Prueba de dos insecticidas sistémicos en dos formas de aplicación, en el control del tórsalo (Dermatobia hominis) Lin. Jr

Con el objeto de determinar cuál es el insecticida más efectivo en el control del tórsalo y la mejor forma de aplicación, se llevo a cabo un experimento en el Departamento de Boaco en el lapso comprendido de Julio a Diciembre de 1967. En cada finca se utilizaron cuarenta animales. Los insecticidas aplicados fueron: Ruelene 25 E en dosis de diez y siete miligramos por kilogramo de peso vivo y Neguvón en dosis de cincuenta miligramos por kilogramo de peso vivo. Los insecticidas se aplicaron en la forma siguiente: Ruelene 25 E vertido Ruelene 25 E solución Neguvón vertido Neguvón solución Se efectuaron recuentos de parásitos al principio del experimento y a los tres días y a los ocho días después de la aplicación de los insecticidas. El diseño experimental usado fue de bloques al azar con repeticiones y análisis dentro de las fincas. Los dos insecticidas y sus formas de aplicación estadísticamente tuvieron la misma efectividad, con porcentajes de control similares. el ruelene 25 E fue el insecticida de menor costo, en las dos formas de aplicación. Durante el experimento no se observaron efectos tóxicos en ningún animal. Se observó que el poder residual del Ruelene 25 E fue mayor que el del Neguvón.

Ground-water resources of the Stuart area, Martin County, Florida

Because the Stuart area is, at times, surrounded on three sides by saline water, the underlying fresh-water aquifer is vulnerable to salt-water encroachment. With progressively larger withdrawals of ground water for public and private supplies, the possibility of salt-water contamination of freshwater supplies is increased. (PDF contains 51 pages.)

Biodiversity study of Southern Biscayne Bay and Card Sound 1968-1973

A multi-disciplinary investigation was conducted in southern Biscayne Bay and Card Sound from 1968 to 1973. The purpose of the investigation was to conduct an integrated study of the ecology of southern Biscayne Bay with special emphasis on the effects of the heated effluent from the Turkey Point fossil fuel power plant, and to predict the impact of additional effluent from the planned conversion of the plant to nuclear fuel. The results of this investigation have been discussed in numerous publications. This report contains the unpublished biology data that resulted from the investigation. (PDF contains 44 pages)

Charles M. Breder, Jr.: Palmetto Key, 1942

Charles M. Breder and his wife Ethel spent part of the summer of 1942 at the Palmetto Key field station, known today as Cabbage Key, on the west coast of Florida south of Charlotte Harbor. The Palmetto Key field station began in 1938 and ended in 1942 because of World War II. His Palmetto Key diary ran for 95 pages of notes, tables, diagrams, drawings, lists, and business records and this report presents a variety of fascinating entries. Diaries from other years all bear Breder's style of discipline, curiosity, humor, and speculations on nature. The diary was transcribed as part of the Coastal Estuarine Data/Document Rescue and Archeology effort for South Florida. (PDF contaons 24 pages)

Charles M. Breder, Jr.: Hypothetical considerations, 1931-1937

Charles M. Breder Jr. “hypothesis” diary is a deviation from the field diaries that form part of the Breder collection housed at the Arthur Vining Davis Library, Mote Marine Laboratory. There are no notes or observations from specific scientific expeditions in the document. Instead, the contents provide an insight into the early meticulous scientific thoughts of this biologist, and how he examines and develops these ideas. It is apparent that among Dr. Breder’s passions was his continual search for knowledge about questions that still besieged many scientists. Topics discussed include symmetry, origin of the atmosphere, origin of life, mechanical analogies of organisms, aquaria as an organism, astrobiology, entropy, evolution of species, and other topics. The diary was transcribed as part of the Coastal Estuarine Data/Document Rescue and Archeology effort for South Florida. (PDF contains 33 pages)
