“…This buffer distance is the approximate radius of circle of 3.5 ha, which is the estimate of home‐range size (kernel estimator) for rice rats provided by Cooney et al. () for the mining site. In addition to the land cover variables, we included the area encompassed within the 100‐m buffer around each patch to provide a surrogate for patch size of the wetland.…”

Variation in metapopulation dynamics of a wetland mammal: The effect of hydrology

Key factors affecting metapopulation dynamics of animals include patch size, isolation, and patch quality. For wetland‐associated species, hydrology can affect patch availability, connectivity, and potentially habitat quality; and therefore drive metapopulation dynamics. Wetlands occurring on natural river floodplains typically have more dynamic hydrology than anthropogenic wetlands. Our overall objective was to assess the multiyear spatial and temporal variation in occupancy and turnover rates of a semi‐aquatic small mammal at two hydrologically distinct wetland complexes. We live‐trapped marsh rice rats (Oryzomys palustris) for 3 yr and >50 000 trap nights at nine wetland patches on the Mississippi River floodplain and 14 patches at a reclaimed surface mine in southern Illinois. We used dynamic occupancy modeling to estimate initial occupancy, detection, colonization, and extinction rates at each complex. Catch per unit effort (rice rats captured/1000 trap nights) was markedly higher at the floodplain site (28.1) than the mining site (8.1). We found no evidence that temperature, rainfall, or trapping effort affected detection probability. Probability of initial occupancy was similar between sites and positively related to patch size. Patch colonization probability at both sites was related negatively to total rainfall 3 weeks prior to trapping, and varied across years differently at each site. We found interacting effects of site and rainfall on extinction probability: extinction increased with total rainfall 3 months prior to trapping but markedly more at the floodplain site than at the mining site. These site‐specific patterns of colonization and extinction are consistent with the rice rat metapopulation in the floodplain exhibiting a habitat‐tracking dynamic (occupancy dynamics driven by fluctuating quality), whereas the mineland complex behaved more as a classic metapopulation (stochastic colonization & extinction). Our study supports previous work demonstrating metapopulation dynamics in wetland systems being driven by changes in patch quality (via hydrology) rather than solely area and isolation.

“…Their abilities to cross more than 300 m of water (Smith and Vrieze , Forys and Dueser ) and to move ~400 m daily (Cooney et al. ) increase their dispersal potential, which in turn increases gene flow among distinct populations (Loxterman et al. ).…”

“…In deer mice [Peromyscus maniculatus (Wagner, 1845)], for example, the home range was smaller in areas when food was available, whereas in areas of poor food quality, it was larger. In addition, many small mammals expand their home ranges in the summer when food is in scarcity, also coinciding with mating and recruitment (Cooney et al 2015).…”

“…The densities of Mastomys are usually higher at disturbed areas, e.g. agricultural fields than in natural environments (Monadjem and Perrin 2003, Massawe et al 2007, Mohr et al 2007 where the animals expand their home range (Cooney et al 2015) and alter their sex ratio (Gomez et al 2008).…”

Home ranges, sex ratio and recruitment of the multimammate rat (Mastomys natalensis) in semi-arid areas in Tanzania

et al. 2019

Investigation of home ranges, sex ratio and recruitment of the multimammate rat (Mastomys natalensis) in semi-arid areas of Tanzania was conducted in maize and fallow fields using the capture-mark-release (CMR) technique. The aim of this study was to generate useful data for the management of M. natalensis. The relative home range size of M. natalensis was significantly higher during the wet [544 m2 ± 25 standard error (SE)] than during the dry (447 m2 ± 18 SE) season, in males (521 m2 ± 23 SE) than in females (450 m2 ± 17 SE) and in adults (576 m2 ± 34 SE) than in juveniles (459 m2 ± 16 SE). However, there were no significant differences between habitats. Sex ratio was not significantly different (p = 0.44) between habitats. Recruitment was significantly higher (p = 0.000) in maize fields (mean = 0.43) than in fallow land (mean = 0.32) and differed significantly over time (p < 0.0001) with the highest recruitment recorded from April to July and the lowest from October to December. Management strategies should focus on managing rodents inhabiting maize fields using methods that affect their recruitment in order to reduce the population increase of M. natalensis.

“…Therefore, it was suspected that many rats breed on the community-owned plantations and migrate to the next block. Many small mammals, expand their home ranges during the reproductive period (Cooney et al 2015). Besides, OHO2 Block haswas a lower place compared to another block, so if it rains, there will be flooding which will cause rats to migrate to higher places.…”

Abstract. Ikhsan M, Priyambodo S, Nurmansyah A, Hendarjanti H, Sahari B. 2020. Species diversity, abundance and damaged caused by rats in oil palm plantation in West and Central Sulawesi, Indonesia. Biodiversitas 21: 5632-5639. Oil palm is one of the plantation commodities which has an important role in Indonesia’s economy. Indonesia is the largest producer and exporter of oil palm in the world with its export value capable of supplying 55.78% of global consumption. Rats are wild animals that are important pests for human life, both in agriculture plantations and urban areas. Rats can damage crops at various stages of plant growth. This study was aimed to determine the species abundance of rats in oil palm plantations, calculate the severity of crop damage due to rats infestation. Three blocks of mature plants were used in OC and OH plantation blocks were used to calculated, crop damage caused by rats, Identify the species of rats, and estimated rats abundance. The results of these studies showed there were four species of rats found in the oil palm plantation, namely Rattus tiomanicus, R. tanezumi, Rattus sp, and Maxomys hellwaldii. However, only R. tiomanicus and R. tanezumi were dominant species. There were significant differences in the number of, sex, and body weight between R. tiomanicus and R. tanezumi. The OC 12 block had the lowest infestation intensity than the other blocks since it was well maintained. The OH 02 block had the highest infestation intensity, infestation area, and abundance due to a lack of maintenance.
