Seasonal epidemiology of gastrointestinal nematodes of cattle in the northern continental climate zone of western Canada as revealed by internal transcribed spacer-2 ribosomal DNA nemabiome barcoding

Table 3 Results of multiple linear regression on the number of L3 recovered from the grass surrounding fecal pats in relation to climate variables for the two main nematode species found in the study, Cooperia oncophora and Ostertagia ostertagi

	C. oncophora		O. ostertagi
	Regression coefficient	P-value	Regression coefficient	P-value
Mean temperature 3 weeks before sampling	− 0.0215	0.540	− 0.0317	0.019*
Total precipitation 3 weeks before sampling	− 0.0117	0.897	− 0.0116	0.105
Total precipitation 1 week before sampling	0.02326	0.008***	0.01631	0.005**
Days after egg deposition²	− 0.00039	0.006***	− 0.00044	< 0.001***
Intercept	5.215		5.790
R² (R² adjusted)	0.63 (0.6)		0.51 (0.46)

Mean temperature in the 3 weeks prior to sampling was also included, but its effect was not significant
