Combining multibeam and single beam echosounders for quantifying gas bubble release from the seafloor

Limnology and Oceanography: Methods, EarlyView.
Abstract Marine gas bubble release is a worldwide phenomenon that impacts the local marine ecosystem and contributes to carbon fluxes with respect to global warming. It is still challenging to assess gas flow for large seep areas (tens of km2), but recent advances in calibrating and processing multibeam echosounder (MBES) data make this problem ...

Emerging Urban Forests: Opportunities for Promoting the Wild Side of the Urban Green Infrastructure [PDF]

, 2019
Many cities aim to increase urban forest cover to benefit residents through the provision of ecosystem services and to promote biodiversity. As a complement to traditional forest plantings, we address opportunities associated with “emerging urban forests”

Relationships between acoustic scattering layers and ocean stratification: An acoustic approach to estimate mixed layer depth

Limnology and Oceanography: Methods, EarlyView.
Abstract Ocean stratification, measured as mixed layer depth (MLD), is an important feature that influences many processes in the ocean; for example, by mediating the fluxes of momentum, heat and crucially key gases such as CO2 and oxygen from the atmosphere into the water column and vice versa. The conventional methods to measure stratification (e.g.,

Wildlife-livestock interactions and risk areas for cross-species spread of bovine tuberculosis [PDF]

, 2017
The transmission of diseases between livestock and wildlife can be a hindrance to effective disease control. Maintenance hosts and contact rates should be explored to further understand the transmission dynamics at the wildlife-livestock interface ...

Two new records for the flora of Paraguay: Stemodia diplohyptoides and S. lobelioides (Plantaginaceae:Gratioleae)

Nordic Journal of Botany, EarlyView.
Stemodia diplohyptoides M.M.Sosa & Dematt. and S. lobelioides Lehm. (Gratioleae, Plantaginaceae) are reported for the first time in Paraguay, found in Alto Paraná and Presidente Hayes departments, respectively. These new records extend the known geographical range of both species, representing the northern records to date, S.

Integrating Research Data Management into Geographical Information Systems

, 2015
Ocean modelling requires the production of high-fidelity computational meshes upon which to solve the equations of motion. The production of such meshes by hand is often infeasible, considering the complexity of the bathymetry and coastlines.

Taxonomic treatment, geographic distribution and preliminar conservation status of Croton sect. Barhamia subsect. Barhamia (Euphorbiaceae) in Brazil

Nordic Journal of Botany, EarlyView.
The genus Croton (Euphorbiaceae) is an exceptionally megadiverse genus, encompassing roughly 1200 species that are predominantly distributed across tropical regions globally. For the New World, the genus is organized into three subgenera (Adenophylli, Geiseleria and Quadrilobi) and 31 sections, with C. sect. Barhamia standing out with its approximately
