Biodiversity enhances reef fish biomass and resistance to climate change. [PDF]
Proc Natl Acad Sci U S A, 2016 SignificanceMarine fisheries provide a major global source of protein, feeding billions of people, but they face destabilization in many regions from overexploitation and climate change. Using the most comprehensive dataset of fish diversity and abundance, encompassing over 4,500 surveys from nearshore habitats around the world, we show that ...

Fish associated with fish aggregation devices off the Canary Islands (Central-East Atlantic)
Scientia Marina, 1999 Sixteen fish aggregation devices (FADs) were deployed in 50 to 500 m deep of water in the Canary Islands. Species composition and abundance were determined by visual census carried out by divers on 55 occasions from April to October 1995 and from August ...

Global analysis of benthic complexity in shallow coral reefs
Environmental Research Letters, 2023 Three-dimensional shallow benthic complexity (also known as benthic rugosity) reflects the physical conditions of shallow coral reefs environments and can be used to estimate fish biomass and coral cover on reefs.

Analyzing drivers of fish biomass and biodiversity within community fish refuges in Cambodia [PDF]
Ecology and Society, 2019 Freshwater social-ecological systems are shaped by site-specific characteristics, environmental change and annual fluctuations, and the actions of resource users and managers. Our primary aim is to analyze the relative effects of these multifacted forces on fishery productivity and biodiversity using the case of community-managed protected areas within

Advanced Materials Technologies, EarlyView.ABSTRACT Quantifying oral polymorphonuclear neutrophils (oPMNs) is a clinically validated approach for assessing periodontal inflammation. However, current methods, such as manual hemocytometry and flow cytometry, are time‐consuming (>3 h), require invasive sampling, and depend on staining and complex instrumentation, making them unsuitable for point ...

International Aquatic Research, 2017 Microalgae have high nutritional values for aquatic organisms compared to fish meal, because microalgae cells are rich in proteins, lipids, and carbohydrates. However, the high cost for the commercial production of microalgae biomass using fresh water or
