1. Risk of genetic vulnerability and aspects of the reproductive biology of Psychotria ipecacuanha (Rubiaceae), a threatened medicinal plant species of Brazilian forests
ABSTRACT Psychotria ipecacuanha, commonly known as Ipeca, is a medicinal plant of pharmacological and economic value. The species is distylous; it has populations with two floral morphs, one with long and one with short styles. Apart from the presence of two floral morphs in a balanced ratio (1:1), reciprocal herkogamy of the reproductive organs between alte

2. ENDOPHYTIC FUNGI FROM THE BRAZILIAN FLORA AND THEIR EMPLOYMENT IN BIOTRANSFORMATION REACTIONS
The biotransformation reactions are used as a successful alternative to derivatization by the traditional chemistry because they conduct to uncommon reactions, which would hardly be carried out by chemical synthesis. A wide diversity of compounds may be metabolized by fungi, leading to chemical derivatives through selective reactions that work under ecofrien

3. Relating flight initiation distance in birds to tropical dry forest restoration
ABSTRACT Flight initiation distance (FID), defined as the distance at which an individual flees from an approaching predator, might depend on how the individual perceives the risk of being predated. Using a standardized walking approach method on focal bird individuals, we investigated whether different levels of vegetation cover (habitat) influence the perc

4. Species of Drosophila (Diptera: Drosophilidae) attracted to dung and carrion baited pitfall traps in the Uruguayan Eastern Serranías
This study investigates the species richness and abundance of Drosophila Fallén, 1823 attracted to dung and carrion baited pitfall traps in natural areas with heterogeneous habitats at the Sierra de Minas, Eastern Serranías, southeastern Uruguay. Collecting was carried out on a monthly basis (May 2002 through April 2003). Drosophilids accounted for 0.84% (

5. Evolução e ecologia de tricomas em Bignonieae (Bignoniaceae): estruturas morfológicas de defesa anti-herbivoria? / Evolution and ecology of trichomes in Bignonieae (Bignoniaceae): morphological structures of anti-herbivory defense?
This thesis focused on the evolutionary-ecology of trichomes in the tribe Bignonieae (Bignoniaceae), and in the potential defensive role of these structures against herbivores. More specifically, we characterized four trichome morphotypes found in vegetative plant parts of representatives of the Bignonieae, as well as studied the macro-evolutionary patterns

6. Caracterização morfológica, fisiológica e bioquímica da Corticeira-do-banhado em condições de alagamento / Caracterização morfológica, fisiológica e bioquímica da Corticeira-do-banhado em condições de alagamento / Morphological, physiological and biochemical caracterization of Corticeira-do-banhado in flooding conditions / Morphological, physiological and biochemical caracterization of Corticeira-do-banhado in flooding conditions
The Erythrina crista-galli L., popularly known as corticeira-do-banhado, is a medium sized tree belonging to family Fabaceae, known especially for their vibrant colored flowers. The cork is listed as a plant immune to the court, by CONAMA, such is the devastation of their habitat and due to its importance in the restoration of riparian vegetation and restora

7. Alelopatia e bioprospecção em Rapanea ferruginea e Rapanea umbellata
Allelopathy is a process that involves primary or secondary metabolites produced by plants and microorganisms, which influences the growth and development of agricultural and biological systems. The intensity of plant allelopathic effects may depend on the hábitat, age and the biotic and abiotic conditions during the seasons in which they were collected. Wh

8. Implantação da piscicultura familiar com pescadores e agricultores assentados no Município de Lucena-PB
Fishing is a very important activity for the provision of protein, but as a result of the heavy pressure from extractive fishing and above the limits of carrying capacity of populations of commercial species, many stocks are at or above the limit of exploration, which has resulted in decreased populations of many animals, including driving some to extinction

9. Interações entre o predador Podisus nigrispinus (Heteroptera: Pentatomidae) e o parasitóide Palmistichus elaeisis (Hymenoptera: Eulophidae) / Interactions among the predator Podisus nigrispinus (Heteroptera: Pentatomidae) and the parasitoid Palmistichus elaeisis (Hymenoptera: Eulophidae)
The use of more than one natural enemy for pests control can increase the efficiency of the biological control, mainly, when those organisms act on different apprenticeships of the pests. The diversification of the beneficial fauna can reduce the population of herbivores and the disturbance of the ecosystems, increasing the local stability. The objective was

10. Vegetação de sub-bosque em monocultura de Eucalyptus saligna Sm. (Myrtaceae)
A modificação da paisagem e a fragmentação de habitats são consideradas ameaças à biodiversidade mundial. Áreas cobertas por vegetação primária ainda preservadas e unidades de conservação são insuficientes para garantir a conservação de espécies. Cultivos de florestas homogêneas passaram a ser considerados como possíveis habitats alternati

LEVANTAMENTO DAS POPULAÇÕES DE CALLICEBUS COIMBRAI KOBAYASHI &LANGGUTH, 1999 EM FRAGMENTOS DE MATA ATLÂNTICA NO SUL DO ESTADO DE SERGIPE, BRASIL. / SURVEY OF THE POPULATIONS OF CALLICEBUS COIMBRAI KOBAYASHI &LANGGUTH, 1999 IN FRAGMENTS OF THE ATLANTIC FOREST IN THE SOUTH OF THE BRAZILIAN STATE OF SERGIPE.
Coimbra-Filhos titi monkey (Callicebus coimbrai Kobayashi &Langguth, 1999) is an endangered, but poorly-known primate that inhabits remnants of the Atlantic Forest in the Brazilian states of Sergipe and Bahia (northern coast). The present study aimed to evaluate the effects of habitat fragmentation on the ecological characteristics and provide information on

12. Exploiting triatomine behaviour: alternative perspectives for their control
Living in close association with a vertebrate host and feeding on its blood requires different types of adaptations, including behavioural adjustements. Triatomines exhibit particular traits associated with the exploitation of their habitat and food sources and these traits have been the subject of intense analysis. Many aspects of triatomine behaviour have
