Suurten tietomassojen käsittely ja analysointi on tietokantojen, WWW:n ja satelliittijärjestelmien takia yhä haastavampaa. Miljoonia tietueita sisältävien tietovarastojen hahmotus ei ole manuaalisin keinoin käytännöllistä tai edes mahdollista. Myös paikkatiedon määrä ja saatavuus on lisääntynyt muun tiedon mukana mm. satelliittipaikannuksen, karttapalvelujen ja muiden paikkatietojärjestelmien a...

A nomenclatural revision of fifteen taxa of Xyris (Xyridaceae) described by L.A. Nilsson (1892) is presented as part of a taxonomic revision of the genus in Brazil. All the protologues and type collections of these taxa were studied. The type collections were examined in the respective herbarium collections where they are preserved and complemented by images available on herbarium websites and ...

The distribution and population sizes of Sorbus cambrensis (Welsh Whitebeam) S. stenophylla (Llanthony (Rosaceae) are revised based on field surveys. About 224 trees occur in eight populations/subpopulations (including the Llanthony Valley), about 96 five populations/subpopulations. Morphological analysis leaves confirmed two species were different showed some variation within each species.

Pollen from the Acacia has been reported as an important source of pollinosis in tropical and subtropical regions of the world. The aim of this study was to characterize the IgE binding protein of Acacia farnesiana pollen extract and evaluate cross-reactivity with the most allergenic pollens. In this study, pollen extract was fractionated by SDS-PAGE and the allergenic profile was determined by...

Exploiters of protection mutualisms are assumed to represent an important threat for the stability of those mutualisms, but empirical evidence for the commonness or relevance of exploiters is limited. Here, I describe results from a manipulative study showing that an orb-weaver spider, Eustala oblonga, inhabits an ant-acacia for protection from predators. This spider is unique in the orb-weaver...

The aim of this study is to determine the effect of methanol crude leaves extract and aqueous fraction of Acacia nilotica on liver enzymes and lipid profiles of alloxan induced diabetic Wistar rats. Diabetes was induced by a single intraperitoneal injection of alloxan dissolved in 0.9%v/v cold normal saline solution at a dose of 150 mg/kg body weight, after which the rats were randomly divided ...

Xanthomonas axonopodis punicae is the causative agent of Bacterial blight of Pomegranate that is known to cause yield loss up to 70-90%. The primary disease management method involves mainly use of chemical pesticides. In present investigation the antibacterial activity of extracts of Acacia nilotica, Datura metel, cow urine and butter milk against Xanthomonas axonopodis punicae was studied by ...

Study was aimed to evaluate the possible antisecretory and antiulcer activity of crude bark extract of Acacia catechu and its action against indomethacin an non steroidal anti inflammatory drug (NSAID) plus pyloric ligation induced gastric ulcers in rats. Administration of crude extract of Acacia catechu (400mg/kg/day p.o.) significantly reduced ulcer index when compared with indomethacin induc...

The immunomodulatory effect of aqueous extract of Acacia catechu commonly known as Katha or Karangali was studied at two doses of 5 mg/kg and 50 mg/kg orally. The effect was studied in neutrophil adhesion test, mice lethality test, carbon clearance assay, cyclophosphamide induced neutropenia, serum immunoglobulin levels and the heamagglutination test. Acacia catechu extract showed an increase i...
