Article Synopsis
  • Desertification is a significant global issue causing the destruction of ecosystems, with the impact of soil microorganisms during restoration efforts not well understood.
  • A study in the Hulun Buir Sandy Land of Northeast China showed that restoring desertified areas led to increased plant diversity and improved soil properties, including a decrease in soil pH and increases in organic and nitrogen content.
  • While bacterial diversity increased in restored areas, fungal diversity decreased, and certain bacterial groups became more prevalent, highlighting the complex interactions between soil microorganisms and environmental factors during ecosystem restoration.

The purpose of this study was to determine the (a) dose-response effects of cognitively engaging movement games (CEMGs) designed to improve aerobic capacity, interference control (IC), and academic performance, (b) relationship between intervention-induced improvements in aerobic capacity, IC, and academic performance, and (c) moderation effect of IC on the relationship between aerobic capacity and academic performance in overweight children. Seventy-five overweight children (aged 11.23 ± 0.

Soil microbes play key roles in ecosystem functions, especially in the recovery of ecosystems from disturbance, and exploring community assembly under changing environments has long been a central theme in microbial ecology. The response of abundant and rare bacteria in desertified land to restoration is still unclear. Here, we investigated the effects of vegetation restoration on the assemblage patterns of abundant and rare bacteria in soil across the four sandy lands (Hulunbeir, Horqin, Otindag, and Mu Us) in northern China.

Objectives: Self-description research on athletes with intellectual disabilities (ID) is under investigated. The specific aims in this paper are (a) to identify the differences in physical self-concept and body image by Unified Sports experiences, and (b) to investigate predictors of physical self-concept.

Methods: Participants included 89 Special Olympics athletes who had Unified Sports experiences (USE,  = 43) and those without USE ( = 46).

Background: Little research has looked at the associations between sex, weight status and culture, and the physical self-perceptions and body dissatisfaction of individuals with intellectual disabilities (ID) involved in Special Olympics (SO) sports.

Aims: To examine sex- (male vs female), weight status- (non-overweight/obese vs. overweight/obese), and culture-based (North American vs.

Ground-dwelling arthropod communities are influenced by numerous biotic and abiotic factors. Little is known, however, about the relative importance of vegetation structure and abiotic environmental factors on the patterns of ground-dwelling arthropod community across a wide range of soil salinities. Here, a field survey was conducted to assess the driving forces controlling ground-dwelling arthropod community in the salinized grasslands in the Hexi Corridor, Gansu Province, China.

Evaluations of restoration success usually focus on the structural aspects of ecosystems. Pollination, as an important functional aspect, is often overlooked. Here, the shifts in pollinator assemblage and pollen limitation in the desert shrub Caragana microphylla were examined along a restoration gradient in Horqin Sand Land, northern China.

In animal pollinated plants, phenological shifts caused by climate change may have important ecological consequences. However, no empirical evidence exists at present on the consequences that flowering phenology shifts have on the strength of pollen limitation under experimental warming. Here, we investigated the effects of experimental warming on flowering phenology, flower density, reproductive success, and pollen limitation intensity in Caragana microphylla and evaluated whether earlier flowering phenology affected plant reproduction and the level of pollen limitation using warmed and unwarmed open top chambers in the Horqin Sandy Land of Inner Mongolia, northern China.

Purpose: The study aims to investigate the prevalence and likelihood of overweight and obesity in a large sample of students with intellectual disabilities (ID) from Taiwan.

Method: A secondary analysis of a cross sectional study was employed to examine the body weight status among 7 to 18 year-old students with ID enrolled in public special education schools in 2013. The students were divided into three age groups (7-12 yrs, 13-15 yrs, and 16-18 yrs), four ID levels (mild, moderate, severe, and profound) and six comorbidities of ID (ID only, ID caused by genetic disorders, ID with physical disability, ID with multiple disabilities without physical disabilities, ID with autism spectrum disorders, and others with rare diseases).

Corn seedlings are often harmed by strong wind-sand in the spring in semi-arid wind-sand area of west of Northeast China. In order to understand physiological response mechanisms of the corn seedlings to wind-sand damage, the changes in MDA content, membrane permeability, protective enzymes activities and osmotic regulation substances at 0 (CK) , 6, 9, 12, 15 and 18 m . s-1 wind speed (wind-sand flow strength: 0, 1.

Grassland salinization causes considerable changes to soil and vegetation, which can lead to changes in soil organic carbon (C) and total nitrogen (N). These changes have complex causal relationships. A significant correlation between soil organic C and total N and any soil or vegetation property does not necessarily imply a significant direct effect of the property on soil organic C and total N.

Long-term disturbance of human beings on secondary forest ecosystem would have profound impacts on belowground ecological processes, whereas the community structure and functional diversity of soil fauna would be sensitive to the changes of belowground ecological processes, with significance as an indicator of the changes. In this study, the method of hand-sorting was adopted to investigate the density of soil macrofaunal community in a secondary forest and the Pinus tabulaeformis, Larix kaempferi, Picea abie, and Picea asperata plantations of nearly 30 years old in Xiaolongshan forest area of western Qinling Mountains, and the PCA ordination and one-way ANOVA analysis were applied to analyze the community structure and trophic group composition of soil macrofauna in the five forest types. In the P.
