Both consumptive and non-consumptive effects of predators impact mosquito populations and have implications for disease transmission

Marie C Russell, Catherine M Herzog, Zachary Gajewski, Chloe Ramsay, Fadoua El Moustaid, Michelle V Evans, Trishna Desai, Nicole L Gottdenker, Sara L Hermann, Alison G Power & Andrew C McCall
Predator-prey interactions influence prey traits through both consumptive and non-consumptive effects, and variation in these traits can shape vector-borne disease dynamics. Meta-analysis methods were employed to generate predation effect sizes by different categories of predators and mosquito prey. This analysis showed that multiple families of aquatic predators are effective in consumptively reducing mosquito survival, and that the survival of Aedes, Anopheles, and Culex mosquitoes is negatively impacted by consumptive effects of predators. Mosquito larval size...

Mountain lions reduce movement, increase efficiency during the COVID-19 shutdown

John Benson, Heather Abernathy, Jeff Sikich & Seth Riley
Wildlife strongly alter behavior in response to human disturbance; however, fundamental questions remain regarding the influence of human infrastructure and activity on animal movement. The Covid-19 pandemic created a natural experiment providing an opportunity to evaluate wildlife movement during a period of greatly reduced human activity. Speculation in scientific reviews and the media suggested that wildlife might be increasing movement and colonizing urban landscapes during pandemic slowdowns. However, theory predicts that animals should move and...

Bird Frugivore Abundance data from: Applied nucleation facilitates tropical forest recovery

Karen D. Holl, J. Leighton Reid, Rebecca J. Cole, Federico Oviedo‐Brenes, Juan A. Rosales & Rakan A. Zahawi
Applied nucleation, mostly based upon planting tree islands, has been proposed as a cost‐effective strategy to meet ambitious global forest and landscape restoration targets. We review results from a 15‐year study, replicated at 15 sites in southern Costa Rica, that compares applied nucleation to natural regeneration and mixed‐species tree plantations as strategies to restore tropical forest. We have collected data on planted tree survival and growth, woody vegetation recruitment and structure, seed rain, litterfall, epiphytes,...

Supplementary material: How should functional relationships be evaluated using phylogenetic comparative methods? A case study using metabolic rate and body temperature

Josef Uyeda, Nic Bone, Sean McHugh, Jonathan Rolland & Matthew Pennell
Phylogenetic comparative methods are often used to test functional relationships between traits. However, million-year macroevolutionary observational datasets cannot definitively prove causal links between traits --- correlation does not equal causation and experimental manipulation over such timescales is impossible. While this caveat is widely understood, it is far less appreciated that different phylogenetic approaches make different causal assumptions about the functional relationships of traits. In order to make meaningful inferences, it is critical that our statistical...

Dancing bees evaluate central urban forage resources as superior to agricultural land

Ellouise Leadbeater, Ash Samuelson & Roger Schuerch
Recent evidence suggests that flower-rich areas within cities could play an important role in pollinator conservation, but direct comparison of floral resources within agricultural and urban areas has proved challenging to perform over large scales. Here we use the waggle dances of honeybees (Apis mellifera L.) to perform large-scale landscape surveys at heavily urban or agricultural sites for a key pollinator of wild and crop plants. We analyzed 2827 dances that were performed by 20...

Host traits and environment interact to drive persistence of bat populations impacted by white-nose syndrome

Alexander Grimaudo, Joseph Hoyt, Steffany Yamada, Carl Herzog, Alyssa Bennett & Kate Langwig
Emerging infectious diseases have resulted in severe population declines across diverse taxa. In some instances, despite attributes associated with high extinction risk, disease emergence and host declines are followed by host stabilization for unknown reasons. While host, pathogen, and the environment are recognized as important factors that interact to determine host-pathogen coexistence, they are often considered independently. Here, we use a translocation experiment to disentangle the role of host traits and environmental conditions in driving...

Data For: The developing bird pelvis passes through ancestral Archosaurian and Dinosaurian conditions

Christopher Griffin, João Botelho, Michael Hanson, Matteo Fabbri, Daniel Smith-Paredes, Ryan Carney, Mark Norell, Shiro Egawa, Stephen Gatesy, Timothy Rowe, Ruth Elsey, Sterling Nesbitt & Bhart-Anjan Bhullar
Living birds (Aves) have bodies dramatically modified from the ancestral reptilian condition. The avian pelvis in particular experienced dramatic changes during the transition from early archosaurs to living birds. This stepwise transformation is well documented by an excellent fossil record; however, the ontogenetic alterations that underly it are less well-understood. We used embryological imaging techniques to examine the morphogenesis of avian pelvic tissues in three dimensions, allowing direct comparison with the fossil record. Many ancestral...

