Crossing species' range borders: interspecies gene exchange mediated by hybridogenesis

Crossing species' range borders: interspecies gene exchange mediated by hybridogenesis.

The distribution of species is limited by their ability to adapt to local environments. For adaptation by selection, genetic variability is crucial. As founder effects reduce genetic variability, extension of species' range borders is usually slow due to the reduced probability of successful colonization. However, the range limit might be extended by incorporating locally adapted genes. In west...

Crossing Borders

As emergency physicians, we are privileged to be in a field that crosses more boundaries than any other medical specialty. It is a calling. Our skills are portable and transferable across cultural and geographic disparities. For these reasons, many of us are drawn to sharing our knowledge and training across the globe – towards treating patients in underserved and austere environments abroad. T...

Crossing Borders:

"Cultural systems are coherent patterns of understanding built from the reciprocal relationships among 1) knowledge or beliefs: the shared conceptual understandings of what or how things are; 2) patterns of practice: both the models for doing and the model-guided, habituated actions of everyday practice; 3) 3 tools and artifacts: the means and ends of practical action; and 4) patterns of affect...

Crossing Borders for Science

Exchanging ideas with like-minded, enthusiastic people interested in the same topic is crucial for the advancement of a scientist's career. Several Regional Student Groups (RSGs) of the International Society for Computational Biology (ISCB) Student Council have cooperated in the last six years to organize scientific workshops and conferences. With motivated students, it is possible to create a ...
