Great article by Kaifu and colleagues on early Homo floresiensis: dwarfism evolved in about 300 thousand years. Reminds me of dwarf elephants, where we found similar rates of dwarfism 🏝️⌛️#islands #rapid_evolution https://t.co/3u5wOZMh9W

well-said: "the final populations of all moa species persisted in suboptimal habitats in cold, mountainous areas that were generally last and least impacted by people". This applies to all remaining insular endemic species, not only flightless birds 😢#vulnerable #extinction_risk

📢What would happen if threatened mammals became extinct on 🏝️islands? We looked into the consequences of species extinctions on the functional space of islands worldwide. More details below, but you can read the full paper published today @GlobalChangeBio https://t.co/OQisxFsAgW

Dit is Geertruida van der Berg uit Geertruidenberg, de eerste Nederlandse vrouw die zonder begeleiding van haar vader of echtgenoot over straat mocht fietsen. De vrouwenfietswet van 1 juli 1910 wordt beschouwd als een mijlpaal binnen de feministische geschiedenis van Nederland.

I was just thinking someone needs to write a paper saying it is not biodiversity per se, but *species interactions*, that underpin ecosystem services This new paper makes that point, although I think there is much more to say on the subject https://t.co/hNOEH51qgV

Have you ever seen the ring-tailed vontsira? Found in the forests of Madagascar, this carnivore weighs ~2 lbs (900 g) and feeds on insects, eggs, fish, small mammals, and more. The ring-tailed vontsira is an agile critter, an excellent climber, and is known to be playful.
