      When Siberia came to the Netherlands: the response of continental black-tailed godwits to a rare spring weather event (pages 1164–1176)

      Nathan R. Senner, Mo A. Verhoeven, José M. Abad-Gómez, Jorge S. Gutiérrez, Jos C. E. W. Hooijmeijer, Rosemarie Kentie, José A. Masero, T. Lee Tibbitts and Theunis Piersma

      Article first published online: 29 MAY 2015 | DOI: 10.1111/1365-2656.12381

      Thumbnail image of graphical abstract

      This is one of the first studies to document how extreme weather events affect populations at multiple spatial scales, ranging from the local to continental. This enabled the authors to identify how extreme events actually impact individuals and predict what future increases in their occurrence will mean for vulnerable populations.

    2. Wolves adapt territory size, not pack size to local habitat quality (pages 1177–1186)

      Andrew M. Kittle, Morgan Anderson, Tal Avgar, James A. Baker, Glen S. Brown, Jevon Hagens, Ed Iwachewski, Scott Moffatt, Anna Mosser, Brent R. Patterson, Douglas E.B. Reid, Arthur R. Rodgers, Jen Shuter, Garrett M. Street, Ian D. Thompson, Lucas M. Vander Vennen and John M. Fryxell

      Article first published online: 6 APR 2015 | DOI: 10.1111/1365-2656.12366

      Thumbnail image of graphical abstract

      This research addresses a fundamental, broad-scale ecological question – whether territorial carnivores adapt group size or territory size to match local habitat quality – and uses a novel adaptation of a well-established method to provide compelling evidence in support of one theory over another (Photo by Scott Moffatt).

    3. Shape up or ship out: migratory behaviour predicts morphology across spatial scale in a freshwater fish (pages 1187–1193)

      Ben B. Chapman, Kaj Hulthén, Christer Brönmark, P. Anders Nilsson, Christian Skov, Lars-Anders Hansson and Jakob Brodersen

      Article first published online: 11 MAY 2015 | DOI: 10.1111/1365-2656.12374

      Thumbnail image of graphical abstract

      The authors show that intraspecific variation in body morphology can be explained by variation in migratory strategy in a freshwater fish. Migrants exhibit shallower body morphologies than residents, at both the within- and between-population scale. The authors suggest that the migratory morphotype reduces the costs of migrating into high water velocity habitats.

    4. Exploiting the richest patch has a fitness pay-off for the migratory swift parrot (pages 1194–1201)

      Dejan Stojanovic, Aleks Terauds, Martin J. Westgate, Matthew H. Webb, David A. Roshier and Robert Heinsohn

      Article first published online: 14 MAY 2015 | DOI: 10.1111/1365-2656.12375

      Thumbnail image of graphical abstract

      Exploiting the richest patch allowed swift parrots to maintain stable reproductive outcomes irrespective of the particular location where they bred. Unlike sedentary species that often produce few or lower quality offspring when food is scarce, nomadic migration buffered swift parrots against extreme environmental variation.

    5. Migration timing and its determinants for nocturnal migratory birds during autumn migration (pages 1202–1212)

      Frank A. La Sorte, Wesley M. Hochachka, Andrew Farnsworth, Daniel Sheldon, Daniel Fink, Jeffrey Geevarghese, Kevin Winner, Benjamin M. Van Doren and Steve Kelling

      Article first published online: 30 APR 2015 | DOI: 10.1111/1365-2656.12376

      Thumbnail image of graphical abstract

      This study provides the first comprehensive empirical evaluation of the timing and determinants of autumn migration for North American birds. The findings indicate migration timing is dictated by optimality strategies, modified based on the breadth and flexibility of migrant's foraging guild, with declining ecological productivity defining possible resource thresholds during which migration occurs with greatest intensity under weak high-altitude winds.

    1. What doesn't kill you might make you stronger: functional basis for variation in body armour (pages 1213–1221)

      Chris Broeckhoven, Genevieve Diedericks and P. le Fras N. Mouton

      Article first published online: 30 JUL 2015 | DOI: 10.1111/1365-2656.12414

      Thumbnail image of graphical abstract

      While it has been generally assumed that body armour provides protection against a predatory attack, few explicit tests of the hypothesis exists. The paper uses a novel approach to test whether the bite force of four mongoose species is sufficient to penetrate the skins of several armoured cordylid lizards.

    2. Plant resistance reduces the strength of consumptive and non-consumptive effects of predators on aphids (pages 1222–1232)

      Mônica F. Kersch-Becker and Jennifer S. Thaler

      Article first published online: 23 APR 2015 | DOI: 10.1111/1365-2656.12371

      Thumbnail image of graphical abstract

      This study shows that predation risk accounts for most of the total effect of the predator on herbivore dispersal and performance, but the reduction in herbivore population growth occurs largely through consumption. These effects are strongly influenced by plant resistance, suggesting that they are context dependent.

