Data from: A test of the eavesdropping avoidance hypothesis as an explanation for the structure of low amplitude aggressive signals in the song sparrow

Joseph M. Niederhauser, Adrienne L. DuBois, William A. Searcy, Stephen Nowicki & Rindy C. Anderson
Low amplitude signals function in private exchanges of information between signalers and nearby receivers. The eavesdropping avoidance hypothesis proposes that selection favors quiet threat signals in order to avoid the costs of eavesdroppers. If true, then selection should favor other acoustic traits in addition to low amplitude that lead to quiet signals transmitting less effectively through the environment compared to broadcast signals. The “warbled” soft songs of male song sparrows differ from “crystallized” soft songs...

Data from: Microbial mitigation-exacerbation continuum: a novel framework for microbiome effects on hosts in the face of stress

Aaron S. David, Khum B. Thapa-Magar & Michelle E. Afkhami
A key challenge to understanding microbiomes and their role in ecological processes is contextualizing their effects on host organisms, particularly when faced with environmental stress. One influential theory, the Stress Gradient Hypothesis, might predict that the frequency of positive interactions increases with stressful conditions such that microbial taxa would mitigate harmful effects on host performance. Yet, equally plausible is that microbial taxa could exacerbate these effects. Here, we introduce the "Mitigation-Exacerbation Continuum" as a novel...

Data from: Cooperation and coexpression: how coexpression networks shift in response to multiple mutualists

Sathvik X. Palakurty, John R. Stinchcombe & Michelle E. Afkhami
A mechanistic understanding of community ecology requires tackling the nonadditive effects of multispecies interactions, a challenge that necessitates integration of ecological and molecular complexity-- namely moving beyond pairwise ecological interaction studies and the ‘gene at a time’ approach to mechanism. Here, we investigate the consequences of multispecies mutualisms for the structure and function of genome-wide coexpression networks for the first time, using the tractable and ecologically-important interaction between legume Medicago truncatula, rhizobia, and mycorrhizal fungi....

Data from: Symbiotic immuno-suppression: is disease susceptibility the price of bleaching resistance?

Daniel G. Merselis, Diego Lirman & Mauricio Rodriguez-Lanetty
Accelerating anthropogenic climate change threatens to destroy coral reefs worldwide through the processes of bleaching and disease. These major contributors to coral mortality are both closely linked with thermal stress intensified by anthropogenic climate change. Disease outbreaks typically follow bleaching events, but a direct positive linkage between bleaching and disease has been debated. By tracking 152 individual coral ramets through the 2014 mass bleaching in a South Florida coral restoration nursery, we revealed a highly...

Data from: The changing nature of collaboration in tropical ecology and conservation

Timothy M. Perez & J. Aaron Hogan
Collaboration can improve conservation initiatives through increases in article impact and by the building scientific understating required for conservation practice. We investigated temporal trends in collaboration in the tropical ecology and conservation literature by examining patterns of authorship for 2,271 articles published from 2000 to 2016 in Biotropica and the Journal of Tropical Ecology. Consistent with trends in other studies and scientific disciplines, we found that the mean number of authors per article increased from...

Data from: Rare long-distance dispersal of a marine angiosperm across the Pacific Ocean

Timothy M. Smith, Paul H. York, Bernardo R. Broitman, Martin Thiel, Graeme C. Hays, Erik Van Sebille, Nathan F. Putman, Peter I. Macreadie & Craig D. H. Sherman
Aim: Long-distance dispersal (LDD) events occur rarely but play a fundamental role in shaping species biogeography. Lying at the heart of island biogeography theory, LDD relies on unusual events to facilitate colonisation of new habitats and range expansion. Despite the importance of LDD, it is inherently difficult to quantify due to the rarity of such events. We estimate the probability of LDD of the seagrass Heterozostera nigricaulis, a common Australian species, across the Pacific Ocean...

