Lema S, Luckenbach J, Yamamoto Y, Housh M
Philos Trans R Soc Lond B Biol Sci . 2024 Feb; 379(1898):20220516. PMID: 38310938
Reproduction in fishes is sensitive to temperature. Elevated temperatures and anomalous 'heat waves' associated with climate change have the potential to impact fish reproductive performance and, in some cases, even...

Bersin T, Cordova K, Journey M, Beckman B, Lema S
Gen Comp Endocrinol . 2023 Nov; 346:114404. PMID: 37940008
Growth hormone (Gh) regulates growth in part by stimulating the liver to synthesize and release insulin-like growth factor-1 (Igf1), which then promotes somatic growth. However, for fish experiencing food limitation,...

Bersin T, Mapes H, Journey M, Beckman B, Lema S
Comp Biochem Physiol A Mol Integr Physiol . 2023 May; 282:111444. PMID: 37201654
Fish adjust rates of somatic growth in the face of changing food consumption. As in other vertebrates, growth in fish is regulated by the growth hormone (Gh)/insulin-like growth factor-1 (Igf1)...

Bersin T, Cordova K, Saenger E, Journey M, Beckman B, Lema S
Mol Cell Endocrinol . 2023 May; 573:111951. PMID: 37169322
Insulin-like growth factor-1 (Igf1) regulates skeletal muscle growth in fishes by increasing protein synthesis and promoting muscle hypertrophy. When fish experience periods of insufficient food intake, they undergo slower muscle...

Shew J, Lema S
Mitochondrial DNA B Resour . 2023 Jan; 8(1):13-17. PMID: 36620321
The jack silverside (), also referred to as jacksmelt, is a neotropical silverside fish that inhabits nearshore shallow waters of the California Current Ecosystem in the Northeast Pacific Ocean, ranging...

Lema S, Chow M, Dittman A, May D, Housh M
Comp Biochem Physiol A Mol Integr Physiol . 2022 Jul; 272:111280. PMID: 35902003
Many fish experience diminished reproductive performance under atypically high or prolonged elevations of temperature. Such high temperature inhibition of reproduction comes about in part from altered stimulation of gametogenesis by...

Breves J, McKay I, Koltenyuk V, Nelson N, Lema S, McCormick S
J Comp Physiol B . 2022 Jun; 192(5):577-592. PMID: 35715660
The life history of Atlantic salmon (Salmo salar) includes an initial freshwater phase (parr) that precedes a springtime migration to marine environments as smolts. The development of osmoregulatory systems that...

Bock S, Chow M, Forsgren K, Lema S
Mol Cell Endocrinol . 2021 Sep; 537:111447. PMID: 34469772
Fish experiencing abnormally high or prolonged elevations in temperature can exhibit impaired reproduction, even for species adapted to warm water environments. Such high temperature inhibition of reproduction has been linked...

Del Core A, Cleveland C, Lema S
Mitochondrial DNA B Resour . 2021 Jul; 6(8):2229-2232. PMID: 34263054
The Salt Creek pupfish, Miller, 1943 is endemic to Death Valley, California, USA, and resides as a single population within one of the most extreme inland aquatic environments capable of...

Glaser F, Owen K, Henkanaththegedara S, Parmenter S, Stockwell C, Lema S
Mitochondrial DNA B Resour . 2021 Jan; 2(2):797-799. PMID: 33473985
The Mohave tui chub () is an endangered cyprinid fish endemic to the Mojave Desert region of southeastern California, USA. Here, we describe the complete 16,607 base pair (bp) mitochondrial...
