A silvicultura urbana compreende todas as atividades relacionadas a implantação e manejo da vegetação presente nas cidades, podendo ocorrer nos espaços verdes públicos ou privados e proporciona diversos benefícios socioambientais. O objetivo do trabalho foi identificar a ocorrência de espécies frutíferas utilizadas na alimentação de seres humanos e avifauna em 4 bairros e 11 praças do município de Santarém, Pará, através do inventário total destas áreas, considerando somente os indivíduos com altura igual ou superior a 1,5m. Foram calculadas a Frequência absoluta (FR) e Frequência relativa (FR) de cada espécie alimentar em relação ao número total de indivíduos inventariados. Quanto à origem das espécies, foram classificadas como exóticas ou nativas. Além disso, utilizando o método de revisão de literatura, foram apontadas características acerca do tamanho e peso dos frutos.  Foram contabilizados 1646 indivíduos arbóreos, distribuídos em 63 espécies de 31 famílias botânicas. Sendo classificadas como frutíferas de capacidade alimentícia para humanos e/ou avifauna 660 indivíduos, de 22 espécies pertencentes a 10 famílias, com destaque para a Mangueira (Mangifera indica L.), Oitizeiro (Licania tomentosa), Jambeiro (Syzygium malaccense), Castanhola (Terminalia catappa), Cajueiro (Anacardium occidentale) e  Goiabeira (Psidium guajava) com maior número de representantes. Desta forma, é possível afirmar que a arborização no município de Santarém é composta por 40,09% de espécies frutíferas alimentares à população e avifauna local.

Keberadaan ruang terbuka hijau (RTH) di Kelurahan Komet sangat diperlukan keberadaannya. Jumlah, jenis dan distribusi vegetasi yang sudah ada perlu diketahui untuk membuat perencanaan RTH taman kota dan taman lingkungan yang dibutuhkan di Kota Banjarbaru. Oleh sebab itu, selain untuk menginventarisir RTH taman kota dan taman lingkungan yang ada, juga perlu dilakukan analisis variasi kemampuan serapan CO2 atmosfir beberapa jenis pohon penyusun ruang terbuka hijau Kota Banjarbaru, khususnya Kelurahan Komet. Tata hijau yang digunakan dalam lansekap kawasan taman menggunakan pohon yang bertajuk lebar dan didominansi pohon seperti akasia (Acacia mangium), jambu air (Eugenia aquea), mangga (Mangifera indica), sawo (Manilkara zapota), rambutan (Nephelium lappaceum), jambu biji (Psidium guajava), angsana (Pterocarpus indicus), mahoni berdaun lebar (Swietenia macrophylla), dan ketapang (Terminalia catappa). Penyerapan tertinggi tercatat pada pohon angsana (Pterocarpus indicus) yaitu sebesar 720 kg.tahun-1, sedangkan yang terendah pada pohon jambu biji (Psidium guajava), dan mahoni berdaun lebar (Swietenia macrophylla) yaitu sebesar 61 kg.tahun-1. Kata Kunci: Banjarbaru, serapan CO2, taman. The existence of green open space in Comet Village is indispensable. The number, type and distribution of existing vegetation should be known to make urban park planning and environmental parks needed in Banjarbaru City. Therefore, in addition to the inventory green open space park city and environmental parks that exist, it is also necessary to analyze the variation of atmospheric CO2 absorption capacity of several types of trees making up green open space Banjarbaru City, especially Comet Village. The green streets used in the landscape of the park area use wide-brim and tree-dominated such as Acacia mangium, Eugenia aquea, Mangifera indica, Manilkara zapota, Nephelium lappaceum, Psidium guajava, Pterocarpus indicus, Swietenia macrophylla and Terminalia catappa. The highest absorption was recorded in Pterocarpus indicus tree which was 720 kg.year-1, while the lowest in Psidium guajava and Swietenia macrophylla tree was 61 kg.year-1.Keyword : Banjarbaru, CO2 absorption, park.

