Perchlorate Exposure Reduces Primordial Germ Cell Number in Female Threespine Stickleback
Perchlorate is a common aquatic contaminant that has long been known to affect thyroid function in vertebrates, including humans. More recently perchlorate has been shown to affect primordial sexual differentiation in the aquatic model fishes zebrafish and threespine stickleback, but the mechanism has been unclear. Stickleback exposed to perchlorate from fertilization have increased androgen le...
متن کاملCorrelates of prolonged swimming performance in F2 hybrids of migratory and non-migratory threespine stickleback.
Determining which underlying traits contribute to differences in whole-animal performance can be difficult when many traits differ between individuals with high and low capacities. We have previously found that migratory (anadromous marine) and non-migratory (stream-resident) threespine stickleback (Gasterosteus aculeatus) populations have genetically based differences in prolonged swimming per...
متن کاملEffects of fin size on swimming performance, swimming behaviour and routine activity of zebrafish Danio rerio.
The zebrafish Danio rerio exhibits substantial morphological variability in the sizes and shapes of the body and the caudal fin. The present study describes swimming performance, swimming behaviour and routine locomotor activity patterns in three of the major morphotypes: wild-type, long-finned and no-tail. Wild-type and long-finned differ in total length (TL), fork length (FL), caudal fin leng...
متن کاملPrenatal Caffeine Exposure Impairs Pregnancy in Rats
Background In recent years, concerns have been raised about human reproductive disorders. Caffeine consumption is increasing by the world’s population and there is a relationship between caffeine intake and adverse reproductive outcomes. The aim of this study was to evaluate the effects of caffeine on implantation sites, number of live births, birth weight, crown-rump length (CRL) and abnormali...
متن کاملFoeniculum vulgare (Fennel) Effects on Puberty Timing, Reproductive Function and Behaviour in Adult Female Mice Following Neonatal Exposure
Background & Objective: Fennel, as an edible plant, and due to its estrogenic compounds, has widely been used as a therapeutic agent for centuries. In this study, the effects of neonatal exposure to fennel alcoholic extract (FAE), on the onset of puberty, estrus cycle, ovaries, and lordosis were investigated. Materials & Methods: In this experimental study, 48 female BALB/c pups were divid...
