Power analysis of wolf-moose functional responses
Article Abstract:
The modified Michaelis-Menton equation has been used as the functional response model to assess the power of distinguishing between shapes of functional response curves for wolf-moose systems. This research was based on the premise that the ability to distinguish among potential functional response models is restricted by the ability to gather sufficient sample sizes for systems with considerable variability. The power analysis indicated that there was low power to distinguish between a Type II and a Type III functional response through nonlinear least-squares regression.

Towards a functional explanation for the occurrence of anorexia during parasitic infections
Article Abstract:
The functional basis of the occurrence of anorexia during parasitic infections among animals was proposed. Several hypothesis were then suggested to explain the occurrence of anorexia. One is that the anorexia caused by parasites is beneficial to the host by promoting immune response and that intake is reduced to cause starvation among parasites. Anorexia also decreases energetic efficiency, which gives rise to minimized intake and promotes diet selectivity.

Oxygen consumption during crowing by roosters: talk is cheap
Article Abstract:
There is a direct relationship between oxygen consumption and crowing in roosters. However, this consumption was significantly less than the amount of oxygen that is consumed by the roosters while indulging in other activities. Oxygen consumption by insects and frogs while calling is much higher than it is in roosters. A closed-circuit calorimeter was used to measure oxygen consumption.
