The Enigmatic Spelaeorhynchidae Oudemans, 1902 (Acari: Mesostigmata) Blood-Feeding Ectoparasites Infesting Neotropical Bats, with Catalog and Notes on a Collection from the Manú Biosphere Reserve in Peru

A survey of ectoparasites associated with bats collected along an elevational transect in the Manú Biosphere Reserve, Peru, includes specimens of two species of an unusual and rarely collected family of parasitic mites, the Spelaeorhynchidae Oudemans, and reveals information on the natural occurrence of these infections. In lowland rainforest (450–1,000 m) along the Rio Alto Madre de Dios, Spelaeorhynchus soaresi Peracchi was recorded exclusively infecting two species of frugivorous Carollia, C. brevicauda and C. perspicillata. At higher elevations in the mountains and cloud forests, Spelaeorhynchus praecursor Neumann exclusively infected two species of nectarivorous Anoura, A. cultrata and A. geoffroyi. The consistency of both altitudinal and host distributional limits between sampling periods suggests that the true focus of infection may be sustained in certain habituated, long-term roosting sites. This valuable spelaeorhynchid survey collection (slides and vials) is available for further study at the following repositories: the Harold W. Manter Laboratory of Parasitology, University of Nebraska–Lincoln, and the Field Museum of Natural History, Chicago

Stand Analysis of an Invading Firetree (Myrica faya Aiton) Population, Hawaii

Since 1971, the exotic firetree (Myricafaya) has been invading a native ohia tree (Metrosideros collina subsp. polymorpha Rock) habitat in the 1959 Kilauea Iki devastation area, Hawaii Volcanoes National Park. Ninetysix trees of the invading population were analyzed as to structural and fruiting characteristics. Data were collected from two permanent transects that were designed to provide for continued study of the fire tree and ohia community. Initial findings reveal that the present firetree spread depends on an outside seed source, and successful seedling establishment is dependent on favorable microhabitat conditions beneath ohia trees. As yet, no competitive replacement of ohia trees by fire trees has been observed. On the contrary, firetrees over 2 m tall that had grown up and into ohia tree crowns were exhibiting poor vigor. Additionally, there is a high positive correlation between fire tree loss of vigor and diameter increase beyond 4-5 em. Preliminary observations suggest that fire tree seed dispersal depends on birds, primarily, the exotic Japanese white-eye (Zosterops japonica)
