#1. Seed mass and plant origin interact to determine species germination patterns
Andrea Vesela, Tomas Dostalek, Maan Rokaya, Zuzana Munzbergova
Ongoing changes in temperature and precipitation regime may have strong impact on vulnerable life-history stages such as germination. Differences in germination patterns among species and populations may reflect their adaptation to conditions of their origin or may be determined by the phylogenetic constrains. These two effects are, however, rarely separated. All the germination patterns may also be modified by seed mass. We studied 40 populations of 14 species of Impatiens coming from Himalayas. Germination of seeds of different origin was tested in four target temperatures, three simulating original conditions plus a warmer climate change scenario. We also studied effect of shorter stratification and warmer temperature in combination as another possible effect of climate change. Original and target climate interacted and had strong impact on total germination, but not on germination speed and seed dormancy. Interaction between seed mass and original climate indicated different germination strategies in light and heavy seeds....

#2. A demographic approach to understanding the effects of climate on population growth
Nicholas M. Caruso, Christina L Staudhammer, Leslie J Rissler
Amphibian life history traits are affected by temperature and precipitation. Yet, connecting these relationships to population growth, especially for multiple populations within a species, is lacking and precludes our understanding of how amphibians are distributed. Therefore, we constructed Integral Projection Models (IPM) for five populations along an elevational gradient to determine how climate and season affects population growth of a terrestrial salamander Plethodon montanus and the importance of demographic vital rates to population growth under varying climate scenarios. We found that population growth was typically higher at the highest elevation compared to the lower elevations whereas varying inactive season conditions, represented by the late fall, winter and early spring, produced a greater variation in population growth than varying active season conditions (late spring, summer, and early fall). Furthermore, survival and growth was consistently more important, as measured by elasticity, compared to fecundity and...

#3. Integrating Economic dynamics into Ecological Networks: The case of fishery sustainability
Paul Glaum, Valentin Cocco, Fernanda S Valdovinos
Understanding and sustainably managing anthropogenic impact on ecosystems requires studying the integrated economic -ecological dynamics driving coupled human-natural systems. Here, we expand ecological network theory to study fishery sustainability by incorporating economic drivers into food-web models to evaluate the dynamics of thousands of single-species fisheries across hundreds of generated food-webs and two management strategies. Analysis reveals harvesting high population biomass species can initially support fishery persistence, but threatens long term economic and ecological sustainability by indirectly inducing extinction cascades in non-harvested species. This dynamic is exacerbated in open access fisheries where profit driven growth in fishing effort increases perturbation strength. Results demonstrate the unique insight into both ecological dynamics and sustainability garnered from considering economically dynamic fishing effort in the network.

#4. Effect of arbuscular mycorrhizal fungi (AMF) and plant growth promoting rhizobacteria (PGPR) on microbial community structure of phenanthrene and pyrene contaminated soils using Illumina HiSeq sequencing.
Wen-bin Li, Wei Li, Li-jun Xing, Shao-xia Guo
In order to determine the influence of arbuscular mycorrhizal fungi (AMF , Glomus versiforme ) and plant growth promoting rhizobacteria (PGPR, Pseudomonas fluorescens , PS2-6) on degradation of phenanthrene (PHE) and pyrene (PYR) and the change of microbial community structure in soils planted with tall fescue ( Festuca elata ), four treatments were set up in phenanthrene (PHE) and pyrene (PYR) contamined soil: i.e., tall fescue (CK), AMF + tall fescue (GV), PGPR + tall fescue (PS) and AMF + PGPR + tall fescue (GVPS), PHE and PYR dissipation in the soil and accumulated in the tall fescue were investigated. Our results showed that highest removal percentage of PHE and PYR in contaminated soil as well as biomass of tall fescue were observed in GVPS. PHE and PYR accumulation by tall fescue roots were higher than shoots, the mycorrhizal status was best manifested in the roots of tall fescue inoculated with GVPS, and GVPS significantly increased the number of PGPR colonization in tall fescue rhizosphere soil. And paired-end Illumina...

#5. Conservation attention necessary across at least 44% of Earth's terrestrial area to safeguard biodiversity
James R Allan, Hugh P Possingham, Scott C Atkinson, Anthony Waldron, Moreno Di Marco, Vanessa M Adams, Stuart H.M. Butchart, Oscar Venter, Martine Maron, Brooke A. Williams, Kendall R Jones, Piero Visconti, Brendan A. Wintle, April E. Reside, James E.M. Watson
More ambitious conservation efforts are needed to stop the global degradation of ecosystems and the extinction of the species that comprise them. Here, we estimate the minimum amount of land needed to secure known important sites for biodiversity, Earth's remaining wilderness, and the optimal locations for adequate representation of terrestrial species distributions and ecoregions. We discover that at least 64 million km2 (43.6% of Earth's terrestrial area) requires conservation attention either through site-scale interventions (e.g. protected areas) or landscape-scale responses (e.g. land-use policies). Spatially explicit land-use scenarios show that 1.2 million km2 of land requiring conservation attention is projected to be lost to intensive human land-use by 2030 and therefore requires immediate protection. Nations, local communities and industry are urged to implement the actions necessary to safeguard the land areas critical for conserving biodiversity.

