title: Seed mass, hardness and phylogeny determine the potential for endozoochory by granivorous waterbirds

description: Field studies have shown that waterbirds, especially members of the
 Anatidae family, are major vectors of dispersal for a broad range of
 plants whose propagules can survive gut passage. Widely adopted dispersal
 syndromes ignore this dispersal mechanism, and we currently have little
 understanding of what traits determine the potential of angiosperms for
 endozoochory by waterbirds. Results from previous experimental studies
 have been inconsistent as to how seed traits affect seed survival and
 retention time in the gut, and have failed to control for the influence of
 plant phylogeny. Using 13 angiosperm species from aquatic and terrestrial
 habitats representing nine families, we examined the effects of seed size,
 shape and hardness on the proportion of seeds surviving gut passage
 through mallards (Anas platyrhynchos), and their retention time within the
 gut. We compiled a molecular phylogeny for these species and controlled
 for the non-independence of taxa due to common descent in our analyses.
 Intact seeds from all 13 species were egested, but seed survival was
 strongly determined by partial effects of seed mass and hardness (wet
 load): species with seeds harder than expected from their size, and
 smaller than expected from their loading, had higher survival. Once
 phylogeny was controlled for, a positive partial effect of seed roundness
 on seed survival was also revealed. Species with seeds harder than
 expected from their size had a longer mean retention time, but no
 phylogenetic signal was found for retention time. Our study is the first
 to demonstrate that seed shape and phylogeny are important predictors of
 seed survival in the avian gut. Our results demonstrate the importance of
 controlling simultaneously for multiple traits, and that relating single
 traits (e.g. seed size) alone to seed survival or retention time is not a
 reliable way to detect important patterns, especially when phylogenetic
 effects are ignored.
description: We conducted three consecutive feeding trials. During each trial,
 each of the eight individual mallards was force-fed with 100 seeds of the
 small-seeded taxa and 50 seeds of the two larger-seeded species<i>
 </i>(<i>Glycyrrhiza </i><i>echinata, Sparganium
 erectum</i>). In order to investigate how seed traits influenced
 seed survival and retention time, we measured the following five traits
 for seeds that had not been ingested by birds: hardness, thousand seed
 mass, volume, water permeability, shape, phylogeny.

title: Data from: Assessing spatial patterns of soil erosion in a high‐latitude rangeland

description: High‐latitude areas are experiencing rapid change: we therefore need a
 better understanding of the processes controlling soil erosion in these
 environments. We used a spatiotemporal approach to investigate soil
 erosion in Svalbarðstunga, Iceland (66° N, 15° W), a degraded rangeland.
 We used three complementary datasets: 1) high‐resolution UAV imagery
 collected from 12 sites (total area ~0.75 km2); 2) historical imagery of
 the same sites; and 3) a simple, spatially‐explicit cellular automata
 model. Sites were located along a gradient of increasing altitude and
 distance from the sea, and varied in erosion severity (5–47% eroded). We
 found that there was no simple relationship between location along the
 environmental gradient and the spatial characteristics of erosion.
 Patch‐size frequency distributions lacked a characteristic scale of
 variation, but followed a power‐law distribution on five of the 12 sites.
 Present total eroded area is poorly related to current, site‐scale levels
 of environmental stress, but the number of small erosion patches did
 reflect site‐level stress. Small (&lt; 25 m2) erosion patches
 clustered near large patches. The model results suggested that the
 large‐scale patterns observed likely arise from strong, local
 interactions, which mean that erosion spreads from degraded areas. Our
 findings suggest that contemporary erosion patterns reflect historical
 stresses, as well as current environmental conditions. The importance of
 abiotic processes to the growth of large erosion patches and their
 relative insensitivity to current environmental conditions makes it likely
 that the total eroded area will continue to increase, despite a warming
 climate and reducing levels of grazing pressure.

