This study was performed to compare the mortality associated with carbapenem-resistant Acinetobacter baumannii (CRAB) and carbapenem-sensitive A. baumannii (CSAB) infections, to identify potential risk factors for CRAB infections, and to investigate the effects of potential risk factors on mortality in CRAB and CSAB patients. This retrospective case-control study was conducted in a universi...

A manned submersible was used in a fjord in southeastern Alaska to study the distributional patterns of the red king crab (Paralithodes camtschaticus) and the Tanner crab (Chionoecetes bairdi) in summer. The cove was divided into three zones: inner, middle, and outer. Six types of habitats, including sand-mud, rock, shell, debris, rock wall, and algae, were identified from video tapes. A relati...

  Baseline ecological studies of Pondicherry mangroves are important for monitoring, management and conservation of mangrove ecosystems. A brachyuran crab faunal assemblage at four stations of Pondicherry mangroves is described and monthly samplings were made during September 2008 – August 2009. Totally 22 species of brachyuran crabs belonging to 12 genera and 5 families were recorded crabs bel...

Models for the diffuse Galactic continuum emission and synchrotron radiation show that it is difficult to reproduce observations of both of these from the same population of cosmic-ray electrons. This indicates that an important contributor to the emission below 10 MeV could be an unresolved point-source population. We suggest that these could be Crab-like sources in the inner Galaxy. Alternati...

Shell selection indices of the dominant hermit crab Clibanarius signatus Heller, 1861, in the Larak Island were studied from September 2011 to June 2012. Among 739 sampled specimens, 41 different gastropod shell types were selected as shelters based on their abundance and local availability. A significant positive correlation (P<0/01) was found between the dimensions of the hermit crab, Cli...

Compared with the elongate bodies of shrimps or lobsters, crabs are characterised by a compact body organisation with a depressed, short carapace and a ventrally folded pleon. The evolutionary transformation from a lobster-like crustacean towards a crab is called ‘carcinization’ and has been interpreted as a dramatic morphological change. Nevertheless, the crab-shape evolved convergently in a n...

Crab waste preserved with .2% NaOCl was mixed with wheat straw, liquid molasses, and water (32:32:16:20, wet basis) and ensiled for a minimum of 8 wk with microbial inoculant. A reduction in pH and water-soluble carbohydrates (WSC) and a higher concentration of lactic acid (4.9%, DM basis) were achieved. The trimethylamine (TMA) concentration in the silage was 11.2 mg N/100 g. In a digestion tr...

reforestation is one of the philippines’ government efforts to restore and rehabilitate degraded mangrove ecosystems. although there is recovery of the ecosystem in terms of vegetation, the recovery of closely-linked faunal species in terms of community structure is still understudied. this research investigates the community structure of mangrove crabs under two different management schemes: p...
