Brown tides of Aureococcus anophagefferens occur in shallow mid-Atlantic bays in the USA and attain peak summer densities of ~1000 to 2800 cells μl–1. Blooms coincide with the period of spawning and planktotrophic larval development of the hard clam Mercenaria mercenaria, a commercially important bivalve in the region. This laboratory study investigates the effects of A. anophagefferens (toxic ...

A fundamental study by Ens et al. (1992, Journal of Animal Ecology, 61, 703) developed the concept of two different nest-territory qualities in Eurasian oystercatchers (Haematopus ostralegus, L.), resulting in different reproductive successes. "Resident" oystercatchers use breeding territories close to the high-tide line and occupy adjacent foraging territories on mudflats. "Leapfrog" oystercat...

Water level reduction with GNSS [FIG Commission 4 Working Group 4.2 2006, Dodd and Mills 2011] requires the availability of the ellipsoidal heights of CD, i.e. the Lowest Astronomical Tide (LAT) as adopted by the International Hydrographic Organization [International Hydrographic Organization, 2011, Technical Resolution 3/1919]. LAT is defined as the lowest tide level to occur under average met...

When China turned its back on the Cultural Revolution, it aimed to build a thriving capitalist sector. It got one. Now, it wants a world-class research enterprise. How far has it progressed in the biosciences, how did it get there, and how far does it have to go?

The shoreline is one of the most important features on earth’s surface. It is valuable to a diverse user community. But the dynamic nature of the shorelinemakes it difŽ cult to be represented in a naturally dynamic style and to be utilized in applications.The ofŽ cially usedshoreline,for examplein nauticalcharts,is the so-calledtide-coordinatedshoreline. It is also the shoreline that makes the ...

in this study, surface water samples were collected monthly from five stations inclduing nayband bay, assaloye, dayer, kabgan and bushehr from december 2012 to june 2013. sampling stations were chosen according to data being collected during algal bloom caused by cochlodinium polykrikoides in 2008. a total of 45 genera of phytoplankton belongs to four classes were totally identified accounting ...
