CCAFS-CMIP5 Delta Method Downscaling database

Carlos Navarro-Racines, Jaime Tarapues-Montenegro, Edward Guevara, Andy Jarvis & Julián Ramírez-Villegas
We apply a downscaling method, called Delta Method, based on thin plate spline spatial interpolation of anomalies (deltas) of original GCM outputs. Anomalies are interpolated between GCM cell centroids and are then applied to a baseline climate given by a high resolution surface (i.e. WorldClim 1.4 , http://www.worldclim.org/). The process consists in the following steps: 1) Calculation of 30-year averages for present day simulations and 4 future periods; (2) calculation of anomalies as the absolute...

Data from: Integrated species distribution models: combining presence-background data and site-occupany data with imperfect detection

Vira Koshkina, Yan Wang, Ascelin Gordon, Robert M. Dorazio, Matt White & Lewi Stone
Two main sources of data for species distribution models (SDMs) are site-occupancy (SO) data from planned surveys, and presence-background (PB) data from opportunistic surveys and other sources. SO surveys give high quality data about presences and absences of the species in a particular area. However, due to their high cost, they often cover a smaller area relative to PB data, and are usually not representative of the geographic range of a species. In contrast, PB...

Data from: Marine soundscape shaped by fishing activity

Laura Coquereau, Julie Lossent, Jacques Grall & Laurent Chauvaud
Marine communities face anthropogenic pressures that degrade ecosystems. Because underwater soundscapes carry information about habitat quality, we explored whether destructive impacts of fishing could be evaluated via the soundscape. Maerl beds are recognized as biodiversity hotspots and they experience major worldwide degradation owing to fishing. We collected field acoustic recordings in maerl beds exposed to different fishing practices. We found that unfished maerl beds were threefold louder and exhibited sound frequencies more diversified than those...

Data from: Glutathione S-transferase protein expression in different life stages of zebrafish (Danio rerio)

Alena Tierbach, Ksenia J. Groh, René Schönenberger, Kristin Schirmer, Marc J.F. Suter & Suter, Marc J -F
Zebrafish is a widely used animal model in biomedical sciences and toxicology. Although evidence for the presence of phase I and phase II xenobiotic defense mechanisms in zebrafish exists on the transcriptional and enzyme activity level, little is known about the protein expression of xenobiotic metabolizing enzymes. Given the important role of glutathione S-transferases (GSTs) in phase II biotransformation, we analyzed cytosolic GST proteins in zebrafish early life stages and different organs of adult male...

Data from: Seagrass on the brink: decline of threatened seagrass Posidonia australis continues following protection

Suzanna M. Evans, Kingsley J. Griffin, Ray A. J. Blick, Alistair G. B. Poore & Adriana Verges
Seagrasses are in decline globally due to sustained pressure from coastal development, water quality declines and the ongoing threat from climate change. The result of this decline has been a loss of coastal productivity, a reduction in critical fisheries habitat and increased erosion. Attempts to slow this decline have included legislative protection of habitat and direct restoration efforts. Monitoring the success of these approaches requires tracking changes in the abundance of seagrasses, but such monitoring...

Data from: Using metagenomics to show the efficacy of forest restoration in the New Jersey Pine Barrens

William D. Eaton, Shadi Shokralla, Kathleen M. McGee & Mehrdad Hajibabaei
The Franklin Parker Preserve within the New Jersey Pine Barrens contains 5,000 acres of wetlands habitat, including old-growth Atlantic White Cedar (or AWC; Chamaecyparis thyoides) swamps, cranberry bogs, and former cranberry bogs undergoing restoration into AWC forests. This study showed that the C-use efficiency was greater in the old-growth AWC soils than in soils from 8-year old mid-stage restored AWC stands, which were greater than found in soil from 4-year old AWC stands—the latter two...

Data from: The seasonal climate niche predicts phenology and distribution of an ephemeral annual plant, Mollugo verticillata

Joe Hereford, Johanna Schmitt & David D. Ackerly
1.Many short-lived species complete their life cycles during brief seasonal windows of favorable environmental conditions. Such species may persist in the face of climate warming by migration to track their seasonal climate niche in space and/or by phenological shifts to track favorable conditions in time within the year. To describe the seasonal climate niche of the short-lived annual Mollugo verticillata in California, we used data from herbarium specimens and historic climate records to estimate environmental...

Data from: A modified GC-specific MAKER gene annotation method reveals improved and novel gene predictions of high and low GC content in Oryza sativa

Megan J. Bowman, Jane A. Pulman, Tiffany L. Liu & Kevin L. Childs
Background: Accurate structural annotation depends on well-trained gene prediction programs. Training data for gene prediction programs are often chosen randomly from a subset of high-quality genes that ideally represent the variation found within a genome. One aspect of gene variation is GC content, which differs across species and is bimodal in grass genomes. When gene prediction programs are trained on a subset of grass genes with random GC content, they are effectively being trained on...

