13. Caatinga Tree Wood Anatomy: Perspectives on Use and Conservation
ABSTRACT This work describes the anatomical analysis of the wood of four Caatinga tree species in order to determine the anatomical characteristics necessary for species segregation in functional groups, to relate them to the regional environmental conditions, as well as to infer about their management and conservation. Qualitatively, the species showed pecu

16. HUNTING ACTIVITIES IN THE SEMIARID POTIGUAR UNDER THE STUDENTS PERSPECTIVE
Resumo Em áreas de Caatinga, a caça é considerada uma ameaça à fauna e ao equilíbrio ecológico, sendo o estudo da atividade cinegética relativamente importante para elaboração de estratégias de conservação. Baseado nesta premissa, esta pesquisa visa identificar os animais silvestres capturados, suas formas de uso e técnicas de caça em dois mun

17. Contribution of Litter and Leaf Decomposition of Byrsonima gardneriana
ABSTRACT The litter in tropical ecosystems is one of the compartments responsible for the transference of nutrients to the soil, having great importance for the conservation and maintenance of biodiversity. Thus, this study aimed to quantify the contribution and stock of litter and the leaf decomposition rate of Gardneriana byrsonima A. Juss (murici) in two

18. The conservation of native priority medicinal plants in a Caatinga area in Ceará, northeastern Brazil
ABSTRACT Much of the Brazilian semiarid region faces a considerable process of degradation of natural resources, and ethnobotanical studies have collaborated with important information about the use and traditional knowledge, serving as a tool to design conservation strategies of native plant species. Thus, this study aimed to determine medicinal species mer

19. Temporal evaluation of the Conservation Priority Index for medicinal plants
ABSTRACT We investigated, through a temporal comparison, the extraction of non-timber forest resources by quantitatively analyzing the Conservation Priority Index (CPI). The study focused on the Fulni-ô Indigenous Territory, in the municipality of Águas Belas, PE (Northeast Brazil), which is characterized by caatinga vegetation (seasonal dry forest). Infor

21. Response of an endangered tree species from Caatinga to mycorrhization and phosphorus fertilization
Schinopsis brasiliensis is an endangered tree species found in the Caatinga biome. It presents a characteristic slow development and difficult propagation, although it has been traditionally exploited in the region. Application of arbuscular mycorrhizal fungi (AMF) and phosphorus (P) fertilization may be beneficial to S. brasiliensis development at the seed

22. 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

23. Taxonomic revision of Pseudolaelia Porto & Brade (Laeliinae, Orchidaceae)
Pseudolaelia is a genus endemic to eastern Brazil. The species are often epiphytes on Velloziaceae or are saxicolous, predominantly on granitic and gneissic outcrops (inselbergs) in the Atlantic Forest and, less often, in the campos rupestres (dry, rocky grasslands) of the cerrado (savanna) and caatinga (shrublands). The genus is characterized by homoblastic
