Constrained growth flips the direction of optimal phenological responses among annual plants.
Phenological changes among plants due to climate change are well documented, but often hard to interpret. In order to assess the adaptive value of observed changes, we study how annual plants with and without growth constraints should optimize their flowering time when productivity and season length changes. We consider growth constraints that depend on the plant's vegetative mass: self-shading...
متن کاملNew Phytologist Supporting Information: Constrained growth flips the direction of optimal phenological responses among annual plants
We first show the influence of mortality on our model predictions as a robustness check, and second we show that the optimal control is of bang-bang type, with one unique switch, for annuals with constrained growth, fixed season length, and constant mortality. As a robustness check we extend the model with constant background mortality rate m. We assume that the vegetative part grows according ...
متن کاملPhenological Patterns of Terrestrial Plants
The term phenology is derived from the Greek word phaino meaning to show or to appear. Hence, phenology is defined as the study of the seasonal timing of life cycle events. For plants the seasonal timing of such events can be critical to survival and reproduction. In agriculture the most common failure of introduced crops is the inability to adjust to the seasons imposed by the new, environment...
متن کاملPhenological responses of prairie plants vary among species and year in a three-year experimental warming study
As temperature is a common regulator of temperate plant phenology, future increases in global temperatures are likely to cause shifts in the timing of plant phenophases such as flowering and senescence, with potential feedbacks on species interactions and carbon cycling. We used a 3-year field warming study in a temperate grassland to investigate the effects of two levels of warming (þ;1.58C an...
متن کاملOptimal phenology of annual plants under grazing pressure.
Plants show phenological responses to herbivory. Some enclosure experiments have demonstrated that the onset of the peak flowering season is dependent on grazing pressure. We constructed a mathematical model using Pontryargin's maximum principle to investigate changes in flowering time by examining shifts in resource allocation from vegetative to reproductive plant components. We represented a ...
