Monitoring lidia cattle with GPS-GPRS technology; a study on grazing behaviour and spatial distribution. Veterinaria México OA. 2017;4(4). doi:10.21753/vmoa.4.4.405.The behavior of grazing cattle has not been studied as much as farmed animals. In certain breeds, reared in extensive systems, human presence can cause an interruption or modification in their ethological patterns moving away from the person watching them. The use of technologies like a Global Position System and a General Packet Radio Service (GPS-GPRS) allows monitoring bovine animals exploited in extensive systems, providing information in real time about distances traveled, home range grazing areas, frequented territories, behavior patterns, etc. In the present work, GPS-GPRS collars were used to monitor 21 cows of to the lidia cattle breed, with different ages, and from three different herds in the Salamanca province (Spain). The study lasted 8 months, the animals being distributed in enclosures of different dimensions and orographic characteristics, geographic position data being collected every 15 minutes. The proper functioning of the GPS-GPRS devices was proven and home range grazing area for each animal has been calculated, with an average of 56 hectares. A graph of animals’ circadian rhythm with the distances traveled for hours has been developed. A trend was observed to start daily activity hours before dawn, diminishing its activity with the evening and overnight, with a night’s rest phase of about 7 hours. We also report daily distance traveled (3.15 km on average), finding differences depending on age, available space allowance/animal, daylight and theseason. Our results could be of relevance for a better pasture management using enclosures of size that increase the use of all the surface available.Figure 3.

Territorial Boundaries

Long-term stability of territorial boundaries has not been well documented in canids. To evaluate the prevalence of long-term spatial stability of coyote (Canis latrans) home ranges, we compared the overlap of territorial boundaries and the spatial distribution of telemetry locations of packs in southeastern Colorado. From August 1983 to July 1988 (period 1), 16 coyotes from six packs were radio-tracked. From April 1996 to August 1997 (period 2), 12 coyotes from six packs were captured and tracked in the same area. Mean percentage of overlap of pack ranges was 89.8 ± 8.3% (±SD) for period 1 ranges over period 2 ranges and 55.8 ± 14.4% for period 2 ranges over period 1 ranges. Mean percentage of overlap of the 30% core area of the home ranges was 65.2 ± 13.9% for those of period 1 over those of period 2 and 66.3 ± 28.7% for those of period 2 over those of period 1. Despite substantial overlap of home-range and core-use areas, there were significant differences in the distribution of locations between periods in five of six home ranges. This suggests that, although packs are faithful to one site (i.e., boundaries remain similar over a period of years), their use of the site (i.e., distribution of locations within the range) may change temporally.

Distribution Of Resources

This paper investigates the spatial distribution of resources, production activities and poverty in Ghana. The study found that the presence of natural resources in an area over a period of time greatly influences industrial activities in that locality. Moreover, given that firms or manufacturing industries will usually site their business ventures close to the sources of resource attraction, the processes of production including value addition, packaging, and refinery largely becomes vibrant in resource rich areas than less-resource zones. In Ghana, there seems to be an uneven distribution of natural resources across the administrative regions and ecological zones. This kind of distribution has resulted in the creation of additional jobs in areas endowed with natural resources. Data for the studies was obtain from Ghana statistical service Spatial distribution of natural resources positively influences most important production activities in the discovered areas. A boom in production activities within an areas certainly reflect on the poverty incidence of the people since it creates both direct and indirect employment opportunities in that area. The paper suggests diversification of the economy, equitable allocation of resources to deprived areas to ensures comprehensive development and poverty alleviation in all aspects of life of the ordinary Ghanaian .Government needs to as well put in the needed measures to ensure people gets direct benefits from resources exploited in their communities as most of these exploitive activities pose negative externalities to the people.

Main Food Item

AbstractA Speleomantes ambrosii population living in an artificial tunnel in NW Italy was studied for two consecutive years. Activity on the walls varied cyclically in relation to seasonal temperatures and food abundance. The main food item was the trogloxenic dipteran Limonia nubeculosa, which accounted for more than 80% of the total ingested prey by volume. Juvenile cave salamanders had a broader trophic nich than adults. Oviposition and juvenile recruitment appeared to be seasonal. The spatial distribution inside the tunnel was related to microhabitat heterogeneity and particularly to the distance from the entrance. Juveniles were observed outside or close to the entrance more often than adults. Movement of adult salamanders were generally low and averaged 7 cm/day; some repeatedly recaptured individuals had a mean home range of 6 m2.

AbstractThe spatial distribution of Sceloporus virgatus in the Chiricahua Mountains of Arizona was studied during the breeding season. Male home ranges were, on average, more than four times larger than those of females. Home range overlap of both sexes was extensive, with most individuals overlapping multiple males and multiple females. Home range overlap of males with females was significantly correlated with an independently calculated estimate of male mating success. For most females (71%), one of the males overlapped a substantially larger portion of her home range than any other male. Similarly, for most females (76%) a single one of the overlapping males courted the female more often or was sighted at closer distances to the female. The remaining females did not associate primarily with a single male.

Individuals that occupy restricted home ranges for long periods have little chance to sample surrounding habitats and may only be able to respond to changes in the distribution of resources at very local scales. Processes leading to the selection of a home range, therefore, potentially have an important bearing on individual fitness and, ultimately, on population structure. In this study, movements associated with the establishment of home ranges by golden perch (Macquaria ambigua) and common carp (Cyprinus carpio) in an Australian lowland river were examined using radiotelemetry. To examine behaviour associated with exploration and settlement into new home ranges, fish were artificially translocated into an unfamiliar river section. Although there was substantial intraspecific variation in patterns of movement, all fish tracked over the entire study period eventually settled into restricted home ranges. Several fish of both species either moved away from established home ranges and settled in new areas, or undertook large-scale movements and subsequently returned to the original home range. It is suggested that such movements may provide a mechanism by which fish can reap the benefits of home-range occupation whilst still being able to respond to changes in the distributions of spatially and temporally dynamic resources.
