But small, endangered populations are often genetically depleted, and the acquisition of beneficial de novo mutations often takes too long when population face quick and extreme environmental change.

2. Next-generation Molecular Systematics and Evolution: insights into Medicago
Abstract : Evolutionary relationships among species have in recent years been inferred using DNA sequences from specific genes and represented by tree diagrams (phylogenies). However, the signal contained in different genes can produce conflicting sets of relationships – i.e., gene tree incongruence. READ MORE

3. Crossing barriers: Genetic consequences of translocating wild cleaner fish for aquaculture
Abstract : Several species of fish show a symbiotic cleaning behaviour, where they assist other species by feeding and removing dead skin or ectoparasites. Some of these cleaner fish species are used as a low-cost parasite control in salmon aquaculture, often considered to be more environmentally friendly than other delousing methods. READ MORE
