Comprehensively detailed information on population dynamics for benthic species is crucial since potential admixture of individuals could shift the genetic subdivision and age structure during a full breeding period. The apparent genetic impact of the potential recruitment strategy of Norway lobster Nephrops norvegicus is still under research. For this reason the present study was focused on genetic variation of the species over a given continuous year period in a semi-enclosed gulf of the Aegean Sea. Analyses revealed that the relative smaller size class in females and the apparent faster growth of males may represent a key-role differential strategy for the two sexes, whereas females tend to mature slower. Heterozygosity fitness correlations (HFCs) showed substantially significant associations suggesting that inbreeding depression for females and outbreeding depression for males are the proximate fitness mechanisms, respectively. Nephrops norvegicus uniformal genetic composition (background of high gene flow), could be attributed to potential population recolonization, due to a hypothesized passive larval movement from deeper waters, which may suggest that some offspring of local residents and potential male non-breeders from other regions admixture randomly.

地中海东部爱琴海中挪威龙虾的杂合度适应度相关性和世代间隔

有关底栖物种种群动态的全面详细信息至关重要，因为个体的潜在混合可能会在整个繁殖期间改变遗传细分和年龄结构。挪威龙虾Nephrops norvegicus潜在招募策略的明显遗传影响仍在研究中。因此，本研究的重点是在一个给定的连续年中，在一个半封闭的爱琴海海湾中，该物种的遗传变异。分析表明，雌性个体相对较小，雄性表观生长较快，可能代表了两种性别的关键角色差异化策略，而雌性则趋于成熟。杂合度适应性相关性（HFC）显示出显着的相关性，提示女性近交抑郁和男性近交抑郁分别是最接近的适应机制。Nephrops norvegicus的统一遗传组成（高基因流量的背景），可能归因于潜在的种群重新定殖，原因是推测的来自较深水域的被动幼虫运动，这可能表明当地居民的某些后代以及其他地区的潜在男性非繁殖者随机混合。
