Data from: Coexistence and origin of trophic ecotypes of pygmy whitefish, Prosopium coulterii, in southwestern Alaskan lake

Tom P. Quinn, Conrad P. Gowell & Eric B. Taylor
Ecologically, morphologically, and genetically distinct populations within single taxa often co-exist in postglacial lakes and have provided important model systems with which to investigate ecological and evolutionary processes such as niche partitioning and ecological speciation. Within the Salmonidae, these species complexes have been well studied, particularly within the Coregonus clupeaformis-C. laveratus (lake and European whitefish, respectively) group, but the phenomenon has been less well documented in the other whitefish genera, Prosopium and Stenodus. Here, we...

Theresa Burg, Marie Prill, Katharine Studholme, Alice Domalik, Strahan Tucker, Catherine Jardine, Mark Maftei, Kenneth Wright, Jesse Beck, Russell Bradley, Ryan Carle, Thomas Good, Scott Hatch, Peter Hodum, Motohiro Ito, Scott Pearson, Nora Rojek, Leslie Slater, Yutaka Watanuki, Alexis Will, Aidan Bindoff, Glenn Crossin, Mark Drever & Mark Hipfner
We tested the hypothesis that segregation in wintering areas promotes population differentiation in a sentinel North Pacific seabird, the rhinoceros auklet (Cerorhinca monocerata). We collected tissue samples for genetic analyses on five breeding colonies in the western Pacific Ocean (Japan) and 13 in the eastern Pacific Ocean (California to Alaska), and deployed light-level geologgers on 12 eastern Pacific colonies to delineate wintering areas. Loggers were deployed previously on one colony in Japan. There was strong...

Data From: Active sinking particles: Flow and transport dynamics due to sessile suspension feeders on sinking aggregates

Rachel Pepper, Deepak Krishnamurthy & Manu Prakash
Sinking or sedimentation of biological aggregates plays a critical role in carbon sequestration in the ocean and in vertical material fluxes in waste-water treatment plants. In both these contexts, the sinking aggregates are “active,” since they are biological hot-spots and are densely colonized by microorganisms including bacteria and sessile protists, some of which generate feeding currents. However, the effect of these feeding currents on the sinking rates, trajectories, and mass transfer to these "active sinking...

Data from: Increased behavioural lateralization in parasitized coral reef fish

Dominique G. Roche, Sandra A. Binning, Laura E. Strong, Jaclyn N. Davies & Michael D. Jennions
Preferential use of one side of the body for cognitive or behavioural tasks (lateralization) is common in many animals, including humans. However, few studies have demonstrated whether lateralization is phenotypically plastic, and varies depending on the ecological context. We studied lateralization (measured as a turning preference) in the bridled monocle bream (Scolopsis bilineatus). This coral reef fish is commonly infected by a large, ectoparasitic isopod (Anilocra nemipteri) that attaches to the left or right side...

Plant-plant interactions change during succession on nurse logs in a northern temperate rainforest

Carrie L Woods, Katy Maleta & Kimmy Ortmann
Plant-plant interactions change through succession from facilitative to competitive. At early stages of succession, early-colonizing plants can increase the survival and reproductive output of other plants by ameliorating disturbance and stressful conditions. At later stages of succession, plant interactions are more competitive as plants put more energy towards growth and reproduction. In northern temperate rainforests, gap dynamics result in tree falls that facilitate tree regeneration (nurse logs) and bryophyte succession. How bryophyte-tree seedling interactions vary...

Data from: Predator-induced collapse of niche structure and coexistence on islands

Robert M. Pringle, Tyler R. Kartzinel, Todd M. Palmer, Timothy J. Thurman, Kena Fox-Dobbs, Charles C. Y. Xu, Matthew C. Hutchinson, Tyler C. Coverdale, Joshua H. Daskin, Dominic A. Evangelista, Kiyoko M. Gotanda, , Johanna E. Wegener, Jason J. Kolbe, Thomas W. Schoener, David A. Spiller, Jonathan B. Losos & Rowan D. H. Barrett
Biological invasions represent both a pressing environmental challenge and an opportunity to investigate fundamental ecological processes, such as the role of top predators in regulating species diversity and food-web structure. In whole-ecosystem manipulations of small Caribbean islands where brown anole lizards (Anolis sagrei) were the native top predator, we experimentally staged invasions by competitors (green anoles, A. smaragdinus) and/or novel top predators (curly-tailed lizards, Leiocephalus carinatus). We show that curly-tails destabilized coexistence of competing prey...

Data from: Putting vascular epiphytes on the traits map

Peter Hietz, Katrin Wagner, Flavio Nunes Ramos, Juliano Sarmento Cabral, Gerhard Zotz, Claudia Agudelo, Ana Maria Benavides, Manuel Cach Pérez, Catherine Cardelús, Nahelli Chilpa Galván, Lucas Costa, Rodolfo De Paula Oliveiras, Helena Einzmann, Rafael Farias, Valeria Guzmán Jacob, Michael Kessler, Catherine Kirby, Holger Kreft, Thorsten Krömer, Jamie Males, Samuel Monsalve Correa, Maria Moreno, Gunnar Petter, Casandra Reyes, Alfredo Saldaña … & Carrie Woods
Epiphyte trait data for the paper Hietz et al. 2021 Putting vascular epiphytes on the traits map. Journal of Ecology Plant functional traits impact the fitness and environmental niche of plants. Major plant functional types have been characterized by their trait spectrum, and the environmental and phylogenetic imprints on traits have advanced several ecological fields. Yet very few trait data on epiphytes, which represent almost 10% of vascular plants, are available. We collated >80,000 mostly...

