      Life history variation in Barents Sea fish: implications for sensitivity to fishing in a changing environment

      Magnus A. Wiedmann, Raul Primicerio, Andrey Dolgov, Camilla A. M. Ottesen and Michaela Aschan

      Article first published online: 2 SEP 2014 | DOI: 10.1002/ece3.1203

      Thumbnail image of graphical abstract

      Life history traits can be used to assess species' response to exploitation and environmental change. Focusing on the Barents Sea fish community, we show that climate change induce a borealization of fish communities in the Arctic, and show explicitly how this promotes changes in the sensitivity to fishing. Our findings should be of interest to ecologists as well as managers.

      Clutch size varies consistently with nest size among species of birds, albeit in a species-specific manner according to 121 slope estimates of the relationship between clutch size and nest size based on 17,472 clutches. The relationship between clutch size and nest size is causal as shown by three experiments. The reaction norm for clutch size variation with nest size shows an increase at small nest box sizes, but a leveling off at larger nest box sizes. These findings have implications for population studies of hole nesting birds (and other nest-building animals) because clutch size and hence parental care and reproductive output will in a species-specific manner depend on the choice of nest box size by scientists.

      Abundance, diversity, and feeding behavior of coral reef butterflyfishes at Lord Howe Island

      Morgan S. Pratchett, Andrew S. Hoey, Christopher Cvitanovic, Jean-Paul A. Hobbs and Christopher J. Fulton

      Article first published online: 2 SEP 2014 | DOI: 10.1002/ece3.1208

      Thumbnail image of graphical abstract

      This study examined correlates of abundance for coral reef butterflyfishes at Lord Howe Island, which is the world's southernmost coral reef. Contrary to expectations, there was no relationship between abundance and geographic range; The single most abundant butterflyfish was a restricted range endemic, which is also seemingly very specialised in terms of its’ diet.

      Sperm mixing in the polyandrous leaf-cutting ant Acromyrmex echinatior

      Marlene Stürup, David R. Nash, William O. H. Hughes and Jacobus J. Boomsma

      Article first published online: 2 SEP 2014 | DOI: 10.1002/ece3.1176

      Thumbnail image of graphical abstract

      We analyzed long- and short-term variation in sperm use in a multiple mated, long lived ant species, by genotyping batches of eggs, as well as worker cohorts. We found no temporal variation in either egg paternity or patriline distributions in worker cohorts, consistent with expectations if queens are to maximize the benefits of genetic diversity in the colony.

      Historical land-use and landscape change in southern Sweden and implications for present and future biodiversity

      Qiao-Yu Cui, Marie-José Gaillard, Geoffrey Lemdahl, Li Stenberg, Shinya Sugita and Ganna Zernova

      Article first published online: 1 SEP 2014 | DOI: 10.1002/ece3.1198

      Thumbnail image of graphical abstract

      We studied the last three centuries of land-use history in central Småland (Southern Sweden) using historical maps, pollen records from three small bogs and models of the relationship between pollen and vegetation (the Landscape Reconstruction Algorithm, LRA). The aims of the study is to (1) evaluate the performance of the LRA for quantitative pollen-based reconstructions of past landscape and (2) discuss the impact of recent land-use changes (over the last three centuries) on changes in biodiversity (mainly landscape diversity and beetle fauna). The results indicate that the LRA is a robust modelling approach to translate pollen data into vegetation/plant cover, and that the transformation of the landscape since the 18th century strongly diminished biodiversity both at the landscape and species level.

      Optimizing occupancy surveys by maximizing detection probability: application to amphibian monitoring in the Mediterranean region

      Maud Petitot, Nicolas Manceau, Philippe Geniez and Aurélien Besnard

      Article first published online: 28 AUG 2014 | DOI: 10.1002/ece3.1207

      Thumbnail image of graphical abstract

      The aim of this study was to define an optimised survey protocol for the Mediterranean amphibian community. We demonstrated the detection probability of amphibians sharply differed between species, the survey method used and the date of the survey. These three covariates also interacted. Thus a minimum of three visits spread over the breeding season, using a combination of all three survey methods, is needed to reach a 95% detection level for all species in the Mediterranean region.

