Pitfall trapping is among the most widely used sampling methods for ground‐dwelling beetles. However, the sampled ground‐dwelling beetle abundance in pitfall traps may be biased, which can lead to difficulties when comparing the sampled abundance between different habitats.To better understand the comparability of the sampled abundance, we focused on two sampling processes: a temporary migration process (referring to the individual movements into and out of the effective trap area) and a removal process (determining the number of individuals collected given the number of individuals within the trap area).To examine the effects of the temporary migration process, we compared the sampled abundance of 10 ground‐dwelling beetle species inside and outside enclosures in 2 habitats (clear‐cut and forested sites) and found that installing the enclosure decreased the sampled abundance in both habitats, but the effects did not differ among habitats.To examine the effects of the removal process, we examined the effects of daily soil temperature on the daily sampled abundance (removal probability) of Pterostichus thunbergi using removal sampling within enclosures. We found that soil temperature increased the removal probability, but this effect was limited and not consistent across survey periods.The results suggest that the effects of the temporary migration process may not be habitat dependent and that the effects of the removal process may be small. Therefore, the traditional use of pitfall traps is, to some extent, a robust and comparable measure of the sampled abundance of ground‐dwelling beetles among different habitats.

Abstract Background Globally, mental health promotion related to psychological distress in the workplace has become a great concern, and a focus of much research attention. However, a sense of contribution to society and sense of bonding with the workplace have not been examined in relation to psychological distress. Thus, the purpose of this study is to examine whether these two factors are associated with psychological distress. Methods We conducted a cross-sectional survey of 1137 full-time employees who worked in systems engineering, sales, or administration at a Japanese company. Participant's sense of contribution to society, sense of bonding with the workplace, psychological distress, and qualitative job stress (quantitative and qualitative workloads, job-control latitude, and support from supervisors, co-workers and family) were assessed with a questionnaire. We performed multiple logistic regression analyses to examine associations between psychological distress and sense of contribution to society and of bonding with the workplace. Results A high sense of contribution to society was significantly associated with a high sense of bonding with the workplace (Spearman's ρ = 0.47, p < 0.01). A sense of contribution to society was negatively associated with psychological distress after adjusting for job stress factors (OR = 2.05, 95% CI 0.99-4.23) or sociodemographic characteristics of participants (OR = 2.92, 1.53-5.59). After adjusting for job stress factors as well as sociodemographic characteristics, the association became weaker. A sense of bonding with the workplace was negatively associated with psychological distress after adjusting for sociodemographic characteristics (OR = 2.49, 1.29-4.79). However, this association was not observed after adjusting for job stress factors. Conclusions Psychological distress in the workplace was associated with sense of contribution to society. Therefore, workplace mental health promotion should consider the workers' sense of contribution to society.

Landscape-scale habitat selection of breeding goshawks and creation of a habitat model of goshawk landscape use in an area that contained forested, agricultural and urban landscapes in northern Japan are discussed. Results suggest that management efforts should focus on maintaining landscapes that side prey availability and connectivity between forest patches and on preventing urbanization over entire home ranges.
