However, factors that limit species’ elevation range are still poorly understood. We tested McArthur’s hypothesis of elevation range limits in two carrion beetles with distinct life history traits: Nicrophorus nepalensis, a habitat specialist, and Calosilpha cyaneocephal, a habitat generalist. We found that physiological constrains drive the lower and higher elevation range limit of C. cyaneocephal, whereas competition with maggots was found responsible for the lower limit of elevational range of N. nepalensis. Contracting to McArthur’s classic hypothesis, our findings show that different life history traits between species may explain the different constrains in lower elevation range limit: habitat specialists may be more susceptible to biotic factor than habitat generalists. Our study of elevation range limit can help us understand species distribution pattern and better predict the species responses to climate change. Pei-Fen Lee 李培芬 2013 學位論文 ; thesis 55 zh-TW |
