It occurs pantropically, with highest diversity in the Neotropics. Species are epiphytic, lithophytic, or terrestrial, as well as geophytic in diverse vegetation types, where specifically endemic taxa with limited distribution ranges are threatened by land-use changes. Many of the 134 <em>Peperomia</em> species recorded are distributed in tropical lowland and humid montane forests in southern Mexico, where natural vegetation has been converted into agricultural and livestock fields. Considering the lack of knowledge about the distribution patterns and conservation status of this genus in Mexico, this research aims to determine the geographic distribution and anthropogenic threats to endemic <em>Peperomia</em> species through an exhaustive review and compilation of their occurrence records, followed by a preliminary conservation assessment using the ConR package based on the IUCN criterion B. We determined that a total of 43 <em>Peperomia</em> species are endemic to Mexico, most of which occur in the Sierra Madre del Sur and Veracruzana biogeographic provinces in tropical rain, oak, and coniferous forests. According to the criteria of the IUCN Red List, more than 80 % of these belong to a threatened category, showing that independently of their growth habits most species were Endangered (EN). This is because the ecoregions with warm-humid and temperate forests that keep their highest richness are also among the habitats most affected by human activities. As many of these threatened species have few records, more fieldwork in little explored regions is needed to gather and digitize additional herbarium specimens with reliable identification, which are an essential information source for conservation studies.</div></div>","PeriodicalId":55156,"journal":{"name":"Flora","volume":"337 ","pages":"Article 152933"},"PeriodicalIF":1.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146102917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a slope restoration experiment in Yajiang County, Sichuan Province, China to identify an effective seeding density for shrubs and explore the effect of a grass–shrub combination on slope stabilization. Root morphology and tensile strength were assessed to achieve these objectives. Four treatments using the seeds of grass (<em>Festuca elata</em> Keng ex E. B.

Results showed that from M1 to M4, the first order lateral root length of shrubs decreased by 20.92%, the second order lateral root length by 31.53%, root biomass by 8.10%, total root length by 29.74%, and specific root length by 23.30%. Moreover, from M1 to M4, the tensile strength of second order lateral roots decreased by 25%, root cellulose content decreased by 18%, hemicellulose content increased by 8%, and lignin content increased by 22%. Root tensile strength was positively correlated with cellulose content and negatively correlated with lignin content. These findings demonstrated that the root morphology and tensile strength of shrubs were significantly influenced by seeding density. Under high-density conditions, shrubs adopted a conservative survival strategy. A low seeding density combined with a grass–shrub configuration better promotes shrub root development, enhances tensile strength, and facilitates surface erosion control in the early stages, thereby representing a more effective approach for slope stabilization.</div></div>","PeriodicalId":55156,"journal":{"name":"Flora","volume":"337 ","pages":"Article 152941"},"PeriodicalIF":1.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146174855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
