PY - 2012 DA - 2012/05/08 TI - Exploring Relationships between Demersal Resources and Environmental Factors in the Ionian Sea (Central Mediterranean) SP - 279406 VL - 2012 AB - The relationships between the abundance of demersal resources, environmental variables, and fishing pressure in the north-western Ionian Sea in the last two decades were evaluated. Data on the density collected during seventeen trawl surveys carried out from 1985 to 2005 were used. The following species were considered: aristaeomorpha foliacea，诺弗里布诺威奇，和 Parapenaeus longirostris.对于甲壳类动物; Merluccius Merluccius，Phycis Blennoides，和 mullus barbatus.对于远程鱼鱼。还考虑了招聘指数 N. norvegicus，P. longirostris，M. Merluccius和 mullus barbatus.。为每个密度和招聘数据进行评估六种候选模型，这些模型将捕捞努力与全球（NAO）和区域（SST和降水）的气候指数相结合，或分别涉及捕捞努力，NAO或区域气候指数作为唯一预测变量的模型。使用应用Akaike的信息标准（AIC）的信息理论方法进行模型选择。对于每个物种的密度数据和招聘指标，观察到随时间的高变化。除了欲望丰富和招聘数据之外，检测到与Nao指数的明显阳性关系，其他物种观察到的变化似乎是与物理环境和顶部变化相关的自下而上效应之间的相互作用的结果- 由于钓鱼压力，朝内。SN - 2633-4666 UR - https://doi.org/10.1155/2012/279406 do - 10.1155 / 2012/279406 JF - 海洋生物学PB - Hindwi Publishing Corporation KW - ER -
