Population divergence in nutrient-temperature interactions in Pieris rapae

Abstract Tesim:
The interaction between larval host plant quality and temperature can influence the short-term physiological rates and life-history traits of insect herbivores. These factors can vary locally, resulting in local adaptation in responses to diet and temperature, but the comparison of these interactions between populations is infrequently carried out. In this study, we examine how the macronutrient ratio of an artificial diet determines the larval growth, development, and survival of larval Pieris rapae (Lepidoptera: Pieridae) at different temperatures between two invasive North American populations from different climatic regions. We conducted a fully factorial experiment with three temperature treatments (18°C, 25°C, and 32°C) and three artificial diet treatments varying in terms of the ratio of protein to carbohydrate (low protein, balanced, and high protein). The effects of diet on life-history traits were greater at lower temperatures, but these differed between populations. Larvae from the subtropical population had reduced survival to pupation on the low-protein diet in the cold temperature treatment, whereas larval survival for the temperate population was equally high for all temperature and diet treatments. Overall, both populations performed more poorly (i.e., they showed slower rates of consumption, growth, and development, and had a smaller pupal mass) in the diet with the low protein ratio, but larvae from the temperate population were less sensitive to diet ratio changes at all temperatures. Our results confirm that the physiological and life-history consequences of imbalanced nutrition for insect herbivores may depend on developmental temperatures, and that different geographic populations of P. rapae within North America vary in their sensitivity to nutritional balance and temperature.

Abstract Tesim:
Current approaches to flood management are increasingly insufficient to deal with intensifying flood trends. In this paper, we define and map out the responsibilities and relationships of local, state, and federal governing entities at various levels. We use these relationships to identify gaps in governance needed to address the high financial, human, and infrastructure costs of flooding. This paper offers a description of current flood policies and provides recommendations for innovations in policy solutions to improve governance gaps. We identify three themes from the literature on intergovernmental relations and flood governance: (1) intergovernmental relations (interlinkages and gaps) for flood governance; (2) risks inherent to flood governance (financial, physical, social and individual, and perception of risk); (3) data adequacy and interoperability.

Editorial: Curbing global warming with multi-scale and multi-sectoral Water-Energy-Food nexus

Date of publication:

Abstract Tesim:
Food, energy, and water play fundamental roles in human life and development. The rapid growth of global population requires increasing demand for agriculture product, renewable energy, and water resource supplies. Such demands echo with the United Nation’s Sustainable Development Goals (SDGs), especially zero hunger (Goal 2), clean water and sanitation (Goal 6), and affordable and clean energy (Goal 7) in the shared blueprint for people and planet’s future.

The Air Pollution Human Health Burden in Different Future Scenarios That Involve the Mitigation of Near-Term Climate Forcers, Climate and Land-Use

Abstract Tesim:
Elevated surface concentrations of ozone and fine particulate matter (PM2.5) can lead to poor air quality and detrimental impacts on human health. These pollutants are also termed Near-Term Climate Forcers (NTCFs) as they can also influence the Earth's radiative balance on timescales shorter than long-lived greenhouse gases. Here we use the Earth system model, UKESM1, to simulate the change in surface ozone and PM2.5 concentrations from different NTCF mitigation scenarios, conducted as part of the Aerosol and Chemistry Model Intercomparison Project (AerChemMIP). These are then combined with relative risk estimates and projected changes in population demographics, to estimate the mortality burden attributable to long-term exposure to ambient air pollution. Scenarios that involve the strong mitigation of air pollutant emissions yield large f
