TL;DR: This work states that ecosystem management groups should include functional diversity in their scheme and not just species richness, and that the diversity hypothesis and the mass ratio hypothesis do not contradict each other and instead reflect the two different sides of functional diversity and functional composition.

TL;DR: In this paper, the authors reviewed the productions and emissions of CH4, CO2, and N2O in reservoirs, and the environmental variables influencing CH4 and CO2 emissions were also summarized.

TL;DR: 24 hypotheses and models, which are influential in the international community concerning the relationship between plants and herbivores, were introduced and grouped into four categories according to plant defense strategies in the present review.

TL;DR: General characteristics of coral reef ecosystems and spectral features of different reef benthos have been summarized, based initially on a review of relevant literature in recent years.

TL;DR: A land cover classification system for land cover mapping for the estimation of carbon storage in ecosystems and the national environmental assessments is proposed and has been adopted in the Chinese national land cover database.

TL;DR: In this paper, the changes within the year, inter-annual changes trend and spatial variation of the mid-subtropical forest vegetation index during the recent 10 years are analyzed based on MODIS NDVI data from 2000-2011 with the spatial resolution of 250m.

TL;DR: This paper reviewed the current evidence of the impacts of drought on terrestrial ecosystems, with particular emphasis on the ways in which drought alters the biological, biogeophysical and biogeochemical processes underlying the interaction between the biosphere and the atmosphere.

TL;DR: In this article, the influence of mulch thickness on watermelon yield and water use efficiency and yield was investigated in two field experiments at Gaolan, Gansu, China.

TL;DR: In this article, the impact of increased nitrogen deposition on soil acidification is not well addressed highlighting the need for further attention to the issue, which can serve for maintaining sustainable forest and agricultural ecosystems.

TL;DR: Wang et al. as discussed by the authors assessed how agricultural activities in a reclamation wetland changed soil pH, soil electric conductivity, soil nutrient and soil particle size as compared to natural vegetation by using a combination of field experiments and lab analysis.

TL;DR: The influence of habitat change on the community structure of birds, the species and individual numbers in the lakeside developmental land of Thousand-Island Lake have been recorded since January 2009 till December 2010 and the total individual number of birds reduced 51.9%.

TL;DR: In this article, the effect of potassium zeolite on ammonium and ammonium ion retention in a saturated sandy loam soil in a laboratory condition was investigated, and the results showed that increasing the amount of applied zerosolite to soil causes reduction to the mobility of both nitrate and ion and enhancement of ion retention.

TL;DR: Wang et al. as discussed by the authors investigated how the accomplishment of the ecological projects affected the change of land use and land cover (LULC) types and their spatial distribution in Southwestern China.

TL;DR: The basic principle of RF was summarized and how RF handle complex data by modelling the geographical distribution of Yunan Pine, which was consistent with the multi-dimensional scaling plot that showed it was possible to separate the presences from the absences.

TL;DR: Analysis of spatiotemporal characteristics of vegetation cover changes and the factors that affect the changes in the core control area of the BTSSR using the time series of normalized difference vegetation index( NDVI)derived from a Moderate Resolution Imaging Spectro-Radiometer( MODIS) product MODIS02 B for the time period of2000—2012 provided scientific guidelines for the management of ecological restoration programs and future directions.

TL;DR: In this paper, the authors determined the proportions of different water sources drawn by selected dominant plant species, examined the consistence of this proportion for different plant species during the growth season, and investigated the water competition conditions among the selected dominant species.

TL;DR: The results reveal that domestic research falls into categories of basis theories and system construction: the study of the origin of ecological security; ecological security basic theory; ecological risk assessment; ecological system assessment; and land ecological security, which form the main knowledge groups of domestic ecological security research.

TL;DR: In this paper, the authors evaluated the effect of estuarine environmental gradient on phytoplankton communities in the Pearl River estuary during June 25 to July 2 of 2009 (wet season) and January 11 to 16 of 2010 (dry season).

TL;DR: In mountainous area, many factors such as the high spatial heterogeneity in land cover conditions and the topographic effect on remote sensing data acquisition significantly constraint the change detection by using remote sensing method as mentioned in this paper.

TL;DR: It is concluded that larger-scale assessment studies are still lacking, and assessment theories and methods are being developed, and EcoRA needs to make further efforts, especially in theoretical study, uncertainty analysis, integrated use of GIS software and comprehensive risk assessment at regional scale in the future work.

TL;DR: In this article, the temporal and spatial dynamics of land use in the Yangtze River Delta from 1980 to 2010 were analyzed supported by ArcGIS software, and a simple ecosystem service value estimation method was adopted to calculate the ecosystem servicevalue.

TL;DR: Based on simulated erosion plots with treatments of eight erosion depths (0, 10, 20, 30, 40, 50, 60 and 70 cm) and two sub-treatments of no fertilizer and chemical fertilizer situated in black soil region, northeast China, soil samples of the 0-20 cm layer in each plots were collected and several key soil biological parameters were determined as discussed by the authors.

TL;DR: In this paper, the authors summarized the contents of carbon dioxide emissions from tourism at different scales such as world, nation, region and unit, and indicated that there are progresses in the consistency of coefficients at global scale and diversity of coefficient at national, regional and unit scales, while the coefficients of developed countries and regions are higher than those of developing countries and region.

TL;DR: Based on graph-theoretic methods, this article evaluated the contribution of orchards to the whole network connectivity and its three fractions (intra, flux and connector), and then analyzed the species that could benefit the most from the habitat supplement.

TL;DR: The results suggest that the marine planktonic diatoms taxa were generally adapted to specific hydrological structure and biomass was a better ecological bio-indicator than abundance.

TL;DR: The drought resistance of plants is the sum of many physiological factors, and represents complex interactions among these factors, so it is a complicated physiological adjustment mechanism.

TL;DR: Wang et al. as discussed by the authors used an arched shed-air conditioning system, where covered drift sand thickness of 2.0m was measured and compared. And they found that the phreatic water under sand can go through sand layer and get to surface, which forms evaporation.

TL;DR: The results showed that in China, the reducing trend of surface solar radiation did not persist after the 1990, instead, an increasing trend had been observed since the late 1980s, and the trend and turning points of surfaceSolar radiation in China are consistent with the global trend.

TL;DR: This work investigated the species composition, density and biomass distribution, dominant species of zooplankton and water quality parameters in Dishui Lake, a newly formed lake with a fragile ecosystem and could be affected by external pollutant sources.

TL;DR: In this article, the vegetation net primary productivity (NPP) in Guangxi province from 2000 to 2011 was estimated using the light use efficiency model and the time-series NDVI of MODIS data.
