“…Our approximate 6-7 m of location error was at the lower end of that range and closely approached the suggested distance of 5 m to maintain accuracy given our study area size (60.7 ha) and relative patch sizes (~ 5-10 ha) [46]. Current in-depth resource selection studies of small mammals using micro-VHF devices are limited and even fewer have detailed telemetry error assessments [1,15,17,23,31,32,76]. Therefore, it was difficult to gauge what distance would create an impactful bias in a small mammal study.…”

“…Generally, the two common tracking technologies to gather needed terrestrial locational data are very high frequency (VHF) and Global Positioning System (GPS) trackers [7][8][9][10][11][12][13][14]. The newer, more advanced GPS trackers are efficient and accurate for medium and large mammals, and there have been some recent studies using smaller GPS trackers for smaller medium-sized mammals, like feral cats or hares [15][16][17]. As technology increases, we expect to see future increasing effectiveness, but GPS technology for very small mammals is still significantly limited because of collar weight or the inability to produce a recordable signal [7,8,12,15,16,[18][19][20][21][22][23][24].…”

Background Fine-scale tracking of animals such as Peromyscus spp. is still done with micro-very high frequency collars due to the animal’s small size and habitat usage. In most cases, tracking micro-very high frequency collars requires manual telemetry, yet throughout the literature, there is little reporting of individual telemetry methods or error reporting for small mammal spatial analyses. Unfortunately, there is even less documentation and consensus on the best programs used to calculate fine-scale animal locations from compass azimuths. In this study, we present a strategy for collecting fine-scale spatial data on Peromyscus spp. as a model species for micro-very high frequency collars and assess multiple programmatic options and issues when calculating telemetry locations. Results Mice were trapped from April to October 2018–2019 with Sherman traps in Howard County, Maryland, USA. Collars were placed on 61 mice, of which 31 were included in the analyses. We compared the two most cited location estimator programs in the literature, location of a signal software and Locate III, as well as the Sigloc package in program R. To assess the programmatic estimates of coordinates at a fine scale and examine programmatic impacts on different analyses, we created and compared minimum convex polygon and kernel density estimator home ranges from locations produced by each program. We found that 95% minimum convex polygon home range size significantly differed across all programs. However, we found more similarities in estimates across calculations of core home ranges. Kernel density estimator home ranges had similar patterns as the minimum convex polygon home ranges with significant differences in home range size for 95% and 50% contours. These differences likely resulted from different inclusion requirements of bearings for each program. Conclusions This study highlights how different location estimator programs could change the results of a small mammal study and emphasizes the need to calculate telemetry error and meticulously document the specific inputs and settings of the location estimator.

“…Based on these results, we do not recommend that farm owners keep cats as one of the rodent control measures. It was reported that cats traveled an average of 3.8 km, with a maximum of 6.3 km, from the inhabited farm (Ferreira et al 2011), although the home range can vary depending on many factors (Nottingham et al 2022). Therefore, when farm owners keep cats, the cats can cause problems on livestock farms within this range.…”

One of the obstacles to controlling rodents on livestock farms in Japan is the lack of information about characteristics that lead to infestations. To address this knowledge gap, we performed a nationwide survey that collected information from livestock farmers, including the types and number of livestock present, severity of rodent infestation, rodent management approaches utilized, and details about the most- and least-infested barns. More than 80% of respondents reported rodent infestation on their farms, especially rodents observed on overhead beams and girders. A multiple ordinal logistic regression analysis revealed that the odds ratio of rodent infestation was higher on farms housing pigs and lower on farms with chickens, as compared to farms with cattle. We also found that medium-sized farms, but not large-sized farms, showed a higher odds ratio than small-sized farms. Furthermore, the odds ratio was similarly higher on farms that implemented rodent control measures by themselves or with the assistance of pest control operators, compared to farms with no rodent management. Within a farm, barn age contributed to infestation status, such that the most-infested barns were older than the least-infested barns, regardless of livestock species. Furthermore, the proportion of ad libitum feeding was higher in the most-infested barns than in the least-infested barns on pig farms. Taken together, our results provide valuable information for understanding rodent infestations on livestock farms in Japan, which can contribute to the development of better management approaches.

“…More data on feral cat habitat use (e.g., Nottingham et al, 2022;Rodriguez-Recio et al, 2022), particularly following controls, are needed to better understand our results. In particular, to which extent the pattern of cat abundance reported in controlled and uncontrolled zones in Sessions 2 and 3 may have been triggered by a recolonization of controlled zones from uncontrolled zones following an important amount of cats removed during the second control deserves further investigation.…”

Invasive alien species are a major threat to seabird species, and the number of impacted species is still increasing. A recent study revealed for the first time that feral cats predated a large albatross species and that without cat control, some albatross populations would markedly decline. We examined this new predator–prey system by individually monitoring known‐age wandering albatross chicks with camera traps in a colony experimentally divided into zones with and without cat control. Our design allowed us to investigate how cat control influenced cat abundance and how this in turn influenced the probability for a chick to be predated by a cat. After cat controls, cat abundance was lower in controlled zones than in uncontrolled zones, while a survival analysis showed that the probability for a chick to die from cat predation depended on the zone but not on cat abundance. Our monitoring also provided a fine‐scale investigation of the various sources of chick mortality. In addition to cat predation (24% of mortality overall), our data documented predation by giant petrels, for the first time in Kerguelen, and revealed a strong and unexpected effect of nest flooding on chick mortality. Overall, our results underline the need for future studies investigating interindividual variability in cat diet and spatial ecology.
