Ali R, Dick M, Muhammad S, Sarver D, Hou L, Wong G, et al.
J Exp Biol
. 2020 Sep;
223(Pt 20).
PMID: 32895327
Hummingbirds, subsisting almost exclusively on nectar sugar, face extreme challenges to blood sugar regulation. The capacity for transmembrane sugar transport is mediated by the activity of facilitative glucose transporters (GLUTs)...

Comp Biochem Physiol A Mol Integr Physiol
. 2019 Aug;
237:110559.
PMID: 31446070
Physiological adaptations that enhance flux through the sugar oxidation cascade permit hummingbirds to rapidly switch between burning lipids when fasted to burning ingested sugars when fed. Hummingbirds may be able...

Sci Rep
. 2018 May;
8(1):8077.
PMID: 29799024
A cardinal feature of the reaction to stress is the promotion of energy mobilization, enabling appropriate behavioural responses. Predator odours are naturalistic and ecologically relevant stressors present over evolutionary timescales....

Workman R, Myrka A, Wong G, Tseng E, Welch Jr K, Timp W
Gigascience
. 2018 Apr;
7(3):1-12.
PMID: 29618047
Background: Hummingbirds oxidize ingested nectar sugars directly to fuel foraging but cannot sustain this fuel use during fasting periods, such as during the night or during long-distance migratory flights. Instead,...

Proc Biol Sci
. 2018 Mar;
285(1873).
PMID: 29491168
Wing kinematics and morphology are influential upon the aerodynamics of flight. However, there is a lack of studies linking these variables to metabolic costs, particularly in the context of morphological...

Welch Jr K, Myrka A, Ali R, Dick M
Physiology (Bethesda)
. 2018 Feb;
33(2):127-137.
PMID: 29412058
Foraging hummingbirds and nectar bats oxidize both glucose and fructose from nectar at exceptionally high rates. Rapid sugar flux is made possible by adaptations to digestive, cardiovascular, and metabolic physiology...

. 2017 Nov;
224:253-261.
PMID: 29127075
Hummingbirds are able to fuel hovering flight entirely with recently ingested glucose or fructose. Among vertebrates, several steps of sugar flux from circulation to skeletal muscle are potentially rate-limiting, including...

Nat Commun
. 2017 Oct;

PMID: 29051535
Flying animals of different masses vary widely in body proportions, but the functional implications of this variation are often unclear. We address this ambiguity by developing an integrative allometric approach,...

PMID: 28018664
Birds undergo numerous changes as they progress through life-history stages, yet relatively few studies have examined how birds adapt to both the dynamic energetic and mechanical demands associated with such...

PMID: 27792729
Inflammation and activation of the acute phase response (APR) are energetically demanding processes that protect against pathogens. Phytohaemagglutinin (PHA) and lipopolysaccharide (LPS) are antigens commonly used to stimulate inflammation and...
