Two cases of probable hybridisation between the pufferfishes Arothron meleagris (Anonymous 1798) and A. nigropunctatus (Bloch and Schneider 1801) on a fringing reef at Réunion Island

Two individuals displaying mixed features of the colour patterns distinctive of Arothron meleagris and A. nigropunctatus were observed on the fringing reef at Réunion Island, between September 2012 and August 2013. Because many hybrid fish have been first identified through colour patterns that are intermediate between two known species, these pufferfish individuals were suspected to be hybrids. However, since no specimen was collected for examination, a hypothesis that the observed individuals could be hybrids is based on comparison of their colouration with colour patterns documented for A. meleagris and A. nigropunctatus. Several factors favouring hybridisation are met on this reef, particularly a difference in abundance between the two putative parental species. Since larval retention and self-recruitment are considered probable at Réunion, these individuals could be the progeny of interbreeding populations of these species on this reef. To our knowledge, only one hybrid has ever been reported in the genus Arothron, although without genetic confirmation. This implies that the existence of potentially interfertile species in this genus remains a hypothesis. Our field observations provide additional data supporting this hypothesis.     

中国真丝藻属Eudesme J.AG. (Chordariales, Phaeophyta)的研究

真丝藻属Eudesme是J.Agandh于1880年(J.Agardh 1880，p.29)建立的。其主要特征为：次生基部由直立初生中央轴及假根状丝体组成；初生中央轴由几个丝体束构成；假根状丝体则由中央丝体的基部产生；中央轴多管状，合轴分枝，由纵向排列的丝体组成，排列比较疏松；内皮层细胞从中央轴横向长出，稍网状排列；同化丝由内皮层末端细胞产生，不分枝，有密集的载色体；毛透明，从生长点或皮层丝体的基部产生；单室孢子囊无柄或在皮层丝体上有柄。 中国真丝藻，仅Lu Baoren和C.K. Tseng(1983)在“Common Seaweeds of China”中对Eudesme virescens(Cam.)J.Ag.作过描述外，未见其他更详细的报道。经过最近几年本文作者的研究发现中国真丝藻共有4种，除了Eudesme virescens(Cam.)J.Ag.外，另外还有黄海真丝藻Eudesme huanghaiensis Ding et Lu、青岛真丝藻 Eudesme qingdaoensis Ding et Lu和山东真丝藻Eudesme shandongensis Ding et Lu3种。
