Respiration and Heart Rate at the Surface between Dives in Northern Elephant Seals [PDF]

open access: yes, 2000
All underwater activities of diving mammals are constrained by the need for surface gas exchange. Our aim was to measure respiratory rate (fb) and heart rate (fh) at the surface between dives in free-ranging northern elephant seals Mirounga ...

Pharmacological Microglial Inhibition Remodels the Scar Microenvironment to Support Reticulospinal Circuit Reconstruction After Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
This study establishes pharmacological microglial inhibition as a therapeutic strategy, demonstrating its capacity to remodel the lesion microenvironment through significant reduction of extracellular matrix deposition. This permissive environmental transformation facilitates robust regeneration of the reticulospinal tract, and reconstructs functional ...

BLENDING RESPIRATORY GAS MIXTURES [PDF]

open access: yesAnnals: Series on engineering sciences (Academy of Romanian Scientists)
The binary or ternary gas mixtures used in diving can be blended either by a successive and controlled injection of the component gases into containers of constant volume, following the pressure in the containers, or by a continuous flow mixing, with ...

Diving in Two Marine Lakes in Croatia [PDF]

open access: yes, 2005
We describe the diving methods used for in-situ observations of the scyphozoan medusa, Aurelia sp., in two marine lakes on the island of Mljet, Croatia. Both lakes have a strong pycnocline at approximately 15 m.

Physiological, morphological, and ecological tradeoffs influence vertical habitat use of deep-diving toothed-whales in the Bahamas

open access: yesPLoS ONE, 2017
Dive capacity among toothed whales (suborder: Odontoceti) has been shown to generally increase with body mass in a relationship closely linked to the allometric scaling of metabolic rates.

Mechanical Cues Regulate Cargo Sorting and Export at the Golgi

open access: yesAdvanced Science, EarlyView.
A pathway is identified linking extracellular matrix stiffness to secretion via Src–FAK–AMPK–GBF1 signaling. Golgi‐localized GBF1 acts as a mechanotransducer whose phosphorylation controls post‐Golgi cargo sorting toward secretion or lysosomal degradation.

THE PROCEDURE BY EVALUATION OF DIVERS FOR THE DEEP DIVING [PDF]

open access: yesAnnals: Series on engineering sciences (Academy of Romanian Scientists), 2014
When a diver is selected to perform a deep diving course, he has to pass a medical test and isn’t affected by the HPNS (High Pressure Nervous Syndrome). When a diver is selected to perform a deep diving course, he has to pass an evaluation stage in order

Wanted Dead or Alive? The Relative Value of Reef Sharks as a Fishery and an Ecotourism Asset in Palau [PDF]

open access: yes, 2011
Over the last 20 years, ecotourism to view and interact with marine megafauna has become increasingly popular (Higham and Lück 2008). Examples of this type of tourism include turtle and whale watching, snorkelling with seals and shark diving (Jacobson ...

Seabird diving behaviour reveals the functional significance of shelf-sea fronts as foraging hotspots

open access: yesRoyal Society Open Science, 2016
Oceanic fronts are key habitats for a diverse range of marine predators, yet how they influence fine-scale foraging behaviour is poorly understood. Here, we investigated the dive behaviour of northern gannets Morus bassanus in relation to shelf-sea ...
