Restoring the balance of nature to #Yellowstone's #ecosystem was achieved by reintroducing #graywolves to the region. Just think how robust this locale would be if the wolves had never been eliminated in the first place!

Unmasking the Sea Star Killer After a decade of carnage, we finally know what’s devastating sea stars along North America’s West Coast. Does that mean scientists can save them?

Caught between joy at the high quality scientific investigation and sadness at the benthic devastation that's unfolded over on the North American Atlantic coast. Sometimes I wish ecological theory was just theory. #trophiccascade #regimeshift

One of the classics of NZ ecological science is this Auckland study by Sandra Anderson and colleagues. They showed, in extraordinary detail, how the loss of two endemic flower-pollinating birds from mainland Auckland (korimako and hihi), and the relative rarity […]

Wolves heal ecosystems. 🐺🌿

Their return triggers a trophic cascade, helping plants regrow, rivers stabilize, and wildlife thrive. Predators matter.

“Without these apex predators to regulate populations, we are seeing measurable changes that could have long-term effects on ocean health. ” -- Neil Hammerschlag, lead author of the study.

Dynamic and context-dependent keystone species effects in kelp forests | PNAS Sea otters are an iconic keystone predator that can maintain kelp forests by preying on grazing invertebrates such as sea urchins. However, the eff...

#Seaotter introduction and #kelp forest recovery is a textbook-favorite example of #trophiccascade. New research tries to explain why the effect is not consistent in strength

New paper in Communications Biology from Mark Meekan suggests the removal of mesopredators (such as #sharks) from a reef may cause a #trophiccascade that results in more #crownofthorns #starfish

Rat poison threatens Italy’s growing wolf population More than half of dead wolves in study had been exposed to rodenticides

Rodenticides don’t stop at rats they move up the food chain poisoning predators like Italy’s growing wolf population. A silent but deadly threat to ecosystems. Unintended consequences? No. Just reckless disregard.

#TrophicCascade

2024 study highlights the threat, contextualizing recent events.

‘Awe-inspiring and harrowing’: how two orcas with a taste for liver decimated the great white shark capital of the world A decade ago, up to 1,000 of the apex predators lived in one South African bay. Now they have gone, fleeing from killer whales. But the gap they have left creates problems for other species

#ecology

"This explosion of prey species could represent what ecologists call a #trophiccascade, where the loss of a predator reverberates down the food chain, unbalancing the ecosystem."

If a wolf howls in the forest and noone is there to hear it, does it still restore the ecosystem? 🫡Yes. Always yes! #TrophicCascade #ConservationEcology

The new (to me) information is the strong #citsci component of this research; part of the data came from an #ecotourism operator with detailed daily records of customer otter observations going back 15 years.

New research says gray whales in Oregon are in trouble Gray whales in Oregon love to forage in our kelp forests but these areas are struggling. Perhaps, bringing back another marine mammal to our shores could be the solution they need.

#trophiccascade

The textbook Marine example of a trophic cascade:
1 Otters eat the urchins
2 Kelp survives the urchins
3 Zooplankton has kelp for us to grow in
4 Gray whales have food

🦑 #Marinescience #whales #kelp

Further coverage of #graywhales moving further from the $Oregon coast. Why? A #trophiccascade that means there's less zooplankton to eat

Excess urchins = less kelp
Less kelp = less plankton
Whales go where the food is

Sorry to see that my belief that #wolves reversed ecological changes in Yellowstone Park may not be grounded on good evidence... #trophiccascade. This #natgeo article cites exptl work by Hobbs et al 2024.

Without keystone predators like sea otters & sunflowers stars, sea urchins can destroy kelp forests. New study suggests this reduces zoplankton that live in kelp, an important food for gray whales.
