MASTIF home

As of Dec 19 2021 there are Inf seeds recovered from seed traps and 26,520,521 crop counts of cones, fruits, pods, and seeds. There are 900,549 observed trees, 21,335,969 tree-years, and 2251 species from 145 families. The network includes 5522 plots and iNat hectares.

Trees are observed outside their native ranges to increase the climate/habitat space for fecundity responses. Species in this table show the region where they are native or naturalized followed by columns for tree-years where they were observed. We are continually adding observations though monitoring of inventory plots and opportunistic sampling using iNaturalist. For model fitting we include species observed in multiple years with a minimum number of trees depending on the analysis. The native/naturalized column and column names include AFR (Africa), ASIA (Asia), EUR (Europe), NAE (eastern North America), NAW (western North America), PAC (Pacific islands), and SCA (South and Central America, including Caribbean Islands).

Wild/commercial relatives

Species in the MASTIF study with close commercial relatives include the following:

Olea europeae sylvestris differs from commercial olive Olea europeae europeae in fruit size and stress response genes. Distributions overlap in southern WEA.

Persimmons (Diospyros) in NA (D. virginiana), WEA (D. lotus), and SA (D. mespiliformis) are not direct ancestors of the commercially grown D. kaki that is native to EEA.

Prunus avium is wild and grown commercially in WEA. It is naturalized in NA.

The almond Prunus amygdalus differs from its domestic relative by a single gene that blocks amygalin (cyanide) production.

Apple species Malus orientalis/baccata/sylvestris were not the direct ancestor of M. domestica, although M. sylvestris (European wild apple) readily hybridizes. All three occur in WEA.

Juglans regia, wild in WEA, is commercially grown in WEA and NA. [J. nigra of NA is naturalized in WEA].

Pistacia lenticus and P. terebinthus, abundant in southern WEA, are not direct ancestors of commercial pistachio P. vera, which is grown in the same regions.
