Multifunctions of fine root phenology in vegetative and reproductive growth in mature beech forest ecosystems

open access: yesEcosphere, 2021
Masting, a large interannual variation of reproductive investment spatially synchronized within perennial plants, is an important factor for understanding the use and storage of carbon and nutrient resources in various forest ecosystems.

Climate warming causes mast seeding to break down by reducing sensitivity to weather cues [PDF]

open access: yes, 2021
Climate change is altering patterns of seed production worldwide with consequences for population recruitment and migration potential. For the many species that regenerate through synchronized, quasiperiodic reproductive events termed masting, these ...

Immigration drives ship rat population irruptions in marginal high‐elevation habitat in response to pulsed resources

open access: yesEcosphere, 2023
Pest animal populations, such as rodents, often irrupt in response to pulsed resources. However, few studies have considered how understanding the propagation of irruptions across landscapes could lead to more efficient pest suppression.

Dynamics of non-structural carbohydrates following a full masting event reveal a role for stored starch in relation to reproduction in Fagus crenata

open access: yesForestry Research, 2021
Although mature trees have substantial non-structural carbohydrate (NSC) storage that is well documented with respect to its capacity to buffer the asynchrony of supply and demand at the whole-plant level, its role in reproduction remains poorly ...

Role of phosphoinositide 3-kinases in mast cell activation [PDF]

open access: yes, 2009
Mast cells are primary effector cells in allergy and chronic inflammation. Class IB (PI3Kγ) and class IA (PI3Kδ) PI3K have been shown to play major roles in mast cell activation: antigen/IgE stimulation triggers autocrine/paracrine activation of mast ...

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.

MiR-146a: a key microRNA involved in regulating mast cell survival and T lymphocyte differentiation [PDF]

open access: yes, 2013
Mast cells are long-lived, tissue-resident cells of the innate immune system. Since the identification of mechanisms that regulate mast cell proliferation, survival and overall homeostasis in the tissues may have important implications for the treatment ...

SOLPS-ITER predictive simulations of the impact of ion-molecule elastic collisions on strongly detached MAST-U Super-X divertor conditions

open access: yesNuclear Fusion, 2023
The role of ion-molecule ( $D^+-D_2$ ) elastic collisions in strongly detached divertor conditions has been studied in the MAST-U Super-X configuration using SOLPS-ITER.

Masting effect on canopy greenness and climate response on seed production of Fagus grandifolia subsp. mexicana across the Sierra Madre Oriental, Mexico

open access: yesClimate Change Ecology, 2021
Specific proximate mechanisms as climate spatial fluctuations modify the pattern of synchronic reproduction (masting) or seed production at population level in the Fagus genus worldwide.
