Do Orientation-Based Differences in Nestbox Temperature Cause Differential Ectoparasite Load and Explain Patterns of Nest-Site Selection and Offspring Condition in Great Tits?

Table 2

GLMM analyses of ectoparasite abundance (divided into quartiles) and great tit offspring quality (𝑛=93 chicks in 20 nests).
