Data for: A linear response framework for simulating bosonic and fermionic correlation functions on quantum computers
<p>Response functions are a fundamental aspect of physics; they represent the link between experimental observations and the underlying quantum many-body state. However, this link is often under-appreciated, as the Lehmann formalism for obtaining response functions in linear response has no direct link to experiments. Within the context of quantum computing, and by using a linear response framework, we restore this link by making the experiment an inextricable part of the quantum simulation. This method can be frequency- and momentum-selective, avoids limitations on operators that can be directly measured, and is ancilla-free. As prototypical examples of response functions, we demonstrate that both bosonic and fermionic Green's functions can be obtained, and apply these ideas to the study of a charge-density-wave material on {\emph{ibm\_auckland}}. The linear response method provides a robust framework for using quantum computers to study systems in physics and chemistry.</p>

Data from: A comparative study of body size evolution in moths: Evidence of correlated evolution with feeding and phenology-related traits
<p>Interspecific variation in body size is one of the most popular topics in comparative studies. Despite recent advances, little is still known about the patterns and processes behind the evolution of body size in insects. Here, we used a robust data set comprising all geometrid moth species occurring in Northern Europe to examine the evolutionary associations involving body size and several life-history traits under an explicitly phylogenetic framework. We provided new insights into the interactive effects of life-history traits on body size and evidence of correlated evolution. We further established the sequence of trait evolution linking body size with the life-history traits correlated with it. We found that most (but not all) of the studied life-history traits, to some extent, interfered with interspecific variation in body size, but interactive effects were uncommon. Both bi- and multivariate phylogenetic analyses indicated that larger species tend to be nocturnal flyers, overwinter in the larval stage, feed on the foliage of trees rather than herbs, and have a generalist feeding behavior. We found evidence of correlated evolution involving body size with overwintering stage, host-plant growth form, and dietary specialization. The examination of evolutionary transitions within the correlated models signaled that overwintering as larvae preceded the evolution of large sizes, as did feeding on tree foliage and the generalist feeding behavior. By showing that both body size and all life-history traits correlated with it evolve at very slow rates, we caution against uncritical attempts to propose causal explanations for respective associations based on contemporary ecological settings.</p>

Data from: Correlated evolution of conspicuous coloration and burrowing in crayfish
<p>Conspicuous colors have fascinated biologists for centuries, leading to research on the evolution and functional significance of color traits. In many cases, research suggests that many conspicuous colors are adaptive and serve some function in sexual or aposematic signaling. In other cases, a lack of evidence for the adaptive value of conspicuous colors troubles biologists, such as within organisms that live underground and are rarely exposed to the surface. Here, we use phylogenetic comparative methods to investigate color evolution throughout freshwater crayfishes that vary in burrowing ability. Within the taxa we analyzed, conspicuous colors have evolved independently over 50 times; and these conspicuous colors are more common in semi-terrestrial crayfishes that construct extensive burrows. The intuitive, but not evolutionary-justified assumption when presented these results is to assume that these colors are adaptive. But contrary to this intuition, we discuss the hypothesis that coloration in crayfish is neutral. Supporting these ideas, small population sizes and reduced gene flow within semi-terrestrial burrowing crayfishes may lead to fixation in color-phenotype mutations. Overall, our work brings into question the traditional view of animal coloration as a perfectly adapted phenotype.</p>

Positive correlation between Ammospiza caudacuta (Saltmarsh Sparrow) capture and productivity supports use of a novel rapid assessment monitoring protocol
<p>Salt marshes in the northeastern United States provide critical breeding habitat for tidal marsh specialist birds like the Saltmarsh Sparrow (Ammospiza caudacuta). The Saltmarsh Sparrow population has declined by nine percent annually, necessitating immediate conservation actions for this vulnerable species. However, estimating species vital rates across a large geographic region is logistically challenging and cost prohibitive. Therefore, we developed and tested a rapid assessment monitoring protocol focused on reproductive metrics to enhance future conservation planning.</p> <p>We used three years of intensive demographic data from 12 sites to estimate daily nest survival, nest period success, fledglings produced per female, and successful broods per female. We implemented the rapid assessment protocol co-located at intensive sites in the same years to estimate the number of captured females and juveniles. We used Pearson's correlation analyses to determine the association of intensive metrics with rapid metrics. We found that the sum of Saltmarsh Sparrow female and juvenile captures was positively correlated with daily nest survival, nest period success, fledglings produced per female, and successful broods per female. Our results demonstrate that fixed-effort mist-netting from our rapid assessment protocol is an informative and time-efficient sampling method that can aid in making informed management decisions related to Saltmarsh Sparrow conservation.</p>
