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!

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.

#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

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.

"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."
E.g. less 🦈-> more 🦭 -> less 🐧...

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.

#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.

New paper from Lisa Hildebrand at #OregonStateUniversity.
The loss of kelp forests means lower populations of the zooplankton who live there. The #zooplankton are food for migrating #graywhales
