Urban public green space (PGS) provides a wealth of ecological and social benefits, and is the key for sustainable urban development and human well-being satisfaction. A comprehensive evaluation is an important basis for PGS refined governance and planning. However, few studies have comprehensively explored the fine dimension of PGS quality, accessibility, and population, for the evaluation of accessible

Exploring the composition of soil organic carbon (SOC) and aggregate stability over a range of elevations is essential to evaluate the stability of SOC and the conversion of carbon source or sink of mountain ecosystems. However, information of those changes in mountain ecosystems in arid and semi-arid regions is still scarce to date. In this study, we estimated the response of SOC stability along elevation

We studied the differentiation among plant communities of deciduous broadleaved and mountain coniferous forests in terms of functional diversity and identity at a regional scale (northern and central Greece). We asked if patterns of functional differentiation among communities are consistent between the overstorey and understorey layers and if they can be influenced by deep past environmental conditions

Coralligenous reefs are typical underwater seascapes of the Mediterranean Sea and are ranked among the most relevant ecosystems of the basin and a pole of biodiversity. For their critical importance for ecosystems conservation, coralligenous reefs are included among the indicators that should be assessed under the Marine Strategy Framework Directive (MSFD). However, information regarding their spatial

Common approaches to estimating habitat quality are habitat suitability indices, which are often subjective. We propose a quantitative definition of habitat quality as the percentage of selected habitat that has a high probability of contributing to population growth. Using this definition, we created a habitat quality index based on spatial projections of habitat selection and survival probabilities

Maize (Zea mays L.) is a staple food in most parts of the world, and is also one of the most important food crops in China. Frequent occurrences of drought events can lead to summer maize drought disasters. The air relative humidity has the predominant superiority in spatio-temporal continuity compared to precipitation. In this study, meteorological data, phenophase observations, and disaster records

Field sandbur (Cenchrus spinifex Cav.) is an annual grass native to North America that has spread widely in South America, Europe, Asia, Australia and other regions, reducing crop and grassland productivity. In recent decades, global climate change and human activity have been linked to the spread of C. spinifex and its impact on ecosystem and biodiversity. In order to characterize the role of climate

Restoring degraded rivers requires initial assessment of the fluvial landscape to identify stressors and riverine features that can be enhanced. We associated local-scale river habitat data collected using standardized national monitoring tools with modeled regional water temperature and flow data on mid-sized northwest U.S. rivers (30–60 m wide). We grouped these rivers according to quartiles of their

As a prominent component of the terrestrial biosphere, soil nematodes constitute a potential indicator for biomonitoring systems. Although nematodes respond to environmental variables or gradients, the mechanism and reason of changes in nematode assemblages with the retrogression of grasslands induced by overgrazing remain poorly understood. This study aimed to comprehensively assess the response of

With immense impact on coastal ecosystems' function, especially on nutrient cycle, Spartina alterniflora has become the most importantly invasive species in coastal wetland of China. However, the alternation of sulfur level and transformation between different inorganic sulfur (IS) fractions caused by the plant are poorly understood. In order to study the effect of S. alterniflora invasion and growth

Monitoring how plant biomass changes with environmental conditions is critical for evaluating ecosystem carbon storage and understanding the underlying mechanisms of carbon dynamics. Usually destructive methods require a lot of time and cost. And the non-destructive methods to repeatedly estimate the biomass of herbaceous plants across large scale environmental conditions are still limited. Leymus

Maintaining the water balance of soil-vegetation systems is necessary for the ecological restoration of desertified regions. However, the major processes controlling water balance after revegetation remains unclear.

This study analyses the effects of climate change on habitat suitability and vulnerability in four categories of deciduous

Drought is complex geographical elements, which endangers China's food security, with coexistence of spatial and temporal heterogeneity and similarity. Thus, the recent abnormal characteristics of Chinese droughts warrant further study. This paper proposes a three-step framework to identify the spatiotemporal evolution characteristics of drought events in China Mainland, using the standardized precipitation

Global warming has boosted vegetation growth to a large extent, but this stimulation effect has significantly weakened in recent years. Among the set of possible driving forces, the asymmetric daytime and nighttime warming effect has been largely neglected. To improve our understanding on the relationship between vegetation growth and global warming, this study tries to attribute the respective effects

Upwelling and the El Niño “Southern Oscillation” (ENSO) are recurrent climatic phenomena in the southeastern Pacific Ocean that severely affect the reproduction and growth of pelagic fish populations. However, there are not long-term growth data from demersal fish populations to test these interconections in a long-term analysis. For this reason, a first extensive growth chronology was reconstructed

Tourism ecological security (TES) is an essential component and basic guarantee of the tourism regional system, and it is of great significance for scientific measurement of the operational status of a regional tourism ecological security system. The study focuses on the “quality” of tourism ecological security that has been neglected in the previous literature. From the perspective of system efficiency

Arbuscular mycorrhizal (AM) fungi are key players in the soil carbon (C) and nitrogen (N) cycles; on the one hand, AM fungi have been influenced by global changes, while on the other hand, they are involved in shaping the future climate. However, few field studies have combined AM fungi with both elevated temperatures and N deposition to examine their potential combined effects on the stocks of soil

