Roosting habits of bats affect their parasitism by bat flies (Diptera: Streblidae)
Journal of Tropical Ecology - Tập 23 Số 2 - Trang 177-189 - 2007
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
predicted ...
Sex biases in parasitism of neotropical bats by bat flies (Diptera: Streblidae)
Journal of Tropical Ecology - Tập 24 Số 4 - Trang 387-396 - 2008
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 recovered from
6935 individuals of 87...
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
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 ectoparasite abundance were restricted to
m...
General flowering in the climax rain forests of South-east Asia
Journal of Tropical Ecology - Tập 1 Số 3 - Trang 225-240 - 1985
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 huge pulse of
flowering is echoe...
Partitioning of the understorey light environment by two Amazonian treelets
Journal of Tropical Ecology - Tập 15 Số 6 - Trang 751-763 - 1999
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
in Madr...
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
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 negative effects on propagule
number and...
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
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% loss.
Natural median leaf longevity was significantly different between winter and
summer-expo...
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
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
evarete caterpillars def...
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
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
variation ...
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
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 between 1-ha plots in
four species ...
