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‐

Integrating machine learning, deep learning, and image analysis for seed species classification

Applications in Plant Sciences, EarlyView.
Abstract Premise The growing demand for wildflower seeds in ecological restoration requires reliable species identification, yet current market products often contain heterogeneous species. As seed identification is labor‐intensive and requires advanced botanical knowledge, we evaluated multiple segmentation and classification approaches to determine ...

Influence of Reproductive Status on Occupancy of Salvage‐Logged Boreal Forest by Moose (Alces americanus)

Ecology and Evolution
Wildlife‐habitat relationships reflect the behavioral choices made by species in response to perceived risks and rewards. Ungulates must often choose between habitats that provide forage and those offering concealment from predators, yet natural and ...

Molecular methods for differentiating Phragmites australis subspecies and identification of hybrid stands in the Upper Midwestern United States

Applications in Plant Sciences, EarlyView.
Abstract Premise In North America, Phragmites australis (common reed) has drawn a great deal of research attention. Non‐native P. australis subsp. australis is a noxious weed that has locally displaced native P. australis subsp. americanus in some areas.

Spatial organisation and feeding ecology of the American mink (Mustela vison) in a coastal habitat [PDF]

, 1996
The American mink (Mustela vison Schreber) is the only introduced carnivore that has successfully colonised the British Isles. In the present study, the important problem of understanding which are the factors that limit or enhance their number has been ...

Mapping Lupinus polyphyllus density and distribution along road verges using unmanned aerial vehicle (UAV)–based remote sensing

Applications in Plant Sciences, EarlyView.
Abstract Premise Road verges function as refuges for semi‐natural species, but they can also facilitate the spread of non‐native plants such as Lupinus polyphyllus. Unmanned aerial vehicle (UAV)–based remote sensing is a promising tool for mapping these species; however, its application in roadside contexts remains limited.

Trade‐offs in habitat use and occupancy of bats across the gradient of urbanization and seasons

Ecosphere
Urbanization that occurs across a gradient from low‐ to high‐density development, is a primary driver of landscape change that can affect biodiversity. Animals balance trade‐offs in obtaining resources and avoiding anthropogenic disturbances across the ...
