This is the first study using geolocators (global location sensing, GLS) to track the movements of a pelagic tropical seabird. We used GLS to describe at-sea distribution and activity patterns of wedge-tailed shearwaters Puffinus pacificus breeding on Aride Island, Seychelles, in the late chick-rearing, non-breeding and pre-breeding periods. During late chick-rearing and pre-breeding periods, shearwaters foraged relatively close to the colony. In the non-breeding period, shearwaters; were found on a west-east gradient along the equator, between 5 degrees N and 10 degrees S. Some of the tracked individuals showed little dispersion, staying as close as 1000 km to Aride Island, while others travelled 3500 km to the Central Indian Ocean Basin. Individual core areas of activity showed little overlap. Overall, wedge-tailed shearwaters showed short-distance movements and exploited relatively unproductive oceanic waters. At-sea distribution largely matched that of yellowfin and skipjack tunas, emphasising the importance of the association with subsurface predators rather than associations with physical oceanographic features that enhance primary productivity. During the non-breeding period, the feeding activity of, shearwaters was mainly concentrated in the daylight period, when tunas also forage. A different behaviour, characterised by a much lower proportion of the night sitting on the sea surface, was recorded in the pre-laying exodus of 1 female to more productive waters, suggesting a different feeding strategy and/or targeting of different prey. Knowledge of the at-sea distribution of wedge-tailed shearwaters allows quantification of the overlap with industrial fisheries, which will be crucial to devise fisheries policies for the Indian Ocean with important implications for the conservation of this species.
recently, according to the relevant survey shows that 66.3% of the visited sites in 2009 annual revenue of 10 thousand yuan, 17.8% of the site’s annual revenue of 10 thousand -5 million, annual revenue of more than 100 thousand of the site is only 7.3%. Most of the profitable sites mainly advertising revenue, the proportion of up to 50.1%, followed by accounting for 12.7% of the game charging profit model, only 11.6% of the site in e-commerce form profitable.
: small in size and as everyone knows the website information on the web site, and there is no certain technical strength, the popular model has been difficult to win in competition, therefore, can only find personalized, more popular, there is a certain market share and become the developing trend of the mode of.
according to iResearch data published in 2009 projections, this year’s first quarter online shopping transactions amounted to 53 billion 400 million yuan. IResearch also expects that with the arrival of the peak season, China’s online shopping market in the two quarter will usher in substantial growth.
from the earnings data in 2009 and the scale of online shopping site, we can see that in the form of electronic commerce as profit is the most promising, the small and medium-sized enterprise website and some small website profit odds in e-commerce will be great.
however, the electronic commerce website currently has a certain scale, the lack of some of the more outstanding website, how to create a cohesive website? To solve this problem, the author interviewed the global e-commerce experts linkage of the world (www.72e.net/? Cid=luoluo), the responsible person said: sticky website from the following aspects: to create
first, sticky site full of bait. Sticky site is like a fish pond, in addition to the home page, but also in the site is full of bait, in order to attract customers’ eyes, to plan the site, product layout and sales planning combination.
second, website products to focus, must have a unique selling point. Find your product features, choose the sale point, focus on the site, coupled with a number of other service delivery, even more ordinary products can also highlight their own personality, will naturally attract customers.
third, select a unique virtual host. In the case of everything that only owes the east wind, the choice of a virtual host is a guarantee for the efficient operation of individual websites.
any website without stickiness will lose the meaning of existence, the so-called "sticky" refers to the website to the customer site without any adhesive viscosity will lose the meaning of existence, the so-called "sticky" refers to the website to the customer adhesion.
is worth mentioning is to create a sticky website is one of several aspects are complementary to each other, must be several aspects to play together or so to achieve little effect, in addition, choose a good space for priority among priorities priority, imagine a well-designed web site, because the virtual host can not choose well, "
