Crocodilians are apex amphibious predators that occupy a range of tropical habitats. In this study, we examined whether their semi-aquatic lifestyle and ambush hunting mode are reflected in specific adaptations in the peripheral visual system. Design-based stereology and microspectrophotometry were used to assess spatial resolving power and spectral sensitivity of saltwater (Crocodylus porosus)...

As part of a large hydroelectric project in northern Québec (Canada), a portion of the flow of the Rupert River was diverted toward the existing La Grande hydroelectric complex. As a result of the partial diversion, the discharge of the Rupert River at its mouth is reduced by an average of 50% annually. This corresponds to an 18% decrease in the total freshwater inflow into the bay and, thus, t...

Saltwater intrusion occurs in coastal areas worldwide and a theoretical investigation of its sources is crucial because dissolved salts are probably the most common contaminants in freshwater. In the case of coastal aquifers, contamination arises from saltwater invasion, caused primarily by human activities due to heavy urbanisation. Hence, there is a need to predict the location and movement o...

We proposed new electrodes that are applicable for electrocardiogram (ECG) monitoring under freshwater- and saltwater-immersion conditions. Our proposed electrodes are made of graphite pencil lead (GPL), a general-purpose writing pencil. We have fabricated two types of electrode: a pencil lead solid type (PLS) electrode and a pencil lead powder type (PLP) electrode. In order to assess the quali...

Ammonia-oxidizing archaea (AOA) outnumber ammonia-oxidizing bacteria (AOB) in many terrestrial and aquatic environments. Although nitrification is the primary function of aquarium biofilters, very few studies have investigated the microorganisms responsible for this process in aquaria. This study used quantitative real-time PCR (qPCR) to quantify the ammonia monooxygenase (amoA) and 16S rRNA ge...

Delineating the actual location and shape of the freshwater-saltwater transition zone is a prerequisite for long-term prediction of groundwater quality in coastal regions. Two sites with saltwater intrusion problems in Mallorca are currently investigated within the framework of the European research project ALIANCE. Whereas the extent of the saltwater intrusion is well known and easy to underst...

This essay examines the recent group exhibition SALTWATER / Interconnectivity co-curated by Katharine Losi Atafu-Mayo and Giles Peterson at Tautai Gallery in Auckland, Aotearoa New Zealand (October 16, 2020 to January 30, 2021), including its public talks, forums, performance activations. The was intended embody Moana worldview explore questions of justice, equity, identity, ecology through new...
