Adherence to Menzerath’s Law is the exception (not the rule) in three duetting primate species

Dena Clink & Allison Lau
Across diverse systems including language, music, and genomes, there is a tendency for longer sequences to contain shorter constituents; this phenomenon is known as Menzerath’s law. Whether Menzerath’s law is a universal in biological systems, is the result of compression (wherein shortest possible strings represent the maximum amount of information) or emerges from an inevitable relationship between sequence and constituent length remains a topic of debate. In nonhuman primates, the vocalizations of geladas, male gibbons,...

Unmapping the Caribbean: Toward a Digital Praxis of Archipelagic Sounding

Tao Leigh Goffe
Tackling the conceptual grounds of how maps have been deployed as tools of imperial capitalist extraction, this essay critiques how the two-dimensional visualization of land has traditionally flattened the racial entanglement of the Caribbean archipelago. It explores how born-digital cartography can be used to open up a new sensory possibility for understanding space amplified by sonic and video technologies. The author embarked on the digital project *Unmapping the Caribbean* with her students and a team...

Variation in host home range size decreases rabies vaccination effectiveness by increasing the spatial spread of rabies virus

Katherine McClure, Amy Gilbert, Richard Chipman, Erin Rees & Kim Pepin
1. Animal movement influences the spatial spread of directly-transmitted wildlife disease through host-host contact structure. Wildlife disease hosts vary in home range-associated foraging and social behaviors, which may increase the spread and intensity of disease outbreaks. The consequences of variation in host home range movement and space use on wildlife disease dynamics are poorly understood, but could help to predict disease spread and determine more effective disease management strategies. 2. We developed a spatially-explicit individual-based...

Data from: Landscape simplification shapes pathogen prevalence in plant-pollinator networks

Laura Figueroa, Heather Grab, Wee Hao Ng, Christopher Myers, Peter Graystock, Quinn McFrederick & Scott McArt
Species interaction networks, which play an important role in determining pathogen transmission and spread in ecological communities, can shift in response to agricultural landscape simplification. However, we know surprisingly little about how landscape simplification-driven changes in network structure impact epidemiological patterns. Here, we combine mathematical modeling and data from eleven bipartite plant-pollinator networks observed along a landscape simplification gradient to elucidate how changes in network structure shape disease dynamics. Our empirical data show that landscape...

Coalescent-based species delimitation is sensitive to geographic sampling and isolation by distance

Nicholas Mason, Nicholas Fletcher, Brian Gill, Chris Funk & Kelly Zamudio
Species are a fundamental unit of biodiversity that are delimited via genetic data and coalescent-based methods with increasing frequency. Despite the widespread use of coalescent-based species delimitation, we do not fully understand the sensitivity of these methods to potential sources of bias and violations of their underlying assumptions. One implicit assumption of coalescent-based species delimitation is that geographic sampling is adequate and representative of genetic variation among populations within the lineage of interest. Yet exhaustive...

A genome-wide association study of deafness in three canine breeds

Jessica Hayward, Maria Kelly-Smith, Adam Boyko, Louise Burmeister, Luisa De Risio, Cathryn Mellersh, Julia Freeman & George Strain
Congenital deafness in the domestic dog is usually related to the presence of white pigmentation, which is controlled primarily by the piebald locus on chromosome 20 and also by merle on chromosome 10. Pigment-associated deafness is also seen in other species, including cats, mice, sheep, alpacas, horses, cows, pigs, and humans, but the genetic factors determining why some piebald or merle dogs develop deafness while others do not have yet to be determined. Here we...

Data from: Mast seeding patterns are asynchronous at a continental scale

Jalene LaMontagne, Ian Pearse, David Greene & Walter Koenig
Resource pulses are rare events with a short duration and high magnitude that drive the dynamics of both plant and animal populations and communities. Mast seeding is perhaps the most common type of resource pulse that occurs in terrestrial ecosystems, is characterized by the synchronous and highly variable production of seed crops by a population of perennial plants, is widespread both taxonomically and geographically, and is often associated with nutrient scarcity. The rare production of...

