Abstract > <list formatted="paragraph" style="bulleted" xml:id="plb12613-list-0001"> <listItem> Changes in land‐use patterns are a major driver of global environmental change. Cessation of traditional land‐use practices has led to forest expansion and shifts in forest composition. Consequently, former monospecific forests maintained by traditional management are progressing towards mixed forests. However, knowledge is scarce on how the presence of other tree species will affect reproduction of formerly dominant species. We explored this question in the wind‐pollinated tree Juniperus thurifera . We hypothesised that the presence of heterospecific trees would have a negative effect on cone production and on the proportion of cones attacked by specialised predators. </listItem> <listItem> We assessed the relative importance of forest composition on cone production, seed development and pre‐dispersal cone damage on nine paired pure and mixed J.?thurifera forests in three regions across the Iberian Peninsula. The effects of forest composition on crop size, cone and seed characteristics, as well as damage by pre‐dispersal arthropods were tested using mixed models. </listItem> <listItem>Cone production was lower and seed abortion higher in mixed forests, suggesting higher pollination failure. In contrast, cone damage by arthropods was higher in pure forests, supporting the hypothesis that presence of non‐host plants reduces damage rates. However, the response of each arthropod to forest composition was species‐specific and the relative rates of cone damage varied depending on individual tree crops.</listItem> <listItem>Larger crop sizes in pure forests compensated for the higher cone damage rates, leading to a </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 =“PLB12613-ABS-0001”> <标题类型=“main”>抽象</ title> > <list格式=“段落”样式=“项目符号”XML：ID =“PLB12613-list-0001”> <listitem>土地使用模式的变化是全球环境变化的主要驱动因素。传统土地使用实践的停止导致森林扩张和森林成分转变。因此，传统管理维持的前一特异性森林正在朝着混合森林进展。然而，了解其他树种的存在如何影响以前的主要物种的繁殖的情况稀缺。我们在风授粉树中探讨了这个问题 juniperus thurifera </ i>。我们假设异质结构的存在会对锥体生产的负面影响以及专业捕食者攻击的锥体的比例。 </ listitem> <listitem>我们评估了森林成分对锥形生产，种子开发和患有九份的纯净和混合 j.?硫屈的森林的相对重要性伊比利亚半岛。使用混合模型测试森林成分对作物规模，锥形和种子特性的影响，以及通过预分散节肢动物损伤。 </ listitem> <listitem>锥形生产较低，种子流产在混合林中较高，表明授粉更高。相比之下，纯森林中节肢动物的锥体损伤较高，支持非宿主植物的存在降低了损伤率的假设。然而，每个节肢动物对森林成分的反应是特异性的，并且锥体损伤的相对速率根据个体树木作物而变化。</ listitem> <listitem>纯森林中的较大的作物尺寸补偿了较高的锥形损伤率，领先到A. </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-29390/'>《Plant biology》</a> <b style="margin: 0 2px;">|</b><span>2017年第6期</span><b style="margin: 0 2px;">|</b><span>共8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=Rodríguez‐García E.&option=202" target="_blank" rel="nofollow">Rodríguez‐García E.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Mezquida E.
