      Determination of DNA methylation associated with Acer rubrum (red maple) adaptation to metals: analysis of global DNA modifications and methylation-sensitive amplified polymorphism

      Nam-Soo Kim, Min-Ji Im and Kabwe Nkongolo

      Version of Record online: 22 JUL 2016 | DOI: 10.1002/ece3.2320

      Thumbnail image of graphical abstract

      The main objective of the present study was to assess if DNA methylation is involved in A. rubrum adaptation to soil metal contamination. The global modified cytosine ratios in genomic DNA revealed a significant decrease in cytosine methylation in genotypes from a metal-contaminated site compared to uncontaminated populations. Other genotypes from different metal-contaminated sites appear to be recalcitrant to metal-induced DNA alterations even ≥30 years of tree life exposure to nickel and copper. MSAP analysis showed a high level of polymorphisms in both uncontaminated (77%) and metal-contaminated (72%) populations. For methylated loci, molecular variance among and within populations were 1.5% and 13.2%, respectively. These values were low (0.6% for among populations and 5.8% for within populations) for unmethylated loci. Metal contamination is seen to affect methylation of cytosine residues in CCGG motifs in the A. rubrum populations that were analyzed.

      Mitonuclear coevolution as the genesis of speciation and the mitochondrial DNA barcode gap

      Geoffrey E. Hill

      Version of Record online: 22 JUL 2016 | DOI: 10.1002/ece3.2338

      Thumbnail image of graphical abstract

      Animals must have coadapted mitochondrial and nuclear genotypes to enable core respiratory function, and selection for coadaptation leads to divergence between populations in mitonuclear genotype. Barcoding of mitochondrial genes accurately identifies species because species are defined by mitonuclear genotype. Mitonuclear coevolution to achieve better adaptive function of cellular respiration can also drive speciation.

      Seed preferences by rodents in the agri-environment and implications for biological weed control

      Christina Fischer and Manfred Türke

      Version of Record online: 22 JUL 2016 | DOI: 10.1002/ece3.2329

      Thumbnail image of graphical abstract

      The seed fate is one important step in plants’ life cycle and either reduces or facilitates plant recruitment. In a field and a complementary laboratory experiment, we tested small rodents’ seed feeding behavior and their ecosystem functions as seed predators and/or endozoochorous seed dispersers. Our results suggest that voles provide ecosystem services by reducing densities of (common) weed seeds, rather than facilitating plant recruitment by endozoochory. The risk of affecting endangered arable plants by small rodents’ seed predation seems to be low, as these plant species were less preferred than common weed seeds.

      Evolution of opercle bone shape along a macrohabitat gradient: species identification using mtDNA and geometric morphometric analyses in neotropical sea catfishes (Ariidae)

      Madlen Stange, Gabriel Aguirre-Fernández, Richard G. Cooke, Tito Barros, Walter Salzburger and Marcelo R. Sánchez-Villagra

      Version of Record online: 22 JUL 2016 | DOI: 10.1002/ece3.2334

      Thumbnail image of graphical abstract

      A mitochondrial DNA marker proved suitable to detect species distributions and suggest the existence cryptic species contained in Bagre pinnimaculatus. Opercle shape in neotropical sea catfishes (Ariidae) is strongly affected by phylogeny promoting it as a suitable taxonomic tool for species identification. Further, the adaptation to freshwater habitat shows characteristic opercle shape trajectories, which might be useful to detect habitat preferences in fossils.

      Endurance of larch forest ecosystems in eastern Siberia under warming trends

      Hisashi Sato, Hideki Kobayashi, Go Iwahana and Takeshi Ohta

      Version of Record online: 22 JUL 2016 | DOI: 10.1002/ece3.2285

      Thumbnail image of graphical abstract

      Larch forest ecosystem in eastern Siberia is considered to be dependent on near-surface permafrost through its function of inhibiting subsurface water drainage. We examined whether this ecosystem has endurance for a forecasted climatic change by the end of the 21st century. Although surface permafrost is forecasted to be disappeared in eastern Siberia, resulting in subsurface water drainage, as both air temperature and annual precipitation are forecasted to increase, soil water content during growing season would not decrease, and hence, larch forest ecosystem is shown to be sustained in eastern Siberia.

