Reproductive Biology of Sailfin Molly, Poecilia latipinna (Lesueur, 1821) in Wadi Haneefah Stream, Riyadh, Saudi Arabia
The reproductive biology of Poecilia latipinna inhabiting Wadi Haneefah stream, Riyadh, Saudi Arabia was studied. The fish (P. latipinna) were found reproductively active round the year. The highest reproductive activity occurred from February to May and August to November which defined two distinct annual periods of reproduction. There was a monthly variation in sex ratio. More females than ma...
متن کاملFeeding rates in the sailfin molly Poecilia latipinna and its coexisting sexual parasite, the gynogenetic Amazon molly Poecilia formosa.
Feeding rates of the gynogenetic Amazon molly Poecilia formosa and one of its sexual hosts, the sailfin molly Poecilia latipinna, were measured under winter and summer temperature conditions. Food consumption of the unisexual P. formosa in winter conditions was significantly higher than that of P. latipinna, and it is hypothesized that the resulting food stress might have an important influence...
متن کاملMate choice copying in the sailfin molly, Poecilia latipinna, in the wild
Mate choice copying has been documented extensively in the laboratory with almost no supporting data available from studies in the wild. We investigated male and female mate choice copying in a wild population of the sailfin molly, a species that shows copying in the laboratory. We set up two upside-down plastic tanks in a river, with two jars of water on each tank. In male mate choice trials w...
متن کاملBehavioral and physiological compensation for chronic hypoxia in the sailfin molly (Poecilia latipinna).
This study demonstrates that short-term behavioral and physiological responses may permit the sailfin molly Poecilia latipinna to cope successfully with extreme hypoxia and suggests an interaction between behavioral response (aquatic surface respiration [ASR]) and physiological compensation. Poecilia latipinna acclimated to chronic hypoxia (6 wk at 1.0 mg L(-1) O(2)) exhibited higher hemoglobin...
متن کاملMultiple paternity in different populations of the sailfin molly, Poecilia latipinna
Rates of multiple paternities were investigated in the sailfin molly (Poecilia latipinna), using eight microsatellite loci. Genotyping was performed for offspring and mothers in 40 broods from four allopatric populations from the south-eastern U.S.A. along a geographic stretch of 1200 km in west-east direction and approximately 200 km from north to south. No significant differences regarding ra...