      Choosing and using diversity indices: insights for ecological applications from the German Biodiversity Exploratories

      E. Kathryn Morris, Tancredi Caruso, François Buscot, Markus Fischer, Christine Hancock, Tanja S. Maier, Torsten Meiners, Caroline Müller, Elisabeth Obermaier, Daniel Prati, Stephanie A. Socher, Ilja Sonnemann, Nicole Wäschke, Tesfaye Wubet, Susanne Wurst and Matthias C. Rillig

      Article first published online: 28 AUG 2014 | DOI: 10.1002/ece3.1155

      Thumbnail image of graphical abstract

      Biodiversity is a difficult concept to quantify, partly because of its multidimensional nature, and many simple to complex indices have been developed for this purpose. We collected data on diversity of herbaceous plants, arbuscular mycorrhizal fungi, aboveground arthropods, belowground insect larvae, and Plantago lanceolata molecular and chemical diversity in 60 temperate grasslands and calculated a variety of simple to complex diversity indices for each (S, H', D1, D2, E, BP). While these common diversity indices appeared interchangeable in simple analyses quantifying changes in diversity, when quantifying interactions between diversities the conclusions varied with the index chosen.

      Elevation-dependent responses of tree mast seeding to climate change over 45 years

      Robert B. Allen, Jennifer M. Hurst, Jeanne Portier and Sarah J. Richardson

      Article first published online: 28 AUG 2014 | DOI: 10.1002/ece3.1210

      Thumbnail image of graphical abstract

      Forty five year trends in tree seed production are tested for along an elevation gradient, in relation to temporal changes in climate, using seed count data from a southern hemisphere beech forest. We demonstrate a trend of increasing seed production, that strengthens with increasing elevation, and significant changes in four seasonal climate variables shown to strongly relate to variation in seeding. Regression coefficients for climate variables were consistent with increased seed production. The greater influence of changes in climate on seed production at higher elevations is interpreted as the result of climate driven changes in soil nutrient availability at higher elevations rather than the direct effects of climate change.

      Copepods can rapidly adapt to toxic algae. We rigorously falsified the hypothesis that a sodium channel mutation was related to adaptation to toxic Red-Tide toxins.

      The aging biological clock in Neurospora crassa

      Mary E. Case, James Griffith, Wubei Dong, Ira L. Tigner, Kimberly Gaines, James C. Jiang, S. Michal Jazwinski, Jonathan Arnold and forthe Georgia Centenarian Study

      Article first published online: 22 AUG 2014 | DOI: 10.1002/ece3.1202

      Thumbnail image of graphical abstract

      We establish a mechanistic link between aging and the biological clock through lipid metabolism. The hypothesis is that lipid metabolism provides a shared mechanism to deal with stress in aging and stresses from living in a periodic environment, and we also identify two new genes that affect the clock mechanism. This link of aging and the clock is relevant to understanding diapause in insects, Sundowner's Syndrome in the elderly, how the biological clock functions, and the evolution of circadian rhythms.

      The effect of call libraries and acoustic filters on the identification of bat echolocation

      Matthew J. Clement, Kevin L. Murray, Donald I. Solick and Jeffrey C. Gruver

      Article first published online: 21 AUG 2014 | DOI: 10.1002/ece3.1201

      Thumbnail image of graphical abstract

      We demonstrate methods to isolate and select bat echolocation from sound files using computer filters. Such methods contribute to species identification by replacing ad hoc methods that are less objective and repeatable. We also demonstrate that cross-validation of species identification models with an independent call library yields lower classification success, indicating that the accuracy of acoustic surveys may be lower than commonly reported.

      Panmixia defines the genetic diversity of a unique arthropod-dispersed fungus specific to Protea flowers

      Janneke Aylward, Léanne L. Dreyer, Emma T. Steenkamp, Michael J. Wingfield and Francois Roets

      Article first published online: 21 AUG 2014 | DOI: 10.1002/ece3.1149

      Thumbnail image of graphical abstract

      Using microsatellite markers, the extent of vertical and lateral dispersal of Knoxdaviesia proteae – a Protea-associated ophiostomatoid fungus – was investigated in Protea repens. Exceptionally high genetic diversity was found in the investigated population, likely caused by regular gene flow and an outcrossing. It appears that random long distance dispersal, facilitated by beetles, plays a primary role in the movement of this fungus.

