Data from: Exotic flower visitors exploit large floral trait spaces resulting in asymmetric resource partitioning with native visitors

Jonas Kuppler, Maren K. Höfers, Wolfgang Trutschnig, Arne C. Bathke, Jesse A. Eiben, Curtis C. Daehler & Robert R. Junker
1.Exotic species often cause severe alterations in native communities due to their ability to rapidly and efficiently utilize a broad spectrum of resources. In flower-visitor interactions, the breadth of resource use by native and exotic animals as well as the partitioning of resources among them is often estimated based on the number of (shared) plant species used as resources. However, whether a flower visitor is able to exploit plant resources has been shown to be...

Data from: Marine biodiversity at the end of the world: Cape Horn and Diego Ramírez islands

Alan M. Friedlander, Enric Ballesteros, Tom W. Bell, Jonatha Giddens, Brad Henning, Mathias Hüne, Alex Muñoz, Pelayo Salinas-De-León & Enric Sala
The vast and complex coast of the Magellan Region of extreme southern Chile possesses a diversity of habitats including fjords, deep channels, and extensive kelp forests, with a unique mix of temperate and sub-Antarctic species. The Cape Horn and Diego Ramírez archipelagos are the most southerly locations in the Americas, with the southernmost kelp forests, and some of the least explored places on earth. The giant kelp Macrocystis pyrifera plays a key role in structuring...

Data from: Linking genotype to phenotype in a changing ocean: inferring the genomic architecture of a blue mussel stress response with genome-wide association

Sarah E. Kingston, Pieter Martino, Marko Melendy, Floyd A. Reed & David B. Carlon
A key component to understanding the evolutionary response to a changing climate is linking underlying genetic variation to phenotypic variation in stress response. Here we use a genome-wide association approach (GWAS) to understand the genetic architecture of calcification rates under simulated climate stress. We take advantage of the genomic gradient across the blue mussel hybrid zone (Mytilus edulis and Mytilus trossulus) in the Gulf of Maine (GOM) to link genetic variation with variance in calcification...

Data from: When environmental factors become stressors: interactive effects of vermetid gastropods and sedimentation on corals

Julie Zill, Michael A. Gil, Craig W. Osenberg & Julie A. Zill
Environmental stressors often interact, but most studies of multiple stressors have focused on combinations of abiotic stressors. Here we examined the potential interaction between a biotic stressor, the vermetid snail Ceraesignum maximum, and an abiotic stressor, high sedimentation, on the growth of reef-building corals. In a field experiment, we subjected juvenile massive Porites corals to four treatments: (i) neither stressor, (ii) sedimentation, (iii) vermetids or (iv) both stressors. Unexpectedly, we found no effect of either...

Data from: Impact of model violations on the inference of species boundaries under the multispecies coalescent

Anthony J. Barley, Jeremy M. Brown & Robert C. Thomson
The use of genetic data for identifying species-level lineages across the tree of life has received increasing attention in the field of systematics over the past decade. The multispecies coalescent model provides a framework for understanding the process of lineage divergence, and has become widely adopted for delimiting species. However, because these studies lack an explicit assessment of model fit, in many cases, the accuracy of the inferred species boundaries are unknown. This is concerning...

Data from: Epidemic and endemic pathogen dynamics correspond to distinct host population microbiomes at a landscape scale

Andrea J. Jani, Roland A. Knapp & Cheryl J. Briggs
Infectious diseases have serious impacts on human and wildlife populations, but the effects of a disease can vary, even among individuals or populations of the same host species. Identifying the reasons for this variation is key to understanding disease dynamics and mitigating infectious disease impacts, but disentangling cause and correlation during natural outbreaks is extremely challenging. This study aims to understand associations between symbiotic bacterial communities and an infectious disease, and examines multiple host populations...

Data from: The importance of standardization for biodiversity comparisons: a case study using Autonomous Reef Monitoring Structures (ARMS) and metabarcoding to measure cryptic diversity on Mo'orea coral reefs, French Polynesia

Emma Ransome, Jonathan B. Geller, Molly Timmers, Matthieu Leray, Angka Mahardini, Andrianus Sembiring, Allen G. Collins & Christopher P. Meyer
The advancement of metabarcoding techniques, declining costs of high-throughput sequencing and development of systematic sampling devices, such as autonomous reef monitoring structures (ARMS), have provided the means to gather a vast amount of diversity data from cryptic marine communities. However, such increased capability could also lead to analytical challenges if the methods used to examine these communities across local and global scales are not standardized. Here we compare and assess the underlying biases of four...

Data from: Recurrent fruit harvesting reduces seedling density but increases the frequency of clonal reproduction in a tropical tree

Orou G. Gaoue, Choukouratou Gado, Armand K. Natta & M’Mouyohoun Kouagou
Studies on the ecological impacts of non-timber forest products (NTFP) harvest reveal that plants are often more resilient to fruit and seed harvest than to bark and root harvest. Several studies indicate that sustainable fruit harvesting limits can be set very high (>80% fruit harvesting intensity). For species with clonal and sexual reproduction, understanding how fruit harvest affects clonal reproduction can shed light on the genetic risks and sustainability of NTFP harvest. We studied 18...