1/ Theories and definitions

Patricia , Marietta Radomska, Nina Lykke, Ida Hillerup Hansen, Philip Olson & Nicholas Manganas
This is part 1 of 6 of the dossier What Do We Talk about when We Talk about Queer Death?, edited by M. Petricola. The contributions collected in this article sit at the crossroads between thanatology and queer theory and tackle questions such as: how can we define queer death studies as a research field? How can queer death studies problematize and rethink the life-death binary? Which notions and hermeneutic tools could be borrowed from...

Data from: Inter-annual climate variation influences nest initiation date and nest productivity of the Red-cockaded Woodpecker at the northwestern edge of its range

Matthew Fullerton, Jeffrey Walters, Rodney Will & Scott Loss
Climate change, including directional shifts in weather averages and extremes and increased inter-annual weather variation, is influencing demograhy and distributions for many bird species. We examined how temperature and precipitation coinciding with multiple nesting seasons affected overall nesting success and productivity for two red-cockaded woodpecker (Dryobates borealis, RCW) populations at the species' northwestern range periphery. We used 26 years of nesting data (1991-2016) from the two RCW populations to determine if inter-annual weather variation has...

Data from: Detailed characterization of the UMAMITs proteins provides insight into their evolution, amino acid transport properties, and role in the plant

Guillaume Pilot, Chengsong Zhao, Rejane Pratelli, Bret Shelley, Shi Yu & Eva Collakova
Amino acid transporters play a critical role in distributing amino acids within the cell compartments and between the plant organs. Despite this importance, relatively few amino acid transporter genes have been characterized and their role elucidated with certainty. Two main families of proteins encode amino acid transporters in plants: the Amino Acid-Polyamine-Organocation superfamily, containing mostly importers, and the Usually Multiple Acids Move In and out Transporter family, apparently encoding exporters, totaling 63 and 44 genes...

Public food forest opportunities and challenges in small municipalities

Sarah Coffey, John Munsell, Rico Hübner & Curtis Friedel
The opportunities and challenges associated with public food forest initiatives in small municipalities are understudied compared to large metropolitan counterparts. Research in small population centers is needed to identify and understand factors affecting the growth of public food forests where resources more commonly available in cities often are lacking. To study these factors, we surveyed mayors in Virginia, United States serving communities with populations under 25,000. Out of 176 mayors who received a paper survey...

Data: Diversity-production relationships of fish communities in freshwater stream ecosystems

Bonnie Myers
Ecological relationships between species richness and biomass production are increasingly thought to be pervasive across the globe. Yet diversity-production relationships have not been explored extensively for freshwater fish communities even though fisheries production provides key services to humans. Our aim was to evaluate the diversity-production relationship for fish communities inhabiting freshwater streams across the Appalachian Mountain range and examine how diversity-production relationships varied across streams possessing different thermal signatures. Our study area included 25 freshwater...

Ediacara growing pains: Modular addition and development in Dickinsonia costata

Scott Evans, James G. Gehling, Douglas Erwin & Mary Droser
Constraining patterns of growth using directly observable and quantifiable characteristics can reveal a wealth of information regarding the biology of the Ediacara Biota – the oldest macroscopic, complex community forming organisms in the fossil record. However, these rely on individuals captured at an instant in time at various growth stages, and so different interpretations can be derived from the same material. Here we leverage newly discovered and well-preserved Dickinsonia costata Sprigg 1947 from South Australia,...

eDNA metabarcoding as a means to assess distribution of subterranean fish communities: Iranian blind cave fishes as a case study

Iraj Hashemzadeh Segherloo, Seyedeh Narjes Tabatabaei, Eisa Abdolahi-Mousavi, Cecilia Hernandez, Eric Normandeau, Martin Laporte, Brian Boyle, Mohsen Amiri, Nabiallah GhaedRahmati, Eric Hallerman & Louis Bernatchez
One of the most important steps in conservation of the subterranean life forms is to decipher their distribution and ecology, which is challenging using traditional approaches. Development of an environmental DNA (eDNA) assay provides an efficient means for discovering and monitoring subterranean life forms. In this study, the distribution of three Iranian blind cave fish species (blind Iran cave barb Garra typhlops, blind Lorestan cave barb Garra lorestanensis, and blind cave loach Eidinemacheilus smithi) was...

