Plant ecology

Trees seeding heavily in synchronised pulses

In plant ecology mast (or masting) is the synchronised, highly variable production of seed by a population of perennial plants (oaks or beeches that flood the forest with acorns in a 'mast year' and produce almost nothing in between). Kelly's 1994 The evolutionary ecology of mast seeding set out the leading explanations, from satiating seed predators to improving pollination efficiency in wind-pollinated trees. The referent is a reproductive pattern measured across years and individuals, carrying no connection to an immune cell or a ship's spar other than the word; 'mast' here descends from the Old English term for forest nuts eaten by swine.[1]

Unit
Year-to-year, across-plant variation in seed crop size
Recovery means
Not applicable
Measured by
Quantified by the coefficient of variation of annual seed output and the spatial synchrony of crops across individuals

Immunology

A granule-packed cell that drives allergic response

In immunology a mast cell is a tissue-resident immune cell packed with granules of histamine and other mediators, central to allergy, anaphylaxis, and defence against parasites; Paul Ehrlich named them Mastzellen ('well-fed cells') in 1878 for their gorged, granule-stuffed look. Galli and colleagues' 2005 review Mast cells as 'tunable' effector and immunoregulatory cells recasts them as finely adjustable regulators rather than simple histamine bombs. The referent is a cell type defined by its lineage, granules, and signalling, sharing only its name (and Ehrlich's 'well-fed' image) with a seed crop or a ship's spar.[2]

Unit
The cell population, described by density, granule content, and mediator release
Recovery means
Not applicable
Measured by
Characterised by tissue mast-cell counts, granule and mediator content, and degranulation on activation
