The evolutionary ecology of mast seeding
Trends in Ecology & Evolution, 1994The past seven years have seen a revolution in understanding the causes of mast seeding In perennial plants. Before 1987, the two main theories were resource matching (i.e. plants vary their reproductive output to match variable resources) and predator satiation (i.e. losses to predators are reduced by varying the seed crop).

The Janzen–Connell hypothesis and seed masting
Trends in Ecology & EvolutionThe Janzen-Connell hypothesis (JC effect) has been proposed as a mechanism for explaining high tropical tree diversity via negative conspecific density dependence imposed by natural enemies. Seed masting describes the uneven investment in reproduction between years, and could be a mechanism for reducing seed predation by means of predator satiation. JC

AbstractTemporal autocorrelation in environmental conditions influences population dynamics through its effects on vital rates. However, a comprehensive understanding of how and to what extent temporal autocorrelation shapes population dynamics is still lacking because most empirical studies have unrealistically assumed that environmental conditions ...

Cephalotaxine homologous alkaloids from seeds of Cephalotaxus oliveri Mast
Phytochemistry, 2022Six undescribed isoquinoline alkaloids, named as cephaloliverines A-F, were isolated from the seeds of Cephalotaxus oliveri. They were identified by NMR and MS spectroscopic data analyses, combined with the time-dependent density functional theory ECD calculation for cephaloliverines A and B and also by X-ray crystal diffraction for cephaloliverine E ...

Resource depletion, pollen coupling, and the ecology of mast seeding
Annals of the New York Academy of Sciences, 2014Masting, the highly variable and synchronous production of seeds across a population of perennial plants, is an ecologically important, but still poorly understood, phenomenon. While much is known about the fitness benefits of masting and its effects on seed consumers and trophic interactions, less is understood about the proximate mechanisms of ...

Seed masting as a mechanism for escape from pathogens
Current BiologySeed masting, a reproductive strategy characterized by variable and synchronous investment in reproduction among years, has attracted much attention. Masting trees incur a cost in delayed reproduction, and thus masting requires an ecological or evolutionary explanation.

[A review on mast seeding studies].
Ying yong sheng tai xue bao = The journal of applied ecology, 2003Mast seeding means that the plants of a population have a highly variable seed production in different years synchronously, and it is widely existed in perennial plants. The periodic variation of seed yield and synchrony of seed production among individuals are the key characteristics. Several hypotheses, including evolutionary bases and limitations of

SEED MASS AND MAST SEEDING ENHANCE DISPERSAL BY A NEOTROPICAL SCATTER‐HOARDING RODENT
Ecological Monographs, 2004Many tree species that depend on scatter‐hoarding animals for seed dispersal produce massive crops of large seeds at irregular intervals. Mast seeding and large seed size in these species have been explained as adaptations to increase animal dispersal and reduce predation.

Seed size and dispersal mode select mast seeding in perennial plants
Integrative ZoologyAbstractReproduction by perennial plants varies from being relatively constant over years to the production of massive and synchronous seed crops at irregular intervals, a reproductive strategy called mast seeding. The sources of interspecific differences in the extent of interannual variation in seed production are largely unknown.

The evolutionary ecology of mast seeding in trees
Biological Journal of the Linnean Society, 1980The hypothesis that masting by trees is a defensive strategy which satiates seed predators in mast years and starves them in the intervening periods is tested in 59 sets of data on the seed production and pre-dispersal seed-predation of 25 tree species. Twenty-lour of the 59 data-sets support the hypothesis and show a statistically significant positive
