Fine-scale spatial patterns of wildlife disease are common and understudied

Gregory Albery, Amy Sweeny, Daniel Becker & Shweta Bansal
1. All parasites are heterogeneous in space, yet little is known about the prevalence and scale of this spatial variation, particularly in wild animal systems. To address this question, we sought to identify and examine spatial dependence of wildlife disease across a wide range of systems. 2. Conducting a broad literature search, we collated 31 such datasets featuring 89 replicates and 71 unique host-parasite combinations, only 51% of which had previously been used to test...

Spatiotemporal variation in drivers of parasitism in a wild wood mouse population

Amy Sweeny, Gregory Albery, Saudamini Venkatesan, Andy Fenton & Amy Pedersen
Host-parasite interactions in nature are driven by a range of factors across several ecological scales, so observed relationships are often context-dependent. Importantly, if these factors vary across space and time, practical sampling limitations can limit or bias inferences, and the relative importance of different drivers can be hard to discern. Here we ask to what degree environmental, host, and within-host influences on parasitism are shaped by spatiotemporal variation. We use a replicated, longitudinal dataset of...

Characterization of Salix nigra floral insect community and activity of three native Andrena bees

Stephen DiFazio, Sandra Simon, Ken Keefover-Ring, Yong-Lak Park, Gina Wimp & Julianne Grady
Salix nigra (black willow) is a widespread tree that hosts many species of polylectic hymenopterans and oligolectic bees of the genus Andrena. The early flowering of S. nigra makes it an important nutritive resource for insects emerging from hibernation. However, since S. nigra is dioecious, not all insect visits will lead to successful pollination. Using both visual observation and pan-trapping we characterized the community of insects that visited S. nigra flowers and assessed differences among...

Empirical tests of habitat selection theory reveal that conspecific density and patch quality, but not habitat amount, drive long-distance immigration in a wild bird

Clark Rushing, Brandt Ryder, Jonathon J. Valente, Scott Sillett & Peter Marra
Individuals that disperse long distances from their natal site must select breeding patches with no prior knowledge of patch suitability. Despite decades of theoretical studies examining which cues dispersing individuals should use to select breeding patches, few empirical studies have tested the predictions of these theories at spatial scales relevant to long-distance dispersal in wild animal populations. Here, we use a novel assignment model based on multiple intrinsic markers to quantify natal dispersal distances of...

Data from: Hatching date influences winter habitat occupancy: examining seasonal interactions across the full annual cycle in a migratory songbird

Michael Akresh, David King & Peter Marra
Birds experience a sequence of critical events during their life cycle, and past events can subsequently determine future performance via carry-over effects. Events during the non-breeding season may influence breeding season phenology or productivity. Less is understood about how events during the breeding season affect individuals subsequently in their life cycle. Using stable carbon isotopes, we examined carry-over effects throughout the annual cycle of prairie warblers (Setophaga discolor), a declining Nearctic-Neotropical migratory passerine bird. In...

A linkage-based genome assembly for the mosquito Aedes albopictus and identification of chromosomal regions affecting diapause

John Boyle, Peter Armbruster, Pasi Rastas, Xin Huang, Austin Garner, Indra Vythilingam & Peter Armbruster
The Asian tiger mosquito, Aedes albopictus, is an invasive vector mosquito of substantial public health concern. The large genome size (~1.19-1.28 Gb by cytofluorometric estimates), comprised of ~68% repetitive DNA sequences, has made it difficult to produce a high-quality genome assembly for this species. We constructed a high-density linkage map for Ae. albopictus based on 111,328 informative SNPs obtained by RNAseq. We then performed a linkage-map anchored reassembly of AalbF2, the genome assembly produced by...

Data for: Many-body thermodynamics on quantum computers via partition function zeros

Akhil Francis, Daiwei Zhu, Cinthia Huerta Alderete, Sonika Johri, Xiao Xiao, James K. Freericks, Christopher Monroe, Norbert M. Linke & Alexander F. Kemper
Partition functions are ubiquitous in physics: they are important in determining the thermodynamic properties of many-body systems, and in understanding their phase transitions. As shown by Lee and Yang, analytically continuing the partition function to the complex plane allows us to obtain its zeros and thus the entire function. Moreover, the scaling and nature of these zeros can elucidate phase transitions. Here we show how to find partition function zeros on noisy intermediate-scale trapped ion...
