Mast cells are well known for their role in allergic and anaphylactic reactions, as well as their involvement in acquired and innate immunity. Increasing evidence now implicates mast cells in inflammatory diseases where they are activated by non-allergic triggers, such as neuropeptides and cytokines, often exerting synergistic effects as in the case of

Correlated seed failure as an environmental veto to synchronize reproduction of masting plants
Highly variable, synchronized seed production, called masting, is a widespread reproductive strategy in plants. Resource dynamics, pollination success, and, as described here, environmental veto, are possible proximate mechanisms of masting.

Climate teleconnections synchronize Picea glauca masting and fire disturbance: Evidence for a fire‐related form of environmental prediction [PDF]
1.Synchronous pulses of seed masting and natural disturbance have positive feedbacks on the reproduction of masting species in disturbance‐prone ecosystems. We test the hypotheses that disturbances and proximate causes of masting are correlated, and that

The plasticity of masting: understanding how and why temporal reproductive patterns vary in trees [PDF]
Long-lived plants like trees often exhibit highly variable, yet synchronised reproduction, commonly referred to as ‘masting’. The boom-and-bust patterns of seed production have complex and far-reaching effects on regeneration and food webs. Understanding

This group compiled an extensive data base of time series for masting species with associated climatic data. Individual seed production in 59 populations of plants from 24 species spanning a large range of annual variablilty, from species exhibiting ...

Masting behaviour and dendrochronology of European beech (Fagus sylvatica L.) in southern Sweden
To identify weather controls of beech diameter growth and masting in southern Sweden, we analyze records of monthly weather, regional masting record, and tree-ring chronologies from five beech-dominated stands.

Pre-dispersal seed predation by Austral parakeets, Enicognathus ferrugineus, on pehuén, Araucaria araucana, was studied to assess the relationship between predation and seed production. We collected falling seeds in four araucaria forests of southwestern

El establecimiento de plántulas puede estar limitado por la producción de semillas y asociada a la producción intermitente y sincronizada de semillas (masting) y/o por granivoría, o por falta de micrositios aptos para la germinación y crecimiento de las ...

Identifying the mechanisms that structure niche breadth and overlap between species is important for determining how species interact and assessing their functional role in an ecosystem.
