Facilitative interspecific interactions in marine vertebrates across scales: from individuals to ecosystems. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT Facilitative interspecific interactions (FIIs) confer benefits to at least one participant without detriment to others. Although often less emphasised than antagonistic interactions in ecological studies, this review highlights the significant ecological role of FIIs across biological scales – from individual behaviours to population ...

Volcanic Diffuse Volatile Emissions Tracked by Plant Responses Detectable From Space

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Volcanic volatile emissions provide information about volcanic unrest but are difficult to detect with satellites. Volcanic degassing affects plants by elevating local CO2 and H2O concentrations, which may increase photosynthesis.

Emergence, spread, and impact of high-pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica. [PDF]

open access: yesConserv Biol
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Evaluating the efficacy of carbachol at reducing corvid predation on artificial nests

open access: yesWildlife Society Bulletin, 2018
Nest predation often limits recovery of threatened and endangered birds, especially ground‐nesting species. Accordingly, a variety of techniques are used to reduce the impact of nest predation on listed species.

Viscous fingering and dendritic growth under an elastic membrane [PDF]

open access: yes, 2016
We investigate the viscous fingering instability that arises when air is injected from the end of an oil-filled, compliant channel. We show that induced axial and transverse depth gradients foster novel pattern formation. Moreover, the steady propagation
