Predizendo riqueza de espécies de plantas com imagens de satélite, no maior núc...
Medeiros, Edna Samara e SilvaThe assessment of biodiversity has been recognized as an indicator of ecosystem health for several initiatives worldwide. Satellite remote sensing (SRS) have introduced tools that facilitate the search for information related to plant diversity. With this perspective, this study aimed to verify if spectral variables, from Landsat satellite, can be used as plant species diversity indicators in the Caatinga, the ...
Cultivo in vitro e aclimatização de Epidendrum cinnabarinum Salzm. ex Lindl. (O...
Santos, Lucinalva Azevedo dosThe target species of this study, Epidendrum cinnabarinum Salzm, besides having high ornamental potential, has a disjunct distribution between rocky outcrops in Northeast region, with small populations characterized by large interpopulation genetic differences, which makes the specie genetic integrity being threatened. In vitro cultivation techniques propitiate to obtain a large quantity of seedlings in limited...
Biologia reprodutiva e citogenética de espécies simpátricas de Croton L. (Eupho...
Santos, Amanda de SouzaThe Croton genus often presents itself in plant communities with several sympatric species without clear evidence of interspecific hybridization. Aiming to evaluate the existence of reproductive isolation barriers and potential hybridization between these species, it was evaluated different aspects of the reproductive biology of three sympatric species of Croton (C. heliotropiifolius, C. jacobinensis e C. urtic...
Estruturação de comunidades de aves em uma paisagem urbanizada da floresta atlâ...
Enedino, Thayz RodriguesCurrently the Brazilian Atlantic Forest is considered one of the world's biodiversity repositories, however fragmentation, habitat loss, strong urbanization and other human disturbance have degraded its rich biological heritage and altered ecological processes that ensure their persistence. Paraiba remain some fragments of forests that are protected by law, but little is known about the level of change in the s...
Diversidade funcional em uma comunidade de floresta úmida: Testando fatores abi...
Gomes, José Leonardo dos SantosAbiotic factors can act as environmental filters at the local level and influence the establishment, distribution and functional diversity in plant communities in a rainforest, with this premise the present study was carried out at Mata do Pau Ferro State Park, Paraíba, Northeast, Brazil. The functional diversity was calculated using an index based on dendrograms and from eight functional attributes: Specific F...
Adubação orgânica na fertilidade do solo, trocas gasosas e componentes de produ...
Malaquias, Jardelio PauloTo increase the cultivation of organic melon, especially in Paraíba, there is some difficulties, lack of technical information in relation to crop management. Thus, the aim of this experiment was to determine the influence of nitrogen, from cattle manure and goat on soil fertility, gas exchange, foliar N, P and K, productivity, physical characteristics and mineral composition yellow melon in Entisol. The experi...
Influência do entorno dos reservatórios no estado trófico e na distribuição de ...
Silva, Kelly Dayane Pereira daThis study was to analyze the use and occupation of the land and its relation to water quality and to assess the distribution of diatoms in the surface sediment of five aquatic ecosystems and their trophic state (catchment area of the Mamanguape River - Paraíba, Brazil). For making the maps of land use and occupation was used buffer of 100 m in accordance with Law 12,651/2012 of the Forest Code. Between Septemb...
Potencial de mineralização de carbono e nitrogênio em solos do Semiárido Paraib...
Barbosa, Maria Aparecida da SilvaThe potential for mineralization of organic matter is an essential parameter for understanding the dynamics of C and N in the soil, especially when it emphasizes the semi-arid soils where there’s lacks of information about this phenomenon. This study aimed to evaluate the potential mineralization of C and N in 26 Paraíba semiarid soils. In incubation columns, respective samples to 26 Paraíba semiarid soils were...
Estado nutricional do abacaxizeiro „Pérola‟ adubado com NPK e enxofre
Rodrigues, João Batista BelarminoAlthough is important there are no basic information about fertilization and mineral nutrition, at example of response curves and critical levels for the 'Pérola' pineapple in the main producing municipalities in the Paraiba State. The objective of this study was to evaluate the effects of application of N, P, K and S rates on the nutritional status, and to determine the critical levels of their nutrients for t...
p−parabolic submanifolds in certain spacetimes: rigidity, uniqueness and non-ex...
Roing, FernandaIn this work we present rigidity and uniqueness results for parabolic and stable constant mean curvature hypersurfaces immersed in Generalized Robertson-Walker and Standard Static spacetimes. We obtained some conditions under which a hypersurface in these ambiences must be parabolic, as well as stable. In order to achieve the uniqueness results, we used some cut-o functions coming from the parabolicity jointly ...
