1. Trade-off in plant-ant interactions: seasonal variations
Resumo Este trabalho avaliou o efeito da sazonalidade sobre a interação planta-formiga em uma Floresta Tropical Sazonal Seca, utilizando como modelo ecológico a espécie Ipomoea carnea subs. fistulosa (Convolvulaceae). Realizamos coleta sistemática de formigas, herbívoros e folhas em plantas marcadas, avaliamos a eficiência de captura de herbívoros pe

2. Spatial-temporal variation in litterfall in seasonally dry tropical forests in Northeastern Brazil
Resumo A produção de serapilheira é essencial para a ciclagem de nutrientes em ecossistemas terrestres. De Novembro de 2009 a Outubro de 2011, foi analisada a produção de serapilheira em duas áreas de Caatinga, um tipo de Floresta Tropical sazonalmente Seca localizada no Cariri Paraibano, na região do semiárido da Paraíba, Nordeste do Brasil. Uma da

3. Muscidae (Diptera) of medico-legal importance associated with ephemeral organic substrates in seasonally dry tropical forests
Abstract Muscidae (Diptera) comprises one of the most important taxa in medical, veterinary and forensic entomology, especially due to their association with decomposing carcasses and cadavers. Yet, knowledge on their distribution and behaviour is still incipient in several biomes, which is the case of dry tropical forests. This study aimed to evaluate the a

4. Post-fire regeneration in seasonally dry tropical forest fragments in southeastern Brazil
ABSTRACT Seasonally dry tropical forest is one of the highly threatened biome. However, studies on the effect of fire on these tree communities are still scarce. In this context, a floristic and structural survey in three forest areas in the southeast of Brazil that were affected by fire between 14 and 25 years ago was performed with the objective of evaluat

5. Do seedling functional groups reflect ecological strategies of woody plant species in Caatinga?
ABSTRACT It is assumed that morphological traits of seedlings reflect different strategies in response to environmental conditions. The ecological significance of this has been widely documented in rainforests, where habitat structure and species interactions play an important role in community assembly. However, in seasonally dry ecosystems, where environme

6. Effect of water stress on seedling growth in two species with different abundances: the importance of Stress Resistance Syndrome in seasonally dry tropical forest
ABSTRACTIn seasonally dry tropical forests, species carrying attributes of Stress Resistance Syndrome (SRS) may have ecological advantages over species demanding high quantities of resources. In such forests, Poincianella bracteosa is abundant, while Libidibia ferrea has low abundance; therefore, we hypothesized that P. bracteosa has characteristics of low-r

7. Biogeografia e estrutura da comunidade de lagartos dos enclaves de floresta estacional decidual de São Domingos - GO (Vale do Paranã)
A composição e os padrões biogeográficos de formação da comunidade de lagartos dos enclaves de Florestas Estacionais Deciduais (FEDs) na região do Cerrado (São Domingos-GO) foram estudados com objetivo de determinar se as distribuições das espécies são associadas com a Região das Florestas Tropicais Sazonais, nova unidade fitogeográfica previam

8. A importância das palmeiras arborescentes de grande porte na dinâmica das florestas amazônicas sazonalmente secas.
We investigated and compared the determinants of palm diversity at different spatial scales: along a moisture gradient in a seasonally dry Amazonian forest and using a climatic model comprising the entire Brazilian territory. Climatic hazards seem to strongly determine the distribution of palms, with the relative importance of moisture being highly consisten

9. Sistematica de Acosmium s.l. (Leguminosae, Papilionoideae, Sophoreae) e estudos de morfologia de plantulas e numeros cromossomicos
Acosmium Schott (Leguminosae, Papilionoideae, Sophoreae) is a neotropical genus comprising 18 species. In the last revision of the genus four sections were recognized by Yakovlev, distinguished by the ratio between the length ofthe calyx teeth with the length of the calyx tube, curvature of radic1e and stamens number. The general aim of this thesis was to ev
