Bee phenology is predicted by climatic variation and functional traits.
Ecology Letters, 2020Climate change is shifting the environmental cues that determine the phenology of interacting species. Plant-pollinator systems may be susceptible to temporal mismatch if bees and flowering plants differ in their phenological responses to warming ...

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 trees.

The nature and extent of phenological variability among individuals of sumac, Rhus glabra, was investigated. The phenological events considered are: bud elongation, bud opening, leaf appearance, cessation of leaf and twig growth, inflorescence appearance, first flower and fruit, and cessation of inflorescence growth. The sex of the clone, height of the

Climate change impacts on mismatches between phytoplankton blooms and fish spawning phenology
Global Change Biology, 2019Substantial interannual variability in marine fish recruitment (i.e., the number of young fish entering a fishery each year) has been hypothesized to be related to whether the timing of fish spawning matches that of seasonal plankton blooms ...

The annual growth cycle of fruiting grapevines is divided into a vegetative and a reproductive cycle. Fruit production extends over 2 years: buds formed in the first year give rise to shoots bearing fruit in the second year. Seasonal growth is driven by day length and temperature, and alternates with winter dormancy.

In Chapter 5 of this book, it is shown that the formation of ice on the surface of a lake (‘ice-on’) and its thawing and ultimate disappearance (‘ice-off’) are complex phenomena governed by mechanisms that involve many interacting meteorological (and some non-meteorological) forcing factors. Linking ice phenology – the timing of ice-on and ice-off – to

The chapter describes methodologies for harmonized phenological assessments based on a limited set of development phases: flushing, flowering, secondary flushing, color change, and leaf/needle fall. Manual phenological observations are based on a brief examination in the forest stands. More recently, the use of terrestrial digital image photography for

The agricultural phenologist studies the impact of climate and soil conditions on the timing of biological events in plants of commercial and ornamental importance. The studies may include forests and pastures, as well as food crops. Phenophases observed include economic elements like harvesting and marketing of commercial plants; and in this respect ...
