The primary production of fjords across the Arctic and Subarctic is undergoing significant transformations due to the climatically driven retreat of glaciers and ice sheets. However, the implications of these changes for upper trophic levels remain largely unknown. In this study, we employ both bulk and compound-specific stable isotope analyses to investigate how shifts at the base of fjord food webs impact the carbon and energy sources of consumers.

UNICEF Nigeria, Abuja, Nigeria.
Background: Nigerian pregnant and lactating women continue to experience high rates of malnutrition and Nigerian women experience long-term discrimination in the allocation and control of productive resources. Nigeria has policies and a governance architecture in place to advance nutrition, but these commitments lack recognition of how gender equity and nutrition are interwoven.
Objective: To address this gap, this study sought to identify and analyze the influence of gender dynamics and gender norms on nutrition and health-related practices in Nigeria.
