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‐

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 ...

Sustaining Science Infrastructure Is Difficult; Is Commercialization the Answer? The USA National Phenology Network's Experience

Perspectives of Earth and Space Scientists
Biological and physical science infrastructure programs play a critical role in supporting scientific discovery. Even with their foundational roles in the process of science, frequently, support for these programs is threatened, reduced, or eliminated ...

Global Assessment of Cumulative and Time-Lag Effects of Drought on Land Surface Phenology

GIScience & Remote Sensing, 2022
Increased frequency and intensity of droughts under climate change will have a significant impact on land surface phenology, however, the drought-phenology interactions that are associated with complex temporal effects are not well understood. This study

The mechanisms of phenology: the patterns and processes of phenological shifts

Ecological Monographs, 2018
AbstractSpecies across a wide range of taxa and habitats are shifting phenological events in response to climate change. While advances are common, shifts vary in magnitude and direction within and among species, and the basis for this variation is relatively unknown. We examine previously suggested patterns of variation in phenological shifts in order

Dental anomalies in Pleistocene African hippopotamuses from Olduvai Bed II

The Anatomical Record, EarlyView.
Abstract Hippopotamuses are key palaeoenvironmental indicators in African Pleistocene ecosystems due to their ecological dependence on permanent water bodies and their frequent representation in the fossil record. This study examines dental anomalies in Hippopotamus cf. gorgops from several localities in Bed II of Olduvai Gorge (Tanzania), dated to ca.

Larval phenology of Hemigrapsus sanguineus, an invasive species

, 2020
We modelled the larval phenology of the invasive crab Hemigrapsus sanguineus along the Atlantic coast of North America and North Europe. The phenology was computed from laboratory data on survival and duration of larval development, temperature and ...

Hyperspectral Applications to Landscape Phenology

, 2022
Phenology is the study of annual recurring biological life cycle events and the drivers and controls of their periodicity. Shifts in phenology depict a plant's integrated response to climate and environmental changes and have become an important source ...