title: Hydropeaking affects germination and establishment of riverbank vegetation

description: Hydropeaking, defined as frequent and rapid variation in flow in regulated
 rivers with hydropower plants over a short period of time, usually
 sub-daily to weekly, alters hydraulic parameters such as water levels or
 flow velocity and exerts strong impacts on fluvial ecosystems. We
 evaluated the effects of hydropeaking on riverbank vegetation,
 specifically assessing the germination and establishment of seedlings and
 cuttings of plant species representing a variation in traits. We used
 seeds and seedlings and cuttings varying in size as phytometers, and
 transplanted them to riverbanks both above and below dams used for
 hydropower production in northern Sweden, selected to represent a gradient
 in hydropeaking intensity, and along a free-flowing reach. We also
 analyzed sub-daily water level variables modified by hydropeaking to
 identify variables key in explaining the observed vegetation patterns. We
 found that plant responses to hydropeaking varied with species, with
 flood-intolerant species being the most strongly affected, as early as the
 germination stage. In contrast, seeds of flood-tolerant species managed to
 germinate and survive the early establishment phase, although strong
 erosive processes triggered by hydropeaking eventually caused most of them
 to fail. The fate of flood-intolerant species identifies germination as
 the most critical life-history stage. The depth and frequency of the
 inundation were the leading variables explaining plant responses, while
 the duration of shallow inundation explained little of the variation. The
 rise and fall rates of water levels were key explaining variation in
 germination success. Based on the results, we propose restoration measures
 to enhance establishment of riparian plant communities while minimizing
 the impact on hydropower electricity production. Given the strong decrease
 in the germination of species intolerant to prolonged flooding with
 hydropeaking, planting of seedlings, preferably of large sizes, together
 with restrictions in the operation of the power plant during the
 establishment phase to enhance survival would be the best restoration
 option. Given the high probability of plant uprooting with hydropeaking,
 bank protection measures have the potential to increase riparian-plant
 survival of all species, including flooding tolerant ones.
description: Water level data and vegetation performance data were collected
 from the Ume and Vindel rivers in Northern Sweden, along
 experimental riparian levels parallel to the water edge, in several
 experimental sites per river reach. Water levels were measured by pressure
 transducer data loggers (Rugged Baro and Diver TROLL 100 Data Logger)
 every 15 minutes, during the growing season. Vegetation performance
 involved in-situ measurements of the germination success, stem length and
 whether plants were alive or had been moved or displaced. They also
 involved lab measurements of dry plant biomass.

title: Plasma glycated CD59 predicts early gestational diabetes and large for gestational age newborns

description: Gestational diabetes mellitus (GDM) diagnosed in early pregnancy is a
 health care challenge because it increases the risk of adverse
 outcomes. Plasma glycated CD59 (pGCD59) is an emerging
 biomarker for diabetes and GDM. The aim of this study
 was to assess the performance of pGCD59 as a biomarker
 of early GDM and its association with delivering a large for
 gestational age (LGA) infant. Study: Blood levels
 of pGCD59 were measured in samples from 693 women
 undergoing a 75g, 2-hour oral glucose tolerance test (OGTT) at &lt;20
 weeks gestation in the DALI study: the main analyses included 486
 subjects who had normal glucose tolerance throughout the pregnancy, 207
 who met criteria for GDM at &lt;20 weeks and 77
 diagnosed with GDM at pregnancy week 24-28. Reference tests: 75g, 2-hour
 OGTT adjudicated based on IADPSG criteria. Index test: pGCD59
 ELISA. Primary aim: To assess the performance of pGCD59 to identify women
 with GDM in early pregnancy (GDM&lt;20). Secondary aim: To assess the
 association of pGCD59 with LGA and potentially  others adverse
 neonatal outcomes linked to GDM. Mean pGCD59 levels were
 significantly higher (p-value &lt;0.001) in women
 with GDM&lt;20 (3.9 ±1.1 SPU) than in those
 without (2.7 ±0.7 SPU). pGCD59 accurately
 identified GDM in early pregnancy with an AUC ROC curves of 0.86 (95% CI:
 0.83-0.90). One unit increase in maternal pGCD59 level was
 associated with 36% increased odds of delivering a large for gestational
 age (LGA) infant (odds ratio for LGA vs non-LGA infant: 1.4; 95%CI:
 1.1–1.8; p-value: 0.016).  Our results indicate
 that pGCD59 is a simple and accurate biomarker for
 detection of GDM in early pregnancy and risk assessment of
 LGA.

