An H-ferritin from the hydrothermal vent shrimp Rimicaris exoculata and its potential role in iron metabolism.

Rimicaris exoculata (Decapoda: Bresiliidae) is one of the dominant species among hydrothermal vent communities along the Mid-Atlantic Ridge. This shrimp can tolerate high concentrations of heavy metals such as iron, but the mechanisms used for detoxification and utilization of excess metals remain largely unknown. Ferritin is a major iron storage protein in most living organisms.

The complete mitogenome of the fairy shrimp Phallocryptus tserensodnomi (Crustacea: Anostraca: Thamnocephalidae).

The sequence of the mitochondrial genome (mitogenome) of the fairy shrimp Phallocryptus tserensodnomi Alonso & Ventura 2013 (Crustacea: Anostraca: Thamnocephalidae) has been determined. It is 16,493 bp with an AT-content of 65.4%, which encodes information of the typical 37 genes as all other metazoan mitogenomes.

[Assessment of ecological environment benefits of reclaimed water reuse in Beijing].

With the rapid development of the social economy and the sustained growth of population, China is facing increasingly serious water problems, and reclaimed water utilization has become an effective measure to solve water shortage problem and to control further deterioration of the ecological environment. Reclaimed water utilization can not only save a lot of fresh water, but also reduce the environmental impact of wastewater discharge, and thus has great ecological environmental benefits, including resource, environmental and human health benefits and so on. This study used the opportunity cost method to construct an evaluation system for ecological environmental benefits of reclaimed water utilization, and Beijing was taken as an example to conduct an estimation of ecological environmental benefits of reclaimed water utilization.

The complete mitogenome of the Atlantic hydrothermal vent shrimp Rimicaris exoculata Williams & Rona 1986 (Crustacea: Decapoda: Alvinocarididae).

In this study we completely determined and analyzed the mitochondrial genome of the Mid-Atlantic Ridge hydrothermal-vent shrimp Rimicaris exoculata (Crustacea: Decapoda: Alvinocarididae). The circular molecule is 15,902 bp in size with an AT content of 65.7%, composed of the same 37 mitochondrial genes as in all other known metazoan mitogenomes.
