Pyrogenic plants dominate many fire-prone ecosystems. Their prevalence suggests some advantage to their enhanced flammability, but researchers have had difficulty tying pyrogenicity to individual-level advantages. Based on our review, we propose that enhanced flammability in fire-prone ecosystems should protect the belowground organs and nearby propagules of certain individual plants during fir...

Paleolimnologists have utilized lake sediment records to understand historical lake and landscape development, timing and magnitude of environmental change at lake, watershed, regional and global scales, and as historical datasets to target watershed and lake management. Resurrection ecologists have long recognized lake sediments as sources of viable propagules ("seed or egg banks") with which ...

Although knowledge on dispersal patterns is essential for predicting long-term population dynamics, critical information on the modalities of passive dispersal and potential interactions between vectors is often missing. Here, we use mangrove propagules with a wide variety of morphologies to investigate the interaction between water and wind as a driver of passive dispersal. We imposed 16 combi...

peperomia pellucida leaf extract was characterized for its anticancer, antimicrobial, antioxidant activities, and chemical compositions. anticancer activity of p. pellucida leaf extract was determined through colorimetric mtt (tetrazolium) assay against human breast adenocarcinoma (mcf-7) cell line and the antimicrobial property of the plant extract was revealed by using two-fold broth micro-di...

recently, there have been more reports of cardiac valve infections due to the increasing number of intravenous (iv) drug abusers and chronic renal failure patients. among cardiac valves, tricuspid valve is most commonly affected in the course of endocarditis. appropriate management of these patients is a challenging and controversial issue in the field of cardiac surgery. treatment options in s...

BACKGROUND Use of plant resources and ecosystems practiced by indigenous peoples of Mesoamerica commonly involves domestication of plant populations and landscapes. Our study analyzed interactions of coexisting wild and managed populations of the pitaya Stenocereus pruinosus, a columnar cactus used for its edible fruit occurring in natural forests, silviculturally managed in milpa agroforestry ...

BACKGROUND There is a lack of standardized protocols for assessing the presence of indoor fungi. It is thus difficult to compare results from different studies or to measure the effect of indoor fungal presence on occupants. AIMS The aim of the present work was to evaluate the presence of airborne fungal propagules within a hospital taking into account the influence of environmental factors. ...

Infective endocarditis can complicate with ischemic stroke. Neurological complications develop in 20-40% of all patients with infective endocarditis. These are mainly due to vegetation embolism.This report represents a case of 30 years old female patient who presented with features of heart failure New York Heart Association (NYHA) class IV with infective endocarditis and left hemiparesis. On e...

On-farm production of arbuscular mycorrhizal [AM] fungus inoculum can be employed to make the benefits of the symbiosis more available to vegetable farmers. Experiments were conducted to modify an existing method for the production of inoculum in temperate climates to make it more readily adoptable by farmers. Perlite, vermiculite, and peat based potting media were tested as diluents of yard cl...
