“…We calculated relative abundance index (RAI) for each species in each study site as the number of independent photographs or videos per 100 camera trap-nights (Carbone et al 2001). Consecutive photos or videos of the same taxon captured <30 minutes apart were considered as a single independent event (Chen et al 2022;Nottingham et al 2021).…”

Background: Traditional wildlife monitoring has often relied on invasive techniques posing risks to species and demanding substantial resources. To address this, camera traps emerged as non-invasive alternatives, albeit primarily tailored for larger mammals, posing limitations for small mammal research. Thus, the Mostela, an innovative tool designed to overcome these challenges, was introduced to monitor small mammals in South Korea. Results: The Mostela was deployed at two study sites in South Korea, yielding compelling evidence of its efficiency in capturing small mammal species. By analyzing the collected data, we calculated the relative abundance of each species and elucidated their activity patterns. Conclusions: In summary, the Mostela system demonstrates substantial potential for advancing small mammal monitoring, offering valuable insights into diversity, community dynamics, activity patterns, and habitat preferences. Its application extends to the detection of endangered and rare species, further contributing to wildlife conservation efforts in South Korea. Consequently, the Mostela system stands as a valuable addition to the toolkit of conservationists and researchers, fostering ethical and non-invasive research practices while advancing our understanding of small mammal populations and ecosystems.

“…Camera traps (also known as trail cameras) and other remote stationary cameras have also been used to great effect in detecting and monitoring the abundance of mammals [e.g. in New Zealand (Anton, Hartley & Wittmer, 2018; Nottingham, Glen & Stanley, 2021)]. Imagery collected by UAVs, camera traps, and other remote automated photographic technology can be combined with machine‐learning and artificial intelligence algorithms to automate monitoring across broad areas (e.g.…”

A framework to integrate innovations in invasion science for proactive management

Invasive alien species (IAS) are a rising threat to biodiversity, national security, and regional economies, with impacts in the hundreds of billions of U.S. dollars annually. Proactive or predictive approaches guided by scientific knowledge are essential to keeping pace with growing impacts of invasions under climate change. Although the rapid development of diverse technologies and approaches has produced tools with the potential to greatly accelerate invasion research and management, innovation has far outpaced implementation and coordination. Technological and methodological syntheses are urgently needed to close the growing implementation gap and facilitate interdisciplinary collaboration and synergy among evolving disciplines. A broad review is necessary to demonstrate the utility and relevance of work in diverse fields to generate actionable science for the ongoing invasion crisis. Here, we review such advances in relevant fields including remote sensing, epidemiology, big data analytics, environmental DNA (eDNA) sampling, genomics, and others, and present a generalized framework for distilling existing and emerging data into products for proactive IAS research and management. This integrated workflow provides a pathway for scientists and practitioners in diverse disciplines to contribute to applied invasion biology in a coordinated, synergistic, and scalable manner.

“…The e cacy of rodent monitoring methods in different management scenarios therefore warrants careful assessment. Some of the most commonly used devices to monitor the presence of rodents include motion-triggered camera traps, chew cards, and tracking tunnels (Shiels et al 2018;Nottingham et al 2021). There are distinct bene ts and challenges with the use of each of these devices as rodent monitoring tools.…”

Accurate detection of invasive rodents is essential to guide appropriate management responses, including effective control. Due to the arboreal behaviour of some invasive rodent species, above-ground monitoring may provide managers with a clearer picture of rodent presence. Numerous ground-based rodent monitoring tools have been tested and compared, but how these tools perform in an arboreal context is unknown. Our study sought to compare the strata-specific detection capability of three widely applied rodent monitoring tools using a nested design. Over two month-long periods, we deployed 180 monitoring stations at the ground, mid-storey and canopy across 30 forested sites. Each monitoring station consisted of a camera trap, chew card and tracking tunnel positioned to detect rodent presence. Device agreement was high, with all devices detecting rodent presence at 50% of stations. Chew cards were the most sensitive above-ground tool, implied by positive rodent detection 90% of the time, while tracking tunnels and camera traps generated a positive detection 74% and 75% of the time respectively. Low equipment costs also made chew cards the most cost-effective method. Detection performance differed according to the strata in which the device was deployed, thus a combination of methods that includes camera traps and chew cards was most effective when implementing a three-dimensional rodent monitoring network in forested settings. While not all methods are equal, traditionally ground-based rodent monitoring devices can be used to effectively monitor arboreal rodent activity. We provide evidence-based guidance for invasive rodent monitoring in an arboreal context to support future invasive rodent population control or eradication programs.
