Limnology and Oceanography: Methods, EarlyView.Abstract Recent technological advancements have rapidly expanded our capacity for collecting image data in the marine environment, but processing images into meaningful ecological metrics remains a manual, time‐consuming, and biased process. This is particularly challenging with electro‐optical cabled imaging systems which generate images at a rate ...

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To develop a robust deep learning framework for noncontrast‐enhanced functional lung MRI, overcoming the limitations of spectral decomposition in the presence of physiological nonstationarity. Methods We introduce VQ‐Wave (Ventilation/Q‐perfusion Waveform‐based Assessment of Variable Evolutions), a physics‐driven spatiotemporal ...

UAV photogrammetry for red tide monitoring and geo-localization via onboard GNSS/IMU data
Geocarto InternationalAs one of the worst ecological disasters in the world’s oceans, red tide seriously threatens marine ecology. Red tide monitoring is essential for preserving the ocean ecosystem. However, traditional photogrammetric processing workflows, e.g.

Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status
Nordic Journal of Botany, EarlyView.Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Taxonomic reappraisal of the mangrove genus Avicennia (Acanthaceae) in India
Nordic Journal of Botany, EarlyView.A taxonomic reappraisal of the mangrove genus Avicennia in India was undertaken through extensive field surveys and critical examination of herbarium specimens. Three taxa, Avicennia alba, Avicennia marina subsp. marina, and Avicennia officinalis, are described in detail. A synonymic list was compiled using the World Checklist of Vascular Plants (WCVP)

The effects of single versus successive warm summers on an intertidal community
Oikos, EarlyView.To accurately predict how organisms and ecological communities will respond to future conditions caused by climate change, we must consider the temporal dynamics of environmental stressors, including the effects of repeated exposures to stress. We performed a two‐year passive thermal manipulation in coastal British Columbia, Canada to determine how ...

Coexistence, crossover and extirpation in coalescent communities and ecotones
Oikos, EarlyView.When two ecological communities come into contact, the strength of their mixing determines whether species coexist, extirpate, or extend their ranges. We present analytical formulas and simulations describing these transitions. Specifically, we derive abundance shifts upon community coalescence, identify the critical mixing strength leading to first ...
