“…However, previous studies have also shown that the mortality rate is not necessarily higher in pitfall traps compared to Sherman traps (Barros et al 2015), because we can reduce the mortality rate of animals in pitfall traps by taking some precautionary measures, such as drilling small holes at the bottom of buckets to prevent water accumulation, adding bucket lids to protect animals from exposure to the sun and rain, adding food in the buckets to avoid starvation, and so on. Snap traps are mainly used for pest rodent control and monitoring the population dynamics of small mammals (Taulman et al 1992;Lane et al 2010;Hobbs & Brehme 2017).…”

It is challenging to reveal the real-time spatio-temporal change of diversity and abundance of animals in natural systems by using traditional methods. The rapid advancement of new technologies such as the Internet of Things, artificial intelligence, and big-data processing, provide opportunities for developing novel technologies for monitoring biodiversity and population abundance of animals with high efficacy and accuracy. In this study, by using a recently developed Intelligent Animal Monitoring System, named "Vector Intelligent Monitoring System (VIMS)", we investigated the real-time diversity and abundance of small mammals in the Banruosi forest, Dujiangyan region, southwest China. To make a comparison of the VIMS with traditional methods, we also surveyed the diversity and abundance of small mammals using wired live traps. Compared to live traps, the VIMS has several advantages such as automatic data collection, intelligent identification of species, data visualization, whole-day and all-weather operation, little disturbance to animals, real-time monitoring, and is capable of revealing more small mammal species. However, the VIMS also has several disadvantages over live traps such as lower trapping efficiency and being more expensive than live traps. Our results suggest that the VIMS can be a complementary method to traditional ones in monitoring the real-time spatio-temporal change of diversity and abundance of small mammals (especially rare species). In addition, the VIMS is useful in monitoring other small animals like small carnivores, birds, amphibians, and reptiles.

“…Despite being commensal with humans, house mice commonly occur at low densities in managed forests of the southeastern United States (Mitchell et al , Iglay , Lane et al ). In fall 2009 (year 1), we observed house mice immigrating across all treatment types into the research site from adjacent, recently harvested agricultural fields (Marshall et al ; Fig.…”

Rodent population and community responses to forest-based biofuel production

Intensively managed forests in the southeastern United States are a potential source of cellulosic bioenergy and, as conversion technologies improve and demand increases, a greater land area may be required to produce biofuel feedstocks. However, responses of wildlife to forest-based biofuel production are largely unknown. We examined the 4-year response of rodent populations and assemblages to a range of biofuel production regimes, including harvesting residual woody debris and intercropping switchgrass (Panicum virgatum), in an intensively managed loblolly pine (Pinus taeda) forest in eastern North Carolina, USA. We investigated abundance, demography, and community response of rodents in a randomized and replicated field experiment using mark-recapture techniques during 2009-2012. Whereas removal of downed woody biomass did not affect abundance, diversity, or demography of rodents, we detected species-specific effects of incorporating switchgrass. After switchgrass was well established, invasive house mice (Mus musculus) were most abundant in plots with switchgrass. In contrast, white-footed mice (Peromyscus leucopus) were commonly captured in plots without switchgrass and other rodents were not affected by biofuel treatments. Across the study, natural succession exerted greater effects on rodent species and the rodent community than biofuel production regimes. As remaining logs and stumps decay and become limiting, downed wood may become more important to rodents. Our results indicate that intercropping switchgrass and harvesting residual woody material had limited effects on rodents in the Coastal Plain of North Carolina, USA within 4 years of stand establishment.
