1. Diversidade e estrutura da comunidade bacteriana associada às armadilhas da planta carnívora Utricularia gibba (Lentibulariaceae) e ao ambiente aquático. / Diversity and structure of bacterial communities associated to the traps of the carnivorous plant Utricularia gibba (Lentibulariaceae) and aquatic environment.
A diversidade microbiana em ambientes aquáticos e sua associação com plantas carnívoras ainda é pouco estudada. Assim, a comunidade bacteriana da planta carnívora Utricularia gibba e do seu meio aquático foi avaliada por meio do seqüenciamento em larga escala (454 Roche) de uma biblioteca do gene 16S rRNA. Os resultados indicaram que a comunidade bac

2. The abiotic environment of Heliamphora nutans (Sarraceniaceae): pedological and microclimatic observations on Roraima Tepui
The aim of this study was the study of the abiotic environment of the carnivorous pitcher plant Heliamphora nutans (Sarraceniaceae), including the microclimate and the geochemistry of the soil of the growing sites on Roraima Tepui and discuss their relevance within the recent model of carnivorous plant ecology. The soil was peaty and low in nutrients. The mi

3. The loss of leaf and its relation to genus Ectatomma (Formicidae:Ecatomminae) in a cerrado community / A perda de área foliar e sua relação com o gênero Ectatomma (Formicidae: Ectatomminae) em uma comunidade de cerrado
The loss of leaf area, mostly resulting from the action of herbivores is one of the factors that regulate the reproductive success of a plant and indirectly to all consumers connected to the community. Most studies of herbivory and leaf loss are punctual, i.e., refer to one or a few plant species. In the cerrado, a tropical savanna in Brazil, the largest sav

4. Interações entre Pachycondyla striata e Odontomachus chelifer (Formicidae, Ponerinae) e diasporos em tres fisionomias florestais da Mata Atlantica / Interactions between Pachycondyla striata and Odontomachus chelifer (Formicidae, Ponerinae), and diaspores in three landscapes at Mata Atlantica
The present study investigated the spatial variation in interactions involving the ponerine ants Pachycondyla striata and Odontomachus chelifer and nonmyrmecochorous diaspores. The study was carried out at the three continuous forests formations in the Brazilian Atlantic forest: Restinga forest (2-3 m above sea level), Lowland forest (05-30 m above sea level

6. Tree shrew lavatories: a novel nitrogen sequestration strategy in a tropical pitcher plant
Nepenthes pitcher plants are typically carnivorous, producing pitchers with varying combinations of epicuticular wax crystals, viscoelastic fluids and slippery peristomes to trap arthropod prey, especially ants. However, ant densities are low in tropical montane habitats, thereby limiting the potential benefits of the carnivorous syndrome. Nepenthes lowii, a

7. Nitrogen availability alters the expression of carnivory in the northern pitcher plant, Sarracenia purpurea
Atmospheric transport and deposition of nutrients, especially nitrogen, is a global environmental problem with well-documented consequences for ecosystem dynamics. However, monitoring nitrogen deposition is relatively expensive, monitoring stations are widely spaced, and estimates and predicted impacts of nitrogen deposition are currently derived from spatia

8. Signal transduction in the carnivorous plant Sarracenia purpurea. Regulation of secretory hydrolase expression during development and in response to resources.
Carnivory in plants has developed as an evolutionary adaptation to nutrient-poor environments. A significant investment of the resources of a carnivorous plant is committed to producing the traps, attractants, and digestive enzymes needed for the carnivory. The cost:benefit ratio of carnivory can be improved by either maximizing the prey capture rate or by r

9. Nectar, not colour, may lure insects to their death
We experimentally demonstrate in the field that prey of the carnivorous plant Sarracenia purpurea are attracted to sugar, not to colour. Prey capture (either all taxa summed or individual common taxa considered separately) was not associated with total red area or patterning on pitchers of living pitcher plants. We separated effects of nectar availability an

10. Adaptive evolution of cytochrome c oxidase: Infrastructure for a carnivorous plant radiation
Much recent attention in the study of adaptation of organismal form has centered on developmental regulation. As such, the highly conserved respiratory machinery of eukaryotic cells might seem an unlikely target for selection supporting novel morphologies. We demonstrate that a dramatic molecular evolutionary rate increase in subunit I of cytochrome c oxidas

11. Combined Transcript and Metabolite Analysis Reveals Genes Involved in Spider Mite Induced Volatile Formation in Cucumber Plants1
Many plants have an indirect defense against herbivores by emitting volatiles that attract carnivorous enemies of the herbivores. In cucumber (Cucumis sativus) the production of carnivore attractants can be induced by herbivory or jasmonic acid spraying. From the leaves of cucumber plants with and without spider mite infestation, two subtractive cDNA librari
