Avian BMR in Marine and Non-Marine Habitats: A Test Using Shorebirds
Marine
Non-marine
BMR
Basal Metabolic Rate
MR BThe minimum rate of energy
expenditure of normothermic homeotherms under thermoneutral and post-absorptive conditions in the inactive phase of the circadian cycle
Migratory shorebird(Charadriiformes 鴴目 )
Divided into broad categories (coastal & inland) in terms of their habitat occupancy outside the breeding season.
Interspecific analysis→Variation in BMR attributed to genotypic divergence.
Intraspecific analysis→ Inland habitats < Marine habitats (15%)→ Phenotypic plasticity
Results
Discussion
• Tidally-induced food restrictions• High salinity• Windy microclimates associated with
coastal saline habitats
BMR↑ (For Marine species)
Eliminate phenotypic plasticity as a source of phenotypic variation.
