Data from: Host association influences variation at salivary protein genes in the bat ectoparasite Cimex adjunctus

Benoit Talbot, Maarten J. Vonhof, Hugh G. Broders, Brock Fenton & Nusha Keyghobadi
Parasite-host relationships create strong selection pressures that can lead to adaptation and increasing specialization of parasites to their hosts. Even in relatively loose host-parasite relationships, such as between generalist ectoparasites and their hosts, we may observe some degree of specialization of parasite populations to one of the multiple potential hosts. Salivary proteins are used by blood-feeding ectoparasites to prevent hemostasis in the host and maximize energy intake. We investigated the influence of association with specific...

Data from: Reproduction as a bottleneck to treeline advance across the circumarctic forest tundra ecotone

Carissa D. Brown, Geneviève Dufour-Tremblay, Ryan G. Jameson, Steven D. Mamet, Andrew J. Trant, Xanthe J. Walker, Stéphane Boudraeu, Karen A. Harper, Greg H.R. Henry, Luise Hermanutz, Annika Hofgaard, Ludmila Isaeva, G. Peter Kershaw, Jill F. Johnstone & Gregory H. R. Henry
The fundamental niche of many species is shifting with climate change, especially in sub-arctic ecosystems with pronounced recent warming. Ongoing warming in sub-arctic regions should lessen environmental constraints on tree growth and reproduction, leading to increased success of trees colonising tundra. Nevertheless, variable responses of treeline ecotones have been documented in association with warming temperatures. One explanation for time lags between increasingly favourable environmental conditions and treeline ecotone movement is reproductive limitations caused by low...

Data from: Questioning assumptions of trophic behavior in a broadly ranging marine predator guild

Oliver N. Shipley, Jill A. Olin, Mike Power, Robert M. Cerrato, Michael G. Frisk, Robert. M. Cerrato & Michael Power
We evaluated whether existing assumptions regarding the trophic ecology of a poorly-studied predator guild, northwest (NW) Atlantic skates (family: Rajidae), were supported across broad geographic scales. Four hypotheses were tested using carbon (δ13C) and nitrogen (δ15N) stable isotope values as metrics of foraging behavior: 1) species exhibit ontogenetic shifts in habitat and thus display a shift in 13C with differential use of the continental shelf; 2) species exhibit ontogenetic prey shifts (i.e., from smaller to...

Data from: Combinations of reproductive, individual, and weather effects best explain torpor patterns among female little brown bats (Myotis lucifugus)

Nicole K. Besler & Hugh G. Broders
Heterothermic mammals can use torpor, a state of metabolic suppression, to conserve energy during times of limited food and poor environmental conditions. Females may use torpor throughout gestation and lactation; however, there are associated physiological and ecological costs with potential fitness consequences. Previous studies have controlled for, but not quantified the impact of interindividual variation on torpor patterns and understanding this may provide insight on why certain thermoregulatory responses are employed. The objective of this...

Data from: Patterns of nitrogen-fixing tree abundance in forests across Asia and America

Duncan N. L. Menge, Ryan A. Chisholm, Stuart J. Davies, Kamariah Abu Salim, David Allen, Mauricio Alvarez, Norm Bourg, Warren Y. Brockelman, Sarayudh Bunyavejchewin, Nathalie Butt, Min Cao, Wirong Chanthorn, Wei-Chun Chao, Keith Clay, Richard Condit, Susan Cordell, João Batista Da Silva, H. S. Dattaraja, Ana Cristina Segalin De Andrade, Alexandre A. Oliveira, Jan Den Ouden, Michael Drescher, Christine Fletcher, Christian P. Giardina, C. V. Savitri Gunatilleke … & Tak Fung
Symbiotic nitrogen (N)‐fixing trees can provide large quantities of new N to ecosystems, but only if they are sufficiently abundant. The overall abundance and latitudinal abundance distributions of N‐fixing trees are well characterised in the Americas, but less well outside the Americas. Here, we characterised the abundance of N‐fixing trees in a network of forest plots spanning five continents, ~5,000 tree species and ~4 million trees. The majority of the plots (86%) were in America...

The Loss of Playfulness

Janet Jones
How does social distancing affect our sense of self? Our ability to create ourselves? In this article, I explore the value of interacting with strangers for our sense of self and the impact of COVID-19 safety measures on our relationships with others. Specifically, I suggest that strangers can offer us opportunities to try on new identities but that this opportunity is lost as the public realm erodes because of the COVID-19 pandemic.

