Book Description
Emergent macrophytes are an integral part of prairie marshes and involved in many of the services that make these ecosystems valuable. Water depth and hydroperiod are two environmental variables that can influence the growth and nutrient content of emergent macrophytes. This study looked at the growth and nutrient content response of hybrid cattail (Typha x glauca) to water depth and hydroperiod in two prairie marshes in southern Manitoba, Canada. Above- and belowground samples of hybrid cattails were collected along a water depth gradient at Oak Hammock Marsh, Canada, and analyzed for biomass, total phosphorus, total nitrogen, total Kjeldahl nitrogen content, shoot height, and density. A second dataset was obtained from the Marsh Ecology Research Program (MERP) experiment, and used to determine the biomass and nutrient content response of the hybrid cattail following one or two years of drawdown.

Book Description
Broadleaf cattail, Typha latifolia is a species of cattail native to North America, while narrow-leaf cattail, Typha angustifolia is considered to be a non-native species originating in Europe. These two species hybridize to form the hybrid cattail, Typha x glauca. Narrow-leaf cattail and hybrid cattail are both considered invasive species and are managed throughout North America. This research project aims to understand the effects of Typha angustifolia and Typha x glauca on ecosystem structure and processes by comparing wetlands dominated by non-native narrow-leaf and hybrid cattail species to wetlands containing only native broadleaf cattail.

Book Description
The Anthropocene, with the ongoing global changes in climate, land use, acidity, and content of toxins, represents the greatest recent challenges for plants. Clonal plants mainly reproduce vegetatively/asexually, and offspring remain attached to the parent at least until establishment. Despite limited gene recombination and genetic diversity, clonal plants are widely distributed and play significant roles in various ecosystems worldwide. Clonal traits, such as resource sharing and signaling between connected ramets, selective positioning of ramets, reallocation of stored energy/nutrients between connected ramets, initiation of meristem banks in response to clonal integration, and trade-offs between clonal and sexual reproduction, might help clonal plants adapt to different environmental conditions. The expression, fitness effects, and evolution of clonal traits can be influenced by environmental changes, which can be efficiently inherited and affects offspring performance, i.e., clonal parental effect. These adaptations may contribute to the survival, competition, invasiveness, and spread of clonal species in response to global climate change in the Anthropocene, from individuals to ecosystems. Understanding the capacity of clonal species to survive and adjust to changing environments is requisite but limited. Specifically, the unique traits of clonal plants have been underestimated, and their contribution to population, community, and ecosystem dynamics is unclear. The roles of clonality in ecosystem functioning (e.g., carbon storage, carbon, nitrogen and phosphorus cycling, water and soil conservation, and water purification) need to be further explored. The contribution of clonal growth in plant invasiveness and community invisibility also needs to be addressed. Hence, there is an urgent need for more in-depth studies investigating the adaptation and evolution, mechanisms, functioning, and approaches of plant clonality to global change and invasiveness at different levels.

Book Description
Coastal wetlands are under a great deal of pressure from the dual forces of rising sea level and the intervention of human populations both along the estuary and in the river catchment. Direct impacts include the destruction or degradation of wetlands from land reclamation and infrastructures. Indirect impacts derive from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. As sea level rises, coastal wetlands in most areas of the world migrate landward to occupy former uplands. The competition of these lands from human development is intensifying, making the landward migration impossible in many cases. This book provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide, and suggestions for their management. In this book a CD is included containing color figures of wetlands and estuaries in different parts of the world.

Book Description
As cities develop, more land is converted into impervious surfaces, which do not allow water to infiltrate. Careful urban planning is needed to ensure that the hydrologic cycle and water quality of the catchment areas are not affected. There are techniques that can attenuate peak flow during rain events and reduce the amount of metals, nutrients, and bacteria that enter the urban water cycle. This brief gives a short introduction on bioretention systems and documents the effectiveness of some 36 plant species in removing water pollutants. A summary on the maintenance requirements is also presented.
