中文摘要 | 鑑於臺灣海岸水泥化情形十分嚴重,包括漁港、海堤及消波塊等,這些人工基質除了阻礙了人們親近海洋的機會外,更破壞了潛水生態或潮間帶的自然棲地,使許多海洋生物的成體或幼體失去了庇護所而快速滅絕。本文針對後壁湖海岸,就現存同為硬基質之人工海岸與天然岩礁上附生軟體動物之生物量的異同,探討人工基質對潛水生態之影響。 第一季軟體動物採樣12科18種161個體(2.24 ind/m2),第二季採樣13科42種1268個體,整合兩次採樣結果,共採得軟體動物三綱14科52種,第一季採樣數量較低,可能與颱風影響有關。 人工海岸物種較少,但是個體累積趨勢快,顯示天然海岸有較高的歧異度及均勻度,而人工海岸有優勢物種出現為顆粒玉黍螺,本種與其他玉黍螺都是同時分佈於人工海岸及天然海岸廣佈種。然而人工海岸的寶螺科、蟹守螺科、芋螺及芝麻螺科等物種消失,而骨螺科大部分種類消失僅剩結螺。 物種食性分析,物種種類食性以藻食性最多(44%),其次依序為肉食性(28%)、濾食性(11%)、蟲食性(11%)及草食性(6%),南北兩區物種食性組成相似。 |
英文摘要 | Following the progressive expansion of human populations, the number of artificial habitats is increasing in shallow water of Taiwan coastal area. The range from seabreak, jetties and pier pilings to seawall. The potential impact of variety of artificial surface has yet to be thoroughly assessed in Taiwan. There are few researches of the effect of building components of the artificial construct. The direct effects vary from damage to vulnerable benthic assemblages, such as coral reefs, seagrasses and molluscan from habitat destroyed. It is important to evaluate the ecology value of the artificial surfaces as habitat for intertidal assemblages, in comparison to the natural surfaces they have replaced. This study aims to assess the differences among nature and artificial habitats in Taiwan. In term of species composition, relative abundance and scales of variability in space. There are three class 27 families, 142 species were collected from 5 sites. The nature habitat were appear higher diversity and eveness. The artificial habitats were shown lower species number. The artificial habitats were found dominate species such as littorinids. The artificial habitats were shown lower abundance except Haiko. |
