Minimum habitat thresholds required for conserving mountain lion genetic diversity

Conserving Genetic Diversity in Rainbow Trout

Conserving genetic diversity is a major concern for north temperate fauna which are species poor but rich in genetic diversity. The problem is believed to be especially serious for freshwater fish where populations are isolated by barriers to migration. Isolation and low species diversity have been hypothesized to be the key ingredients in an adaptive radiation that has taken place in British C...

Population Demography and Genetic Diversity in the Pleistocene Cave Lion

Characterized by considerable climatic instability, the Pleistocene was a time of changing ecological conditions that affected both plant and animal life. Glacialinterglacial cycles were irregular and created contrasting landscapes and environments in many regions over time (Hofreiter and Stewart, 2009). These regional and global changes had a profound impact on animal populations, resulting in...

Genetic Diversity, Habitat Fragmentation and Epigenetic Variations

Evaluation of Genetic Diversity of Papaver bracteatum Lindl. Populations in Alborz Mountain Using SCoT Molecular Markers

Background: Iranin poppy (Papaver bracteatum Lindl.) belongs to Papaveraceae family which has important alkaloids such as thebain. Objective: Investigation of genetic diversity and population structure of Iranian poppy populations from Alborz Mountains. Methods: Total DNA from 36 genotypes (12 individuals from each population) were extracted by doyle method. Thebaine of capsules were assayed...

Conserving Phylogenetic Diversity Can Be a Poor Strategy for Conserving Functional Diversity.

For decades, academic biologists have advocated for making conservation decisions in light of evolutionary history. Specifically, they suggest that policy makers should prioritize conserving phylogenetically diverse assemblages. The most prominent argument is that conserving phylogenetic diversity (PD) will also conserve diversity in traits and features (functional diversity [FD]), which may be...
