1. Delimitação de espécies e diversidade genética no complexo Cattleya coccinea Lindl. e C. mantiqueirae (Fowlie) van den Berg (Orchidaceae) baseada em marcadores moleculares ISSR / Species Delimitation and genetic diversity in Cattleya coccinea Lindl. and C. mantiqueirae (Fowlie) van den Berg complex (Orchidaceae) based on ISSR molecular makers
As orquídeas são a maior família das plantas monocotiledôneas, sendo o Brasil um dos países contém grande diversidade de espécies. As orquídeas são, em sua maioria, alógamas e possuem mecanismos sofisticados para evitar a autopolinização. Os insetos são os agentes polinizadores mais comuns, mas também podem ser polinizados por aves como beija-f

2. Ecologia de Methylobacterium spp. na planta hospedeira / Methylobacterium spp. ecology in the host plant
The genus Methylobacterium, constituted by PPFMs - pink-pigmented facultative methylotrophic, are able to fix nitrogen, nodule the host plant, produce cytokines and enzymes involved in induction of systemic resistance such as pectinase and cellulase, inducing plant growth. Methylobacterium sp. has been described as endophyte or epiphyte in different host pla

3. Relacionamento entre anfíbios anuros e bromélias da restinga de Regência, Linhares, Espírito Santo, Brasil
Some anuran amphibians use the bromeliads during the entire life cycle and others only as diurnal shelter. At the sandy coastal plain of Linhares, State of Espírito Santo, Southeastern Brazil, 676 bromeliads were examined, of which 303 of Aechmea blanchetiana (Baker) L. B. Smith., 1955, 287 of Aechmea nudicaulis (L.) Griseb., 1864, and 86 of Vrisea procera

4. Florística e estrutura do componente epifítico vascular na mata da reserva da Cidade Universitária "Armando de Salles Oliveira", São Paulo, SP. / Floristics and structure of the vascular epiphytic component in the forest of the reserve of the Cidade Universitária "Armando de Salles Oliveira", São Paulo, SP.
This work assesses floristics and structure of epiphytes, here defined as vascular plants usually found living on others, without parasitizing them, during at least a part of their life cycles. The study site, the reserve of the Cidade Universitária "Armando de Salles Oliveira" (nearly 46o43W, 23o33S), in São Paulo-SP (Brazil), is a secondary forested

5. Mode of Filamentous Growth of Leucothrix mucor in Pure Culture and in Nature, as Studied by Tritiated Thymidine Autoradiography
Mode of growth of Leucothrix mucor filaments was measured by autoradiography with tritiated thymidine. Studies were performed on L. mucor in pure cultures in free suspension, as an epiphyte of pure cultures of the red alga Antithamnion sarniense, and as an epiphyte of red algae in the sea. Statistical analyses of the distribution of growing cells was done by

6. Active Uptake of Amino Acids by Leaves of an Epiphytic Vascular Plant, Tillandsia paucifolia (Bromeliaceae) 1
Specialized epidermal trichomes on the leaves of the epiphyte, Tillandsia paucifolia (Bromeliaceae) accumulate amino acids from solution. Simultaneous net uptake of 17 amino acids was determined using high performance liquid chromatography. Uptake occurs against concentration gradients at least as high as 104.

7. Direct Comparison of Phosphate Uptake by Adnate and Loosely Attached Microalgae within an Intact Biofilm Matrix
We report a direct comparison of phosphate uptake by adnate and loosely attached microalgae in an intact biofilm matrix, with resolution at the level of individual cells. Track scanning electron microscope autoradiography enabled assay of [33P]phosphate uptake from the overlying water by adnate algae left undisturbed on mature leaves of the macrophyte Potamo

8. Bacteria in the Leaf Ecosystem with Emphasis on Pseudomonas syringae—a Pathogen, Ice Nucleus, and Epiphyte
The extremely large number of leaves produced by terrestrial and aquatic plants provide habitats for colonization by a diversity of microorganisms. This review focuses on the bacterial component of leaf microbial communities, with emphasis on Pseudomonas syringae—a species that participates in leaf ecosystems as a pathogen, ice nucleus, and epiphyte. Among

9. Factors Affecting the Contribution by Epiphytic Algae to the Primary Productivity of an Oligotrophic Freshwater Lake1
A diatom-dominated population of epiphytic algae was studied in an oligotrophic lake to determine the factors which limit epiphyte growth and to measure their contribution to primary productivity. Algae were collected from plants growing at four sites in Lake George, N.Y., during the spring, summer, and fall of 1974. Samples were taken from 3 m, correspondin

10. Colonization of a Submersed Aquatic Plant, Eurasian Water Milfoil (Myriophyllum spicatum), by Fungi under Controlled Conditions
A laboratory assay to assess colonization of a submersed aquatic plant, Eurasian water milfoil (Myriophyllum spicatum), by fungi was developed and used to evaluate the colonization potential of Colletotrichum gloeosporioides, Acremonium curvulum, Cladosporium herbarum, Aureobasidium pullulans, a Paecilomyces sp., and an unidentified sterile, septate fungus.

11. Attachment of the Yeast Rhodosporidium toruloides Is Mediated by Adhesives Localized at Sites of Bud Cell Development
The basidiomycetous yeast Rhodosporidium toruloides (anamorph, Rhodotorula glutinis) is a common phylloplane epiphyte with biocontrol potential. To understand how R. toruloides adheres to plant surfaces, we obtained nonadherent fungal mutants after chemical mutagenesis with methane-sulfonic acid ethyl ester. Sixteen attachment-minus (Att−) mutants were ide

12. Fitness of Salmonella enterica serovar Thompson in the Cilantro Phyllosphere
The epiphytic fitness of Salmonella enterica was assessed on cilantro plants by using a strain of S. enterica serovar Thompson that was linked to an outbreak resulting from cilantro. Salmonella serovar Thompson had the ability to colonize the surface of cilantro leaves, where it was detected by confocal laser scanning microscopy (CLSM) at high densities on t
