MCR LTER: Coral Reef: Habitat Utilization and Pairing Patterns of Mutualistic Shrimps and Gobies from 7 Indo-Pacific regions

We analyzed network level specialization for eight Indo-Pacific networks of
obligate, mutualistic gobies and shrimps, and elucidated ecological and evolutionary
factors driving specialization. To accomplish this we collected and analyzed data on
species pairings in Moorea, French Polynesia (lat. -17.49, long. -149.84), Kenting,
Taiwan (lat. 21.95, long. 120.76), and Kimbe Bay, New Britain, Papua New Guinea
(PNG; lat. -5.50, long. 150.12), and combined these observations with previously
published data from Seychelles Islands (Polunin and Lubbock 1977), Great Barrier
Reef, Australia (Cummins 1979), Red Sea, Israel (Karplus et al. 1981), Japan
(Yanagisawa 1984), and the Gulf of Thailand, Thailand (Nakasone and Manthachitra
1986). We also systematically collected and analyzed habitat data for shrimps and
gobies in Moorea, Taiwan, and PNG. We found specialization was affected by
variability in habitat use for both gobies and shrimps and by phylogenetic history
for shrimps. Habitat use was phylogenetically conserved among shrimp, and thus
effects of shrimp phylogeny on partner choice were mediated in part by habitat. By
contrast, habitat use and pairing patterns in gobies were not related to
phylogenetic history. This asymmetry appears to result from evolutionary constraints
on partner use in shrimps and convergence among distantly-related gobies to utilize
burrows provided by multiple shrimp species. Results indicate that the evolution of
mutualism is affected by life history characteristics that transcend environments
and that different factors constrain interactions in disparate ecosystems. These data are associated with this publication: Thompson AR, Adam TC, Hultgren KM, Thacker CE (in press).

本研究针对印太海域8组专性互利虾虎鱼与虾的共生网络，开展了网络水平特化分析，并阐明了驱动该特化现象的生态与进化因子。
为完成该研究目标，我们采集并分析了法属波利尼西亚茉莉雅岛（纬度-17.49，经度-149.84）、中国台湾垦丁（纬度21.95，经度120.76）以及巴布亚新几内亚新不列颠岛金贝湾（PNG；纬度-5.50，经度150.12）三地的物种互作配对数据，并将这些观测结果与已发表的历史数据集整合，涵盖塞舌尔群岛（Polunin与Lubbock，1977）、澳大利亚大堡礁（Cummins，1979）、以色列红海海域（Karplus等，1981）、日本（Yanagisawa，1984）以及泰国泰国湾（Nakasone与Manthachitra，1986）的相关研究数据。
此外，我们还系统采集并分析了茉莉雅岛、中国台湾及巴布亚新几内亚三地虾虎鱼与虾的栖息地数据。
研究发现，虾虎鱼与虾的栖息地利用差异，以及虾的系统发育历史，均会影响物种互作特化程度。
虾的栖息地利用具有系统发育保守性，因此虾的系统发育对伴侣选择的影响，部分通过栖息地特征介导。
与之形成对比的是，虾虎鱼的栖息地利用与配对模式均与系统发育历史无关。
这种不对称性推测源于虾在伴侣选择上的进化约束，以及远缘虾虎鱼类群间趋同演化出利用多种虾类所掘洞穴的策略。
研究结果表明，互利共生的演化受跨环境的生活史特征调控，且不同生态系统中物种互作所受的约束因子存在差异。
