Talvez deva tentar algumas variações de ortografia:
forest reserve » forest research (Expandir a Pesquisa)
reserve system » research system (Expandir a Pesquisa), nerve system (Expandir a Pesquisa), research systems (Expandir a Pesquisa)
crest derived » host derived (Expandir a Pesquisa)
ventral nerve » femoral nerve (Expandir a Pesquisa)
system dan » system data (Expandir a Pesquisa), system dias (Expandir a Pesquisa), system der (Expandir a Pesquisa)
nerve _ase » nerve case (Expandir a Pesquisa), nerve based (Expandir a Pesquisa), nerve cases (Expandir a Pesquisa)
j ventral » _ ventral (Expandir a Pesquisa), a ventral (Expandir a Pesquisa), 2 ventral (Expandir a Pesquisa)
_ase due » case due (Expandir a Pesquisa), base due (Expandir a Pesquisa), phase due (Expandir a Pesquisa)
j crest » _ crest (Expandir a Pesquisa), a crest (Expandir a Pesquisa), 5 crest (Expandir a Pesquisa)

You can also try:

• Europeana
• Digital Public Library of America
• CORE

Pode obter mais resultados ajustando a pesquisa.

• "As palabras AND, OR e NOT podem gerar pesquisas incorrectas; tente utilizar aspas": "(((( j crest derived _ dis ) OR ( a forest reserve system dan ))) OR ( j ventral nerve _ase due ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (((( j crest derived _ dis ) OR ( a forest reserve system dan ))) OR ( j ventral nerve _ase due ))*.
