In disturbed rain forests, large, living remnant trees may be of significant importance for  postdisturbance reorganization either directly, by producing large quantities of seeds, or indirectly, by attracting vertebrate seed dispersers. In addition, remnant trees may also be important in providing a favorable microhabitat for seedlings of late-successional species. This study focused on the role of large remnant trees (&amp;gt; 40 cm dbh) in patterns of regeneration after cyclone and fire damage in the Tafua and Falealupo Rain Forest Preserves, Savai&amp;iacute;, Samoa. At Tafua, 10 large trees at each of two sites (one site burned in 1990) were investigated with regard to numbers of species and densities of plants from three different size classes at...

Tree diversity in sub-montane and lower montane primary rain forests in Central Sulawesi
Provedor de dados: 16
Autores: Culmsee, H.; Pitopang, R.
The tree diversity of sub-montane and lower montane primary forests is studied in plot-based inventories on two sites in Lore Lindu National Park, Central Sulawesi. Out of 166 species in total, 50 % are new records for Sulawesi (19 %) or the Central Sulawesi province (31 %). Species richness decreases with altitude. In the submontane forest, the highest Family Importance Values (FIV) are reached by the Lauraceae, Fagaceae, Sapotaceae, Moraceae and Euphorbiaceae. In the lower montane forest, the Fagaceae are of major importance (FIV 71.9), followed at some distance by the Myrtaceae, Elaeocarpaceae and Lauraceae. For each site, a group of important families is identified that is of minor importance or absent on the other site. The comparison of basal area...

Phylogeny and host-plant relationships of the Australian Myrtaceae leafmining moth genus Pectinivalva (Lepidoptera, Nepticulidae), with new subgenera and species
Provedor de dados: 16
Autores: Hoare, R.J.B.; Nieukerken, E.J. van.
The phylogeny of the mainly Australian nepticulid genus Pectinivalva Scoble, 1983 is investigated on the basis of morphology, and a division into three monophyletic subgenera is proposed on the basis of these results. These subgenera (Pectinivalva, Casanovula Hoare, subgen. n. and Menurella Hoare, subgen. n. ) are described and diagnosed, the described species of Pectinivalva are assigned to them, and representative new species are described in each: P. (P.) mystaconota Hoare, sp. n., P. (C.) brevipalpa Hoare, sp. n., P. (C.) minotaurus Hoare, sp. n., P. (M.) scotodes Hoare, sp. n., P. (M.) acmenae Hoare, sp. n., P.

A 15-year post evaluation of the fire effects on ant community in an area of Amazonian forest
Provedor de dados: 92
Autores: Santos,Jean C.; Delabie,Jacques H. C.; Fernandes,G. Wilson.
Fire represents an important disturbance to ant communities in areas of fire regime. Otherwise, little is known about the effects of fire on ant communities in areas of non-fire regimes, such as in the Amazonian region. We evaluated the long-term effect of fire on ant species richness in a rain forest (Bacaba Plateau) burned 15-years ago and compare our data with the data of primary unburned forest. A total of 85 ant species distributed in 21 genera and 14 tribes were collected; among them, 72 and 44 species were found on the litter and vegetation, respectively. The fire damaged forest studied supports an intermediate richness of ants when compared to a primary unburned rain forest in the same region. A comparative analysis of ant species richness showed...

A new spot-thoraxed species of Drosophila from the Atlantic Forest of southeastern Brazil (Diptera, Drosophilidae)
Provedor de dados: 92
Autores: Vilela,Carlos R.; Val,Francisca C. do.
Drosophila boraceia sp. nov. is described from a single male specimen collected at the Estação Biológica de Boracéia, Salesópolis, state of São Paulo, Brazil. At first inspection it looks like a species of Drosophila belonging to the fasciola subgroup of the repleta group, mainly because of the fasciola-like pattern of fused spots on the thorax. However, mostly due to the quite distinct structures of the male terminalia, it seems to be more similar to one ungrouped and also spot-thoraxed South American species, Drosophila atalaia Vilela &amp;amp; Sene, 1982. Illustrations of the terminalia are also provided.

