Figure 1From: History and complexity in tick-host dynamics: discrepancies between ‘real’ and ‘visible’ tick populationsHost-related influences on ‘real’ and ‘visible’ tick populations (see text for definitions). Legend: Factors beneath the plus (+) sign act to increase populations, whilst those under the minus (-) sign act to decrease populations. Pale shading denotes instar N, darker shading instar N + 1.Back to article page
