一个基于个体的模型，MORPH，被用来评估英国普尔港的质量，为5个越冬的滨鸟：dunlin Calidris alpina，红脚鹬totanus，黑尾godwit Limosa limosa，牡蛎捕手Haematopus ostralegus和杓鹬Numenius arquata。场地质量和环境变化的影响，被测量为预测越冬生存。Dunlin有最高的猎物生物量密度，是最不可能受到影响的减少，他们的食物供应，较低的温度或陆地栖息地的损失黑尾godwits和杓鹬有最低的猎物生物量密度，是最有可能受到影响的减少，他们的食物供应，较低的温度和陆地栖息地的损失。所有五种滨鸟都受到模拟海平面上升的严重影响。为普尔港SPA确定的养护问题是较大体型多毛类蠕虫的密度相对较低，维护和管理周围陆地生境的重要性，以及海平面上升对潮间带食物供应时间长度的影响。(c)2006爱思唯尔有限公司保留所有权利。
An individuals-based model, MORPH, was used to assess the quality of Poole Harbour, UK, for five overwintering shorebirds: dunlin Calidris alpina, redshank Tringa totanus, black-tailed godwit Limosa limosa, oystercatcher Haematopus ostralegus and curlew Numenius arquata. Site quality, and the effect of environmental change, was measured as predicted overwinter survival. Dunlin had the highest prey biomass densities and were the least likely to be affected by reductions in their food supply, lower temperatures or loss of terrestrial habitats Black-tailed godwits and curlew had the lowest prey biomass densities and were the most likely to be affected by reductions in their food supply, lower temperatures and loss of terrestrial habitats. All five shorebird species were seriously affected by simulated sea-level rise. Conservation issues identified for the Poole Harbour SPA were the relatively low densities of larger size classes of polychaete worms, the importance of maintaining and managing surrounding terrestrial habitats and the effect of sea-level rise on the length of time for which intertidal food supplies are available.
