Soil Characteristics of Four Juncus roemerianus Populations in Mississippi

Microsatellite markers for population studies of the salt marsh species Juncus roemerianus (Juncaceae)1

PREMISE OF THE STUDY Juncus roemerianus (Juncaceae) is a foundational species and ecosystem engineer of salt marshes in the Gulf of Mexico. These ecosystems provide coastal flood attenuation, nurseries for important species, and other ecosystem services, but are experiencing significant decline. Nuclear microsatellite markers were developed for J. roemerianus to study genetic diversity and popu...

Leaf Wand for Measuring Chlorophyll Fluorescence on Cylindrical Leaves and Its Application on Juncus roemerianus (Black Needlerush)

Chlorophyll fluorescence is a well established technique to rapidly and non-invasively determine photosynthesis parameters in plant leaves. It can be used in both laboratory and field settings, and frequently dark-adaptation of a leaf sample is called for. In the field, this can be accomplished on flat leaves using standard leaf clips supplied by instrument manufacturers. However, not all plant...

Survey of Imported Fire Ant (hymenoptera: Formicidae) Populations in Mississippi

Anatomical Structure Study of Aerial Organs in Four Populations of Urtica dioica L.

Urtica dioica L. is an Iranian native pharmacological plant for which little attention has been paid to the anatomical structure. Medical applications of this plant include diabetes therapy, digestive improvement, anemia and kidney disease therapy. Because climatic conditions can affect the anatomical structure which in turn affects pharmacological compositions, research on the anatomy of this ...
