Reproductive phenology of Passiflora cincinnata Mast. in the semi-arid region of Bahia State, Brazil, based on herbarium data and IDW interpolation [PDF]

open access: yesHoehnea, 2023
We investigated intensity and seasonality of the reproductive phenology of Passiflora cincinnata Mast. and estimated its flowering and fruiting periods by interpolation using Inverse Distance Weighting, for the first time in phenology, based on herbarium

Pleiotropy of FRIGIDA enhances the potential for multivariate adaptation. [PDF]

open access: yes, 2013
An evolutionary response to selection requires genetic variation; however, even if it exists, then the genetic details of the variation can constrain adaptation.

Plasticity and not adaptation is the primary source of temperature-mediated variation in flowering phenology in North America

open access: yesNature Ecology & Evolution
Phenology varies widely over space and time because of its sensitivity to climate. However, whether phenological variation is primarily generated by rapid organismal responses (plasticity) or local adaptation remains unresolved.

Greater temperature sensitivity of plant phenology at colder sites: implications for convergence across northern latitudes [PDF]

open access: yes, 2017
Warmer temperatures are accelerating the phenology of organisms around the world. Temperature sensitivity of phenology might be greater in colder, higher latitude sites than in warmer regions, in part because small changes in temperature constitute ...

Tracing phenology of subarctic plant sover the last century [PDF]

open access: yesPolish Polar Research, 2018
Climate change has been affecting plants over the last century and caused changes in life history features such as the flowering time. Herbarium specimens provide a snapshot of the past environmental conditions during their collection.

Predators do not spill over from forest fragments to maize fields in a landscape mosaic in central Argentina [PDF]

open access: yes, 2017
South America is undergoing a rapid and large scale conversion of natural habitats to cultivated land. Ecosystem services (ESs) still remain important but their level and sustainability are not known.

Differences on flowering phenology under Mediterranean and Subtropical environments for two representative olive cultivars

open access: yes, 2020
Olive flowering phenology is highly affected by climatic conditions. Climatic models have been developed to forecast flowering date on olive mainly based on temperature.

Deep Learning and Phenology Enhance Large-Scale Tree Species Classification in Aerial Imagery during a Biosecurity Response

open access: yesRemote Sensing, 2021
The ability of deep convolutional neural networks (deep learning) to learn complex visual characteristics offers a new method to classify tree species using lower-cost data such as regional aerial RGB imagery.

Towards a unified characterization of phenological phases: fluctuations and correlations with temperature

open access: yes, 2010
Phenological timing -- i.e. the course of annually recurring development stages in nature -- is of particular interest since it can be understood as a proxy for the climate at a specific region; moreover changes in the so called phenological phases can ...

Changing Climate Drives Divergent and Nonlinear Shifts in Flowering Phenology across Elevations.

open access: yesCurrent Biology, 2019
Climate change is known to affect regional weather patterns and phenology; however, we lack understanding of how climate drives phenological change across local spatial gradients.
