The Mid-Domain Effect Shapes a Unimodal Latitudinal Pattern in Fruiting Phenology [PDF]

open access: yesPlants
The mid-domain effect (MDE) has been used to explain spatial diversity patterns and flowering phenology, but its role in fruiting phenology has received limited attention to date.

Phenological patterns of herbaceous Mediterranean plant communities in spring: is there a difference between native and formerly-cultivated grasslands? [PDF]

open access: yesPlant Ecology and Evolution, 2022
Background and aims – Plant phenology, defined as the timing of recurring life events like leaf flushing, flowering, or fruiting, is highly sensitive to environmental factors such as photoperiod, temperature, and moisture.

Estimating phenology and phenological shifts with hierarchical modeling

open access: yesEcology, 2023
AbstractClimate‐driven changes to phenology are some of the most prevalent climate change impacts, yet there is no commonly accepted approach to modeling phenological shifts. Here, we present a hierarchical modeling framework for estimating intra‐annual patterns in phenology (e.g., peak phenological expression) and analyzing interannual rates of change

The USA National Phenology Network's Buffelgrass Green‐up Forecast map products

open access: yesEcological Solutions and Evidence, 2021
Buffelgrass (Cenchrus ciliaris syn. Pennisetum ciliare) was introduced to Sonoran Desert in the early 20th century and has become widespread at low elevations. This perennial bunchgrass accumulates abundant biomass that can carry fires through ecosystems

A dataset of Neotropical liana research focusing on the strategies of control for forest restoration and management practices

open access: yesAnnals of Forest Science, 2022
Key message Forest fragmentation leads to a micro-environmental condition that favors the proliferation of liana, which infest trees, compete with them, and reduce their performance.
