Fungi are the rainforest ‘diversity police’

A new study has revealed that fungi, often seen as pests, play a crucial role policing biodiversity in rainforests.

The research, by scientists at Oxford University, the University of Exeter and Sheffield University, found that fungi regulate diversity in rainforests by making dominant species victims of their own success.

Fungi spread quickly between closely-packed plants of the same species, preventing them from dominating and enabling a wider range of species to flourish. (more…)

Researchers at the University of Exeter found that older male burying beetles make better fathers than their younger counterparts.

The study found that mature males, who had little chance of reproducing again, invested more effort in both mating and in parental care than younger males.

The study, published in the journal Proceedings of the Royal Society of London – B, considered how the likelihood of paternity influenced the way that males cared for young. Older males were good fathers and looked after the young even when they were unsure whether the offspring were theirs. Younger males, who had a higher chance of reproducing again, tended to care less for offspring, particularly when they were uncertain of their paternity. (more…)
