Fig. 4 in The ectoparasites of hybrid ducks in New Zealand (Mallard x Grey Duck)

Fig. 4. Tanglegram showing the associations between the CO1 gene trees for the host ducks (on the left, n = 15) and the three species of louse (on the right, n = 61) from Manawatu, New Zealand. For lice, only the different haplotypes are shown. The two hosts with Grey Duck mtDNA are shown in bold as well as the louse haplotypes exclusive to them. Thin lines indicate host–parasite associations. Lice photos are illustrative and not to scale.

Fig. 3. Bayesian phylogeny of Anaticola crassicornis based on 378 bp of CO1 gene from Escalante et al. (2016) but with the addition of 16 new sequences from New Zealand hosts. The values above branches are posterior probabilities. The scale bar indicates nucleotide substitutions per site along the branch lengths. Haplotypes names correspond to those shown in Fig. 2. For simplicity we are showing the portion of the tree of interest, the full tree with all downloaded sequences can be found in the Supplementary Fig. S2. NZ = New Zealand.

On the right, unrooted parsimony networks for the 40 hybrid host ducks showing the relationships of CO1 haplotypes (top) and control region (bottom). The areas of the circles are proportional to the number of haplotypes observed. The capital let- ters indicate the different haplotypes found.

Fig. 1. Ectoparasite abundance on Mallard x Grey Duck hybrids in New Zealand. Histograms of A) total lice load; B, C, D) abundance per host for each of three feather lice species, with the phenotypic-hybridisation level of each duck shown in different colours. For representation purposes, ducks were considered to be Grey Ducklike for principal component 1 (PC1) score below −1.5, intermediate for a PC1 score between −1.5 and 1.5 and Mallard-like for a score above 1.5.

Sea duck network analysis dataset

This data file consists of habitat centroids used to construct network models for sea ducks in Eastern North America and is associated with the manuscript "Spatially-explicit network analysis reveals multi-species annual-cycle movement patterns of sea ducks" published in Ecological Applications. Columns are organized as follows: id - unique identifier species - species from which the centroid was obtained (BLSC = black scoter, COEI = common eider, LTDU = long-tailed duck, SUSC = surf scoter, WWSC = white-winged scoter) stage - period of the annual cycle to which the centroid belongs (W = winter, B = breeding, S = spring staging, M = fall staging and molt, WM = winter migration, BM = breeding migration, MM = molt migration, SM = spring migration) site - position of centroid within season (i.e., W1 = first site occupied during winter, W2 = second site occupied, etc.) cycle - number of annual cycles following transmitter attachment (1 = first cycle after attachment, 2 = second cycle after attachment, etc.) sex - sex of individual (M = male, F = female) age - age of individual (HY = hatch year, SY = second year, TY = third year, ASY = after second year, ATY = after third year, AHY = after hatch year capture_reg - general area where individual was captured capture_subreg - specific region within capture region where individual was captured lon - longitude of centroid lat - latitude of centroid duration - number of days spent at centroid start - date of arrival at centroid end - date of departure from centroid jstart - Julian date of arrival at centroid jend - Julian date of departure from centroid season - season of annual cycle in which centroid occurred (W = winter, F = fall, B = breeding, S = spring) year - calendar year in which centroid began to - node in which centroid is grouped from - node in which previous centroid is grouped (i.e., node in which indiviual was located before moving to present node) to_sea - season of annual cycle in which centroid occurred from_sea - season of annual cycle in which previous centroid occurred type - movement type to centroid; the first letter represents the season (coded as in "season" column), and the second represents the nature of the movement (WD = dispersal within a season, M = migration among seasons) type2 - same as "type", but with dispersal movements coded by the stage in which they occur (W = winter, B = breeding, SM = spring migration, WM = winter migration) count_ind_sp - total number of tracked individuals of the species represented by centroid weight - base centroid weight (all centroids equal, deployments excluded) wt_sp - species-adjusted centroid weight: for centroid x in species i, weightx = (N centroidstotal) × (N centroidsi)-1 wt_dur - duration-adjusted centroid weight: for centroid x, weightx = (days at centroid location) × 365-1 wt_sp_sex - species-and-sex-adjusted centroid weight: for centroid x, species i, and sex s, weightx = (N centroidstotal) × (N individualsis)-1 wt_ind -  individual-adjusted centroid weight: for centroid x in individual j, weightx = (N centroidsj)-1 wt_ind_sp - individual-and-species-adjusted centroid weight: for centroid x, individual j, and species i, weightx = (N centroidsj)-1 × (N individualsi)-1
