The geology of the Darien province of eastern Panama is presented through a new geologic map and detailed biostratigraphic and paleobathymetric analysis of its Upper Cretaceous to upper Miocene sediments. The sequence of events inferred from the stratigraphie record includes the collision of the Panama arc (the southwestern margin of the Caribbean plate) and South American continent. Three tect...

OBJECTIVE To estimate mortality from diabetes mellitus (DM) for the period 2001-2011 in the Republic of Panama, by province/indigenous territory, and determine its relationship with biological and socioeconomic risk factors. METHODS Cases for the years 2001-2011 with DM listed as the principal cause of death were selected from Panama's National Mortality Registry. Crude and adjusted mortality...

Quillaia extracts (synonyms: quillaja extracts, bois de Panama, Panama bark extracts, quillai extracts, Quillay bark extracts, soapbark extracts; C.A.S. no. 68990-67-0, INS no. 999) are obtained by aqueous extraction of the milled inner bark or whole wood of Quillaja saponaria Molina (family Rosaceae), which is a large evergreen with shiny, leathery leaves and a thick bark, native to China and ...

The new genus Ampliphax, assigned to the Delphacini, is described and illustrated with a single new species A. grandis from Costa Rica and Panama. Ampliphax grandis is a large species with a projected head. DNA barcode data suggest, among currently barcoded taxa, an affinity to the genus Bostaera. A checklist of the delphacid species from Costa Rica, Panama, and Nicaragua based on literature an...

Anopheles malefactor Dyar and Knab is elevated from synonymy with An. punctimacula Dyar and Knab, and both species are described and illustrated. Primary morphological differences in the adult, pupal, and larval stages are provided for the separation and recognition of these species. An. punctimacula occurs from Mexico to northern Colombia and Venezuela, whereas An. malefactor is restricted to ...

The need for efficient buildings to contribute sustainable development has led the proposal of goals and regulations in different countries linked net zero energy objectives, following approaches specific their regions. Such are not yet developed a developing country such as Panama. Thus, this study develops first framework Zero Energy Districts (ZED) Panama based on passive active solutions th...

Barucynips panamensis Medianero & Nieves-Aldrey, a new genus and species of oak gallwasps (Hymenoptera: Cynipidae: Cynipini), is described from adults reared from galls on Quercus bumelioides in Panama. The new genus is taxonomically close to the recently described Coffeikokkos from Costa Rica, but differs from it and all of the described genera of Cynipini, by the shape and setation of the pro...
