Mast cells and basophils [PDF]
Mast cells and basophils are effector cells in IgE-associated immune responses, such as those that contribute to asthma and other allergic diseases and to host resistance to parasites. Recent work shows that mast cells can also participate in innate immunity to bacterial infection and that the expression of such mast cell-dependent natural immunity can

Escaping seed predation is a classic "economy of scale" hypotheses (predator satiation hypothesis, Psh) to explain the selection for the synchronous production of massive and nil seed crops (masting) in plants.

Masting behaviour in beech: linking reproduction and climatic variation
The question of what triggers masting in beech (Fagus) has been a source of uncertainty and curiosity. Analysing seed production series from Europe (Fagus sylvatica L.), eastern North America (Fagus grandifolia Ehrh.), and Japan (Fagus crenata Blume ...

Masting in whitebark pine (Pinus albicaulis) depletes stored nutrients
International audienceIn masting trees, synchronized, heavy reproductive events are thought to deplete stored resources and to impose a replenishment period before subsequent masting.

The predator satiation (PS) hypothesis of masting holds that seeding periodicity among plant populations enhances seed survival by starving granivores during low-output periods and satiating reduced consumer populations during mast (high-output) years ...

Pollination, a key component of masting in temperate oak species
Le « masting » correspond à une dynamique de fructifications, commune chez de nombreuses plantes pérennes, et caractérisée par une production de fruits extrêmement fluctuante d’une année à l’autre et synchronisée à l’échelle populationnelle.

Rodent outbreaks and extreme weather events: a southeast Asian perspective
In recent reviews of rodent outbreaks (Singleton et al., 2010a,b), three general systems were identified that influence the food supply of rodents in significantly different ways. One is life-cycle- or evolutiondriven in the form of plant masting events.