      The role of a dominant predator in shaping biodiversity over space and time in a marine ecosystem (pages 1242–1252)

      Kari E. Ellingsen, Marti J. Anderson, Nancy L. Shackell, Torkild Tveraa, Nigel G. Yoccoz and Kenneth T. Frank

      Article first published online: 24 JUN 2015 | DOI: 10.1111/1365-2656.12396

      Thumbnail image of graphical abstract

      The effects of over-fishing and collapse of large top predators on the broad-scale biodiversity of oceanic ecosystems remains largely unexplored. The results presented provide strong evidence that intensive harvesting (and collapse) of marine apex predators can have large impacts on biodiversity.

      Article first published online: 23 APR 2015 | DOI: 10.1111/1365-2656.12368

      Thumbnail image of graphical abstract

      This study is the first that investigates the effects of habitat fragmentation on host-parasite network architecture taking into account the ongoing dynamics of habitat loss (i.e. the deforestation rate) using specifically developed land covers. The authors found that ongoing fragmentation strongly impacts host-parasite interactions as rodent-helminth network becomes less connected and more modular.

    2. Age-related effects of chronic hantavirus infection on female host fecundity (pages 1264–1272)

      Eva R. Kallio, Heikki Helle, Esa Koskela, Tapio Mappes and Olli Vapalahti

      Article first published online: 15 JUN 2015 | DOI: 10.1111/1365-2656.12387

      Thumbnail image of graphical abstract

      To predict the risks that zoonotic pathogens pose to humans, understanding fitness effects of pathogens upon animal host populations can help. The finding that zoonotic Puumala hantavirus (PUUV) affects the reproduction of its rodent host might influence the pathogen circulation in the host populations in the nature.

    1. Informed herbivore movement and interplant communication determine the effects of induced resistance in an individual-based model (pages 1273–1285)

      Ilan N. Rubin, Stephen P. Ellner, André Kessler and Kimberly A. Morrell

      Article first published online: 30 APR 2015 | DOI: 10.1111/1365-2656.12369

      Thumbnail image of graphical abstract

      Plants can have complex strategies to defend themselves from attacking herbivores, including damage-induced resistance. These induced responses, along with the sharing of information between neighboring plants and from plants to herbivores, can result in unexpected spatial distributions of herbivores and provide a possible ecological benefit to plants.

    2. Spatial distribution of fishes in a Northwest Atlantic ecosystem in relation to risk of predation by a marine mammal (pages 1286–1298)

      Douglas P. Swain, Hugues P. Benoît and Mike O. Hammill

      Article first published online: 8 JUL 2015 | DOI: 10.1111/1365-2656.12391

      Thumbnail image of graphical abstract

      This study demonstrates that Atlantic cod and other large demersal fishes are able to assess predation risk at the scale of a large marine ecosystem. These fishes respond to increasing abundance of a marine mammal predator by increasing their use of lower-risk habitats, resulting in dramatic changes in the spatial structure of this ecosystem.

    1. Optimal population prediction of sandhill crane recruitment based on climate-mediated habitat limitations (pages 1299–1310)

      Brian D. Gerber, William L. Kendall, Mevin B. Hooten, James A. Dubovsky and Roderick C. Drewien

      Article first published online: 18 MAY 2015 | DOI: 10.1111/1365-2656.12370

      Thumbnail image of graphical abstract

      The authors demonstrate how the process of drought across multiple time-scales differentially negatively affects juvenile recruitment of sandhill cranes in the Rocky Mountains. They do so using a predictive framework that ecologists can simultaneously use to investigate ecological hypotheses and explore novel environmental scenarios to help conservation decision makers.

    2. Flowering time of butterfly nectar food plants is more sensitive to temperature than the timing of butterfly adult flight (pages 1311–1321)

      Heather M. Kharouba and Mark Vellend

      Article first published online: 30 APR 2015 | DOI: 10.1111/1365-2656.12373

      Thumbnail image of graphical abstract

      Understanding the phenological temperature sensitivities of interacting species is critical for predicting future changes in the relative timing of life cycle events. The authors compared this sensitivity of butterflies vs. their potential nectar food plants for many pairs of associating species at an unprecedented scale with novel results for plant-insect interactions.

    3. Microhabitat and body size effects on heat tolerance: implications for responses to climate change (army ants: Formicidae, Ecitoninae) (pages 1322–1330)

      Kaitlin M. Baudier, Abigail E. Mudd, Shayna C. Erickson and Sean O'Donnell

      Article first published online: 15 JUN 2015 | DOI: 10.1111/1365-2656.12388

      Thumbnail image of graphical abstract

      This study assesses the role microhabitat and body size play in setting critical thermal maxima (CTmax) among small-bodied ectotherms. The authors show that different microhabitat uses among army ants affect CTmax beyond what is explained by size. This challenges the ecological relevance of models for climate change that fail to account for species differences in habitat use.