Data from: Can collective memories shape fish distributions? A test, linking space-time occurrence models and population demographics

Jed I. Macdonald, Kai Logemann, Elias T. Krainski, Þorsteinn Sigurðsson, Colin M. Beale, Geir Huse, Solfrid S. Hjøllo & Guðrún Marteinsdóttir
Social learning can be fundamental to cohesive group living, and schooling fishes have proven ideal test subjects for recent work in this field. For many species, both demographic factors, and inter- (and intra-) generational information exchange are considered vital ingredients in how movement decisions are reached. Yet key information is often missing on the spatial outcomes of such decisions, and questions concerning how migratory traditions are influenced by collective memory, density-dependent and density-independent processes remain...

Data from: Transcriptome profiling of ontogeny in the acridid grasshopper Chorthippus biguttulus

Emma L. Berdan, Jonas Finck, Paul R. Johnston, Isabelle Waurick, Camila J. Mazzoni & Frieder Mayer
Acridid grasshoppers (Orthoptera:Acrididae) are widely used model organisms for developmental, evolutionary, and neurobiological research. Although there has been recent influx of orthopteran transcriptomic resources, many use pooled ontogenetic stages obscuring information about changes in gene expression during development. Here we developed a de novo transcriptome spanning 7 stages in the life cycle of the acridid grasshopper Chorthippus biguttulus. Samples from different stages encompassing embryonic development through adults were used for transcriptomic profiling, revealing patterns of...

Data from: Walking like an ant: a quantitative and experimental approach to understanding locomotor mimicry in the jumping spider Myrmarachne formicaria

Paul S. Shamble, Ron R. Hoy, Itai Cohen & Tsevi Beatus
Protective mimicry, in which a palatable species avoids predation by being mistaken for an unpalatable model, is a remarkable example of adaptive evolution. These complex interactions between mimics, models and predators can explain similarities between organisms beyond the often-mechanistic constraints typically invoked in studies of convergent evolution. However, quantitative studies of protective mimicry typically focus on static traits (e.g. colour and shape) rather than on dynamic traits like locomotion. Here, we use high-speed cameras and...

Data from: Matching seed to site by climate similarity: Techniques to prioritize plant materials development and use in restoration

Kyle D. Doherty, Bradley J. Butterfield & Troy E. Wood
Land management agencies are increasing the use of native plant materials for vegetation treatments to restore ecosystem function and maintain natural ecological integrity. This shift towards the use of natives has highlighted a need to increase the diversity of materials available. A key problem is agreeing on how many, and which, new accessions should be developed. Here we describe new methods that address this problem. Our methods use climate data to calculate a climate similarity...

Data from: Drosophila simulans: a species with improved resolution in evolve and resequence studies

Neda Barghi, Raymond Tobler, Viola Nolte & Christian Schlötterer
The combination of experimental evolution with high-throughput sequencing of pooled individuals—i.e., evolve and resequence (E&R)—is a powerful approach to study adaptation from standing genetic variation under controlled, replicated conditions. Nevertheless, E&R studies in Drosophila melanogaster have frequently resulted in inordinate numbers of candidate SNPs, particularly for complex traits. Here, we contrast the genomic signature of adaptation following ∼60 generations in a novel hot environment for D. melanogaster and D. simulans. For D. simulans, the regions...

Data from: Gene expression differs in codominant prairie grasses under drought

Ava M. Hoffman & Melinda D. Smith
Grasslands of the Central US are expected to experience severe droughts and other climate extremes in the future, yet we know little about how these grasses will respond in terms of gene expression. We compared gene expression in Andropogon gerardii and Sorghastrum nutans, two closely related co-dominant C4 grasses responsible for the majority of ecosystem function, using RNA-seq. We compared Trinity assemblies within each species to determine annotated functions of transcripts responding to drought. Subsequently,...

Data from: Demographic model selection using random forests and the site frequency spectrum

Megan L. Smith, Megan Ruffley, Anahí Espindola, David C. Tank, Jack Sullivan & Bryan C. Carstens
Phylogeographic data sets have grown from tens to thousands of loci in recent years, but extant statistical methods do not take full advantage of these large data sets. For example, approximate Bayesian computation (ABC) is a commonly used method for the explicit comparison of alternate demographic histories, but it is limited by the “curse of dimensionality” and issues related to the simulation and summarization of data when applied to next-generation sequencing (NGS) data sets. We...

