Species-specific SSR alleles for studies of hybrid cattails (Typha latifolia x T. angustifolia; Typhaceae) in North America.
UNLABELLED PREMISE Studies of hybridizing species are facilitated by the availability of species-specific molecular markers for identifying early- and later-generation hybrids. Cattails are a dominant feature of wetland communities, and a better understanding of the prevalence of hybrids is needed to assess the ecological and evolutionary effects of hybridization. Hybridization between Typha...
متن کاملPatterns, Mechanisms, and Ecological Implications of Cattail (typha Spp.) Dominance in Great Lakes Wetlands
Many wetlands of the Great Lakes region are increasingly dominated by species of cattails, including the native Typha latifolia, the introduced Typha angustifolia, and their hybrid Typha glauca. Cattails are observed to form dense stands of live and dead biomass that may reduce plant diversity and compromise wetland habitat value. Cattail expansion has been used as an indicator of environmental...
متن کاملPhytotoxicity of atrazine, S-metolachlor, and permethrin to Typha latifolia (Linneaus) germination and seedling growth.
Phytotoxicity assessments were performed to compare responses of Typha latifolia (L.) seeds to atrazine (only) and atrazine + S-metolachlor exposure concentrations of 0.03, 0.3, 3, and 30 mg L(-1), as well as permethrin exposure concentrations of 0.008, 0.08, 0.8, and 8 mg L(-1). All atrazine + S-metolachlor exposures resulted in significantly reduced radicle development (p < 0.001). A stimulat...
متن کاملSynchrotron study of metal localization in Typha latifolia L. root sections.
Understanding mechanisms that control plant root metal assimilation in soil is critical to the sustainable management of metal-contaminated land. With the assistance of the synchrotron X-ray fluorescence technique, this study investigated possible mechanisms that control the localization of Fe, Cu, Mn, Pb and Zn in the root tissues of Typha latifolia L. collected from a contaminated wetland. Me...
متن کاملTypha latifolia and Cladium jamaicense litter decay in response to exogenous nutrient enrichment
The role of nutrient availability in the decay of Typha latifolia and Cladium jamaicense litter and associated microbial responses were studied under controlled experimental conditions. The experimental setup consisted of three 14 m mesocosms: (i) an experimentally enriched (N&P) mesocosm containing organic soil, (ii) a mesocosm with organic soil but no external enrichment, and (iii) a mesocosm...
