了解物种如何与农业景观相互作用，对于未来的保护工作至关重要。通过一个大规模的公民科学项目，我们对比农业领域的中心，研究了线状特征对蝙蝠活动的影响，并详细说明了不同类型的线状特征(密集管理的树篱、同情管理的树篱和树线)的影响。我们的结果表明，在调查中发现的所有10种蝙蝠种群都出现在田野中心以及沿线状特征。在进一步分析的五个物种组中，只有夜莺与农田中心相比不偏爱线性特征；然而，29%的铁马菊头蝠的叫声是在农田中心记录的。与其他线状特征类型相比，树线附近活跃的物种更多。我们的结果强调了线性特征管理对蝙蝠保护的重要性，但在调查设计和环境影响评估中也需要考虑野外中心1。蝙蝠是农业生态系统的重要组成部分。然而，与田野内部相比，人们对蝙蝠在农业环境中觅食和通勤时使用线性特征的程度知之甚少。2.作为一个大型公民科学项目的一部分，蝙蝠探测器被放置在农田(耕地和牧场)的中心和沿线特征(密集管理的树篱、同情管理的树篱和林线)。3.研究结果表明，所鉴定的10个蝙蝠种群均沿线状分布，并分布在农田中部。在进一步分析的五个物种组中，除了夜鹰外，所有物种沿着线形特征的蝙蝠活动都明显高于田野中间。然而，我们的结果显示，29%的铁头菊头蝠的叫声记录在农田的中间，相比之下，只有10%的尖头蝠叫声发生在农田的中部。与其他线性特征类型相比，BAT活动更有可能与树状线相关。4.我们的结果强调了线性特征管理对蝙蝠保护的重要性，但也强调了在调查设计和环境影响评估期间考虑实地中心的必要性。
Understanding how species interact with agricultural landscapes is essential for future conservation efforts. Using a large-scale citizen science project, we examined the influence linear features have on bat activity compared to the centre of agricultural fields and detailed the effect of different types of linear features (intensively managed hedgerows, sympathetically managed hedgerows and treelines). Our results showed that all 10 bat species groups identified during surveys occurred both in the centre of fields as well as along linear features. Out of the five species groups analysed further, only Nyctalus noctula had no preference for linear features, compared to the centre of agricultural fields; however, 29% of Rhinolophus ferrumequinum calls were recorded in the centre of fields. More species were active near treelines compared to other linear feature types. Our results highlight the importance of linear feature management to bat conservation, but also the need to consider field centres during survey design and Environmental Impact Assessments 1. Bats are important components of agricultural ecosystems. However, little is known about the extent to which bats use linear features when foraging and commuting in agricultural settings, when compared to the interior of fields. 2. As part of a large-scale citizen science project, bat detectors were placed in the centre of agricultural fields (arable and pasture) and along linear features (intensively managed hedgerows, sympathetically managed hedgerows and treelines). 3. Our results show that all 10 of the bat species groups identified were found both along linear features and in the middle of agricultural fields. Of the five species groups analysed further, all had significantly more bat activity along linear features compared to the middle of fields, except for Nyctalus noctula. However, our results showed that 29% of calls from Rhinolophus ferrumequinum were recorded in the middle of agricultural fields, compared to only 10% for Pipistrellus pipistrellus. Bat activity was more likely to be associated with treelines compared to other linear feature types. 4. Our results highlight the importance of linear feature management to bat conservation, but also the need to consider field centres during survey design and Environmental Impact Assessments.
