predstavujú jednu z najstarších línií kvitnúcich rastlín, čo z nich robí dôležitý model pre štúdium evolúcie a prechod medzi primitívnymi a pokročilejšími krytosemennými rastlinami (Kerry A. Ford et all). Lekná sú typické s plávajúcimi listami, sú adaptované redukciou mechanických pletív, vysokým obsahom parenchýmu, schopnosťou tolerovať hypoxické . Fotosyntéza prebieha primárne v listoch hladine. Rozmnožuje sa entomofíliou – prostredníctvom chrobákov, múch, včiel. Je u nich častoá protogýnia – najprv dozrieva blizna, potom , čím sa eliminuje možné samoopelenie. Lekná stabilizujú sedimenty, poskytuje poskytuje mikrohabitaty. Majú význam v trofických reťazcoch.

Svoje vykoná indrodukcia nepôvodných druhov lekien. , výrazné zmeny teplôt a výšky vodných hladín narúšajú vývoj kvitnutia a rozmnožovania lekien (Wikipedia).

V strednej Európe sú bežné druhy: , Nuphar lutea, Nymphaea candida a . Lekná patria do čeľade Nymphaeaceae. Rod Nymphaea má vyše 50 druhov, z iných druhov treba spomenúť  (Wikipedia). V trópoch sa vyskytuje Nymphaea lotus a . Lekná sa vyznačujú podzemným rhizómom, z ktorého vyrastajú a listy (Wikipedia). Prezimujú práve v podobe rhizómu – podzemku. Na z vyvíjajúcich sa rhizómových púčikov vyrastajú nové listy a kvetné . pritom vytvárajú jemné až robustné listy, ktoré sa postupne plavia na hladine. Po odkvitnutí sa vytvára vodná tobolka s plávajúcimi semienkami, ktoré sa vo vode rozširujú.

Lekná sa môžu rozmnožovať aj vegetatívne rhizómani delením. Obľubujú stojaté alebo len mierne tečúce . Typické sú pre jazerá, , staré , tečúce pomalé kanály aj so stabilnou hladinou. Uprednostňujú hlbšiu vodu, optimálna hĺbka je 0,7 – 2,5 m (gardenersworld.com). Vyhovuje im dostatok slnečného žiarenia a . Potrebujú minimálne 4 – 6 hodín priameho slnka denne (upjs.sk). Substrát musí byť bohatý na živiny. je ideálne mierne kyslé až zásadité, okolo 6 – 7. Stabilné chemické podmienky, bez prudkých kolísaní prispievajú k hojnému kvitnutiu. Menším druhom Nymphaea candida, vyhovuje chladnejšia voda a vyššia nadmorská (pfaf.org).

Nymphaea alba sa vyskytuje v celej Európe, v časti severnej Afriky aj v Ázii od Blízkeho východu až po západné Himaláje (kew.org). Nuphar lutea sa vyskytuje od Atlantiku cez Európu do Sibíri a severnej Afriky. Mimo prirodzený areál sa lekná vysádzali ako okrasná zeleň a rozšírili sa do Severnej Ameriky a Oceánie. Nymphaea alba a Nuphar lutea sú v strednej Európe pôvodné druhy. Vyskytujú sa najmä v nížinách – v Podunajskej a Východoslovenskej nížine a v povodiach stredných riek (Wikipedia). Nymphaea candida a Nymphaea pumila sú na Slovensku veľmi vzácne, resp. známe historicky (kew.org).

Lekná sa objavovali v kultúrach mnohých civilizácií. Nymphaea alba malo významný duchovný a liečivý charakter v starovekom Egypte (Wikipedia). V európskej tradícii sú lekná symbolom čistoty a nevinnosti. Kultivar Nymphaea alba rosea – červené lekno z Fagertärnu – bolo dokonca takmer vyhubené kvôli zberu (Wikipedia). Červené listy žltého lekna sú heraldickým symbolom Frízie (Holandsko) a dokonca sa motív lekna objavuje v katedrálnej architektúre (Bristol, Westminster) (Wikipedia).

Water lilies represent one of the oldest lineages of flowering plants, making them an important model for studying the evolution of flowers and the transition between primitive and more advanced angiosperms (Kerry A. Ford et al.). Water lilies are typical hydrophytes with floating leaves, adapted through the reduction of mechanical tissues, a high proportion of parenchyma, and the ability to tolerate hypoxic sediments. Photosynthesis takes place primarily in leaves floating on the water surface.

