Combustion performance of charcoal: a comparative study on Miombo woodland native species and Eucalyptus grandis

Species of Scolytidae and Platypodidae were evaluated in a plantation using a clone of Eucalyptus grandis x Eucalyptus urophylla in the State of Minas Gerais, Brazil. Wood disks with galleries were taken from 15 eucalyptus trees between 0.5 and 1.5 m height. After collection, all trees attacked were burned. Woodborers obtained from these disks were identified as Premnobius cavipennis, Premnobius ambitiosus, Dryocoetoides cristatus (Coleoptera: Scolytidae) and Euplatypus parallelus (Coleoptera: Platypodidae). This is the first report of D. cristatus, a Brazilian native species, damaging eucalyptus, which shows its adaptation to this plant.

O objetivo deste trabalho foi caracterizar as espécies arbóreas introduzidas no paisagismo de cinco parques urbanos de Curitiba, principalmente no aspecto relativo às espécies exóticas invasoras. Sortearam-se aleatoriamente cinco parques: Passeio Público, Parque Bacacheri, Parque São Lourenço, Parque Barigui e Parque Municipal do Passaúna. As árvores foram identificadas quanto a taxonomia e origem. Foram analisados 5525 indivíduos arbóreos, sendo identificados 95,9% até o nível de espécie. Da população analisada, foram identificadas 149 espécies e 48 famílias. Apenas 7 famílias representam 50% do total, com predominância de Fabaceae (20,8%), sendo que o maior número de famílias verificou-se no Parque São Lourenço. Quanto à origem, 38,25% são nativas de Curitiba, 24,83% são espécies nativas do Brasil e 24,83% são espécies exóticas. Encontraram-se 13 espécies exóticas invasoras: Citrus limon, Eriobotrya japonica, Eucalyptus grandis, Eucalyptus robusta, Eucalyptus viminalis, Eucalyptus sp., Hovenia dulcis, Ligustrum lucidum, Melia azedarach, Morus nigra, Pinus elliottii, Pinus sp. e Pittosporum undulatum. Psidium guajava foi a única espécie nativa do Brasil considerada invasora no Paraná. O Passeio Público foi o parque com maior número de espécies exóticas invasoras, enquanto o Parque Municipal do Passaúna apresentou maior número de espécies nativas de Curitiba.Palavras-chave: Áreas verdes; espécies exóticas; espécies nativas.AbstractInvasive tree species in urban parks landscaping of Curitiba, PR. The aim of this study was to characterize the introduced tree species in landscaping of five urban parks of Curitiba, mainly concerning invasive species. Five parks were randomly selected: “Passeio Público”, “Parque Bacacheri”, “Parque São Lourenço”, “Parque Barigui” and “Parque Municipal do Passaúna”. The trees were identified according to the taxonomy and origin. 5525 trees were analyzed, 95.9% were identified at species level. From the analyzed population, 149 species were identified as well as 48 families. Only 7 families represent 50% of all families, with a predominance of Fabaceae (20.8%), and the largest number of families was found in “Parque São Lourenço”. In relation to the origin, 38.25% of trees are native of Curitiba, 24.83% are native of Brazil and 24.83% are exotic species. 13 invasive alien species had been found: Citrus limon, Eriobotrya japonica, Eucalyptus grandis, Eucalyptus robusta, Eucalyptus viminalis, Eucalyptus sp. Hovenia dulcis, Ligustrum lucidum, Melia azedarach, Morus nigra, Pinus elliottii, Pinus sp and Pittosporum undulatum. Psidium guajava was the only Brazil native species considered invasive in Paraná. The “Passeio Público” is the park with the highest number of invasive alien species, and the “Parque Municipal Passaúna” had the greatest number of native species of Curitiba.Keywords: Green areas; alien species; indigenous species.

Shape Influence

The relationship between leaf breakdown and colonisation by invertebrates in tropical aquatic ecosystems is poorly understood, especially in regard to the added problem of the potential effects of exotic species. To assess the colonisation by invertebrates during leaf breakdown in a third-order headwater stream in south-eastern Brazil, we conducted an experiment using the native species Miconia chartacea, the exotic species Eucalyptus grandis and artificial leaves. We hypothesised that the quality of the detritus and the leaf shape influence invertebrate colonisation because of the quality of the food and refuge offered by leaf detritus. Invertebrate density and richness were higher on leaves of E. grandis than on those of M. chartacea. Taxon richness did not differ among M. chartacea and the two sizes of artificial leaves offered, probably as a function of the chemical composition of E. grandis. Total invertebrate density was significantly higher in the organic detritus, suggesting that detritus provides food for the organisms. Our results indicate that the colonisation of invertebrates is probably affected by the chemical composition of detritus. Contrary to expectations, the community of invertebrates had no difficulty in colonising E. grandis, although it is an exotic species. In addition, the shredder activity did not influence leaf breakdown. These results may indicate that the invertebrates in this stream tend to behave as generalist feeders.

The Caribbean

In this paper an updated list of the 43 Caribbean taxa of Agave, plus nine taxa only know as cultivated plants is given. A comparative study of the main species is done using their most important morphological characters; this allows to separate 12 native species that are different and representative, in such a way that is possible to join the rest of the related species. Aspects of the relationships among the Caribbean species and their continental relatives are discussed. illustrative drawings, tables and a map with the distribution of the taxa are also given.
