Dissecting components of population-level variation in seed production and the evolution of masting behavior. – Oikos 102: 581–591. Mast-fruiting or masting behavior is the cumulative result of the reproductive patterns of individuals within a population and thus involves components of individual variability, between-individual synchrony, and endogenous cycles of temporal… 

Figures and Tables from this paper

Population and individual level of masting in a fleshy-fruited tree
TLDR
It is suggested that adverse weather conditions effectively limit fruit production, causing high inter-individual synchrony in low crop years, whereas the unsynchronized heavy crop years seem to have been affected by individually available resources.
Measuring mast seeding behavior: relationships among population variation, individual variation and synchrony.
Masting in Buxus balearica: assessing fruiting patterns and processes at a large spatial scale
TLDR
Experimental tests failed to support many of the results, namely a negative effect of previous reproduction on future flowering in island populations and lower pollen limitation with increasing flower production, and warn against exclusive reliance on correlations when testing hypotheses related to masting.
Patterns and mechanisms of masting in the large-seeded southern hemisphere conifer Araucaria araucana
TLDR
The existence of negative autocorrelation in seed production between year 0 and year -2 at the individual tree level suggests the presence of 'switching' or internal resource allocation, thus discarding the resource matching hypothesis.
The effect of within-year variation in acorn crop size on seed harvesting by avian hoarders
TLDR
These findings provide support for a mechanistic link between seed production and foraging behavior of seed dispersers as predicted by the predator dispersal hypothesis for the functional consequences of variable seed production in hoarder-dispersed trees.
Masting promotes individual- and population-level reproduction by increasing pollination efficiency.
TLDR
Parallel results at the population and individual tree level provide robust evidence for the ecological and potentially also evolutionary benefits of masting through increased pollination efficiency in ponderosa pine.
Why Is Seed Production So Variable among Individuals? A Ten-Year Study with Oaks Reveals the Importance of Soil Environment
TLDR
Individual seed production is strongly dependent on soil resource heterogeneity (at least for one of the two studied oak species) with potential repercussions for recruitment and population dynamics, although other external factors or certain inherent characteristics of the tree might be also involved in this process.
Does masting scale with plant size? High reproductive variability and low synchrony in small and unproductive individuals.
TLDR
This study shows that within-species variation in masting patterns is correlated with variation in fecundity, which in turn is related to plant size, and plays a major role in determining the variability and synchrony of reproduction in plants.
Long-term individual-level variation of reproductive features in Sorbus aucuparia, a fleshy-fruited tree
TLDR
Synchrony and fluctuation in reproductive output was not associated in individual trees and the synchrony between individual fruiting patterns was markedly reduced during the second half of the study period.
Correlated seed failure as an environmental veto to synchronize reproduction of masting plants
TLDR
The environmental veto hypothesis is explored by extending the resource budget model of masting with correlated reproductive failure to simulate seeding dynamics, and it is shown that resource dynamics and reproduction failure can produce masting even in the absence of pollen coupling.

MASTING BY EIGHTEEN NEW ZEALAND PLANT SPECIES: THE ROLE OF TEMPERATURE AS A SYNCHRONIZING CUE
TLDR
High intra- and intergeneric synchrony is demonstrated in mast seeding by 17 species of New Zealand plants from four families across >150 000 km2, and synchronous fruiting by these species was associated with anomalously high temperatures the summer before seedfall, a cue linked with the La Nina phase of ...
Annual Variability in Seed Production by Woody Plants and the Masting Concept: Reassessment of Principles and Relationship to Pollination and Seed Dispersal
TLDR
It is concluded that there are no objective reasons to perpetuate the concept of mast fruiting in the ecological literature as a shorthand to designate a distinct biological phenomenon and associations between supra‐annual variabiity in seed output and pollination and seed dispersal methods suggest the existence of important reproductive correlates that demand further investigation.
The evolutionary ecology of mast seeding in trees
TLDR
A positive relationship between the strength of the masts habit and the maxintum observed pre-dispersal seed mortality in a sample of 15 tree species suggests that the masting habit is best developed in predator-prone species.
MAST SEEDING IN PERENNIAL PLANTS: Why, How, Where?
TLDR
A survey of 570 masting datasets shows that wind-pollinated species had higher seed production coefficients of variation (CVs) than biotically pollinated ones, consistent with gaining benefits from predator satiation rather than dispersal.
VERTEBRATE RESPONSES TO SPATIOTEMPORAL VARIATION IN SEED PRODUCTION OF MAST-FRUITING DIPTEROCARPACEAE
TLDR
Results from this natural experiment indicate that resident and nomadic vertebrates cause stabilizing selection for tight interspecific synchrony of dipterocarp seedfall over vast regions.
Seed predation and cross-pollination in mast-seeding beech (Fagus sylvatica) patches
TLDR
Cross-pollination and seed predation may have been important factors in the evolution of mast seeding in beech and was negatively correlated with stand size.

TLDR
In this discussion of the escape of the offspring of a large sessile organism from predators and parasites, Leguminosae (the bean family) and the bruchid beetles that attack their seeds are used as an empirical example.
The Advantage of Mast Years for Wind Pollination
TLDR
The difference in the application of the model and two of its assumptions to these two major forest biomes is indicative of a fundamental difference in their strategies of pollination.
Scale of mast-seeding and tree-ring growth
TLDR
Synchrony in growth and reproduction, both within and among genera of Northern Hemisphere boreal trees, is detected across geographical areas almost the size of a continent, suggesting that mast-seeding is an evolved strategy that occurs on a geographic scale far larger than previously suspected.
