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...

Wetland grasses and grass-like monocots are very important natural remediators of pollutants. Their genetic improvement is an important task because introduction of key transgenes can dramatically improve their remediation potential. Tissue culture is prerequisite for genetic manipulation, and methods are reported here for in vitro culture and micropropagation of a number of wetland plants of v...

Stable carbon and nitrogen isotope signals in plant tissues integrate plant-environment interactions over long periods. In this study, we hypothesized that humid alpine life conditions are narrowing the scope for significant deviations from common carbon, water and nitrogen relations as captured by stable isotope signals. We explored the variation in δ(13)C and δ(15)N in 32 plant species from t...

Laotris luzulae Godfray, sp. nov. is described in the small genus Nixon, 1943, (Braconidae, Alysiinae, Dacnusini) from five specimens reared Cerodontha silvatica (Groschke, 1957) (Diptera, Agromyzidae) mining Luzula sylvatica (Huds.) Gaudin (Juncaceae) Devon and Gloucestershire southwest of Great Britain. Six further Somerset caught as adults 1950s are also noted. It differs morphologically thr...