Data from: Aneuploidy causes non-genetic individuality

Rebecca R. Beach, Chiara Ricci-Tam, Christopher M. Brennan, Christine A. Moomau, Pei-Hsin Hsu, Bo Hua, Rebecca E. Silberman, Michael Springer & Angelika Amon
Phenotypic variability is a hallmark of diseases involving chromosome gains and losses, such as Down syndrome and cancer. Allelic variances have been thought to be the sole cause of this heterogeneity. Here, we systematically examine the consequences of gaining and losing single or multiple chromosomes to show that the aneuploid state causes non-genetic phenotypic variability. Yeast cell populations harboring the same defined aneuploidy exhibit heterogeneity in cell-cycle progression and response to environmental perturbations. Variability increases...

Data from: The chinchilla as a novel animal model of pregnancy

Emmeli Mikkelsen, Henrik Lauridsen, Per Mose Nielsen, Haiyun Qi, Thomas Nørlinger, Maria Dahl Andersen, Niels Uldbjerg, Christoffer Laustsen, Puk Sandager & Michael Pedersen
Several parameters are important when choosing the most appropriate animal to model human obstetrics, including gestation period, number of fetuses per gestation and placental structure. The domesticated long-tailed chinchilla (Chinchilla lanigera) is a well-suited and appropriate animal model of pregnancy that often will carry only one offspring and has a long gestation period of 105–115 days. Furthermore, the chinchilla placenta is of the haemomonochorial labyrinthine type and is therefore comparable to the human villous haemomonochorial...

Data from: Demographic modelling reveals a history of divergence with gene flow for a glacially tied stonefly in a changing post-Pleistocene landscape

Scott Hotaling, Clint C. Muhlfeld, J. Joseph Giersch, Omar A. Ali, Steve Jordan, Michael R. Miller, Gordon Luikart & David W. Weisrock
Aim: Climate warming is causing extensive loss of glaciers in mountainous regions, yet our understanding of how glacial recession influences evolutionary processes and genetic diversity is limited. Linking genetic structure with the influences shaping it can improve understanding of how species respond to environmental change. Here, we used genome-scale data and demographic modelling to resolve the evolutionary history of Lednia tumana, a rare, aquatic insect endemic to alpine streams. We also employed a range of...

Data from: Complex selection on a regulator of social cognition: evidence of balancing selection, regulatory interactions and population differentiation in the prairie vole Avpr1a locus

Alejandro Berrio, Rafael F. Guerrero, Galina V. Aglyamova, Mariam Okhovat, Mikhail V. Matz & Steven M. Phelps
Adaptive variation in social behavior depends upon standing genetic variation, but we know little about how evolutionary forces shape genetic diversity relevant to brain and behavior. In prairie voles (Microtus ochrogaster), variants at the Avpr1a locus predict expression of the vasopressin 1a receptor in the retrosplenial cortex (RSC), a brain region that mediates spatial and contextual memory; cortical V1aR abundance in turn predicts diversity in space-use and sexual fidelity in the field. To examine the...

Data from: Phylogenomic insights into the evolution of stinging wasps and the origins of ants and bees

Michael G. Branstetter, Bryan N. Danforth, James P. Pitts, Brant C. Faircloth, Philip S. Ward, Matthew L. Buffington, Michael W. Gates, Robert R. Kula & Seán G. Brady
The stinging wasps (Hymenoptera: Aculeata) are an extremely diverse lineage of hymenopteran insects, encompassing over 70,000 described species and a diversity of life history traits, including ectoparasitism, cleptoparasitism, predation, pollen feeding (bees [Anthophila] and Masarinae) and eusociality (social vespid wasps, ants, and some bees) [1]. The most well-studied lineages of Aculeata are the ants, which are ecologically dominant in most terrestrial ecosystems [2], and the bees, the most important lineage of angiosperm-pollinating insects [3]. Establishing...

The Identity and the Dilemma of the Malay Music-Culture of the Urang Pulo Islanders of the Banyak Archipelago, Sumatra: An Ethnographic, Socio-Historical and Music-Analytical Study

Ari Palawi
This thesis investigates the music-cultural identity and conservational dilemma of the hitherto un-researched music-culture of the Islanders (Urang Pulo) of the Banyak Archipelago in Aceh-Singkil Regency off the west coast of Aceh, Indonesia. The Islanders’ dominant concept of identity is coloured by their dominant sikambang music, dance and legend, history of cultural contact with west-coastal Sumatran Malay and offshore island area, Niasan and Simeulue immigration to the Islands, the cultural memory of their former court...

Experimentation, Authority and Situation in Simone de Beauvoir’s The Second Sex

Emma McNicol
In this thesis I read Simone de Beauvoir’s The Second Sex through the lens of her early (and only recently published) writing on Claude Bernard’s experimental approach. In the 1924 essay “Analysis of Claude Bernard’s Introduction to the Study of Experimental Medicine,” Beauvoir endorses Bernard’s critique of “theoretical authority” and certain elements of his experimental approach. The Second Sex redeploys this early criticism of theoretical authority and valorisation of experimentation to produce a critique of...
