Hypoxia and interdemic variation in Poecilia latipinna
Variation in respiratory traits was quantified between two populations of the sailfin molly Poecilia latipinna (one from a periodically hypoxic salt marsh, Cedar Key, and one from a chronically normoxic river site, Santa Fe River). Two suites of characters were selected: traits that may show both short-term acclimation response and interdemic variation in acclimation response (metabolic rate, c...
متن کاملFemale sperm limitation in natural populations of a sexual/asexual mating complex (Poecilia latipinna, Poecilia formosa).
In sperm-dependent sexual/asexual mating systems, male mate choice is critical for understanding the mechanisms behind apparent stability observed in natural populations. The gynogenetic Amazon molly (Poecilia formosa) requires sperm from sexual males (e.g. Poecilia latipinna) to trigger embryogenesis, but inheritance is strictly maternal. Consequently, males should try to avoid or reduce the c...
متن کاملStudy on induced breeding in ornamental fish,poecilia sphenops
An attempt has been made to determine the effect of Natrum muriaticum, a homeopathic medicine on the weight gain, fecundity, excretion and tissue protein level in Poecilia sphenops (white molly), an ornamental viviparous fish. Natrum muriaticum of 30 centesimal potency of dilution of 0.025% medium was used. The amount of protein was determined in the ovary, liver and muscle of the control and t...
متن کاملPopulation Genomics of the Euryhaline Teleost Poecilia latipinna
Global climate change and increases in sea levels will affect coastal marine communities. The conservation of these ecologically important areas will be a challenge because of their wide geographic distribution, ecological diversity and species richness. To address this problem, we need to better understand how the genetic variation of the species in these communities is distributed within loca...
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...
