Evolution of masting in plants is linked to investment in low tissue mortality [PDF]
Nature Communications, 2023 Masting, a variable and synchronized variation in reproductive effort is a prevalent strategy among perennial plants, but the factors leading to interspecific differences in masting remain unclear.

Masting Breakdown in European Beech Reduces Fitness Benefits of Masting, Partly Explained by Climate Change [PDF]
Ecology and EvolutionMasting, highly synchronised but temporally variable seed production, is initiated by weather cues and is thus highly sensitive to climate change. Changes in these cues can lead to a masting breakdown, reducing the fitness benefits of masting through ...

Novel food resources and conservation of ecological interactions between the Andean Araucaria and the Austral parakeet [PDF]
Ecology and Evolution, 2022 In fragile ecosystems, the introduction of exotic species could alter some ecological processes. The Austral parakeet (Enicognathus ferrugineous) shows close ecological and evolutionary relationships with the Andean Araucaria (Araucaria araucana), so any

Brood size in an uncertain world [PDF]
Royal Society Open Science, 2023 Reproduction in an uncertain world is fraught. The consequences of investing in too many offspring in a resource poor season can be disastrous but so too is missing the opportunity of a resource rich year.

Flowering and Flower Maturation in Valley Oak Quercus lobata [PDF]
Ecology and EvolutionWe investigated factors driving flowering and flower maturation and their effects on acorn production at both the annual and individual trees levels in a population of valley oak (Quercus lobata) in central coastal California, USA.

Weather drivers of reproductive variability in perennial plants and their implications for climate change risks [PDF]
Nature CommunicationsSeed production in perennial plants often shows strong year-to-year variation, a phenomenon known as masting. Masting is typically adaptive and driven by weather cues that synchronize reproduction by promoting or suppressing flowering and seed set. These

Variable Breeding Strategies in a Fluctuating Environment: A Feeding Experiment in Eastern Chipmunks [PDF]
Ecology and EvolutionSmall mammals inhabiting pulsed‐resource environments, such as forests with intermittent seed masting of trees, often adjust their allocation to reproduction with the drastic fluctuations in food availability.

Correlation between airborne pollen data and the risk of tick-borne encephalitis in northern Italy [PDF]
Scientific Reports, 2023 Tick-borne encephalitis (TBE) is caused by a flavivirus that infects animals including humans. In Europe, the TBE virus circulates enzootically in natural foci among ticks and rodent hosts. The abundance of ticks depends on the abundance of rodent hosts,

Indications of an Achaea sp. caterpillar outbreak disrupting fruiting of an ectomycorrhizal tropical tree in Central African rainforest [PDF]
Plant Ecology and Evolution, 2023 Background and aims – Where one or several tree species come to dominate patches of tropical forest, as many masting ectomycorrhizal legumes do in Central Africa, ecological theory predicts they may be prone to herbivory, which might alter their ...
