Palatability of geophyte underground storage organs partially explains their depth in the Cape Floristic Region, geophyte capital of the world

American Journal of Botany, EarlyView.
Abstract Premise The soil depth of underground storage organs (USOs) of geophytes involves cost–benefit trade‐offs and may relate to USO age, size, and disturbances such as fire and herbivory. Yet determinants of USO depth are poorly studied. We posit that belowground mammalian predation of USOs is a selective force for the positive relationship ...

Earlier flowering did not alter pollen limitation in an early flowering shrub under short-term experimental warming

Scientific Reports, 2017
In animal pollinated plants, phenological shifts caused by climate change may have important ecological consequences. However, no empirical evidence exists at present on the consequences that flowering phenology shifts have on the strength of pollen ...

Turning a new leaf: PhenoVision provides leaf phenology data at the global scale

Applications in Plant Sciences, EarlyView.
Abstract Premise Plant phenology dictates many aspects of community function and ecosystem dynamics. Yet, global phenology data are still limited, especially in areas lacking monitoring programs. Here we present a new data resource, PhenoVision–Leaf, which extends a computer vision pipeline utilizing iNaturalist digital image vouchers to produce global‐

VASCULAR EPIPHYTES: THE UGLY DUCKLING OF PHENOLOGICAL STUDIES

Acta Biológica Colombiana, 2021
The phenology of vascular epiphytes, which represent account for about 10 % of the world’s flowering plants and perform important ecological functions, has been just partially explored. Since phenology is a key tool for the management and conservation of

Mining buried plant trait data from the Global Biodiversity Information Facility (GBIF): Comparison and integration with multiple plant trait databases

Applications in Plant Sciences, EarlyView.
Abstract Premise Despite the availability of several plant trait databases, significant traits remain undocumented for a substantial number of species. To address this issue, the current study explored digital text from the Global Biodiversity Information Facility (GBIF) as an innovative source of plant trait information and evaluated its capacity to ...

The evolution of flower size and flowering behaviour in plants: The role of pollination and pre-dispersal seed predation

, 2008
This thesis describes research into the effects of insect mediated pollination, and pre-dispersal seed predation, in common species of Asteraceae, varying both between and throughout growing seasons, and suggests that these exert selective pressures ...

Predicting spring migration of two European amphibian species with plant phenology using citizen science data

Scientific Reports, 2021
Habitat fragmentation is one of the drivers for amphibian population declines globally. Especially in industrialized countries roads disrupt the seasonal migration of amphibians between hibernation and reproduction sites, often ending in roadkills. Thus,

Petal to the metal: The slow road to automating large‐scale phenology labeling for herbarium specimens

Applications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens represent critical historical records of plant phenology, yet automating annotation of reproductive structures remains challenging given the diversity of floral morphologies, specimen age and quality, and image quality.

A review of remote sensing applications in flower phenology detection

Journal of Ecology and Environment
The shift in flowering phenology with plants blooming earlier due to climate change, disrupts the synchronization between plants and pollinators by creating temporal and spatial mismatches.
