AbstractFrogs of the genus Nyctibatrachus (family Nyctibatrachidae) exhibit a unique reproductive behaviour. They may completely lack or have an abbreviated amplexus, deposit terrestrial eggs and even offer paternal care. We studied the courtship and spawning behaviour of Nyctibatrachus humayuni from Matheran located in the northern region of the Western Ghats of India. The breeding season of N. humayuni coincides with the onset of south-west monsoon. Adult males vocalise from their calling sites on wet rocks/dead logs that often harbour egg clutches and females approach the calling males, resulting in a loose cephalic amplexus that lasts up to 10 minutes. The male dismounts and sits aside; then the female deposits the eggs and moves away from the spawning site or into the water. The mean clutch size and the egg diameter are found to be 30.3 ± 1.89 and 2.44 ± 0.04 mm, respectively. Once the female moves away following spawning, the male slowly moves on to the eggs and fertilises them. The males of N. humayuni appear to be territorial and offer parental care by attending the eggs only during night. Paternal egg attendance most probably reduces the risk of predation by nocturnal predators.

Background Malnutrition is a public health problem in Vietnam. Child health and the status of women have been targets for various health programs in the country. In general, reports in the literature suggest that care is positively correlated with positive nutritional status of children. In the household, the father is considered a resource for care. However, the role of paternal care in health programs has not received the attention it deserves. Objective To identify associations between the involvement of fathers in child care and housework and the nutritional status of children under 3 years of age. Methods This cross-sectional study was based on a random sample of 547 children under 3 years of age from intact families and their biological parents. The main outcome variable was child nutrition. Predictor variables represented two domains of father's involvement. Multivariable general linear modeling and multivariable logistic regression modeling were performed with the use of a combination of stepwise and hierarchical approaches in data analysis. Results The overall prevalence of underweight among children was 19.1%, and the prevalence of stunting was 14.4%. Children whose fathers did not bring them to a medical facility for immunization were about 1.7 times more likely to be underweight and stunted than those whose fathers did bring them for immunization after child's age, household economic status, and mother's education were controlled for. Father's involvement in housework was not found to be related to the prevalence of malnutrition. Conclusions Paternal involvement in child immunization should be encouraged by health-care providers who manage immunization programs.
