Saltwater crocodiles have rapidly recovered in population due to a dietary shift from marine to terrestrial sources.
Dietary shifts may underpin the recovery of a large carnivore population
Supporting the recovery of large carnivores is a popular yet challenging endeavour. Estuarine crocodiles in Australia are a large carnivore conservation success story, with the population having extensively recovered from past heavy exploitation. Here, we explored if dietary changes had accompanied this large population recovery by comparing the isotopes δ13C and δ15N in bones of crocodiles sampled 40 to 55 years ago (small population) with bones from contemporary individuals (large population). We found that δ13C and δ15N values were significantly lower in contemporary crocodiles than in the historical cohort, inferring a shift in prey preference away from marine and into terrestrial food webs. We propose that an increase in intraspecific competition within the recovering crocodile population, alongside an increased abundance of feral ungulates occupying the floodplains, may have resulted in the crocodile population shifting to feed predominantly upon terrestrial food sources. The number of feral pigs consumed to sustain and grow crocodile biomass may help suppress pig population growth and increase the flow of terrestrially derived nutrients into aquatic ecosystems. The study highlights the significance of prey availability in contributing to large carnivore population recovery.
Supercommunist: What's the name of that species of semi-aquatic crocodylomorph with the unusually long forelegs? Also lol at the previous messages.

Infinity Blade: See, you just proved my point. If you can't be bothered to touch grass, eat ten dicks you terminally online anthropoid smegma stain.

Infinity Blade: I do, however, know that you've spent tons of time profusely apologizing and sweet-talking to Taipan just to get back on Carnivora forum, only to insult him when he didn't. You're not sorry for anything.

Infinity Blade: DM me twice. Pardon me, Hammerhead, if I don't buy your story about why you did it.

Infinity Blade: I don't know how Hammerhead knows things I said on Discord (that I don't even remember) considering I don't think I even share any servers with him. Not to mention Hammerhead went on his Twitter rampage several tens of minutes before he went to my Quora to

Sopi Lote: I’d like to apologize to Infinity Blade for my insults to him on his Twitter and Quora yesterday. I’m sorry about that. I only did it because he called me an idiot on Discord. Then I sent it to a bunch of people who had absolutely nothing to do with it.

Deleted: Supercommunist A while back you asked about fish intelligence. One example that has come to mind is Queensland groupers learning to take fish off of anglers’ lines. Actually, some sharks do the same. I think that learned behavior suggests intelligence.
