From: Snowmelt and laying date impact the parental care strategy of a high-Arctic shorebird
Relationships between parental care strategy (0 = Biparental, 1 = Uniparental), laying date, nest relative abundance, and their explanatory variables presented in the path diagram (Table 1; Fig. 2; n = 149 nests). Colours used in the panels refer to the different categories of hypotheses: yellow = social environment hypotheses, green = ecological factors, pink = predation. For panels presenting significant relations, the prediction of the fitted model, as modelled with the path analysis, is presented by a full line, with the shaded area representing the 95% confidence interval around the model prediction. These confidence intervals indicate the degree of certainty in the predicted relationships: narrower intervals suggest more precise predictions, while wider intervals reflect greater uncertainty. The significant positive slope in panel A shows how later laying dates increase the probability of uniparental care, while the significant negative slope in panel B demonstrates how delayed snowmelt decreases the probability of uniparental care (increases biparental care). Axes for significant relations show bold lines.
