Spatial distribution of the larval indices of Aedes aegypti in Guadalupe, Nuevo León, Mexico, with circular distribution analysis por Mercado Hernández, Roberto, Fernández Salas, Ildefonso, Villarreal Martínez, Homero Fernando

“…Circular distribution was determined by using mean angle (a) and argument (r) from the sum of ranges for each variable. Arguments corresponding to the mean angle of house (260 degrees), recipient (265 degrees), and Breteau (247 degrees) indices were 0.2321, 0.2331, and 0.2225, respectively. …”

Apparent digestibility of dry matter, crude protein, and amino acids of six rendered by-products in juvenile Litopenaeus vannamei por Villarreal Cavazos, David Alonso, Ricque Marie, Denis, Peña Rodríguez, Alberto, Nieto López, Martha Guadalupe, Tapia Salazar, Mireya, Lemme, Andreas, Gamboa Delgado, Julián, Cruz Suárez, Lucía Elizabeth

“…The digestibility of CP in the reference diet (83%) was higher than that observed for all the animal by-product meals except the poultry meals. The ADC of the sum of AA adjusted for nutrient leaching fluctuated from 65% for blood meal to 80% for poultry meals.…”

Pérdidas por intercepción en un bosque de Pinus cooperii C.E. blanco en la región de “El Salto” Durango. por Nava Moreno, Marco Antonio

“…The losses of rain by intercept are measured through different components of precipitation, such as: incident precipitation, net precipitation (direct precipitation plus stemflow) and the storage capacity of the canopy An experiment was developed to measure the hydrological properties of the ecosystem during the period that consisted from 27/02/16 to 04/12/16 obtaining a total of 59 events recording a total sum of 1130.31 mm of incident precipitation, related 80% with 811.3 mm of direct precipitation. …”
