Journal ArticleDOI
Natural hybridization between divergent lineages in a selfing hermaphroditic fish.
TL;DR: The results show that although mangrove rivulus fish are mostly highly selfing in nature (resulting in isogenic, effectively clonal and homozygous progeny), classification within this taxonomic complex need not be incompatible with the BSC.
Journal ArticleDOI
How individual and relative size affect participation in territorial defense and cortisol levels in a social fish.
TL;DR: Defense against conspecific and heterospecific territorial intruders by members of successfully breeding pairs in the cichlid fish Neolamprologus pulcher is investigated, and whether cortisol levels were associated with size or participation in territory defense is investigated.
Journal ArticleDOI
Ready for a fight? The physiological effects of detecting an opponent's pheromone cues prior to a contest.
TL;DR: It was found that exposure to a competitor's pheromone cues elicited a significant increase in testosterone levels, and testosterone levels were similar across genetically distinct lineages derived from geographically distinct populations.
Journal ArticleDOI
Changes in reproductive physiology of mangrove rivulus Kryptolebias marmoratus following exposure to environmentally relevant doses of ethinyl oestradiol.
TL;DR: Exposure to EE2 resulted in a decrease in spermatid and sperMatocyte density in males and an increase in the number of early stage oocytes in hermaphrodites, whereas only males exhibited a significant decrease in KT.
Journal ArticleDOI
Phenotypically plastic responses to predation threat in the mangrove rivulus fish (Kryptolebias marmoratus): behavior and morphology
TL;DR: The results suggest that rivulus exhibit phenotypic plasticity in response to cues associated with predator threat and that historical effects from selection or other evolutionary processes also are important determinants of behavioral and morphological variation.
