Because of this, it is essential to know their demographic characteristics. We systematically reviewed the publications with matrix population models (MPM) and integral projection models (IPM) in indexed journals, databases like the COMPADRE Plant Matrix Database and grey literature. In each publication, we recorded the literature characteristics, the population attributes, and the methods and metrics applied to describe them. We reviewed studies published until April 2022. We found 83 publications applied demographic modeling, 43 of which were of grey literature. Most studies were conducted in North America and on the tribe Cacteae, with a scarce representation of South American cactus. Compared to a previous review from 20 years ago, our study recorded a 488% increase in the number of publications and a 33.3% increase in the COMPADRE demographic database. We found demographic data for 65 taxa and very few studies covered a medium-to long-term period. MPMs were the most used until the 2009 when IPMs began to gain popularity. Population growth rates were commonly close to the unit (<strong><em>λ</em></strong> ≈ 1), but we identified a wide range of <strong><em>λ</em></strong> values. Species position in the demographic triangle showed that the populations in the tribes Echinocereae, Cereeae and Cylindropuntieae were located towards the end of the survival axis, while those in the tribes Cacteae, and Opuntieae had a more variable location. Applications of demographic models have focused on the analysis of life history traits (growth and turnover) and employing numerical simulations to simulate the consequences of variations in vital rates on <strong><em>λ</em></strong>. Interactions with the climate and the nurse-protected system are analyzed frequently. Nonetheless, a limited number of research explores the socioeconomic and political components of management and conservation. Finally, even though Cactaceae is the plant group with the most extensive demographic research, models are available for only 3.5% of the species.</p></div>","PeriodicalId":51080,"journal":{"name":"Journal of Arid Environments","volume":"224 ","pages":"Article 105226"},"PeriodicalIF":2.6,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S014019632400106X/pdfft?md5=532f4989548bd43710bbf1616fbcaa33&pid=1-s2.0-S014019632400106X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141638786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Only birds triggered the flower-opening mechanism and carried pollen, whereas insects behaved as nectar thieves. The addition of nectar seemed to increase fruit formation compared to control flowers, whereas nectar removal tended to decrease fruit set. The natural low fruiting levels could be the result of a combination of factors such as low legitimate pollinator visitation rate, low-diverse and poor-quality pollen receipt due to geitonogamy promoted by the great floral display and the abundant floral reward, intense levels of nectar theft by native insects, and even climatic stress. The reduced size of populations and low fitness settles the grounds for potentially low genetic diversity, inbreeding depression and, ultimately, demographic declines.</p></div>","PeriodicalId":51080,"journal":{"name":"Journal of Arid Environments","volume":"224 ","pages":"Article 105224"},"PeriodicalIF":2.6,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141623063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates meteorological droughts and their assessment through drought indices. We compared the suitability of satellite precipitation data from GPM-IMERG and TRMM with ground-based observations from 17 locations. To assess the severity and to identify the best index for the spatiotemporal analysis of the drought we employed two indices: the Standard Precipitation Index (SPI) and a new satellite-based index the Drought Exceedance Probability Index (DEPI). A thorough analysis of the dry periods identified by DEPI was carried out and later compared with two established metrics for analyzing rainfall patterns: the persistence of monthly rainfall and the correlation of monthly rainfall patterns with one-month auto lag. Evaluation and robust statistical analysis (R, r, RMSE & RSR) were performed for quantitative measure of drought indices performances. Additionally, an assessment of the regularity of drought episodes recorded using the DEPI and SPI reveals a considerable difference in terms of regular dry and mild wet occurrences. Following IMERG-GPM and gauge data comparison analysis between DEPI and SPI, DEPI offered superior agreement with gauge data. The outcomes of this analysis offer valuable insights for selecting the best satellite product for spatiotemporal drought analysis.","PeriodicalId":51080,"journal":{"name":"Journal of Arid Environments","volume":"18 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141770512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, few studies have explored such operating mechanisms across multitrophic levels and ecosystem functions, such as pollination. In this large grassland biodiversity study in Inner Mongolia, we partitioned the net biodiversity effect on seed production into the complementarity and selection effects and related these effects to functional diversity and the composition of flowering plant traits, and a range of plant–pollinator network parameters. The positive effect of plant species richness on the complementarity effects overwhelmed the negative effect on the selection effects. Hence, plant diversity positively impacted the net biodiversity effects. In addition, the net biodiversity and complementarity effects were increased in plant communities dominated by species with long inflorescences, suggesting that the facilitative effects of these dominant species attract more pollinators for other species. Furthermore, the complementarity effect increased with decreasing niche overlap of pollinator species, indicating complementary resource use among plant–pollinator interactions.
