13. Forecasting the impact of an invasive macrophyte species in the littoral zone through aquatic insect species composition
ABSTRACT Invasive macrophytes threaten freshwater ecosystem biodiversity. We analyzed the impact of the invasive white ginger lily (Hedychium coronarium J. König, Zingiberaceae) on aquatic insect assemblages living in the littoral zone of a tropical reservoir. We took aquatic insect samples in the littoral zone on four main vegetal profile banks: white ging

14. Land Use and Environmental Zoning of Mixed Ombrophilous Forests for Sustainable Use (Irati National Forest, Brazil Southern Region)
ABSTRACT An environmental zoning proposal due to the demand to develop strategies to ensure biodiversity scenarios for the remaining mixed ombrophilous forests was carried out for the Irati National Forest, a legally protected area for sustainable use located in southern Brazil. To identify land use and cover, Ikonos PSM images dated from December 2004, base

15. Distribution patterns of ferns and lycophytes in the Coastal Region of the state of Rio Grande do Sul, Brazil
ABSTRACT A survey of ferns and lycophytes of the Coastal Region of the state of Rio Grande do Sul (CRRS) was performed based on field work and collections of the main regional herbaria. The following were evaluated for each species: preferential habits (terrestrial, epiphytic or aquatic), geographic distribution patterns and habitats (forest, grassland, and

17. Species composition, diversity, and vegetation structure in a gallery forest-cerrado sensu stricto transition zone in eastern Mato Grosso, Brazil
ABSTRACTWe investigated the existence of an ecotone in the species composition, diversity and vegetation structure in the transition between gallery forest and cerrado sensu strictoin central Brazil. We tested two hypotheses: 1) a ecotone can be found between gallery forest and cerrado; 2) a gradient exists in the species composition of the cerrado. We estab

18. Post-fire dynamics of the woody vegetation of a savanna forest (Cerradão) in the Cerrado-Amazon transition zone
ABSTRACTFire can change the species composition, diversity, and structure of savanna vegetation, thus altering growth and mortality rates. Such changes in the woody vegetation of burned savanna forest were evaluated over four years in comparison to unburned savanna forest. All woody plants with a diameter at breast height > 10 cm were measured in 100 permane

19. MODELOS PREDICTIVOS DE BIOMASA AÉREA DE Eucalyptus grandis PARA EL NORESTE DE ARGENTINA
ABSTRACT Different industrial, environmental and energy interests have led, in recent years, to the analysis of different possibilities for utilization of forest biomass is gaining an increasing role, so that quantification of the biomass from these forest systems is an essential first and an unavoidable step. The aim of this study was to develop models whic

20. Orchidaceae in an Atlantic Forest area: floristics and similarity to other Dense Ombrophilous Forest fragments
The Brazilian Atlantic Forest is considered a global hotspot for biodiversity although it is currently threatened and highly fragmented. Orchidaceae in this phytogeographical domain is represented by 148 genera, of which 142 are endemic; Rio de Janeiro State contains approximately one third of all Brazilian orchid species. The Wildlife Protection Zone of the

21. DOS ESPECIES NUEVAS (OLIGOCHAETA: TUMAKIDAE) DE LA REGIÓN CARIBE DE COLOMBIA
ABSTRACT Two new species of earthworms (Oligochaeta: Annelida) Tumakidae family; Tumak amari sp. nov. and Tumak congorum sp. nov. are described and illustrated. They were collected in relict forest fragments adjacent to wetlands in the southerm region of Cesar department of Cesar, in the Colombian Caribbean. Tumakidae family is characterized mainly by of the

22. Isolation and molecular characterization of Rhizoctonia-like fungi associated with orchid roots in the Quadrilátero Ferrífero and Zona da Mata regions of the state of Minas Gerais, Brazil
Mycorrhizal associations can be considered required for orchids, which depend on the fungi for germination and establishment in natural conditions. Knowledge of the mycorrhizal fungi is important for programs aimed at the reintroduction, conservation and management of orchid species. The objective of this study was the molecular characterization of Rhizocton

23. Patrones de diversidad y composición florística de parcelas de evaluación permanente en la selva central de Perú
A forest survey in Satipo Province, Region of Junin, from 990 to 1050 m.a.s.l. revealed the presence of 775 trees > 10 cm dbh belonging to 102 species, 67 genera and 37 families. The study showed the most diverse families as being Moraceae, Lauraceae and Leguminosae, and the most diverse genera as Ficus, Ocotea, Miconia and Inga. A comparative analysis of 1
