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...

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 ...

One hundred specimens of unicorn leatherjacket, Aluterus monoceros purchased from markets of municipalities of Niterói and Rio de Janeiro from May to August 2006. The fishes were measured, necropsied, fileted and analysed their organs. Sixteen fishes were parasitized by nematode Anisakidae: Anisakis spp. and Contracaecum sp. with respectively, 1 and 16% of prevalence, 2 and 3.31 of mean intensi...

The two economically important shrimp species in Bangladesh are the tiger shrimp, Penaeus monodon, and brown Metapenaeus monoceros. However, a continuous decline landing of these from industrial trawling made it critical to assess their stock biomass status explore response present degree removal. Given minimum data requirement robustness, this study employed depletion-based reduction analysis ...

Endosulfan, a broad-spectrum non-systemic organochlorine (OC) pesticide is extensively used to control a wide variety of pests in agriculture, horticulture and public health programmes. Biochemical changes occurring in the metabolically active tissues of gills (GL), hepatopancreas (HP) and muscle (MU) of the penaeid shrimp, Metapenaeus monoceros (Fabricius) on exposure to two sublethal doses (4...
