Data from: Going with the flow: hydrodynamic cues trigger directed escapes from a stalking predator

Lillian J. Tuttle, H. Eve Robinson, Daisuke Takagi, J. Rudi Strickler, Petra H. Lenz & Daniel K. Hartline
In the coevolution of predator and prey, different and less well understood rules for threat-assessment apply to freely suspended organisms than to substrate-dwelling ones. Particularly vulnerable are small prey carried with the bulk movement of a surrounding fluid and thus deprived of sensory information within the bow waves of approaching predators. Some planktonic prey have solved this apparent problem, however. We quantified cues generated by the slow approach of larval clownfish (Amphiprion ocellaris) that triggered...

Data from: Adaptive responses and local stressor mitigation drive coral resilience in warmer, more acidic oceans

Christopher P. Jury & Robert J. Toonen
Coral reefs have great biological and socioeconomic value, but are threatened by ocean acidification, climate change, and local human impacts. The capacity for corals to adapt or acclimatise to novel environmental conditions is unknown but fundamental to projected reef futures. The coral reefs of Kāne‘ohe Bay, Hawai‘i were devastated by anthropogenic insults from the 1930s-1970s. These reefs experience naturally reduced pH and elevated temperature relative to many other Hawaiian reefs which are not expected to...

Fungal infection alters the selection, dispersal, and drift processes structuring the amphibian skin microbiome

Mark Q Wilber, Andrea J Jani, Joseph R Mihaljevic & Cheryl J Briggs
Symbiotic microbial communities are important for host health, but the processes shaping these communities are poorly understood. Understanding how community assembly processes jointly affect microbial community composition is limited because inflexible community models rely on rejecting dispersal and drift before considering selection. We developed a flexible community assembly model based on neutral theory to ask: How do dispersal, drift, and selection concurrently affect the microbiome across environmental gradients? We applied this approach to examine how...

Data from: Developmental constraints and resource environment shape early emergence and investment in spines in saplings

Mohammed Armani, Tristan Charles-Dominique, Kasey E. Barton & Kyle W. Tomlinson
Abstract Background and Aims Herbivory by large mammals imposes a critical recruitment bottleneck on plants in many systems. Spines defend plants against large herbivores and how early they emerge in saplings may be one of the strongest predictors of sapling survival in herbivore-rich environments. Yet little effort has been directed at understanding the variability in spine emergence across saplings. Methods We present a multi-species study examining whether and how sapling size,spine type and species’ environmental...

Data from: The molecular biogeography of the Indo-Pacific: testing hypotheses with multispecies genetic patterns

Magnuson, John B. Horne, Marc Kochzius, Harilaos A. Lessios, Shang Yin Vanson Liu, William B. Ludt, Hawis Madduppa, John M. Pandolfi, Robert R. Toonen, Contributing Members Of Diversity Of The Indo-Pacific Network & Michelle R. Gaither
Aim: To test hypothesized biogeographic partitions of the tropical Indo-Pacific Ocean with phylogeographic data from 56 taxa, and to evaluate the strength and nature of barriers emerging from this test. Location: The Indo-Pacific Ocean. Time Period: Pliocene through the Holocene. Major Taxa Studied: 56 marine species. Methods: We tested eight biogeographic hypotheses for partitioning of the Indo-Pacific using a novel modification to analysis of molecular variance. Putative barriers to gene flow emerging from this analysis...

Data from: Interaction among ploidy, breeding system, and lineage diversification

Rosana Zenil-Ferguson, J. Gordon Burleigh, William A. Freyman, Boris Igic, Itay Mayrose & Emma E. Goldberg
If particular traits consistently affect rates of speciation and extinction, broad macroevolutionary patterns can be interpreted as consequences of selection at high levels of the biological hierarchy. Identifying traits associated with diversification rates is difficult because of the wide variety of characters under consideration and the statistical challenges of testing for associations from comparative phylogenetic data. Ploidy (diploid vs. polyploid states) and breeding system (self-incompatible vs. self-compatible states) are both thought to be drivers of...

