1. Effectiveness of Telemedicine in Reducing Hospitalizations in Patients Discharged from the Hospital Due to Heart Failure: A Randomized Clinical Trial Protocol
Abstract Fundament: Telemedicine for follow-up in heart failure (HF) patients is effective in reducing hospitalizations, total and cardiovascular mortality. However, few studies were conducted in low and middle income, where lower access to technology and illiteracy could impact the results. Objective: To assess the effectiveness of associating telemedicin

2. Adventitious rooting of cultivars and clonal selections of Prunus spp. rootstock under intermittent mist system
ABSTRACT To reduce peach tree losses due the Peach Tree Short Life (PTSL), the main research line in Brazil is to select tolerant rootstock and perpetuate it by cloning methods. The objective was to evaluate adventitious rooting capacity of softwood cuttings of three cultivars and several clonal rootstock selections of Prunus spp., under intermittent mist s

3. SHADING AS A DETERMINANT FACTOR FOR THE SURVIVAL AND GROWTH OF Cabralea canjerana IN SOUTHERN BRAZIL
ABSTRACT Plantations with native tree species, which emphasize biodiversity conservation, may not succeed because of a lack of forestry knowledge about the native species. Cabralea canjerana is an important tree species, which is rarely present in area restoration programs because of the difficulty in establishing it in plantations. Despite this, the species

4. Closing the Snack Bar: Developing Methods for Jackfruit Tree (Artocarpus heterophyllus Lamk.) Control in Brazil
ABSTRACT There are several techniques for the control and removal of invasive species that can be applied, and there is a demand among restoration practitioners for plant control methods. This study compared two methods for the control of jackfruit tree: mechanical method of trunk girdling and chemical method of herbicide injection into the trunk. It was eva

5. Efectos del fuego en el arbolado de un bosque tropical de pino y en el de una selva baja caducifolia en Villaflores, Chiapas
Abstract It is expected an increase of forest fires world-wide because of global warming. So is important the study of fire ecology and fire effects in different ecosystems. In Villaflores, Chiapas, Mexico, are conducted efforts towards the integral fire management. There was studied a Pinus oocarpa Schiede forest, as well as a tropical dry forest, affected

6. CARBON STOCK GROWTH IN A SECONDARY ATLANTIC FOREST
RESUMO As florestas secundárias de Mata Atlântica possuem um papel importante no contexto das mudanças climáticas por atuarem como sumidouro de carbono da atmosfera. Entretanto, essas florestas podem se transformar em fonte de carbono com o aumento da mortalidade de árvores. O conhecimento dessa mudança é possível mediante inventários florestais con

7. Growth of Tree Species in Coexistence with Palisade Grass Urochloa brizantha (Hochst. ex A. Rich.) Stapf CV. Marandu
RESUMO: Avaliou-se neste trabalho o efeito da presença do capim-braquiarão (Urochloa brizantha) sobre o crescimento de cinco espécies arbóreas do bioma Mata Atlântica, em Seropédica-RJ. O estudo abrangeu cinco experimentos em delineamento inteiramente casualizado. Em cada experimento, testou-se em vasos o efeito da gramínea sobre o crescimento das esp

8. Plant-canopy Effects on Natural Regeneration in Sites Under Restoration: Do Tree Species Matter?
ABSTRACT How does species choice influence ecological restoration outcomes? In order to answer this question, the goal of this study was to assess the community structure and species richness of natural regeneration beneath the canopy of four native species from the Atlantic Forest (Guarea guidonia (L.) Sleumer; Inga edulis Mart; Nectandra membranacea (SW) G

9. Temporal Behavior of Tree Communities in Different Soil Classes
ABSTRACT The objective of this work was to evaluate if the soil heterogeneity expressed by the different soil classes would condition tree communities with different dynamic behaviors. The data were collected from 25 plots sized 20 × 20 (400 m²), 10 of them with Inceptisols, 9 with Ultisols, 5 with Entisols B and 1 with Entisols A. All individuals with DBH

10. Controlled-Release Fertilizer on Growth of Melanoxylon brauna Schott Seedlings
ABSTRACT Melanoxylon brauna is a tree species native to the Atlantic Forest of high ecological and economic value. The objective of this study was to evaluate the growth and nutritional status of seedlings of two Melanoxylon brauna cultivars grown in substrate with different controlled-release fertilizer doses (CRF). The experiment was arranged in a randomiz

11. Post-fire recovery of a dense ombrophylous forest in Amazon
Abstract: The fires that occur in the Amazon are as damaging as the deforestation is. There is a need for further long-term studies on dynamics of tree communities in forests affected by fires. In the present study we evaluated the dynamics of tree species, before and after an accidental fire that occurred in 1997 in an experimental area of terra firme fores

12. Expansão da vegetação arbustivo-arbórea em áreas abertas alto-montanas adjacentes a fragmentos florestais, no Planalto Sul Catarinense
Resumo O objetivo deste estudo foi conhecer os padrões demográficos da regeneração natural do componente arbustivo-arbóreo e determinar se esses são influenciados pelas variáveis ambientais, em três áreas abertas em regeneração natural (diâmetro na altura do peito < 5 cm), em contato com fragmentos florestais de Floresta Ombrófila Mista Alto-Mon
