Knowledge of movement patterns of white-tailed deer ( Odocoileus virginianus (Zimmermann, 1780)) inhabiting landscapes intensively modified by agricultural systems is important to the present and future understanding of deer ecology. Little information exists regarding daily and seasonal movements of white-tailed deer in north-central South Dakota. Therefore, our goal was to determine movement patterns and home-range use of female white-tailed deer in north-central South Dakota. From January 2005 to January 2007, 29 adult (>18 months) and 13 yearling (8–18 months) white-tailed deer were monitored for movement using radiotelemetry. We collected 2822 locations, calculated 76 home ranges, and documented 50 seasonal movements. Mean migration distance between summer and winter home ranges was 19.4 km (SE = 2.0 km). Mean 95% home-range size was 10.2 km2 (SE = 1.2 km2, n = 27) during winter and 9.2 km2 (SE = 1.0 km2, n = 49) during summer. Ambient temperature appeared to be a primary cause of seasonal migration. Additionally, movements exhibited by white-tailed deer in north-central South Dakota were influenced by a highly fragmented landscape dominated by row crops and pasture or grassland.

Specific Variation

Control of introduced predators is critical to both protection and successful reintroduction of threatened prey species. Efficiency of control is improved if it takes into account habitat use, home range and the activity patterns of the predator. These characteristics were studied in feral cats (Felis catus) and red foxes (Vulpes vulpes) in arid South Australia, and results are used to suggest improvements in control methods. In addition, mortality and movement patterns of cats before and after a poison-baiting event were compared. Thirteen cats and four foxes were successfully fitted with GPS data-logger radio-collars and tracked 4-hourly for several months. High intra-specific variation in cat home-range size was recorded, with 95% minimum convex polygon (MCP) home ranges varying from 0.5 km2 to 132 km2. Cat home-range size was not significantly different from that of foxes, nor was there a significant difference related to sex or age. Cats preferred habitat types that support thicker vegetation cover, including creeklines and sand dunes, whereas foxes preferred sand dunes. Cats used temporary focal points (areas used intensively over short time periods and then vacated) for periods of up to 2 weeks and continually moved throughout their home range. Aerial baiting at a density of 10 baits per km2 was ineffective for cats because similar high mortality rates were recorded for cats in both baited and unbaited areas. Mortality was highest in young male cats. Long-range movements of up to 45 km in 2 days were recorded in male feral cats and movement into the baited zone occurred within 2 days of baiting. Movement patterns of radio-collared animals and inferred bait detection distances were used to suggest optimum baiting densities of ~30 baits per km2 for feral cats and 5 per km2 for foxes. Feral cats exhibited much higher intra-specific variation in activity patterns and home-range size than did foxes, rendering them a potentially difficult species to control by a single method. Control of cats and foxes in arid Australia should target habitats with thick vegetation cover and aerial baiting should ideally occur over areas of several thousand square kilometres because of large home ranges and long-range movements increasing the chance of fast reinvasion. The use of temporary focal points suggested that it may take several days or even weeks for a cat to encounter a fixed trap site within their home range, whereas foxes should encounter them more quickly as they move further each day although they have a similar home-range size. Because of high intra-specific variability in activity patterns and home-range size, control of feral cats in inland Australia may be best achieved through a combination of control techniques.

Abstract A commercial sunflower field near Mina, in north-central South Dakota, was selected foi our trial of several insecticide treatments at standard and reduced rates for management of SB larvae. The experiment was arranged in a RCBD with 4 replications, and individual treatment plots were 25 ft long by 10 rows (38 inch spacing) wide. In addition, each plot was bordered by two buffer rows to prevent drift. Pre-application evaluations were carried out using whole-plant visual counts of the number of live SB larvae per plant. Twenty plants were examined from each treatment plot and these counts indicated an average of 11 SB larvae per plant within the test area. Treatments were applied on 11 Ju’ using a CO2-propelled backpack sprayer system with a hand-held 6.7-ft long boom. The boom was equipped with 4 TeeJet 8001 nozzles spaced 20 inches apart, and was calibrated to deliver a spray volume of 15 gpa while traveling at 3 mph. Insecticide efficacy was evaluated at 6 DAT using the same count ing technique and number of samples described for pre-application sampling. Data were analyzed with SAS’ s General Linear Models procedure and means were compared using DMRT.

We monitored the movements of 97 female and 15 male juvenile American black ducks (Anas rubripes) in the vicinity of Moosehom National Wildlife Refuge in eastern Maine and southwestern New Brunswick from September through mid-December, 1985–1987. Movements were described by estimating home ranges and radial movements from the primary roost marsh. Overall home range sizes averaged 4987 ha (range 54 – 28 070 ha), and maximum distances moved from the roost averaged 9.9 km (range 0.9–42.8 km). Home ranges were linear (linearity index 2.8), and home range area and distance of movements from the roost both increased monthly. Ducks that used >15% riverine habitat had larger home ranges and moved greater distances from the roost than ducks using <15% riverine wetlands. Movements did not differ between ducks usually alone and those usually in flocks. Juvenile black ducks moved in small flocks and were often alone (34% of 355 observations). Most ducks showed fidelity to one roost-marsh complex from September until migration in late November. Daily and seasonal movement patterns were similar to those predicted for refuging systems.

