Evaluating the Wind Pollination Benefits of Mast Seeding

Ecology, 2001
We developed a conceptual model for evaluating the benefits of wind pollination to mast-flowering species. The benefit that a plant population gains from mast flowering via increased wind pollination efficiency was predicted from how far pollination efficiency at mean seed crop size falls below the maximum. Species were most likely to benefit from mast

Amplified Cyclicality in Mast Seeding Dynamics Positively Influences the Dynamics of a Seed Consumer Species

open access: yesThe American Naturalist, 2023
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 ...

The mast seeding plants of Bhutan [PDF]

open access: yes, 2014
Mast seeding, the intermittent production of synchronized seed crops among plant populations, is a world-wide phenomenon that has been reported in the Himalayan mountains across a large number of habitat types, and among a wide variety of long-lived grass, shrub and tree species. In this paper, we review various hypotheses that explain why mast seeding

Mast seeding and Lyme disease

Trends in Ecology & Evolution, 1998
In her cogent review of the factors controlling levels of Lyme disease, Randolph[1xRandolph, S.E. Trends Ecol. Evol. 1998; 13: 301–303Abstract | Full Text | Full Text PDF | PubMed | Scopus (7)See all References][1]makes one small error. She shows that `mast years' (high acorn crops) are associated with outbreaks of mice, with variable effects on ...

Mast seeding patterns are asynchronous at a continental scale

Nature Plants, 2020
Resource pulses are rare events with a short duration and high magnitude that drive the dynamics of both plant and animal populations and communities1. Mast seeding is perhaps the most common type of resource pulse that occurs in terrestrial ecosystems2, is characterized by the synchronous and highly variable production of seed crops by a population of

Masting, seed dispersal and seed predation in the cycad Macrozamia communis

Oecologia, 1986
Little is known about the adaptive value of mast seeding, a common phenomenon in temperate trees and shrubs. Masting is likely to affect both seed dispersal and seed predation. In systems where similar taxa of animals are involved in these two processes, the consequences of mast seeding are likely to be particularly complicated. This study examined the

Coevolution of mast seeding in trees and extended diapause of seed predators

Journal of Theoretical Biology, 2013
Many trees in forests show synchronized and intermittent reproduction, which is called "masting" or mast seeding. According to recent theoretical studies, the evolution of masting is promoted both by recruitment through the seedling bank and by seed predators.

The evolutionary ecology of mast seeding

Trends in Ecology & Evolution, 1994
The 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).
