Journal of Systematics and Evolution, EarlyView.We used a molecular approach to resolve the evolutionary lineages of Neotropical Triplophyllum, uncovering that current species circumscriptions are hindered by high morphological homoplasy in indument characters. Our results support the recognition of three new species and provide a necessary neotypification for T.

Medical and Veterinary Entomology, EarlyView.Larval indices, especially house infestation index (HI) and breteau index (BI), were significantly associated with temperature and precipitation, indicating that warmer and wetter conditions increase Aedes aegypti breeding‐site positivity. Adult indices, trap positivity index (TPI) and adult density index (ADI) showed no significant association with ...

The Effect of Brazil's Family Health Program on Cognitive Skills
Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT This paper examines the effect of Brazil's Family Health Program (Programa Saude da Familia, FHP) on cognitive skills (measured by test scores) of fifth‐grade students. We use biennial data from national exams between 2007 and 2015, and variation in the FHP implementation date across municipalities, birth cohort, and test year to identify the ...