title: Molecular evolution of phototransduction pathway genes in nocturnal and diurnal fireflies (Coleoptera: Lampyridae)

description: Most organisms are dependent on sensory cues from their environment for
 survival and reproduction. Fireflies (Coleoptera: Lampyridae) represent an
 ideal system for studying sensory niche adaptation due to many species
 relying on bioluminescent communication, as well as a diversity of
 ecology. Here we examine the phototransduction pathway in this non-model
 organism, and provide some of the first evidence for positive selection in
 the PT pathway in insects. Duplications are found in calmodulin,
 inactivation no afterpotential C, inactivation no afterpotential D, and
 transient receptor potential. We also find strong support for positive
 selection in arrestin-2, inactivation no afterpotential D, and transient
 receptor potential, with weak support for positive selection in guanine
 nucleotide-binding protein G(q) subunit alpha and  neither
 inactivation nor afterpotential C. This represents an exciting new avenue
 of study as we seek to further understand these molecular players.

title: Consistent patterns of distractor effects during decision making

description: The value of a third potential option or distractor can alter the way in
 which decisions are made between two other options. Two hypotheses have
 received empirical support: that a high value distractor improves the
 accuracy with which decisions between two other options are made and that
 it impairs accuracy. Recently, however, it has been argued that neither
 observation is replicable. Inspired by neuroimaging data showing that high
 value distractors have different impacts on prefrontal and parietal
 regions, we designed a dual route decision-making model that mimics the
 neural signals of these regions. Here we show in the dual route model and
 empirical data that both enhancement and impairment effects are robust
 phenomena but predominate in different parts of the decision space defined
 by the options’ and the distractor’s values. However, beyond these
 constraints, both effects co-exist under similar conditions. Moreover,
 both effects are robust and observable in six experiments.

title: Reactivity, fate and functional roles of dissolved organic matter in anoxic inland waters

description: The transit of organic matter (OM) through the aquatic compartment of its
 global cycle has been intensively studied, traditionally with a focus on
 the processing and degradation of its dissolved fraction (DOM). Because
 this is so intimately related to oxidation, the notion tenaciously
 persists that where dioxygen (O2) is absent, DOM turnover is markedly
 slowed. In this Opinion Piece, we outline how diverse processes shape,
 transform and degrade DOM also in anoxic aquatic environments, and we
 focus here on inland waters as a particular case study. A suite of
 biogeochemical DOM functions that have received comparatively little
 attention may only be expressed in anoxic conditions, and may result in
 enhanced biogeochemical roles of these deoxygenated habitats on a network
 scale.
description: Literature meta-analysis on the sediment release of dissolved
 organic matter (DOM) to anoxic fresh and marine waters, and the bacterial
 (secondary) production within them. We used data solely from articles that
 explicitly addressed anoxic environments in situ, compared oxic with
 anoxic conditions, or study the implications of anoxic conditions in
 experimental setups.

title: How biomechanics, path-planning and sensing enable gliding flight in a natural environment

description: Gliding animals traverse cluttered aerial environments when performing
 ecologically relevant behaviours. However, it is unknown how gliders
 execute collision-free flight over varying distances to reach their
 intended target. We quantified complete glide trajectories amid obstacles
 in a naturally behaving population of gliding lizards inhabiting a
 rainforest reserve. In this cluttered habitat, the lizards used glide
 paths with fewer obstacles than alternatives of similar distance. Their
 takeoff direction oriented them away from obstacles in their path and they
 subsequently made mid-air turns with accelerations of up to 0.5 g to
 reorient towards the target tree. These manoeuvres agreed well with a
 vision-based steering model which maximized their bearing angle with the
 obstacle while minimizing it with the target tree. Nonetheless,
 negotiating obstacles reduced mid-glide shallowing rates, implying greater
 loss of altitude. Finally, the lizards initiated a pitch-up landing
 manoeuvre consistent with a visual trigger model, suggesting that the
 landing decision was based on the optical size and speed of the target.
 They subsequently followed a controlled-collision approach towards the
 target, ending with variable impact speeds. Overall, the visually guided
 path-planning strategy that enabled collision-free gliding required
 continuous changes in the gliding kinematics such that the lizards never
 attained theoretically ideal steady state glide dynamics.

