Data from: A morphometric analysis of vegetation patterns in dryland ecosystems

Luke Mander, Stefan C. Dekker, Mao Li, Washington Mio, Surangi W. Punyasena & Timothy M. Lenton
Vegetation in dryland ecosystems often forms remarkable spatial patterns. These range from regular bands of vegetation alternating with bare ground, to vegetated spots and labyrinths, to regular gaps of bare ground within an otherwise continuous expanse of vegetation. It has been suggested that spotted vegetation patterns could indicate that collapse into a bare ground state is imminent, and the morphology of spatial vegetation patterns, therefore, represents a potentially valuable source of information on the proximity...

Data from: Male and female contributions to behavioral isolation in darters as a function of genetic distance and color distance

Rachel L. Moran, Muchu Zhou, Julian M. Catchen & Rebecca C. Fuller
Determining which reproductive isolating barriers arise first between geographically isolated lineages is critical to understanding allopatric speciation. We examined behavioral isolation among four recently diverged allopatric species in the orangethroat darter clade (Etheostoma: Ceasia). We also examined behavioral isolation between each Ceasia species and the sympatric rainbow darter Etheostoma caeruleum. We asked (1) is behavioral isolation present between allopatric Ceasia species, and how does this compare to behavioral isolation with E. caeruleum, (2) does male...

Data from: Hydrology controls recruitment of two invasive cyprinids: bigheaded carp reproduction in a navigable large river

Daniel K. Gibson-Reinemer, Levi E. Solomon, Richard M. Pendleton, John H. Chick & Andrew F. Casper
In the Mississippi River Basin of North America, invasive bigheaded carp (silver carp Hypophthalmichthys molitrix and bighead carp H. nobilis, also referred to as Asian carp) have spread rapidly over the past several decades. In the Illinois River, an important tributary of the Upper Mississippi River, reproduction appears to be sporadic and frequently unsuccessful, yet bigheaded carp densities in this river are among the highest recorded on the continent. Understanding the causative factors behind erratic...

Data from: Trpc2 Pseudogenization dynamics in bats reveal ancestral vomeronasal signaling, then pervasive loss

Laurel R. Yohe, Ramatu Abubakar, Christina Giordano, Elizabeth Dumont, Karen Sears, Stephen J. Rossiter, Liliana M. Davalos & Karen E. Sears
Comparative methods are often used to infer loss or gain of complex phenotypes, but few studies take advantage of genes tightly linked with complex traits to test for shifts in the strength of selection. In mammals vomerolfaction detects chemical cues mediating many social and reproductive behaviors and is highly conserved, but all bats exhibit degraded vomeronasal structures with the exception of two families (Phyllostomidae and Miniopteridae). These families either regained vomerolfaction after ancestral loss, or...

Data from: The critical role of local refugia in postglacial colonization of Chinese pine: joint inferences from DNA analyses, pollen records, and species distribution modeling

Qian Hao, Guillaume De Lafontaine, Dongshu Guo, Hongya Gu, Feng Sheng Hu, Yue Han, Zhaoliang Song & Hongyan Liu
The importance of long-distance migration from low to high latitudes relative to local spread from northern refugia after the Last Glacial Maximum (LGM) remains a focus of debate for many temperate tree species. We assessed the dynamics of Chinese pine (Pinus tabulaeformis), a widespread species endemic to northern China, since the LGM by integrating cytoplasmic DNA data, mapped pollen records and ecological niche modeling. Genetic variation among 544 individuals from 50 populations spanning the entire...

Data from: Common evolutionary trends underlie the four-bar linkage systems of sunfish and mantis shrimp

Yinan Hu, Nathan Nelson-Maney, Philip S.L. Anderson & Philip S. L. Anderson
Comparative biomechanics offers an opportunity to explore the evolution of disparate biological systems that share common underlying mechanics. Four-bar linkage modelling has been applied to various biological systems such as fish jaws and crustacean appendages to explore the relationship between biomechanics and evolutionary diversification. Mechanical sensitivity states that the functional output of a mechanical system will show differential sensitivity to changes in specific morphological components. We document similar patterns of mechanical sensitivity in two disparate...

Data from: Eggshells as hosts of bacterial communities: an experimental test of the antimicrobial egg coloration hypothesis

Donald C. Dearborn, Symmantha M. Page, Miri Dainson, Mark E. Hauber & Daniel Hanley
Oviparous animals have evolved multiple defenses to prevent microbes from penetrating their eggs and causing embryo mortality. In birds, egg constituents such as lysozyme and antibodies defend against microbial infestation, but eggshell pigments might also impact survival of bacteria. If so, microbes could exert an important selective pressure on the evolution of eggshell coloration. In a previous lab experiment, eggshell protoporphyrin caused drastic mortality in cultures of Gram positive, but not Gram negative, bacteria when...

Data from: The relationship between male sexual signals, cognitive performance, and mating success in stickleback fish

Ross Minter, Jason Keagy & Robin M. Tinghitella
Cognitive ability varies dramatically among individuals, yet the manner in which this variation correlates with reproduction has rarely been investigated. Here, we ask 1) do male sexual signals reflect their cognitive ability, and 2) is cognitive ability associated with male mating success? Specifically, we presented threespine sticklebacks (Gasterosteus aculeatus) with a detour-reaching task to assess initial inhibitory control. Fish that performed better were those who solved the detour-reaching task, solved it faster, and required fewer...

