Meanwhile, another semi-aquatic rodent, the Eurasian beaver (Castor fiber) is being restored to much of its native range including Great Britain. Beavers are known as ecosystem engineers and keystone species, creating wetland habitats. As part of the River Otter Beaver Trial in South-West England, free-living beavers were reintroduced in a location where water vole were present and being surveyed. Here, we present survey data showing the expansion of water vole into newly beaver engineered wetland areas. We propose that complex beaver wetlands may benefit water vole populations by creating new habitat and providing refuge from predation, warranting further investigation as a nature recovery option.","PeriodicalId":105794,"journal":{"name":"Mammal Communications","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116766706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These are notably higher than previous and current estimates of 5 - 33 hares/km2 (Matthews et al. 2018; Bedson et al. 2022). We review Hesford & MacLeod (2022) who based their methods on those used in a review of mountain hare survey methods in Scotland (Newey et al. 2018). This review demonstrated a weak, non-significant relationship between hare encounter rates using spotlight surveys of walked transects at night and estimated densities derived from spatial capture-recapture (SCR) methods on managed heather moorland (p=0.08). Newey et al. (2018) recommended that this relationship should not be used to estimate hare densities. We reproduce the Newey et al. (2018) linear model and confirm its poor predictive ability and show that removal of one outlier reduces an already marginal relationship to a near-flat line (p=0.80). Hesford & MacLeod (2022), nonetheless, used this relationship to estimate hare densities along non-randomly placed transects. We conclude that reportedly high mountain hare densities estimated by Hesford & MacLeod (2022) are biased and based on a model with little predictive power; more recent Distance Sampling estimates are from 37 - 96% lower (Bedson et al. 2022). It is important that wildlife monitoring methods robustly account for survey bias and error, detection probability and variation between habitats, especially if results are to inform potential population management interventions.","PeriodicalId":105794,"journal":{"name":"Mammal Communications","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124447350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although nest surveys have inherent errors, they remain the most easily accessible and cheapest method. The aim of this study was to count the number of nests found in consecutive years at two sites in southern England. We found that the harvest mouse nest densities fluctuated over time. This supports other studies that indicate harvest mice populations undergo major fluctuations from year to year. Although the drivers of this annual variation in nest numbers have not yet been identified, surveying for harvest mice using aerial nest counts in just one year could underestimate their likely presence at that site.","PeriodicalId":105794,"journal":{"name":"Mammal Communications","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122544253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast, closed-circuit television systems (CCTV) allow user choice of the system components and have comprehensive user-defined features. Portable CCTV systems are particularly useful to study species that can be difficult to monitor with trail cameras, such as bats, dormice, and otters. This paper describes portable CCTV systems and illustrates their use with particular respect to these species. The recent development of video content analytics in new CCTV systems dramatically increases the efficiency of video analysis, making CCTV a powerful tool for monitoring a wide range of wildlife.","PeriodicalId":105794,"journal":{"name":"Mammal Communications","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122629342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Counts of hauled out harbour and grey seals were conducted during aerial surveys and these have been scaled up to estimate population sizes. Most recent population estimates suggest ~900 harbour and ~3,200 grey seals reside in the Greater Thames Estuary. Both species have shown an upward population trend since surveys began in 2003. The wide distribution and growing number of seals across the Greater Thames Estuary over the last two decades shows the importance of this region for both species. It also highlights the value of long-term monitoring data to compliment seal surveys taking place elsewhere in the UK.","PeriodicalId":105794,"journal":{"name":"Mammal Communications","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126049116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
