Reproductive skew in multimale groups may be determined by the need for alpha males to offer reproductive opportunities as staying incentives to subordinate males (concessions), by the relative fighting ability of the alpha male (tug-of-war) or by how easily females can be monopolized (priority-of-access). These models have rarely been investigated in species with exceptionally long male tenures, such as white-faced capuchins, where female mate choice for novel unrelated males may be important in shaping reproductive...

Land-use change occurs nowhere more rapidly than in the tropics, where the imbalance between deforestation and forest regrowth has large consequences for the global carbon cycle1. However, considerable uncertainty remains about the rate of biomass recovery in secondary forests, and how these rates are influenced by climate, landscape, and prior land use2, 3, 4. Here we analyse aboveground biomass recovery during secondary succession in 45 forest sites and about 1,500 forest plots covering the major...

Data from: Song evolution, speciation, and vocal learning in passerine birds

Nicholas A. Mason, Kevin J. Burns, Joseph A. Tobias, Santiago Claramunt, Nathalie Seddon & Elizabeth Perrault Derryberry
Phenotypic divergence can promote reproductive isolation and speciation, suggesting a possible link between rates of phenotypic evolution and the tempo of speciation at multiple evolutionary scales. To date, most macroevolutionary studies of diversification have focused on morphological traits, whereas behavioral traitsࣧincluding vocal signalsࣧare rarely considered. Thus, although behavioral traits often mediate mate choice and gene flow, we have a limited understanding of how behavioral evolution contributes to diversification. Furthermore, the developmental mode by which behavioral...

Data from: Calling in sick: impacts of fever on intra-urban human mobility

T. Alex Perkins, Valerie A. Paz-Soldan, Steven T. Stoddard, Amy C. Morrison, Brett M. Forshey, Kanya C. Long, Eric S. Halsey, Tadeusz J. Kochel, John P. Elder, Uriel Kitron, Thomas W. Scott & Gonzalo M. Vazquez-Prokopec
Pathogens inflict a wide variety of disease manifestations on their hosts, yet the impacts of disease on the behaviour of infected hosts are rarely studied empirically and are seldom accounted for in mathematical models of transmission dynamics. We explored the potential impacts of one of the most common disease manifestations, fever, on a key determinant of pathogen transmission, host mobility, in residents of the Amazonian city of Iquitos, Peru. We did so by comparing two...

Data from: Poison frog color morphs express assortative mate preferences in allopatry but not sympatry

Yusan Yang, Corinne L. Richards-Zawacki, Anisha Devar & Matthew B. Dugas
The concurrent divergence of mating traits and preferences is necessary for the evolution of reproductive isolation via sexual selection, and such coevolution has been demonstrated in diverse lineages. However, the extent to which assortative mate preferences are sufficient to drive reproductive isolation in nature is less clear. Natural contact zones between lineages divergent in traits and preferences provide exceptional opportunities for testing the predicted evolutionary consequences of such divergence. The strawberry poison frog (Oophaga pumilio)...

Data from: Nectar robbing impacts pollinator behavior but not plant reproduction

Jenny A. Hazlehurst & Jordan O. Karubian
Trait-mediated indirect effects (TMIEs) refer to interactions in which the effect of one species on another is mediated by the behavior of a third species. A mechanistic approach that identifies the direction and impact of TMIEs can shed light on why different net outcomes are observed in the same general phenomena across systems. Nectar robbing has variable net effects through TMIEs on animal-pollinated plants across systems, but the mechanistic steps underlying this range of outcomes...

Data from: The response of migratory populations to phenological change: a Migratory Flow Network modelling approach

Caz M. Taylor, Andrew J. Laughlin & Richard J. Hall
1. Declines in migratory species have been linked to anthropogenic climate change through phenological mismatch, which arises due to asynchronies between the timing of life-history events (such as migration) and the phenology of available resources. Long-distance migratory species may be particularly vulnerable to phenological change in their breeding ranges, since the timing of migration departure is based on environmental cues at distant non-breeding sites. 2. Migrants may, however, be able to adjust migration speed en...

Data from: Rapid movement and instability of an invasive hybrid swarm

Gregory J. Glotzbecker, David M. Walters & Michael J. Blum
Unstable hybrid swarms that arise following the introduction of non-native species can overwhelm native congeners, yet the stability of invasive hybrid swarms has not been well documented over time. Here we examine genetic variation and clinal stability across a recently formed hybrid swarm involving native blacktail shiner (Cyprinella venusta) and non-native red shiner (C. lutrensis) in the Upper Coosa River basin, which is widely considered to be a global hotspot of aquatic biodiversity. Examination of...

