Burung wren kecil di pulau-pulau terpencil Skotlandia tumbuh jauh lebih besar daripada kerabat mereka di daratan utama dan mengembangkan ciri-ciri khas yang dapat mengarah pada spesies baru.

Para peneliti di University of Birmingham mempelajari empat populasi burung wren yang terisolasi di Skotlandia, termasuk yang berada di Shetland, Fair Isle, Outer Hebrides, dan St Kilda. Burung-burung di St Kilda saat ini memiliki berat antara 13 hingga 16 gram, dibandingkan dengan 7 hingga 10 gram untuk burung di daratan utama Inggris. Burung wren St Kilda terbesar memiliki ukuran dua kali lipat lebih besar daripada spesimen terkecil di daratan utama.

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.
