Important insights into impacts of tropical cyclone: “The results were striking. Risks of dying from various causes consistently increased after a tropical cyclone. Generally, the risk peaked within the first two weeks of the cyclone, followed by a rapid decline”

theconversation.com/we-studied-2...
We studied 217 tropical cyclones globally to see how people died. Our findings might surprise you
Tropical cyclones can be even more deadly – and for a wider range of reasons – than we ever thought.

Ecology Matters: Conversations with Australian Ecologists

Australia’s ecologists share why nature matters across 30 essays with stunning photos – from ants & Antarctic mosses, to wallabies & waterways, to frogs & fungi. www.publishing.csiro.au/book/8205

@ecolsocaus.bsky.social
Ecology Matters
Australia is known for its spectacular and diverse natural environment, from sweeping landscapes to unique flora and fauna. It is a place that invokes wonder and demands protection in equal measure. Its ecology matters, as do the people who have dedicated their careers to understanding it – ecologists. But what do ecologists do? How do they end up studying strange and obscure species? What is it like to work in remote and unusual environments? What happens when disaster strikes? And what are their hopes and concerns for the future? In Ecology Matters, Australia’s preeminent ecologists explain why nature truly matters across 30 enlightening essays. Learn about crayfish and climate change, seed banks and seagrass restoration, floods and fire ecology, ants and Antarctic mosses, whales, waterways and wallabies, and frogs, feral cats and fungi. Featuring interviews with students, Indigenous rangers, restoration ecologists and leaders in the field, this collection of conversations spans the breadth and diversity of Australian ecology. Accompanied by spectacular images from around Australia, many captured by ecologists in the course of their work, Ecology Matters showcases a unique perspective of Australian nature.

Can you spot the lifer (new bird seen in one’s life) I saw in my neighbourhood this morning tiptoeing through the reeds? It’s a pale-vented bush-hen enjoying the post-storm puddles everywhere .. fortunately my partner recognised its loud call #BirdWatching #wildoz #qld
Tall green reeds in most of image but in the centre is the dark brown head with dark eye and yellow-olive bill with vermillion patch on top. Body just visible of a secretive pale-vented bush-hen with pale yellowish legs barely visible among the reeds. Bird has a loud piping call but is not often seen in the open.

Up to 59% of Antarctic ice shelves may be at risk of disappearing under high-emission scenarios by 2300, according to an analysis of the effect of ocean warming in Nature. This could result in up to 10 m of global sea-level rise. go.nature.com/47Ag4k1 🌊 🧪
This is figure 1, which is a schematic of the processes that contribute to the Antarctic ice-shelf mass balance.

It’s Aussie Bird Count week and this juvenile eastern yellow robin has definitely been counted! She’s part of a long term study and just been banded to help with monitoring and understanding the complex life history of these beautiful birds. #MistNetting #Science #BirdCount #SunshineCoastHinterland
Front view of a juvenile ca. 1.5 month old eastern yellow robin being held by a certified bird bander after being banded with metal and colour band. Yellow breast with greyish mottled head and upper body juvenile plumage. Measurements suggest female bird. Pinkish beak is open as she was squawking right before being released back in her territory near the adults.

Interesting. This says in words some stuff that has bothered me for a long time - like why European and American scientists get to parachute in to research the African fauna that I literally grew up with, but it would seem really odd if I started a project on moose or reindeer.

Agreed.. here’s a follow up pic from my garden where the tawny frogmouth chick managed to mimic the parents cool pose, apart from fluffy belly feathers and only for a short while before relaxing again into a round puffball!

I agree as there’s been ongoing uncertainty whether oysters are carbon positive or negative but if I understand this study it indicates an overall net benefit. My colleagues note they measured marine CO2 removal, which isn’t 1-1 with atmospheric CO2 removal, so there’s hope but still uncertainty
