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.
November 6, 2009, Beijing has become very cold, and the sky is still fluttering with snow. Although I know that tears can not change the result, but still can not help living in the eyes of rotation. For various reasons, my server hard disk is broken and all data is gone. This day, I recovered from the company is located in China Electronics Building off Booz data, go to the digital building data recovery center, then to the national Internet Information Center zizhuqiao. The answer is only the same: the data cannot be recovered.
but no way, with deep hatred and resentment, the most recent backup can be found is September 16, 2009. This means that more than 20 thousand reviews, more than 10 thousand diaries, and more than 6000 new user data are completely lost, which is almost fatal to a web site. What has happened has been lost, and the data has been irretrievable, but it’s still up to you to deal with it. Finally, in November 13th, the new hard disk was replaced and the website reopened.
expected, I received numerous users reviled, because this is all my own mistakes. Many, many of the older users are giving similar testimonials, "never coming again."". I tried my best to stay, but after all, many familiar ID, I never saw again. I do not know such a loss, I would like to still be able to bear the diary network?.
for the next few days, I want to keep a diary. Black and white Bannner below the big announcement, clear to the user, and the user through frank communication, is a part of the user to restore the shilly-shally. People often say, Felicity never turns out in pairs. after November 20th, when the Disasters pile up on one another., popularity gradually restored, but the site was sustained DDoS attacks. Site access is extremely slow, and even my administrator does not want to go to the diary, not to mention users,
November 21st morning, room data show that the site continued to be large-scale DDOS attacks, the peak value of 300M per second. The computer room calls me, saying that it is to break the net, otherwise, the other server of the whole cabinet will be implicated too. In this way, the site is paralyzed again. This time I move very quickly, can not let the user disappointed again, that night, I contacted my IDC, increased the bandwidth, changed to the new computer room, and added the hardware firewall. The speed of website access has finally been improved qualitatively. DDOS attacks can’t affect my site for the time being.
Maybe God is using this attack
to test me, after this period of time to remedy, the vast network diary to like his name, not only the flow restoration, snatched from the jaws of death, but also reached a historical high, I also gain a lot of lessons.
1, the data should be backed up in time. Now my data can not do real-time backup, but at least once a day backup database, so even if there is a similar accident, you can also reduce the loss to its lowest point.
2, increase website speed. After changing the engine room, >
