| ABSTRACT The immature leaves of the buriti palm (Mauritia flexuosa) are widely harvested in the municipality of Barreirinhas, Maranhão, for the production of handicrafts, which are sold to locals and tourists. The increasing demand for these artisanal goods is stimulating the emergence of an informal market for immature buriti leaves, leading to an intensification of their extraction and resulting in negative effects on local buriti palm populations and the ecosystem. Thus, the objective of the present study was to assess the environmental value of the buriti palm tree based on the maximum willingness to pay (WTP) for its conservation, using the contingent valuation method. Among the respondents, 99.74% reported that the palm species should be protected... |

| We assessed the species composition and abundance of medium and large-sized mammals in an urban forest fragment in the Brazilian Amazon, and recorded the preference of some species for particular phytophysiognomies. We placed nine transects with 20 sand plots each in three phytophysiognomies: open rainforest with a dominance of bamboos (OFB), open rainforest with palm trees (OFP), and dense rainforest (DF). We calculated species abundance as the number of records/plot.day, in a total of 2,700 plots.day. We recorded twelve mammal species; Sylvilagus brasiliensis (Linnaeus, 1758) and Dasyprocta fuliginosa (Wagler, 1831) were the most abundant. The results differed among phytophysiognomies: DF presented the highest mammal diversity, whereas the species... |

| Butia capitata is a palm tree, widely found in the Brazilian savanna. Their fruits are largely used by local communities to prepare juices, jellies and ice-creams. The main objective of this work was to determine the carotenoids profile of Butia capitata fruits and their provitamin A values. Total carotenoids content ranged from 11.1 to 43.9 μg.g-1; β-carotene was the predominant carotenoid (5.2-22.8 μg.g-1), followed by γ-carotene, phytoene, phytofluene, ζ-carotene, α-cryptoxanthin (or zeinoxanthin) and α-carotene. Provitamin A values varied from 50 to 200 RAE.100g-1. This result suggests that B. capitata pulp may be a good source of β-carotene and provitamin A. |

| Butia capitata (Mart.) Becc., commonly known as jelly palm, is a palm tree native to the Cerrado biome. It is considered an endangered species owing to intensive extractive exploitation of its fruits, with slow and uneven seminiferous propagation as an aggravating factor. Thereby, there are some bottlenecks related to jelly palm seedling production that needs to be optimized. Light quality and intensity is very important to seedling production, as it controls the metabolism of plants and consequently their growth and development. Thus, the aim of this work is to evaluate the effect of shade nets on the growth and physiological aspects of jelly palm seedlings. The experimental design was completely randomized, with five treatments, ten replicates and eight... |

| Abstract The Acrocomia totai palm can be found in areas of Cerrado and Pantanal in Brazil, Argentina, Bolivia and Paraguay. Its fruits are used by traditional and rural communities for subsistence or income source. Given the relevance of this genetic resource, we assessed the morphological and agronomic characters and estimated the population density in two physiognomies of the Pantanal. We found variation in all analyzed characters, such as the density of spines on the stipe, coloration of leaves, epicarp and mesocarp. The average number of fruits per bunch was 392.30±134.53, fresh mass (g) of the whole fruit of 15.50±3.87 and, the mesocarp oil content (%) of 14.94±8.06. The population density varied between 48 pls.ha-1 in area of shrubby grassland to... |

| The occurrence of the tachinid parasitoid Billaea rhynchophorae (Blanchard) on larvae of the palm weevil Rhynchophorus palmarum (L.) was evaluated in plantations of piassava palm (Attalea funifera Mart.) and African oil palm (Elaeis guineensis Jacquin), in southeastern Bahia, Brazil. The monthly percentages of parasitism were evaluated during 13 months, from November 2000 to November 2001, based on the comparison between the number of parasitized and non-parasitized cocoons of R. palmarum. Mean parasitism was 40% and ranged from 50% in November 2000 to 18% in July 2001. While there is no method of mass reproduction of the parasitoid, a simple management practice is recommended, in order to preserve its beneficial effects in palm plantations. |

| The oil palm Elaeis guineensis is usually attacked by pests, particularly, defoliating caterpillars. Between 2004 and 2006 a stinkbug predator (Asopinae) was registered preying on caterpillars of Brassolis sophorae L., Opsiphanes invirae Hübner (Lepidoptera: Nymphalidae) and Sibine spp. (Lepidoptera: Limacodidae), reducing their populations in commercial oil palm plantations in the State of Pará, Brazil. Specimens of the natural enemy were collected, mounted, and identified as Alcaeorrhynchus grandis (Dallas) (Hemiptera: Pentatomidae), corresponding to the first report of the occurrence of this stinkbug attacking defoliating caterpillars of oil palm in Brazil. |