      Global patterns and predictors of fish species richness in estuaries (pages 1331–1341)

      Rita P. Vasconcelos, Sofia Henriques, Susana França, Stéphanie Pasquaud, Inês Cardoso, Marina Laborde and Henrique N. Cabral

      Article first published online: 23 APR 2015 | DOI: 10.1111/1365-2656.12372

      Thumbnail image of graphical abstract

      Knowledge on global richness patterns and predictors for estuarine ecosystems is scarce. This study, based on published data, identifies fish species richness patterns and disentangles the relative importance of underlying predictors. Species richness at estuary scale seems defined by predictors that are spatially hierarchical.

    2. Inferring the effects of potential dispersal routes on the metacommunity structure of stream insects: as the crow flies, as the fish swims or as the fox runs? (pages 1342–1353)

      Olli-Matti Kärnä, Mira Grönroos, Harri Antikainen, Jan Hjort, Jari Ilmonen, Lauri Paasivirta and Jani Heino

      Article first published online: 22 JUL 2015 | DOI: 10.1111/1365-2656.12397

      Thumbnail image of graphical abstract

      The authors compared different proxies for dispersal and their effects on metacommunity structuring in stream insects. In particular, the authors focused on cumulative cost distances between sites, i.e., a novel complementary proxy for dispersal.

      Antagonistic effect of helpers on breeding male and female survival in a cooperatively breeding bird (pages 1354–1362)

      Matthieu Paquet, Claire Doutrelant, Ben J. Hatchwell, Claire N. Spottiswoode and Rita Covas

      Article first published online: 30 APR 2015 | DOI: 10.1111/1365-2656.12377

      Thumbnail image of graphical abstract

      The authors investigated for the first time whether the number of helpers was associated with survival probability considering both sex and age in the sociable weaver using multi-event CMR methods. The results illustrate the complexity of fitness costs and benefits underlying cooperative behaviours.

    2. Disentangling direct and growth-mediated influences on early survival: a mechanistic approach (pages 1363–1372)

      Floriane Plard, Nigel G. Yoccoz, Christophe Bonenfant, François Klein, Claude Warnant and Jean-Michel Gaillard

      Article first published online: 13 JUN 2015 | DOI: 10.1111/1365-2656.12378

      Thumbnail image of graphical abstract

      This study shows, using data on a wild population of roe deer, that most factors influencing early survival have indirect effects on early survival though early growth.

      Article first published online: 11 JUN 2015 | DOI: 10.1111/1365-2656.12389

      Thumbnail image of graphical abstract

      The authors provide a new conceptual decomposition of extra-pair reproductive success (EPRS), a key component of male fitness in socially monogamous systems, into life-history subcomponents. They apply this decomposition to show that, in song sparrows, the probability of siring an available offspring is the primary source of genetic variation in EPRS.

      Plasticity in energy metabolism may help organisms cope with environmental change but the fitness consequences of such plasticity are not well known. The authors show here that shifts in baseline metabolism help to maximize the growth of juvenile brown trout under the constraints imposed by changes in food availability.

      Article first published online: 15 JUL 2015 | DOI: 10.1111/1365-2656.12385

      Thumbnail image of graphical abstract

      This is the first study to establish the chronology of population growths and declines for a lemming species over multiple years. The authors show that lemmings declined during late summer and fall and that summer population decline are driven by low survival while winter growth depends on reproduction.

    2. Population density and climate shape early-life survival and recruitment in a long-lived pelagic seabird (pages 1423–1433)

      Using data from a 48-year longitudinal study, the authors estimate both early life survival and recruitment probability in the wandering albatross. In addition to providing the first 2 years of juvenile survival of an albatross species, this study documented the first evidence for density dependence juvenile mortality in a seabird species.

      Article first published online: 3 JUL 2015 | DOI: 10.1111/1365-2656.12393

      Thumbnail image of graphical abstract

      The authors used a mass-and-age structured model of a roe deer population to investigate the influence of unmeasured individual differences on population dynamics. It was found that unmeasured individual differences impacted weakly on parameters describing population dynamics once individual heterogeneity related to mass and age had been included in the model.

    4. Disentangling trait-based mortality in species with decoupled size and age (pages 1446–1456)

      Article first published online: 14 JUL 2015 | DOI: 10.1111/1365-2656.12399

      Thumbnail image of graphical abstract

      Size and age predict mortality in many organisms, but usually in ontogenetically opposing directions: predation mortality is often intensified on smaller individuals whereas senescence mortality impacts on older individuals. When size and age are decoupled, the authors demonstrate that modeling mortality as an aggregate function of both traits improves model skill. Image credits - G. Stoyle (top, bottom); P.
