AbstractAbstract
[en] The semi-arid grasslands in Inner Mongolia (IM) are under increasing stress owing to climate change and rapid socio-economic development in the recent past. We investigated changes in land cover/land use and landscape structure between 1992 and 2004 through the analysis of AVHRR and MODIS derived land cover data. The scale of analysis included the regional level (i.e. the whole of IM) as well as the level of the dominant biomes (i.e. the grassland and desert). We quantified proportional change, rate of change and the changes in class-level landscape metrics using the landscape structure analysis program FRAGSTATS. The dominant land cover types, grassland and barren, 0.47 and 0.27 million km2, respectively, have increased proportionally. Cropland and urban land use also increased to 0.15 million km2 and 2197 km2, respectively. However, the results further indicated increases in both the homogeneity and fragmentation of the landscape. Increasing homogeneity was mainly related to the reduction in minority cover types such as savanna, forests and permanent wetlands and increasing cohesion, aggregation index and clumpy indices. Conversely, increased fragmentation of the landscape was based on the increase in patch density and the interspersion/juxtaposition index (IJI). It is important to note the socio-economic growth in this fragile ecosystem, manifested by an increasing proportion of agricultural and urban land use not just at the regional level but also at the biome level in the context of regional climate change and increasing water stress.

AbstractAbstract
[en] Using published data on the responses of individual species to ozone, 54 EUNIS (European Nature Information System) level 4 communities with six or more ozone-sensitive species (%OS) and c. 20% or more species tested for ozone sensitivity, were identified as potentially ozone-sensitive. The largest number of these communities (23) was associated with Grasslands, with Heathland, scrub and tundra, and Mires, bogs and fens having the next highest representation at 11 and 8 level 4 communities each respectively. Within the grasslands classification, E4 (Alpine and sub-alpine grasslands), E5 (Woodland fringes and clearings) and E1 (Dry grasslands) were the most sensitive with 68.1, 51.6 and 48.6%OS respectively. It is feasible to map the land-cover for these and other communities at level 2, but it may not be currently possible to map the land-cover for all communities identified to be ozone-sensitive at levels 3 and 4. - Grassland communities such as alpine and sub-alpine grasslands have the highest potential sensitivity ozone, based on the responses of their component species

AbstractAbstract
[en] Activities associated with timber harvesting have occurred within floodplain forests in the southern United States for nearly two hundred years. However, it is only in the last ten years that any information has become available about the effects of harvesting on the ecological functions of this valuable resource. Hydrology is the driving influence behind all ecological processes in floodplains and, in most cases, timber harvesting alone has little long-term effect on hydroperiod. However, there may be some instances where logging roads, built in association with harvest sites , can alter hydroperiod to the extent that vegetation productivity is altered positively or negatively. There is no documentation that harvesting followed by natural regeneration represents a threat to ground or surface water quality on floodplain sites, as long as Best Management Practices are followed. Harvested floodplains may increase or have little effect on decomposition rates of surface organic matter. The nature of the effect seems to be controlled by site wetness. Data from recently harvested sites (i.e. within the last ten years) suggest that vegetation productivity is maintained at levels similar to that observed prior to harvests. During the early stages of stand development vegetation species composition is heavily influenced by harvest method. Similarly, amphibian populations (monitored as bioindicators of ecosystem recovery) seem to rebound rapidly following harvests, although species composition may be different. 40 refs, 3 figs

AbstractAbstract
[en] The rhizosphere provides a special environment for microorganisms. As such, emergent aquatic plants play an important role in wetlands. However, due to the sampling methods, it is difficult to obtain sediment samples attached to specific sections of roots. Here, we developed a sampling method for segmented acquisition of sediment and in situ detection of environmental factors from the rhizosphere. This method can be particularly useful for emergent aquatic plants with rhizomatic root systems. (paper)

AbstractAbstract
[en] Although our understanding of environmental risk assessment in temporary wetlands has been improved by the use of multi-species toxicity testing, we still know little of how landscape variables mediate the strength of, and recovery from, anthropogenic stress in such ecosystems. To bridge this research gap, we provide a theoretical framework of the response of temporary wetlands to anthropogenic disturbance along a habitat-isolation continuum based on island biogeography theory, landscape ecology and dispersal and colonization strategies of temporary wetland organisms. - Environmental risk assessment in temporary wetlands may benefit from consideration of island biogeography theory and landscape structure

AbstractAbstract
[en] The Albeni Falls Interagency Work Group was actively involved in implementing wildlife mitigation activities in 2000. The Work Group met each quarter to discuss management and budget issues affecting Albeni Falls wildlife mitigation. Members of the Work Group protected a total of 1,242 acres of wetland habitat in 2000. The total amount of wildlife habitat protected for Albeni Falls mitigation is approximately 4,190 acres (4,630 Habitat Units). Approximately 16% of the total wildlife habitat lost has been mitigated. Land management activities were limited in 2000 as protection opportunities took up most staff time. Administrative activities increased in 2000 as funding was more evenly distributed among Work Group members. As a result, implementation is expected to continue to increase in the coming year. Land management and monitoring and evaluation activities will increase in 2001 as site-specific management plans are completed and implemented
