The structure and development of the brain are extremely difficult to study in free-ranging marine mammals. Here, we report measurements of total white matter (WM), total gray matter (GM), cerebellum (WM and GM), hippocampus, and corpus callosum made from magnetic resonance (MR) images of fresh, postmortem brains of the Atlantic white-sided dolphin (Lagenorhynchus acutus) imaged in situ (i.e., ...

Marine biology is a hybrid subject that combines aspects of organismal function, ecological interaction and the study of marine biodiversity.[1] The earliest studies of marine biology can be traced back to the Phoenicians and the Greeks who are known as the initial explorers of the oceans and their composition.[2] However, it was Aristotle (384-322 BC) who was the first to record any observatio...

Environmental Decision Support Systems (EDSS) constitute an important emerging technology for the management of marine environments and resources world-wide. A requirement for such systems is the provision of accurate and comprehensive data on marine animal populations and habitats. Underwater video is increasing in importance as a technology for collecting this data, but manual analysis of the...

Marine monitoring systems have the requirements of a large field of view, low power consumption, real-time viewing, and economical and automatic functionality. This paper establishes an omnidirectional vision system used in marine buoys that meets these requirements. We present a framework for image stabilization, which is achieved by omnidirectional sea-skyline detection in a marine environmen...

several species of magnetotactic bacteria have been discovered recently. these bacteria synthesize intracellular magnetic nanoparticles in specific sizes and shapes and arrange them in chains. these particles called magnetosomes and can be used for drug-delivery, cell-targeting and hyperthermia. magnetotactic bacteria navigate along the magnetic field; this process is known as ‘magnetotaxis’ wh...

A new method of three-dimensional (3-D) analysis of sclerotised structures of monogenoids was performed by processing z-series images using 3D-Doctor. Z-series were obtained from Gomori's trichrome-stained specimens of marine and freshwater monogenoids under laser scanning confocal fluorescence microscopy. Measurements obtained from 3-D images were then compared with those from 2-D images taken...

Human activities in the sea, such as intensive fishing and exploitation of offshore wind farms, may impact negatively on marine mega fauna. As an attempt to control impacts, surveying, tracking animals are often performed sites where those take place. Nowadays, thank high resolution cameras development machine learning techniques, wild can be remotely analysis acquired images automatized using ...