      Integrative tracking methods elucidate the evolutionary dynamics of a migratory divide

      Allison H. Alvarado, Trevon L. Fuller and Thomas B. Smith

      Article first published online: 20 AUG 2014 | DOI: 10.1002/ece3.1205

      Thumbnail image of graphical abstract

      Migratory divides, the boundary between adjacent bird populations that migrate in different directions, are of considerable interest to evolutionary biologists because of their alleged role in promoting reproductive divergence and speciation. Here we integrate multiple approaches by using genetic, geolocator, and morphological data to investigate a migratory divide in hermit thrushes (Catharus guttatus). We discuss our results in the context of reproductive isolating mechanisms associated with migration patterns that have long been hypothesized to promote divergence across migratory divides.

      Demographic histories and genetic diversities of Fennoscandian marine and landlocked ringed seal subspecies

      Tommi Nyman, Mia Valtonen, Jouni Aspi, Minna Ruokonen, Mervi Kunnasranta and Jukka U. Palo

      Article first published online: 19 AUG 2014 | DOI: 10.1002/ece3.1193

      Thumbnail image of graphical abstract

      Ringed seals inhabiting Lake Saimaa in Finland and Lake Ladoga in Russia descend from marine seals that became trapped in the lakes after the last Ice age. The critically endangered Saimaa ringed seals possess very little genetic variation in comparison to their relatives in Lake Ladoga, while the latter are nearly as diverse as the large source population in the Baltic Sea. Our approximate Bayesian computation analyses based on microsatellite and mtDNA data shed light on the demographic processes underlying the very disparate levels of genetic diversity in the three Fennoscandian ringed seal subspecies.

      Genetic and metal analyses of fragmented populations of Betula papyrifera (Marsh) in a mining reclaimed region: identification of population–diagnostic molecular marker

      Gabriel Theriault, Kabwe K. Nkongolo and Paul Michael

      Article first published online: 19 AUG 2014 | DOI: 10.1002/ece3.1195

      Thumbnail image of graphical abstract

      The total heavy metal levels in soil were found to be high, but the availability of these metals was much lower. We found that Betula papyrifera is a Ni and Zn accumulator with a translocation factor of 6.4 and 81, respectively and an indicator of Cu and Pb. The levels of genetic variation were low to moderate. Contrary to our hypothesis, the gene flow among the fragmented B. papyrifera populations were low and population differentiation was relatively high in the reclaimed mining region. No association between soil metal content and population sustainability was established.

      Ecological differentiation between the the black- and red-spotted tokay was substantially detected, further supporting taxonomic distinct between them. Niche divergence along the environmental axes is highly associated with physiological temperature and precipitation, shaping their distribution patters.

      Parasitism in early life: environmental conditions shape within-brood variation in responses to infection

      Hanna M. V. Granroth-Wilding, Sarah J. Burthe, Sue Lewis, Thomas E. Reed, Katherine A. Herborn, Mark A. Newell, Emi A. Takahashi, Francis Daunt and Emma J. A. Cunningham

      Article first published online: 18 AUG 2014 | DOI: 10.1002/ece3.1192

      Thumbnail image of graphical abstract

      We show that environmental conditions can alter how different family members respond to parasitism. Both can shape developmental trajectories of juvenile hosts, influence the outcome of family conflict and contribute to variation in individual success. Quantifying inter-annual differences in breeding conditions was key to explaining why responses to parasitism varied.

      Changes in pollinator fauna affect altitudinal variation of floral size in a bumblebee-pollinated herb

      Yusuke Nagano, Kota Abe, Tomoaki Kitazawa, Mitsuru Hattori, Akira S. Hirao and Takao Itino

      Article first published online: 18 AUG 2014 | DOI: 10.1002/ece3.1191

      Thumbnail image of graphical abstract

      Altitudinal floral size variation of Campanula punctata var. hondoensis in 12 populations in three mountain regions of central Japan was correlated with the size of the local bumblebee pollinator, but not with altitude itself. Pollen removal from flower styles onto bees (plant's male fitness) was strongly influenced by the size match between flower style length and pollinator mouthpart length. These results strongly suggest that C. punctata floral size is under pollinator-mediated selection, and that a geographic mosaic of locally adapted C. punctata exists at fine spatial scale.

