The mast cell and mast cell disease

open access: yesJournal of the American Academy of Dermatology, 1995
Mast cell disease or mastocytosis is a heterogeneous group of clinical disorders characterized by the proliferation and accumulation of mast cells in a variety of tissues, most often the skin. The signs and symptoms of mast cell disease are varied, dependent on the localization of mast cells in different organs and the local and systemic effects of ...

The Percentage of Trees Bearing Cones as a Predictor for Annual Longleaf Pine Cone Production

open access: yesFrontiers in Forests and Global Change, 2021
The U.S. Forest Service has monitored longleaf pine cone production at sites throughout the southeastern United States for over 60 years. Data from the multi-decadal surveys have supported our understanding of the variability of stand-level cone ...

Resource pulses and human–wildlife conflicts: linking satellite indicators and ground data on forest productivity to predict brown bear damages

open access: yesRemote Sensing in Ecology and Conservation, 2023
Pulsed resources have prominent effects on community and ecosystem dynamics; however, there is little research on how resource pulses affect human–wildlife interactions.

Leaf defoliation and Tabernaemontana rotensis (Asterids: Gentianales: Apocynaceae) flower induction and fruit development

open access: yesJournal of Threatened Taxa, 2023
Tabernaemontana rotensis (Kaneh.) P.T. Li is an attractive small tree that is endemic to the islands of Guam and Rota. Conservation efforts of the threatened population are constrained by lack of research.

Seed masting is stronger in tall plants

open access: yes, 2023
Two economies of scale, predator satiation and pollination efficiency, have been proposed to explain the evolutionary mechanisms of seed masting adopted by some long-lived plants. Plant height is strongly selected by pollination vectors and therefore may

Differential spatial responses of rodents to masting on forest sites with differing disturbance history

open access: yesEcology and Evolution, 2021
Mast seeding, the synchronized interannual variation in seed production of trees, is a well‐known bottom‐up driver for population densities of granivorous forest rodents.

Detection of Southern Beech Heavy Flowering Using Sentinel-2 Imagery

open access: yesRemote Sensing, 2022
The southern beech (genus Fuscospora and Lophozonia) forest in New Zealand periodically has “mast” years, during which very large volumes of seeds are produced.

Effect of tree age on masting signal in tree-ring chronologies of beech in southern Sweden [PDF]

open access: yes, 2023
Masting is a synchronous and highly variable production of seeds in tree species. Masting may reflect a reproduction strategy to cope with seed predation. In beech, temperature is the cue controlling annual variability in seeding. Masting behaviour in

Nature beyond Linearity: Meteorological Variability and Jensen's Inequality Can Explain Mast Seeding Behavior

open access: yesFrontiers in Ecology and Evolution, 2017
Mast seeding, the extremely variable and synchronized production of fruits, is a common reproductive behavior in plants. Weather is centrally involved in driving masting.
