Future climate scenarios predict changes in rainfall regimes. These changes are expected to affect plants via effects on the expression of root traits associated with water and nutrient uptake. Associated microorganisms may also respond to these new precipitation regimes, either directly in response to changes in the soil environment or indirectly in response to altered root trait expression. We characterised arbuscular mycorrhizal (AM) fungal communities in an Australian grassland exposed to experimentally altered rainfall regimes. We used Illumina sequencing to assess the responses of AM fungal communities associated with four plant species sampled in different watering treatments and evaluated the extent to which shifts were associated with changes in root traits. We observed that altered rainfall regimes affected the composition but not the richness of the AM fungal communities, and we found distinctive communities in the increased rainfall treatment. We found no evidence of altered rainfall regime effects via changes in host physiology because none of the studied traits were affected by changes in rainfall. However, specific root length was observed to correlate with AM fungal richness, while concentrations of phosphorus and calcium in root tissue and the proportion of root length allocated to fine roots were correlated to community composition. Our study provides evidence that climate change and its effects on rainfall may influence AM fungal community assembly, as do plant traits related to plant nutrition and water uptake. We did not find evidence that host responses to altered rainfall drive AM fungal community assembly in this grassland ecosystem.

Background and Study Aim: The main purpose behind the study was to establish the challenges in relation to the acquisition of life skills among university student-athletes of Khyber Pakhtunkhwa. The study assessed the extent to which the concern existing resources, facilitators, and trainer attitude influences life skills acquisition among student-athletes. Material and Methods: Descriptive survey research design was followed to obtain desirable results. The target population of this study consisted of all those who participated in different sport at the university level of Khyber Pakhtunkhwa (KP), Pakistan. Amongst them, we selected a representative sample (n=389 fifty 50% of the total population) with the help of a simple random sampling technique. The Statistical Package for Social Sciences (SPSS) version, 24 was used to code and analyse the data. The hypotheses were tested by applying statistical tests like Step-wise regression and independents sample t-test. The significance level of 0.05 was fixed to accept or reject the set hypotheses. Results: Findings of the study indicated that existing resources, facilitators, and trainer/coach attitude significantly influences life skills acquisition among student-athletes (.001, .001 & .000 < .05). The analysed data revealed no significantly difference regarding extent to which specific challenges such as existing resources, facilitators, and trainer attitude influences the acquisition of life skills (.500, .133 & .149 > .05). Conclusions: The findings of the study revealed that all participants have agreed upon the importance of life skills. Therefore, the life skills course might be considered as an integral part of every educational curriculum of Pakistan. It is suggested that a minimum of 2 hours per week may be included in the educational curriculum of each discipline.