      Pollen transfer in fragmented plant populations: insight from the pollen loads of pollinators and stigmas in a mass-flowering species

      Chloé E. L. Delmas, Thomas L. C. Fort, Nathalie Escaravage and André Pornon

      Version of Record online: 21 JUL 2016 | DOI: 10.1002/ece3.2280

      Understanding the processes by which mate and pollinator limitations affect plant reproduction has become a major scientific challenge in the context of anthropogenic changes. We demonstrate that pollinator limitation decreases the quantity of pollination services while mate limitation decreases both the quantity and quality of pollination services.

      Patterns of genetic diversity of the cryptogenic red alga Polysiphonia morrowii (Ceramiales, Rhodophyta) suggest multiple origins of the Atlantic populations

      Alexandre Geoffroy, Christophe Destombe, Byeongseok Kim, Stéphane Mauger, María Paula Raffo, Myung Sook Kim and Line Le Gall

      Version of Record online: 19 JUL 2016 | DOI: 10.1002/ece3.2135

      Thumbnail image of graphical abstract

      The red alga Polysiphonia morrowii has been reported worldwide and we determine (with combined analyses of chloroplastic and mitochondrial DNA) the origin of the French and Argentine introduced populations. The genetic structure of P. morrowii populations from introduced areas, which displayed high haplotype diversity compared with populations from native area, suggested the occurrence of multiple introduction events. Our study suggests recent recurrent introduction events through human activities and we therefore conclude that P. morrowii is a cryptogenic species.

      Biogeography of dinoflagellate cysts in northwest Atlantic estuaries

      Andrea M. Price, Vera Pospelova, Michael R. S. Coffin, James S. Latimer and Gail L. Chmura

      Version of Record online: 19 JUL 2016 | DOI: 10.1002/ece3.2262

      Thumbnail image of graphical abstract

      A total of 69 surface sediments from 23 northeast USA estuaries, from Maine to Delaware and four estuaries from Prince Edward Island (Canada), were analyzed to determine the effect of estuary type, biogeography and water quality on the spatial distribution of organic walled dinoflagellate cysts. The spatial distribution of cyst taxa was found to reflect biogeographic provinces established by other marine organisms, with Cape Cod separating the northern Acadian province from the southern Virginian province. The large geographic extent of this study, encompassing four main estuary types (riverine, lagoon, coastal embayment, and fjord), allowed us to determine that the type of estuary is an important parameter influencing cyst assemblages.

      The sea urchin Lytechinus variegatus lives close to the upper thermal limit for early development in a tropical lagoon

      Rachel Collin and Kit Yu Karen Chan

      Version of Record online: 17 JUL 2016 | DOI: 10.1002/ece3.2317

      Thumbnail image of graphical abstract

      We tested critical upper thermal limits for various life stages of the tropical urchin L. variegatus and found that early embryonic development (but not fertilization) appears to be the stage most susceptible to acute thermal stress. Growth and survival of larvae raised under a range of temperatures show that they may already occasionally experience conditions that reduce growth and survival at our study site. These results are important because global warming will likely heat tropical nearshore waters and could extirpate species with low thermal tolerances like these important ecosystem engineers.

      Fitness implications of seasonal climate variation in Columbian ground squirrels

      F. Stephen Dobson, Jeffrey E. Lane, Matthew Low and Jan O. Murie

      Version of Record online: 16 JUL 2016 | DOI: 10.1002/ece3.2279

      Seasonal climate variables influence fitness in Columbian ground squirrels. Snow melt-off in spring has gotten later in the past 21 years, and early summer rainfall has become sparser. Both climate variables had significant negative influences on annual fitness, although the latter was a slightly stronger influence.

