Was calculated from the availability in months of each of the species in the market. We considered twelve months, so that the value of each species was divided by 12 and then was calculated their percentage.
Was based on Pieroni (2001) whom has a numerical scale.
2
Life cycle
We aggregated a number when a species plant was 1=annual, and a 2= perennial.
3
Percentage Markets
Number of markets where a species plant was found, maximum 6 markets, minimum 1 market. Each specie value was divided between maximum (6) and its percentage was calculated.
Number of stalls where a species was found in each market was summed. Total number of stall was divided between numbers of total stalls to obtain the average by market. Total markets stall were summed and its average was obtained.
3
Average price
Number of stalls where a species was found in each market were summed. Total numbers of stalls were divided between numbers of total stalls to obtain the average of stalls from a market. Total markets stalls were summed and its average was obtained.
3
Sales volume
We summed total sales for all the markets in the same week or month. Average was conducted when we had information of two or more weeks or months.
3
Interchanged ways
We considered three types of interchanged of products, 1=interchanged just by money, 2= interchanged by corn and or by money, 3=interchanged just by corn.
Appendix 5. Description of partial canonical analysis variables used in the database of 59 edible plant species. F factor 1: 1 = Management, 2=Ecological, 3=Socioeconomic. Risk index were applied to this data. Data were considered found a gradient from low to high risk, by that we changed the scale of some factors such as these with an asterisk. We expected to construct a risk index which higher values would indicate higher risk. In those cases where values of variables that go in opposite direction, such as management factors, the values were substracted to 1, in order to change the range.

Description
1
Ecological Status*
Conditions of habitat of a plant species, wild=1, weed or ruderal =2, domesticated=3. To obtained a number each category was considered, e.i. a species plant weed (2) and wild(1), its value was: 2+1=3
Characteristics of the management, is a gradient of complexity, if it´s recollected (1), tolerated (2), promoted (3), protected (4) or cultivated (5). Each species plant was considered as a number. When a species plant had 2 o more categories those were summed, such as, tolerated (2) and promoted (3), the result was 2+3=5.
1
Categories of management types
Numbers of categories were summed, by example when a plant had two categories those were summed, such as recollected plus protected, two categories, were 2.
1
Management systems*
Spatial system where a plant is present, since natural vegetation (1), secondary vegetation (2), agroforestal system (3), homegardens (4), intensive system (5). When a species plant had more than one categories those were summed, i.e. : natural vegetation (1), homegardens (4)= 1+4 =5.
Number of categories were summed, by example when a plant had two categories, those were summed, such as present in homegarden plus agroforestal system, in total we have 2 categories
1
Uses*
Number of uses considered on database of Blancas et al 2010 and bibliographic information.When we obtained more than one value those were summed.
2
Percentage presence in plots*
Number of plots where a species was present obtained through revision of its presence in 98 samples. Each cell value was divided between 98 and after we calculated its percentage.
