Although mangrove rivulus populations tend to have very high rates of selfing, there is population genetic evidence for outcrossing and associated heterozygosity, even in populations where males have not been identified (Mackiewicz et al., 2006b; Tatarenkov et al., 2012).

Es de relevancia recalcar que de los paratipos de Rivulus bondi (MBUCV V- 7001) colectados en el rio Guaire, el 40 % presento el cromotipo intermedio con una talla menor a 35 mm.

cDNA cloning and expression of a cytochrome P450 1A (CYP1A) gene from the hermaphroditic fish Rivulus marmoratus.

10:30 LOG PACKING BEHAVIORS IN THE MANGROVE RIVULUS. KRYPTOLEBIAS MARMORATUS, D.L.

Such was the case when biology professor Alice Gibb and her research team at Northern Arizona University witnessed a small amphibious fish, the mangrove rivulus, jump with apparent skill and purpose out of a small net and back into the water.

Endocrine disrupting chemicals (bisphenol A, 4-nonylphenol, 4-ferf-octylphenol) modulate expression of two distinct cytochrome P450 aromatase genes differently in gender types of the hermaphroditic fish Rivulus marmoratus.

The little cryptic mangrove rivulus (killifish) lives in giant land crab burrows.

Metacercariae were located in muscular tissues, under the scale of the caudal fin of Rivulus harti (natural infection).

Relationships among species of Rivulus endemic to the Brazilian Amazonas river basin are evaluated through an analysis of morphological characters, including terminal taxa representative of all Rivulus lineages.

Equally at home on land and in the water, the mangrove rivulus is a secretive, oddball fish that often hides in crab burrows and generally produces clones of itself.
