Talvez deva tentar algumas variações de ortografia:
vegetation pattern » vegetation patterns (Expandir a busca), visitation pattern (Expandir a busca), vegetation alters (Expandir a busca)
pattern decrease » faster decrease (Expandir a busca), litter decrease (Expandir a busca), protein decrease (Expandir a busca)
code vegetation » some vegetation (Expandir a busca), zone vegetation (Expandir a busca), border vegetation (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
code code » code cdc (Expandir a busca)
of python » _ python (Expandir a busca), in python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code vegetation pattern decrease ) OR ( of python python python programming ))~.
