Spider monkeys eating wood in Lacandona rainforest, Mexico.

<p>Panels show consumption of decayed wood from <i>Licania platypus</i> (A) and <i>Ficus</i> sp. (B), and live wood from young branches of <i>L. platypus</i> (C).</p

Plant species exploited for live and decayed wood by spider monkeys (<i>Ateles geoffroyi</i>) in continuous forest and forest fragments in the Lacandona rainforest, Mexico.

<p>Species are listed by order of importance in the diet.</p>a<p>Only trees with ≥10 cm in diameter at breast height were considered (see further details in Chaves et al <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0025070#pone.0025070-Chaves1" target="_blank">[24]</a>). Although dead standing trees were not observed during the vegetation samplings, our observations through the home ranges of each monkey group indicated that their density was <i>ca.</i> 0.03 trunks/10,000 m² in both habitat types.</p>b<p>Index of preference.

Average (± SD) content of minerals of different plant items in seven food species for spider monkeys (<i>Ateles geoffroyi</i>) in the Lacandona rainforest, Mexico.

Nutritional composition of plant food species.

<p>Average (±SD) content of macronutrients (A,B) and minerals (C,D) of different plant items exploited by spider monkeys in Lacandona rainforest, Mexico. In each figure, nutrients are listed in decreasing order (from left to right). DW1 =  decayed wood of <i>L. platypus</i>; DW2 =  decayed wood of <i>Ficus</i> spp.; LW =  live wood; MF =  mature fruits; IF =  immature fruits. Bars sharing a letter are not significantly different (contrast tests, <i>P</i>>0.05).</p
