The cost of quinine Cinchona pubescens control on Santa Cruz Island, Galapagos - Buddenhagen, Chris; Yanez, Patricio
We analyse the cost of controlling the invasive quinine tree Cinchona pubescens Vahl in the highlands of Santa Cruz Island, Galapagos. Control costs in ten 400 m2 plots formed the basis for estimating the cost of control over the whole island. In the plots, densities were 2100–24,000 stems/ha (stems >150 cm tall) and 55,000–138,000 stems/ha (all size classes combined). Control involved uprooting small plants, and applying of a mix of metsulfuron methyl and picloram to
cut stumps or to machete cuts in the bark of larger trees. These methods are presently used by Galapagos National
Park field crews to control quinine. Costs...
Local distribution patterns of Opuntia echios echios, Bursera graveolens and Scalesia crockeri on Santa Cruz Island, Galapagos - Runkle, James R.; Runkle, William A.
We mapped stems of three plant species in a 2.36 ha plot in the arid zone near the coast of eastern Santa Cruz Island,
Galapagos, Ecuador, to determine factors influencing their local distribution. The three species were Opuntia echios var. echios (Cactaceae), a large cactus, Bursera graveolens (Burseraceae), a small tree that dominates dry woodland near the coast, and the shrub Scalesia crockeri (Asteraceae). In our plot, Opuntia was most abundant near the coast, while Bursera and Scalesia increased in density inland and with increased relief. Scalesia also increased in density with increases in Bursera and decreases in other woody plants...
Arthropods in the Charles Darwin Research Station herbarium,
Galapagos, during 1999–20 - Jaramillo, Patricia; Reyes, Diego; Yanez, Patricio
This paper describes the arthropods found in the Charles Darwin Research Station herbarium from 1999 to 2001.
Nineteen species were found from four classes. Most individuals were from the families Formicidae (Paratrechina
longicornis with 777 individuals), Porcellidae (134), Drosophilidae (43) and Corinnidae (38). CDF Contribution Number 1011.
Viability of seeds in food products proposed for field trips in Galapagos - Jaramillo, Patricia; Bassantes, Joselyn; Tye, Alan
Seeds of 14 plant species extracted from food products proposed for field trips in Galapagos were tested for viability.
Strawberry Fragaria ananasa and Blackberry Rubus glaucus jams (Snob and Gustadina brands) contained no viable
seeds. Schullo brand granola contained inviable Sesame Sesamum indicum seed, but Sesame in granolas prepared in
Galapagos was viable. Sesame seed in bread was viable but Flax Linum usitatissimum seed in bread was not. Brown Rice
Oryza sativa and Sunflower seeds Helianthus annuus were both viable. Fresh Apple Malus domestica, Naranjilla Solanum
quitoense, Cucumber Cucumis sativus, Pineapple Ananas comosus, Pear Pyrus communis, Bell Pepper Capsicum annuum,
Tomato Solanum lycopersicum, Grape Vinis vinifera...
