Genetic Composition of Laboratory Stocks of the Self-Fertilizing Fish Kryptolebias marmoratus: A Valuable Resource for Experimental Research
TLDR
A genetic inventory of essentially all laboratory stocks of the Mangrove Killifish held worldwide shows extensive interline differentiation as well as some intraline variation, much of which can be attributed to post-origin de novo mutations and/or to the segregation of polymorphisms from wild progenitors. Expand
Extensive outcrossing and androdioecy in a vertebrate species that otherwise reproduces as a self-fertilizing hermaphrodite.
TLDR
It is found that outcrossing (probably between gonochoristic males and hermaphrodites) is common at the Belize site, and the dramatic impact that functional androdioecy can have on the population genetic architecture of this reproductively unique vertebrate species is demonstrated. Expand
Microsatellite documentation of male-mediated outcrossing between inbred laboratory strains of the self-fertilizing mangrove killifish (Kryptolebias Marmoratus).
TLDR
These laboratory findings experimentally confirm that conspecific males can mediate occasional outcross events and that this process can release extensive genic heterozygosity. Expand
A mixed-mating strategy in a hermaphroditic vertebrate
TLDR
A remarkable instance of evolutionary convergence to an analogous mixed mating system by a vertebrate, the mangrove killifish (Kryptolebias marmoratus), is documented, resulting in a local population genetic pattern that differs qualitatively from the genetic architectures known in any other vertebrate species.

GENETIC AND MORPHOLOGICAL IDENTIFICATION OF FUCUS RADICANS SP. NOV. (FUCALES, PHAEOPHYCEAE) IN THE BRACKISH BALTIC SEA 1
TLDR
It is reported here that a population of this unique morphotype is reproductively isolated from a truly sympatric population of common F. vesiculosus and concluded that the northern morphotype represents a previously undescribed species. Expand
Effects of Pleistocene climatic fluctuations on the phylogeographic and demographic histories of Pacific herring (Clupea pallasii)
TLDR
The genetic make‐up of extant populations of C. pallasii was shaped by Pleistocene environmental impacts on the historical demography of this species, resulting in a deep genealogical split that cleanly distinguishes populations in the western vs. eastern North Pacific. Expand
On the Evolution of Dopa decarboxylase (Ddc) and Drosophila Systematics
TLDR
Most of the coding region of the gene Dopa decarboxylase (Ddc) in 24 fruitfly species is sequenced, which favors the hypothesis that Chymomyza is older than Scaptodrosophila, although this issue is not definitely resolved. Expand
Multiple mating and clutch size in invertebrate brooders versus pregnant vertebrates
TLDR
In embryo-gestating animals otherwise as different as mammals and mollusks, polygamy rates and histograms of successful mates per brooder proved to be strikingly similar, and no significant correlation in invertebrates between brood size and genetically deduced rates of multiple mating by the incubating sex was uncovered. Expand
Pronounced reproductive skew in a natural population of green swordtails, Xiphophorus helleri
TLDR
This study exhaustively analyzed a population of green swordtail fish for genetic paternity (and maternity) using a suite of highly polymorphic microsatellite loci and showed that the opportunity for selection on male X. helleri is among the highest yet reported in fishes, and it is intermediate compared to estimates available for mammals.
