Talvez deva tentar algumas variações de ortografia:
variation patterns » radiation patterns (Expandir a busca), venation patterns (Expandir a busca), activation patterns (Expandir a busca)
decrease variation » disease variation (Expandir a busca), decrease migration (Expandir a busca), decrease predation (Expandir a busca)
cross decreased » causes decreased (Expandir a busca), corn decreased (Expandir a busca), loss decrease (Expandir a busca)
decrease cross » decrease costs (Expandir a busca), increase cross (Expandir a busca), decrease sucrose (Expandir a busca)
decrease to » decreased to (Expandir a busca), decrease toc (Expandir a busca), decrease the (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease AND decrease cross decreased ) OR ( decrease to decrease variation patterns ))~.
