Changes in tree community structures in defaunated forests are not driven only by dispersal limitation

Kirstie Hazelwood, C. E. Timothy Paine, Fernando H. Cornejo-Valverde, Elizabeth G. Pringle, Harald Beck & John Terborgh
1. Bushmeat hunting has reduced population sizes of large frugivorous vertebrates throughout the tropics, thereby reducing the dispersal of seeds. This is believed to affect tree population dynamics, and therefore community composition, because the seed dispersal of large-seeded trees depends upon large-bodied vertebrates. 2. We report on a long-running study of the effect of defaunation on a tropical tree community. In three censuses over 11 years, we compared sapling recruitment between a hunted and a...

Functional trait table for mixed-species flocking birds in the Western Andes of Colombia

Harrison Jones & Scott Robinson
These data represent functional traits relevant to the foraging ecology and habitat preferences of mixed-species flock joining bird species from the Western Andes of Colombia. We collected these data based on published data for the species from the Handbook of the Birds Alive online database (del Hoyo et al. 2020), supplemented with additional natural history references were available, with the objective of calculating the functional richness contained in mixed-species flock compositions sampled across a patch...

Vector bionomics and vectorial capacity as emergent properties of mosquito behaviors and ecology

Sean Wu, Penny Hancock, Arnaud Le Menach, Tanya Russell, Thomas Burkot, , Derek Cummings, Kelly Compton, Daniel Citron, John Marshall, Biyonka Liang, Catherine Moyes, Qian Zhang, David Smith, Samson Kiware, Anne Wilson, Thomas Scott, John Henry, Steven Lindsay, Amit Verma & Hector Sanchez C.
Mosquitoes are important vectors for pathogens that infect humans and other vertebrate animals. Some aspects of adult mosquito behavior and mosquito ecology play an important role in determining the capacity of vector populations to transmit pathogens. Here, we re-examine factors affecting the transmission of pathogens by mosquitoes using a new approach. Unlike most previous models, this framework considers the behavioral states and state transitions of adult mosquitoes through a sequence of activity bouts. We developed...

Colony-age-dependent variation in cuticular hydrocarbon profiles in subterranean termite colonies

Johnalyn Gordon, Jan Šobotník & Thomas Chouvenc
Cuticular hydrocarbons (CHCs) have, in insects, important physiological and ecological functions, such as protection against desiccation and as semiochemicals in eusocial taxa, including termites. CHCs are, in termites, known to vary qualitatively and/or quantitatively among species, populations, or seasons. Changes to hydrocarbon profile composition have been linked to varying degrees of aggression between termite colonies, although the variability of results among studies suggests that additional factors might have been involved. One source of variability may...

MHC variation is similar in little brown bats before and after white-nose syndrome outbreak

Xueling Yi, Emily Latch, Deahn Donner, Paula Marquardt, Jonathan Palmer, Michelle Jusino, Jacqueline Frair & Daniel Lindner
White-nose syndrome (WNS), caused by the fungal pathogen Pseudogymnoascus destructans (Pd), has driven alarming declines in North American hibernating bats, such as little brown bat (Myotis lucifugus). During hibernation, infected little brown bats are able to initiate anti-Pd immune responses, indicating pathogen-mediated selection on the major histocompatibility complex (MHC) genes. However, such immune responses may not be protective as they interrupt torpor, elevate energy costs, and potentially lead to higher mortality rates. To assess whether...

Hemipteran defensive odors trigger predictable color biases in jumping spider predators

Michael Vickers & Lisa Taylor
Multimodal warning displays often pair one signal modality (odor) with a second modality (color) to avoid predation. Experiments with bird predators suggest these signal components interact synergistically, with aversive odors triggering otherwise hidden aversions to particular prey colors. In a recent study, this phenomenon was found in a jumping spider (Habronattus trimaculatus), with the defensive odor from a coreid bug (Acanthocephala femorata) triggering an aversion to red. Here, we explore how generalizable this phenomenon is...

Optimal allocation of law enforcement patrol effort to mitigate poaching activities

Bradley Udell, Jennifer Moore, Julien Martin, Ezechiel Turikunkiko & Michel Masozera
Poaching is a global problem causing the decline of species worldwide. Optimizing the efficiency of ranger patrols to deter poaching activity at the lowest possible cost is crucial for protecting species with limited resources. We applied decision analysis and spatial optimization algorithms to allocate efforts of ranger patrols throughout a national park. Our objective was to mitigate poaching activity at or below management risk targets for the lowest monetary cost. We examined this tradeoff by...

