In its typical robust form with strongly squarrose branch leaves, Sphagnum squarrosum is unmistakeable. Smaller forms such as occur in the higher mountains may be difficult to identify accurately without careful examination of microscopic details. In the tundra there sometimes occur large, terete forms of S. squarrosum but these are usually considerably more robust than S. teres. See also discussion under 14. S. strictum.

Rašeliník kostrbatý ( Czech )

provided by wikipedia CZ

Rašeliník kostrbatý (Sphagnum squarrosum) roste ve volných, rozlehlých, houbově měkkých, světle zelených až slabě modrozelených polštářích. Patří do čeledi rašeliníkovitých.

Popis

Rostlina mohutná, většinou rozvolněná, 7–25 cm dlouhá, bledě zelená, sytě zelená až nahnědlá, někdy poněkud naoranžovělá, s běžně vyklenutou hlavičkou. Hojně se rozmnožuje četnými výtrusy. Silné a vzpřímené lodyžky jsou tmavě zelené, 10–20 cm vysoké, větvené většinou jen v dolní části. Lístky na lodyžkách jsou spirálovitě uspořádané, volně odstávají od lodyhy a taškovitě se překrývají. Jsou 2–3 mm dlouhé, hladké se zaokrouhlenou, třásnitou špičkou jazykového tvaru. Lístky větví jsou kratší (1–3 mm), podlouhlé, ztloustlé, vodorovně odstálé a s poněkud ohnutou špičkou. Dobře se rozrůstá vegetativně.

Rašeliník kostrbatý je jednodomý, jeho sporogon je tvořen asi 10 mm dlouhým štětem a dlouze stopkatou, kulovitou, tmavohnědou tobolkou, z počátku zakrytou kalyptrou. Vyrůstá ze samičích větví v horní části lodyžek.

Nejlépe ze všech mechů dokáže zadržovat vodu. Odspodu odumírá, ale nahoře stále dorůstá, může tak tvořit velké plochy, až desítky metrů.

Rozšíření

S rašeliníkem kostrbatým se nikdy nesetkáme na rašeliništích mimo les. Je to typicky lesní druh, který roste ve velkých a rozlehlých kobercích, na vlhkých lesních půdách, bažinách a mokřadech se slabě kyselou reakcí a s bohatstvím půdních živin. Je zvláště hojný v okolí lesních potůčků i v blízkosti stojatých vod. Nejvíce rozšířen v nadmořských výškách od 500–1500 m. V ČR poměrně běžný druh v rašeliništích ve vyšších polohách. V pohraničních horách Čech, v Brdech, na Českomoravské vrchovině, v Hrubém Jeseníku a Beskydech poměrně častý druh, v ostatních částech republiky vzácnější.

Možnost záměny

V terénu dobře rozpoznatelný a těžko zaměnitelný druh díky kostrbatě odstálým větevním lístkům. Kostrbatě odstálé lístky má i příbuzný rašeliník obrlý (Sphagnum teres), který je ovšem mnohem štíhlejší a bývá žlutavě nebo žlutohnědě zbarvený, dále dává přednost minerálně bohatším stanovištím.

Sphagnum squarrosum

provided by wikipedia EN

Sphagnum squarrosum, commonly known as the spiky bog-moss[1] or spreading-leaved bog moss[2] is a species of moss which grows in nutrient-rich, damp soil. Typical habitats include woodland, the banks of streams and ditches; it can even be found at high altitude in damp cirques. The species often grows near sedges (Carex), rushes (Juncus) or purple moor grass (Molinia caerulea).[1]

Sphagnum squarrosum plants are green, and have the appearance of spikiness.[1]

Sphagnum squarrosum ( French )

provided by wikipedia FR

Sphagnum squarrosum (ou Sphaigne squarreuse) est une bryophyte de la famille des Sphagnacées[1] (spiky bog-moss[2] ou spreading-leaved bog moss[3]).

Description

Cette mousse a une couleur vert tendre quand elle est normalement humide.

Habitat

Cette espèce apprécie les sols et substrats acides, riches en matière organique nutriments et très humides
Ses habitats typiques incluent les bois humides et tourbeux riche en bois-morts, certains fossés et les banquettes de cours d'eau rapides (torrents, cascades…), jusqu'à haute altitude. On la trouve souvent en milieux paratourbeux, associée à des Caricaies, des tapis de joncs ou des étendues ou touradons de molinie bleue (Molinia caerulea)[2].

Une analyse génétique récente (2006) a montré (sur la base des haplotypes chloroplastiques) que cette espèce est plus ubiquiste que S. fimbriatum qui montre elle de fortes affinités biogéographiques[4]. Une hypothèse est que S. fimbriatum a survécu aux dernières glaciations en zone atlantique plutôt littorale en Europe, alors que S squarrosum a bénéficié de nombreux refuges dans toute l'Europe. L'existence d'un haplotype dominant de S. fimbriatum dans presque toute l'Europe suggère une recolonisation rapide de certains milieux par cette espèce à partir de la fin du maximum glaciaire (il y a environ 10 000 ans) ; Une capacité colonisatrice élevé de S. fimbriatum serait alors une caractéristique inhérente et la récente expansion de en Europe pourrait être une réponse au changement climatique.

Services écosystémiques

En se décomposant (mal) elle contribue à former la tourbe[5] et joue donc un rôle en matière de puits de carbone et pour la cosnervation de l'eau, les tourbières jouant souvent un rôle tampon important.

écologie

  • Cette espèce a une croissance rapide, et comme toutes les espèces des genres Sphagnum et Polytrichum là où elles s'installent tendent à augmenter et entretenir l'acidité du milieu[6]. Elle a une capacité d'acidification particulièrement élevée[7], ce qui est sans doute une manière d'éliminer d'autres plantes ne supportant pas cette acidité. (y compris d'autres mousses telles que Sphagnum scorpioides[8])
  • Dans les régions circum polaires, elle peut être parasitée par Discinella schimperi[9].

État des populations, menaces

Comme toutes les plantes de tourbières, cette espèce est menacée par le drainage des zones humides, et pourrait être affectée par les conséquences du réchauffement climatique.

L'eutrophisation générale des milieux et localement leur dystrophisation par la diffusion d'azote (sous forme d'engrais agricoles notamment[10]) est une autre cause de régression[11].