They reproduce through entomophily, involving beetles, flies, and bees. Protogyny is common – the stigma matures before the pollen, which reduces the likelihood of self-pollination. Water lilies stabilize sediments and provide microhabitats, playing an important role in food chains.

Water lilies – genera Nymphaea and Nuphar – are aquatic plants with floating leaves and conspicuous flowers. They provide ecological services such as shading and shelter for aquatic organisms (gardenersworld.com). They are threatened by habitat degradation and pollution (). Deforestation, wetland drainage, river regulation, and dam construction all negatively affect water lilies. Eutrophication can lead to excessive growth of algae and , which thicken water bodies and cover floating leaves. Chemical pollution directly damages plants or reduces water quality. The introduction of non-native species also contributes to their decline. Climate change, including in temperature and water levels, disrupts flowering and reproduction cycles (Wikipedia).

In Central Europe, common species include Nymphaea alba, Nuphar lutea, Nymphaea candida, and Nuphar pumila. Water lilies belong to the family Nymphaeaceae. The genus Nymphaea contains more than 50 species, and related taxa include Nymphoides peltata (Wikipedia). In regions, species such as Nymphaea lotus and Nymphaea japonica occur.

Water lilies are characterized by an underground rhizome from which roots and leaves emerge (Wikipedia). They overwinter in the form of this rhizome. In spring, new leaves and flowering stems develop from rhizome buds. The shoots produce leaves that gradually float to the surface. After flowering, a water fruit develops containing floating seeds that disperse through water.

Water lilies can also reproduce vegetatively by rhizome division. They prefer standing or slowly flowing freshwater habitats such as lakes, pools, oxbow lakes, slow channels, and ponds with stable water levels. They favor deeper water, with an optimal depth of approximately 0.7–2.5 m (gardenersworld.com). They require sufficient sunlight and warm water, with at least 4–6 hours of direct sunlight daily (upjs.sk). The substrate should be nutrient-rich. The optimal water is slightly acidic to neutral, around 6–7. Stable chemical conditions without abrupt fluctuations support abundant flowering. Smaller species such as Nymphaea candida and Nymphaea pumila prefer cooler water and higher altitudes (pfaf.org).

Nymphaea alba occurs throughout Europe, parts of North Africa, and Asia from the Middle East to the western Himalayas (kew.org). Nuphar lutea is distributed from the Atlantic across Europe to Siberia and North Africa. Outside their native range, water lilies have been introduced as ornamental plants and have spread to and Oceania. Nymphaea alba and Nuphar lutea are native species in Central Europe, occurring mainly in lowland areas such as the Danubian and Eastern Slovak Lowlands and in river basins (Wikipedia). Nymphaea candida and Nymphaea pumila are very rare or historically recorded in (kew.org).

Water lilies have appeared in the cultures of many civilizations. Nymphaea alba had spiritual and medicinal significance in (Wikipedia). In European tradition, water lilies symbolize purity and innocence. The cultivar Nymphaea alba ‘rosea‘ – the red water lily from Fagertärn – was nearly exterminated due to overcollection (Wikipedia). The red leaves of the yellow water lily are a heraldic symbol of Friesland (Netherlands), and water lily motifs appear in cathedral architecture (Bristol, Westminster) (Wikipedia).

Water lily leaves reduce light penetration and regulate water temperature while providing shelter for amphibians, fish, and insects. Some species have gastronomic value, as their tubers and seeds are edible. Extracts from water lilies have traditionally been used in folk medicine and may have sedative or mildly hallucinogenic effects (gardenersworld.com).

Ryby

Ryby – Osteichthyes patrí do podkmeňa Stavovce – Vertebrata, kmeňa Chordáty – Chordates. Najväčšie čeľade sú Gobiidae, Cyprinidae, Cichlidae, Labridae, Loricariidae. Na zaradenie do jednotlivých skupín sú rôzne názory odborníkov, obecne o tom rozhodujú meristické znaky – počet lúčov v plutvách, počet šupín. Pre jednotlivé druhy je opísaný vzorec, ktorý popisuje tieto znaky.

Fish

Fish – Osteichthyes belongs to the subphylum Vertebrata, phylum Chordata. The largest families include Gobiidae, Cyprinidae, Cichlidae, Labridae, Loricariidae. Various opinions among experts exist regarding the classification into individual groups, generally decided based on meristic characters such as the number of rays in the fins, and the number of scales. Each species has a described pattern that outlines these characteristics.

Ichthyology is the science dealing with fish.
