Karst collapse is one of main important geological disasters in Linyi city of Shandong Province. In this article, risk assessment of present and forecast situation of karst collapse have been done by the method of fuzzy comprehensive evaluation based on level analysis at the first time. The hazardous assessment, the vulnerability and the expected loss have been assessed, and then the risk assessment map of karst collapse at present is obtained and prevention and control work of karst collapse is expected to develop. It puts up availability exploration on prevention of the same geohazards, and provides a reference pattern. © Published under licence by IOP Publishing Ltd.

Restoration of degraded drylands is urgently needed to mitigate climate change, reverse desertification and secure livelihoods for the two billion people who live in these areas. Bold global targets have been set for dryland restoration to restore millions of hectares of degraded land. These targets have been questioned as overly ambitious, but without a global evaluation of successes and failures it is impossible to gauge feasibility. Here we examine restoration seeding outcomes across 174 sites on six continents, encompassing 594,065 observations of 671 plant species. Our findings suggest reasons for optimism. Seeding had a positive impact on species presence: in almost a third of all treatments, 100% of species seeded were growing at first monitoring. However, dryland restoration is risky: 17% of projects failed, with no establishment of any seeded species, and consistent declines were found in seeded species as projects matured. Across projects, higher seeding rates and larger seed sizes resulted in a greater probability of recruitment, with further influences on species success including site aridity, taxonomic identity and species life form. Our findings suggest that investigations examining these predictive factors will yield more effective and informed restoration decision-making.

Nitrogen circulation and transformation on water-sediment interface of Source Water Reservoir was studied through comparative experiment between sterilization incubation and non-sterilization incubation. The results showed that NH4 +-N concentration in non-sterilization group continually increased and NO3 - decreased by 97.7%. In the sterilization group, there was no obvious change except the increase caused by diffusion. The S2- produced by sulfate reducing bacteria (SRB) weakened the denitrification. The content of TN and organic matter in the non-sterilization sediment samples decreased 26.28% and 18.37% respectively. After incubation, the quantity of ammonifiers, denitrifying bacteria and SRB increased greatly in the sediment of nonsterilization group. Therefore it can be concluded that microbes accelerated nitrogen circulation and conversion on water-sediment interface. Anaerobic condition is an important factor for NH4 +-N release. SRB can inhibit denitrification, thus slow down the nitrogen removal rate of sediment. Copyright © 2016, AIDIC Servizi S.r.l.

The recent Kunming-Montreal Global Biodiversity Framework (GBF) sets ambitious goals but no clear pathway for how zero loss of important biodiversity areas and halting human-induced extinction of threatened species will be achieved. We assembled a multi-taxa tracking dataset (11 million geopositions from 15,845 tracked individuals across 121 species) to provide a global assessment of space use of highly mobile marine megafauna, showing that 63% of the area that they cover is used 80% of the time as important migratory corridors or residence areas. The GBF 30% threshold (Target 3) will be insufficient for marine megafauna's effective conservation, leaving important areas exposed to major anthropogenic threats. Coupling area protection with mitigation strategies (e.g., fishing regulation, wildlife-traffic separation) will be essential to reach international goals and conserve biodiversity.

Unraveling the mechanisms underlying the maintenance of species diversity is a central pursuit in ecology. It has been hypothesized that ectomycorrhizal (EcM) in contrast to arbuscular mycorrhizal fungi can reduce tree species diversity in local communities, which remains to be tested at the global scale. To address this gap, we analyzed global forest inventory data and revealed that the relationship between tree species richness and EcM tree proportion varied along environmental gradients. Specifically, the relationship is more negative at low latitudes and in moist conditions but is unimodal at high latitudes and in arid conditions. The negative association of EcM tree proportion on species diversity at low latitudes and in humid conditions is likely due to more negative plant-soil microbial interactions in these regions. These findings extend our knowledge on the mechanisms shaping global patterns in plant species diversity from a belowground view.

Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R package (BioTIMEr) to facilitate use of the database. Main Types of Variables Included The database is composed of one main data table containing the abundance records and 11 metadata tables. The data are organised in a hierarchy of scales where 11,989,233 records are nested in 1,603,067 sample events, from 553,253 sampling locations, which are nested in 708 studies. A study is defined as a sampling methodology applied to an assemblage for a minimum of 2 years. Spatial Location and Grain Sampling locations in BioTIME are distributed across the planet, including marine, terrestrial and freshwater realms. Spatial grain size and extent vary across studies depending on sampling methodology. We recommend gridding of sampling locations into areas of consistent size. Time Period and Grain The earliest time series in BioTIME start in 1874, and the most recent records are from 2023. Temporal grain and duration vary across studies. We recommend doing sample-level rarefaction to ensure consistent sampling effort through time before calculating any diversity metric. Major Taxa and Level of Measurement The database includes any eukaryotic taxa, with a combined total of 56,400 taxa. Software Format csv and. SQL.

Pollution characteristics of thermally-stratified reservoir: A case study of the Heihe reservoir in Xi’an city, China

引用

Journal of Chemical and Pharmaceutical Research 2014年第7期6卷 1231-1240页

作者： Chai, Beibei Li, Yajiao Huang, Tinglin Huang, Tinglin School of Architecture and Civil Engineering Xi’an University of Science and Technology Xi’an China Geological Resources and Geological Engineering Postdoctoral Research Station Xi’an University of Science and Technology Xi’an China School of Environmental and Municipal Engineering Xi’an University of Architecture and Technology Xi’an China Key Laboratory of Northwest Water Resource Environment and Ecology MOE Xi’an China

Reservoirs are important water sources for most large cities. Many problems are attributed to their thermal stratification and inherent pollution characteristics. So the pollution characteristics of a typical thermally-stratified reservoir in Xi’an City, China were studied by field investigation and laboratory simulation. The results showed that: (1) The Heihe Reservoir was stably thermally stratified, particularly during summer months and that the deeper the water layer, the lower the oxygen concentration. Thus, the bottom layer became completely devoid of oxygen. (2) The water quality problems of this reservoir were mainly caused by internal pollutant release from the sediments. (3) The simulation experiment in the laboratory proved that the pollutants in the Heihe Reservoir sediment could be easily released into the overlying water. (4) The stratification broke up at seasonal changes. Hence, the pollutants released from the sediment transported to the upper layer as the layer became mixed. The pollutants supplied algae with sufficient nutriment, and harmful algae bloomed accordingly, especially in summer. Thus to destroy the stratification, aerate the bottom layer would be effective method to solve the water quality problems for thermally-stratified reservoir. © 2014, Journal of Chemical and Pharmaceutical Research.
