“…Of course, extensive analyses, beyond the confirmation of the automatic capture of perchers, are required for the practical application of the camera trap, as is feasible for mammals (e.g., Fukasawa et al, 2016 ; Nakashima, Fukasawa & Samejima, 2018 ). For ecological monitoring, data for spatial and temporal dynamics of population density at multiple locations are usually required for statistical analyses.…”

“…One potential method for monitoring dragonflies is the camera trap technique, a common approach for monitoring mammalian taxa. Commercial camera traps are relatively inexpensive have a high resolution and are easy to maintain owing to their low power consumption; it is only necessary to collect the digital records and change the batteries a few times a year ( Fukasawa et al, 2016 ; Yoshioka, Mishima & Fukasawa, 2016 ). However, these camera traps usually target homeotherms and are triggered by passive infrared sensors, such as a pyroelectric sensors, which are not usually applicable to insect detection.…”

Although dragonflies are excellent environmental indicators for monitoring terrestrial water ecosystems, automatic monitoring techniques using digital tools are limited. We designed a novel camera trapping system with an original dragonfly detector based on the hypothesis that perching dragonflies can be automatically detected using inexpensive and energy-saving photosensors built in a perch-like structure. A trial version of the camera trap was developed and evaluated in a case study targeting red dragonflies (Sympetrum spp.) in Japan. During an approximately 2-month period, the detector successfully detected Sympetrum dragonflies while using extremely low power consumption (less than 5 mW). Furthermore, a short-term field experiment using time-lapse cameras for validation at three locations indicated that the detection accuracy was sufficient for practical applications. The frequency of false positive detection ranged from 17 to 51 over an approximately 2-day period. The detection sensitivities were 0.67 and 1.0 at two locations, where a time-lapse camera confirmed that Sympetrum dragonflies perched on the trap more than once. However, the correspondence between the detection frequency by the camera trap and the abundance of Sympetrum dragonflies determined by field observations conducted in parallel was low when the dragonfly density was relatively high. Despite the potential for improvements in our camera trap and its application to the quantitative monitoring of dragonflies, the low cost and low power consumption of the detector make it a promising tool.

“…Because data papers can promote data sharing and provide several benefits to researchers, I recommend that Japanese ecologists publish original articles and data papers simultaneously (Osawa, ). Accordingly, my colleagues and I have published seven data papers (Fukasawa et al, ; Osawa, ; Osawa, Baba, et al, ; Osawa, Igehara, et al, ; Osawa, Kadoya, & Kohyama, ; Osawa & Wada, ; Osawa, Yamanaka, et al, ; Voraphab, Hanboonsong, Kobori, Ikeda, & Osawa, ) and several of these data papers were published simultaneously with corresponding original articles (Osawa, ; Osawa & Inohara, ; Osawa, Kohyama, et al, ; Osawa et al, ; Osawa, Yamanaka, et al, ). Here, a data paper should include all available data, not just the data used in the original article (Osawa, ).…”

Biodiversity informatics is the application of informatics techniques to ecology and biodiversity sciences. The premise is utilizing natural history collections/data, such as specimens and biodiversity observations, with information and communication technology. During the past two decades, biodiversity informatics has improved dramatically and has been applied increasingly in ecology science. In this paper, I review biodiversity informatics for ecology with a particular focus on the treatment of data. First, I discuss the traditional perspective of data collection and its usage in the ecological community. Then, I provide an overview of the trajectory of changing perspectives of data treatment relative to developing biodiversity informatics (i.e., the infiltration of the data reuse and sharing concepts). Specifically, I discuss the significance of data reuse, which offers numerous benefits for research, and data sharing with their supporting mechanisms and case studies. Finally, I discuss potential future developments in biodiversity informatics relative to the field of ecology.

“…This makes it possible to evaluate how habitat traits of organisms (i.e., typical habitat types inhabited by particular species) affect the relationship between land abandonment and species occurrence. Historically, abandoned settlements (or deserted villages) have emerged ubiquitously due to variety of causes such as economic environmental changes and disasters [15][16][17], and they offer us unique opportunities to evaluate long-term effect of land abandonment and recovery of ecosystems and to compare them among different climate. Species-specific sensitivity to land abandonment is determined by ecological traits [18,19] related to habitat preferences.…”

Land abandonment may decrease biodiversity but also provides an opportunity for rewilding. It is therefore necessary to identify areas that may benefit from traditional land management practices and those that may benefit from a lack of human intervention. In this study, we conducted comparative field surveys of butterfly occurrence in abandoned and inhabited settlements in 18 regions of diverse climatic zones in Japan to test the hypotheses that species-specific responses to land abandonment correlate with their climatic niches and habitat preferences. Hierarchical models that unified species occurrence and their habitat characteristics revealed that negative responses to land abandonment were associated with species having cold climatic niches utilizing open habitats, suggesting that traditional land use by human had long mitigated climate warming since the last glacier maximum through creating non-forest open habitats. Maps representing species gains and losses due to land abandonment, which were created from the model estimates, showed similar geographic patterns, but some parts of areas exhibited high species losses relative to gains. A hierarchical trait-based approach presented here revealed to be useful for scaling up local-scale effect of land abandonment to a macro-scale assessment, which is crucial to developing spatial conservation strategies in the era of depopulation.