Diel temperature and pH variability scale with depth across diverse coral reef habitats

Tyler Cyronak, Yui Takeshita, Travis A. Courtney, Eric H. DeCarlo, Bradley D. Eyre, David I. Kline, Todd Martz, Heather Page, Nichole N. Price, Jennifer Smith, Laura Stoltenberg, Martin Tresguerres & Andreas J. Andersson
Coral reefs are facing intensifying stressors, largely due to global increases in seawater temperature and decreases in pH. However, there is extensive environmental variability within coral reef ecosystems which can impact how organisms respond to global trends. We deployed spatial arrays of autonomous sensors across distinct shallow coral reef habitats to determine patterns of spatiotemporal variability in seawater physicochemical parameters. Temperature and pH were positively correlated over the course of a day due to solar...

Data from: Is MHC diversity a better marker for conservation than neutral genetic diversity? a case study of two contrasting dolphin populations

Oliver Manlik, Michael Krutzen, Anna M. Kopps, Janet Mann, Lars Bejder, Simon J. Allen, Celine Frere, Richard C. Connor & William B. Sherwin
Genetic diversity is essential for populations to adapt to changing environments. Measures of genetic diversity are often based on selectively neutral markers, such as microsatellites. Genetic diversity to guide conservation management, however, is better reflected by adaptive markers, including genes of the major histocompatibility complex (MHC). Our aim was to assess MHC and neutral genetic diversity in two contrasting bottlenose dolphin (Tursiops aduncus) populations in Western Australia—one apparently viable population with high reproductive output (Shark...

Data from: Plant competition as a mechanism of invasion on islands: revisiting the conclusions of Kuebbing and Nuñez (2016)

Kasey E. Barton & Amanda Wong.
Identifying the mechanisms underlying invasive plant establishment and native plant decline remains a central goal in ecology, particularly for biodiversity hotspots such as islands. We re-analyzed a previously published meta-dataset to test the prediction that neighbor effects are stronger on islands vs. continents because island plants are weaker competitors. Although we detected marginally stronger neighbor effects on islands than continents, this was due, at least in part, to stronger competition among native species. An absence...

Data from: Picoplankton carbon biomass assessments and distribution of Prochlorococcus ecotypes linked to Loop Current Eddies during summer in the southern Gulf of Mexico

L. Linacre, R. Durazo, V. F. Camacho‐Ibar, K.E. Selph, J.R. Lara‐Lara, U. Mirabal‐Gómez, C. Bazán‐Guzmán, A. Lago‐Lestón, E.M. Fernández‐Martín & K. Sidón‐Ceseña
Assessments of picoplankton carbon biomass in the pelagic ecosystem over the deep region of the southern Gulf of Mexico were conducted during three consecutive summer cruises. Notably, the relationship between carbon distribution of Prochlorococcus (PRO) and Loop Current (LC) dynamics was evaluated. Seawater samples were collected from the euphotic zone (~150 m) for estimating the abundance of the picoplankton populations using flow cytometry analyses. Carbon biomass estimates were based on cell abundance and variable conversion...

Data from: The advantages of going large: genome‐wide SNPs clarify the complex population history and systematics of the threatened western pond turtle

Phillip Q. Spinks, Robert C. Thomson & H. Bradley Shaffer
As the field of phylogeography has matured, it has become clear that analyses of one or a few genes may reveal more about the history of those genes than the populations and species that are the targets of study. To alleviate these concerns, the discipline has moved towards larger analyses of more individuals and more genes, although little attention has been paid to the qualitative or quantitative gains that such increases in scale and scope...

Deficits in functional trait diversity following recovery on coral reefs

Mike McWilliam
The disturbance regimes of ecosystems are changing, and prospects for continued recovery remain unclear. New assemblages with altered species composition may be functionally deficient. Alternatively, key functional traits may be sustained by species that replace those in decline (response diversity). Here, we quantify the recovery and response diversity of coral assemblages using case studies of disturbance in three locations. Despite return trajectories of coral cover, the original assemblages with diverse functional attributes failed to recover...