#6. First record of 'plasticrusts' and 'pyroplastic' from the European Mediterranean Sea
Sonja Marie Ehlers, Julius A Ellrich
We report the presence of 'plasticrusts' and 'pyroplastic' from coastal habitats in Giglio island, Tyrrhenian Sea, Italy. These novel plastic debris types have only recently been described for the first time from Madeira island (NE Atlantic Ocean) and the United Kingdom, respectively. While 'plasticrusts' are generated by sea waves smashing plastic debris against intertidal rocks, 'pyroplastic' derives from (un)deliberately burnt plastic waste. Using Fourier-transform infrared (FTIR) spectroscopy, we identified the 'plasticrust' material as polyethylene (PE) and the 'pyroplastic' material as polyethylene terephthalate (PET). These polymers are widely used in everyday products and, therefore, contribute heavily to plastic pollution in aquatic and terrestrial environments worldwide. Furthermore, our field surveys suggest that 'plasticrust' abundance is related to wave-exposure and that the 'pyroplastic' derived from beverage bottles which we frequently found along the Giglio coast. Overall, our findings corroborate the notion that...

#7. How to characterise shared space use networks
Klara M Wanelik, Damien R Farine
Studying the social behaviour of small or cryptic species often relies on constructing space-sharing networks from sparse point-based observations of individuals. Such an approach assumes that individuals that have greater shared space use will also interact more. However, there is very little guidance on how much data are required to construct meaningful space-sharing networks, or on how to interpret the relationships generated from such networks. In this study, we quantify the robustness of space-sharing networks to different sampling regimes, providing much needed guidance for informing the choice of sampling regime when designing studies to accurately quantify space sharing. We then describe the characteristics of space use in a wild population of field voles ( Microtus agrestis ), and use this empirical dataset to develop a new method for generating shared space use networks which are generally more strongly correlated with the real network, differ less from the real network and are more powerful to detect effects present in...

#8. Phylogenetic and functional diversity have contrasting effects on the ecological functioning of bacterial communities
Constantinos Xenophontos, Martin Taubert, W. Stanley Harpole, Kirsten Küsel
Biodiversity can have a positive impact on ecosystem functions because greater numbers of species, and their associated genetic and functional differences, can contribute at different times and contexts to overall ecosystem functioning. Quantifying the relative contributions of microbial species to ecosystem functioning is challenging, because many species are believed to be functionally redundant, or their function is not known but inferred by their phylogeny. Here, we used synthetic bacterial communities to test the independent effects of two aspects of biodiversity, phylogenetic and functional diversity, on ecosystem functioning, expecting that greater diversity of each would be associated with greater ecosystem function. Moreover, we tested whether the phylogenetic and functional diversities interact in our system and if that interaction results in the amplification of diversity positive effects on ecosystem functions. To study these effects, we used bacterial isolates to construct communities with different diversity traits...

#9. Size, not temperature, drives cyclopoid copepod predation of invasive mosquito larvae
Marie C Russell, Alima Qureshi, Christopher G Wilson, Lauren J Cator
During range expansion, invasive species can experience new thermal regimes. Differences between the thermal performance of local and invasive species can alter species interactions, including predator-prey interactions. The Asian tiger mosquito, Aedes albopictus , is a known vector of several viral diseases of public health importance. It has successfully invaded many regions across the globe and currently threatens to invade regions of the UK where conditions would support seasonal activity. We assessed the functional response and predation efficiency of the cyclopoid copepods Macrocyclops albidus and Megacyclops viridis from South East England, UK against newly-hatched French Ae. albopictus larvae. First, we assessed the functional response of each copepod species at 15, 20, and 25°C. We then examined the predation efficiency of both copepod species at the same three temperatures, holding the density of mosquito larvae prey constant. Predator-absent controls were included in all experiments to account for background prey...

#10. Environmental variables determining the presence of an avian parasite: the case of the Philornis torquans complex (Diptera: Muscidae) in South America
Pablo Fernando Cuervo, Alejandro Percara, Lucas Monje, Pablo Martin Beldomenico, Martin Anibal Quiroga
Philornis flies are exclusive parasites of birds and their nests, being some of them of conservation concern. Despite many studies addressed different aspects of this problem, none have focused on the geographical distribution of these species; relevant information of conservation concern. In this study, besides providing a model map of environmental suitability of the P. torquans complex in South America, we also contributed with data related to the constraints of its abiotic niche. We provided baseline data (supplementary information) on sites where P. torquans complex is present in southern South America, valuable for future Philornis distribution modelling efforts. According to our results, the P. torquans complex is potentially distributed across central-eastern Argentina, mostly restricted to the Pampean and Chaco (eastern Chaco district) biogeographical provinces. The potential distribution of the P. torquans complex is mainly related to the minimum temperature of the coldest month and mean temperature of warmest quarter....
