A novel olfactory method for bacterial species identification using an electronic nose device called the MonoNose was developed. Differential speciation of micro-organisms present in primary cultures of clinical samples could be performed by real-time identification of volatile organic compounds (VOCs) produced during microbial replication.

The free-living solitary mushroom coral Heliofungia actiniformis resembles sea anemones by having large, fleshy polyps with long tentacles, which provide shelter to symbiotic organisms. Commensal shrimps are well studied, but little is known about associated fish fauna. Therefore, the associated fauna of 118 coral polyps of H. actiniformis was examined at a(More)
Archaster typicus, a common sea star in Indo-Pacific regions, has been a target for the ornamental trade, even though little is known about its population biology. Spatial and temporal patterns of abundance and size structure of A. typicus were studied in the Davao Gulf, the Philippines (125°42.7 0 E, 7°0.6 0 N), from February 2008 to December 2009.(More)
Although the presence of fish on coral colonies and individual polyps of the Anthozoa is relatively common (e.g., Munday et al. 1997), the only fish known to be associated with Heliofungia actiniformis is the white pipefish Siokunichthys nigrolineatus (see Hoeksema et al. 2011). Other fishes may hover over individuals of this large solitary coral polyp, but(More)
The Egyptian weasel (Mustela subpalmata) is a small mustelid with a distribution restricted to the lower Nile Valley and the Nile Delta. Traditionally considered a subspecies of the least weasel (M. nivalis), it is currently recognized as a separate species based on morphology. Here we present the first genetic assessment of the taxonomic status of the(More)
Paracorynactis hoplites (Haddon and Shackleton 1893) (Anthozoa: Corallimorphidae) was recently assigned to the new monotypic genus Paracorynactis based on specimens from Indonesia and observations in the Philippines (Ocaña et al. 2010). Shortly after, this species was reported from the western Indian Ocean without locality data (Den Hartog and Ocaña 2011),(More)
The population ecology of the sand dollar Sculpsitechinus auritus was studied in shallow coastal habitats of the Gulf of Suez, Egypt, from January 2013 to October 2014. Bimonthly sampling revealed that 95 % of the individuals had a width of 100–145 mm and that juveniles were absent throughout the sampling period. The mean gonadosomatic index (GSI) reached(More)
Introduced mammalian predators have negatively affected native biota and ecological processes in ecosystems across the globe. The least weasel (Mustela nivalis) is a Holarctic mustelid carnivore that has been considered one of the world’s worst invasive alien species. It has been introduced to several islands in the Mediterranean Sea and Atlantic Ocean, and(More)
Individuals of the rabbitfish Siganus rivulatus (Siganidae) and surgeonfish Zebrasoma desjardinii (Acanthuridae) were observed feeding on ctenophores and scyphozoans in the northern Red Sea during late spring and early summer seasons between 2010 and 2015. Siganus rivulatus and Z. desjardinii, considered nominally herbivorous, preyed on relatively large(More)
