Darwin’s finches theory challenged
New research suggests that the link between beak morphology and feeding ecology may not entirely explain beak variation evolution. Although a link between feeding ecology and beak morphology was identified, variations may also be influenced by other functional trade-offs, such as singing, preening and fighting.
Diversity boosts coral health
Marine Biologists have demonstrated that lower coral species richness alone can suppress the growth and survivorship of multiple species of corals, under field conditions. The findings highlight the positive role of biodiversity in the function of coral reefs, and how coral species loss may trigger further ecosystem decline.
Microplastics in Marine Mammals
Fifty individuals from 10 species of marine mammal that have washed-up in Britain contained microplastics. Over 80% of the microplastics found consisted of synthetic fibres, typically originating from clothes, fishing nets and toothbrushes. Although found in relatively low concentration, the impact of microplastics of marine megafauna is not yet understood.