Wood Turtle

We studied the home ranges and seasonal movements of 20 wood turtles (Clemmys insculpta) living near the northern limit of their distribution in the Mauricie region, Quebec, Canada. We found average home-range areas of 28.3 ha. Wood turtles showed site fidelity; there was an average overlap of 60.7% in their home ranges, and 88.8% of the home-range centroids were not significantly different for the 2 years of the study. The home ranges were larger than those reported from studies in more southerly locations, leading us to hypothesize larger home-range territories with increasing latitude. Our analyses indicate that turtle movements could be grouped into four distinct activity periods during the active season: the prenesting, nesting, postnesting, and prehibernation periods. We found that wood turtles were closely associated with streams. Based on the importance of this habitat for the species, we suggest the establishment of protected buffer strips along streams used by wood turtles.

Abstract A grower-established sunflower field (planted on 25 May with a seeding rate of 23,300 per acre) was found to have sufficient SB larvae (5 per plant) to conduct our insecticide evaluations. This site in north-central South Dakota (Ipswich) was used to evaluate 3 pyrethroid insecticides at standard and reduced rates for management of SB larvae. Plots were 25 ft long by 8 rows (36 inch spacing) wide and the study was arranged in a RCBD with 4 replications. Treatment plots were buffered by 2 untreated rows to prevent cross-contamination between plots due to insecticide drift. Pre-application evaluations used whole-plant counts which were carried out on 20 plants per plot. Treatments were applied to plots on 2 Jul at V-8 stage of sunflower physiological development. Applications were made using a CO2-propelled backpack sprayer system equipped with a 6.7 ft long, 4-nozzle (TeeJet 8001 flat fan; spaced 20 inches apart) boom. The system was calibrated to deliver a spray volume of 15 gpa while traveling at 3 mph. Efficacy was evaluated at 7 and 24 DAT using the same counting technique and number of plants sampled as pre-application sampling. Data were analyzed with SAS’s General Linear Models procedure and means were compared using DMRT.

The study of movement patterns and home range is fundamental in understanding the spatial requirements of animals and is important in generating information for the conservation and management of threatened species. Ndumo Game Reserve, in north-eastern KwaZulu-Natal, bordering Mozambique, has the third largest Nile crocodile (Crocodylus niloticus) population in South Africa. Movement patterns of 50 Nile crocodiles with a total length of between 202 cm and 472 cm were followed over a period of 18 months, using mark-resight, radio and satellite telemetry. The duration of radio transmitter attachment (131 ± 11.4 days) was significantly and negatively related to total length and reproductive status. Satellite transmitters failed after an average of 15 ± 12.5 days. Home range was calculated for individuals with 10 or more radio locations, spanning a period of at least 6 months. There was a significant relationship between home range size and total length, with sub-adults (1.5 m – 2.5 m) occupying smaller, more localised home ranges than adults (> 2.5 m). The largest home ranges were for adults (> 2.5 m). Home ranges overlapped extensively, suggesting that territoriality, if present, does not result in spatially discrete home ranges of Nile crocodiles in Ndumo Game Reserve during the dry season. Larger crocodiles moved farther and more frequently than smaller crocodiles. The reserve acts as a winter refuge and spring breeding site for an estimated 846 crocodiles, which also inhabit the Rio Maputo during the summer months. Nile crocodile movement out of the reserve and into the Rio Maputo starts in November and crocodiles return to the reserve as water levels in the floodplain recede in May.Conservation implications: Movement patterns of Nile crocodiles show the important role the reserve plays in the conservation of Nile crocodile populations within the greater Ndumo Game Reserve–Rio Maputo area.

The sika deer (Cervus nippon yesoensis) population in the Ramsar-listed Kushiro Wetland has increased in recent years, and the Ministry of the Environment of Japan has decided to take measures to reduce the impact these sika deer are having on the ecosystem. However, their seasonal movement patterns, i.e., when and how the deer inhabit the wetland, remain unclear. Thus, we examined seasonal movement patterns and the population structure of sika deer in the Kushiro Wetland from 2013 to 2015 by analyzing GPS location data for 28 hinds captured at three sites in the wetland. Seasonal movement patterns were quantitatively classified as seasonal migration, dispersal, nomadic, resident, or atypical, and the degree of wetland utilization for each individual was estimated. The overlap areas of population-level home ranges among capture sites were calculated for both the entire year and for individual seasons. Our results showed that approximately one-third of the individuals moved into and out of the wetland during the year as either seasonal migrants or individuals with atypical movement. Some of the individuals migrated to farmland areas outside the wetland (the farthest being 64 km away). Half of the individuals inhabited the wetland all or most of the year, i.e., 81–100% of their annual home range was within the wetland area. The movement patterns of these deer were classified not only as resident but also as seasonal migration, dispersal, nomadic, and atypical. Even among individuals captured at the same site, various seasonal movement patterns were identified. Annual population-level home ranges showed little to no overlap, and seasonal population-level home ranges were completely segregated among capture sites. Individual deer used the wetland either seasonally or year-round, and some populations inhabiting the wetland had sub-populations with different seasonal movement patterns, which need to be considered to achieve more effective ecosystem management including deer management in the wetland.

Rhizobacteria have been shown to be phytotoxic to leafy spurge in laboratory assays. This field study investigated the influence of two strains ofPseudomonas fluorescens[Trevisan, (Migula)], deleterious rhizobacteria (DRB), on root weight, root bud number, and root carbohydrate content of leafy spurge at three sites located in northeast and north-central South Dakota. Soils were inoculated with 2 g of starch-based granules containing no bacteria or starch granules containing 108colony-forming units (cfu)/g of either bacterial strain LS102 (Montana origin) or LS174 (South Dakota origin). Bacterial strains were detected on root samples from treated areas. Root weight and root carbohydrate content were reduced about 20% compared to roots from control plots.
