Pequenas carriças em ilhas remotas da Escócia estão crescendo muito mais do que seus parentes do continente e desenvolvendo características distintas que podem levar a novas espécies.

Pesquisadores da Universidade de Birmingham estudaram quatro populações isoladas de carriças na Escócia, incluindo as de Shetland, Fair Isle, Hébridas Exteriores e St Kilda. As aves de St Kilda pesam agora entre 13 e 16 gramas, em comparação com 7 a 10 gramas das aves do continente britânico. As maiores carriças de St Kilda têm mais do que o dobro do tamanho dos menores espécimes do continente.

Researchers at the University of East Anglia have found that Seychelles warblers with closer social ties share more similar gut microbes, particularly anaerobic types spread through direct contact. The study on Cousin Island suggests social interactions drive this microbial exchange. Similar effects likely occur among humans living together.

Aggressive green wall lizards eliminate ancient color variants

Researchers have discovered that aggressive green wall lizards, dubbed 'Hulk' lizards, are rapidly outcompeting and eliminating yellow and orange color morphs that coexisted for millions of years. The common wall lizard, Podarcis muralis, across the Mediterranean now shows only white-throated individuals in many populations. A study analyzing over 10,000 lizards revealed this shift in evolutionary dynamics.