Data from: Artificial selection on anther exsertion in wild radish, Raphanus raphanistrum

Jeffrey K. Conner, Cynthia J. Mills, Vanessa A. Koelling & Keith Karoly
To study the genetic architecture of anther exsertion, a trait under stabilizing selection in wild radish, artificial selection on anther exsertion was applied for 11 generations. Two replicate lines each of increased and decreased exsertion plus two randomly-mated controls were included. Full pedigree information is available from generation five. To estimate correlated responses to selection, 571 plants from all lines and matrilines were grown in the greenhouse and a number of floral, growth, and phenology...

Data from: Primary ecological succession in vascular epiphytes: the species accumulation model

Carrie L. Woods
Epiphytes are integral to tropical forests yet little is understood about how succession proceeds in these communities. As trees increase in size they create microhabitats for late-colonizing species in both small and large branches while maintaining small tree microhabitats for early colonizing species in the small and young branches. Thus, epiphyte succession may follow different models depending on the scale: at the scale of the entire tree, epiphytes may follow a species accumulation model where...

Data from: The effect of external flow on the feeding currents of sessile microorganisms

Rachel Pepper
Microscopic sessile suspension feeders live attached to surfaces and, by consuming bacteria-sized prey and by being consumed, they form an important part of aquatic ecosystems. Their environmental impact is mediated by their feeding rate, which depends on a self-generated feeding current. The feeding rate has been hypothesized to be limited by recirculating eddies that cause the organisms to feed from water that is depleted of food particles. However, those results considered organisms in still water,...

Cloacal microbiomes of sympatric and allopatric Sceloporus lizards vary with environment and host relatedness

Marie Bunker & Stacey Weiss
Animals and their microbiomes exert reciprocal influence; the host’s environment, physiology, and phylogeny can impact the composition of the microbiome, while the microbes present can affect host behavior, health, and fitness. While some microbiomes are highly malleable, specialized microbiomes that provide important functions can be more robust to environmental perturbations. Recent evidence suggests Sceloporus virgatus has one such specialized microbiome, which functions to protect eggs from fungal pathogens during incubation. Here, we examine the cloacal...

Whiptail lizards (Aspidoscelis exsanguis) recognize invertebrate prey via cuticular hydrocarbons

Jay Goldberg, Genevieve Pintel, Jake A Pruett & Stacey L Weiss
Cuticular hydrocarbons (CHCs) present on the surface of arthropods are important mediators of both intraspecific and interspecific interactions. They are known to be important chemical cues that help predatory arthropods locate prey, yet less is known about if and how vertebrate insectivores use these nearly ubiquitous chemical cues. We examined behavioral responses of insectivorous lizards (Aspidoscelis exsanguis) to the CHCs of three different species of arthropod prey (crickets, ants, and spiders). We presented cotton swabs...

Wildfire as a natural stressor and its effect on female phenotype and ornament development

Stacey Weiss & Robert Brower
Controlled low-intensity fires are commonly used in ecosystem management for both habitat restoration and wildfire management. Animals in those ecosystems may respond to fire by shifting energy allocation away from reproduction and growth, and toward maintenance. Stress-induced shifts in energy allocation may affect expression of condition-dependent sexual signals, which are sensitive to energetic and physiological trade-offs mediated by glucocorticoids. Here, we examine the effect of fire on ornament expression, corticosterone, and other phenotypic traits in...

Recovered microbiome of an oviparous lizard differs across gut and reproductive tissues, cloacal swabs, and feces

Marie Bunker, Mark Martin & Stacey Weiss
Microbial diversity and community function are related, and both can be highly specialized in different regions of the gut. The cloacal microbiome of Sceloporus virgatus lizards has low diversity, suggesting a specialized function, and is known to transfer antifungal microbes to eggshells during oviposition. We hypothesize that the cloacal microbiome is distinct from other parts of the digestive and reproductive systems. Here, we compare the microbiome of tissue samples from the cloaca, lower intestine, upper...

Data from: Predatory lizards perceive plant-derived volatile odorants

Jay K. Goldberg, Genevieve Pintel, Stacey L. Weiss & Emilia P. Martins
Many lizards are olfactory foragers and prey upon herbivorous arthropods, yet their responses to common herbivore‐associated plant volatiles remain unknown. As such, their role in mediating plant indirect defenses also remains largely obscured. In this paper, we use a cotton‐swab odor presentation assay to ask whether lizards respond to two arthropod‐associated plant‐derived volatile compounds: 2‐(E)‐hexenal and hexanoic acid. We studied the response of two lizard species, Sceloporus virgatusand Aspidoscelis exsanguis, because they differ substantially in...

Asymmetric song recognition does not influence gene flow in an emergent songbird hybrid zone

William Brooks & Peter Wimberger
Hybrid zones can be used to examine the mechanisms affecting reproductive isolation and speciation, like song. Song has equivocal support as a driver of speciation; we did not find song to cause reproductive isolation. We examined an emerging secondary contact zone between White-crowned Sparrow subspecies pugetensis and gambelii by measuring song variation, song recognition, plumage, morphology and mtDNA. Plumage and morphological characters provided evidence of hybridization in the contact zone, with some birds possessing plumage...

Data for: Wild microbiomes of striped plateau lizards vary with sex, body size, and reproductive season

Marie Bunker, A. Elizabeth Arnold & Stacey Weiss
Long-term natural studies are valuable for examining the effects of host demographics and environmental factors on animal microbiomes, and how those effects interact and shift over time. We examined how the cloacal microbiome of Sceloporus virgatus (the striped plateau lizard) varies under natural conditions in southeastern Arizona, USA, in a multi-year study. Cloacal swabs were collected from wild-caught lizards across their entire active season over three years. Analyses of 16S rRNA data generated on the...
