Host Longevity and Parasite Species Richness in Mammals
Hosts and parasites co-evolve, with each lineage exerting selective pressures on the other. Thus, parasites may influence host life-history characteristics, such as longevity, and simultaneously host life-history may influence parasite diversity. If parasite burden causes increased mortality, we expect a negative association between host longevity and parasite species richness. Alternatively, i...
متن کامل(macro-) Evolutionary ecology of parasite diversity: From determinants of parasite species richness to host diversification
The present review summarized the factors or determinants that may explain parasite diversity among host species and the consequences of this parasite diversity on the evolution of host-life history traits. As host-parasite interactions are asymmetrical exploited-exploiter relationships, ecological and epidemiological theories produce hypotheses to find the potential determinants of parasite sp...
متن کاملHost specificity of parasite manipulation
Recently we presented how Camponotus ants in Thailand infected with the fungus Ophiocordyceps unilateralis are behaviorally manipulated into dying where the conditions are optimal for fungal development. Death incurred in a very narrow zone of space and here we compare this highly specific manipulation with a related system in Brazil. We show that the behavioral manipulation is less fine-tuned ...

متن کاملThe Magnitude of Local Host Specificity for Phytophagous Insects and its Implications for Estimates of Global Species Richness
Estimates of the global number of arthropod species range from 2 million to more than 30 million species. One of the most critical assumptions affecting the higher of these estimates is the assumed magnitude of host specificity of phytophagous insects, which varies considerably. Difficulties in estimating this value are caused by both lack of satisfactory data sets and lack of methods for its o...
