Objectives: • Understand the concepts of natural selection, heritable variation, and selection pressures • Become familiar with the experimental system in which we will measure natural selection (read this lab and the Natural History article “Just Lookin’ for a Home” which is posted on Blackboard before you come to lab). • Develop testable hypotheses regarding natural selection in the goldenrod...

The aim of this study is to analyze the differential proteins in MRSA ATCC 33591 treated with aqueous extract from Q. infectoria gall. Protein extracts were obtained from MRSA cells by sonication and were separated by 2D polyacrylamide gels. Protein spots of interest were extracted from the gels and identified using LC-ESI-QTOF MS. The concentration of Q. infectoria extract used for 2D-gel elec...

Our goal was to identify herbivory patterns from two insect guilds associated with Cnidoscolus quercifolius in a tropical deciduous forest in northeastern Brazil. We sampled four different habitats: (1) forest edge, (2) mesic (near to the perennial water source), (3) forest interior and (4) rupestrian fields. Habitat edge had lower leaf damage than rupestrian, mesic and forest interior habitats...

INTRODUCTION The worldwide increased bacterial resistance to antibiotics and the undesirable side effects associated with constant use of synthetic drugs has prompted the search for novel antimicrobial agents, particularly those manufactured from plants. This study is designed to ascertain the antibacterial potential of Rhus succedanea leaf gall extracts on the growth of gram-positive and gram-...

The organization of gall on the ovary ofSesamum indicum L induced by the gall midge, Asphondylia sesami Felt, not only affects biochemical equilibrium of the host but also causes disturbed vegetative growth and reduced seed-setting. The toxicity created by the gall maker induces the re-orientation of vasculature Cecidogenetic stimuli lead to excessive hypertrophy and hyperplasy forming the gall...

Candida albicans, one of the most dreadful fungal pathogens threatening humans, could not be easily prevented. The anticandidal activity of oak gall extract, Quercus infectoria (QIE), was investigated as a potential natural alternative to synthetic and chemical fungicides. QIE anticandidal potentiality was confirmed using both qualitative and quantitative assays. Cotton textiles were treated wi...
