Cave amphipods reveal co-variation between morphology and trophic niche in a low-productivity environment
<p>Datasets used to explore co-variation patterns between morphological traits and trophic niche in co-occurring <em>Niphargus</em> amphipods from five groundwater caves of the Dinaric Karst, Europe. We quantified gnathopod size and shape by means of morphometric measurements and assessed isotopic niche, trophic position, and carbon signatures using nitrogen (δ<sup>15</sup>N) and carbon (δ<sup>13</sup>C) stable isotopes. We provide morphometric and isotopic data for <em>Niphargus</em> specimens, and isotopic data for food resources sampled in the caves.</p>

Genetic variation of morphological scaling in Drosophila
<p>Morphological scaling relationships between the sizes of individual traits and the body captures the characteristic shape of a species, and the evolution of scaling is the primary mechanism of morphological diversification. However, we have almost no knowledge of the genetic variation of scaling, which is critical if we are to understand how scaling evolves. Here we explore the genetics of population morphological scaling relationships – the scaling relationship fit to multiple genetically-distinct individuals in a population – by describing the distribution of individual scaling relationships – the genotype-specific scaling relationships that are unseen or cryptic. These individual scaling relationships harbor the genetic variation that determines relative trait growth within individuals, and theoretical studies suggest that their distribution dictates how the population scaling relationship will respond to selection. Using variation in nutrition to generate size variation within 194 isogenic lineages of <em>Drosophila</em> <em>melanogaster</em>, we reveal extensive variation in the slopes of the wing-body and leg-body scaling relationships among genotypes. This genetic variation reflects variation in the nutritionally-induced size plasticity of the wing, leg, and body. Surprisingly, we find that variation in the slope of individual scaling relationships primarily results from variation in nutritionally-induced plasticity of body size, not leg or wing size. These data allow us to predict how different selection regimes affect scaling in <em>Drosophila</em> and are the first step in identifying the genetic targets of such selection. More generally, our approach provides a framework for understanding the genetic variation of scaling, an important prerequisite to explaining how selection changes scaling and morphology.</p>
