| condition-specific competition governs the geographic distribution and diversity of ectoparasites. | understanding how environmental parameters interact to govern species distributions is a shared goal of ecology and biogeography. biotic and abiotic conditions can change distributions by affecting the nature of interspecific interactions. although documented in free-living systems, this context dependency has been neglected in parasite interactions. we investigated the influence of condition-specific competition on the specificity of two species of feather lice (phthiraptera: ischnocera) that s ... | 2011 | 21460573 |
