Lion population dynamics: do nomadic males matter?

Two-sex matrix models in assessing population viability: when do male dynamics matter?

1. While most demographic population models used in conservation rely on female vital rates, recent empirical evidence suggests that male dynamics should be included in population models used for assessing extinction risk. 2. Using California sea lions Zalophus californianus as an applied example, we demonstrate that there are situations in which two-sex models are more appropriate than the com...

Do Workers\' Remittances Matter for the Egyptian Economy?

Workers’ remittances constitute one of the most important sources of external finance for many developing countries. Although it shows a decreasing trend in recent years, Egypt after 1970s with her regular and massive labor migration to abroad has been still one of the gainer countries on remittances across the world. Empirical studies that implemented for various countries reveal workers’ ...

The Evolutionary Dynamics of the Lion Panthera leo Revealed by Host and Viral Population Genomics

The lion Panthera leo is one of the world's most charismatic carnivores and is one of Africa's key predators. Here, we used a large dataset from 357 lions comprehending 1.13 megabases of sequence data and genotypes from 22 microsatellite loci to characterize its recent evolutionary history. Patterns of molecular genetic variation in multiple maternal (mtDNA), paternal (Y-chromosome), and bipare...

Individual Behaviors Dominate the Dynamics of an Urban Mountain Lion Population Isolated by Roads

Large carnivores can be particularly sensitive to the effects of habitat fragmentation on genetic diversity [1, 2]. The Santa Monica Mountains (SMMs), a large natural area within Greater Los Angeles, is completely isolated by urban development and the 101 freeway to the north. Yet the SMMs support a population of mountain lions (Puma concolor), a very rare example of a large carnivore persistin...
