Description


Here's my side-blotched lizard in the sagebrush habitat I'm currently finishing up. The plants in the background are Ericameria nauseosa (aka Gray Rabbitbrush). I also modeled a Great Basin Sagebrush (Artemisia tridentata) and Blue Grama grass (Bouteloua gracilis) for the set which aren't shown in this render. The side-blotched lizard is found on Pacific Coast of North America. It is notable for having a unique form of polymorphism wherein each of the three different male morphs utilizes a different strategy in acquiring mates. The three morphs compete against each other following a pattern of rock, paper, scissors, where one morph has advantages over another but is out-competed by the third. > Orange-throated males are “ultradominant”. They are the largest and most aggressive morph, defending relatively large (about 100 m2 or 120 yd2) territories and keeping harems of females with which they mate. They are adept at stealing mates from blue-throated individuals, but are vulnerable to cuckoldry by the yellow-throated female mimics. Orange-throated males also have significantly reduced yearly survival rates compared to the other two morphs. > Blue-throated males are "dominant". They are intermediate in size, and guard smaller territories containing only a single female. As they only have one mate to defend, they are better at catching yellow-throated sneaks, but are also susceptible to having their mates stolen by the larger, more aggressive orange-throated males. > Yellow-throated males are “sneakers”. Their coloration is similar to that of sexually mature females, and they typically mimic female “rejection” displays when they encounter dominant orange- or blue-throated males. Unlike the other morphs, yellow-throated males do not hold territories. Instead, they have wide-reaching home ranges that may overlap with several other lizards’ territories.They rely on their mimicry to sneak matings with unattended females. This is more easily achieved among the harems kept by orange-throated males than by the single, closely guarded mate of the blue-throated males. Though orange-throated males have the highest mortality rates, yellow-throated males have higher relative rates of posthumous fertilization (posthumous birth), indicating an increased reliance on sperm competition as part of their reproductive strategy.Yellow-throated males can in specific instances transform into blue-throated males over the course of the breeding season. This transformation is usually triggered by the death of a nearby dominant male, and the blue patches the yellow-throated males develop is qualitatively distinct from the blue patches of genetically blue-throated males. Not all yellow-throated males transform, but when they do, they give up their female mimicry and adopt the “dominant” morph's behavior pattern. No transformations in the other direction, in which dominant males gain yellow-throat coloration, have been observed. Rendered in DAZ Studio IRay with no postwork.
