Diet

Diet contains a series of eight fields for specifying the use of different dietary elements. The fields are as they appear on the page are labelled ‘Vertebrates’, ‘Invertebrates’, ‘Fruit’, ‘Flowers' , ‘Seeds’, ‘Grass’, ‘Leaves' and ‘Roots’. However, please note that 'Flowers' should also contain Pollen/Nectar/Gum, 'Leaves' should also contain Branches/Bark and 'Roots' should also contain Tubers. The information entered in these fields must be qualified using three drop-down lists:

Diet Measure
Brief definitions of these measures are displayed in the Measure Description box when a selection is made from the list. The measures are given in order of preference. In all cases, ‘0’ should only be used to indicate the definite absence of an element from that species diet.

• % unspecified — Values must not exceed 100, but can be less than 100.
• % volume — enter the percentages of each dietary element. Values must not exceed 100, but can be less than 100.
• % mass — Values must not exceed 100, but can be less than 100.
• % time spent — Values must not exceed 100, but can be less than 100.
• % energy — Values must not exceed 100, but can be less than 100.
• Ranked — number all dietary elements reflecting the ranked importance of each category, 1 (most) to 8 (least). Several categories can have the same number if they contribute equally to the diet. Where ranks are used and two or more categories are given equal rank, number the ranks (including the tied ranks) sequentially - ie, (1,1,2,2) rather than (1,1,4,4).
• Qualitative — enter a ‘1’ to indicate presence in the diet for each category listed in the source.


Measurement Duration

• ‘Unspecified’
• ‘Year round’
• ‘Part of year’


Diet Assessment Method
Indicate how diet was assessed from the following list:
• Unspecified — the source does not report how diet was assessed.
• Feeding Observation — observation of feeding in live animals.
• Stomach Contents — analysis of stomach contents.
• Scat Contents — analysis of scats, droppings etc.

Generic value types: Sample Size, Captivity Status, Sex and Source Type.
