Cnidae sizes in the two morphotypes of the giant Caribbean anemone Condylactis gigantea (Actiniaria: Actiniidae)
(Universidad de Costa Rica, 2018)
Morphotypes in male Amazon River Prawns, Macrobrachium amazonicum
(2004-06-14)
The occurrence of morphotypes in Macrobrachium amazonicum males was investigated. Prawns aged 4 to 24 months were taken from 10 aquaculture earthen ponds. Color and spination of right second cheliped were analyzed under a ...

The androgenic gland in male morphotypes of the Amazon River prawn Macrobrachium amazonicum (Heller, 1862)
(2019-05-01)
Sexual differentiation and primary and secondary sexual characteristics in male crustaceans are modulated by hormones produced in the androgenic gland (AG). The AG is also responsible for the determination of morphotypes ...
Glandular trichome diversity on leaves of Lippia origanoides and Lippia stachyoides (Verbenaceae): morphology, histochemistry, and ultrastructure
(Canadian Science Publishing, Nrc Research Press, 2015-05-01)
Despite the ecological and medicinal importance of glandular trichomes in Verbenaceae, information on their structure, mainly at the subcellular level, is sparse. We analyzed the morphology and histochemistry of glandular ...
Male morphotypes of the freshwater prawn Macrobrachium brasiliense (Decapoda: Caridea: Palaemonidae)
(2020-03-01)
Some decapod species have intraspecific morphological variations that result in distinct adult morphotypes that influence the population structure, social dominance, and reproduction of the population. Here we investigated ...
Candida albicans morphotypes from oral cavity in several families
(Universidad de Valparaíso, 1998)
Are there any physiological differences between the male morphotypes of the freshwater shrimp Macrobrachium amazonicum (Heller, 1862) (Caridea: Palaemonidae)?
(2016-01-01)
A comparison was made of the metabolism, nitrogenous excretion, growth, oxidized energy substrate, ingestion rate, and fecal production of the males of three morphotypes (CC, GC1, and GC2) of the palaemonid shrimp Macrobrachium ...
Male morphotypes in the andean river shrimp cryphiops caementarius (decapoda: caridea): morphology, coloration and injuries
(WILEY-BLACKWELL, 2012)
In many species, different male morphotypes usually employ different tactics to access resources. Males with highly developed weapons are expected to fight and possibly incur higher levels of injury than males with less ...
