Abstract:

Background Youth population (10-24 years of age) comprises more than 30% of the total population in Nepal. This is the age when values are formed, many become sexually active and begin to develop a pattern of risky sexual behaviour. This makes youth more vulnerable to contacting sexually transmitted diseases including HIV/AIDS. The main objective of this study was to assess the sexual behavior among school youths of a rural far-western district, Achham, Nepal.Methods A cross sectional study was conducted among school youths aged 15 to 24 years studying at grade 11 and 12 in Achham district.

They are: L. australiae Herrich-Schaeffer from the south-western coastal area of Western Australia, L. cervantes, sp. nov., from southern Western Australia, and L. luteomaculatus, sp. nov., from western Victoria and adjacent South Australia.

The absence of marine records for M. dalli below latitude 31�S., together with data on gonadal stages and spermatophore deposition on females of this species in the Swan estuary, provide very strong indications that the western school prawn typically breeds in estuarine environments in south-western Australia. The 0 + recruits, which first appeared in samples in February, remained in the estuary during the following months and by November had reached a size suitable for exploitation. At this time they were approaching sexual maturity and were starting to move from the shallows to the deeper wa

Inflorescences and flowers on male and female trees are similar in overall appearance, except that the flower parts on males are larger and flowers open more widely. Even the gynoecia on male plants are larger in most respects. We also report that although trees retain their gender, th

Abstract:

Sexual segregation is best known in sexually dimorphic ungulates. Many hypotheses have been proposed to explain the evolution of sexual segregation in ungulates, but all are reducible to the influence of two factors: body size and sex-specific reproductive strategy. Definitive tests of these hypotheses are lacking in ungulates because these factors are confounded, all males being somewhat larger than females. Kangaroos represent a parallel radiation of terrestrial herbivores, but their populations are composed of a spectrum of adult body sizes, ranging from small males the same size as females

Sexual dimorphism is demonstrated in pink snapper, Pagrus auratus (Sparidae), from the Shark Bay region of Western Australia, by canonical variate analysis of 13 morphometric measurements of the head. Snapper of both sexes develop a prominent hump on the forehead as they grow to large size, but the males do so to a greater extent than the females. Males also develop a bulge on the snout which was not found in females. Snapper with humps are less well accepted in an export market and this may result in high-grading problems in the quota-managed commercial fishery. Morphometric differences betwe

Proportional allocations of current total dry matter (DM), N and P to early season asexual gemma production and late-season flowering and seed production were compared for eight pygmy rosette form and three micro stilt-form perennial pygmy sundews (Drosera spp.) in native habitat in south-western Australia. Mean allocations to gemmae for the smaller rosette species were 22% for DM, 60% for N and 38% for P versus 8, 20 and 23% (DM, N, P) respectively for the micro stilt forms. Allocations to mature fully formed seeds were extremely low, 1-8, 4.0 and 5.4% (DM, N, P) for the rosette forms, 0.7, 3

Abstract:

The biology of the nightfish, Bostockia porosa, is described on the basis of data obtained from monthly samples collected from the southern branch of the Collie River in south-western Australia during 1984, 1985 and 1988. It is estimated that most of the 2463 fish caught during those years belonged to either the 0+ (81.8%) or 1 + (12.5%) age classes. Representatives of the 2+ and 3+ age classes contributed 4.2 and 1.0% respectively, and one fish as old as 6+ was found. The parameters of the von Bertalanffy growth curves (La∞ K and to) were, respectively, 92, 0.818 and -0.151 for males and 104,

Climate change, associated with increased aridity, and high grazing pressure by livestock results in the scarcity and loss of perennial Poaceae in arid ecosystems. The species threatened by this include Cenchrus ciliaris L., a native perennial grass of the tropical and sub-tropical arid rangelands of Africa and Western Asia and now introduced in Central and South America, and Australia. This species reproduces predominantly through aposporous apomixis although sexual individuals have been occasionally identified. Cenchrus ciliaris is characterised by a significant, heritable, phenotypic polymo

Abstract Understanding individual interactions within a community or population provides valuable insight into its social system, ecology, and, ultimately, resilience against external stimuli. Here, we used photo-identification data, generalized affiliation indices, and social network analyses to investigate dyadic relationships, assortative interactions, and social clustering in the Australian humpback dolphin (Sousa sahulensis). Boat-based surveys were conducted between May 2013 and October 2015 around the North West Cape, Western Australia. Our results indicated a fission–fusion society, ch

Abstract:

The reproductive biology of Euastacus bispinosus populations was studied in a river and a creek of the Glenelg River system in south-western Victoria, and a small coastal creek in south-eastern South Australia. Females produced eggs in the first breeding season after maturation of their gonopores. At the Victorian sites, E. bispinosus spawned in early May, carrying eggs for about seven months before hatching and juvenile release in October-December. At least 95% of mature females at each Victorian site carried eggs during the breeding season. Mature females had relatively broader abdomens than

This study examined profiles of self-reported child physical abuse, sexual abuse, emotional abuse, and neglect among incarcerated juveniles in Victoria, Australia, using latent class analysis. We

Vidal and Austen, however, could not serve as emblematic figures for this campaign, and not only because the two men had no interest in marriage.

This way of seeing men and women is more than aesthetic choices but in fact shapes our ideologies of gender. As Berger asserts: “The art of the past no longer exists as it once did… In its place there is a language of images. What matters now is who uses that language for what purpose” (33).What happens when there are no historical images that represent your identity? How do others learn to see you?

Millions of young people his age joined the various ‘movements’ of the day after experiences that changed their lives—mostly music but also drugs or fashion.
