K\u0159e\u010dek)<\/h6>\n<p>On 25th January 2024, a\u00a0seminar Meeting of\u00a0researchers in\u00a0the\u00a0Jizera Mountains was held in\u00a0the\u00a0conference centre of\u00a0T. G. Masaryk Water Research Institute (TGM WRI) in\u00a0Prague. It presented (mainly long-term) research projects implemented in\u00a0the\u00a0Jizera Mountains and focused on atmospheric precipitation, forest soils and forests, waters and their biota in\u00a0recent decades, i.e. from peak acidification to current phenomena associated with climate change. However, no less important was the\u00a0personal meeting of\u00a0people who research, permanently work or live in\u00a0the\u00a0Jizera Mountains and are interested in\u00a0the\u00a0development of\u00a0the\u00a0situation in\u00a0this area, as well as the\u00a0final debate open to all.<\/p>\n<p>Apart from researchers from the\u00a0Museum of\u00a0North Bohemia in\u00a0Liberec, universities and academic and non-academic research institutions, we therefore also invited representatives of\u00a0nature conservation authorities (primarily Jizera Mountains PLA Administration, but also Krkono\u0161e National Park, \u0160umava National Park, and the\u00a0Nature Conservation Agency of\u00a0the\u00a0Czech Republic), Povod\u00ed Labe, state enterprise, water industry-oriented companies (W&amp;ET Team, Severo\u010desk\u00e1 servisn\u00ed) and water management (DHI), as well as the\u00a0Czech Fishery Association. The\u00a0meeting was also attended by university students, representatives of\u00a0the\u00a0Czech Society for Ornithology and ecological consultancy (EKOEX Jihlava), a\u00a0volunteer ranger working for the\u00a0Jizera Mountains PLA Administration, and others. Together with former and current TGM WRI employees, over a\u00a0hundred people gathered in\u00a0the\u00a0hall.<\/p>\n<p>As a\u00a0hydrobiologist at TGM WRI, who has long been involved in\u00a0the\u00a0study of\u00a0water reservoirs on the\u00a0upper plateau of\u00a0the\u00a0Jizera Mountains within\u00a0the\u00a0long-term concept of\u00a0the\u00a0development of\u00a0a research organization (DKRVO), I prepared the\u00a0seminar with the\u00a0organizational and financial support of\u00a0the\u00a0Institute and a\u00a0financial contribution from the\u00a0company Aon Central and Eastern Europe. I was inspired by the\u00a0previous seminar, Jizera Mountains \u2013 meeting across scientific disciplines, which was organized in\u00a0December 2012 at the\u00a0Faculty of\u00a0Agrobiology, Food and Natural Resources of\u00a0the\u00a0Czech University of\u00a0Life Sciences in\u00a0Prague (FAPPZ CZU) by prof. Radka Kode\u0161ov\u00e1 (Department of\u00a0Pedology and Soil Protection, FAPPZ CZU) and Mgr. \u0160imon Bercha (Department of\u00a0Applied Hydrology, CHMI)\u00a0[1]. Its originally intended focus on hydrology and soil hydrology was expanded to include other research fields, as\u00a0well as the\u00a0activities of\u00a0various public administration institutions in\u00a0the\u00a0Jizera Mountains, making this informal seminar a\u00a0very interesting event. The\u00a0second meeting of\u00a0the\u00a0Jizera Mountains researchers, defined by a\u00a0professional focus on precipitation, waters, soils, and forests, was also prepared in\u00a0such a\u00a0way that, despite the\u00a0large number of\u00a0participants and the\u00a0number of\u00a0lectures, it retained an informal and friendly character.<\/p>\n<p>The\u00a0Jizera Mountains, part of\u00a0the\u00a0so-called Black Triangle, are one of\u00a0the\u00a0regions of\u00a0the\u00a0world that were most affected by acidic atmospheric deposition in\u00a0the\u00a0second half of\u00a0the\u00a020th century. Despite significant recovery from acidification and apparent restoration of\u00a0waters and forests, this area faces many old and new issues. The\u00a0main\u00a0purpose of\u00a0the\u00a0meeting of\u00a0experts who have been participating in\u00a0its research and administration for a\u00a0long time was therefore for them to find out about each other, their work and results \u2013 taking into account the\u00a0fact that many of\u00a0them are already close to retirement or already retired. It was also intended to be an inspiration for further work and collaboration.