| dc.description | Understanding the interspecific morphological variability of Caquetaia kraussii (Perciformes: Cichlidae) between different localities in its distribution range is becoming essential, as
this species constitutes a valuable resource for the economy and subsistence of the local human
communities where it is endemic in Colombia and Venezuela. In order to develop efficient farming
and handling plans for this species, a deep understanding of the factors and mechanisms generating
morphological variability is crucial. This study analyzes the morphological variability of C. kraussii by
using geometric morphometrics in four localities distributed between the Dique and North channels,
which are part of the Bolívar department in Colombia. Likewise, the effect of environmental variables
such as temperature (T◦
), dissolved oxygen (OD) and pH on morphological variability was analyzed
using a partial least squares approach. The results show that environmental stress has an influence on
~10% of the body shape of C. kraussii, whereas ~90% of the body shape is not directly influenced by environmental parameters, suggesting an effect from stress related to sexual dimorphism. Similarly, the
analyses show shape variation among localities, mainly between populations of lotic environments
and those of lentic environments. This morphological disparity seems to be subject to environmental
and sexual stresses in the different localities. | |
