Care Behavior

The courtship, spawning, and paternal care behavior of lumpfish, Cyclopterus lumpus, in Broad Cove, Newfoundland, are described. Breeding lumpfish are sexually dimorphic and exhibit a distinct sexual dichromatism during reproduction. Spawning females are larger than males and pale blueish green in color. Male lumpfish nuptial coloration consists of a greyish black body and an orange–red ventral surface and fins. Spawning follows an extended courtship involving nest cleaning, fin brushing, and quivering. Females extrude pink eggs onto the surface of the nest which the male fertilizes. After fertilization, males mold the eggs into the nest, producing funnel-like depressions in the egg mass. Males remain with the eggs throughout the incubation period providing parental care. Pectoral fanning and puffing, the expelling of water from the mouth towards the surface of the egg mass, are the predominant parental care behaviors exhibited throughout the incubation period. Quantitative variation between males in the amount of time spent in parental care was independent of male size. Egg masses are maintained free of invertebrate predators by the male, but males are unable to defend eggs against predation by large groups of cunners, Tautogolabrus adspersus. Puffing behavior was more frequent towards the end of the incubation period than at the beginning. During hatching emergent larvae are swept from the nest site by male fanning and puffing behaviors.

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.

Nutritional Status Of Children

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.
