Ant-plant interaction networks empirically sampled by us throughout the Neotropical Cerrado savanna <br

Ant–diaspore specialization.

<p>Comparison between the observed (vertical line) differences of <i>H</i>_<i>2</i><i>’</i> (specialization) values and the randomized differences of <i>H</i>_<i>2</i><i>’</i> values (<i>Z</i> test, all <i>p</i>-values > 0.05), between A) fruit consumption and diaspore removal networks; B) fruit consumption and total networks; C) diaspore removal and total networks.</p

Completeness of the sampling of ant–diaspore interactions.

<p>Accumulation curves for distinct pairwise ant–diaspore interactions, recorded over 12 months in the Brazilian Savanna. The error bars represent the 95% confidence intervals.</p

Ant–diaspore networks and the relation between the morphological traits.

<p>Ant–diaspore networks and relationship between the mandible size and diaspore size in the Brazilian Savanna involving three types of interactions: A) the total network; B) diaspore removal network; C) fruit consumption network. Within each network, nodes represent one plant species (yellow square) or ant species (red circle) and lines represent ant–diaspore interactions. Relationship between the mandible size of ants and the size of the diaspores on which they D) remove (F_1,43 = 12.173, p < 0.01) and E) feed (F_1,15 = 0.210, p = 0.886). The area between dashed lines represents the linear best-fit model (95% confidence intervals). Species name code are in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0201117#pone.0201117.s001" target="_blank">S1 Table</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0201117#pone.0201117.s002" target="_blank">S2 Table</a>.</p

Tepezmaite cycads.

a) Ceratozamia brevifrons with female cone; b) C. morettii with male cone; c) C. tenuis with female cone.</p

Relationship between: number of floral visitor species (A); network specialization (<i>H</i>_<i>2</i>’) (B); interaction diversity (C); nestedness (NODF-metric) (D); modularity (M-metric) (E); number of visitor species found in the central core of highly generalist species (F), and the log₁₀-transformed fragment size of six fragments in Los Tuxtlas, southeast Mexico.

<p>Regression correlation coefficient (<i>r</i>) and significance (<i>p</i>) computed using simple linear regressions are also shown.</p

Individual-based networks involving individuals of <i>Astrocaryum mexicanum</i> (Arecaceae) and their effective (EP) and non-effective (NEP) pollinators in six tropical rainforest fragments (2, 4, 19.4, 34.6, 114.6 and 700 ha respectively) of Los Tuxtlas, southeast Mexico.

<p>The right nodes represent different individuals of <i>A</i>. <i>mexicanum</i> considering both (M) male- and (F) female-phase inflorescence. The left nodes correspond to species of floral visitors that interact with plant individuals. Lines indicate interactions between the two trophic levels. Networks were ordered by both number of links and interaction frequencies. Rectangle height is proportional to the number of interactions recorded per species. Different line lengths indicate the frequency of interactions.</p
