Towards a global leaf phenology model

2023
Leaf phenology, often measured by the seasonal dynamics of leaf area index (LAI), is a key control on the exchanges of CO2 and energy between land ecosystems and the atmosphere. It is therefore also a key target process for dynamic vegetation models. However, there is no agreement on how leaf phenology should be modelled.

Weather Station Siting: Effects on Phenological Models

2013
Accurate temperature data is important for both the development and use of phenological models, and this chapter discusses topics related to temperature measurement for use in phenological models. The chapter presents a short history of temperature measurement, the theory of temperature sensors, radiation shielding, and guidelines on weather sensor ...

Phenology and Seasonal Modeling in Insects

1974
Insects exhibit a wide variety of seasonal adaptations. Studies of seasonality in insects have generally considered whole populations rather than repeated observations of individuals. The reason for this approach is that insects, as a rule, are small, short-lived, and extremely abundant.

Modeling Grasshopper Phenology with Diffusion Processes

1989
Understanding the development of pest insects is central to any integrated management system. Development in insects is characterized by a progression through a variable number of discrete stages. The compelexity and number of stages depend in part on whether they are hemi — or holometabolous. With rangeland grasshoppers, for example, most species pass
