The phenotypic parameters studied include the aerial vegetative part of the leaves and the flowers. The existing relationships between the ecological conditions and the genetic dynamics expressed by the morphological polymorphism of the populations concerned have been established. Results obtained allowed us to admit that we have two ecotypes in Algeria: the first one has five flowers per capitulum and can be found at the level of the three bioclimatic floors studied; whereas the second one has eight flowers per capitulum occupying only the territories with a Saharan climate. The analysis of variance (ANOVA) and UPGMA dendrogram allowed us to observe a very significant intra- and inter-population morphological polymorphism at the level of each site and between the different sites. This wide variability thus observed for A. herba-alba could help research on a large collection of individuals and therefore to choose the most effective ecotypes in order to reintroduce this species in the steppe areas of Algeria.","PeriodicalId":53683,"journal":{"name":"Ekologia Bratislava","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135685720","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 Coastal Law 02-02 was established to achieve this goal by using geographic information system (GIS) and remote sensing to assess the degree of implementation of this law on the ground. This evaluation highlighted a significant evolution of land use in the coastal zone of El Tarf province over a period of 32 years, from 1990 to 2022. In 1990, the area was predominantly forested (55.08%) with a proportion of agricultural land of 27.26% and a significant portion of wetland areas (17.26%). Over time, the forested area decreased to reach 48.58% in 2022, while agricultural land and urban areas increased. This evolution suggests increasing pressure on natural resources, with potential implications for the environment and biodiversity of the region. Despite the 2002 Coastal Law 02-02s which sets specific provisions for the protection and enhancement of the coastline, it is important to emphasize the importance of sustainable management of natural resources and land use in the region. It is essential to implement measures to protect the fragile ecosystems of the region and ensure the sustainability of natural resource use to preserve the environment and biodiversity of the region for future generations. This analysis could also eventually enable decision-makers to have supporting elements to evolve the law 02.02 with the aim of better preserving the coastal area.","PeriodicalId":53683,"journal":{"name":"Ekologia Bratislava","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135686225","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}

One effective way to create green spaces is by establishing meadows filled with diverse plant species. These meadows can provide numerous benefits, such as aiding pollinator conservation, improving air and water quality, and increasing biodiversity. Therefore, creating these meadows is an important component of urban ecology. Seven types of flower meadow mixtures from a Czech company were sown in 12 plots within the Hliník Urban Park in Nové Zámky, Slovak Republic. The development of the vegetation and the impact of maintenance management and climatic factors were monitored during the vegetation period of 2021‒2022, and the plots are still being monitored. The results of the flower meadow research in 2021 showed that improper maintenance and insufficient precipitation negatively influenced the vegetation’s development. Grasses were most prevalent during the summer months, while legumes were more common in the spring months. The analysis of the plots revealed that four out of 12 plots were dominated by annuals and grasses, which were the most abundant throughout the entire vegetation period. In 2022, it was observed that grasses were most prevalent in May, legumes in June and July, and annuals occurred sporadically in all plots. Insufficient precipitation and high temperatures in 2022 created unfavorable conditions for the thriving of the flower meadow vegetation, resulting in a high proportion of opportunistic species. Due to the impact of stress factors, the vegetation in the plots dried up.","PeriodicalId":53683,"journal":{"name":"Ekologia Bratislava","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135686219","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 region has one of the most important hydrographic systems in Algeria and a wide range of exceptional wetlands due to its important rainfall regime. A lack of studies, especially in the western part of the region (Tizi Ouzou), prompts a specific inventory and ecological analysis of the Odonata population over a period of 6 months (from April to September 2021). Forty species of Odonata have been recorded in Kabylia, of which Pyrrhosoma nymphula represents a new record for Algeria, raising the reference list to 64 species. There are four northern African endemic species and among these, we report on the rediscovery of the critically endangered (EN) Calopteryx exul in Algeria, recorded in the 19th century and deemed to have been extinct after an absence of more than a century; Gomphus lucasii is assessed as vulnerable (VU) and Enallagma deserti and Platycnemis subdilatata are judged as least concern (LC).","PeriodicalId":53683,"journal":{"name":"Ekologia Bratislava","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135686228","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}

Their presence and distribution depends on water temperature and transparency, nutrient content, conductivity, pH, chemical composition and water circulation. Therefore, the goal of our research was to determine the influence and interrelationship of physicochemical parameters of water on the content of photosynthetic pigments in aquatic macrophytes of Lake Necik, in the Ramsar area of Bardača (Republic of Srpska). Content of total chlorophyll ( a + b ) during the growing season (June–October) ranged from 0.231 to 1.145 mg g −1 FW in Phragmites communis Trin. ex Steud., from 0.061 to 0.541 mg g −1 FW in Salvinia natans L. (All.), from 0.063 to 0.626 mg g −1 FW in Utricularia vulgaris L. and from 0.063 to 0.443 mg g −1 FW in Ceratophyllum demersum L. Research has shown that floating and submerged macrophytes have a lower ratio of chlorophyll a / b compared to emergent hydrophytes, which is most likely the result of stress caused by increased light intensity and temperature. Seasonal variations in the content of photosynthetic pigments indicated that the species Phragmites communis proved to be more tolerant to the stress caused by the influence of various abiotic factors, while Salvinia natans proved to be more sensitive. Spearmon’s correlation coefficient of the physicochemical parameters of water and the concentration of photosynthetic pigments of macrophytes showed a significant influence of certain abiotic factors (temperature, transparency and nutrients) on the content of pigments in the leaves of Phragmites communis, Salvinia natans , Utricularia vulgaris and Ceratophyllum demersum L.","PeriodicalId":53683,"journal":{"name":"Ekologia Bratislava","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135686217","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}

To address this, sustainable management of protected areas is essential. This study aims to develop a methodology for monitoring and assessing levels of nocturnal anthropogenic aggression in the Comoé National Park (CNP) in Côte d’Ivoire. By using geospatial data from the Day/Night Band of the Visible Infrared Imaging Radiometer Suite (VIIRS/DNB), the study characterizes the nocturnal anthropization of CNP through the use of several indices. First, light reflectance density is used to identify nighttime light emission foci. Second, the lighted area density index (LADI) is employed to understand the nature of nocturnal activities taking place within CNP, as indicated by artificial light at night (ALAN). Finally, the light intensity index (LII) is used to evaluate the degree of influence of nocturnal anthropogenic activities on biodiversity. The study also found important activities through LADI and observed a high level of light pollution in CNP. Ultimately, the findings of this study indicate that there is a significant level of nocturnal anthropization within CNP, highlighting the need for effective management and conservation efforts in the area.","PeriodicalId":53683,"journal":{"name":"Ekologia Bratislava","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135686099","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}