Analytic dataset informing prediction of subterranean cave and mine ambient temperatures

Meredith McClure, Daniel Crowley, Catherine Haase, Liam McGuire, Nathan Fuller, David Hayman, Cori Lausen, Raina Plowright, Brett Dickson & Sarah Olson
Caves and other subterranean features provide unique environments for many species. The importance of cave microclimate is particularly relevant at temperate latitudes where bats make seasonal use of caves for hibernation. White-nose syndrome (WNS), a fungal disease that has devastated populations of hibernating bats across eastern and central North America, has brought renewed interest in bat hibernation and hibernaculum conditions. A recent review synthesized current understanding of cave climatology, exploring the qualitative relationship between cave...

Risk, Entropy, and the Transformation of Distributions

R. Mark Reesor & Don L. McLeish
The exponential family, relative entropy, and distortion are methods of transforming probability distributions. We establish a link between those methods, focusing on the relation between relative entropy and distortion. Relative entropy is commonly used to price risky financial assets in incomplete markets, while distortion is widely used to price insurance risks and in risk management. The link between relative entropy and distortion provides some intuition behind distorted risk measures such as value-at-risk. Furthermore, distorted risk...

Dataset: Inverse responses of species richness and niche specialization to human development

Martin Jeanmougin, Cari D. Ficken, Jan J.H. Ciborowski & Rebecca C. Rooney
Humans impact biodiversity by altering land use and introducing nonnative species. Yet the extent to which coexistence processes, such as competition and niche shifts, mediate these relationships is not clear. This dataset was used in a study that aims to compare how human development influences wetland plant diversity by examining patterns of species richness, niche specialization, and nonnative species occurrences along a human development gradient. This dataset can be used to analyzed species richness and...

Island biogeography theory and the urban landscape: stopover site selection by the silver-haired bat (Lasionycteris noctivagans)

Liam McGuire & Hannah Adams
Many migratory bats require forested sites for roosting and foraging along their migration path, but increased urbanization and intensive agricultural practices may reduce the availability of stopover sites. Urban forests may provide important stopover habitat, maintaining landscape connectivity in regions where the majority of natural habitat has been cleared for development. Island biogeography theory can be applied to urbanized temperate forest biomes where small urban forests represent islands separated from the larger “mainland” forest. We...

Topological inverse design of fabrication-constrained nanophotonic devices via adaptive projection method

Hao Liang, Qi Wang, Xueguang Yuan, Hao Liu, Jiyu Xu, Yangan Zhang, Kai Liu, Yongqing Huang & Xiaomin Ren
Topology optimization has been widely adopted in the inverse design of nanophotonic devices due to low computational cost, which unfortunately produces intermediate relative permittivity values that fail to meet fabrication constraints. Additionally, the postprocessing required inevitably increases the complexity of the inverse design. In this Letter, we propose an adaptive projection method for topology optimization, in which a two-level hierarchical hyperbolic tangent projection function with linear increment and differentiation was constructed and applied to eliminate...

Extending health systems resilience into communities: a qualitative study with community-based actors providing health services during the COVID-19 pandemic in the Philippines

Victoria Haldane, Warren Dodd, Amy Kipp, Hannah Ferrolino, Kendall Wilson, Danilo Servano, Lincoln L. Lau & Xiaolin Wei
Abstract Background Amidst ongoing calls for increased health systems resilience, gaps remain in our understanding of how health systems can reach further into communities to ensure resilient service delivery. Indeed, public health emergencies caused by infectious hazards reveal both the value and vulnerability of the workforce delivering health services in communities. This study explores ways in which a non-governmental organization (NGO) in the Philippines protected their frontline workforce during the first year of the COVID-19...

Data from: Genus-wide microsatellite primers for the goldenrods (Solidago; Asteraceae)

James B. Beck, John C. Semple, Justin M. Brull, Stacey L. Lance, Mai M. Phillips, Sara B. Hoot & Gretchen A. Meyer
Premise of the study: Microsatellite primers were developed for studies of polyploid evolution, ecological genetics, conservation genetics, and species delimitation in the genus Solidago. Methods and Results: Illumina sequencing of a shotgun library from S. gigantea identified ca. 1900 putative single-copy loci. Fourteen loci were subsequently shown to be amplifiable, single-copy, and variable in a broad range of Solidago species. Conclusions: The utility of these markers both across the genus and in herbarium specimens of...
