Create statistics by features in QGIS

[المشرف العام]

I've a polygon layer for parcels in a landscape protection area and a point layer, contains zoological data (e.g species, entities, etc.). How can I make a statics for each polygon, contains the list of observed species, the count of observations by species and the sum of entities by species? I would like to make it in QGIS with shapefiles or spatialite database.

Thanks for your help!
