Padmanaban N, Ambosie R, Choy S, Marcus S, Nilsson S, Keene A, et al.
bioRxiv
. 2025 Feb;
PMID: 39975198
Behavioral stress responses allow animals to quickly adapt to local environments and are critical for survival. Stress responses provide an ideal model for investigating the evolution of complex behaviors due...

Roback E, Ferrufino E, Moran R, Shennard D, Mulliniks C, Gallop J, et al.
Mol Biol Evol
. 2025 Jan;
42(2).
PMID: 39833658
Loss-of-function alleles are a pertinent source of genetic variation with the potential to contribute to adaptation. Cave-adapted organisms exhibit striking loss of ancestral traits such as eyes and pigment, suggesting...

Culver D, Kowalko J, Pipan T
Front Ecol Evol
. 2024 Nov;
11.
PMID: 39606270
Throughout the evolutionary tree, there are gains and losses of morphological features, physiological processes, and behavioral patterns. Losses are perhaps nowhere so prominent as for subterranean organisms, which typically show...

Gallman K, Rastogi A, North O, OGorman M, Hutton P, Lloyd E, et al.
J Exp Zool A Ecol Integr Physiol
. 2024 Nov;
341(10):1084-1096.
PMID: 39539086
Interactions between sleep and feeding behaviors are critical for adaptive fitness. Diverse species suppress sleep when food is scarce to increase the time spent foraging. Postprandial sleep, an increase in...

Wiese J, Richards E, Kowalko J, McGaugh S
J Hered
. 2024 Jul;
116(2):89-100.
PMID: 39079020
A major goal of modern biology is connecting phenotype with its underlying genetic basis. The Mexican cavefish (Astyanax mexicanus), a characin fish species comprised of a surface ecotype and a...

bioRxiv
. 2024 Jul;
PMID: 38948816
Understanding the phenotypic consequences of naturally occurring genetic changes, as well as their impact on fitness, is fundamental to understanding how organisms adapt to an environment. This is critical when...

Zebrafish
. 2024 Feb;
21(3):255-258.
PMID: 38354295
is an emerging model system used to study development, evolution, and behavior of multiple cavefish populations that have repeatedly evolved from conspecific surface fish. Although surface and cavefish live and...

Curr Biol
. 2023 Sep;
33(18):R953-R955.
PMID: 37751707
While many species are active during specific time periods throughout the day, there is significant variation across species in preferred daily temporal niche. A new study investigates the molecular changes...
