Roosting habits of bats affect their parasitism by bat flies (Diptera: Streblidae)
Journal of Tropical Ecology - Tập 23 Số 2 - Trang 177-189 - 2007
Bruce D. Patterson, Carl W. Dick, Katharina Dittmar
The Smithsonian Venezuela Project (SVP) conducted extensive surveys of mammals and ectoparasites in the 1960s. The 25 238 individuals and 130 species of bat collected by SVP hosted 36 663 streblid bat flies, representing 116 species of these ectoparasitic dipterans. Roosts of bat species differ in durability and protection, and bat flies separate from the host to pupate in the roost. We pr...... hiện toàn bộ
Sex biases in parasitism of neotropical bats by bat flies (Diptera: Streblidae)
Journal of Tropical Ecology - Tập 24 Số 4 - Trang 387-396 - 2008
Bruce D. Patterson, Carl W. Dick, Katharina Dittmar
AbstractWe describe levels of parasitism of ectoparasitic bat flies (Hippoboscoidea: Streblidae) on male and female bats from an extensive Neotropical survey. The collection resulted from coordinated vertebrate-parasite surveys undertaken by the Smithsonian Venezuelan Project (SVP) from 1965–1968, which sexed 24 978 bats of 130 species. Streblid parasites were reco...... hiện toàn bộ
Intraspecific patterns of ectoparasite abundances on Paraguayan bats: effects of host sex and body size
Journal of Tropical Ecology - Tập 24 Số 1 - Trang 75-83 - 2008
Steven J. Presley, Michael R. Willig
Abstract:Although levels of parasitism can vary greatly among individual bats of the same species, little is known about the characteristics of hosts that affect such variation. Bats were captured via mist nets from June 1995 to July 1997 from 28 localities throughout Paraguay. Over 17 500 ectoparasites were collected from 2909 bats; however, analyses of ectoparasi...... hiện toàn bộ
General flowering in the climax rain forests of South-east Asia
Journal of Tropical Ecology - Tập 1 Số 3 - Trang 225-240 - 1985
S. Appanah
ABSTRACTThe general flowering of lowland dipterocarp forests of South-east Asia is a unique phenomenon that occurs intermittently, sometimes many years apart, and may be widespread throughout the region or sporadic. During a general flowering a very large number of tree families, including the well-known Dipterocarpaceae, flower and fruit exceptionally heavily. The...... hiện toàn bộ
Partitioning of the understorey light environment by two Amazonian treelets
Journal of Tropical Ecology - Tập 15 Số 6 - Trang 751-763 - 1999
John Terborgh, Jeffrey Mathews
Primary tropical forests comprise a mosaic of mature, gap and building phase patches, resulting in great spatial variation in the distribution of foliage. Light may consequently penetrate into the forest interior over a wide range of angles. It thus seems possible that understorey tree species might be adapted for distinct understorey light conditions. At the Cocha Cashu Biological Station...... hiện toàn bộ
Effects of artificial defoliation on growth, reproduction and leaf chemistry of the mangrove Kandelia candel
Journal of Tropical Ecology - Tập 19 Số 4 - Trang 397-406 - 2003
You-Gui Tong, Shing Yip Lee, Brian Morton
The effects of defoliation on leaf and propagule production, and leaf chemistry of the mangrove Kandelia candel (L.) Druce were evaluated in a manipulative experiment in Hong Kong. Artificial defoliation of leaf lamina at 50% of the length of midrib resulted in significant reduction in leaf, twig and propagule production, and size of the latter. Through the n...... hiện toàn bộ
Herbivory as an ecological process in a Kandelia candel (Rhizophoraceae) mangal in Hong Kong
Journal of Tropical Ecology - Tập 7 Số 3 - Trang 337-348 - 1991
Shing Yip Lee
ABSTRACTNatural levels and consequences of insect herbivory were studied for a Kandelia candel (Rhizophoraceae) dominated mangal at the Mai Po Marshes, Hong Kong. Grazing insects (mainly lepidopteran larvae) consumed, on average, 10.3% of the leaf area on K. candel, with >90% of the leaves suffering <30% l...... hiện toàn bộ
Control of Avicennia germinans recruitment and survival by Junonia evarete larvae in a disturbed mangrove forest in Colombia
Journal of Tropical Ecology - Tập 15 Số 6 - Trang 791-805 - 1999
Carola Elster, Laura Perdomo, Jaime Polanía, Marie-Luise Schnetter
In the Ciénaga Grande de Santa Marta, a brackish lagoon system on the Caribbean coast of Colombia, about 60% of the mangrove forests died from hypersalinization. The die-back was first encountered in 1964 and mass mortality started in the late 1960s. Although efforts are being made to reestablish the destroyed areas, regeneration is slow, which may be partly due to Junonia eva...... hiện toàn bộ
Spatial variation of throughfall volume in an old-growth tropical wet forest, Costa Rica
Journal of Tropical Ecology - Tập 18 Số 3 - Trang 397-407 - 2002
Henry W. Loescher, Jennifer S. Powers, Steven F. Oberbauer
Throughfall volume and interception of bulk precipitation events were measured during individual rain events of differing magnitudes in a primary wet tropical forest at La Selva Biological Station, Costa Rica. The relationship between canopy structure and throughfall were examined to identify key sources of spatial variation. Geostatistical analyses were also used to examine the spatial va...... hiện toàn bộ
Influence of soil, topography and substrates on differences in wood decomposition between one-hectare plots in lowland tropical moist forest in Central Amazonia
Journal of Tropical Ecology - Tập 25 Số 6 - Trang 649-656 - 2009
José Júlio de Toledo, William E. Magnusson, Carolina V. Castilho
Abstract:Understanding how wood decomposition varies spatially at the mesoscale (between 1-ha plots) may improve carbon flux estimates in Amazonian forests. An experiment was carried out to test the influence of soil, slope, above-ground tree live biomass (biomass), fine-litter mass and characteristics of neighbouring trees on the variation of wood decomposition be...... hiện toàn bộ
