13. ANTIFUNGAL POTENTIAL OF PLANT SPECIES FROM BRAZILIAN CAATINGA AGAINST DERMATOPHYTES
Trichophyton rubrum and Trichophyton mentagrophytes complex, or Trichophyton spp. are the main etiologic agents of dermatophytosis, whose treatment is limited by the high cost of antifungal treatments, their various side effects, and the emergence of resistance amongst these species. This study evaluated the in vitro antidermatophytic activity of 23 crude ex

14. First report of modern pollen deposition in moss polsters in a semiarid area of Bahia, Brazil
Recent studies have shown that pollen analyses of natural substrates can produce data valuable for understanding the local pollen productivity and dispersal, deposition, and preservation potential of pollen grains. In this study, we aimed to acquire novel information about the dynamics and preservation of pollen in Caatinga environment through the palynologi

15. Pollen types used by Centris (Hemisiella) tarsata Smith (1874) (Hymenoptera, Apidae) in the provisioning of brood cells in an area of Caatinga
The aim of this study was to identify, by sediment pollen analysis, the plant species used as floral resources for the provisioning of brood cells in Centris (Hemisiella) tarsata, in an area of Caatinga, within the municipality of Nova Soure, Bahia State, Brazil. The analysis of pollen contents from three brood cells revealed 11 pollen types, corresponding t

16. What is the role of exotic medicinal plants in local medical systems? A study from the perspective of utilitarian redundancy
Medicinal plants are an important aspect of local medical systems. The composition of a medicinal plant collection is influenced by cultural and environmental factors. Additionally, the functionality of a local medical system can be threatened by the replacement of native species with exotic ones, as well as by cultural factors such as the erosion of knowled

17. Effect of salt stress on the growth of Lippia gracilis Schauer and on the quality of its essential oil
This study evaluated the effect of salt stress on the growth of Lippia gracilis Schauer, a species native to the caatinga (shrublands) of Brazil and rich in essential oils, as well as on the quality of its oil. We exposed individuals of L. gracilis to NaCl, in the following concentrations, for a period of 40 days: 25 mM; 50 mM; 75 mM; and 100 mM. An addition

18. Bryophytes on rocky outcrops in the caatinga biome: a conservationist perspective
In the state of Paraíba, Brazil, there is an abundance of rocky outcrops, which are typical elements of the semi-arid landscape. Those outcrops provide refuge to species with morphological adaptations to stressful climates and to rare communities of plants, including bryophytes. Nevertheless, there have been no studies of bryophytes in such habitats in the

19. Alterações fisiológicas e bioquímicas em quatro espécies florestais do bioma caatinga submetidas a alagamento / Physiological and biochemical alterations in four forestry species of the caatinga biome subject to flooding
O nordeste brasileiro é caracterizado por possuir clima semi-árido, quente e seco. Ocupado predominantemente pelo Bioma Caatinga, que apresenta vegetação xerófila, de fisionomia e florística variada. Parte da Bacia Hidrográfica do São Francisco, nos estados de Alagoas e Sergipe, situa-se neste Bioma. No entanto, este apresenta componente vegetacional

20. Medicinal plants at the Sítio do Gois, Apodi, Rio Grande do Norte State, Brazil
Rural communities have accumulated knowledge about survival techniques in the midst of difficulties, such as ecological, economic or social, and one of the transformation spaces and extraction of resources to these communities is the natural vegetation and homegarden. The aim of this study was to list medicinal plants and characterize the use of these plants

21. Bioactivity and potential therapeutic benefits of some medicinal plants from the Caatinga (semi-arid) vegetation of Northeast Brazil: a review of the literature
Medicinal plants have been used in traditional medicine for several thousand years all over the world. In this sense, information from Brazilian ethnic groups on folk medicine have contributed to the discovery of pharmacological activities from various plant-derived agents potentially leading to the innovative drugs. The Caatinga (semi-arid) vegetation is a

22. Relocation of Croton sonderianus (Euphorbiaceae) seeds by Pheidole fallax Mayr (Formicidae): a case of post-dispersal seed protection by ants?
Although seed dispersal by ants might reduce seed predation near the parent plants, predation on discarded seeds clustered on nest refuse piles may reduce any initial benefit provided by seed removal. Here we examine the fate of Croton sonderianus seeds that were discarded by Pheidole fallax Mayr ants on their nest refuses in caatinga vegetation of northeast

23. Estudo comparativo de plantas alimentícias em comunidades rurais da caatinga pernambucana e paraibana: etnobotânica, potencial econômico e conteúdo nutricional. / Comparative study of food plants in rural communities of the caatinga of Pernambuco and Paraiba, ethnobotany, economic potential and nutritional content.
The wild plants represent an inexhaustible source of food yet unknown by the scientific community and the general population, but which are widely used by traditional communities in different ecosystems both in complementing their usual diet arising from agriculture, and in times of food scarcity. The research objective was to identify in two rural communiti
