Abstract
The non-indigenous and invasive calcareous sponge Paraleucilla magna Klautau, Monteiro & Borojevic, 2004 has been detected for the first time on the Algerian coast. The species has been recorded at high abundance in Algiers Port (Algiers) and in Pisan Island (Béjaïa) during spring 2018. It was present from 2 m to 20 m of depth at the community of seaweeds with filter feeders established on artificial hard substrates and on rocky boulders. Total of 172 individuals were recorded not exceeding 5 cm in height. Anthropogenic activities such as aquaculture farms or shipping traffic might be important vectors or act as stepping-stones in further expansion of Paraleucilla magna.Additional recording of the species adds to the knowledge of its biogeography distribution, biology and ecology in the Mediterranean and may improve selection of key geographical sites for future monitoring on the species proliferation and expansion.
2004年,在阿尔及利亚海岸首次发现了非本土和入侵性钙质海绵Paraleucilla magna Klautau,Monteiro&Borojevic。2018年春季,该物种在阿尔及尔港(阿尔及尔)和皮桑岛(贝亚)被记录为高丰度物种。它存在于2米至20米深的海藻群落中,滤食性动物建立在人造硬质基质和岩石巨石上。总共记录了172个身高不超过5厘米的个体。水产养殖场或航运等人为活动可能是大型副千层虫进一步扩张的重要媒介或垫脚石。对该物种的额外记录增加了对其在地中海的生物地理分布、生物学和生态学的了解,并可能改善未来监测物种增殖和扩张的关键地理位置的选择。
