The isolated Isla del Coco experiences periodic, extreme disturbances which devastate coral reefs surrounding the island. Scleractinian corals build the physical structure of the reef therefore ecosystem recovery relies on coral species recovery. Coral recruits can be of sexual or asexual origin, and the relative success of the two recruit types influences the speed and spread of recovery processes. Here we focus on the massive coral, Porites lobata, because it is the main reef-builder around Is...

In this paper, a simplified analytical method used to predict the residual ultimate strength of a ship hull after a shoal grounding accident is proposed. Shoal grounding accidents always lead to severe denting, though not tearing, of the ship bottom structure, which may threaten the global hull girder resistance and result in even worse consequences, such as hull collapse. Here, the degree of damage of the bottom structure is predicted by a series of analytical methods based on the plastic-elast...

<p>Fish farmer cannot reduce feed price, however they can reduce feed cost for fish producing. Feed cost is highly determined by feeding rate (FR); whether in maximum FR or restricted FR, and dissolved oxygen level in water. The present paper reviews a detail explanation concerning both factors on feed efficiency. Amongst other water quality parameters, oxygen is the most important factor and therefore must be closely monitored. Moreover, dissolved oxygen cannot be detected only by visual observ...

In oligotrophic ocean waters where bacteria are often subjected to chronic nutrient limitation, community transcriptome sequencing has pointed to the presence of highly abundant small RNAs (sRNAs). The role of sRNAs in regulating response to nutrient stress was investigated in a model heterotrophic marine bacterium Ruegeria pomeroyi grown in continuous culture under carbon (C) and nitrogen (N) limitation. RNAseq analysis identified 99 putative sRNAs. Sixty-nine were cis-encoded and located antis...

While there is considerable interest in, and good evidence for, the role that parasites play in biological invasions, the potential parallel effects of species introduction on parasite dynamics have clearly received less attention. Indeed, much effort has been focused on how parasites can facilitate or limit invasions, and positively or negatively impact native host species and recipient communities. Contrastingly, the potential consequences of biological invasions for the diversity and dynamics...

Spawning frequency and batch fecundity were estimated for Brazilian flathead, Percophis brasiliensis, in Argentine coastal waters. Samples of this species were collected during the spawning period in November 1998 and 1999. Spawning frequency, determined using the percentage of females with postovulatory follicles, was about 17% during November 1998. This percentage indicates that P. brasiliensis spawned, on average, once every 6 days during this month. Batch fecundity, estimated from counts of ...

Tilapia (Oreochromis sp.) is the most important and abundant fish species in Brazil due to its adaptability to different environments. The development of tilapia-based products could be an alternative in order to aggregate value and increase fish meat consumption. However, there is little information available on fishburger freezing and cooking in the literature. In this work, the mathematical modeling of the fish burger baking was studied. Previously to the baking process, the...

The Arctic sea ice cover has changed drastically over the last decades. Associated with these changes is a shift in dynamical regime seen by an increase of extreme fracturing events and an acceleration of sea ice drift. The highly non-linear dynamical response of sea ice to external forcing makes modelling these changes and the future evolution of Arctic sea ice a challenge for current models. It is, however, increasingly important that this challenge be better met, both because of the important...

Background The research on values constitutes an essential part of social research. These studies usually use an approach associated with the lists of values and their evaluations on scales, ranging or comparative. This approach is problematic, particularly in the situation of youth who are often characterized by low reflectiveness. One of the ways to achieve the value is to conduct research on practical plans. Participants and procedure The study involved 218 pupils from three lower sec...

Introduction: After cellulose, Chitin is the most abundant biopolymer in nature. The most important derivative of chitin is chitosan, obtained by deacetylation of chitin. Major sources of chitin are the exoskeleton of marine crustaceans such as crab, shrimp, and krill. Chitin extraction from shrimp shells can be carried out chemically or using biological methods. Microbial fermentation as an eco-friendly procedure is a suitable alternative for the chemical and enzymatic processes. In this study,...

In high-nutrient–low-chlorophyll regions, phytoplankton growth is limited by the availability of water-soluble iron. The eruption of Kasatochi volcano in August 2008 led to ash deposition into the iron-limited NE Pacific Ocean. Volcanic ash released iron upon contact with seawater and generated a massive phytoplankton bloom. Here we investigate this event with a one-dimensional ocean biogeochemical column model to illuminate the ocean response to iron fertilisation by volcanic ash. The results i...

Mediterranean temporary wetlands have considerably declined in recent decades. Today, opportunities arise for the restoration of these wetlands due to land-use changes, such as the abandonment of cultivation. One critical question is whether communities, such as those observed in natural temporary wetlands, can develop alone or if active restoration should be implemented. In a series of experimental mesocosms, we transferred soil from several temporary wetlands chosen as a set of refere...
