1. Tamaulipan thornscrub after fire: an analysis of the composition of species
Resumo Os incêndios florestais são um elemento natural em muitos ecossistemas terrestres, no México uma das principais causas de perda de cobertura vegetal está relacionada a eles, no entanto, nenhuma pesquisa foi realizada nas comunidades de espinheiros de Tamaulipan sobre as estratégias regenerativas pós-fogo de espécies de plantas, portanto, é imp

2. Aspectos ecológicos das espécies regenerantes de uma floresta urbana com 150 anos de sucessão florestal: o risco das espécies exóticas
Resumo A presença de florestas dentro de centros urbanos tem grande importância, principalmente devido aos serviços ecossistêmicos proporcionados por elas. Fragmentos urbanos são pouco estudados e trabalhos quantitativos focados na flora arbórea na área do presente estudo nunca foram realizados. O objetivo foi avaliar a composição, estrutura e diver

3. Influence of Fire on the Natural Regeneration of a Semideciduous Seasonal Rainforest Fragment
ABSTRACT The objective was to evaluate the influence of fire in a forest fragment through litter biomass analysis, regeneration of Cecropia sp., and canopy openness. Two treatments were established, one of them corresponding to an area affected by fire (T1) and the other not affected by fire (T2), both areas encompassing 0.3 ha of forest. Samples were colle

4. Community Succession in an Urban Novel Forest after Four Decades of Regeneration
ABSTRACT This study aimed to analyse the tree community of an urban forest with 40 years of natural regeneration after abandonment of the degraded land. We hypothesized that after four decades of forest succession, the diversity, structure and functional aspects of the community would be similar to other secondary surrounding forests. We established ten plo

5. In vitro Callus Induction and Plant Regeneration of Celosia argentea- An Important Medicinal Plant
Celosia argentea (Var.) cristata (Amaranthaceae) is a widely cultivated ornamental plant, which has antibacterial, astringent, haemostatic, hypertensive, ophthalmic, and parasitic significance. This study describes a protocol for in vitro callus induction and plant regeneration from leaf and stem explants of C. argentea using Murashige and Skoog (MS) medium.

6. Micro-sítio como filtro para o estabelecimento de regenerantes arbóreos em áreas restauradas / Microsites as filters for tree species establishment under restoration plantings
The characteristics of the natural regeneration of restoration plantings understory express the main indicators of success of ecological restoration projects, in which the absence of regeneration indicates a bottleneck for the perpetuation of forest communities inserted into highly fragmented landscapes. Nevertheless, adverse conditions of the micro-site of

7. Dinâmica populacional e efeitos de variáveis ambientais sobre a fauna de pequenos mamíferos em um fragmento de floresta com araucária no sul do Brasil
Natural populations of small rodents fluctuate continually over time and the population dynamics of any living organism are shaped by both intrinsic and extrinsic factors. Small mammals populations can show a continuum dynamic activity, ranging from stability to regular cycles of variable amplitude. The species dynamics is also known to be influenced by the

8. MECHANISMS OF NATURAL REGENERATION IN ESTACIONAL DECIDUAL FOREST, SANTA MARIA, RS / MECANISMOS DE REGENERAÇÃO NATURAL EM FLORESTA ESTACIONAL DECIDUAL, SANTA MARIA, RS
This study evaluated the mechanisms of natural regeneration represented by seeds rain, seeds bank of the soil and the regeneration vegetation, considering the seedlings bank and the established regeneration, in a fragment of Estacional Decidual Forest. The evaluation was made with 70 randomized samplings in 14 parcels inside four bands, with systematic distr

9. Floristic composition and structure of the shrub-arboreal component of the Parque Natural Municipal da Cratera de Colônia, São Paulo, SP. / Composição florística e estrutura do componente arbustivo-arbóreo do Parque Natural Municipal da Cratera de Colônia, São Paulo, SP
The conservation of the biodiversity has been theme debated in several environment meeting in the world. The forestal areas near urban centers have received little attention from conservative programs, because many people belief that these areas are irreparably degraded. However, if adequately investigated, these areas could be useful indicating the patterns

10. Characterization of the shrub and tree vegetation from Montane Ombrophilous Dense Forest fragments / Caracterização da vegetação arbustivo-arborea de fragmentos de Floresta Ombrofila Densa Montana
The Atlantic Forest possesses enormous biodiversity and is highlighted by the high floristic diversity and endemism in some plant groups. The Atlantic Forest is among the most endangered tropical forests in the world and most of its remnants are small and altered fragments, or larger areas in mountains, with pronounced slope. Knowledge of the forest remnants

11. EFECTO DEL RELIEVE Y LA INTENSIDAD DE TRÁNSITO EN COSECHA SOBRE LA DINÁMICA DE LA REGENERACIÓN NATURAL DE UN BOSQUE NEOTROPICAL EN MISIONES, ARGENTINA
ABSTRACT An experiment was carried out to evaluate the dynamics of the natural regeneration settled down in the skid trails and the influence of the slope and the traffic intensity on them, comparing three and five years after logging. The forest belongs to Selva Paranaense, type of forest in the Yabotí Biosphere Reserve, and in the Guarani Reserve of the M

12. Regime de distúrbio e dinâmica da regeneração natural na Floresta Pluvial Atlântica Submontana / Disturbance regime and natural regeneration dynamics in the Lower Montane Atlantic Rain Forest
In a 10.24 ha permanent plot of Tropical Lower Montane Atlantic Rain Forest in the Carlos Botelho State Park (Sete Barras, SP, Brazil), this study aimed to describe the canopy disturbance regime and to assess natural regeneration under different light regimes. In order to do so, the plot was completely surveyed for canopy gaps that were measured and had thei