<\/p>\n<p>Why was the seminar on the issue of the Jizera Mountains held under the Baba folly on the Vltava promontory in Prague? In addition to the simple reason that TGM WRI in Prague\u2019s Podbaba is now my workplace, which had supported me in the later years of my thirty-year research on the Jizera Mountains reservoirs and which has a suitable facility for such a meeting,\u00a0there are also other connections. Between 1942 and 1964, the\u00a0first limnological study of\u00a0all reservoirs in\u00a0the\u00a0Labe and Lu\u017eick\u00e1 Nisa basins was being developed in\u00a0the\u00a0Institute by Dr. V\u011bra \u0158eh\u00e1\u010dkov\u00e1 (later Rozmajzlov\u00e1)\u00a0[2]. The\u00a0results regarding the\u00a0water chemistry of\u00a0the\u00a0Bed\u0159ichov and Sou\u0161 reservoirs confirm their high acidity, at that time still attributed only to the\u00a0peaty character of\u00a0the\u00a0basin. The\u00a0only data on the\u00a0water chemistry of\u00a0the\u00a0Jizera Mountains reservoirs in\u00a0the\u00a01980s, summarized by Ing. Martina Bedn\u00e1\u0159ov\u00e1\u00a0[3, 4], are the\u00a0output of\u00a0projects of\u00a0Ing.\u00a0Ladislav Ka\u0161p\u00e1rek from TGM WRI\u00a0[5]. The\u00a0research of\u00a0his working group (similarly as\u00a0in\u00a0the\u00a0case of\u00a0the\u00a0team of\u00a0Ing. Libu\u0161e Buben\u00ed\u010dkov\u00e1 from CHMI) dealt with the\u00a0effect of\u00a0deforestation on the\u00a0hydrology and quality of\u00a0surface waters in\u00a0the\u00a0headwater area of\u00a0the\u00a0Jizera Mountains. This immission calamity as well as extremely low water pH values in\u00a0the\u00a01980s were already clearly associated with acid rain.<\/p>\n<a href=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-2.jpg\" rel=\"shadowbox[sbpost-29599];player=img;\"><img decoding=\"async\" class=\"alignnone wp-image-29453 size-full lazyload\" data-src=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-2.jpg\" alt=\"\" width=\"800\" height=\"409\" data-srcset=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-2.jpg 800w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-2-300x153.jpg 300w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-2-768x393.jpg 768w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 800px; --smush-placeholder-aspect-ratio: 800\/409;\" \/><\/a>\n<h6>Fig. 2.

(Photo: V. Mr\u00e1zek)<\/h6>\n<p>In\u00a0the\u00a0course of\u00a0the\u00a0day, which was started with humour and ease by TGM WRI director Ing. Tom\u00e1\u0161 Fojt\u00edk, 22 short lectures were given. They were divided into four specialist sections \u2013 hydrology and hydrochemistry, forest soils and forests, waters, and water biota. Chairing the\u00a0sections were Dr.\u00a0V\u00edt Kode\u0161\u00a0(CHMI), doc. Pavel Jurajda (Institute of\u00a0Vertebrate Biology, CAS), Dr.\u00a0Jan (\u201cJe\u0148\u00fdk\u201d) Hofmeister (Faculty of\u00a0Forestry and Wood Sciences of\u00a0the\u00a0Czech University of\u00a0Life Sciences in\u00a0Prague, FLD CZU), and Ing. Pavel Voni\u010dka (Museum of\u00a0North Bohemia, Liberec). Thanks to their strict time monitoring, there was room for refreshments, meetings, and offstage discussions during the\u00a0day. a\u00a0short film with commentary by doc. Petr Dolej\u0161 (W&amp;ET Team) from his flight over the\u00a0Jizera Mountains reservoirs was also shown.<\/p>\n<p>It was a\u00a0great honour to be able to welcome the\u00a0leading ladies of\u00a0Czech hydrology to the\u00a0seminar \u2013 prof. Milena C\u00edslerov\u00e1 (Faculty of\u00a0Civil Engineering, CTU), Ing. Libu\u0161e Buben\u00ed\u010dkov\u00e1 (CHMI), Ing. Alena Kulasov\u00e1 (TGM WRI), and prof. Radka Kode\u0161ov\u00e1 (FAPPZ CZU). Among the\u00a0special guests who did not make a\u00a0contribution were also the\u00a0head of\u00a0the\u00a0Bed\u0159ichov dam, Petr Noswitz (Povod\u00ed Labe, state enterprise), Dr. Miroslav \u0160v\u00e1tora (Faculty of\u00a0Science, Charles University), Ing.