      Inappropriate analysis does not reveal the ecological causes of evolution of stickleback armour: a critique of Spence et al.

      Andrew D. C. MacColl and Beth Aucott

      Article first published online: 14 AUG 2014 | DOI: 10.1002/ece3.1179

      Thumbnail image of graphical abstract

      In a recent paper Spence et al. sought to identify the ecological causes of morphological evolution in three-spined sticklebacks Gasterosteus aculeatus, by examining phenotypic and environmental variation between populations on the island of North Uist, Scotland. However, by using simple qualitative assessments of phenotype and inappropriate measures of environmental variation Spence et al. have come to a conclusion that is diametrically opposite to that which we have arrived at in studying the same populations.

      Can phenotypic rescue from harvest refuges buffer wild sheep from selective hunting?

      Fanie Pelletier, Marco Festa-Bianchet, Jon T. Jorgenson, Chiarastella Feder and Anne Hubbs

      Article first published online: 14 AUG 2014 | DOI: 10.1002/ece3.1185

      Very few articles have assessed the effectiveness of refuges to mitigate the effects of selective harvesting. Our analyses suggest that although rams shot near harvest refuges are slightly larger and older, refuges did not appear to buffer wild bighorn sheep from the selective effect of unlimited, phenotype-based trophy hunting.

      Time-series explained the mechanism in population dynamics of the cotton bollworm. Negative density dependence regulates the population dynamics of the pest, and warming and declining rainfall weaken the strength of density dependence. Weakening density dependence from exogenous factors triggers the pest outbreaks.

      Experimental evidence that the Ornstein-Uhlenbeck model best describes the evolution of leaf litter decomposability

      Xu Pan, Johannes H. C. Cornelissen, Wei-Wei Zhao, Guo-Fang Liu, Yu-Kun Hu, Andreas Prinzing, Ming Dong and William K. Cornwell

      Article first published online: 6 AUG 2014 | DOI: 10.1002/ece3.1115

      It is unknown how leaf litter decomposability, as an important effect trait, changed through plant history as a leaf ‘afterlife’ integrator of the evolution of multiple underlying traits upon which adaptive selection must have acted. We provided experimental evidence that Ornstein-Uhlenbeck model best describes the evolution of leaf litter decomposability.

      The impact of transmission mode on the evolution of benefits provided by microbial symbionts

      Jason W. Shapiro and Paul E. Turner

      Article first published online: 6 AUG 2014 | DOI: 10.1002/ece3.1166

      Thumbnail image of graphical abstract

      We explore how symbiont-provided benefits evolve when there exists a mechanism (e.g., pleiotropy or partner choice by the host) that creates a positive covariance between the rate of horizontal transmission and the amount of benefits produced by the symbiont. In many cases, increasing the rate of susceptible host immigration can increase the rate of benefit evolution. Surprisingly, increasing the rate of vertical transmission does not always lead to stronger selection for greater benefits.

      A heterogeneous thermal environment enables remarkable behavioral thermoregulation in Uta stansburiana

      Maria Goller, Franz Goller and Susannah S. French

      Article first published online: 5 AUG 2014 | DOI: 10.1002/ece3.1141

      The availability of a variety of thermal microhabitats allows an individual to behaviorally thermoregulate. Structural complexity may therefore be an important factor in thermoregulatory potential. Mean lizard temperature was between 36°C and 38°C in a broad range of microhabitat temperatures (mean range of 11°C within 1–2 m2).

      Inbreeding alters intersexual fitness correlations in Drosophila simulans.

      Eoin Duffy, Richa Joag, Jacek Radwan, Nina Wedell and David J. Hosken

      Article first published online: 5 AUG 2014 | DOI: 10.1002/ece3.1153

      Thumbnail image of graphical abstract

      Intersexual fitness correlations may vary the segregating genetic variation present, and one way to alter genetic variation is via inbreeding. We test the interesexual correlation for fitness at various stages of inbreeding and find the sign of the association changes. This has implications for sexual selection and the types of genetic variation maintained in populations.
