Green wave hypothesis
WebThe principal characteristics of radiometers intended for the measurement of short-wave radiation m a y be listed as follows (not necessarily in order of importance): (a) long-term stability, with good short-term repro- ducibility, preferably over several years; (b) relatively good degree of adherence to the Lambert cosine law (i.e., for ... WebJan 21, 2024 · The green wave hypothesis is a subset of the broader forage-maturation hypothesis that states ungulates trade off forage quantity for forage quality to maximize energy intake [5, 6]. In mountainous and high latitude regions of North America, the onset of the green wave coincides with rising daily mean temperatures causing snowmelt and ...

The bottom row shows the wave propagation from the virtual array source, of which the directional propagation is obvious. The sound energy is concentrated within a set of small angles in front of the transducer.
Webso-called green-wave hypothesis, a term first introduced in the waterfowl literature (Drent et al. 1978; Owen 1980), which it has largely remained confined to. The hypothesis refers to the migratory phenomenon whereby birds follow a wave of spring toward their summer destination, leading to the expression “surfing the green wave” (van ... WebSep 7, 2024 · The robust and general support for the Greenscape Hypothesis indicates that surfing the green wave is an adaptation to enhance foraging in environments with fleeting green-up that moves like a wave across northern temperate regions of the globe.

WebHere, we explore a basic assumption of the green wave hypothesis which states that there are successive waves of forage availability along the East-Atlantic Flyway from temperate to arctic sites, as spring advances. We use one of the migration routes of the Barnacle Goose Branta leucopsis as a model to compare data on food quality and quan ...