Spatial point pattern analysis of traces (SPPAT): an approach for visualizing and quantifying site-selectivity patterns of drilling predators

Alexis Rojas, Gregory Dietl, Michal Kowalewski, Roger W. Portell, Austin Hendy & Jason Blackburn
Site-selectivity analysis in drilling predation may provide useful behavioral information of a predator interacting with its prey. However, traditional approaches exclude some spatial information (i.e., oversimplified trace position) and are dependent on the scale of analysis (e.g., arbitrary grid system used to divide the prey skeleton into sectors). Here we introduce the spatial point pattern analysis of traces (SPPAT), an approach for visualizing and quantifying the distribution of traces on shelled invertebrate prey, which includes...

Disentangling the assembly mechanisms of ant cuticular bacterial communities of two Amazonian ant species sharing a common arboreal nest

Caroline Birer, Corrie S. Moreau, Niklas Tysklind, Lucie Zinger & Christophe Duplais
Bacteria living on the cuticle of ants are generally studied for their protective role against pathogens, especially in the clade of fungus-growing ants. However, little is known of the diversity of cuticular bacteria in other ant host species, as well as of the mechanisms leading to the composition of these communities. Here, we used 16S rRNA gene amplicon sequencing to study the influence of host species, species interactions, and the pool of bacteria from the...

Vermivora photographs in plumage genomic study

Marcella Baiz, Gunnar Kramer, Henry Streby, Scott Taylor, Irby Lovette & David Toews
Hybrids with different combinations of traits can be used to identify the genomic regions that underlie phenotypic characters important to species identity and recognition. Here we explore links between genomic and plumage variation in Blue-winged Warbler x Golden-winged Warbler hybrids, which have traditionally been categorized into two discrete types. "Lawrence’s Warbler" hybrids are very yellow overall, similar to Blue-winged Warblers, but exhibit the black throat patch and face mask of Golden-winged Warblers. "Brewster’s Warbler" hybrids...

Plant volatiles mediate evolutionary interactions between plants and tephritid flies and are evolutionarily more labile than non-volatile defenses

Hua Wang, Wenlong Zhou, Zhao Li, Karl Niklas & Shucun Sun
1. Studies show that plant defenses influence the host-use of herbivores and tend to be evolutionarily more labile than herbivore traits (e.g., feeding preferences). However, all previous studies have focused exclusively on non-volatile plant defenses thereby overlooking the roles of plant volatiles. 2. We hypothesized that volatiles are equally important determinants of herbivore host-use and are evolutionarily more labile than herbivore traits. To test these hypotheses, the following experiments were conducted. 3. We identified the...

Genomic differentiation and local adaptation on a microgeographic scale in a resident songbird

Jennifer Walsh, Stepfanie Aguillon, Yvonne Chan, Peter Arcese, Phred Benham, Irby Lovette & Chloe Mikles
Elucidating forces capable of driving species diversification in the face of gene flow remains a key goal in evolutionary biology. Song sparrows, Melospiza melodia, occur as 25 subspecies in diverse habitats across North America, are among the continent’s most widespread vertebrate species, and are exemplary of many highly variable species for which the conservation of locally adapted populations may be critical to their range-wide persistence. We focus here on six morphologically distinct subspecies resident in...

Golden-winged Warbler post-fledging movement and stand-scale habitat selection

Cameron Fiss, Darin McNeil, Amanda Rodewald, Joseph Duchamp & Jeffery Larkin
Our understanding of songbird habitat needs during the breeding season stems largely from studies of nest success. However, growing evidence shows that nesting habitat and post-fledging habitat often differ. Management guidelines for declining species need to be revaluated and updated to account for habitat shifts that may occur across the full breeding cycle. The Golden-winged Warbler (Vermivora chrysoptera) is a declining songbird species for which best management practices (BMPs) are based overwhelmingly on nesting habitat....