      Evolution of alternative insect life histories in stochastic seasonal environments

      Sami M. Kivelä, Panu Välimäki and Karl Gotthard

      Version of Record online: 15 JUL 2016 | DOI: 10.1002/ece3.2310

      Thumbnail image of graphical abstract

      We model the effects of stochastic variation in seasonality on the expression of alternative life history phenotypes and the degree of trait differentiation between these alternative phenotypes, using insects as the model system. The results suggest that selection favors the expression of alternative life history phenotypes in stochastically varying seasonal environments, but that trait differentiation is affected by the developmental stage that is used for overwintering. Seasonality itself seems a key factor promoting the evolution of alternative life histories, and environmental stochasticity may modulate their expression.

      We here provide a unique dual dataset combining controlled food and dental microwear textures on a set of 40 domestic sheep. This study explores the variations in dental microwear textures among the guild of browsing ungulates feeding on leaves, fruits, and seeds. More than an experiment to explore the cause of toothwear, this study will be key work for paleoecologists to track the feeding ecology of earliest ruminants.

      Lack of sex-specific movement patterns in an alien species at its invasion front – consequences for invasion speed

      Ivar Herfindal, Claudia Melis, Per-Arne Åhlén and Fredrik Dahl

      Version of Record online: 14 JUL 2016 | DOI: 10.1002/ece3.2300

      Thumbnail image of graphical abstract

      The movement pattern of raccoon dog, an invasive alien species in Europe, is described with particular emphasis on temporal variation in dispersal behaviour in male and females. Dispersal occurred throughout the year, but was most pronounced during the dark hours. Few sex-differences were found in dispersal behaviour, which results in that encounters between dispersing male and female raccoon dogs is likely to occur far from the source population.

      Inter- and intraspecific variation in body- and genome size in calanoid copepods from temperate and arctic waters

      Hans Petter Leinaas, Marwa Jalal, Tove M. Gabrielsen and Dag O. Hessen

      Version of Record online: 14 JUL 2016 | DOI: 10.1002/ece3.2302

      Thumbnail image of graphical abstract

      Four calanoid copepods with populations from arctic and temperate waters, followed Bergmann clines in body size and with correspondingly larger genomes in northern populations, suggesting that body size at least partly is determined by cell size. Interspecific differences were more complex, pointing to phylogeny and life history traits as additional determinant of body size variation among species.

      Dealing with imperfect detectability in SDMs: An approach using time to detection and interval-censored data. We modelled the distribution of fish in a river basin while accounting for imperfect detectability. Data from single visits provided time intervals for first detection of each species; our modelling approach combines occupation-detection modelling with survival analysis techniques.

      Genetic diversity and structuring across the range of a widely distributed ladybird: focus on rear-edge populations phenotypically divergent

      Émilie Lecompte, Mohand-Ameziane Bouanani, Alexandra Magro and Brigitte Crouau-Roy

      Version of Record online: 13 JUL 2016 | DOI: 10.1002/ece3.2288

      Thumbnail image of graphical abstract

      We provide an empirical test of the central-marginal model using a widespread species distributed on the entire Palearctic region, focusing on genetic and phenotypic characteristics of the rear-edge populations. The genetic diversity and differentiation observed is in agreement with the phenotypic structure across species range. A clear genetic break between populations of Algeria, the Eastern Asia and the remaining populations is a dominant feature of the data. We discuss factors, as historical isolation and/or local adaptation, which may have contributed to their distinct genotypic and phenotypic characteristics.

      Coping with potential bi-parental inbreeding: limited pollen and seed dispersal and large genets in the dioecious marine angiosperm Thalassia testudinum

      Brigitta Ine Van Tussenbroek, Tania Valdivia-Carrillo, Irene Teresa Rodríguez-Virgen, Sylvia Nashieli Marisela Sanabria-Alcaraz, Karina Jiménez-Durán, Kor Jent Van Dijk and Guadalupe Judith Marquez-Guzmán

      Version of Record online: 13 JUL 2016 | DOI: 10.1002/ece3.2309

      Thumbnail image of graphical abstract

      We expected bi-parental inbreeding in Thalassia testudinum, a dioecious seagrass with large genets but very limited pollen and seed dispersal; thus, small genetic neighbourhoods. However, kinship and seedling analysis did not find any evidence for this, which may be attributed to a highly dispersed guerrilla-like clonal growth form (which is unusual for a clonal climax species) that increases the probability of crossing between different potentially unrelated genets.