Jaroslav Vrba (Faculty of\u00a0Science, University of\u00a0South Bohemia) and former colleagues Rudolf Hancvencl (CHMI), Ing.\u00a0Vladim\u00edr Vr\u0161ovsk\u00fd (Jizersk\u00e9 hory PLA Administration), and Ing. Petr Navr\u00e1til (Forest Management Institute, \u00daH\u00daL). I gladly passed on greetings from Dr.\u00a0Miloslav Nevrl\u00fd, Roman Karpa\u0161, Dr. Franti\u0161ek Pelc (NCA CR Director), Dr.\u00a0Daniela Fottov\u00e1, Ing. Miroslav Tesa\u0159 (Institute of\u00a0Hydrodynamics, CAS), doc.\u00a0Iva H\u016fnov\u00e1 (CHMI), and Ing. Jana Hub\u00e1\u010dkov\u00e1, who are also closely connected with the\u00a0Jizera Mountains, but could not participate in\u00a0person.<\/p>\n<p>In the hydrology and hydrochemistry section, Ing. Ladislav Ka\u0161p\u00e1rek (TGM WRI) pointed out the contribution of experimental basins in the Jizera and other mountains to the substantial reduction of estimates of the extent\u00a0to which deforestation will affect changes in\u00a0mean and maximum flows. His former colleague, Ing. Martina Bedn\u00e1\u0159ov\u00e1, described the\u00a0slow deterioration of\u00a0surface water quality (in\u00a0the\u00a0sense of\u00a0acidification and leaching of\u00a0metals from soils) between 1982 and 1987, which occurred due to the\u00a0gradual exhaustion of\u00a0the\u00a0acid-neutralizing capacity of\u00a0waters and soils. Mgr. \u0160imon Bercha from the\u00a0Department of\u00a0Applied Hydrology, CHMI, briefly presented the\u00a0current CHMI activities in\u00a0experimental basins in\u00a0the\u00a0Jizera Mountains. As for experts from the\u00a0Faculty of\u00a0Civil Engineering, CTU, doc. Jarom\u00edr Du\u0161ek presented results of\u00a0modelling runoff dynamics and isotope transport in\u00a0a slope soil; doc. Martin\u00a0\u0160anda with prof. Milena C\u00edslerov\u00e1 presented a\u00a0study of\u00a0water flow under the\u00a0surface within\u00a0the\u00a0hydrological cycle of\u00a0small mountain\u00a0basins (especially the\u00a0Uhl\u00ed\u0159sk\u00e1 and Velk\u00e1 Jizersk\u00e1 louka basins). In\u00a0his lecture, Dr. Filip Oulehle (Czech Geological Survey and Global Change Research Institute, CAS) addressed small GEOMON (GEOchemical MONitoring) basins in\u00a0our country and their importance for understanding landscape hydrology and biogeochemistry. Of\u00a0great interest was the\u00a0lecture by prof. Jakub Hru\u0161ka from the\u00a0same team on the\u00a0results of\u00a0long-term monitoring of\u00a0the\u00a0Uhl\u00ed\u0159sk\u00e1 basin\u00a0on the\u00a0\u010cern\u00e1 Nisa river (precipitation and river water chemistry), with a\u00a0warning about persistent issues associated with acidification as well as new issues caused by climate change.<\/p>\n<a href=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-3.jpg\" rel=\"shadowbox[sbpost-29599];player=img;\"><img decoding=\"async\" class=\"alignnone wp-image-29451 size-full lazyload\" data-src=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-3.jpg\" alt=\"\" width=\"800\" height=\"409\" data-srcset=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-3.jpg 800w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-3-300x153.jpg 300w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-3-768x393.jpg 768w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 800px; --smush-placeholder-aspect-ratio: 800\/409;\" \/><\/a>\n<h6>Fig. 3.