Bird species diversity in the Atlantic Forest of Brazil is not explained by the Mid-domain Effect
Provedor de dados: 103
Autores: Cavarzere,Vagner; Silveira,Luís Fábio.
The Atlantic Forest is an excellent case study for the elevational diversity of birds, and some inventories along elevational gradients have been carried out in Brazil. Since none of these studies explain the patterns of species richness with elevation, we herein review all Brazilian studies on bird elevational diversity, and test a geometric constraint null model that predicts a unimodal species-altitude curve, the Mid-domain Effect (MDE). We searched for bird inventories in the literature and also analysed our own survey data using limited-radius point counts along an 800 m elevational gradient in the state of São Paulo, Brazil. We found 10 investigations of elevational diversity of Atlantic Forest birds and identified five different elevational...

Floristic overview of the epiphytic bryophytes of terra firme forests across the Amazon basin
Provedor de dados: 39
Autores: Oliveira,Sylvia Mota de; ter Steege,Hans.
Epiphytic bryophyte communities in terra firme forests of the Amazon region were investigated for the first time through standardized sampling across the Amazon basin. The sampling was carried out at nine localities, where bryophytes were collected in five height zones, from the forest floor to the canopy of eight canopy trees per locality. The sampling generated 3104 records, identifying 222 species and 39 morphospecies, within 29 families. The most common families were Lejeuneaceae (in 55%), Calymperaceae (in 8%), Leucobryaceae (in 4%) and Sematophyllaceae (in 4%). Richness and species composition did not show any geographical gradient. The bryoflora was significantly richer in the localities of Saül, in French Guiana, and Tiputini, in Ecuador, than in...

Consumption of Euterpe edulis fruit by wildlife: implications for conservation and management of the Southern Brazilian Atlantic Forest
Provedor de dados: 42
Autores: SILVA,JULIANO Z. DA; REIS,MAURÍCIO S. DOS.
Abstract: This study aimed to measure the wildlife consumption of Euterpe edulis fruit and use this data to discuss management possibilities. To estimate infructescence fruit volume consumed, collectors were installed in fruit-bearing palms. To characterize consumption from the ground, samples were placed next to fruiting palms. To identify wildlife and their activities, camera traps were installed in infructescences and on the ground. The results suggested that there was a small fruit surplus (1.8 %), and this finding indicated the possibility of a harvest to reduce food for the wildlife. However, recurrent variations in the annual fruit production (21.4 %) were also noted, and suggested that wildlife could tolerate some fruit harvesting. Thus, a harvest...

An annotated list of insect herbivores foraging on the seedlings of five forest trees in Guyana
Provedor de dados: 44
Autores: Basset,Yves; Charles,Elroy.
An annotated list of the free-living insect herbivores collected on the seedlings of five rainforest tree species of economic importance near Mabura Hill, Guyana, is presented. The host plants were Chlorocardium rodiei (Scomb.) (Lauraceae), Mora gonggrijpii (Kleinh.) Sandw. (Caesalpiniaceae), Eperua rubiginosa Miq. (Caesalpiniaceae), Pentaclethra macroloba (Willd.) Kuntze (Leguminosae,) and Catostemma fragrans Benth. (Bombacaceae). During the monitoring of approximately 10,000 seedlings at monthly intervals during two years, 27,735 insect individuals were collected representing 604 species. Leaf-chewing insects were further tested in captivity, to remove transient and non-feeding species. The most common higher taxa included Psyllidae, Cicadellinae,...

Carbon Sequestration: what really matters? - A reply to Buckeridge &amp;amp; Aidar
Provedor de dados: 49
Autores: Mattos,Eduardo Arcoverde de; Scarano,Fábio Rubio.
This is a reply to Buckeridge &amp;amp; Aidar's (2002) Point of View on the possible usefulness of GMOs (genetically modified organisms) built to increase carbon sequestration, and Plant Gene Therapy (PGT), particularly in rain forests, as future tools to reduce excessive atmospheric CO2. We argue that the alternatives to carbon sequestration they presented should not be treated as scientific or political priority, since their arguments have major ecological and socio-political flaws, such as ecological unpredictability, the existence of an already high potential for carbon sequestration by native non-manipulated plants, and the relevance of scientific and political sovereignty in regard to the global change issue.
