Understanding vegetation phenology and productivity responses to environmental forcings are of great importance in global change studies. Vegetation phenology and productivity responses to climate extremes, however, are complex with variable magnitude and directional responses across seasons, along climatic gradients, and among by: Phenology is the study of the timing of seasonal biological events, such as the flowering of plants or the migration of birds. For example, you are observing phenology when you note when your favorite plant beings to flower each year, or when your favorite migratory bird arrives at your feeder in the spring.
These studies investigated dozens of tree, shrub and vine species, and found that the extent of spring warming strongly affected leaf-out phenology in all species studied. In contrast, the influence of winter chilling was highly variable among species, and photoperiod affected only a limited number of by: Phenological events, such as the initiation and the end of seasonal growth, are thought to be under strong evolutionary control because of their influence on tree fitness. Although numerous studies highlighted genetic differentiation in phenology among populations from contrasting climates, it remains unclear whether local adaptation could restrict phenological plasticity in response to Cited by:
Climate models forecast the decrease in annual precipitation and more extreme events (i.e. fewer rainy days and longer drought periods between rainfall events) in Mediterranean ecosystems which may have important consequences for plant community dynamics.

Phenological and reproductive responses of a semiarid shrub to pulsed watering. Climate models forecast decrease in annual precipitation and more extreme events (i.e., fewer rainy days and longer drought periods between rainfall events) in Mediterranean ecosystems which may have important consequences for plant community dynamics.
We explore the relationships between environmental factors and vegetative and reproductive phenology in nine dominant perennial plant species in a semi-arid ecosystem in central Mexico. In spite of the highly seasonal environment at the study site, and a relatively long dry period, at least one species was always in some phase of growth or Cited by: Colophospermum mopane, commonly known as mopane, is a dominant tree or shrub in the mopane woodland.
It is widely distributed in the low-lying areas of southern Africa's savanna. Despite its wide distribution, ability to survive water stress conditions, and value as a source of browse for herbivores, especially during the dry season, there is limited knowledge on mopane leaf production and.
The timing and development of green leaves, plant maturity, and senescence affects biophysical interactions of plants with the environment. In this study we explored the agreement between land-based camera and satellite-based phenology metrics to quantify plant phenology and phenophases dates in five plant community types characteristic of the semi-arid cold desert region of the Great by: 2.
Phenology (from the Greek phainein, to show or appear) is the study of the timing of these life-history events. In plants, bud-burst, leaf-expansion, abscission, flowering, fertili- sation, seedset, fruiting, seed dispersal and germination all take place in due by: Phenology of flowers, seeds, and fruits in a tropical forest tree.

Spatiotemporal patterns of vegetation phenology change and relationships with climate in the two tra Changes in vegetation phenology due to global climate change directly impact the dynamic balance of terrestrial carbon and nutrients and the biodiversity pattern, and send feedbacks to climate system.
Phenology offers critical insights into the responses of species to climate change; shifts in species’ phenologies can result in disruptions to the ecosystem processes and services upon which human livelihood depends. To better detect such shifts, scientists need long-term phenological records covering many taxa and across a broad geographic distribution.
To date, phenological observation Cited by: Phenology, the study of different phases in the life-cycle of a plant consists of seedling, vegetative and reproductive stages. While growth of leaves and stems are studied under vegetative.
What is Phenology. Phenology is the study of the timing of the biological events in plants and animals such as flowering, leafing, hibernation, reproduction, and migration. Scientists who study phenology are interested in the timing of such biological events in relation to changes in season and climate.
However, most published studies of shifts in plant community phenology have been from humid-temperate climates (i.e., western Europe, eastern North America; but see Peñuelas et al., ). The purpose of our study is to examine changes in wildflower phenology between and in the semi-arid climate of intermountain western North by: Advances in plant flowering and leafing times in response to warming are underpredicted by experimental warming studies.

This study was estimated for different plant communities in a semi‐arid. Abstract. This chapter deals with both traditional aspects of phenology in agriculture (length of growing season and different applications of phenological data in agriculture) as well as modern aspects, which focus on impacts of climate change on phenophases of field crops and fruit by: Forest phenology refers to the timing of natural events through the seasons.
These events include flushing or budburst, flowering, fruiting, and autumn leaf-fall. Phenology is partly driven by amounts of light, water, and temperature, but also by tree genetics.