The oral cavity provides an ideal environment for the growth of microbiota. Many of the bacterial species in the oral cavity are involved in dental caries. Acidogenic and aciduric Gram positive bacteria, metabolize sucrose to organic acid, which dissolves the calcium phosphate in the teeth resulting in decalcication and nally causing decay. Therapeutic drugs used to treat dental diseases may have many undesirable effects such as diarrhea, vomiting and tooth staining. Therefore, natural phytochemicals isolated from plants used in traditional medicines are considered as a good alternative to synthetic chemicals. Therapeutic and chemical methods are costly but there are many easily available plants which we can use for cleaning our teeth and maintaining our oral hygiene. A study was undertaken to investigate the antimicrobial effect of , , Psidium guajava Mangifera indica Anacardium occidentale Azadirachta indica and on oral normal microora. Ethanolic and aqueous extracts of the leaves were prepared and was tested against the three isolates from the oral cavity using Agar well diffusion method namely Gram positive αhaemolytic cocci in chain, Gram positive non-haemolytic cocci in chain and Gram positive bacilli. and Psidium guajava Anacardium occidentale was found to be effective against the isolates. From this study and have shown Psidium guajava Anacardium occidentale great potential to act as natural and cost effective alternative for maintaining oral hygiene.

AbstractThis study was undertaken to examine changes in the content of pigments and accumulation of metals from vehicular pollution in selected species of roadside trees under vehicular pollution. A major arterial road with heavy vehicle emissions in the Kumasi Metropolis was designated as the polluted site, while Kwame Nkrumah University of Science and Technology Campus was designated as the control site. Four tree species (Terminalia catappa, Mangifera indica, Ficus platyphylla and Polyalthia longifolia) selected for the study were well distributed and abundant in the polluted and control sites. Photosynthetic pigments and levels of heavy metals (Pb, Cu, Cd and zinc) were assessed in their leaves. Chlorophyll and carotenoid contents were determined by absorption spectrometry, while the metal accumulation index (MAI) was used to determine the total metal accumulation capacity of the tree species. We observed a reduction in photosynthetic pigments in the leaf samples from the polluted site. Ficus platyphylla had the maximum reduction in total chlorophyll (49.34%), whereas Terminalia catappa recorded the lowest reduction (33.88%). Similarly, the largest decrease (31.58%) of carotenoid content was found in Terminalia catappa trees and the lowest in Polyalthia longifolia (16.67%). The Polyalthia longifolia, Ficus platyphylla and Terminalia catappa leaf samples collected at the polluted site recorded a higher ratio of chlorophyll a/b. Heavy metal (Cu, Pb, Zn and Cd) accumulation in leaf samples was higher in the polluted site than in the control, as expected. The highest metal MAI value was recorded in Mangifera indica (5.35) followed by Polyalthia longifolia with 4.30. The findings from this study specifically demonstrate that air contamination induced by vehicles decreases the level of photosynthetic pigments in trees subjected to roadside emissions. It is clear that both chlorophyll a/b and chlorophyll/carotenoid ratios will act as very useful stress-level markers. Elevated heavy metal levels in the tree species along arterial roadsides indicate that they serve as heavy metals sink. The change in MAI resulting from different pollution burden is an indication that the removal capabilities of the tree species differ from each other. We therefore suggest M. indica and P. longifolia as potential species to be used in air pollution reduction plans in the city.

Foi realizado um levantamento das intoxicações por plantas em 20 municípios do Sertão Paraibano, onde foram entrevistados 50 produtores e 11 médicos veterinários. De acordo com o levantamento realizado, Ipomoea asarifolia e Mascagnia rigida são as intoxicações mais importantes. Indigofera suffruticosa, as plantas cianogênicas (Sorghum vulgare, Piptadenia macrocarpa e Manihot spp.), Mimosa tenuiflora, Aspidosperma pyrifolium e Crotalaria retusa são plantas importantes como causa de intoxicações na região. Os entrevistados relataram casos esporádicos de intoxicação por Ricinus communis, Enterolobium contortisiliquum, Prosopis juliflorae Brachiaria decumbens. Ziziphus joazeiro, Passiflora sp., Caesalpina ferrea e Crescentia cujete foram mencionadas como causa de abortos em ruminantes. Frutos de Crescentia cujete foram administrados a duas cabras prenhes causando mortalidade perinatal e abortos. As cascas de feijão (Phaseolus vulgaris e Vigna unguiculata) e as folhas de Licania rigida (oiticica) são associadas à sobrecarga ruminal em bovinos. As frutas de Mangifera indica (manga)e Anacardium occidentale (cajú) são responsabilizadas por causarem intoxicação etílica. Dalechampia sp. e Croton sp. foram citadas pelos entrevistados como possíveis plantas tóxicas, que ainda não tiveram sua toxicidade comprovada.
