A study to reveal spatial distribution patterns in four characteristic dry forest tree species was undertaken in six one-hectare plots in the Cerros de Amotape National Park, northwestern Peru. The modified Ripley’s K statistic was used. Eriotheca ruizii (K. Schum.) A. Robyns (Bombacaceae), Bursera graveolens (Kunth) Triana & Planch. (Burseraceae), Caesalpinia glabrata Kunth (Leguminosae) and C...

Coriolopsis rigida was isolated as an endophytic fungus from the medicinal plant Cochlospermum regium. The cultivated on solid media containing rice or pineapple crown bran for analyzing production of extracellular enzymes. activities lipase, β-xylosidase, pectinase, fructosyltransferase (FTase), invertase, α-amylase and total cellulolytic (FPase) were determined. showed positive activity all e...

Diurnal and seasonal patterns of leaf gas exchange and water relations were examined in tree species of contrasting leaf phenology growing in a seasonally dry tropical rain forest in north-eastern Australia. Two drought-deciduous species, Brachychiton australis (Schott and Endl.) A. Terracc. and Cochlospermum gillivraei Benth., and two evergreen species, Alphitonia excelsa (Fenzal) Benth. and A...

During the last few decades the search for medical treatments based on alternative medicine has increased significantly, making knowledge of the plants commonly used as folk medicines extremely important. The plant Cochlospermum regium, a member of the Cochlospermaceae found in the Brazilian cerrado (a type of savanna), is known to have high depurative activity and to be effective not only in t...

The natural fiber market has been growing extraordinarily. Hereupon the current work presents of periquiteira tree Cochlospermum orinocense Amazon forest. chemical composition, physical aspects, morphology, thermal and mechanical properties this will be discussed. stability samples was about 200 °C. decomposition cellulose hemicelluloses in fibers occurred at 300 ºC above, while degradation hap...

The synthesis of ecofriendly nanoparticles is evergreen branch of nanoscience for biomedical application. In the present study biosynthesis of silver nanoparticles and its activity on bacterial pathogens were carried out. SNPs were rapidly synthesized using leaf extract of medicinal plant Cochlospermum religiosum and the formation of nanoparticles was observed within two minutes. The results re...

Seasonally dry forests in the neotropics are heavily threatened by a combination of human disturbances and climate change; however, the severity of these threats is seldom contrasted. This study aims to quantify and compare the effects of deforestation and climate change on the natural spatial ranges of 17 characteristic tree species of southern Ecuador dry deciduous forests, which are heavily ...
