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.
A detailed account of the biology and ecology of vascular wetland plants and their applications in wetland plant science, Wetland Plants: Biology and Ecology presents a synthesis of wetland plant studies and reviews from biology, physiology, evolution, genetics, community and population ecology, environmental science, and engineering. It provides a
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.
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. - Includes a CD containing color figures of wetlands and estuaries in different parts of the world.
Small enough to carry in a backpack, this comprehensive guide explores the many diverse natural communities of Michigan, providing detailed descriptions, distribution maps, photographs, lists of characteristic plants, suggested sites to visit, and a dichotomous key for aiding field identification. This is a key tool for those seeking to understand, describe, document, conserve, and restore the diversity of natural communities native to Michigan.
Winner of the J. B. Jackson Prize from the Association of American Geographers Three centuries ago, the Los Angeles River meandered through marshes and forests of willow and sycamore. Trout spawned in its waters and grizzly bears roamed its shores. The bountiful environment the river helped create supported one of the largest concentrations of Indians in North America. Today, the river is made almost entirely of concrete. Chain-link fence and barbed wire line its course. Shopping carts and trash litter its channel. Little water flows in the river most of the year, and nearly all that does is treated sewage and oily street runoff. On much of its course, the river looks more like a deserted freeway than a river. The river's contemporary image belies its former character and its importance to the development of Southern California. Los Angeles would not exist were it not for the river, and the river was crucial to its growth. Recognizing its past and future potential, a potent movement has developed to revitalize its course. The Los Angeles River offers the first comprehensive account of a river that helped give birth to one of the world's great cities, significantly shaped its history, and promises to play a key role in its future.
