Nejmenší známý plaz na světě

nejmenší chameleon - Brookesia nana
Latinsky: 
Brookesia nana

nejmenším zatím objeveným plazem je chameleon (Brookesia nana). Samec nově objeveného druhu měří pouze 21,6mm na délku (délka i ocasem), samice měřila 28,9mm. 
Vědci objevili chameleona v pralese na severu ostrova Madagaskar. V současné době jsou známy pouze dva exempláře tohoto druhu a moc se toho o jejich životě zatím neví. 
Odborníci se domnívají, že se živí pravděpodobně roztoči a dalšími miniaturními bezobratlými živočichy. Přes den zřejmě hledají potravu na zemi a na noc se ukrývají na stéblech trávy.

Proč se vyvinul postupně do tak malých rozměrů je možná proto, že malé druhy chameleonů jsou schopny obecně lépe ovládat svůj jazyk při lovu potravy, a také, že jsou schopny ho "vystřelit" až na vzdálenost 2,5x násobku své délky. Jazyk malého chameleona se potom pohybuje rychlostí cca 2 590 m/sˉ², jinak řečeno jeho jazyk by překonal za jednu sekundu vzdálenost 2,5km.

Další možností je, že se zde uplatňuje tzv. Fosterovo ostrovní pravidlo. Tato teorie evoluční biologie má za to, že některé (velké) druhy zvířat mají v uzavřeném ekosystému ostrovů tendenci se mezigeneračně zmenšovat, a naopak jiné druhy zvětšovat. U velkých druhů zmenšování souvisí např. s dostatkem zdroje potravy = menší druhy mají nižší energetické nároky. U malých druhů jako jsou např. hlodavci je zvětšování způsobováno hlavně nedostatkem predátorů v místě jejich působení.  Takový druh pak nepotřebuje být menší a tím pádem rychlejší a obratnější.

Oblast, kde se miniauturní chameleon Brookesia nana vyskytuje, zahrnula Madagaskarská vláda do seznamu chráněných území. Můžeme tak doufat, že tento zajímavý plaz nevyhyne.

戦後には共産主義国家を広げないためにロシア革命に内政干渉を行い、他の列強と共にシベリア出兵を開始したが、1920年代後半には大恐慌で大打撃をこうむった。戦後は、高度経済成長による工業化や、中国等新興国の安い繊維製品の輸入増加で製造業での地位は低下している。 19世紀後半には、鉄鋼業や石油業が繁栄したことによってアメリカ経済が大きく躍進することになった。後にブースター化して一部のパーツの色などの仕様を変更して再発売したプレミアムリターンズ第1弾としても登場。海外からも気軽に参加できる仕様となっています。 インデックス」および「日経平均株価」を継続的に公表する義務を負うものではなく、公表の誤謬、遅延又は中断に関して、責任を負わない。

These two amendments resulted in FDA involvement in pesticide regulation.
