Daily mean precipitation was obtained from a meteorological station. We analysed the effect of rainfall and colony features on gemmae production at the shoot and cm2 levels using generalized linear models. \u0000Results: C. afzelii produced gemmae more constantly than S. incompletus. Gemma production is higher during months of high rainfall. The rainfall and number of gemmiferous shoots are suitable predictors of gemma production. \u0000Conclusions: Our results exemplify how rainfall and gemmiferous shoots influence the production of asexual propagules in two mosses with different reproductive strategies in the same tropical environment. This information is essential to understand the population dynamics of tropical mosses.","PeriodicalId":54375,"journal":{"name":"Botanical Sciences","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49177637","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}

Calotropis procera show germination traits that may increase their probability of colonization. \u0000Studied species: Calotropis procera is a perennial plant native to some desertic areas in Asia and Africa and now naturalized in America. \u0000Study site and dates: Mature fruits were collected in Oaxaca in September 2019 to test germination parameters. The last experiment was conducted in September 2021. \u0000Methods: We determined the effect of different temperatures, photoblastic response, and loss of viability of seeds kept at laboratory conditions for two years. We performed several sowings under controlled conditions and achieved germinability, t50 and the time to germinate. \u0000Results: Seeds were non-dormant, neutral photoblastic and did not lose viability after two years of dry storage. Temperature affected germinability and t50. Optimum germination temperature was 30 °C with no germination above 40 °C. \u0000Conclusions: Germination requirements of seeds of Calotropis procera studied were similar to those reported worldwide. Though seed germination was affected by maximum mean temperatures, seeds germinated fast and at high percentages under a wide range of temperatures, which together with other attributes, may confer C. procera great chances for successful colonization.","PeriodicalId":54375,"journal":{"name":"Botanical Sciences","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41921204","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}

However, there are still few scientific reviews that have discussed the relevance of practical applications in current palynology and its perspectives as a theoretical framework for the study of integrated landscape management. This review shows palynological contributions within agricultural model diversities in both natural and novel ecosystems.

What are the approaches of pollen analysis on landscape management and biodiversity conservation?Studied species: Pollen analysis and palynomorphs.Study site and dates: Global literature from current palynology.Methods: Global scientific literature using keywords, theoretical frameworks, and original articles.Results: We identified palynological perspectives for the study of sustainability based on global scientific literature: 1) ecological-evolutionary and 2) interdisciplinary research. In addition, we discussed some synergies and trade-offs between ecosystem services that were recognized through current palynology in different farming landscapes: biodiversity-based farming systems and chemical input-based farming systems. While pollen morphology and descriptive palynology can provide the basis for crop improvement, biological invasions, and the effect of deforestation on native species, more analytical approaches such as land-use indicators are necessary for sustainable management. In addition, we have included some biocultural aspects to conservation, due to a lack of practical discourse in current palynology.
