What phenology means?

Phenology is defined as the study of the timing of recurring biological events, the causes of their timing with regard to biotic and abiotic forces, and the interrelation among phases of the same or different species (Leith 1974).

What is vegetation phenology?

Vegetation phenology—the seasonal progression of plant activity through stages of dormancy, active growth, senescence, and back to dormancy—is a key regulator of both ecosystem processes and biosphere feedbacks to the climate system1,2.

What is phenology example?

Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of migratory birds, the date of leaf colouring and fall in deciduous trees, the dates of egg-laying of birds and amphibia, or the timing of the developmental cycles of temperate-zone honey bee colonies.

Who uses phenology?

Critical applications of phenology include: Management of invasive species and forest pests. Predictions of human health-related events, such as allergies and mosquito season. Optimization of when to plant, fertilize, and harvest crops. Understanding the timing of ecosystem processes, such as carbon cycling.

What is an example of phenology?

What is vegetation phenology and why is it important?

Phenology is an important indicator of vegetation dynamics and plays an important role in vegetation activity, energy exchange and ecosystem functions. Vegetation phenology has substantially changed under climate change effects and affected the seasonality of the ecosystem process.

What is a phenological trait?

A plant phenological trait is defined as “A ‘quality’ of a ‘whole plant’ that provides phenologically relevant information about the plant”. Phenological traits in the PPO are defined in terms of one or more plant structures associated with the trait.

Why is phenology useful?

Phenology is a key component of life on earth. Phenology influences the abundance and distribution of organisms, ecosystem services, food webs, and global cycles of water and carbon. In turn, phenology may be altered by changes in temperature and precipitation.

What happens if phenology changes?

If the phenology of a species is shifting at a different rate from that of the species that make-up its ecological conditions, this will lead to mistiming of its seasonal activities (Visser et al. 2004) or, to use an alternative terminology, to a mismatch in phenology (Stenseth & Mysterud 2002).

What does phenology mean and why is it important?

Phenology is nature’s calendar—when cherry trees bloom, when a robin builds its nest and when leaves turn color in the fall. Phenology is a key component of life on earth. Changes in phenological events like flowering and animal migration are among the most sensitive biological responses to climate change.

What causes phenology?

Across the world in all classes of plants and animals, phenological shifts are happening because of these climatic changes that result from global warming. For most plants and animals, these phenological events are happening earlier each year. For some species, they’re are being delayed.

What is phenology and its classification?

Phenology defined as the ‘observation and investigation of the seasonal timing of life cycle events’ and how these are influenced by seasonal variations in climate, as well as other ecological factors (1). Longer records, at least 5 years, are needed to examine trends of the life cycle.

Which is the best definition of the term phenology?

Phenology. In the scientific literature on ecology, the term is used more generally to indicate the time frame for any seasonal biological phenomena, including the dates of last appearance (e.g., the seasonal phenology of a species may be from April through September).

Which is an example of phenology in a tropical forest?

Phenology is defined as the study of the timing of recurring biological events, the causes of their timing with regard to biotic and abiotic forces, and the interrelation among phases of the same or different species (Leith 1974). Phenology in tropical forests is dominated by rainfall-related events.

Which is an example of remote sensing based phenology?

A noteworthy example of the use of remote sensing based phenology is the work of Ranga Myneni from Boston University. This work showed an apparent increase in vegetation productivity that most likely resulted from the increase in temperature and lengthening of the growing season in the boreal forest.

Why is phenology a sensitive indicator of climate warming?

Phenology, or repeated seasonal life-cycle events such as annual migrations or spawning, is highly a sensitive indicator of climate warming. This is because many terrestrial and marine organisms, apart from photoperiod, are dependant on temperature as a trigger for seasonal behaviour.