The film screening was followed by a comprehensive lecture by Dr. Pavel Dobi\u00e1\u0161 and doc. Petr Dolej\u0161 from the W&amp;ET Team company, mapping the development of technology in the Sou\u0161\u00a0and Bed\u0159ichov water treatment plants over the\u00a0last 30 years. The\u00a0treatment process was complicated here by a\u00a0high content of\u00a0humic substances and dissolved aluminium, and in\u00a0certain\u00a0periods also with a\u00a0large concentration of\u00a0dinoflagellates and cyanobacteria (<em>Merismopedia<\/em> sp.) in\u00a0the\u00a0raw water of\u00a0the\u00a0Sou\u0161 and Josef\u016fv D\u016fl reservoirs. Both treatment plants underwent significant modernization and transition from direct filtration to flotation-filtration treatment plants, with a\u00a0higher separation efficiency and thus also a\u00a0higher safety of\u00a0drinking water production. No less extensive was the\u00a0presentation of\u00a0four decades of\u00a0monitoring of\u00a0drinking water reservoirs in\u00a0the\u00a0Jizera Mountains, Sou\u0161 and Josef\u016fv D\u016fl, by their manager, Povod\u00ed Labe, state enterprise. Ing.

In\u00a0addition to the\u00a0basic water chemistry, they commented on the\u00a0structure and abundance of\u00a0phytoplankton, including the\u00a0excessive development of\u00a0pico-sized algae (<em>Merismopedia<\/em> sp.) in\u00a0Josef\u016fv D\u016fl over the\u00a0last 15 years.<\/p>\n<p>Dr. Lenka Proch\u00e1zkov\u00e1 (Faculty of\u00a0Science, Charles University) and Dr. Zuzana Ho\u0159ick\u00e1 (TGM WRI) showed the\u00a0development of\u00a0phytoplankton and zooplankton of\u00a0the\u00a0Bed\u0159ichov, Sou\u0161, and Josef\u016fv D\u016fl water reservoirs between 1992 and 2021 with the\u00a0gradual recovery from acidification. Their lectures were supplemented by the\u00a0enthusiastic contribution of\u00a0Dr. Martin\u00a0Pusztai (CXI and Faculty of\u00a0Science, TUL, and Faculty of\u00a0Science, Charles University) about the\u00a0significance and beauty of\u00a0Chrysophyceae, which are the\u00a0most numerous group of\u00a0planktonic algae in\u00a0Josef\u016fv D\u016fl and Sou\u0161. Dr. Olga Lep\u0161ov\u00e1-Sk\u00e1celov\u00e1 (Faculty of\u00a0Science, University of\u00a0South Bohemia) contributed with a\u00a0study of\u00a0periphyton in\u00a0the\u00a0tributaries of\u00a0all three reservoirs in\u00a01996 and then in\u00a02008, when the\u00a0anthropogenic acidification had subsided, but the\u00a0unstable chemistry and natural acidity of\u00a0the\u00a0Jizera Mountains waters continued to manifest. Doc. Pavel Jurajda (on behalf of\u00a0the\u00a0team from Institute of\u00a0Vertebrate Biology, CAS, and Povod\u00ed Labe, state enterprise) spoke about the\u00a0fish communities in\u00a0the\u00a0Sou\u0161 and Josef\u016fv D\u016fl drinking water reservoirs since 2016, mentioning the\u00a0results of\u00a0the\u00a0research by Dr. Miroslav \u0160v\u00e1tora (Faculty of\u00a0Science, Charles University) from 1997\u20132015 regarding the\u00a0successful reintroduction of\u00a0brook trout in\u00a0Bed\u0159ichov and Sou\u0161. Brook trout and brown trout are currently released in\u00a0Sou\u0161 (where the\u00a0share of\u00a0brown trout is increasing); brook trout, common minnow and (since 2023) also brown trout in\u00a0Josef\u016fv D\u016fl. On behalf of\u00a0his colleagues from Faculty of\u00a0Science, MUNI, and Faculty of\u00a0Science, University of\u00a0South Bohemia, Dr. Jan Sychra presented results of\u00a0the\u00a0study of\u00a0littoral communities of\u00a0invertebrates in\u00a0standing waters of\u00a0the\u00a0\u0160umava, Ore, and Jizera Mountains in\u00a0the\u00a0context of\u00a0their recovery from acidification. In\u00a0particular, he dealt with true bugs and water bugs (Heteroptera) of\u00a0the\u00a0Jizera Mountains. Together with Ing. Pavel Voni\u010dka (Museum of\u00a0North Bohemia, Liberec) and other collaborators, he proved that these mountains are extremely rich in\u00a0them\u00a0[7]. The\u00a0lecture part of\u00a0the\u00a0seminar was complemented by the\u00a0presentation of\u00a0doc.\u00a0Josef K\u0159e\u010dek (Faculty of\u00a0Civil Engineering, CTU) about the\u00a0Earthwatch project (as an example of\u00a0citizen science) applied in\u00a0the\u00a0multidisciplinary research in\u00a0the\u00a0Jizera Mountains basins.<\/p>\n<a href=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-4.jpg\" rel=\"shadowbox[sbpost-29599];player=img;\"><img decoding=\"async\" class=\"alignnone wp-image-29449 size-full lazyload\" data-src=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-4.jpg\" alt=\"\" width=\"800\" height=\"278\" data-srcset=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-4.jpg 800w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-4-300x104.jpg 300w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-4-768x267.jpg 768w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 800px; --smush-placeholder-aspect-ratio: 800\/278;\" \/><\/a>\n<h6>Fig. 4.

