...。高速渡 輪所發出的聲響，亦遠高於沒有太多船隻出現的水域之背景噪音水平，此證明當 一些繁忙航道與海豚重要生境重疊，行經該航道的高速船所發出的聲響將大幅提 高水底噪音的水平，而影響海豚在該處的活動。由於這些船隻以高速航行，當它 們在短時間內靠近海豚時，牠們未必有時間作出合適的反應以遠離這些船隻；若 同時有數隻高速船在海豚周圍掠過，尤其是當這些船隻航行的速度、及與海豚保 持的距離經常改變以致難以揣測，海豚為要逃避船隻而所承受的壓力亦因而增 加，令牠們更易被高速船所撞擊，或逼使牠們放棄一些原適合作覓食活動的生境。 另一項有關高速渡輪對本地中華白海豚及江豚的影響評估發現，在 1999- 2010 年間，來...

... LEUNG, Phoebe SZE, Alfred WONG Butterfly Working Group 漁農自然護理署於2002年年底，在香港斑蝶越冬的主要停留地點 進行了「重複捕取」實驗，以了解越冬斑蝶的遷移路線及小冷水越冬群 落的族群動態。本文闡述實驗的主要結果並附討論。 Introduction Danaids (Family Danaidae 斑蝶科) are the only group of butterflies that may aggregate in large numbers to survive over the cold winter at their adult...

...。 在十二個月研究期間內，研究員共進行了 198 次樣條線船上調查，在全港十 個調查區航行 6,136.0 公里，並在船上共觀察到 181 群中華白海豚 (總數達 646 隻) 及 55 群江豚 (總數達 121 隻)。中華白海豚經常出沒在西大嶼山水域，較少在西南 大嶼山沿岸水域錄得其出沒記錄。相反，牠們甚少出現在南大嶼山水域的南部及 東部，並且在北大嶼山整片水域幾近絕跡。另一方面，江豚的目擊記錄主要集中 於大鴉洲附近一帶水域。 中華白海豚在 2022 年的重要棲身地，主要集中在西大嶼山近岸及西南大嶼山 西端的水域，主要在大澳半島與分流半島之間一帶。在過去十年，海豚在北大嶼 山水域的使用率大幅下降...
