Saussurea × media (Asteraceae), a new natural hybrid between S. parviflora and S. controversa

open access: yesNordic Journal of Botany, EarlyView.
Saussurea × media Yusupovsky and E.Pjak (Asteraceae), a new nothospecies from the Altai‐Sayan Mountains, is described and illustrated. In this study, we sequenced the internal transcribed spacer of nuclear ribosomal DNA and the chloroplast intergenic spacers rsp16‐trnQ and ycf4‐cemA to verify the hypothesis of hybridization between Saussurea parviflora

Interactive Effects of Arbuscular Mycorrhizal Fungi and Copper Stress on Flowering Phenology and Reproduction of Elsholtzia splendens.

open access: yesPLoS ONE, 2015
Plant responses to heavy metal contamination may depend on the presence of arbuscular mycorrhizal fungi (AMF). Elsholtzia splendens is an indicator species for the presence of copper (Cu) mines because both its flowering phenology and reproduction are ...

Long‐term trends in global flowering phenology

open access: yesNew Phytologist
Summary Flowering phenology is an indicator of the impact of climate change on natural systems. Anthropogenic climate change has progressed over more than two centuries, but ecological studies are mostly short in comparison.

Measuring Flowering Phenology and its Consequences: A Systematic Review [PDF]

open access: yes, 2019
Despite growing interest in flowering phenology among ecologists, as reflected by an increase in the number of papers, there is little information on how studies typically measure and describe a plant’s flowering phenology.

Do good neighbours compensate for bad climate? The case of sessile oak Quercus petraea in phylogenetically distant neighbourhoods

open access: yesOikos, EarlyView.
Stressful climates threaten the performance of individuals and the survival of species, but individual performance also depends on biotic interactions with neighbours, so that ‘good' neighbours might in theory compensate for ‘bad' climates. However, what makes a good neighbour, and why, has been little studied.

Predicting flowering phenology in a subarctic plant community

open access: yes, 2014
Phenological studies are rarely reported from arctic and subarctic regions, but are essential to evaluate species' response to climate change in these rapidly warming ecosystems.

Yearly fluctuations of flower landscape in a Mediterranean scrubland: Consequences for floral resource availability.

open access: yesPLoS ONE, 2018
Species flower production and flowering phenology vary from year to year due to extrinsic factors. Inter-annual variability in flowering patterns may have important consequences for attractiveness to pollinators, and ultimately, plant reproductive output.

Flower power: tree flowering phenology as a settlement cue for migrating birds

open access: yesJournal of Animal Ecology, 2008
1. Neotropical migrant birds show a clear preference for stopover habitats with ample food supplies; yet, the proximate cues underlying these decisions remain unclear. 2. For insectivorous migrants, cues associated with vegetative phenology (e.g. flowering, leaf flush, and leaf loss) may reliably predict the availability of herbivorous arthropods. Here

Remote sensing and citizen science for habitat mapping: A machine learning approach to lowland heathland in Surrey, UK

open access: yesPeople and Nature, EarlyView.
Abstract In a time of extensive global biodiversity loss, conservation efforts increasingly rely on high‐resolution, accurate, up‐to‐date habitat maps to guide decision‐making and strategic interventions. Many products have been developed in response, using machine learning (ML) methods to automate habitat classification, often relying on satellite ...

Reshaping phenology: Grazing has stronger effects than climate on flowering and fruiting phenology in desert plants

open access: yes, 2020
Resources and climatic conditions impose bottom-up selective forces on flowering phenology, enabling flowering to occur when climatic conditions are the most suitable for reproduction.