"A detail-rich, ethnographically informed agent-based model of a Nepalese smallholder village that was originally created for the purpose of studying the impact of multiple stressors on mountain communities, but which can potentially be adapted to serve other purposes. The model was created in NetLogo 5.0.5 but additionally calls on R scripts and .CSV inputs that are included in the package. Example R scripts for conducting analysis of model outputs are also included, along with example...

Spatial personalities: a meta-analysis of consistent individual differences in spatial behavior

Erica Stuber, Ben Carlson & Brett Jesmer
Individual variation in behavior, particularly consistent among-individual differences (i.e., personality), has important ecological and evolutionary implications for population and community dynamics, trait divergence, and patterns of speciation. Nevertheless, individual variation in spatial behaviors, such as home range behavior, movement characteristics, or habitat use has yet to be incorporated into the concepts or methodologies of ecology and evolutionary biology. To evaluate evidence for the existence of consistent among-individual differences in spatial behavior – which we refer...

Data from: Host population dynamics in the face of an evolving pathogen

Wesley Hochachka, Andrew Dobson, Dana Hawley & André Dhondt
1. Interactions between hosts and pathogens are dynamic at both ecological and evolutionary levels. In the resultant “eco-evolutionary dynamics” ecological and evolutionary processes affect each other. For example, the house finch (Haemorhous mexicanus) and its recently-emerged pathogen, the bacterium Mycoplasma gallisepticum, form a system in which evidence suggests that changes in bacterial virulence through time enhance levels of host immunity in ways that drive the evolution of virulence in an arms race. 2. We use...

Climatic niche shifts in 815 introduced plant species affect their predicted distributions: Data and scripts

Daniel Atwater & Jacob Barney
Aim: Introduced species often occupy different climates in their introduced than their native range, but to what degree do such ‘climatic niche shifts’ interfere with our ability to predict invasions? Answering this question is crucial if we are to understand the threat invasive species pose to human and natural systems, especially given the ever increasing use of species distribution models as tools for invasive species risk assessment and management. Here we investigated how strongly climatic...

Toucan dispersal of large-seeded trees

J. Leighton Reid
Large-seeded, animal-dispersed (LSAD) trees include some of the most valuable and threatened species in the tropics, but they are chronically underrepresented in regenerating forests. Toucans disperse many LSAD species, so attracting toucans to regenerating forests should help re-establish more diverse tree communities. We ask: (1) What constitutes suitable toucan habitat in premontane southern Costa Rica? (2) How much do small-scale restoration strategies influence toucan visitation compared to landscape-scale habitat suitability outside of restoration sites? (3)...

Incubation temperature as a constraint on clutch size evolution

Sydney Hope, Sarah DuRant, John Hallagan, Michelle Beck, Robert Kennamer & William Hopkins
1. Elucidating factors that limit the number of offspring produced is fundamental to understanding life-history evolution. Here, we examine the hypothesis that parental ability to maintain an optimal physical developmental environment for all offspring constrains clutch size via effects on offspring quality. 2. Experimental laboratory studies of birds have shown that a <1°C difference in average incubation temperature has diverse effects on fitness-related post-hatching offspring phenotypes. Thus, the inability of parents to maintain optimal incubation...

Larval A. bishopi microsatellite data from: Metapopulation genetics of endangered reticulated flatwoods salamanders (Ambystoma bishopi) in a dynamic and fragmented landscape

Alexander Wendt, Carola Haas, Thomas Gorman & James Roberts
The dataset consists of 9 microsatellite markers used to analyze reticulated flatwoods salamanders' (Ambystoma bishopi) population structure on Eglin AFB. Samples came from various breeding ponds and allele sizes were scored using GeneMapper (GeneMapper v4.0; Applied Biosystems). Data was collected via allele scoring in GeneMapper by two independent researchers. Allele sizes for each individual have been re-formatted for various programs using the microsatellite Add-in in Excel as well as by using the GenAlEx extension in...
