... Specialist Working Group 踏進紅樹林,其中一類最常見的生物必然是那些遍佈泥灘及紅樹上、形態相似的滙螺(台灣稱海蜷螺)。最新 的分類研究指出本港有 12 種滙螺。本文旨在重整本港有關滙螺的紀錄及描述其特徵,方便研究人員辨別這群容易 混淆的生物。 Introduction For marine organisms, mangroves are a physically challenging habitat, characterized by acidic and anoxic soil, a three-dimensional structure of mangrove stands...

...內,人類進食受 污染貝類便有可能出現中毒症候。常見的貝類中毒包括可致命的神經紊亂麻痺性貝類中毒、引致腸 胃不適的下痢性貝類中毒、引致腸胃不適和神經紊亂的神經性貝類中毒,以及引致腸胃及神經系統 失調的失憶性貝類中毒,嚴重者可能致命。 只有少數藻類曾導致大量野生和養殖魚類死亡。魚類透過直接攝入受污染水體中的毒素或食物鏈造 成生物積聚,均可能中毒死亡。此外藻類毒素亦會刺激魚鰓製造大量黏液,或直接堵塞魚鰓妨礙吸 氧,令魚類窒息而死。大規模和高濃度的藻華會耗盡環境中的養份,令微藻下沉,細菌分解微藻導 致底層氧氣枯竭,水中含氧量低於每公升 2 毫克時會出現低氧現象,當水中的含氧量接近零時便會 出現缺氧。由...
