    1. Disentangling plant and soil microbial controls on carbon and nitrogen loss in grassland mesocosms

      Franciska T. De Vries, Helene Bracht Jørgensen, Katarina Hedlund and Richard D. Bardgett

      Article first published online: 27 FEB 2015 | DOI: 10.1111/1365-2745.12383

      Our results show that changes in plant and microbial communities both individually and interactively modify C and N loss from grasslands. Moreover, our results suggest that soil microbial communities typical of extensively managed grassland might counteract, or delay, the negative consequences of fertilisation on plant diversity and ecosystem functioning.

    2. Long-term C, N and P allocation to reproduction in Bornean tropical rain forests

      Kanehiro Kitayama, Yuki Tsujii, Ryota Aoyagi and Shin-ichiro Aiba

      Article first published online: 19 FEB 2015 | DOI: 10.1111/1365-2745.12379

      We continued monitoring litterfall dynamics and estimated the amount of phosphorus that tropical trees invested to reproduction in eight Bornean rain forests over a 10-year period from 1996 to 2006. This graph demonstrates the dynamics of reproductive organs in two forests. Reproductive events appear to be highly irregular and gregarious. However, our study indicates that these irregular events are regulated by phosphorus at the level of overall long-term mean.

    3. Niche construction by growth forms is as strong a predictor of species diversity as environmental gradients

      Kari Anne Bråthen and Virve Tuulia Ravolainen

      Article first published online: 16 FEB 2015 | DOI: 10.1111/1365-2745.12380

      In this study, we provide conceptual and empirical evidence for collective niche construction as a powerful ecological process that affects species diversity and that can act independently of environmental conditions. Species sharing a single trait or species belonging to a growth form can act as collective niche constructors, and as exemplified for growth forms in this study, be important predictors of species diversity in ecological communities.

    4. High-elevation range limit of an annual herb is neither caused nor reinforced by declining pollinator service

      Anna L. Hargreaves, Jennifer L. Weiner and Christopher G. Eckert

      Article first published online: 16 FEB 2015 | DOI: 10.1111/1365-2745.12377

      We found no evidence for pollination failure towards Rhinanthus minor's upper range edge. Floral density declined at the edge, but pollinator abundance, visitation rates, and seed set did not. Autonomous selfing contributed strongly to mating system and demography, buffering against pollination stochasticity. As many angiosperms are self-compatible, reproductive assurance may reduce pollination's importance in limiting plant distributions, compared to other biotic interactions.

    5. Functional differences between dominant grasses drive divergent responses to large herbivore loss in mesic savanna grasslands of North America and South Africa

      Elisabeth J. Forrestel, Michael J. Donoghue and Melinda D. Smith

      Article first published online: 11 FEB 2015 | DOI: 10.1111/1365-2745.12376

      Our study demonstrates that savanna grassland communities with different biogeographic and grazing histories respond differently to the removal of large herbivores, and that climate, fire, and grazing are interactive forces in maintaining savanna grassland diversity and function. We show that the functional attributes of the dominant grasses, which are in part driven by the biogeographic and grazing history experienced, are the most relevant in predicting the response of savanna ecosystems to the loss of large herbivores.

    6. Tropical trees in a wind-exposed island ecosystem: height-diameter allometry and size at onset of maturity

      Sean C. Thomas, Adam R. Martin and Erin E. Mycroft

      Article first published online: 11 FEB 2015 | DOI: 10.1111/1365-2745.12378

      Height-diameter (H-D) allometry is an important axis of variation among tree species critical to predicting carbon stocks. Observed H-D allometries in the Dominica, West Indies, a global wind hotspot, diverge strongly from global continental patterns and are strongly asymptotic.

    7. Life history evolution under climate change and its influence on the population dynamics of a long-lived plant

      Jennifer L. Williams, Hans Jacquemyn, Brad M. Ochocki, Rein Brys and Tom E. X. Miller

      Article first published online: 31 JAN 2015 | DOI: 10.1111/1365-2745.12369

      Thumbnail image of graphical abstract

      Our results illustrate that long-lived organisms can exhibit complex demographic responses to changing climate regimes. Additionally, they highlight that long-term evolutionary responses may be in opposing directions to short-term responses to climate. Finally, they emphasize the need for demographic models to integrate ecological and evolutionary influences of climate across the life cycle.

    1. Biomass–density data analysis: a comment on Cabaço et al. (2013)

      Vasco M. N. C. S. Vieira, Francisco Leitão and Marcos Mateus

      Article first published online: 27 JAN 2015 | DOI: 10.1111/1365-2745.12294

      Thumbnail image of graphical abstract

      Some mistakes present in Cabaço et al. are of a generalistic nature, that is can occur in any other subject as they report to general xy data analysis. Besides, other mistakes were identified, specific to biomass–density relations. This presentation intends to help ecological researchers by pinpointing the sources of bias.
