Journal article (peer-reviewed)abstract
- Ongoing Arctic greening can increase productivity and reindeer pasture quality in the tundra. However, greening may also entail proliferation of unpalatable species, with consequences for pastoral social-ecological systems. Here we show extensive greening across 20 reindeer districts in Norway between 2003 and 2020, which has reduced pasture diversity. The allelopathic, evergreen dwarf-shrub crowberry increased its biomass by 60%, with smaller increases of deciduous shrubs and no increase in forbs and graminoids, the most species rich growth forms. There was no evidence for higher reindeer densities promoting crowberry. The current management decision-making process aims at sustainable pasture management but does not explicitly account for pasture changes and reduced diversity. Large-scale shifts towards evergreening and increased allelopathy may thus undermine the resource base for this key Arctic herbivore and the pastoral social-ecological system. Management that is sensitive to changes in pasture diversity could avoid mismanagement of a social-ecological system in transition.

Research review (peer-reviewed)abstract
- Background: Medicinal plants are still widely used in rural areas of the Philippines. Among the conditions treated with medicinal plants are those related to pregnancy, childbirth, and postpartum care. This systematic review identified the medicinal plants used for obstetric care in the country. Methods: The study was conducted based on the PRISMA flow diagram, starting with a data search using three databases. The necessary information was extracted from the eligible research papers, and the studies' quality was assessed through a developed quality assessment tool. Results: This study included 38 ethnobotanical studies with 153 plant species used for pregnancy and postpartum care. Most of the studies were conducted in Northern Mindanao, in the Philippines. The most common pregnancy-related indications for the medicinal plants were postpartum care, and postpartum bleeding topped the list. The most common plant family, genus, and species were Fabaceae, Ficus, and Moringa oleifera Lam, respectively. The leaf was the most common single plant part used for pregnancy and postpartum care. Only 80 medicinal plants had toxicologic and teratogenic data. Conclusion: Women from different ethnic groups widely utilized medicinal plants to treat pregnancy-related conditions. Further research on toxicology and teratogenicity is necessary to ensure the safety of their users.
