The oxygen consumption of adult fish (Q) is proportional to their body weight (W) raised a power, estimated as the slope (dQ) linear regression log(Q) vs. log(W). Similarly, gill surface area (GSA) W power dG, also via log-log area. Moreover, because Fick’s laws diffusion, dQ should be at least similar dG. Recently, claim has been made that non-zero differences between and dG invalidate Gill-Oxygen Limitation Theory (GOLT), which suggests O2 supplied by gills growing with <1 limits growth older larger fish. We show here, based on 33 pairs in species other information (i) while individual are observed several cases, there no significant overall difference across estimates (ii) large primarily due ontogenetic changes scaling (OCS), likely gills’ water–blood (or ‘diffusion’) distance and, well, multiple sources experimental variability potential errors, leading outliers random differences.

Abstract In obesity research, the importance of core body temperature ( CBT ) regulation is often neglected. thermogenic regulation, however, plays a crucial role in heat management through convection, radiation, and conduction processes to remove from body, as well metabolic that sequester lipogenesis. This review emphasizes even small changes can significantly impact events ranging ATP production fat deposition. Accordingly, case made physical events, such external exposure, also compositional changes, do work processes. Examples are provided suggest independent diet exercise, where one lives, have an on composition obesity. For example, below 35 degrees earth's latitude, rates 40 percent or greater among adults. However, regions between 45 50 US ‐Canadian border, 25%–30%.
