Komar E, Szafranska P, Dechmann D, Keicher L, Koprowska D, Shipley J, et al.
J Exp Biol
. 2025 Feb;
PMID: 39973358
1. Energy can be limiting, especially for small animals with high metabolisms, particularly if they rely on ephemeral resources. Some energy-saving strategies, such as torpor, can impair physiological processes. Alternatively,...

Proc Biol Sci
. 2024 Jul;
291(2026):20240855.
PMID: 38981523
Understanding how animals meet their daily energy requirements is critical in our rapidly changing world. Small organisms with high metabolic rates can conserve stored energy when food availability is low...

Dietzer M, Keicher L, Kohles J, Hurme E, Ruczynski I, Borowik T, et al.
Sci Rep
. 2024 Mar;
14(1):7498.
PMID: 38553552
Increasing agriculture and pesticide use have led to declines in insect populations and biodiversity worldwide. In addition to insect diversity, it is also important to consider insect abundance, due to...

Shankar A, Welch K, Eberts E, Geiser F, Halter S, Keicher L, et al.
Integr Comp Biol
. 2023 Jul;
PMID: 37419503
Torpor is an incredibly efficient energy-saving strategy that many endothermic birds and mammals use to save energy, by lowering their metabolic rates, heart rates, and typically body temperatures. Over the...

Pohle A, Zalewski A, Muturi M, Dullin C, Farkova L, Keicher L, et al.
R Soc Open Sci
. 2023 Jul;
10(7):230463.
PMID: 37416828
A typical consequence of breeding animal species for domestication is a reduction in relative brain size. When domesticated animals escape from captivity and establish feral populations, the larger brain of...

Keicher L, Shipley J, Schaeffer P, Dechmann D
Integr Comp Biol
. 2023 May;
63(5):1087-1098.
PMID: 37237444
Metabolic processes of animals are often studied in controlled laboratory settings. However, these laboratory settings often do not reflect the animals' natural environment. Thus, results of metabolic measurements from laboratory...

Keicher L, Shipley J, Komar E, Ruczynski I, Schaeffer P, Dechmann D
J Comp Physiol B
. 2022 Aug;
192(6):805-814.
PMID: 35939092
Torpor is characterized by an extreme reduction in metabolism and a common energy-saving strategy of heterothermic animals. Torpor is often associated with cold temperatures, but in the last decades, more...

Schaeffer P, OMara M, Breiholz J, Keicher L, Lazaro J, Muturi M, et al.
R Soc Open Sci
. 2020 May;
7(4):191989.
PMID: 32431881
Small endothermic mammals have high metabolisms, particularly at cold temperatures. In the light of this, some species have evolved a seemingly illogical strategy: they reduce the size of the brain...

Hulsey C, Machado-Schiaffino G, Keicher L, Ellis-Soto D, Henning F, Meyer A
G3 (Bethesda)
. 2017 Jul;
7(9):3195-3202.
PMID: 28751505
The independent evolution of the two toothed jaws of cichlid fishes is thought to have promoted their unparalleled ecological divergence and species richness. However, dental divergence in cichlids could exhibit...

J Exp Biol
. 2017 May;
220(Pt 15):2834-2841.
PMID: 28546508
Small non-migratory mammals with Northern distribution ranges apply a variety of behavioural and physiological wintering strategies. A rare energy-saving strategy is Dehnel's phenomenon, involving a reduction and later regrowth of...
