1. Prediction of diametric and dynamic structures in a semiarid forest (Caatinga) area submitted to Forest Management, Brazil
ABSTRACT Dynamics studies associated with prognosis can support planning actions for the conservation and sustainable use of forest resources. Therefore, the objective of this study was to evaluate the dynamics and predict the diameter structure using the Markov chain model for an area of caatinga forest submitted to different management practices. The study

2. Diametric distribution modeling of forest species in arboreal Caatinga vegetation, Brazil
ABSTRACT The distribution modeling in diameter classes is an important indicator of the potential use of a forest community, as well as the projection of future forest production. The objective of this study was to evaluate the diametric structure and to select probabilistic density functions for three woody species in forested arboreal Caatinga vegetation i

3. Influence of shadowing in Sequoia sempervirens (D. Don) Endl. mini-stumps and mini-cuttings
ABSTRACT The aim of the work was to analyze the influence of variables such as shading, temperature and humidity in the production and rooting of mini-cuttings of Sequoia sempervirens (D. Dom) Endl. in a clonal mini-garden. The experiment was conducted at the Forest Nursery at the University of Santa Catarina State - CAV/UDESC, Lages - SC. The minicuttings w

4. Population structure, diametric distribution and use of Commiphora leptopholoeos (Mart.) JB Gillett in arboreal Caatinga
ABSTRACT The objective of this work was to characterize the population structure, analyze the spatial distribution pattern and identify the potential use of the Commiphora leptopholoeos in the Contendas do Sincorá National Forest, BA. Thus, three disjoint transects of 40 x 160 m were installed for the phytosociological study and spatial distribution and sub

5. EVALUATION OF DIVERSITY AND GENETIC STRUCTURE AS STRATEGIES FOR CONSERVATION OF NATURAL POPULATIONS OF Dalbergia nigra (Vell.) Allemão ex Benth.
ABSTRACT: The evaluation of diversity and genetic structure allows us to verify with precision the effect of evolutionary and anthropic processes on species. The objective of this research was to evaluate the divergence and the genetic structure of two natural populations of Dalbergia nigra, using molecular markers Inter Simple Sequence Repeats (ISSR). Leaf

6. Monitoring and risk assessment due to presence of metals and pesticides residues in honey samples from the major honey producing forest belts and different brands
Abstract Honey is consumed worldwide because of its nutritional, therapeutic and medicinal purposes. Generally it is perceived that honey reaches its consumer in pure form however this is not always true as contaminants can end up in honey. Thus this study was designed to check the presence of contaminants in honey samples. For this purpose 52 samples were c

7. Lugares: relações entre corpo e linguagem
ABSTRACT In Santa Catarina State, forest classification in successional stages is supported by the National Council of the Environment (CONAMA) Resolution. However, this classification presents several inconsistencies. This study aimed to evaluate the classification accuracy of three classifications schemes of successional stages proposed for the Subtropical

8. SUCCESSIONAL STAGES OF SANTA CATARINA ATLANTIC SUBTROPICAL EVERGREEN RAINFOREST: A CLASSIFICATION METHOD PROPOSAL
ABSTRACT In Santa Catarina State, forest classification in successional stages is supported by the National Council of the Environment (CONAMA) Resolution. However, this classification presents several inconsistencies. This study aimed to evaluate the classification accuracy of three classifications schemes of successional stages proposed for the Subtropical

10. Helechos y Licofitas de la Reserva de Biosfera Yabotí, Misiones, Argentina: Parque Provincial Moconá
Abstract Abstract The Parque Provincial Moconá is in the east of the Misiones province, surrounded by Yabotí and Uruguay rivers. It belongs to Yabotí Biosphere Reserve, and together with other Biosphere’s protected areas, it represents one of the main relicts of the Paranaense forest in the country. In this work, fern and lycophyte species that grow in

11. Decline in Giant Tree Numbers: Status Report for Santa Catarina State and Perspectives for Brazil
ABSTRACT Loss of large trees due to indiscriminate timber cutting and opening of new areas for human use is a global problem. Brazil is well known for tree species richness within its extensive forested areas composed of various biomes. Giant trees are “key” to recognize the original forest structure. Decline of their populations in Brazil may be estimat
