【摘 要】
：
2016年10月采自北部湾海域的1尾鱼类标本经鉴定为线鳍鲆属Taeniopsetta Gilbert,1905的眼斑线鳍鲆Taeniopsetta ocellata(Günther,1880),隶属于鲽形目Pleuronectiformes鲆科Bothidae,这是该属和种首次在中国大陆海域的报道.线鳍鲆属的主要形态特征包括:体长卵圆形;双眼位于头左侧;口小;有眼侧和无眼侧均有1行小尖牙;鳞细小,仅体左侧有1条侧线;雄鱼有1枚强吻棘和2或3枚眼棘,雌鱼吻棘和眼棘很钝或无;无眼侧腹鳍始于有眼侧第2根腹鳍鳍条

“新时期粤港澳大湾区协同发展”专刊序言
区域协同发展是新时期粤港澳大湾区提升国际竞争力、建设国际一流湾区和世界级城市群的关键,也是一项与时俱进的科学议题.之所以讲“与时俱进”,是因为,协同发展对于粤港澳大湾区(或者说大珠三角城市群)并非一个新的话题.上世纪80年代以来,众多人文地理学者围绕粤港澳区域合作、区域联动和一体化发展等议题展开了大量卓有成效的研究,揭示了粤港之间“前店后厂”的区域协同模式.“前店后厂”作为标志性的模式,深入地揭示了改革开放以来粤港澳协同发展的内涵,也获得了学术界的广泛认同.然而近20年来随着合作模式的全方位推进,今天已很
