Methods

II. Data set Overview: We conduct annual surveys from 2008. And research time has been set to June from April as a general rule. ? In fiscal 2008 Akkeshi Matsukawaura Banshu tidal flats Tanabe Nanki Nakatsu flats Nagaura flats Ishigaki Kabira Bay Sa In the site trial investigation has been carried out. - Shiokawa is tidal flats began an investigation from the 2009 fiscal year. Site number of flats survey in fiscal 2013 time is 8 sites. - Quantitative research and qualitative research we conduct. Each site is one to three areas (A B C) has two to the three keys in each area ?point (intertidal zone top: U intertidal zone Central: M intertidal zone bottom: L) has been set. ? In each site and quantification study aimed at observing changes in the biomass in the site we conduct qualitative research in order to understand the species diversity.Data associated benthos number of individuals and in it that appeared in the square frame (biological quantitative survey (2mm Sieve)). - At each survey point to place five at random a square frame of 50 cm square was recorded superficial animal. Later collected the subsoil each organism using a core sampler of 15 cm diameter (depth 20 cm) 2 mm the Furutte obtained infauna eyes fit sieve has been recorded. - Superficial animal is the number of individuals who appeared in the 0.25 m2 infauna is the number of individuals that have emerged in the 0.177 m2 de over is data.? LA:cannot translate from the pdf manual to have more detailed methods Unit of abundance = IndCountInt, Unit of biomass = NA
