Humans rely on one another to address life’s challenges; research has confirmed that these collections of relationships, or social networks, are also associated with important health outcomes. However, there has been little in-depth research on how the characteristics of people in networks, like age or income, and the types of support they provide, might be associated with health. Leah Isquith-Dicker joins us to share research on the social networks of women in informal settlements on the outskirts of Lima, Peru, who are raising their children far from their natal families. She shares findings on the additional challenges these women face related to poverty and the fight for basic services, and the impact of their social networks on their health.
Coastal upwelling is a wind-driven process that occurs during the summer when wind blows southward along the coast, pushing water offshore, and causing deep, nutrient-rich water to fill the void left behind. Phytoplankton (and other primary producers) use these nutrients to grow, providing food for larger animals and in turn feeding commercial fisheries in our region. Hally Stone sheds light on the coastal upwelling cycle, and reveals how variability in wind patterns can affect the productivity of fisheries through its influence on the nutrient supply.
Why and how do numerous tree frog species live where they do? Itzue Caviedes Solis joins us to discuss the variation in swimming speed and behavior in Mexican tree frogs—how the lengths of their limbs and their different habitats influence the patterns of their swimming. She outlines how these characteristics evolved in closely-related species, and how these variations influence the different species of Mexican tree frogs and the locations they call home.