 (Draco) flying in their natural habitat, collected at the Agumbe
 Rainforest Research Station, Karnataka, India. Data were collected by
 high-speed multi-camera videography and processed as described in the

title: Invasive species and biotic homogenization in temperate aquatic plant communities

description: Aim: Biotic homogenization (BH), a reduction in the distinctness of
 species composition between geographically separated ecological
 communities in a region, is an important but underappreciated potential
 consequence of biological invasions. While BH theory has always considered
 invasions, it has generally been in a relatively narrow context, i.e.,
 that the cosmopolitan nature of invasive species increases BH because of
 their shared presence across many locations. We sought to evaluate this
 component of BH as well as broader effects of invasive species on BH
 through changes in native communities, including overall reductions in
 species richness or shifts in species composition. Location: Minnesota,
 USA Time Period: 2002-2014 Major Taxa Studied: Aquatic macrophytes,
 including both vascular plants and attached macroalgae. Methods: We used
 surveys of aquatic macrophyte communities from 1,102 shallow lakes in
 Minnesota, USA (including 248 lakes with repeated surveys) to evaluate
 relationships between invasion, native species, and BH. Results: We found
 that the presence of invasive species was associated with BH and that this
 pattern was reflected in both the total community (i.e., with invasive
 species included) and in the composition of the native species community
 alone. We found that invaded lakes were more compositionally similar to
 each other than uninvaded lakes, but that both groups were becoming more
 similar over time—despite neither group exhibiting declines in species
 richness. This pattern was largely driven by shifts in the native
 community itself, with common species becoming more widespread and rare
 species becoming rarer. Main Conclusions: Invasive species increase
 measures of community similarity through their own presence in multiple
 locations, and also by influencing the composition of native species.
 These patterns have important implications for conservation and management
 and suggest that BH should be considered more widely in evaluating the
 impacts of biological invasions and developing response strategies.

title: Ectomycorrhizal fungal diversity predicted to substantially decline due to climate changes in North American Pinaceae forests.

description: AIM: Ectomycorrhizal fungi (ECMF) are partners in a globally distributed
 tree symbiosis implicated in most major ecosystem functions. However,
 resilience of ECMF to future climates is uncertain. We forecast these
 changes over the extent of North American Pinaceae forests. LOCATION: 68
 sites from North American Pinaceae forests ranging from Florida to Ontario
 in the east and southern California to Alaska in the west. TAXON:
 Ectomycorrhizal fungi (Asco- and Basidiomycetes). METHODS: We
 characterized ECMF communities at each site using molecular methods and
 modeled climatic drivers of diversity and community composition with
 general additive, generalized dissimilarity models, and Taxonomic
 Indicator Threshold Analysis (TITAN). Next, we projected our models across
 the extent of North American Pinaceae forests and forecast ECMF responses
 to climate changes in these forests over the next 50 years. RESULTS: We
 predict median declines in ECMF species richness as high as 26% in
 Pinaceae forests throughout a climate zone comprising more than 3.5
 million square kilometers of North America (an area twice that of Alaska
 state). Mitigation of greenhouse gas emissions can reduce these declines,
 but not prevent them. The existence of multiple diversity optima along
 climate gradients suggest regionally divergent trajectories for North
 American ECMF, which is corroborated by corresponding ECMF community
 thresholds identified in TITAN models. Warming of forests along the
 boreal-temperate ecotone results in projected ECMF species loss and
 declines in the relative abundance of long-distance foraging ECMF species,
 whereas warming of eastern temperate forests has the opposite effect. MAIN
 CONCLUSIONS: Our results reveal potentially unavoidable ECMF
 species-losses over the next 50 years, which is likely to have profound
 (if yet unclear) effects of ECMF associated biogeochemical cycles.

title: Examining the relationship between processing fluency and memory for source information

description: Familiarity-based processes such as processing fluency can influence
 memory judgements in tests of item recognition. Many conventional accounts
 of source memory assume minimal influence of familiarity on source memory,
 but recent work has suggested that source memory judgements are affected
 when test stimuli are processed with greater fluency as a result of
 priming. The present experiments investigated the relationship between
 fluency and the accuracy of source memory decisions. Participants studied
 words presented with different source attributes. During test, they
 identified words that gradually clarified on screen through progressive
 de-masking, made old/new and source memory judgements, and reported
 confidence ratings for those words. Response times (RTs) recorded from the
 item identification task formed the basis of a fluency measure, and
 identification RTs were compared across categories of item recognition,
 source accuracy, and confidence. Identification RTs were faster in trials
 with correct retrieval of source information compared to trials for which
 source could not be accurately retrieved. These findings are consistent
 with the assumption that familiarity-based processes can contribute to
 source memory judgements.
