1. Late defoliation of ‘Chardonnay’ grapevine in subtropical highland climate
ABSTRACT Chardonnay cultivar has shown great potential of planting and development in sites above 900m of Brazilian southeast for sparkling wines production. The quality of this product is related to vineyard climate and management, since both affect the vine development and grape composition. In this study, three defoliation orientations (east, west and eas

2. Characteristics of Soils in Highland Wetlands as a Subsidy to Identifying and Setting their Limits
ABSTRACT Palustrine areas and wetlands in particular are fragile ecosystems, with high biodiversity and high ecological productivity, and they provide benefits to society. The aim of this study was to describe and classify the main soils occurring in the wetlands of the Southern Plateau of Santa Catarina, and propose criteria for identification of hydromorph

3. The Eastern Amazonic Tupi complex / O complexo Tupi da Amazônia Oriental
The main aim of this study is the analysis of the ceramic material from the Cavalo Branco site, a highland Tupi site, located in the Amazon periphery, near the Tocantins River. Comparing the results obtained from this material with those from other nearby sites it was possible to make inferences about several aspects of the eastern Amazonic Tupi. The archaeo

4. Associations between jumping spiders (Salticidae) and Bromeliaceae / Associações entre aranhas Salticidae e Bromeliaceae : historia natural, distribuição espacial e mutualismos
The understanding of the interactions between arthropods and plants has grown considerably in the last few years. Although the spiders are among the most abundant arthropod group and compose the main predator guild on vegetation, there exist very few studies involving spiders and plants. Here, we report information showing that some salticid species are stri

5. Associações entre artropodes e pequenos mamiferos silvestres de tres areas serranas do Sudeste brasileiro
t: For two years, a study on ectoparasites of small mammals was done in three highland areas ofthe Brazilian southeast (Serra da Fartura-SP, Parque Nacional do ltatiaia- RJ and Parque Nacional da Serra da Bocaina-SP). In each site a capture grid was set in the first year and a capture transect in the second year. In both years 100 Sherman s traps (tive- trap

6. Evolutionary-genetical studie of modern and archaeological samples of maize (Zea mays mays, L.) and beans (Phaseolus vulgaris, L.). / Estudo genético-evolutivo de amostras modernas e arqueológicas de milho (Zea mays mays, L.) e feijão (Phaseolus vulgaris, L.).
Seven archaeological samples of maize (Zea mays mays, Lineu), 620±60 to 990±60 years old and one sample of bean (Phaseolus vulgaris, Lineu), 301 ± 39 years old (based on C14 datation), were studied by biomolecular techniques to understand their historical origin. They were found in indigenous subterranean silos, from archaeological sites at Januária (Per

7. Estudo comparativo de flores polinizadas por beija-flores em tres comunidades da Mata Atlantica no sudeste do Brasil
This study brings an analysis of information concerning the relationships between a group of ornitophilous flowers and hummingbirds, carried out at three rainforest sites in the state of São Paulo, the sites are Caraguatatuba, a coastallowland rainforest, and two highiand rainforests: Cunha and Campos do Jordão. The study has its main focus on floristic co

8. Composição e tamanho de faunas associadas a capitulos de compostas
Composition and species richness of phytophagous insects associated with flowerheads of Compositae were investigated in samples of 70 plant species, most of them in the Astereae, Eupatorieae, Heliantheae, Senecioneae and Vernonieae. Sampled plants ranged from highly endemic species to widespread ones To investigate the effect of macrohabitat on the associate

9. Geographic Variation in Human Mitochondrial DNA from Papua New Guinea
High resolution mitochondrial DNA (mtDNA) restriction maps, consisting of an average of 370 sites per mtDNA map, were constructed for 119 people from 25 localities in Papua New Guinea (PNG). Comparison of these PNG restriction maps to published maps from Australian, Caucasian, Asian and African mtDNAs reveals that PNG has the lowest amount of mtDNA variation

10. Petrographic evidence shows that pottery exchange between the Olmec and their neighbors was two-way
Petrographic thin sections of pottery from five Formative Mexican archaeological sites show that exchanges of vessels between highland and lowland chiefly centers were reciprocal, or two-way. These analyses contradict recent claims that the Gulf Coast was the sole source of pottery carved with iconographic motifs. Those claims were based on neutron activatio

11. Association between climate variability and malaria epidemics in the East African highlands
The causes of the recent reemergence of Plasmodium falciparum epidemic malaria in the East African highlands are controversial. Regional climate changes have been invoked as a major factor; however, assessing the impact of climate in malaria resurgence is difficult due to high spatial and temporal climate variability and the lack of long-term data series on

12. Etiology of interepidemic periods of mosquito-borne disease
Dengue viruses and malaria protozoa are of increasing global concern in public health. The diseases caused by these pathogens often show regular seasonal patterns in incidence because of the sensitivity of their mosquito vectors to climate. Between years in endemic areas, however, there can be further significant variation in case numbers for which public he
