Tide distortion and attenuation in an Amazonian tidal river

open access: yesBrazilian Journal of Oceanography, 2012
The present study seeks to evaluate tidal propagation in the Guamá-Capim river system, in the Amazonian region, considering hydrodynamic and geomorphological aspects.

Turbulence measurements in the Garonne River tidal bore: First observations

open access: yes, 2011
A tidal bore is an abrupt rise in water depth advancing in some estuaries during spring tide conditions. In the present study, some detailed turbulence field measurements were conducted continuously at high-frequency (64 Hz) in the Garonne River tidal ...

Age, growth and sexual dimorphism of the monkeyface prickleback (Cebidichthys violaceus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Accurate estimates of age, growth and maturation are fundamental to fisheries assessment, conservation and the development of emerging aquaculture species. However, life‐history parameters can vary within species and may be influenced by factors such as sexual dimorphism, which is often poorly quantified in non‐commercial or understudied ...

Environmental Impact of a Tidal Bore on Tropical Rivers [PDF]

open access: yes, 2002
A tidal bore impacts significantly on the estuarine ecosystem, although little is known on the flow field, mixing and sediment motion beneath tidal bores.

Spot the difference: Turbidity‐driven plasticity and variation in spotted grunter (Pomadasys commersonnii) spot patterns

open access: yesJournal of Fish Biology, EarlyView.
Abstract Animal body markings such as spots, stripes and patterns play important roles in camouflage and visual communication. This study investigated phenotypic plasticity in the spot patterns of spotted grunter Pomadasys commersonnii, an estuarine‐dependent haemulid species.

Reimagining Interdisciplinarity: Sensitization, Reflexivity, and Mobilization Across Landscapes of Practice

open access: yesJournal of Management Studies, EarlyView.
Abstract Interdisciplinary research (IDR) is widely promoted as essential for addressing complex societal challenges, yet its enactment remains fraught. We argue that dominant typological and structural approaches miscast IDR and underplay the practical work through which it unfolds.

Dive surveys and eDNA detect contrasting macroalgal community composition in Nova Scotia, Canada

open access: yesJournal of Phycology, EarlyView.
Abstract Morphological identification of macroalgae can be time‐consuming and species may be difficult to observe, collect, or identify, preventing detailed study on the distribution and ecology of many species. The use of eDNA in species surveillance and biodiversity assessments has gained considerable traction in studying macroalgae, as it provides ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Breaking tidal bore: comparison between field data and laboratory experiments [PDF]

open access: yes, 2013
A tidal bore is a surge of waters propagating upstream as the tidal flow turns to rising and the flood tide rushes into a funnel shaped river mouth with shallow waters. The present study focused on the unsteady turbulence induced by a breaking tidal bore
