It is a prolific pioneer species in freshly exposed soil in landslide areas of the western Himalayas and has the potential of fixing nitrogen. A study was conducted to assess the reproductive phenology, pollen production, pollen release, and pollen-mediated gene flow of Alnus nepalensis by considering a patch of trees as a pollen source in the temperate forest of Garhwal Himalaya to develop sustainable management strategies relating to the plantation geometry in seed orchards. Staminate flowers of A. nepalensis are composed of “cymules”. The presence of bifid stigma and protandry condition were the unique features of the species. Flowering in the male phase was initiated in the last week of September and continued till November. Peak shedding of pollen generally proceeds peak receptivity by 1–2 weeks. The time between onset and peak flowering was 2 weeks 4 days and the total average duration of the flowering period was about 24.8 days. Temperature and relative humidity played a major role in pollen release and the maximum pollen release occurred at 29.2 °C at 13.00 hrs of the day. Pollen production per catkin varied significantly among trees. The average pollen grains per tree were 2.20 × 1010. The pollen-ovule ratio suggests that the breeding system of A. nepalensis falls under the class xenogamy. Pollen mediated gene flow revealed that the significant pollen which can cause pollination of A. nepalensis can travel up to 40 m uphill and 80 m in downhill directions. Thus, an isolation strip of 80 m is sufficient to manage the seed orchard of A. nepalensis in the western Himalayan region.","PeriodicalId":52505,"journal":{"name":"Folia Oecologica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41811130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, digital biodiversity repositories such as the Global Biodiversity Information Facility (GBIF) has been promoted for its central role in gathering and harmonizing biodiversity data worldwide, thereby facilitating these assessments and monitoring efforts. While GBIF data has been investigated for its potential at a large scale and in natural ecosystems, the question remains as to what extent, and in which context, is GBIF data applicable to urban biodiversity assessment and monitoring? In this study, we assessed the spatial patterns of biodiversity, by exploring species richness patterns in relation to land use types for three taxonomic groups (birds, mammals and arthropods) in three cities in The Netherlands (Rotterdam, Amsterdam and Groningen) at multiple spatial scales. We found significant variation in the effect of land uses on the species richness patterns, in terms of taxonomic group, spatial configuration and land cover type, and across spatial scales. Our study demonstrates the potential of GBIF data while highlighting the importance of the careful selection of one or multiple spatial scales, especially in relation to the taxonomic group characteristics and ecology and the spatial configuration of the cities studied.","PeriodicalId":52505,"journal":{"name":"Folia Oecologica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43186774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is especially true in areas where the topography is complex and forests are vulnerable to human activity. In this study, a set of topographic, soil, and climatic variables were used to determine their effects on the composition and diversity patterns of two forests in the West Usambara Mountains (Tanzania). Two-phase systematic sampling was used to collect vegetation data from 159 sample plots distributed across the forests. An agglomerative hierarchical clustering method was used for forest community classification, and indicator species analysis was used to determine the species significantly associated with forest communities. The influence of environmental variables on forest communities was analysed using canonical correspondence analysis (CCA). Finally, we evaluated diversity patterns by comparing diversity indices (Shannon-Wiener diversity index, evenness, and richness) and beta diversity processes. In total, 7,767 individual trees belonged to 183 species, 132 genera, and 66 families were quantified. We found that (i) the forests of West Usambara can be divided into three different forest communities; (ii) each forest community has a specific set of topographical, soil, and climate variables; (iii) there are significant differences in Shannon diversity and richness indices among communities; and (iv) community composition is mostly influenced by species turnover than by species nestedness. Our study revealed the importance of considering a set of environmental variables related to climate, soil, and topography to understand the variation in the composition and diversity of forest communities in tropical montane forests.","PeriodicalId":52505,"journal":{"name":"Folia Oecologica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47720112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disinfectants were prepared based on sodium hypochlorite (NaOCl). SA contains only NaOCl while earthworm enzymes enrich DoAm. In both commercial products, the NaOCl content did not exceed 5%; pure NaOCl was used as a 10% solution as well. For bioassay, water organisms (Vibrio fischeri, Desmodesmus subspicatus, Daphnia magna and Tubifex tubifex) situated in various trophic levels were used. All the tests were confirmed as suitable for the determination of chlorine’s adverse effects. Because the organisms’ reactions to the tested disinfectants varied, they can be arranged in the following rank order of sensitivity: V. fischeri ≥ D. subspicatus >> D. magna >> T. tubifex. The toxicity of the tested substances (NaOCl, SA, DoAm) depends on the length of exposure, the species of the organism and FAC (free available chlorine) content. The effective concentrations of the tested products ranged from 0.13 to 8.18 μL L–1, i.e., 0.014 to 0.26 mg L–1 of FAC. However, in the tests with T. tubifex and V. fischeri the toxic effect of NaOCl was the weakest; the tests with other two organisms confirmed this compound as the most toxic. Only for T. tubifex (96 hrs) did SA have a more adverse effect than DoAm.","PeriodicalId":52505,"journal":{"name":"Folia Oecologica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42175419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pits were laid along three transects that passed through the most significant relief gradients within the study area. The study of the morphological structure of 20 soil profiles showed that the soil cover is closely related to the geo-morphological structure of the river valley. The morphological characteristics of typical profiles of these soils reflect their structure, properties and genesis and determine the classification position of the soils according to the WRB. Multidimensional scaling allowed us to perform soil ordination in the space of two dimensions. Dimension 1 differentiates soils by the gradient of relief height and/or moisture level. Dimension 2 differentiated hydromorphic soils. The properties of Quaternary sediments were found to determine the position of soils at both levels of classification (reference groups, main and additional classifiers). The distribution of each of the reference groups is clearly related to the geomorphology of the valley. Arenosols and Cambisols form the soil cover of the floodplain terrace, while Fluvisols and Gleysols are found mainly in the floodplain.","PeriodicalId":52505,"journal":{"name":"Folia Oecologica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43818690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
