Life History Traits of Shrimps (Decapoda: Palaemonidae) of Amazonian Inland Waters and their Phylogenetic Interpretation
Amazonian shrimps (Decapoda, Palaemonidae) of several genera from the generally nutrient-poor, acid waters of the Rio Negro basin show two different breeding patterns: in the annually inundated (Jan./Feb. to Sept./Oct.) lowland forest (= ”igapo”) they breed during a period with rising and high water...
