Abstract

Inbreeding, the mating between genetically related individuals, often results in reduced survival and fecundity of offspring, relative to outcrossing. Yet, high inbreeding rates are commonly observed in seaweeds, suggesting compensatory reproductive traits may affect the costs and benefits of the mating system. We experimentally manipulated inbreeding levels in controlled crossing experiments, using gametophytes from 19 populations of Macrocystis pyrifera along its Eastern Pacific coastal distribution (EPC). The objective was to investigate the effects of male-female kinship on female fecundity and fertility, to estimate inbreeding depression in the F1 progeny, and to assess the variability of these effects among different regions and habitats of the EPC. Results revealed that the presence and kinship of males had a significant effect on fecundity and fertility of female gametophytes. Females left alone or in the presence of sibling males express the highest gametophyte size, number, and size of oogonia, suggesting they were able to sense the presence and the identity of their mates before gamete contact. The opposite trend was observed for the production of embryos per female gametes, indicating higher costs of selfing and parthenogenesis than outcrossing on fertility. However, the increased fecundity compensated for the reduced fertility, leading to a stable overall reproductive output. Inbreeding also affected morphological traits of juvenile sporophytes, but not their heatwave tolerance. The male-female kinship effect was stronger in high-latitude populations, suggesting that females from low-latitude marginal populations might have evolved to mate with any male gamete to guarantee reproductive success.

Abstract

International audience; Following several underground mine disasters, the U.S. government changed its safety policies for underground mines. These new regulations state mandatory wireless communications and tracking of personnel. In this context, wireless multimedia sensor networks have been implemented to provide position information and mine surveillance. The recent development of optical camera communications has enable these networks to provide not only multimedia transmission, but also wireless data communications. In this manuscript, we proposed a novel miner video tracking and identification system using wireless multimedia sensor networks and optical camera communication to overcome the problems of video tracking and identifying personnel inside a challenging scenario such as underground mines.

Abstract

International audience; IMU systems can provide positioning without requiring deployed infrastructure. Nonetheless, they suffer from large cumulative errors. On the other hand, visible light communications (VLC) systems can deliver highly accurate positioning as long as communication coverage is assured, which does not always happens in indoor environments. In order to overcome these drawbacks, we propose an opportunistic hybrid VLC-IMU positioning system. The function of VLC system is to refresh the position calculated by IMU system, reducing errors caused by drifting effect and noise, contributing to demonstrate that VLC communication provides the down-link data to IMU refreshing with a correct position. In the other hand, IMU positioning system is used when there does not exist sufficient VLC coverage. Real scenario experiments were carried out to evaluate the performance of our opportunistic method.
