Abstract:
... To explore the environmental adaptation strategies of high-altitude breeding birds to alpine regions, we studied the breeding ecology of the Snow Partridge (Lerwa lerwa) in the Qinghai-Tibet Plateau. Incubation behavior was determined using data loggers in Basu County (2018) and Cuona County (2019), in the Tibet Autonomous Region, China. We monitored seven Snow Partridge nests; clutch sizes ranged ...

Abstract:
... In organisms with complex life cycles, the various stages occupy different habitats creating demographically open populations. The dynamics of these populations will depend on the occurrence and timing of stochastic influences relative to demographic density dependence, but understanding of these fundamentals, especially in the face of climate warming, has been hampered by the difficulty of empiri ...
