Current mitigation strategies against invasive tunicates on mussel aquaculture gear in Prince Edward Island concentrate on labour-intensive and costly fouling removal. Instead of removal, this study focused on preventing the settlement of the vase tunicate Ciona intestinalis and other fouling organisms by applying a layer of food grade oil to gear prior to recruitment. Laboratory tests established the adherence and persistence of shortening, a food grade oil with a melting point exceeding ambien...

An analysis of energy input-output in boro rice cultivation was undertaken for well recognized salinity classes (S1 -S5 ) and farm categories (landless, marginal, small, medium, and large) in south-west coastal Bangladesh. A total of 125 target farmers were surveyed by using structured questionnaire during the boro season (January-May 2011). Survey data were converted into energy by using the respective energy co-efficient equivalents. The results revealed that the sequences of total energ...

Abstract The South African coastline can be divided into at least four temperature-defined marine bioregions, including the tropical north-east coast, the subtropical east coast, the warm-temperate south coast, and the cool-temperate west coast. There are also two biogeographical transition zones, the south-west coast and the south-east coast (or Wild Coast). The former is sometimes considered a distinct marine bioregion, but no such status has yet been suggested for the Wild Coast. Previous dat...

Abstract Background Poor glycemic control in Type 1 Diabetes (T1D) patients is strongly associated with an increased risk of diabetes-related microvascular complications later in life, but it is unclear whether short period of poor glycemic control in children with T1D can cause evident microvascular morphological changes long before any pathological manifestation. Our study aimed to investigate the longitudinal association between poor glycemic control and subsequent changes in retinal microvas...

Abstract Coal is primarily beneficiated by wet gravity methods. The wet processing of coal is an efficient practice. However, it introduces the moisture in the range of 6%–15%, depending upon the size of coal which is as detrimental as ash content to the heating value of coal. Dry beneficiation of coal fines was carried out using an air fluidized vibrating table in which the coal particles get separated from the heavier mineral particles as a result of horizontal and vertical stratification. Two...

A key challenge in small-scale fisheries that use moored fish aggregating devices (mFADs) is the ability to accurately quantify multi-sector fishing activity through fishery-independent methods. Here, we present a novel fishery-independent assessment of multi-sector fishing activity associated with a newly developed open access mFAD programme off San Juan, Puerto Rico. We identified three fishing sectors (recreational, charter and commercial) and 158 individual fishing vessels that routinely ope...

Purpose: The appropriate management of infected obstructing ureteral calculi is prompt genitourinary decompression. Urine cultures are the gold standard for confirming infection but often take 24–48 h to result. Although white blood cell (WBC) count is an important diagnostic laboratory test, it is a nonspecific inflammatory marker. Similarly, urinalysis (UA) can be misleading in the setting of a contaminated sample, bladder colonization, or in cases of a completely obstructed the upper urinary ...

The retina of Metynnis roosevelti Eigenmann, 1915, a very active freshwater fish, was investigated by light and electron microscopy and was found to have a complex neuronal structure that allows rapid responses of visual stimuli. Retina photoreceptors are double cones, single long cones, single short cones and rods. Cone inner segments are arranged as mosaics. The outer nuclear layer contains small nuclei of twin cones, long and wide nuclei of long single cones, spherical large nuclei of short c...

The absorption of anthropogenic atmospheric carbon dioxide (CO<sub>2</sub>) by the ocean provokes its acidification. This acidification may alter several oceanic processes, including the export of biogenic carbon from the upper layer of the ocean, hence providing a feedback on rising atmospheric carbon concentrations. The effect of seawater acidification on transparent exopolymeric particles (TEP) driven aggregation and sedimentation processes were investigated by studying the interactions betwe...

Aim: The Nile tilapia - Oreochromis niloticus(Linnaeus 1758) - is an exotic omnivorous filter-feeding fish that has been stocked for three decades in man-made lakes of Northeastern Brazil. Most experiments manipulating omnivorous filter-feeding fish in eutrophic lakes and reservoirs shows that their presence tends to increase phytoplankton biomass and primary production. In this study, we tested the hypothesis that tilapia interact synergistically with nutrient enrichment so that the effects of ...

Over the recent years, the use of containers in the transport system has dramatically increased. The rise of world containerisation is the result of the interplay of macroeconomic, microeconomic and policy-oriented factors. World trade is facilitated through the elimination of trade barriers and the liberalisation and deregulation of markets. Market liberalisation revealed a demand for enhancing the development of logistics services throughout the world. In the conceptual metamorphosis of the tr...

Large-scale anthropic intervention in the coastal zone started mainly in the 19th century due to the need to accommodate increasingly larger ships in the port areas, and to the diffusion of the value of beaches as places for sea-bathing. Throughout the 20th century, urban growth of coastal areas increased, and it is where, nowadays, some of the largest cities in the world are established. Also, several popular tourist destinations are found in the coastal areas, creating a huge flux of people. I...

The composition of marine macroinvertebrates in two localities (Isla Palma and Los Negritos) of Malaga Bay was studied. This bay is located in the Pacific coast of Colombia and was recently declared National Natural Park. The rapid ecological assessment revealed a total of 128 species belonging to 64 families and 11 classes (including threatened species). The most common groups were: Gastropoda (27%), Polychaeta (26%), Malacostraca (16%) and Pelecypoda (13%). Even though the two sites are relati...

Small headwaters streams of the Neotropical region usually have high species richness and diversity. This study aimed to investigate the species composition and abundance of fish fauna in the headwaters streams of the Madeira-Purus interfluvial plain in the Brazilian Amazon. A total of 22 streams of 1st to 3rd order were sampled during two expeditions at two separate locations in April-May and July of 2007. A total of 5508 fishes were captured using hand and small seine nets, belonging to 78 spe...

The main ecosystem in northern Patagonia, Argentina, is the Monte, a semi-desert scrubland home to a high biodiversity. Monte is the most endangered ecosystem of southern South America, with an annual rate of clearance of the native vegetation estimated at 3.7%. Here we report the results of bird surveys carried out in the province of Río Negro, northern Patagonia. We surveyed four localities mostly dominated by the Monte ecosystem, between 1986 and 2010. Three localities are Important Bird Area...

Bromeliaceae is one of the most representative plant families in restinga habitats. We analyzed the species richness and composition of Bromeliaceae in 13 restinga habitats along the Brazilian coast. We found a total of 41 species distributed along the restinga habitats studied. The restinga of Praia do Sul, in the state of Rio de Janeiro, had the highest number of species (15), whereas the restinga of Abaeté, in the state of Bahia, had the lowest (4). Our data are suggestive that the Doce River...

Abstract Background Local adaptation of marine and diadromous species is thought to be a product of larval dispersal, settlement mortality, and differential reproductive success, particularly in heterogeneous post-settlement habitats. We evaluated this premise with an oceanographic passive larval dispersal model coupled with individual-based models of post-settlement selection and reproduction to infer conditions that underlie local adaptation in Sicyopterus stimpsoni, an amphidromous Hawaiian g...

In the last two decades, genetic and genomic studies have revealed the astonishing diversity and ubiquity of microorganisms. Emergence and expansion of the human microbiome project has reshaped our thinking about how microbes control host health – not only as pathogens, but also as symbionts. In coral reef environments, scientists have begun to examine the role that microorganisms play in coral life history. Herein we review the current literature on coral-microbe interactions within the contex...
