Climate-influenced ponderosa pine (Pinus ponderosa) seed masting trends in western Montana, USA

open access: yesForest Systems, 2015
Aim of study: The aim of this study was to analyze 10-year records of ponderosa pine (Pinus ponderosa) seed production, in order to confirm synchronic seed production and to evaluate cyclical masting trends, masting depletion effect, and climate-masting ...

Modeling the impact of reproductive mode on masting

open access: yes, 2017
: Masting is defined as the intermittent highly variable production of seed in a plant population. According to reproductive modes, that is, sexual and asexual reproduction, masting species can be separated into three groups, that is, (1) species, for ...

Temperature cues and molecular control of masting. [PDF]

open access: yes, 2019
Mast flowering (masting) is synchronised highly variable flowering by a population of perennial plants over a wide geographical area. Masting causes widespread community effects, including in New Zealand negative impacts on threatened birds, therefore ...

Masts and towers

open access: yes, 2010
The analysis and design of masts and towers requires special knowledge and experience, especially when it concerns guyed masts. The special problems related to these structures are underlined by the many collapses during the years. The basis of design for such antenna supporting structures are sometimes many and often mutual contradictory, and the ...

Beech tree masting explains the inter-annual variation in the fall and spring peaks of Ixodes ricinus ticks with different time lags

open access: yesParasites & Vectors, 2021
Background The tick Ixodes ricinus is an important vector of tick-borne diseases including Lyme borreliosis. In continental Europe, the nymphal stage of I. ricinus often has a bimodal phenology with a large spring peak and a smaller fall peak.

An increase in canopy cover leads to masting in Quercusilex

open access: yes, 2010
10 páginas, 6 figuras, 4 tablas.Masting is the intermittent and synchronous production of large crops, but its relation to tree growth remains elusive despite the ecological relevance of mast seeding. The production of huge fruit crops has been linked to

Intrinsic biotic factors and microsite conditions drive seedling survival in a species with masting reproduction

open access: yesEcology and Evolution, 2019
Seedling recruitment following a masting event, where more fruits are produced in synchrony and intermittently compared with other species, plays a crucial role in determining species diversity and community structure.

Mast cells and canine mast cell tumours. A review [PDF]

open access: yesVeterinary Quarterly, 2004
This article reviews the literature on mast cells and tumours derived from mast cells in the dog. Mast cells play a central role in inflammatory and immune reactions. Mast cells, normal and neoplastic, contain and release important biologically active substances: heparin, histamine, eosinophilic chemotactic factor and proteolytic enzymes.

Oak masting drivers vary between populations depending on their climatic environments

open access: yes, 2023
Large interannual variation in seed production, called masting, is very common in wind-pollinated tree populations and has profound implications for the dynamics of forest ecosystems and the epidemiology of certain human diseases. 1 ,2 ,3 ,4 ,5 Comparing
