Lake research offers clues to managing crayfish invasions

...exist among lakes. In other words, they can either dominate or be a minor influence. This can happen, he adds, because of the interaction among fish, their habitat and rusty crayfish. When the crayfish population is small, Roth explains, there tend to be more fish, which feed heavily on the baby crustaceans a...

Save the rainforest - eat a tree

...dings mean red clay tree species would grow on and dominate both habitats red clay soils and white sand soils were it not for the presence of insects that normally prevent the red clay tree species from living on white sand soil. "My results suggest that if bugs weren't around, the faster-growing clay...

Digital evolution reveals the many ways to get to diversity

.... Once they run low on resources, their ability to dominate loses steam and other hard-working organisms have a chance to get a foothold in the habitat. Ofria, an MSU assistant professor of computer science and engineering and one of the paper's authors, gives the example of an ambitious organism that eats gl...

...single language by 2050? If so, what language will dominate once a universal tongue emerges? "Language death" ishappening at a rapidly accelerating pace, and some researchers predict that up to half the world's more than 6,000 languages may vanish during the 21st century. How does language death occur, and wh...

New study finds evolutionary diversification in Hawaiian spiders

...ities on a continent and evolutionary process that dominate community formation in the Hawaiian Islands. "This study suggests that the process of community assembly - the way niches are filled by a set of co-adapted species - is governed by universal principles," she said.

Araucariaceae of New-Caledonia: endemic species in danger

...ions. In the forest, the Araucaria and the Agathis dominate the high ground and regrowth only develops with the help of gaps caused by clearances, which indicates heliophilous affinities (3) of the two genera. This state-of-the-art review of knowledge on the Araucariaceae could provide keys to a better unde...

With the genomes in hand, researchers will have a better idea of how to solve mysteries surrounding these organisms, such as how they thrive in the nutrient-poor open ocean. For the Palenik-led paper, contributors in...

Cooperation between unrelated male lizards adds a new wrinkle to evolutionary theory

In the new study, Sinervo and Clobert found that blue males tend to establish territories in close proximity to other blue males. Furthermore, DNA analysis showed that neighboring blue males are more similar genetically than would be...

Difficulties with primate cloning: A religious comment

Reproductive cloning just isnt very likely, and anyone who exploits public fears of cloning to stop medical research is not treating the public with honesty and respect.

Black Spruce grow the slowest, but eventually out-compete the Aspen and Jack Pine by blocking the sunlight available to these species. By 70 years following a burn, these forests are dominated by Black Spru...

The hybrid seeds were also preferred by birds and other organisms that fed on the seeds, making the chances for these plants to reproduce successfully even lower. The amount of the ...

The researchers found that although the relationship between these invaders is complex, one fact is simple. The successful species is often the one that gets there first, noti...
