Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (such as elevation).
The Global Plant Phenology Data Portal is an interface that allows users to see data that have been ingested by the PPO. [1] [17] It provides a way for those unfamiliar with the ontology to search for and download plant phenology data of
The BBCH-scale is used to identify the phenological development stages of plants. [1] BBCH-scales have been developed for a range of crop species where similar growth stages of each plant are given the same code.
Morren also coined the term phenology, [6] which refers to the scientific discipline that studies the seasonal cycles of animals and plants. Quetelet had established a network to observe plant flowering (referred to as anthochronology following Carl Joseph Kreutzer ) but Morren was critical of the methodology and critiqued the vagueness of the ...
Phenotypic plasticity refers to some of the changes in an organism's behavior, morphology and physiology in response to a unique environment. [1] [2] Fundamental to the way in which organisms cope with environmental variation, phenotypic plasticity encompasses all types of environmentally induced changes (e.g. morphological, physiological, behavioural, phenological) that may or may not be ...
In one example, a plant’s flowering phenology and its seed-dispersing ant mutualist’s phenology are both triggered by temperature cues. [27] Because the plant’s phenology is more prone to change under a new climate regime than the ant’s, the plant is decoupled from the selective pressure for flowering synchrony that the ant mutualism ...
