Testing 'Proportion of Females Calving' as an indicator for population-level reproductive performance for black rhinoceros (Diceros bicornis).

abstract：:Background. India accounts for 24% to all under-five mortality in the world. Residence in rural area, poverty and low levels of mother's education are known confounders of under-five mortality. Since two-thirds of India's population lives in rural areas, mothers employed in agriculture present a particularly vulnerabl...
