Diversidad de insectos acuáticos y calidad del agua de los ríos David y Mula, provincia de Chiriquí, Panamá.
Se determinó la diversidad, abundancia, distribución, riqueza de insectos acuáticos y la calidad del agua en los ríos David y Mula, en época seca (enero-abril) y lluviosa (julio-octubre) en el año 2010. Los insectos acuáticos se recolectaron dos veces al mes y se utilizaron tres métodos de captura, de acuerdo con el tipo de sustrato. Se identificaron 82 géneros (cuatro sin determinar), agrupados en 43 familias y nueve órdenes de la clase Insecta, con una abundancia total de 14.951 individuos. El río David presentó una diversidad (H’) entre 2,17 y 2,87, y el río Mula entre 2,73 y 2,90. El índice de similitud de Sorensen mostró valores altos de similitud. Según el índice BMWP’/Pan, los ríos David y Mula mostraron aguas de calidad buena o no alteradas de manera sensible a aguas de calidad excelente, excepto en un sitio del río David donde el agua fue de calidad regular, eutrófica y moderadamente contaminada en la época lluviosa. En ambos ríos los datos indican una constancia de los niveles de pH, oxígeno disuelto y conductividad, y además, no presentan cambios significativos notables durante las épocas seca y lluviosa

David Zimmer Christmas letter
This Christmas letter written November 30, 1999, by David Zimmer is titled "Season's Greetings from the last of the Red-Hot-Santas!" It features an illustration of Santa Claus with a guitar, and a summary of Zimmer's year.
David Zimmer (1929-2005) was born in Harrisburg, Ohio. He enlisted in the U.S. Army and served for two years during the Korean War at the Brooke Army Medical Center in San Antonio, where he performed in drag for wounded soldiers. After the war, he returned to Ohio. Zimmer performed as Dolly Divine, a name inspired by the song "Hello Dolly." In 1964, he established the Berwick Ball with Orn Huntington, another important early gay activist in Central Ohio. The Ball began as a formal Halloween costume ball that provided a safe space to gather and enjoy drag shows for the gay community each year; over the years, it grew into an annual Halloween tradition and an important fundraiser for the AIDS movement and other charities. During the 1970s, Zimmer was also known for hosting lavish parties at his Harrisburg home. In 1989, he moved to the German Village area of Columbus where he remained active in the community. During the 1990s, Zimmer continued to perform in and out of drag and commissioned costume designer Dick Frank to make elaborate outfits. Zimmer worked for Huntington National Bank for 39 years and was a member of the Harrisburg United Methodist Church, Veterans of Foreign Wars and the German Village Society