Data from: Contrasts in the marine ecosystem of two Macaronesian islands: a comparison between the remote Selvagens Reserve and Madeira Island

Alan M. Friedlander, Enric Ballesteros, Sabrina Clemente, Emanuel J. Gonçalves, Andrew Estep, Paul Rose & Enric Sala
The islands of Madeira and Selvagens are less than 300 km apart but offer a clear contrast between a densely populated and highly developed island (Madeira), and a largely uninhabited and remote archipelago (Selvagens) within Macaronesia in the eastern Atlantic. The Madeira Archipelago has ~260,000 inhabitants and receives over six million visitor days annually. The Selvagens Islands Reserve is one of the oldest nature reserves in Portugal and comprises two islands and several islets, including...

Data from: Spatial separation without territoriality in shark communities

Yannis P. Papastamatiou, Thomas W. Bodey, Alan M. Friedlander, Christopher G. Lowe, Darcy Bradley, Kevin Weng, Victoria Priestley & Jennifer E. Caselle
Spatial separation within predator communities can arise via territoriality but also from competitive interactions between and within species. However, linking competitive interactions to predator distribution patterns is difficult and theoretical models predict different habitat selection patterns dependent on habitat quality and how competition manifests itself. While models generally consider competitors to be either equal in ability, or for one phenotype to have a fixed advantage over the other, few studies consider that an animal may...

Data from: Vertical gradients in species richness and community composition across the twilight zone in the North Pacific Subtropical Gyre

Stephanie A. Sommer, Lauren Van Woudenberg, Petra H. Lenz, Georgina Cepeda & Erica Goetze
Although metazoan animals in the mesopelagic zone play critical roles in deep pelagic food webs and in the attenuation of carbon in midwaters, the diversity of these assemblages is not fully known. A metabarcoding survey of mesozooplankton diversity across the epipelagic, mesopelagic and upper bathypelagic zones (0-1500m) in the North Pacific Subtropical Gyre revealed far higher estimates of species richness than expected given prior morphology-based studies in the region (4,024 OTUs, 10-fold increase), despite conservative...

Data from: Elevated pCO2 affects tissue biomass composition, but not calcification, in a reef coral under two light regimes

Christopher B. Wall, Robert A. B. Mason, William R. Ellis, Ross Cunning & Ruth D. Gates
Ocean acidification (OA) is predicted to reduce reef coral calcification rates and threaten the long-term growth of coral reefs under climate change. Reduced coral growth at elevated pCO2 may be buffered by sufficiently high irradiances; however, the interactive effects of OA and irradiance on other fundamental aspects of coral physiology, such as the composition and energetics of coral biomass, remain largely unexplored. This study tested the effects of two light treatments (7.5 versus 15.7 mol...

Data from: Marine subsidies change short-term foraging activity and habitat utilization of terrestrial lizards

Heather V. Kenny, Amber N. Wright, Jonah Piovia-Scott, Louie Yang, David A. Spiller, Thomas W. Schoener & Louie H. Yang
Resource pulses are brief periods of unusually high resource abundance. While population and community responses to resource pulses have been relatively well-studied, how individual consumers respond to resource pulses has received less attention. Local consumers are the first to respond to a resource pulse, and the form and timing of individual responses may influence how the effects of the pulse are transmitted throughout the community. Previous studies in Bahamian food webs have shown that detritivores...

Data from: Ecological dispersal barrier across the equatorial Atlantic in a migratory planktonic copepod

Erica Goetze, Patricia T. Hüdepohl, Chantel Chang, Lauren Van Woudenberg, Matthew Iacchei & Katja T.C.A. Peijnenburg
Resolving the large-scale genetic structure of plankton populations is important to understanding their responses to climate change. However, few studies have reported on the presence and geographic extent of genetically distinct populations of marine zooplankton at ocean-basin scales. Using mitochondrial sequence data (mtCOI, 718 animals) from 18 sites across a basin-scale Atlantic transect (39 N–40 S), we show that populations of the dominant migratory copepod, Pleuromamma xiphias, are genetically subdivided across subtropical and tropical waters...

Data from: Cross-platform compatibility of de novo-aligned SNPs in a non-model butterfly genus

Erin O. Campbell, Corey S. Davis, Julian R. Dupuis, Kevin Muirhead, Felix A.H. Sperling & Felix A. H. Sperling
High-throughput sequencing methods for genotyping genome-wide markers are being rapidly adopted for phylogenetics of non-model organisms in conservation and biodiversity studies. However, the reproducibility of SNP genotyping and degree of marker overlap or compatibility between datasets from different methodologies have not been tested in non-model systems. Using double-digest restriction site associated DNA sequencing, we sequenced a common set of 22 specimens from the butterfly genus Speyeria on two different Illumina platforms, using two variations of...
