Description
The FishMed database provides traits, phylogeny, current and projected species distribution of Mediterranean fishes, and associated SST from the regional oceanic model NEMOMED8. Data for the current geographical distributions of 635 Mediterranean fish species were compiled from a published expert knowledge atlas of fishes of the northern Atlantic and the Mediterranean (FNAM) edited between 1984 and 1986 and from an updated exotic fish species list. Two future sets of projected species distributions were obtained for the middle and end of the 21st century by using an ensemble forecasting approach for 288 coastal Mediterranean fish species based on SST according to the IPPC/SRES A2 scenario implemented with the Mediterranean climatic model NEMOMED8. The functional part of the database encompasses 12 biological and ecological traits (maximal and common lengths, vertical distribution, habitat, migration type, mode of reproduction, sex shift, semelparity, diet type (larvae and adults), social behavior, species origin and depth) for the 635 fish species. To build the phylogeny we inferred the timing and geographic origins of Mediterranean teleost species diversity using nucleotide sequences collected from GenBank including 62% of Mediterranean teleost species plus nine outgroups. Maximum likelihood Bayesian phylogenetic and dating analyses were calibrated using 20 fossil species. An additional 124 fish species were grafted onto the chronogram according to their taxonomic affinity to obtain a phylogenetic tree including 498 species. Finally we also present the associated SST data for the observed period (1961–1980) and for the middle (2040–2059) and the end of the 21st century (2080–2099) obtained from NEMOMED8 according to the IPCC A2 scenario. The FishMed database might be of interest in the context of global anthropogenic changes as coastal Mediterranean ecosystems are currently recognized as one of the most impacted ecosystems on earth.

Key words: climate change; coastal fishes; functional diversity; Mediterranean fish species; Mediterranean Sea; NEMOMED8, species distribution models; phylogenetic diversity; taxonomic diversity.

数据集描述
FishMed数据库提供地中海鱼类的功能性状、系统发育信息、当前及预测的物种分布数据，以及来自区域海洋模型NEMOMED8的配套海表温度（Sea Surface Temperature, SST）数据。
针对635种地中海鱼类的当前地理分布数据，本数据集整合自1984至1986年间编制的《北大西洋及地中海鱼类专家知识图集》（FNAM），以及一份更新后的外来鱼类物种名录。研究基于海表温度数据，借助地中海气候模型NEMOMED8实现的IPPC/SRES A2排放情景，通过集合预报方法针对288种地中海沿岸鱼类，生成了21世纪中期及末期的两套预测物种分布数据。
本数据库的功能性状模块涵盖全部635种鱼类的12项生物学及生态学性状，包括最大体长、常见体长、垂直分布范围、栖息生境、洄游类型、繁殖方式、性逆转特性、单次生殖特性、食性类型（幼体及成体）、社会行为、物种起源及栖息深度。
为构建系统发育树，研究团队利用从GenBank获取的核苷酸序列，推断了地中海硬骨鱼类物种多样性的演化时间及地理起源，所使用的序列覆盖62%的地中海硬骨鱼类类群，外加9个外类群。研究通过20个化石物种对最大似然法贝叶斯系统发育及年代测定分析进行了校准，随后依据分类学亲缘关系将额外的124种鱼类接入该时间树，最终得到包含498个物种的系统发育树。
最后，本数据集还提供了基于NEMOMED8模型、依照IPCC A2排放情景生成的配套海表温度数据，涵盖观测时段（1961–1980年）以及21世纪中期（2040–2059年）和末期（2080–2099年）。
鉴于地中海沿岸生态系统目前被认为是全球受人类活动影响最显著的生态系统之一，FishMed数据库可为全球人为活动驱动的气候变化相关研究提供重要支撑。
