The timing of events determines rates and constrains models of evolution. The environmental context can relate the The prefix allo-means "other". When paired with the suffix -patric, meaning "place", it becomes clear that allopatric is a type of speciation caused geographic isolation.The individuals that are isolated are literally in an "other place". The most common mechanism for geographic isolation is an actual physical barrier that gets between members of a population. Gram staining: differentiates bacteria into two types Gram positive and Gram negative bacteria The superoxol catalase test used for the presumptive speciation of certain cases only X-linked pattern was described without description of genetic locus.

Some lakes, despite being old, have gone through a series of major environmental events, and the re-spective endemic species are often comparable young, as ob-served in Lake Malawi (e.g., Schulthei� et al., 2009, 2011) An examination of species within the genus Surirella from the Malili Lakes, Sulawesi Patterns and Processes of Speciation in Ancient Lakes, 215-224, 2008.

Details of speciation have been inferred for approxi- mately one in every 300 000 meta- zoans, but this ratio is much higher in ancient lakes2. Speciation pro- cesses are generally inferred from extant patterns, but ancient lakes also allow for a wide variety of ex- perimental approaches^.

The first scenario is predicted if divergent selection on color pattern had not often caused speciation, and color pattern types, once evolved in During recent decades, speciation in ancient lakes has emerged as an important and exciting topic in evolutionary biology. The contributions in this volume deal with patterns and processes of biological diversification in three prominent ancient lake systems. Speciation in the Cladophorales species flock of ancient Lake Baikal challenges in evolutionary biology as many of the processes involved in speciation, as well patterns of genetic variation and structure that suggest different reproductive Allopatric speciation is where new gene pools arise out of natural selection in In FY2014 we continued work on network models of spatial biodiversity processes, and applications to with the theory of island biogeography to describe the patterns of biodiversity they Insular lake biogeography using freshwater mollusks. Ancient lake. Ancient lakes continue to persist due to plate tectonics in an active rift zone. This active rift zone creates lakes that are extremely deep and difficult to naturally fill with sediment. Due to the prolonged life of ancient lakes, they serve as models for isolated evolutionary traits and speciation. Ancient lakes are exceptional freshwater environments that have continued to exist for hundreds of thousands of years. They have long been recognized as centres of biodiversity and hotspots of evolution. During recent decades, speciation in ancient lakes has emerged as an important and exciting topic in evolutionary biology.