Comparative phylogenetics of Papilio butterfly wing shape and size demonstrates independent hindwing and forewing evolution

Hannah Owens, Delano Lewis, Fabien Condamine, Akito Kawahara & Robert Guralnick
The complex forces that shape butterfly wings have long been a subject of experimental and comparative research. Butterflies use their wings for flight, camouflage, mate recognition, warning and mimicry. However, general patterns and correlations among wing shape and size evolution are still poorly understood. We collected geometric morphometric measurements from over 1400 digitized museum specimens of Papilio swallowtails and combined them with phylogenetic data to test two hypotheses: 1) forewing shape and size evolve independently...

Dispersal predicts hybrid zone widths across animal diversity: Implications for species borders under incomplete reproductive isolation

Jay McEntee, J. Gordon Burleigh & Sonal Singhal
Hybrid zones occur as range boundaries for many animal taxa. One model for how hybrid zones form and stabilize is the tension zone model, a version of which predicts that hybrid zone widths are determined by a balance between random dispersal into hybrid zones and selection against hybrids. Here, we examine whether random dispersal and proxies for selection against hybrids (genetic distances between hybridizing pairs) can explain variation in hybrid zone widths across 131 hybridizing...

The magnitude of large-scale tree mortality caused by the invasive pathogen Phytophthora ramorum

Richard Cobb, Sarah Haas, Nicholas Kruskamp, Whalen Dillon, Tedmund Swiecki, David Rizzo, Susan Frankel & Ross Meentemeyer
Forest pathogens are important drivers of tree mortality across the globe but it is exceptionally challenging to gather and build unbiased quantitative models of their impacts, which has resulted in few estimates matching the scale of disease. Here we harness the rare dataset matching the spatial scale of pathogen invasion, host, and disease heterogeneity to estimate infection and mortality for the four most susceptible host species of Phytophthora ramorum, an invasive pathogen that drives the...

Dataset for Body size impacts critical thermal maximum measurements in lizards

Natalie Claunch & Emily Taylor
Understanding the mechanisms behind critical thermal maxima (CTmax, the high body temperature at which neuromuscular coordination is lost) of organisms is central to understanding ectotherm thermal tolerance. Body size is an often overlooked variable that may affect interpretation of CTmax, and consequently, how CTmax is used to evaluate mechanistic hypotheses of thermal tolerance. We tested the hypothesis that body size affects CTmax and its interpretation in two experimental contexts. First, in four Sceloporus species, we...

Forest biomass in subtropical Andes: Plots data

Cecilia Blundo, Agustina Malizia, Lucio R. Malizia & Jeremy W. Lichstein
Forest biomass plays an important role in the global carbon cycle. Therefore, understanding the factors that control forest biomass stocks and dynamics is a key challenge in the context of global change. We analyzed data from 60 forest plots in the subtropical Andes (22-27.5° S and 300-2300 m asl) to describe patterns and identify drivers of aboveground biomass (AGB) stocks and dynamics. We found that AGB stocks remained roughly constant with elevation due to compensating...

Trade-offs between seed size and biotic interactions contribute to coexistence of co-occurring species that vary in fecundity

John Maron, Philip Hahn, Kayrn Hajek & Dean Pearson
Despite theoretical advances, the ecological factors and functional traits that enable species varying in seed size and fecundity to coexist remain unclear. Given inherent fecundity advantages, why don’t small-seeded species dominate communities? In perennial grasslands, we evaluated whether small-seeded species are less tolerant of competition from the community dominant bunchgrass than large-seeded species but also less vulnerable to seed predation by mice. We also explored whether trade-offs involving competitive tolerance include two other functional traits,...

Sex affects immunolabeling for histone 3 K27me3 in the trophectoderm of the bovine blastocyst but not labeling for histone 3 K18ac

Peter Hansen, Luciano Carvalheira, Paula Tribulo & Alan Borges
The mammalian embryo displays sexual dimorphism in the preimplantation period. Moreover, competence of the embryo to develop is dependent on the sire from which the embryo is derived and can be modified by embryokines produced by the endometrium such as colony stimulating factor 2 (CSF2). The preimplantation period is characterized by large changes in epigenetic modifications of DNA and histones. It is possible, therefore, that effects of sex, sire, and embryo regulatory molecules are mediated...

