Adaptations solitary wasp populations dynamic

项目摘要

Dynamic environments in which the availability of resources fluctuate frequently and habitat can become fragmented over short timescales provide extreme challenges for the organisms inhabiting them. In these environments, populations of organisms may be geographically structured in ways such that the extinction of small, local populations is not catastrophic for the global population as a whole. One such structure is defined by Levins' metapopulation concept, in which local extinctions and recolonisations are balanced to prevent overall extinction. Hymenoptera, the insect order comprising bees, wasps, and ants, is thought to be the most speciose on the planet, occupying a variety of environmental conditions and exhibiting myriad life history strategies. Solitary wasps are essential for the functioning of ecosystems through processes including predation, pollination, and seed dispersal, yet remain largely understudied. Blakeney Point, on the coast of Norfolk in the UK, provides an ideal location for the study of solitary wasps in a dynamic coastal environment. This project will explore whether such species in challenging conditions live in a metapopulation structure, and identify behavioural and genomic adaptations to the landscape, with important implications for our understanding of other organisms inhabiting fragmented landscapes and providing much-needed knowledge on understudied taxa.

在动态环境中，资源的可获得性经常波动，栖息地可能在短时间内变得支离破碎，这给栖息在其中的有机体带来了极端的挑战。在这些环境中，生物种群的地理结构可能会使当地小种群的灭绝对全球种群作为一个整体来说不是灾难性的。莱文斯的集合种群概念定义了一种这样的结构，即在局部灭绝和重新殖民之间取得平衡，以防止整体灭绝。膜翅目是由蜜蜂、黄蜂和蚂蚁组成的昆虫目，被认为是地球上最特殊的昆虫，占据了各种环境条件，展示了无数的生活史策略。独居黄蜂通过捕食、授粉和种子传播等过程对生态系统的功能至关重要，但在很大程度上仍未得到充分研究。布莱克尼角位于英国诺福克海岸，为在动态的沿海环境中研究独居黄蜂提供了理想的位置。这个项目将探索这些物种在具有挑战性的条件下是否生活在集合种群结构中，并确定行为和基因组对景观的适应，这对我们理解生活在零散景观中的其他生物具有重要意义，并提供关于未被研究的类群的急需的知识。