Comparative transcriptomics of a monocotyledonous geophyte reveals shared molecular mechanisms of underground storage organ formation

Carrie Tribble, Jesús Martínez-Gómez, Fernando Alzate-Guarín, Carl Rothfels & Chelsea Specht
Many species from across the vascular plant tree-of-life have modified standard plant tissues into tubers, bulbs, corms, and other underground storage organs (USOs), unique innovations which allow these plants to retreat underground. Our ability to understand the developmental and evolutionary forces that shape these morphologies is limited by a lack of studies on certain USOs and plant clades; Bomarea multiflora (Alstroemeriaceae) fills a key gap in our understanding of USO molecular development as the first...

Data for: Gene tree estimation error with ultraconserved elements: An empirical study on Pseudapis bees

Silas Bossert
Summarizing individual gene trees to species phylogenies using two-step coalescent methods is now a standard strategy in the field of phylogenomics. However, practical implementations of summary methods suffer from gene tree estimation error, which is caused by various biological and analytical factors. Greatly understudied is the choice of gene tree inference method and downstream effects on species tree estimation for empirical data sets. To better understand the impact of this method choice on gene and...

Data from: Assessing avian diversity and community composition along a successional gradient in traditional Lacandon Maya agroforests

Tomasz B. Falkowski, José Raúl Vázquez Pérez, Adolfo Chankin, Atzin Campos, José Luis Rangel, Jonathan B. Cohen & Stewart A.W. Diemont
Evidence regarding the ability of agroforests to conserve biological diversity has been mixed; they tend to maintain avian communities with species richness similar to that of undisturbed forest ecosystems but generally do not completely preserve community composition. Using a combination of occupancy modeling and non-metric multidimensional scaling on point-count data, we assessed changes in avian community diversity and composition along a successional gradient in traditional Lacandon Maya agroforests and compared them to protected areas in...

Data from: A meta-analysis of global avian survival across species and latitude

Micah Scholer, Matt Strimas-Mackey & Jill Jankowski
Tropical birds are thought to be longer lived than many temperate species. We explored the idea of higher survival at tropical latitudes and whether extrinsic climate factors and intrinsic traits helped explain this pattern using a meta-analytical approach. The dataset consists of 949 estimates from 204 studies of avian survival from both New World and Old World biogeographical realms.

Polyethylene upcycling to long-chain alkylaromatics by tandem hydrogenolysis/aromatization

Fan Zhang, Manhao Zeng, Ryan Yappert, Jiakai Sun, Yu-Hsuan Lee, Anne LaPointe, Baron Peters, Mahdi Abu-Omar & Susannah Scott
The current scale of plastics production and the accompanying waste disposal problems represent a largely untapped opportunity for chemical upcycling. Tandem catalytic conversion by Pt/g-Al2O3 converts various polyethylene grades in high yields (up to 80 wt%) to low molecular-weight liquid/wax products, in the absence of added solvent or H2, with little production of light gases. The major components are valuable long-chain alkylaromatics and alkylnaphthenes (average ca. C30, Ð = 1.1). Coupling exothermic hydrogenolysis with endothermic...

Data from: How gut microbiome interactions affect nutritional traits of Drosophila melanogaster

, Grace Peters-Schulze, Jingwei Cai, Andrew D. Patterson & Angela E. Douglas
Most research on the impact of the gut microbiome on animal nutrition is designed to identify the effects of single microbial taxa and single metabolites of microbial origin, without considering the potentially complex network of interactions among co-occurring microorganisms. Here, we investigate how different microbial associations and their fermentation products affect host nutrition, using Drosophila melanogaster colonized with three gut microorganisms (the bacteria Acetobacter fabarum and Lactobacillus brevis and the yeast Hanseniaspora uvarum) in all...

Experimental evidence that acorn woodpeckers recognize relationships among third parties no longer living together

Michael Pardo, Eric Walters & Walter Koenig
Triadic awareness, or knowledge of the relationships between others, is essential to navigating many complex social interactions. While some animals maintain relationships with former group members post-dispersal, recognizing cross-group relationships between others may be more cognitively challenging than simply recognizing relationships between members of a single group because there is typically much less opportunity to observe interactions between individuals that do not live together. We presented acorn woodpeckers (Melanerpes formicivorus), a highly social species, with...
