A contingent valuation study of buriti ( Mauritia flexuosa L.f.) in the main region of production in Brazil: is environmental conservation a collective responsibility? Acta Botanica
Vieira,Irlaine R.; Oliveira,Jefferson S.; Santos,Kelly P. P.; Silva,Geisiane O.; Vieira,Fábio J.; Barros,Roseli F. M..
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...

Anatomical and histochemical comparison of the primary and adventitious roots of Attalea microcarpa (Arecaceae) at the initial growth stage Acta Amazonica
CORRÊA,Marcos Melo; ARAÚJO,Maria Gracimar Pacheco de; MENDONÇA,Maria Sílvia de.
ABSTRACT We describe the anatomical structure of roots originating from the apocole of Attalea microcarpa compared to the primary root, by means of usual methods for optical microscopy. The adventitious roots are differentiated in the apocole associated to vascular bundles, and can remain as a single structure or branch. They have the basic root structure characteristic of Arecoideae palms, without schizogenous spaces, which are observed in the primary root, in addition to few air spaces. Mucilages, starch and proteins were present in both types of roots. Adventitious roots of the apocole are described for the first time in Arecaceae.

Coconut genome size determined by flow cytometry: tall versus dwarf types. Repositório Alice
FREITAS NETO, M.; PEREIRA, T. N. S.; GERONIMO, I. G. C.; AZEVEDO, A. O. N.; RAMOS, S. R. R.; PEREIRA, M. G..
Coconuts (Cocos nucifera L.) are tropical palm trees that are classified into Tall and Dwarf types based on height, and both types are diploid (2n = 2x = 32 chromosomes). The reproduction mode is autogamous for Dwarf types and allogamous for Tall types. One hypothesis for the origin of the Dwarf coconut suggests that it is a Tall variant that resulted from either mutation or inbreeding, and differences in genome size between the two types would support this hypothesis. In this study, we estimated the genome sizes of 14 coconut accessions (eight Tall and six Dwarf types) using flow cytometry. Nuclei were extracted from leaf discs and stained with propidium iodide, and Pisum sativum (2C = 9.07 pg DNA) was used as an internal standard. Histograms with good...

Diversity and habitat preference of medium and large-sized mammals in an urban forest fragment of southwestern Amazon Iheringia, Sér. Zool.
Borges,Luiz H. M.; Calouro,Armando. M.; Botelho,André L. M.; Silveira,Marcos.
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...

Fruits of Butia capitata (Mart.) Becc as good sources of β -carotene and provitamina Rev. Bras. Frutic.
Faria,Juliana Pereira; Siqueira,Egle M. A; Vieira,Roberto Fontes; Agostini-Costa,Tânia da Silveira.
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.

Genetic variation detected by RAPD markers in natural populations of babassu palm (Attalea speciosa Mart.). Repositório Alice
SANTOS, M. F.; SILVA, K. J. D. e; CARVALHAES, M. A.; LIMA, P. S. da C..
The purpose of this study was to analyze the effects of management on the genetic structure of natural populations of Attalea speciosa in the State of Piauí, Brazil, using random-amplified polymorphic DNA (RAPD) markers. Three babassu populations under different management systems were selected. Polymerase chain reactions were performed for 20 RAPD primers. A total of 146 bands were generated, 141 of which were polymorphic (96.58%), with a variation of 4 and 12 loci and an average of 7 bands per primer. A dendrogram revealed a clear separation between the three populations (0.57). Data reliability and node consistency were verified by bootstrap values and the cophenetic correlation coefficient (88.15%). Coefficients of similarity between pairs of genotypes...

Growth and physiology of jelly palm (Butia capitata) grown under colored shade nets Agronomy
Costa, Irton de Jesus Silva; Costa, Bárbara Nogueira Souza; Assis, Franscinely Aparecida de; Martins, Adalvan Daniel; Pio, Leila Aparecida Salles; Pasqual, Moacir.
 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...

Natural efficiency of parasitism by Billaea rhynchophorae (Blanchard) (Diptera: Tachinidae) for the control of Rhynchophorus palmarum (L.) (Coleoptera: Curculionidae) Neotropical Entomology
Moura,José Inacio L.; Toma,Ronaldo; Sgrillo,Ricardo B.; Delabie,Jacques H.C..
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.

Primeira ocorrência de Alcaeorrhynchus grandis (Dallas) (Hemiptera: Pentatomidae) predando lagartas desfolhadoras do dendezeiro no estado do Pará Neotropical Entomology
Ribeiro,Rafael C; Lemos,Walkymário P; Bernardino,Aline S; Buecke,Joel; Müller,Antonio A.
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.
