Human bartonellosis is found predominantly in Perú2, 6, 8, 12, 15, as well as in Ecuador3, 7, 10 and Colombia13, 15. In Peru, the disease is restricted to the valleys of the western-side and a few inter-andean and eastern-slopes of the andean valleys6, 15, 18 at altitudes between 1000 and 3200 masl. Most human cases are reported from the regions of Chavin, Nor Oriental del Marañon and Lima16. Lutzomyia verrucarum is presumed to be the only vector of human bartonellosis in the valleys of Peru1, 2, 8, 11, 17, 19/ Our research objetive was to detect the presence of Lu. verrucarum in various localities known to be endemic for human bartonellosis in three provinces of Region Nor Oriental del Marañon. Sandfly collections were made between 1987 and 1992 during four visits to bartonellosis-endemic provinces: San Ignacio (districts of San José de Lourdes: 1020-1260 m and La Coipa: 1200-1560 m), Jaén (districts of Santa Rosa: 1300-1680 m and Jaén: 1220-1680 m) and Utcubamba (districts of Lonya Grande: 1200 m and El Milagro: 1200-1540 m
Resumen. Se describen e ilustran dos especies colombianas de Magnolia, nuevas para la ciencia, provenientes del departamento de Antioquia. Magnolia coronata se distingue por un anillo de indumento lanoso dorado presente en el entrenudo más joven de las ramillas. Magnolia jardinensis se caracteriza por las numerosas puntuaciones presentes en los pétalos más externos y por la pubescencia lanosa y amarillenta. Se presentan los primeros registros para Colombia, en el departamento de Santander, de la especie Magnolia chimantensis, conocida hasta ahora solamente por la colección del tipo proveniente de Chimantá, en Venezuela.Palabras clave: Antioquia, Colombia, Magnolia, Magnoliaceae, Santander.Abstract. Two new Colombian species of Magnolia from Antioquia are described and illustrated. Magnolia coronata can be distinguished by a ring of woolly, golden pubescence present in the youngest internodes of the branches. Magnolia jardinensis has numerous punctations on the outermost petals and a woolly, yellowish pubescence. Magnolia chimantensis, a species previously known only from the type locality in Chimantá, Venezuela, is reported for the first time from Santander, Colombia.
The objective of this study was to evaluate the yield, nutritional composition, and digestibility of conventional (CON) and brown midrib (BMR) pearl millet (PM) with different establishment dates, maturity at harvest and when mixed with cowpea (CWP). In trial 1, CON and BMR were planted on two different dates. In trial 2, CON and BMR, mixed or not with CWP, were harvested when PM was at the boot or heading stages. In trial 1, dry matter (DM) yield was similar between both PM genotypes but delaying establishment reduced DM yield by 30%. Additionally, BMR had a lower concentration of acid detergent lignin (ADL) and a higher in vitro neutral detergent fiber digestibility (IVNDFD) compared to CON. In Trial 2, the DM yield was 7.3% higher for CON compared to BMR, and PM with the BMR trait had a lower level of ADL and higher IVNDFD compared to CON. Mixing PM with CWP had negligible effects on nutritional composition but reduced DM yield by 8.3%. Results of these studies indicated that fiber from BMR PM is more digestible than CON but, in one of the trials, this occurred at the expense of lower DM yield. Mixing CWP with PM negatively impacted DM yield.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
