It is necessary to explore the effects of environmental factors on the distribution of pests and provide implications for pest management in alpine landscapes. The main objective of this study was to explore whether habitat heterogeneity and topographic variation could drive insect pest distributions in alpine landscapes. We used species distribution modelling to project the distributions of 58 insect pest species in alpine landscapes based on occurrence records from 5513 field sites and different sets of environmental variables (i.e., climate, climate + habitat heterogeneity, climate + topographic variation, and climate + habitat heterogeneity + topographic variation). Then, we applied the jackknife method to determine the contribution of environmental variables to insect pest distributions. We found that habitat heterogeneity and topographic variation could significantly affect the distribution probability for all insect pest species in Qinghai, China. The response curves of the probability of pest distribution to habitat heterogeneity and topographic variation vary depending on the species present in alpine landscapes. There were four types of response curves of habitat heterogeneity and topographic variation to insect pest distribution probability, namely, 1) increasing, 2) decreasing, 3) increasing and then decreasing, and 4) decreasing and then increasing. Habitat heterogeneity and topographic variation should be integrated into modelling the distributions of insect pest species in alpine landscapes for pest risk assessment.</span></span></p></div>","PeriodicalId":7048,"journal":{"name":"Acta Ecologica Sinica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49728117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The overall density was recorded in the range from 411 trees ha</span>⁻¹ to 840 trees ha⁻¹, whereas the TBC values existed between 21.72 m² ha⁻¹ to 95.41 m² ha⁻¹.

Overall, this study reviews enough evidences of species susceptibility towards fragmentation of habitats because of anthropogenic disturbance. Moreover, the current species range distribution records will help to develop baseline datasets for existing tree species to access in future for their range shift from the conventional habitats due to climate change and notify them as climate sensitive species in Himalaya.</p></div>","PeriodicalId":7048,"journal":{"name":"Acta Ecologica Sinica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49712702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to present seasonal thermal performances of single slope solar still developed by using rectangular channels filled with heat storage material. Thus, a parametric study of the developed passive solar still was numerically formulated using a finite element method carried out by COMSOL Multiphysics to predict the effect of design parameters: number and width of rectangular channels. Hence, the optimum values were tested at various seasons to define the increasing rate of daily yield. In fact, for selected typical days, it was deduced from the simulation results that the optimal design for modified solar still with rectangular channels is suggested with 5 numbers and 2 cm width for best output productivity. Also, the analysis of MSSRC during autumn, winter, spring, and summer shows that the daily yield is 24.40%, 37.79%, 9.80%, and 22.66% greater than the conventional solar still respectively.</span></span></p></div>","PeriodicalId":7048,"journal":{"name":"Acta Ecologica Sinica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49713100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
