Abstract Masting of rowan Sorbus aucuparia L. has been studied in 45 sites in southern Norway for 22 years. We present data on the year-to-year variation in fruit setting of rowan, and show that masting is spatially synchronous in Norway and probably all over Fennoscandia. The apple fruit moth Argyresthia conjugella Zeller is an important seed predator on rowan. We present data on the abundance of apple fruit moth in rowanberries during these years and discuss the consequences of masting and… 

Masting and trophic cascades: interplay between rowan trees, apple fruit moth, and their parasitoid in southern Norway

Results show that rowan masting has an adaptive foundation, which impacts the dynamics of higher trophic levels, and two different components to the predator satiation, functional and numerical satiations are assessed, based on a simple population dynamics model.

Discrepancy in laboratory and field attraction of apple fruit moth Argyresthia conjugella to host plant volatiles

Attraction to synthetic compounds identified from rowan, anethole and 2‐phenyl ethanol confirms the role of plant volatiles in host finding and demonstrates that interaction with the background odour contributes to the behavioural effect of plant volatile stimuli in the field.

Attractive plant volatiles as a control method agai nst apple fruit moth ( Argyresthia conjugella Zell . ) ? Title German

Apple fruit moth, Argyresthia conjugella Zell. (Lepidoptera: Argyresthiidae), is the most important pest of apples in Scandinavia. In years when its primary host, rowan (Sorbus aucuparia L.), has

When does the apple fruit moth (Argyresthia conjugella) fly and oviposit?

The goal of this study was to examine the diel periodicity of male attraction to sex pheromone, and female oviposition behaviour under varying meteorological conditions.

Ground-living predators of the apple fruit moth Argyresthia conjugella (Zell.)

Large insects between 5 to 11 mm, were the major predator of the apple fruit moth, while the smaller insects of sizes 0-5 mm, dominated the predation during winter.

First host record of Argyresthia assimilis Moriuti, 1977 (Lepidoptera: Yponomeutidae) and a description of its annual life history

This tight synchronization between insect and host plant life histories suggests that the host range of A. assimilis is restricted to P. glabra and its close relatives.

Plant volatiles mediate attraction to host and non‐host plant in apple fruit moth, Argyresthia conjugella

Results confirm that volatiles common to both plants may account for a host switch in A. conjugella from rowan to apple, and support the idea that the odour signal from apple is suboptimal for attraction of A. Conjugella, but is nonetheless sufficient for attraction, during times when rowan is not available for egg laying.

Masting in Buxus balearica: assessing fruiting patterns and processes at a large spatial scale

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.



Fruit production in Sorbus aucuparia L. (Rosaceae) and pre-dispersal seed predation by the apple fruit moth (Argyresthia conjugella Zell.)

Differences in attraction of the seed predator to differences in fruit crop size could explain the observed difference in seed predation between the two populations with opposite fruiting patterns.

Ecology of mast-fruiting in three species of North American deciduous oaks.

The patterns of acorn production for black oak, red oak, and white oak are not simply responses to weather events but are also a function of prior reproductive events, which suggests that masting is an evolved reproductive strategy.

Cyclic population fluctuations of herbivores as an effect of cyclic seed cropping of plants: the mast depression hypothesis

The synchronised flowering cycles of plants indicate that high seed crops are induced by some climatic conditions, and allocating a large proportion of available resources to seed production in some years of advantageous conditions may improve a plant's total life-time reproduction, despite the subsequent risk of serious damage by herbivores.

Long-term variation in, and effects of fertiliser addition on, flower, fruit and seed production in the tree Sorbus aucuparia (Rosaceae)

In this paper, I present long-term data on reproduction for the tree Sorbus aucuparia. Variation in fruit-set (6 yr) in 22 trees in one population is described and related to flower predation,

Yield variations of some common wild berries in Finland in 1956-1996

Estimates of some of the most common wild berry abundances and changes in their yields compared with the previous year were made in 1956–1996 as a part of the annual autumn game inquiries. The

How Does Masting Happen and Synchronize

The present model suggests that masting can take place due to the resource balance of each plant even without any interannual environmental fluctuations, and may result in evolutionary benefits to each individual.

Induced Responses to Herbivory

This comprehensive evaluation and synthesis of a rapidly-developing field provides state-of-the-discipline reviews, and highlights areas of research which might be productive, should appeal to a wide variety of theoretical and applied researchers.

What causes outbreaks of the gypsy moth in North America?

This multitrophic relationship among mast, predators, and gypsy moths represents a very different explanation of forest insect outbreak dynamics than the more widely applied theories based upon predator–prey cycles or feedbacks with host foliage quality.

Scale of mast-seeding and tree-ring growth

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.
