...Naim M. Bautista; Hans Malte; Chandrasekhar Natarajan; Tobias Wang; Jay F. Storz; Angela Fago ABSTRACT Crocodilians are unique among vertebrates in that their hemoglobin (Hb) O 2 binding is allosterically regulated by bicarbonate, which forms in red blood cells upon hydration of CO 2 . Although...

.... In contrast, in the bats switched to the amaranth diet, carbon half-life(39.7±3.4 days) was longer than that of nitrogen (25.0±6.0 days). The enrichment in 15 N between diet and blood was higher when bats were fed the amaranth diet (4.4±0.2‰) than when they were fed the soya diet (3.3±0.2‰). Similarly, bats...
