Paleoecological evidence for environmental specialization in
Paranthropus boisei compared to early Homo

Yes, no doubt boisei fed mostly on AHV (aquatic herbaceous vegetation): >"Paleo-environmental, dento-gnathic, micro-wear and isotopic data independently
suggest that East-African australopiths, not unlike extant lowland gorillas in forest bais,
might frequently have fed partly or largely on papyrus sedges in the swamps where
their fossils lay (Puech et al. 1986, Conroy 1990, Puech 1992, van der Merwe et al. 2008,
Stewart 2010, Sponheimer et al. 2013)."

The high C4 isotopic signal in their teeth suggest they may have been graminivorous (most aquatic vegetation is C3), but their low-crowned bunodont molars suggest they were not (the typical graminivore has
hypsodont dentition, high-crowned and sharply crested).
Their consistent association with other C4-feeders such as the grazing
pig Metridiochoerus (giant warthog) and Theropithecus suggest grassy environments.
And why did P.boisei disappear from the fossil record after ~1.3 Ma? https://www.nature.com/articles/s41598-021-86642-z
