Significance Physiological decline in large, old trees could involve diminished reproductive effort, but evidence is lacking. A global analysis finds that fecundity large pervasive, consistent with physiological decline, thus providing new for tree senescence. For the 20% of species not showing declines, this lack was linked to specific groups, rather data. Large remain important their structural attributes, results highlight critical role intermediate contribution reproduction.
Abstract The relationships that control seed production in trees are fundamental to understanding the evolution of forest species and their capacity recover from increasing losses drought, fire, harvest. A synthesis fecundity data 714 worldwide allowed us examine hypotheses central quantifying reproduction, a foundation for assessing fitness trees. Four major findings emerged. First, is not constrained by strict trade-off between size numbers. Instead, numbers vary over ten orders magnitude,...
Climate change is impacting forests in complex ways, with indirect effects arising from interactions between tree growth and reproduction often overlooked. Our 43-y study of European beech ( Fagus sylvatica ) showed that rising summer temperatures since 2005 have led to more frequent seed production events. This shift increases reproductive effort but depletes the trees’ stored resources due insufficient recovery periods crops. Consequently, annual ring increments declined by 28%, dropping a...
Abstract Climate is one of the main factors driving species distributions and global biodiversity patterns. Obtaining accurate predictions species’ range shifts in response to ongoing climate change has thus become a key issue ecology conservation. Correlative distribution models ( cSDM s) have prominent tool this aim last decade demonstrated good predictive abilities with current conditions, irrespective studied taxon. However, s rely on statistical association between presence...
Masting, a variable and synchronized variation in reproductive effort is prevalent strategy among perennial plants, but the factors leading to interspecific differences masting remain unclear. Here, we investigate interannual patterns of investment 517 species terrestrial including herbs, graminoids, shrubs, trees. We place these context plants' phylogeny, habitat, form function. Our findings reveal that widespread across plant phylogeny. Nonetheless, reversion from regular seed production...
Summary Interannual variability of seed production, known as masting, has far‐reaching ecological impacts including effects on forest regeneration and the population dynamics consumers. Because relative timing management conservation efforts in ecosystems dominated by masting species often determines their success, there is a need to study mechanisms develop forecasting tools for production. Here, we aim establish production new branch discipline. We evaluate predictive capabilities three...
Abstract Aim Our understanding of the mechanisms that maintain forest diversity under changing climate can benefit from knowledge about traits are closely linked to fitness. We tested whether link between and seed number size is consistent with two hypotheses, termed leaf economics spectrum plant syndrome, or reproduction represents an independent dimension related a size–seed trade‐off. Location Most data come Europe, North Central America East Asia. A minority South America, Africa...
Biodiversity loss demands urgent action, and protected area are one of the cornerstone biodiversity conservation measure. While efforts known to be driven by economic political factors, there is an absence literature addressing potential role played behavioural traits at population level. We investigated how population-level influence proportion terrestrial using large-scale cross-cultural surveys geospatial data from 75 countries. show that explain more variation in coverage than indicators...
Spatial synchrony may be tail-dependent, meaning it is stronger for peaks rather than troughs, or vice versa. High interannual variation in seed production perennial plants, called masting, can synchronized at subcontinental scales, triggering extensive resource pulses famines. We used data from 99 populations of European beech (Fagus sylvatica) to examine whether masting differs between mast and years scarcity. Our results revealed that scarcity occurs simultaneously across the majority...
The impacts of climate change and anthropogenic disturbance are increasingly evident in the structure demographics tropical forests, yet response tree reproduction remains poorly understood. As fruit seed production is first step forest recruitment, this gap critical to understanding resilience. Tropical fruits important diets numerous frugivores essential resources for local human communities, thus changes quantity composition could have cascading effects on ecosystems people who depend...
Summary The periodic production of large seed crops, or masting, is a widespread phenomenon in perennial plants. This behavior can enhance the reproductive efficiency plants, leading to increased fitness, and produce ripple effects on food webs. While variability from year defining characteristic methods used quantify this are highly debated. commonly coefficient variation lacks ability account for serial dependence mast data be influenced by zeros, making it less suitable choice various...
Key message Phenology is of increasing interest to climate change science and adaptation ecology. Here, we provide bud development, leafing, leaf senescence data, collected on 772 European beech silver fir trees between 2006 2019 Mont Ventoux, France. Dataset access at https://doi.org/10.15454/TRFMZN . Associated metadata are available https://metadata-afs.nancy.inra.fr/geonetwork/srv/fre/catalog.search#/metadata/a33c8375-9a90-4bc3-a0d7-19317160b68f
