How are inbreds successful?
Waldir M. Berbel-Filho 

 

Genetic diversity is considered a key factor to fitness and survival on ever-changing environments.  As a consequence, inbreeding is thought to be as an evolutionary dead end. However, several examples of inbred organisms (i.e. asexual/clonal lineages, invasive species, and bottlenecked populations) have been reported to successfully cope with a wide range of environmental pressures. If genetic diversity is a requirement to adaptability, how are inbreds successful?

Biogeography of protists with different forms of acquired phototrophy in the global oceans
Suzana G Leles
There is increasing awareness that many marine protists are mixotrophs, i.e., combine autotrophy and heterotrophy in a single cell. The most praised mixotrophs conform to ‘plants that eats’, but many others are ‘animals that photosynthesize’ through acquired phototrophy. Acquired phototrophy among protists takes place within a gradient from species with lower to species with higher control over the acquired machinery; therefore, differences in their distribution in time and space may be expected. A global analysis of marine protists with different forms of acquired phototrophy revealed that they are ubiquitous in the oceans, with different groups dominating in different regions. This study provides basis to validate future modelling studies addressing mixotrophy within pelagic marine food-webs.