Data from: Pre-dispersal seed predators and fungi differ in their effect on Luehea seemannii capsule development, seed germination and dormancy across two Panamanian forests

Pimonrat Tiansawat, Noelle G. Beckman & James W. Dalling
Pre-dispersal seed predation can greatly reduce crop size affecting recruitment success. Additionally, non-fatal damage by seed predators may allow infection by fungi responsible for post-dispersal seed losses. The objectives of this study were (1) to quantify pre-dispersal seed predation and fungal infection in a Neotropical tree species, Luehea seemannii, that produces dehiscent fruits and wind-dispersed seeds, and (2) to link pre-dispersal effects on seed quality to seed survival in the soil. To examine how seed...

Data from: Genetic rescue, the greater prairie chicken and the problem of conservation reliance in the Anthropocene

Steven M. Mussmann, Marlis R. Douglas, Whitney J.B. Anthonysamy, Mark A. Davis, Scott A. Simpson, Wade Louis, Michael E. Douglas & W. J. B. Anthonysamy
A central question in conservation is how best to manage biodiversity, despite human domination of global processes (= Anthropocene). Common responses (i.e. translocations, genetic rescue) forestall potential extirpations, yet have an uncertain duration. A textbook example is the greater prairie chicken (GRPC: Tympanuchus cupido pinnatus), where translocations (1992–1998) seemingly rescued genetically depauperate Illinois populations. We re-evaluated this situation after two decades by genotyping 21 microsatellite loci from 1831 shed feathers across six leks in two...

Data from: Macroevolutionary synthesis of flowering plant sexual systems

Emma E. Goldberg, Sarah P. Otto, Jana C. Vamosi, Itay Mayrose, Niv Sabath, Ray Ming & Tia-Lynn Ashman
Sexual system is a key determinant of genetic variation and reproductive success, affecting evolution within populations and within clades. Much research in plants has focused on evolutionary transitions away from the most common state of hermaphroditism and toward the rare state of dioecy (separate sexes). Rather than transitions predominantly toward greater sexual differentiation, however, evolution may proceed in the direction of lesser sexual differentiation. We analyzed the macroevolutionary dynamics of sexual system in angiosperm genera...

Data from: Geographically structured genetic variation in the Medicago lupulina – Ensifer mutualism

Tia L. Harrison, Corlett Wolfe Wood, Katy D. Heath & John R. Stinchcombe
Gene flow between genetically differentiated populations can maintain variation in species interactions, especially when population structure is congruent between interacting species. However, large-scale empirical comparisons of the population structure of interacting species are rare, particularly in positive interspecific interactions (mutualisms). One agriculturally and ecologically important mutualism is the partnership between legume plants and rhizobia. Through characterizing and comparing the population genomic structure of the legume Medicago lupulina and two rhizobial species (Ensifer medicae and E....

Data from: Transcriptomic imprints of adaptation to fresh water: parallel evolution of osmoregulatory gene expression in the Alewife

Jonathan P. Velotta, Jill L. Wegrzyn, Samuel Ginzburg, Lin Kang, Sergiusz Czesny, Rachel J. O'Neill, Stephen D. McCormick, Pawel Michalak & Eric T. Schultz
Comparative approaches in physiological genomics offer an opportunity to understand the functional importance of genes involved in niche exploitation. We used populations of Alewife (Alosa pseudoharengus) to explore the transcriptional mechanisms that underlie adaptation to fresh water. Ancestrally anadromous Alewives have recently formed multiple, independently derived, landlocked populations, which exhibit reduced tolerance of saltwater and enhanced tolerance of fresh water. Using RNA-seq, we compared transcriptional responses of an anadromous Alewife population to two landlocked populations...

Data from: Ecological history of a long-lived conifer in a disjunct population

Erin M. Herring, Daniel G. Gavin, Solomon Z. Dobrowski, Matias Fernandez & Feng Sheng Hu
1. In northern Idaho (USA), more than 100 vascular plant species are disjunct <200 km from their main distribution along the Pacific Northwest coast. It remains unclear whether most species within this interior forest disjunction, including Tsuga mertensiana, survived the last glacial period in a north-Idaho refugium or whether these species colonized the region via long-distance dispersal during the Holocene. 2. Sediment cores were extracted from three mid- to high-elevation lakes within T. mertensiana dominated...

Data from: From the track to the ocean: using flow control to improve marine bio-logging tags for cetaceans

Giovani Fiore, Erik Anderson, C. Spencer Garborg, Mark Murray, Mark Johnson, Michael J. Moore, Laurens Howle & K. Alex Shorter
Bio-logging tags are an important tool for the study of cetaceans, but superficial tags inevitably increase hydrodynamic loading. Substantial forces can be generated by tags on fast-swimming animals, potentially affecting behavior and energetics or promoting early tag removal. Streamlined forms have been used to reduce loading, but these designs can accelerate flow over the top of the tag. This non-axisymmetric flow results in large lift forces (normal to the animal) that become the dominant force...

Data from: Parenting behaviour is highly heritable in male stickleback

Alison M. Bell, Rebecca Trapp & Jason Keagy
Parental care is critical for fitness, yet little is known about its genetic basis. Here, we estimate the heritability of parenting behaviour in a species famous for its diversity and its behavioural repertoire: three-spined stickleback (Gasterosteus aculeatus). Male threespined stickleback are the sole providers of paternal care that is necessary for offspring survival, therefore this system offers the opportunity to study the inheritance of parental behavior when selection is primarily acting on males. Fanning behaviour...
