Land cover classification of the city.

<p>Land cover vectorial obtained after a non-supervised classification of the NDVI raster image. Sand-fly sampling sites are represented by the ▲ symbol. Areas of 50 m radius around the trap were used to calculate each type of cover proportion.</p

Spatial distribution of the proportion of dogs and sandfly.

<p>Spatial distribution of the proportion of rK39+ dogs (a) and sandfly accumulated abundance (b). Circle size represents the arbitrarily categorized values of the proportion of rK39+ dogs, and abundance of <i>Lu</i>. <i>longipalpis</i>, respectively. In parenthesis, number of sampling sites are indicated.</p

Nucleotide divergence (<i>Da</i>) of the ND4 fragment measured as the number of net nucleotide substitutions for <i>Lu</i>. <i>longipalpis</i> haplogroups (see Results) using the Jukes and Cantor correction (below diagonal), and pairwise F_ST comparisons between haplogroups (above diagonal).

Median-joining haplotype network of the <i>Lu</i>. <i>longipalpis</i> complex based on 261 nucleotides of the 3´ region of the cyt <i>b</i> gene.

<p>The circle size corresponds to the frequency of each haplotype. Intermediary haplotypes (missing intermediate haplotypes) are shown as red circles. Each line connecting haplotypes represents one mutational step, whereas numbers along the lines are total number of mutational steps between haplotypes. Colours indicate: orange = Clorinda; fuchsia = Corrientes city; turquoise = Puerto Iguazú; grey = San Ignacio; pink = Santo Tome; purple = Tartagal; white with blue outline = Venezuela; green = Brazil.</p
