The Rosette Complex in the constellation of Monoceros is a magnificent laboratory for the study of star formation. The region presents an interesting scenario, in which an expanding HII region generated by the large OB association NGC 2244 is interacting with a giant molecular cloud. Inside the cloud a number of stellar clusters have formed recently. In this chapter we present a review of past ...

We report ROSAT observations of two molecular clouds previously unstudied in the X-ray band, examining the possibility that X-rays can serve as tracers of star formation at distances >∼ 1 kpc. The targets are the molecular clouds associated with the Monoceros R2 reflection nebula (d = 0.8 kpc) and with the Rosette giant HII region (d = 1.5 kpc). In both cases, the PSPC images show point sources...

The Monoceros R2 region was first recognized as a chain of reflection nebulae illuminated by Aand B-type stars. These nebulae are associated with a giant molecular cloud that is one of the closest massive star forming regions to the Sun. This chapter reviews the properties of the Mon R2 region, including the namesake reflection nebulae, the large scale molecular cloud, global star formation act...

The osmoregulatory ability and salinity tolerance of four species of decapod crustaceans (Decapoda: Natantia) were evaluated to test the degree of physiological adaptation to variations in salinity (2 d exposure to 10, 20, 25 and 32. The ecophysiological salinity tolerance of two penaeids (Metapenaeus joyneri and Penaeus semisulcatus) and two palaemonid species (Palaemon pacificus and Exopalaem...

Based on 203 specimens belonging to the Rhinolophus "pusillus group" (Mammalia: Chiroptera: Rhinolophidae), univariate and multivariate morphometric analyses using 19 characters were performed to assess the confused species taxonomy. The results indicated that R. pusillus (including calidus, parcus, and szechuanus) in the continental region and Hainan Island of China and "R. cornutus" in Japan ...
