Buitenkansje voor de liefhebber van zowel natuur als kunst: 'The Dutch Drawings in the Teyler Museum.' Werkelijk een prachtig boek, maar helaas, helaas zit er een pagina los, vandaar dat het van €59,95 afgeprijsd is naar €19,95.

The lake sturgeon (a 100-year-living, 90-kg relic from the age of dinosaurs) is returning to Missouri’s rivers after near-extinction from dams and pollution. The revival of a keystone species and signalling broader recovery of the Mississippi basin’s river systems.

1/🧵 Over the past decade, misinformation in the popular media & the opinion pages of some journals has promoted the claim that concern over species invasions is overblown, because "most invasions do not cause extinctions".

Here is a brief reminder of what scientific evidence shows...

I have my Vertebrates students read excerpts from Jane Goodall’s field notes as great examples of natural history observations that can lead to asking important research questions & discoveries. Passion for the natural world, attention to detail, & a curious mind are a powerful combination. RIP🦍 🦧 🐒
Jane Goodall, primatologist and ambassador for wildlife, dies at 91 — National Geographic
Through her groundbreaking work with chimps in Africa, Goodall helped people understand that animals are sentient and intelligent.

With the PhD application process looming (at least in the UK), here’s an interesting article on why you may want to consider research outside of marine mammals (we know! shock horror!) and why this doesn’t have to be the end of a career in marine mammal science 🐬

I can’t find a PhD on marine mammals. What now?
Finding a PhD on marine mammals is no easy task, and not everyone succeeds. But your dreams of doing marine mammal research did not end...
