Early Post-Release Movement Convergence in Reintroduced Giant Pandas. [PDF]

open access: yesEcol Evol
We used high‐frequency GPS tracking of eight reintroduced giant pandas (474 tracking days) to test how extreme energetic constraints shape movement during early post‐release adjustment. Principal component analysis of ten daily movement metrics revealed two independent movement axes (exploration–exploitation and tortuosity–consistency), and an ...

Influence of Solvent Lipid Extraction on Tissue‐Specific Carbon Isotopes [PDF]

open access: yesEcol Evol
To assess the impact of solvents on δ13C, we used a standard lipid extraction protocol on four different pure proteins and humpback whale blubber, a very lipid‐rich tissue. The results showed that the solvents did not have a significant effect on δ13C and δ15N of pure proteins as values largely remained within 0.5‰ of unextracted samples, which is ...
