Body injuries in male morphotypes of the Amazon River prawn (Macrobrachium amazonicum)

Marine and Freshwater Behaviour and Physiology, 2021
Fights between individuals in a population can be motivated by several factors, such as disputes over food, shelter and sexual partners. The present study aimed to evaluate the pattern of injury occurrence in the Amazon River prawn (Macrobrachium amazonicum).

Histoarchitectural Features of the Hepatopancreas of the Amazon River Prawn Macrobrachium amazonicum [PDF]

International Journal of Morphology, 2009
La glandula digestiva en los crustaceos decapodos asume las funciones de digestion, absorcion de nutrientes, almacenamiento de las reservas energeticas y excrecion de metabolitos. El metabolismo y las alteraciones histologicas e histoquimicas son observados como respuesta a necesidades fisiologicas, tales como: muda, reproduccion y procesos digestivos.

Genetic variability of the Amazon River prawn Macrobrachium amazonicum (Decapoda, Caridea, Palaemonidae) [PDF]

Contributions to Zoology, 2011
The freshwater prawn Macrobrachium amazonicum is widely distributed in South America, and occupies habitats with a wide range of salinities. Several investigations have revealed the existence of wide intraspecific variability among different populations, although the understanding of this variability is still fragmentary and incomplete. We compared and

Social interaction in males of the Amazon river prawn Macrobrachium amazonicum (Heller, 1862) (Decapoda, Palaemonidae)

Crustaceana, 2021
Abstract The large size variation of Macrobrachium amazonicum reflects a complex population structure that consists of four morphotypes, called TC (Translucent Claw), CC (Cinnamon Claw), GC1 (Green Claw 1), and GC2 (Green Claw 2). The effect of the largest morphotype (GC2) claws on development and behaviour of the smallest male morphotype (TC) was ...

Effect of density on population development in the Amazon River prawn Macrobrachium amazonicum [PDF]

Aquatic Biology, 2010
The Amazon River prawn Macrobrachium amazonicum is widely distributed in lentic and lotic environments of South America, and shows different male morphotypes. In the present study, the effect of crowding on the general population structure of this species and its variation over time were evaluated.
