What maintains stability within an ecosystem and prevents a single best competitor from displacing other species from a community? Does ecosystem stability depend upon the presence of a wide variety of species, as early ecologists believed, or does diversity do the exact opposite, and lead to instability, as modern theory predicts?

What maintains stability within an ecosystem and prevents a single best competitor from displacing other species from a community? Does ecosystem stability depend upon the presence of a wide variety of species, as early ecologists believed, or does diversity do the exact opposite, and lead to instability, as modern theory predicts? A new study suggests an answer to this question that has been a subject of debate among ecologists for half a century.
The researchers approached the question of population growth using a model that, so far, had not been used in this context -- though it aligns with conventional wisdom and the way that people have traditionally modelled individual growth . "What's amazing is that such a small difference in population growth can have such a large effect on community interactions, completely reversing the predictions from decades of theory."Their findings raise alarming questions about the potential large-scale impacts of biodiversity loss.

Eight new deep-sea species of marine sponges discoveredDespite marine sponges being widespread on our planet, their biodiversity and distribution is still poorly known. Even though the Mediterranean Sea is the most explored sea on Earth, a study reveals the presence of new sponge species and new records in unexplored habitats such as underwater caves or mountains around the Balearic Islands.
