Variation In Nuclear Dna Content Across Environmental Gradients: A Quantile Regression Analysis, Charles A. Knight, David D. Ackerly Jan 2002

Variation In Nuclear Dna Content Across Environmental Gradients: A Quantile Regression Analysis, Charles A. Knight, David D. Ackerly

Biological Sciences

The nuclear DNA content of angiosperms varies by several orders of magnitude. Previous studies suggest that variation in 2C DNA content (i.e. the amount of DNA in G1 phase nuclei, also referred to as the 2C-value) is correlated with environmental factors, but there are conflicting reports in the literature concerning the nature of these relationships. We examined variation in 2C DNA content for 401 species in the ecologically diverse California flora in relation to the mean July maximum temperature, January minimum temperature, and annual precipitation within the geographical ranges of these species. Species with small 2C-values predominate in all environments. …


Calorimetric Study Of Block-Copolymers Of Poly(N-Butyl Acrylate) And Gradient Poly(N-Butyl Acrylate-Co-Methyl Methacrylate), A I. Buzin, M Pyda, P Costanzo, K Matyjaszewski, B Wunderlich Jan 2002

Calorimetric Study Of Block-Copolymers Of Poly(N-Butyl Acrylate) And Gradient Poly(N-Butyl Acrylate-Co-Methyl Methacrylate), A I. Buzin, M Pyda, P Costanzo, K Matyjaszewski, B Wunderlich

Chemistry and Biochemistry

The nanophase separation in diblock and triblock copolymers consisting of immiscible poly(n-butyl acrylate) (block A) and gradient copolymers of methyl methacrylate (MMA) and n-butyl acrylate (n BA) (block M/A) were investigated by means of their heat capacity, Cp, as a function of the composition of the blocks M/A and temperature. In all copolymers studied, both blocks are represented by their Cp and glass transition temperature, Tg, as well as the broadening of the transition-temperature range. The low-temperature transition of the blocks A is always close to that of the …


Two New Species Of Pectis (Asteraceae: Tageteae) From South America, David J. Keil Jan 2002

Two New Species Of Pectis (Asteraceae: Tageteae) From South America, David J. Keil

Biological Sciences

Pectis hassleri and P. pumila are new species, the former from the Gran Chaco area of Paraguay and the latter from southwester Encuador and northwestern Peru. Pectis hassleri differs from P. odorata by leaves that are glandular-punctaoten the adaxial as well as the abaxial surfaces, by longer and wider ligules of the ray florets, and by ray pappi of awns and shorter bristles. Pectis pumila differs from the closely related P. arida by its wider leaves and by its sessile or subsessile capitula with campanulatein volucresa nd obovatep hyllaries.A hexaploid chromosome count of 2n = 361 is newly reported for …


Antimicrobial Activity Of Plants Collected From Serpentine Outcrops In Sri Lanka, Nishanta Rajakaruna, Cory S. Harris, G. H. N. Towers Jan 2002

Antimicrobial Activity Of Plants Collected From Serpentine Outcrops In Sri Lanka, Nishanta Rajakaruna, Cory S. Harris, G. H. N. Towers

Biological Sciences

Thirty-two plant species collected from serpentine (ultramafic) soils in Sri Lanka were screened for antimicrobial properties against three Gram-positive and two Gramnegative bacteria, a non-acid fast bacterium, and the yeast, Candida albicans. Methanol extracts of 29 species belonging to 12 families were active against at least one microorganism. Activity against the Gram-positive and non-acid fast bacteria was common, however, only two taxa, Lantana camara L. (Verbenaceae) and a species of Phyllanthus L. (Euphorbiaceae), were active against the Gram-negative bacterium Pseudomonas aeruginosa. None of the species was active against the other Gram-negative bacterium, Escherichia coli, or C. albicans. Photoactivity was observed …