The East China Sea (ECS) is the most important fishing ground in China. Field observations have always found no positive correlation between phytoplankton stocks and zooplankton biomass in the ESC. It has been suggested that under eutrophic conditions, the phytoplankton biomass is too high to limit mesozooplankton growth and lower the energy transfer efficiency from phytoplankton to mesozooplankton

The important effect of climate factors on spring phenology has been confirmed by numerous studies, but its temporal variation remains unclear. Based on the daily meteorological observation data and annual vegetation phenology data from 1987 to 2016, this study proposes a Time Window Sliding Fitting (TWSF) method. Partial Least Squares (PLS) regression is used to investigate the relationship between

Aquatic macrophytes capture trace elements from water and store them in their tissues, which make them good biomonitors for these substances. But they also capture suspended particulate matter that could bias the concentration measurements in the moss tissues. To avoid this problem, many biomonitoring studies using mosses include a washing step in the sample preparation procedure. However, no data

The use of satellite remote sensing to estimate coloured dissolved organic matter (CDOM) and identify its potential sources is important for monitoring lake water quality and implementing management strategies. In this study, taking Erhai Lake as an example and based on MODIS/Aqua satellite images and in-situ measured data, we used empirical and semi-empirical methods to develop algorithms for CDOM

(2020) and the time-varying difference-in-differences (DID) model is used to examine the role of forest city construction (FCC) in reducing carbon emissions. The results show that the FCC reduced CO2 by 1.71%

Grassland degradation is one of the most pressing challenges in natural environment and anthropogenic society. However, there is yet no effective approach for monitoring the spatio-temporal pattern of large-scale grassland degradation. In particular, the research on grassland changes in the harsh natural environment such as the Qinghai-Tibet Plateau is still in its infancy due to complexity, and it

Nitrous oxide (N2O) is one of the most important greenhouse gases and has the potential to aggravate global warming. Arbuscular mycorrhizal (AM) fungi form mutualistic associations with most terrestrial plants, which can help plant nitrogen (N) uptake and have also been shown to reduce soil N2O emissions. However, the development and species community composition of AM fungi are influenced by warming

Soil moisture is connected to atmospheric moisture through direct evaporation and vegetation transpiration. This is a complex process that is in focus of numerous hydrological studies. We used the long-term measurements from a typical farming-pastoral ecotone in northern Hebei Province of China to study the relationship between the daytime and nighttime fluctuations of grassland surface soil moisture

Desertification can pose threats to global socioeconomic development, ecological and environmental safety, human health and survival.

A field experiment was performed along a desertification gradient in an alpine steppe, the Northern Tibet

The Grain to Green Program (GTGP) has directly led to large-scale transformational land use/cover changes and has impacted ecosystem services. Therefore, it is of great importance to determine the relationship between the land use change and ecosystem services in retired farmland areas. Based on multi-temporal land use data (1980, 1990, 1995, 2000, 2005, 2010, 2015, and 2018), the benefit transfer

Rainfall patterns in arid and semi-arid regions are characterized by a reduction in rainfall frequency. However, under this novel climatic condition, potential changes in soil nematode community among different degraded grasslands remain unclear. We conducted a mesocosm experiment to test the effects of lower precipitation frequency (decreased by 50% from the long-term mean) on nematodes in the lightly

The Jinghe County of the Ebinur Lake Basin was chosen as the study area. Based on Landsat TM / OLI images obtained in 2007 and 2017, this paper attempts to use CLUE-S model to predict LUCC under three different scenarios (Natural Development scenario, Farmland Protection scenario, Water Resources Protection scenarios) in 2027. Landscape indices and ecological risk index were calculated and spatially

Biofloc technology (BFT) has been called an environmentally friendly aquaculture approach.

Submerged macrophytes-biofilm symbionts are sensitive to water pollution and can be possibly used as the bio-indicators of aquatic ecosystems. However, the physiological responses of submersed macrophyte and microbial community to environmental pollution remain unclear. In this study, impacts of three kinds of treated or without treated sewage (JP, EP and CP) on Vallisnerian natans and microbial community

According to the European Water Framework Directive (WFD), restoration actions are needed if the present-day ecological quality status (EcoQS) is worse than good. However, less stringent environmental objectives may be allowed if the water body’s natural condition is such that it may be unfeasible or unreasonably expensive to achieve good conditions. In the Inner Skjolda- and Grindefjord, an isolated

The emerging concept of plant community traits offers a promising tool for explaining the variations in forest productivity. We measured the leaf thickness (LT), leaf area (LA), specific leaf area (SLA), and leaf dry matter content (LDMC) of 234 plant species from seven adjacent Korean pine and broad-leaved mixed forests in Northeast China, which varied in restoration time after selective logging (6

Urbanization demands finer coordinated development of the urban human-earth relationship with high quality. Although a large number of studies have explored the long-term and large-scale coupling effect of urbanization and eco-environment, there is a lack of finer spatiotemporal method and assessment. Therefore, this paper proposes a monthly-scale pixel-based coupling coordination degree (CCD) model

In palaeolimnology, microfossils play an important role as ecological indicators of lake history. A reliable interpretation of microfossil data requires a comprehensive understanding of transport processes as well as determining whether microfossil assemblages are representative of their living communities. The occurrence of transport in ostracod taphocoenoses can be identified from the population

The inundation state is one of the main factors affecting the development of river floodplain wetlands, and the water inundate frequency (WIF) is a commonly used characterisation tool.