Typical brown waters of the Jizera Mts., rich in humic substances (Photo: D. Vondr\u00e1k)<\/h6>\n<p>To conclude the\u00a0event, a\u00a0discussion was opened about the\u00a0recent development and current state of\u00a0nature and tourism in\u00a0the\u00a0Jizera Mountains and about the\u00a0possibilities and difficult compromises in\u00a0planning the\u00a0future development. The\u00a0discussion was led by Ing. Ji\u0159\u00ed Hu\u0161ek (Director of\u00a0Jizera Mountains PLA Administration), prof. Lubo\u0161 Bor\u016fvka (FAPPZ CZU), prof. Jakub Hru\u0161ka (Czech Geological Survey and Global Change Research Institute, CAS), doc. Ivan Kune\u0161 (FLD CZU), and Dr. Jan Sychra (Faculty of\u00a0Science, MUNI). The\u00a0starting point for the\u00a0questions and the\u00a0exchange of\u00a0views was the\u00a0fact that the\u00a0condition of\u00a0soils is still unfavourable, waters have only partially recovered from acidification, the\u00a0mountains are excessively burdened by tourists, and spruce monocultures are growing again\u00a0in\u00a0the\u00a0basins. The\u00a0fact that management of\u00a0this area is complex and creates potential conflict was manifested by some verbal arguments on the\u00a0usual topic of\u00a0ecology (more nature-friendly forest management) versus wood production. Nevertheless, there were also other, interesting and helpful contributions.<\/p>\n<p>The\u00a0opportunity to discuss and chat even after the\u00a0seminar was over was provided to some of\u00a0the\u00a0participants by the\u00a0\u201clobby\u201d \u2013 a\u00a0room provided by a\u00a0nearby restaurant.<\/p>\n<p>Despite the\u00a0rich and demanding programme, the\u00a0day-long meeting had a\u00a0good atmosphere and was met with a\u00a0warm response. Proceedings are being prepared from the\u00a0responses of\u00a0a questionnaire prepared for researchers and \u201cadministrators\u201d of\u00a0the\u00a0Jizera Mountains. The\u00a0questionnaire aimed mainly on their focus in\u00a0research or their role in\u00a0maintenance and management, on\u00a0the\u00a0results of\u00a0their work, and their opinion on the\u00a0current state of\u00a0the\u00a0mountains. It already seems that a\u00a0similar meeting could take place again, and even bring researchers back to the\u00a0Jizera Mountains. It will probably be organized by Jizera Mountains PLA Administration in\u00a02027 to mark the\u00a060th anniversary of\u00a0designation of\u00a0the\u00a0PLA.<\/p>\n<a href=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-9.jpg\" rel=\"shadowbox[sbpost-29599];player=img;\"><img decoding=\"async\" class=\"alignnone wp-image-29439 size-full lazyload\" data-src=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-9.jpg\" alt=\"\" width=\"800\" height=\"1786\" data-srcset=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-9.jpg 800w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-9-134x300.jpg 134w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-9-459x1024.jpg 459w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-9-768x1715.jpg 768w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2024\/06\/Jizerskohorsti-badatele-obr-9-688x1536.jpg 688w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 800px; --smush-placeholder-aspect-ratio: 800\/1786;\" \/><\/a>\n<h6 id=\"tw-target-text\" class=\"tw-data-text tw-text-large tw-ta\" dir=\"ltr\" data-placeholder=\"P\u0159eklad\" aria-label=\"P\u0159elo\u017een\u00fd text\" data-ved=\"2ahUKEwjgmIXwqYGIAxUl87sIHdg9BYsQ3ewLegQIBxAU\"><span class=\"Y2IQFc\" lang=\"en\">Fig. 9.
