Effect of the aspen leaf miner feeding damage on aspen leaf gas exchange and water relations from south-facing site on the University of Alaska Fairbanks campus: Fairbanks, Alaska 2018
This dataset addresses the effects of epidermal leaf mining by the aspen leaf miner (Phyllocnistis populiella) on the physiology and water relations of aspen leaves. The dataset contains measurements of gas exchange, water potential, water content, and delta13C of aspen leaves manipulated to bear leaf mining damage on the top (adaxial) leaf surface only, the bottom (abaxial) leaf surface only, or no mining damage.

Adult presence does not ameliorate juvenile feeding challenges in a leaf-footed bug
<p>Herbivores often grapple with structural defenses in their host plants, which may pose especially difficult challenges for juveniles due to their underdeveloped feeding morphology. The degree to which juvenile herbivore survival is limited by structural defenses as well as the strategies used to overcome them are not well understood. We hypothesized that juveniles benefit from feeding near adults because adults pierce through physical barriers while feeding, enabling juveniles to access nutrients that they otherwise could not. We tested this feeding facilitation hypothesis in the leaf-footed bug Leptoglossus zonatus (<em>Hemiptera</em>: <em>Coreidae</em>). Bugs were raised with an adult or a juvenile conspecific and fed a diet of pecans with or without shells. As predicted, we found that juveniles suffered greater mortality when fed nuts with shells than when fed nuts without shells. Contrary to our expectations, the presence of an adult feeding on the same nut did not lessen this effect. Therefore, the presence of an adult does not ameliorate the feeding difficulties faced by juvenile <em>L. zonatus</em>, despite evidence for feeding facilitation in related insect species. This study adds to our understanding of how host plant defenses can limit the survival of even highly generalist herbivores.</p>
