Ranging behaviour and sleeping site selection are important aspects of primate ecology in their adaptation to the environment. Several non-exclusive factors have been suggested to explain sleeping site selection in primates: predation avoidance, food resources proximity, interactions with conspecifics, physical comfort, and parasite avoidance. We tested the role of some factors in a group of Macaca fascicularis living in a human-modified landscape in Bali Barat National Park, during 3 months from April-June 2011. Despite the large area of available forest, the group’s home range was centred around human-settlements (park headquarters). The home range size, as well as the average daily range and daily travel, decreased over the study months. These results correlated with the increase of human presence inside the park over the corresponding months. Regarding sleeping sites, the use pattern also seemed to be influenced by the attraction to human settlements. Indeed, macaques slept more than expected close to human-settlements and this tendency increased over the months. 75% of the 56 observed nights were spent inside the core area, an argument for the role of intergroup competition avoidance. In contradiction with the predation avoidance assumption, the DBH and the height of sleeping trees were not significantly greater than those of control trees. On the other hand, most of sleeping trees had no liana on the trunk and a high arboreal connectivity with surrounding trees. Also, the rate of consecutive sleeping site reuse was very low (12%), minimizing the detection by predators. We conclude that the main strategy of this M. fascicularis group could be sleeping not too far from humans because it is advantageous for predator avoidance and proximity to human food, but that additional influences should not be neglected.

Ranging behaviour and sleeping site selection are important primate behavioural traits likely to vary under environmental changes. We tested the role of ecological (predation avoidance) and anthropic (human proximity) factors in Macaca fascicularis range use, an edge species known to prefer living along forests borders and in the vicinity of human settlements. Data result from 56 day follows of one group of Macaca fascicularis exploiting a human-modified landscape within Bali Barat National Park (Indonesia). Observations allowed identifying and describing 17 sleeping sites and the characteristics of 37 sleeping trees. Despite a large forest area available, the group’s home range centred around human settlements. The home range size, average daily range and daily travel decreased over the study period, while the human presence inside the park increased over the corresponding months. The proximity with humans also influenced the pattern of sleeping sites use; macaques slept more than expected close to human settlements and this tendency increased over the study period. In contradiction with the predation avoidance assumption, macaques did not choose sleeping trees significantly taller and larger than other trees available. We conclude that the observed sleeping site strategy (sleeping near humans) could be advantageous in terms of predator avoidance and proximity with human food, but additional influences should not be neglected.

We describe the development of a multipoint nonparametric quantitative trait loci mapping method based on the Wilcoxon rank-sum test applicable to outbred half-sib pedigrees. The method has been evaluated on a simulated dataset and its efficiency compared with interval mapping by using regression. It was shown that the rank-based approach is slightly inferior to regression when the residual variance is homoscedastic normal; however, in three out of four other scenarios envisaged, i.e., residual variance heteroscedastic normal, homoscedastic skewed, and homoscedastic positively kurtosed, the latter outperforms the former one. Both methods were applied to a real data set analyzing the effect of bovine chromosome 6 on milk yield and composition by using a 125-cM map comprising 15 microsatellites and a granddaughter design counting 1158 Holstein-Friesian sires.

The generalization of the geometric mean of positive scalars to positive definite matrices has attracted considerable attention since the seminal work of Ando. The paper generalizes this framework of matrix means by proposing the definition of a rank-preserving mean for two or an arbitrary number of positive semi-definite matrices of fixed rank. The proposed mean is shown to be geometric in that it satisfies all the expected properties of a rank-preserving geometric mean. The work is motivated by operations on low-rank approximations of positive definite matrices in high-dimensional spaces. [less ▲]

With increasing oil price and growing interest in cutting green house gases emissions, waste heat recovery techniques appear as a very promising path to enhance engine thermal efficiency. Thermoelectricity and Rankine cycles are two possible ways to recover thermal energy. The Rankine cycle shows the highest potential due to its higher cycle efficiency in comparison with the current state-of-the-art thermoelectric materials intrinsic conversion ratio. This paper will focus on the Rankine cycle system. The first part of the paper lists and describes the constraints of a heat recovery Rankine cycle system associated to a long haulage truck: limitation of heat available in the heat source, vehicle heat rejection constraints, safety and environmental issues for the working fluid, and backpressures occurring during the heat recovery process. The second part of the paper presents a 0-D simulation model of a Rankine cycle system. It is shown how the model can be used to compare the performance achieved with several working fluids. Moreover, basic thermodynamic limitations of the system are underlined. Conclusions are drawn concerning the limitation of using only thermodynamic simulations. The performance of the condenser (and its influence on the overall performance) has been investigated more in details, which is shown in the third part of the paper. This was carried out based on a 1-D simulation model of the condenser. Influence of the condenser size and ram air effect are discussed, and the impact on the Rankine cycle is assessed. [less ▲]
