Table 1 Least squares 99% confidence intervals (means ± half amplitude of 99% CI) for the total length and sheath tail length (in μm) of infective larvae of L. douglassii and L. dentatus at different Brazilian regions (origin of samples as described [4, 6]) and Libyostrongylus sp. from Ethiopia

From: First record of the nematode Libyostrongylus dentatus Hoberg, Lloyd & Omar, 1995 (Trichostrongylidae) in ostriches (Struthio camelus Linnaeus, 1758) (Struthionidae) outside the Americas

  1. aP-values for contrasts (adjusted Tukey-Cramer) between Brazilian species split within regions (within the same row) for both total length and sheath tail length, e.g. L. douglassii vs L. dentatus within Paraná 1 region, and so on. P < 0.02 indicate statistical significance
  2. bP-values for contrasts (adjusted Tukey-Cramer) between Brazilian L. dentatus and Libyostrongylus sp. from Ethiopia within the respective region for both total length and sheath tail length, e.g. Brazilian L. dentatus vs Ethiopian Libyostrongylus sp. within Paraná 1 region, and so on
  3. Abbreviations: df degrees of freedom, L. sp. Ethiopian Libyostrongylus sp.
