Marking as a decision factor in the choice of a new resting site in Lasius niger
In ants, aggregation is mainly based on the attraction between individuals. We confirmed the existence of ground marking in Lasius niger and demonstrated its influence on the aggregative behaviour of ants: the place of the gathering is leading by the existence of a ground marking which favours clustering by increasing the rate of the process but does not change the aggregation level. This factor could play a role in the choice of a new nest site and in the spatial distribution of ants inside the nest. This marking, presuming to have a long duration, could represent an external memory which could play an important role in various situations such as the choice of new nest or the reorganisation of ants after a disturbance.
Abstract This paper aims to investigate factors affecting the hotel occupancy rate of the sole official gaming destination in China – Macao. Data from 39 hotels (3–5 stars) during the period of 2008–2011 have been applied. Three categories of determinants forming nine hypotheses were tested and all are supported except seasonality. Eight factors were identified exercising significant influences on the hotel occupancy rate in the destination. A regression model of 51.5% predictability is generated to predict the hotel occupancy rate in the destination. The study is concluded with insights to hoteliers who are interested to invest or operate in a gaming destination.
