Here we introduce a new model species, Silene colpophylla, that could facilitate research of sex chromosome evolution and sex-determining systems. This species is related to the well-established dioecious plant model Silene latifolia. Our results show that S. colpophylla is, similarly to S. latifolia, a male heterogametic species, but its sex chromosomes have evolved from a different pair of au...

Herbicides that are labeled for aquatic use often the foundation of vegetation management programs in United States because many these products, which registered by U.S. Environmental Protection Agency, effective, selective, and relatively inexpensive. Resource managers interested reducing synthetic herbicides considering alternative methods weed control. We evaluated effects acetic acid d-limo...

We investigated the use of stable C and N isotopic ratios as indicators of shifts in nutrient limitation of aquatic macrophytes in native Typha (Typha domingensis Pers.) and Cladium (Cladium jamaicense Crantz) communities growing along the well-established phosphorus enrichment gradient of Water Conservation Area 2A of the Florida Everglades. Both Typha and Cladium had significantly different d...

Larvae of. Culex tarsalis Coquillett and Culiseta inornata Williston are abundant in duck ponds within the San Joaquin freshwater marsh. Culex tarsalis are found year-round and Culiseta inornata are found during the winter months. Each duck pond has an area ofopen water ringed with emergent Scirpus californicus (bulrush) and Typha latifolia and Typha anpstifolia (cattails). Low densities of lar...

Where wetlands receive urban runoff, Typha spp. and other invasive plants often displace the native vegetation. We tested the ability of nutrients (N and P) to increase vegetative growth of T. 3 glauca (a hybrid of T. latifolia and T. angustifolia). In the greenhouse, 17 treatments revealed that T. 3 glauca required both N and P for growth, and total leaf length was most stimulated where a high...

AIM To evaluate the hepatoprotective activity of a hydroalcoholic extract of the bark of Anogeissus latifolia; in vitro in primary rat hepatocyte monolayer culture and in vivo in the liver of Wistar rats intoxicated by carbon tetrachloride (CCl(4)). METHODS In the in vitro study, a primary hepatocyte monolayer culture was treated with CCl(4) and extract of Anogeissus latifolia. Hepatoprotecti...
