Elucidating mechanisms of invasion success: effects of parasite removal on growth and survival rates of invasive and native frogs

Elizabeth Roznik, Kerri Surbaugh, Natalia Cano & Jason Rohr
1. Identifying the mechanisms underlying biological invasions can inform the management of invasive species. The enemy release hypothesis (ERH) suggests that invasive species have a competitive advantage in their introduced range because they leave behind many of their predators and parasites from their native range, allowing them to shift resources from defenses to growth, reproduction, and dispersal. Many studies have demonstrated that invasive species have fewer parasites than their native counterparts, but few studies have...

This dataset contains oyster shell height measurements for prehistoric and modern oysters collected near Crystal River, Florida, USA. Oxygen and carbon stable isotope values for large prehistoric and modern oysters are also reported.

Data from: The most efficient metazoan swimmer creates a ‘virtual wall’ to enhance performance

Brad Gemmell
It has been well documented that animals (and machines) swimming or flying near a solid boundary get a boost in performance. This ground effect is often modeled as an interaction between a mirrored pair of vortices represented by a true vortex and an opposite sign ‘virtual vortex’ on the other side of the wall. However, most animals do not swim near solid surfaces and thus near body vortex-vortex interactions in open-water swimmers have been poorly...

Synoicum adareanum sampling underwater video March 2011 Palmer Station Antarctica

Bill Baker & Bill Dent
These 21 video clips document the sampling events for the tunicate Synoicum adareanum in support of a microbiome and biosynthetic gene cluster study. The sampling strategy involved seven sites, including Janus Island, Boneparte Point, Norsel Point, Delaca Island, Laggard Island, Killer Whale Rocks and Litchfield Island, which are all in the Palmer Archipeligo near the US Antarctic base at Palmer Station. At each site, at least three lobes of S. adareanum were collected, resulting in...

The impacts of body mass on immune cell concentrations in birds

Emily Cornelius Ruhs
Body mass affects many biological traits, but its impacts on immune defenses are fairly unknown. Recent research on mammals found that neutrophil concentrations disproportionately increased (scaled hypermetrically) with body mass, a result not predicted by any existing theory. Although the scaling relationship for mammals might predict how leukocyte concentrations scale with body mass in other vertebrates, vertebrate classes are distinct in many ways that might affect their current and historic interactions with parasites and hence...

Data from: The genetic architecture of plant defense tradeoffs in a common monkeyflower

Nicholas Kooyers, Benjamin Blackman, Abigail Donofrio & Liza Holeski
Determining how adaptive combinations of traits arose requires understanding the prevalence and scope of genetic constraints. Frequently observed phenotypic correlations between plant growth, defenses, and/or reproductive timing have led researchers to suggest that pleiotropy or strong genetic linkage between variants affecting independent traits is pervasive. Alternatively, these correlations could arise via independent mutations in different genes for each trait and extensive correlational selection. Here we evaluate these alternatives by conducting a QTL mapping experiment involving...

Differentially evolutionary pathways and their interactions in genes expressed in brain of human and macaque

Ju Wang, Yuequn Ma, Changying Cao, Mengwen Zhao, Xinhua Liu & Feng Cheng
As the key organ that separates human from other non-human primates, brain has continuously evolved to adapt to the changes of environments and climates. Although human shares most genetic, molecular and cellular features with primates like macaque, there are significant differences in the structure and function in brain of human and these species. Thus, exploring the differences between brains of human and non-human primates in the context of evolution will provide insights into the development,...

Data from: Can variation in seed removal patterns of Neotropical pioneer tree species be explained by local ant community composition?

Selina Ruzi, Paul-Camilo Zalamea, Daniel Roche, Rafael Achury, James Dalling & Andrew Suarez
Many plants depend on animals for seed dispersal, and ants commonly fill this role. We examined if heterogeneity in ant community composition among sites, between above- and below-ground foraging guilds, or between seasons predicts observed variation in seed removal rates for 12 nonmyrmecochorous Neotropical pioneer tree species on Barro Colorado Island, Panama. We also investigated if ants associated with removing seeds differed in specific morphological characters from the larger ant community. We observed ant-seed interactions...