Data from: Early development of vocal interaction rules in a duetting songbird

Karla D. Rivera-Cáceres, Esmeralda Quirós-Guerrero, Marcelo Araya-Salas, Christopher N. Templeton & William A. Searcy
Exchange of vocal signals is an important aspect of animal communication. Although birdsong is the premier model for understanding vocal development, the development of vocal interaction rules in birds and possible parallels to humans have been little studied. Many tropical songbirds engage in complex engage in vocal interactions in the form of duets between mated pairs. In some species duets show precise temporal coordination and follow rules (duet codes) governing which song type one bird...

Survey results of white (Carcharodon carcharias) and sevengill sharks (Notorynchus cepedianus) at Seal Island in False Bay, South Africa between 2000 and 2018

Chris Fallows, Monique Fallows, Lacey Williams & Neil Hammerschlag
This dataset is associated to the article “Disappearance of white sharks leads to the novel emergence of an allopatric apex predator, the sevengill shark” by Hammerschlag et al. (2018), published in Nature Scientific Reports, https://doi.org/10.1038/s41598-018-37576-6. Specifically, these are the data used to create figures 3,4, and 5 as well as supplementary figures S1, S2, and S3. These data are the results of monitoring between 2000 and 2018 of white shark (Carcharodon carcharias) abundance patterns (N=6,333...

Data from: Morphological adaptations for relatively larger brains in hummingbird skulls

Diego Ocampo, Gilbert Barrantes & J. Albert C. Uy
A common allometric pattern called Haller’s Rule states that small species have relatively larger brains and eyes than larger species of the same taxonomic group. This pattern imposes drastic structural changes and energetic costs on small species to produce and maintain a disproportionate amount of nervous tissue. Indeed, several studies have shown the significant metabolic costs of having relatively larger brains; however, little is known about the structural constraints and adaptations required for housing these...

Data from: Automated analysis of long-term grooming behavior in Drosophila using a k-nearest neighbors classifier

Bing Qiao, Chiyuan Li, Victoria W. Allen, Mimi M. Shirasu-Hiza & Sheyum Syed
Despite being pervasive, the control of programmed grooming is poorly understood. We addressed this gap by developing a high-throughput platform that allows long-term detection of grooming in Drosophila melanogaster. In our method, a k-nearest neighbors algorithm automatically classifies fly behavior and finds grooming events with over 90% accuracy in diverse genotypes. Our data show that flies spend ~13% of their waking time grooming, driven largely by two major internal programs. One of these programs regulates...

Data from: Pink shrimp Farfantepenaeus duorarum spatiotemporal abundance trends along an urban, subtropical shoreline slated for restoration

Ian C. Zink, Joan A. Browder, Diego Lirman & Joseph E. Serafy
The Biscayne Bay Coastal Wetlands (BBCW) project of the Comprehensive Everglades Restoration Plan (CERP) aims to reduce point-source freshwater discharges and spread freshwater flow along the mainland shoreline of southern Biscayne Bay. These actions will be taken to approximate conditions in the coastal wetlands and bay that existed prior to construction of canals and water control structures. An increase in pink shrimp (Farfantepenaeus duorarum) density to ≥ 2 individuals m-2 during the wet season (i.e.,...

Data from: Regional surveys of macrobenthic shelf invertebrate communities in Onslow Bay, North Carolina, U.S.A.

Carrie L. Tyler & Michał Kowalewski
Despite its importance for quantifying ecosystem responses to environmental and anthropogenic drivers, our understanding of spatial heterogeneity in marine communities remains inadequate. Studies in coastal marine benthic habitats are sparse, and predominantly target single higher taxonomic groups. Here we describe macrobenthic marine invertebrate community surveys from 52 localities in Onslow Bay (Beaufort, North Carolina, U.S.A.), over an extensive geographic area (~200 km2). The data consist of 11,467 individuals, 175 species, and 7 phyla. The data...
