Concatenate row data in columns B-F based on duplicate value in column A

Hi,

I realise that this is probably a very simple problem but I can't find a solution so am posting it here.

I have a Excel 2007 spreadsheet with species names in the first column (A) and occurrence codes in the following five columns (B-F).

Where there are duplicate species names in column A I would like concatenate the occurrence codes into one row and delete the empty rows.

Attached is a example of the my current data and desired output.

Thanks in advance for any help
