Lemurs are the most olfactory-oriented of primates, yet there is still only a basic level of understanding of what their scent marks communicate. We analyzed scent secretions from Milne-Edwards' sifakas (Propithecus edwardsi) collected in their natural habitat of Ranomafana National Park, Madagascar. We sought to test whether the scent mark could signal genetic relatedness in addition to species, sex, season, and individuality. We not only found correlations (r 2?=?0.38, P?=?0.017) between the total olfactory fingerprint and genetic relatedness but also between relatedness and specific components of the odor, despite the complex environmental signals from differences in diet and behavior in a natural setting. To the best of our knowledge, this is the first demonstration of an association between genetic relatedness and chemical communication in a wild primate population. Furthermore, we found a variety of compounds that were specific to each sex and each sampling period. This research shows that scent marks could act as a remote signal to avoid inbreeding, optimize mating opportunities, and potentially aid kin selection. 相似文献

The 1992 collapse of the northern cod fishery at Newfoundland, Canada and the subsequent closure of a majority of the inshore
ground fishery has placed a focus on the development of aquaculture within the province. In May 1995 Innovative Fisheries
Inc. of St. John's, Newfoundland, conducted field studies to evaluate the soft-shell clam (edible bivalve molluscs) resources
on three sand flats near Burgeo, Newfoundland. GIS can be used to examine issues regarding the development and management
of the soft-shell clam beds. GIS can also be applied to examine the issue of ‘competing uses’ for the proposed soft-shell
clam aquaculture site. The information presented in this study indicates that GIS is an important tool for the aquaculture
industry. These systems can be used to monitor, quantify and evaluate the soft-shell beds near Burgeo. Management issues such
as water quality, resource sustainability as well as the economic viability of the clam resource can be assessed within a
GIS environment. The results of the analysis in this study suggest potential problems with faecal coliform contamination from
local cottages. Finally, data collection for aquaculture site assessment is required if a resource is to be managed effectively.
GIS applications provide insights into the quality of the physical environment as well as the sustainability of a resource.
However, it is the aquaculture operators who ultimately make the final decisions. 相似文献

With increasing use of fetal ultrasound comes an increase in the detection of clinically silent ‘abnormalities’ which pose diagnostic and management dilemmas for perinatologists and paediatricians. Congenital thoracic malformations (CTMs) (excluding congenital diaphragmatic hernia) are one such example, where a few cases are symptomatic in early life and management options are clear, but the majority are clinically asymptomatic, giving rise to difficulties in defining postnatal management of the well child with a sonographic or radiological lesion. Here, we will outline the prenatal presentation and natural history of CTMs that are not congenital diaphragmatic herniae and briefly discuss the approach to postnatal management, which is covered in more detail in the review by Laje and Liechty in this issue.
