Qnet_Gates {TrenchR}

Net Energy Exchange Between an Animal and the Environment

Description

The function estimates the net energy exchange (W) between an animal and the environment. The function follows Gates (1980) and others.

Usage

Qnet_Gates(Qabs, Qemit, Qconv, Qcond, Qmet, Qevap)

Arguments

Qabs

numeric solar radiation absorbed (W).

Qemit

numeric thermal radiation emitted (W).

Qconv

numeric energy exchange due to convection; Energy exchange from an animal to its surrounding environment (air or water) (W).

Qcond

numeric energy exchange due to conduction; Energy exchange from animal to a surface if they are in contact (W).

Qmet

numeric energy emitted due to metabolism (W).

Qevap

numeric energy emitted due to evaporative water loss (W).

Value

numeric net energy exchange (W).
