering out of sync: Climate change alters the reproductive phenology of Terminalia paniculata in the Western Ghats of India

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how climate change impacts the plant life cycle is critical for maintaining biodiversity and ecosystem services. Our findings suggest that Terminalia paniculata Roth, a common tropical deciduous tree species in the Western Ghats, is now flowering and fruiting at more scattered times than it used to in the past.

Phenological Gardens Protocol [PDF]

, 2003
The purpose of this resource is to observe the flowering and leaf stages of selected garden plants throughout the year. After a phenological garden is planted, students observe the growth of leaves and blooming of flowers on the plants. These plants were

Leveraging machine learning and citizen science data to describe flowering phenology across South Africa

PLANTS, PEOPLE, PLANET, EarlyView.
Recent shifts in flowering times are an index of, and a response to, human driven climate change. However, most information on these flowering changes is heavily skewed to the northern hemisphere. This imbalance limits our understanding of how climate change is affecting ecosystems, including the mismatches of flowering times between species, increased

Combining Spectral Libraries and 3-D Radiative Transfer Modeling to Improve the Simulation of Phenology in Semi-Arid Grasslands

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Semi-arid grasslands and savannas are essential for human well-being, and are particularly affected by climate change effects. Remote sensing data offers the possibility to survey the evolution of these ecosystems through the estimation of vegetation ...

Phenophases and cutting time of forage cactus under irrigation and cropping systems [PDF]

Pesquisa Agropecuária Tropical, 2017
ABSTRACT Management practices can affect the phenology and, consequently, the harvest time and crop production level of forage cactus. This study aimed at evaluating the effect of irrigation depths and cropping systems on the phenophases and cutting time of the forage cactus Opuntia stricta (Haw.) Haw.

Time‐series digital camera photos combined with machine learning algorithms can realize accurate observation of flowering phenology

Remote Sensing in Ecology and Conservation, EarlyView.
Intelligent approaches are required to extract valuable phenological information from time‐series digital camera photos. In this research, we employed YOLO‐based object detection and semantic segmentation models to identify flowers and flower pixels, acquire flower count and flower cover data, and extract phenophases such as first, peak, and end ...

Inter-comparison of satellite sensor land surface phenology and ground phenology in Europe [PDF]

, 2015
Land surface phenology (LSP) and ground phenology (GP) are both important sources of information for monitoring terrestrial ecosystem responses to climate changes.

Phenological responses to climate change: advancing mating and calving in wild and semi‐captive Caspian red deer

Wildlife Biology, EarlyView.
Species respond to climate change through phenological and spatial shifts. Herbivorous mammals, in particular, are vulnerable due to their direct dependence on seasonal vegetation and the potential misalignment between their reproductive cycles and shifting food availability.
