The selective forces driving these patterns may include the concurrent increase in dissolved organic matter or the diversification of spongivorous fishes that required chemical defenses produced by the symbiotic microbial communities. These results show that HMA holobionts are characterized by increased endemism, metabolic dependence and chemical defenses. Additionally, HMA symbioses show a clear signal of phylosymbiosis that is driven by co-diversification of host and microbial symbionts. Conversely, HMA symbioses, consisting of more specialized microbes, have evolved multiple times, but only since the origin of coral reefs. This study shows that the LMA/HMA dichotomy, widely applied across an exhaustive sampling of Caribbean sponge biodiversity, predicts that the LMA symbiotic state is the ancestral state among sponges. These sponge communities have been classified as low microbial abundance (LMA) or high microbial abundance (HMA) for many sponge species, but the evolutionary dynamics of these symbiotic states remains unknown. Symbiotic microbial communities of coral reef sponges serve critical functions that have shaped the evolution of these ecosystems since their origins. Surveying sponge biodiversity across the Caribbean, the authors show that low microbial abundance is the ancestral symbiotic state, whereas high microbial abundance has evolved multiple times and exhibits increased endemism, metabolic dependence and chemical defences. The selective forces driving these patterns may include the concurrent increase in dissolved organic matter in reef ecosystems or the diversification of spongivorous fishes. These results indicate that HMA holobionts are characterized by increased endemism, metabolic dependence and chemical defences.
Additionally, HMA symbioses show stronger signals of phylosymbiosis and cophylogeny, consistent with stronger co-evolutionary interaction in these complex holobionts. Conversely, HMA symbioses, consisting of more specialized microorganisms, have evolved multiple times by recruiting similar assemblages, mostly since the rise of scleractinian-dominated reefs. This study examines the LMA/HMA dichotomy across an exhaustive sampling of Caribbean sponge biodiversity and predicts that the LMA symbiotic state is the ancestral state among sponges. Symbiont abundance varies tremendously among sponges, with many species classified as either low microbial abundance (LMA) or high microbial abundance (HMA), but the evolutionary dynamics of these symbiotic states remain unknown. Several new community oriented features, game modes and online functionalities will also be announced later.Īll in all, RACE 07 features more than 300 cars in 9 different classes on 32 real life racing tracks and city circuits from all over the world.Symbiotic microbial communities of sponges serve critical functions that have shaped the evolution of reef ecosystems since their origins. RACE 07 comes with a score of new tracks and added track variations including several new city tracks, alternate track layouts and reversed track option. The highly detailed damage system is also adapted to give the Formula cars the vulnerability they have in real life.
To support these new race classes the player will be offered the choice between one- or two-race-format. Race with the incredibly fast Formula 3000, Formula BMW and in addition also the Radical sports cars with the models SR3 and SR4.

The game also features the full WTCC season of 2006 which was included in the games predecessor RACE - The WTCC Game, released in 2006 on PC.įor the first time ever SimBin is also presenting single seater action with Formula cars. RACE 07 - The Official WTCC Game features the full FIA WTCC season of 2007 including all cars and tracks, as well as several new support classes and tracks from all over the world.