Disentangling interactions among mercury, immunity, and infection in a Neotropical bat community

Daniel Becker, Kelly Speer, Jennifer Korstian, Dmitriy Volokhov, Hannah Droke, Alexis Brown, Catherene Baijnauth, Ticha Padgett-Stewart, Hugh Broders, Raina Plowright, Thomas Rainwater, Brock Fenton, Nancy Simmons & Matthew Chumchal
Contaminants such as mercury are pervasive and can have immunosuppressive effects on wildlife. Impaired immunity could be important for forecasting pathogen spillover risks, as many land-use changes that generate mercury contamination also bring wildlife into close contact with humans and domestic animals. However, the interactions among contaminants, immunity, and infection are difficult to study in natural systems, and empirical tests of possible directional relationships remain rare. We capitalized on extreme mercury variation in a diverse...

Spectral composition of light pollution affects melatonin suppression and West Nile virus infection resistance and mortality in the House Sparrow (Passer domesticus).

Meredith Kernbach, Vincent Cassone, Thomas Unnasch & Lynn Martin
Artificial light at night (ALAN) has become a pervasive anthropogenic stressor for both humans and wildlife. Although many negative impacts of ALAN on human health have been identified, the consequences for infectious disease dynamics are largely unexplored. With the increase in popularity of energy efficient light-emitting diodes (LEDs), the effects of spectral composition of ALAN have also come into question. Previous studies showed that exposure to low levels of incandescent ALAN extended the infectious period...

Data from: Estimating dispersal and evolutionary dynamics in diploporan blastozoans (Echinodermata) across the Great Ordovician Biodiversification Event

Adriane Lam, Sarah Sheffield & Nicholas Matzke
Echinoderms make up a substantial component of Ordovician marine invertebrates, yet their speciation and dispersal history as inferred within a rigorous phylogenetic and statistical framework is lacking. We use Biogeographic Stochastic Mapping (BSM; implemented in the R package BioGeoBEARS) to infer ancestral area relationships and the number and type of dispersal events through the Ordovician for diploporan blastozoans and related species. The BSM analysis was divided into three time slices to analyze how dispersal paths...

Evolution and development at the origin of a phylum

Bradley Deline, Jeffery Thompson, Nicholas Smith, Samuel Zamora, Imran Rahman, Sarah Sheffield, William Ausich, Thomas Kammer & Colin Sumrall
Quantifying morphological evolution is key to determining the patterns and processes underlying the origin of phyla. We constructed a hierarchical morphological character matrix to characterize the radiation and establishment of echinoderm body plans during the early Paleozoic. This showed that subphylum-level clades diverged gradually through the Cambrian, and the distinctiveness of the resulting body plans was amplified by the extinction of transitional forms and obscured by convergent evolution during the Ordovician. Higher-order characters that define...

Size-dependent predation and intraspecific inhibition of an estuarine snail feeding on oysters

Tim Pusack, J. Wilson White, Hanna G. Tillotson, David L. Kimbro & Christopher D. Stallings
Predator outbreaks have increased in the past two decades in many ecosystems and are predicted to become more common with climate change. During these outbreaks, predator densities increase rapidly, and can cause large reductions in prey populations or shifts in prey size structure. However, unexpected interactions may occur at high predator densities, necessitating a mechanistic understanding of how increased predator density affects predator-prey dynamics. In the northern Gulf of Mexico, outbreaks of southern oyster drill...

Data from: Trophic niche size and overlap decreases with increasing ecosystem productivity

Justin Lesser, William James, Rachel Wilson, Chris Stallings & James Nelson
The production and transfer of biomass through trophic relationships is a core ecosystem function. The movement of energy through the food web is mediated by organisms operating in their niche space. For generalists, the size of this niche space is inherently plastic and changes in response to available food sources. Therefore, this relationship between ecosystem productivity and niche size is an important determinant of ecosystem function. Competing theories about the nature of this relationship predict...
