Water pollution, especially eutrophication, has become a serious world-wide problem in recent years. On the other hand, forage is in short supply during the dry season in Asia (especially in Southeast Asia). The purpose of this paper is to describe the development of new forage resources from among aquatic plants. In conclusion, it is suggested that three emergent plants (Zizania latifolia Turcz., Pontederia cordata L., Paspalum distichum L.) are useful as new forage species because of their absorptive ability for nitrogen and phosphorus from eutrophic water and their superior feeding value following ensiling.

Biodiversity is all the living species that inhabit the planet: plants, animals, microorganisms, but also their genetic diversity and all the ecosystems in which they live. The preservation of biodiversity is vital, because the organisms that constitute it participate in the major ecological cycles of air, soil and water It is today recognized for its intrinsic value and for the functions it provides in ecosystems. The grassland and the hedges that surround them play a key role in carbon storage, water purification, biodiversity and the typicity of landscapes. They partly provide the plants necessary for feeding herds of herbivores (cattle, …

Sustainability of communal rangelands has become a major concern at national and international levels because land use conflicts and associated social conflicts allows for over-utilization of selected species making a high pressure on them and given away their places to species with no use at all becoming lands degraded and unproductive. The objective of the study was to determine floristic composition and native plant uses by local peasants. The range surface is of 4262 ha, belongs to the communal land ‘El Limon’, in Tepalcingo, Morelos, Mexico, and it is within the Natural Reserve Area “Sierra de Huautla”. Native vegetation is …

Modelling Grassland Ecosystems, J. H. M. Thornley
IGC Proceedings (1997-2023)
In this contribution a view of the promise and difficulties of modelling grassland is given. This is largely centred around work with a grassland ecosystem simulator known as the Hurley Pasture Model.
A brief introduction sets forth possible reasons for building a large ecosystem model, and stresses the importance of modelling objectives. It is suggested that a model is de rigeur for any research programme which aims to take a firm grasp of the complex responses of grassland. Mechanistic models are required to provide the understanding needed for intelligent and flexible management of grassland, whatever the prevailing environmental or economic …

The distribution of flowering across the growing season is governed by each species’ evolutionary history and climatic variability. However, global change factors, such as eutrophication and invasion, can alter plant community composition and thus change the distribution of flowering across the growing season. We examined three ecoregions (tall-, mixed, and short-grass prairie) across the U.S. Central Plains to determine how nutrient (nitrogen (N), phosphorus, and potassium (+micronutrient)) addition alters the temporal patterns of plant flowering traits. We calculated total community flowering potential (FP) by distributing peak-season plant cover values across the growing season, allocating each species’ cover to only those …