Data from: The relative response of songbirds to shifts in song amplitude and song minimum frequency

David A. Luther, Ray Danner, Julie Danner, Katherine Gentry & Elizabeth P. Derryberry
Anthropogenic noise presents a problem for acoustic communication in animal taxa around the world. Many animals respond by modifying their acoustic signals, sometimes along multiple axes, such as song structure, redundancy, or amplitude. To date, no study has assayed the relative response of animals to multiple axes of signal variation, such as song structure and song amplitude, associated with anthropogenic noise levels. To investigate the impact of multiple potential adaptations to anthropogenic noise on targeted...

Data from: Geographic and host-mediated population genetic structure in a cestode parasite of the three-spined stickleback

Hannah M. Strobel, Fernando Alda, Charlotte Grace Sprehn, Michael J. Blum & David C. Heins
Comparative studies of genetic diversity and population structure can shed light on the ecological and evolutionary factors that influence host–parasite interactions. Here we examined whether geography, time and genetic variation in Alaskan three-spined stickleback (Gasterosteus aculeatus Linneaus) hosts shape the population genetic structure of the diphyllobothridean cestode parasite Schistocephalus solidus (Müller, 1776). Host lineages and haplotypes were identified by sequencing the mitochondrial cytochrome b gene, and host population structure was assessed by Bayesian clustering analysis...

Data from: Colonization and demographic expansion of freshwater fauna across the Hawaiian Archipelago

Fernando Alda, Roderick B. Gagne, Ryan P. Walter, J. Derek Hogan, Kristine N. Moody, Frida Zink, Peter B. McIntyre, James F. Gilliam & Michael J. Blum
It is widely accepted that insular terrestrial biodiversity progresses with island age because colonization and diversification proceed over time. Here we assess whether this principle extends to oceanic island streams. We examined range-wide mtDNA sequence variation in four stream-dwelling species across the Hawaiian archipelago to characterize the relationship between colonization and demographic expansion, and to determine whether either factor reflects island age. We found that colonization and demographic expansion are not related and that neither...

Data from: Teasing apart plant community responses to N enrichment: the roles of resource limitation, competition and soil microbes

Emily C. Farrer & Katharine N. Suding
Although ecologists have documented the effects of nitrogen enrichment on productivity, diversity and species composition, we know little about the relative importance of the mechanisms driving these effects. We propose that distinct aspects of environmental change associated with N enrichment (resource limitation, asymmetric competition, and interactions with soil microbes) drive different aspects of plant response. We test this in greenhouse mesocosms, experimentally manipulating each factor across three ecosystems: tallgrass prairie, alpine tundra and desert grassland....

Data from: Global population divergence and admixture of the brown rat (Rattus norvegicus)

Emily E. Puckett, Jane Park, Matthew Combs, Michael J. Blum, Juliet E. Bryant, Adalgisa Caccone, Federico Costa, Eva E. Deinum, Alexandra Esther, Chelsea G. Himsworth, Peter D. Keightley, Albert Ko, Ake Lundkvist, Lorraine M. McElhinney, Serge Morand, Judith Robins, James Russell, Tanja M. Strand, Olga Suarez, Lisa Yon & Jason Munshi-South
Native to China and Mongolia, the brown rat (Rattus norvegicus) now enjoys a worldwide distribution. While black rats and the house mouse tracked the regional development of human agricultural settlements, brown rats did not appear in Europe until the 1500s, suggesting their range expansion was a response to relatively recent increases in global trade. We inferred the global phylogeography of brown rats using 32 k SNPs, and detected 13 evolutionary clusters within five expansion routes....

Data from: Behavioral response to song and genetic divergence in two subspecies of white-crowned sparrows (Zonotrichia leucophrys)

Sara E. Lipshutz, Isaac A. Overcast, Michael J. Hickerson, Robb T. Brumfield & Elizabeth P. Derryberry
Divergence in sexual signals may drive reproductive isolation between lineages, but behavioral barriers can weaken in contact zones. Here, we investigate the role of song as a behavioral and genetic barrier in a contact zone between two subspecies of white-crowned sparrows (Zonotrichia leucophrys). We employed a reduced genomic dataset to assess population structure and infer the history underlying divergence, gene flow and hybridization. We also measured divergence in song and tested behavioral responses to song...
