Hi Dennis,
I actually work in the graduate career center at my university (my fellowship is doing that rather than teaching) and this is what we specialize in! I too am a PhD student moving out of academia after the PhD. Many of our office's online resources are applicable to any PhD... (read more)

Hello Rob,
I have seen the bracelet style used on large mammals with mixed success and failure. The main considerations are terrain the animal uses, and fitting the bracelet properly. Both affect the 1. durability of the tag and 2. whether it cuts into the skin. In the case of fitting to... (read more)

Thanks Thomas. The option of desertstar seems strong, and it needs to be strong for the animals I work with (large carnivores). Indeed the pod would need to be designed to fit the collar type, but that's not impossible. (read more)
Hey Rob,
the runtime depends very much on sampling rates and data types that are collected. In Table 1 in the paper we explored runtimes for 12mAh and 25mAh batteries. If the homerange of an animal can be covered entirely by the tracking grid (in our case 1.5ha) and you track the animal... (read more)

Hi Isla,
Range at which animals hear sounds depend on 4 things:
