虽然遥感图像在量化大面积土地覆盖变化方面是有效的，但其在直接评估动物对干扰的反应方面的效用有限。Soundscapes的方法-录音和分析的声音在一个sweet.ObjectivesIn 2011，一个巨大的野火命名为“马蹄2烧伤”发生在奇里卡瓦国家纪念碑，亚利桑那州，美国。我们评估了这场野火对动物群落的声学活动的影响。MethodsIn 2013年，音景录音收集了超过9个月的12个烧毁和12个非烧毁的网站在四个生态系统。季节性和昼夜生物声学活动进行了描述，使用“生物声学指数”，一个详细的听觉分析的声源，和一个新的工具，称为“声波Timelapse Builder”（STLB）。在六月的早晨，在四个生态系统中的三个中，燃烧的声音活动低于非燃烧的地点，这是由于树木死亡直接影响了蝉的数量减少。听觉分析显示，55%的录音从非烧伤网站包含昆虫的声音相比，18%从烧伤网站。在10月的夜晚，直翅目活动更普遍，在一些烧毁的网站，可能是由于火灾后出现的herbaceous.ConclusionsSoundscape方法可以帮助解决长期的保护问题，涉及动物群落野火的反应。声学方法可以作为一个有价值的补充，遥感干扰为基础的景观管理。
ContextWhile remote sensing imagery is effective for quantifying land cover changes across large areas, its utility for directly assessing the response of animals to disturbance is limited. Soundscapes approaches—the recording and analysis of sounds in a landscape—could address this shortcoming.ObjectivesIn 2011, a massive wildfire named “the Horseshoe 2 Burn” occurred in the Chiricahua National Monument, Arizona, USA. We evaluated the impact of this wildfire on acoustic activity of animal communities.MethodsIn 2013, soundscape recordings were collected over 9 months in 12 burned and 12 non-burned sites in four ecological systems. The seasonal and diel biological acoustic activity were described using the “Bioacoustic Index”, a detailed aural analysis of sound sources, and a new tool called “Sonic Timelapse Builder” (STLB).ResultsSeasonal biophony phenology showed a diurnal peak in June and a nocturnal peak in October in all ecological systems. On June mornings, acoustic activity was lower at burned than at non-burned sites in three of four ecological systems, due to a decreased abundance of cicadas directly impacted by the death of trees. Aural analyses revealed that 55% of recordings from non-burned sites contained insect sounds compared to 18% from burned sites. On October nights, orthopteran activity was more prevalent at some burned sites, possibly due to post-fire emergence of herbaceous.ConclusionsSoundscape approaches can help address long-term conservation issues involving the responses of animal communities to wildfire. Acoustic methods can serve as a valuable complement to remote sensing for disturbance-based landscape management.
