Mating systems and sexual selection in male-pregnant pipefishes and seahorses: Insights from microsatellite-based studies of maternity

Article Abstract:

Mating and sexual behaviour among Syngnathidae (pipefishes and seahorses) is examined, focusing on data produced via microsatellite-based studies, including the occurrence of genetic monogamy, polygynandry, and polyandry among the species.

Male pregnancy in seahorses and pipefishes (family Syngnathidae): Rapid diversification of paternal brood pouch morphology inferred from a molecular phylogeny

Article Abstract:

Male pregnancy among Syngnathidae species (pipefishes and seahorses) is examined, focusing on the morphological structures featured on the species. Interoceanic migration of pipefishes has also been identified.

The molecular basis of a microsatellite nulle allele from the White Sands pupfish

Article Abstract:

Microsatellite loci from the White Sands pupfish (Cyprinodon tularosa) were cloned and characterized. One locus had a high-frequency non-amplifying allele localized to a single population. This null allele was PCR amplified by redesign of one of the original primers and multiple individuals homozygous for null and for nonnull alleles were sequenced utilizing the new primer. Molecular dissections indicated that a previous failure to amplify some alleles from this microsatellite locus was caused by a 4 bp deletion in one of the original PCR priming sites.
