“…The richness and diversity of bee visitors of E. uniflora was much higher than the 11 species recorded by Silva and Pinheiro (2007) in the western part of the municipality of Rio de Janeiro (Rio de Janeiro state, Brazil).High values of richness and diversity indicate, in most cases, a well-structured community, with many rare species (Costa et al, 1993). According to Michener (1979), southern Brazil it is one of the regions in the world with the highest richness of Apoidea.…”

Eugenia uniflora L. (Myrtaceae) is pollinated mostly by bees and there are no restrictions for pollen collection in their flowers. This stimulated us to study the bee diversity on its flowers in two forest fragments in southern Brazil, in August and September, 2012. A total of 826 bees belonging to 39 species and four subfamilies were captured with entomological nets. Halictinae presented the greatest richness, followed by Apinae, Colletinae and Andreninae. Apis mellifera was the only common species and the most abundant, followed by Scaptotrigona bipunctata and Melipona obscurior. Seven species were classified as intermediate and 31 as rare. Highest numbers of bees were collected from 10 to 11:30 h. The species richness of flower visiting bees was much higher than that of previous studies with first records of Plebeia remota and Anthrenoides paolae. Eugenia uniflora is a food source for exotic and native bees and possibly contributes to the conservation of these bees in forest fragments. In return, the bees probably act in maintaining this plant native of the Atlantic Forest.

“…On the other hand, M. scabrella presents a very complex interaction with cochineal insects that are transported by ants up to the trunks and branches. These insects, after sucking the sap, excrete a transparent and sweet liquid that attracts a great diversity of insects (flies, bees, butterflies) and birds (hummingbirds and insectivores), as reported by Costa et al (1993). Some perisporiaceous fungi grow saprophytically on leaves, branches and trunk, depending also on that sugary substance (FIDALGO; FIDALGO, 1967).…”

A Pilot Reclamation Project (PRP) was developed in 1982 by the Environmental Protection Agency of the State of Santa Catarina-Brazil, with the objective to evaluating the adaptation of woody species to a land degraded by coal mining. After a full topographic reconstitution of the landscape, addition of nutrient load and sowing of herbaceous species, the area was split into 12 plots in which seedlings of 12 tree species were planted: three native trees [Bastardiopsis densiflora (Hook. & Arn.) Hassl., Mimosa scabrella Benth., Schizolobium parahyba (Vell.) Blake] and nine exotic species [Eucalyptus saligna Sm., E. viminalis Labill., E. citriodora Hook., Grevillea hilliana F.Muell., Hovenia dulcis Thunb, Melia azedarach L., Pinus elliottii Engelm., P. taeda L., Syzygium cumini (L.) Skeels]. After 22 years, from the beginning of the PRP, the exotic species presented higher percentage of survival than native species; the plots which received either B. densiflora and S. parahyba or were covered only with herbaceous vegetation associated with solely a few shrubs. Conversely, the plots which received seedlings of M. scabrella displayed clear evidence of restoration in progress. The study conducted in plots that have received M. scabrella indicate an improvement of nutrient load (N, K, organic matter) in the substrate, a diversified composition of tree coverage (very similar to the nearby remnants of the Atlantic Rainforest) and other life forms, with prominent establishment of native trees with predominance of zoophilous and zoochorous species. Some characteristics of M. scabrella that could explain its outstanding capacity to enhance the restoration of the Atlantic Rainforest are also discussed along this paper. Mimosa scabrella BENTH.

Após uma completa reconstituição topográfica da paisagem, além da carga de nutrientes e sementes de espécies herbáceas, a área foi dividida em 12 pontos onde foram plantadas mudas de 12 espécies de árvores: três espécies nativas [Bastardiopsis densiflora (Hook. & Arn.)

Skeels]. Após 22 anos, as espécies exóticas apresentaram elevada taxa de sobrevivência em comparação com as espécies nativas; os pontos que receberem B. densiflora e S. parahyba foram cobertos apenas com espécies herbáceas associadas com alguns arbustos. Reciprocamente, os pontos que receberam mudas de M. scabrella demonstraram claras evidências no processo de restauração. O estudo conduzido em pontos que ...

Caldasia 38 (1):197-210. 2016 RESUMEN El dosel arbóreo constituye un complejo hábitat con gran diversidad de insectos. Los estudios sobre insectos del dosel están mayormente concentrados en bosques húmedos tropicales y son escasos en bosques secos subtropicales. El propósito de este trabajo fue caracterizar la entomofauna del dosel de bosques secos subtropicales, analizando su diversidad regional y localmente. Para ello se muestrearon cinco sitios localizados en la región fitogeográfica del Chaco Semiárido Argentino. Las recolecciones de insectos se realizaron durante el período estival y mediante la técnica de vareo de ramas (beating). Se recolectaron 963 insectos pertenecientes a nueve órdenes y 79 familias. La composición taxonómica y la distribución de la abundancia de familias fueron diferentes en los sitios estudiados. Las condiciones ambientales propias y los disturbios antrópicos de los sitios influyeron en la determinación de los agrupamientos taxonómicos y en la distribución de la abundancia de los insectos. Los resultados que se presentan en este trabajo constituyen los primeros datos sobre la diversidad de insectos del dosel en bosques secos subtropicales, y aportan conocimientos iniciales para futuros estudios sobre interacciones ecológicas y, en general, sobre la diversidad del dosel de estos bosques.Palabras clave. Ensambles de insectos, abundancia, diversidad, Chaco Semiárido, Argentina. ABSTRACTThe canopy is a complex habitat with a great diversity of insects. Most studies on canopy insects refer to tropical rain forests, and seldom to subtropical dry forests. The purpose of this study is to characterize the insect fauna in the canopy of subtropical dry forests, analyzing their diversity both regional and local. Samples were taken in five sites located in the phytogeographical district known as Semiarid Chaco, in Argentina. A total of 963 insects, belonging to 9 orders and 79 families, were collected in the summer by using the "branch-beating" technique. Differences in family abundance distribution and in taxonomic composition were among between sites, resulting in low similarity values. Environmental conditions and human disturbance in the sites might have influenced the taxonomic composition and the distribution of insect abundance. This paper provides the first data on the diversity of canopy insects in subtropical
