With proper planning and ongoing maintenance and monitoring, these corridors have the potential to be transformed into native meadow, offering vital pathways connecting natural heritage systems and supporting wildlife movement, while promoting biodiversity, natural functions, and ecosystem health. In 2019, seeding trials were established in the Gatineau Hydro Corridor in east Toronto where a long-term meadow creation project (The Meadoway) is ongoing, to evaluate the effectiveness of herbicide treatment (glyphosate), sowing method, and sowing season on seeding success with the goal of informing site-specific meadow creation techniques. Seed mixes included a variety of native grasses and forbs and were dominated by copper savannah grass (Sorghastrum nutans), big bluestem (Andropogon gerardii), little bluestem (Schizachyrium scoparium), and switch grass (Panicum virgatum). Overall, fall or winter seeding with herbicide led to the highest seeding success. There was no difference in the effectiveness of hand seeding or using the seed drill. The results of this work provide valuable insights into effective seeding techniques to improve seeding success and also highlight the benefits of in situ experimentation to inform meadow creation techniques.","PeriodicalId":9092,"journal":{"name":"Botany","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141948270","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}

Understanding factors influencing tree regeneration is crucial for reforestation efforts in grazed areas. Given the limited understanding of Parlatore's Podocarp (Podocarpus parlatorei Pilg.) regeneration ecology, a unique gymnosperm species in the Southern Yungas' Montane Forest, we evaluated the growth and survival of its saplings for one year after planting them both inside and outside an exclosure, and in association with or without unpalatable nurse plants. Inside the exclosure, sapling survival was 100%, regardless of nurse plants. However, outside the exclosure saplings associated with nurse plants had 19.5 times higher survival probability. Growth rates were higher inside the exclosure and for saplings associated with nurse plants. The positive effect of nurse plants on growth was similar inside and outside the exclosure. Cattle browsing and trampling on Parlatore's Podocarp were observed for the first time, highlighting a previously undocumented threat to the species. Our findings offer valuable insights for ecological restoration, potentially suggesting strategic sapling planting near unpalatable plants and considering cattle exclusion in key areas to enhance long-term restoration success in the Southern Yungas' Montane Forest.","PeriodicalId":9092,"journal":{"name":"Botany","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141820871","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}

This method's effectiveness in Mediterranean climates, which face unique challenges like urban heat islands and biodiversity loss, is underexplored in literature and practice. We are leading a project in Italy to identify optimal plant assemblages, addressing the method's documentation gap in urban settings. It explores the potential of Tiny Forests to provide ecosystem services and improve urban liveability against climatic extremes.

The spatial-structure genetics of Pinus leiophylla Schiede ex Schltdl. & Cham. was investigated in adults and seedlings of remnant populations from central Mexico. Two chloroplast intergenic regions were sequenced of two cohorts (adults and seedlings) of 121 individuals of P. leiophylla from three localities. Higher genetic differentiation was found in adults (ФST = 0.09) than in seedlings (ФST = 0.03). The discriminant analysis of principal components detected four genetic clusters and the Mantel test found a weak but significant isolation by distance pattern (r2 = 0.05, p = 0.002). Sixteen percent of genetic variation was explained by the spatial component according to the genetic neighborhood analysis. And the effect of three landscape features, i.e., elevation, aspect (sine and cosine), and land use, explored with ResistanceGA, detected that land use significantly restricts gene flow between populations, mostly in the farming category. This study emphasizes the critical role of preserving forest cover to maintain connectivity among remnants of P. leiophylla. Insights of this study will contribute to the conservation of conifers in Mexican temperate forests, especially within landscapes heavily altered by human activities.","PeriodicalId":9092,"journal":{"name":"Botany","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141503314","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}

The Sudbury Regreening Recipe included the application of crushed dolomitic limestone, nitrogen–phosphorus–potassium fertilizers, grass–legume seed mixtures across 8200 ha, and subsequent tree planting across 25 000 ha of acidic metal-contaminated land. The current study evaluated shifts in understory vegetation diversity and soil geochemistry on a chronosequence of sites treated the same way between 1982 and 2012. Fifty-six plant species were identified across the 24 sites, only four of which were planted in the initial remediation effort. Key factors influencing plant community composition and diversity were related to shifts in soil properties over time: bulk density, LFH layer depth, and mineral soil horizon pH. Plant communities differed with stand age and rocky sites had significantly different plant communities and lower canopy cover than less rocky sites. Mineral soil horizon pH increased with age, reflecting the movement of applied dolomite in soil. Despite high concentrations of total copper and nickel in soil, plant succession patterns were generally similar to those in naturally recovering forests demonstrating the overall success of the restoration program.","PeriodicalId":9092,"journal":{"name":"Botany","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215474","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}

These cryptic species are uncommon—more so in North America than Scandinavia—and collections are often misidentified. Spore measurements separated Arr. baltica from the others by its narrower spores; average measurements help separate some species a bit better than ranges. So far, Arr. peltigerina was found only in North America, Arr. mohniensis and Arr. talpoides in both Europe and North America, and the remainder only in Europe.

These species have quite uniform vegetative features, making it difficult to differentiate them when they are not in flowering. Here, we examined the leaflets anatomical features of the two species in order to distinguish them while in the vegetative phase. Fully expanded leaves were collected, fixed, embedded in paraffin and cross-sections were made from the leaflets midvein, margin and intercostal region. Ceiba speciosa has hypostomatic leaflets, with continuous biseriate epidermis along the adaxial face, rectilinear margin with a vascular bundle at the end of the margin while Ceiba pubiflora has amphistomatic leaflets, with interrupted biseriate epidermis along the adaxial face and curved margin on the abaxial face. These taxonomically important anatomical features of C. speciosa and C. pubiflora leaflets have provided additional characters good for distinguishing the species especially when they are in the vegetative phase; and therefore updates the existing accounts of the characters useful for the taxonomy of Malvaceae.","PeriodicalId":9092,"journal":{"name":"Botany","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141101203","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}
