Scientific work in these fields requires accurate identification of these taxa in the field and recording them using standardized scientific names. However, as journal editors, we frequently encounter manuscripts where authors misunderstand taxonomic nomenclature, leading to errors and making articles challenging for readers to follow. Here, we highlight some practices that we believe should be improved for the benefit of vegetation science and community ecology.&lt;/p&gt;&lt;p&gt;Every year, the editors of &lt;i&gt;Applied Vegetation Science&lt;/i&gt; select one article for the Editors' Award. For the year 2024, the award was bestowed on Lina Lüttgert for the article “Linking trends of habitat types and plant species using repeated habitat mapping data” (Lüttgert et al. &lt;span&gt;2024&lt;/span&gt;). The ongoing changes in habitats and the abundance and distribution of species in landscapes are important research topics (Kapfer et al. &lt;span&gt;2017&lt;/span&gt;; Knollová et al. &lt;span&gt;2024&lt;/span&gt;). However, individual studies focus either on changes in habitat area (e.g., studies based on remote sensing) or on changes in habitat quality, such as the decline of characteristic or threatened species. It is usually assumed that the decline in habitat area correlates with the decline in habitat quality, but is this always the case? Lüttgert et al. (&lt;span&gt;2024&lt;/span&gt;) used data from repeated habitat mapping and data on plant species occurrence from southwestern Germany over the last three decades and compared the changes in habitat area with changes in species occurrence. They found that in some habitats, such as grasslands, the decline in habitat area is correlated with the decline in species characteristic of that habitat. However, this is not always the case. For example, the area of deciduous forests in southwestern Germany increased, but the abundance of the deciduous forest's characteristic species decreased. An important lesson from this study is that conclusions based on the assessment of changes in habitat quantity cannot be interpreted as changes in habitat quality.&lt;/p&gt;&lt;p&gt;There were other articles worthy of consideration. Rivas, Guerrero-Casado, and Navarro-Cerrillo (&lt;span&gt;2024&lt;/span&gt;) also assessed changes in vegetation over the last three decades, but they focused on the fragmentation and functional connectivity of seasonally dry forests in Ecuador. They found that the loss of forest area was 30%, while the loss of connectivity was 75%. Based on their findings, they proposed a new reforestation plan that prioritizes areas where reforestation would improve functional connectivity.&lt;/p&gt;&lt;p&gt;Another interesting paper was the meta-analysis by Berto, Ritchie, and Erickson (&lt;span&gt;2024&lt;/span&gt;), which looked at the effects of seed enhancement technologies such as acid treatment, coating, pelleting, flash flaming and priming on germination, emergence, shoot ","PeriodicalId":55494,"journal":{"name":"Applied Vegetation Science","volume":"28 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/avsc.70009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143111424","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}

We aimed to identify by a meta-analysis the best option for biodiversity in extensively managed grassland in Europe.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Materials and Methods</h3>\u0000 \u0000 <p>Scopus and Web of Science were systematically searched for publications that appeared before 31 January 2024 and that reported the effects of management schemes on biodiversity patterns of extensively managed grassland. Out of 971 original records, 54 full-text articles were included in the final analysis. We extracted values for mean, SD and sample size of species numbers and calculated Hedge's <i>g</i> to rate treatment effects.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Extensive management (grazing, mowing) increased species number compared to abandonment (effect size: Hedge's <i>g</i> = 1.30). For plant diversity, extensive management had a strong positive effect (<i>g</i> = 1.78), while the effect of grazing and mowing was minor for animal biodiversity (<i>g</i> = 0.03). The results were recognizably influenced by the investigated plot sizes. Small plots (&lt;10 m²) showed a much stronger effect (<i>g</i> = 2.19) than larger plots (<i>g</i> = 0.56). The type of extensive management, grazing or mowing, had no influence on the results.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>In line with results on grasslands in general, our results underline that biodiversity of extensively managed grasslands benefits from extensive grazing or mowing. Although abandonment had a negligible effect on animal species richness, the effect on vegetation was strong. The low effect of abandonment on the fauna can be explained by the relatively short duration of the studies. The characteristics of grassland were still present, and it had not turned into forest. Extensive grazing or mowing are therefore the best options for grassland managed for conservation purposes.</p>\u0000 </section>\u0000 </div>","PeriodicalId":55494,"journal":{"name":"Applied Vegetation Science","volume":"27 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/avsc.70003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642099","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}

It presents a comprehensive classification of the region's grasslands, including tall tussock grasslands, humid grasslands, stony grasslands, and grasslands with scattered shrubs and trees. Each recognized unit is distinguished by diagnostic species and a distinct floristic composition. Our findings emphasize a significant division between grasslands at higher elevation, abundant in Andean species, and Piedmont and shrubby grasslands at lower elevations, characterized by a higher prevalence of Chacoan and other Neotropical species. Grassland vegetation in other regions of the Sierras Pampeanas remains poorly studied, requiring additional research to determine the syntaxonomic position of this vegetation.</p>\u0000 </section>\u0000 </div>","PeriodicalId":55494,"journal":{"name":"Applied Vegetation Science","volume":"27 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642170","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}