Tempo Data from Broadcast Performances of Giacomo Puccini’s Turandot at the Metropolitan Opera, 1961 – 2009

Joshua Neumann
The works of well-known composers active as recording technology developed and as the recording industry emerged thus make ideal case studies. Giacomo Puccini is uniquely suited to a study of tradition through technological means: he has perhaps the best-documented relationship to advances in technology and the resulting shift in entertainment aesthetics of any composer of this era. Of his twelve operas, Turandot is the only major work whose premiere post-dates the advent of electronically captured...

Data from: Chemical defenses shift with the seasonal vertical migration of a Panamanian poison frog

Edmund W Basham, Ralph A Saporito, Macario González-Pinzón, Angel Romero-Marcucci & Brett R Scheffers
Dendrobatid poison frogs sequester lipophilic alkaloids from their arthropod prey to use as a form of chemical defense. Some dendrobatid frogs seasonally migrate between the leaf litter of the forest floor in the dry season to the canopy in the wet season, which may yield differences in prey (arthropods) and therefore alkaloid availability over space and time. Here, we document a seasonal vertical migration of Andinobates fulguritus (the yellow-bellied poison frog) from ground to canopy...

Generation of a chromosome-scale genome assembly of the insect-repellant terpenoid-producing Lamiaceae species, Callicarpa americana

Data from: Interaction networks of avian mixed-species flocks along elevation in the tropical Andes

Flavia A. Montaño-Centellas
Ecological communities are comprised of species that interact with each other and those interactions ultimately generate community structure. Network theory provides a useful framework to study communities, by simultaneously considering species composition and the interactions among species. In this study, I use mixed-species flocks as model systems to gain insights on community and network structure. Specifically, I use co-occurrence network analyses to explore if avian mixed-species flocks change in richness and composition and/or in network...

A global meta-analysis of temperature effects on marine fishes’ digestion across trophic groups

Nicole Knight, Frederic Guichard & Andrew Altieri
Aim: The temperature constraint hypothesis proposes that marine herbivorous fishes are rare at high latitudes relative to carnivorous fishes because low temperatures impair the digestion of plant material. To test this hypothesis, we compared the effects of temperature on the digestive performance and investment of marine fishes across trophic groups. Location: Global marine ecosystems. Major Taxa Studied: Marine fishes. Methods: We analyzed data from 304 species consuming a range of diets to quantify the effects...

Data from: Leaf-footed bugs possess multiple hidden contrasting color signals, but only one is associated with increased body size

Zachary Emberts, Christine Miller, Chelsea Skojec, Rachel Shepherd & Colette St. Mary
Anti-predatory displays that incorporate hidden contrasting coloration are found in a variety of different animals. These displays are seen in organisms that have drab coloration at rest, but when disturbed reveal conspicuous coloration. Examples include the bright abdomens of mountain katydids and the colorful underwings of hawk moths. Such hidden displays can function as secondary defenses, enabling evasion of a pursuant predator. To begin to understand why some species have these displays while others do...

Data from: Increasing synergistic effects of habitat destruction and hunting on mammals over three decades in the Gran Chaco

Alfredo Romero-Muñoz, Ana Benítez-López, Damaris Zurell, Matthias Baumann, Micaela Camino, Julieta Decarre, Hugo Del Castillo, Anthony Giordano, Bibiana Gómez-Valencia, Christian Levers, Andrew Noss, Veronica Quiroga, Jeffrey Thompson, Ricardo Torres, Marianela Velilla, Andrea Weiler & Tobias Kuemmerle
Habitat destruction and overexploitation are the main threats to biodiversity and where they co-occur, their combined impact is often larger than their individual one. Yet, detailed knowledge of the spatial footprints of these threats is lacking, including where they overlap and how they change over time. These knowledge gaps are real barriers for effective conservation planning. Here, we develop a novel approach to reconstruct the individual and combined footprints of both threats over time. We...

Bat community response to intensification of biomass production for bioenergy across the southeastern United States

Holly Ober, Gavin Jones, Isabel Gottlieb, Shelly Johnson, Lora Smith, Berry Brosi & Robert Fletcher
Human demand for food, fiber, and space is accelerating the rate of change of land cover and land use. Much of the world now consists of a matrix of natural forests, managed forests, agricultural cropland, and urbanized plots. Expansion of domestic energy production efforts in the United States is one driver predicted to influence future land-use and land management practices across large spatial scales. Favorable growing conditions make the southeastern United States an ideal location...
