Evolution of larval competitiveness and associated life‐history traits in response to host shifts in a seed beetle

Fox C. W.; Messina F. J.

摘要

Abstract > Resource competition is frequently strong among parasites that feed within small discrete resource patches, such as seeds or fruits. The properties of a host can influence the behavioural, morphological and life‐history traits of associated parasites, including traits that mediate competition within the host. For seed parasites, host size may be an especially important determinant of competitive ability. Using the seed beetle, Callosobruchus maculatus , we performed replicated, reciprocal host shifts to examine the role of seed size in determining larval competitiveness and associated traits. Populations ancestrally associated with either a small host (mung bean) or a large one (cowpea) were switched to each other's host for 36 generations. Compared to control lines (those remaining on the ancestral host), lines switched from the small host to the large host evolved greater tolerance of co‐occurring larvae within seeds (indicated by an increase in the frequency of small seeds yielding two adults), smaller egg size and higher fecundity. Each change occurred in the direction predicted by the traits of populations already adapted to cowpea. However, we did not observe the expected decline in adult mass following the shift to the larger host. Moreover, lines switched from the large host (cowpea) to the small host (mung bean) did not evolve the predicted increase in larval competitiveness or egg size, but did exhibit the predicted increase in body mass. Our results thus provide mixed support for the hypothesis that host size determines the evolution of competition‐related traits of seed beetles. Evolutionary responses to the two host shifts were consistent among replicate lines, but the evolution of larval competition was asymmetric, with larval competitiveness evolving as predicted in one direction of host shift, but </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“main”XML：ID =“JEB13222-ABS-ABS-ABS-0001”XML：Lang =“EN”> <标题类型=“main”>抽象</ title> >资源竞争在寄生中经常强大饲料在小离散资源斑块，如种子或水果。宿主的性质可以影响相关寄生虫的行为，形态和生命历史特征，包括调解主体竞争的特征。对于种子寄生虫，宿主大小可能是竞争能力的特别重要的决定因素。使用种子甲虫， Callosobruchus maculatus </ i>，我们进行了复制，互惠宿主转移以检查种子大小在确定幼虫竞争力和相关性状时的作用。患有小主机（绿豆）或大型（豇豆）的人群被切换到彼此的主机36代。与控制线（剩余的祖先宿主中的那些）相比，从小宿主转换为大宿主的线在种子内发生了更大的幼虫（表明，通过增加两种成人的小种子的频率增加），更小鸡蛋大小和较高的繁殖力。每个变化发生在已经适应豇豆的人群的特征的方向上发生。但是，我们没有观察到转向较大的主持人后成人质量的预期下降。此外，从大型宿主（豇豆）切换到小型宿主（绿豆）的线并未演变在幼虫竞争力或鸡蛋大小的预测增加，但表现出预测的体重增加。因此，我们的结果为宿主尺寸决定了种子甲虫的竞争相关性状的演变的假设提供了混合支持。对两个宿主移位的进化反应在复制线中是一致的，但幼虫竞争的演变是不对称的，幼虫竞争力在宿主转移的一个方向上预测，但是 </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-34394/'>《Journal of evolutionary biology》</a> <b style="margin: 0 2px;">|</b><span>2018年第2期</span><b style="margin: 0 2px;">|</b><span>共12页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Fox C.
