title: The biotic interactions hypothesis partially explains bird species turnover along a lowland Neotropical precipitation gradient

description: Aim We evaluated the influence of climate in determining bird communities
 along precipitation gradients. We argue that mechanisms responsible for
 community turnover along precipitation gradients are similar to mechanisms
 operating along temperature and latitudinal gradients. We test the
 hypothesis that environmental conditions affect community
 composition in dry forests, whereas biotic interactions affect community
 composition in wet forests. Location Low-elevation forests along a
 precipitation gradient in Colombia where precipitation ranges from 700 –
 4000 mm annually but neither temperature or elevation change. Time period
 Present day Major Taxa Studied Tropical Forest Birds. Methods We performed
 291 bird counts in nine study areas across the ~3000 mm range of variation
 in precipitation. In each locality we obtained climatic characteristics,
 and a phylogenetic, morphological and physiological proxy data set to test
 predictions about the evolutionary relationships and distribution of
 traits in each community.  Results Bird communities changed
 abruptly along the precipitation gradient and could be divided into dry
 and wet forest communities. Analyses of phylogenetic relationships, trait
 space, and observations at nests suggested that environmental filtering is
 more important in dry forest, especially for breeding. In contrast, we
 found little evidence that competition was more important in wet forest.
 Nest predation or competition for nest space, however, may be more
 critical in wetter forests. Conclusions The two distinct bird communities
 we documented suggest that lowland precipitation gradients, where
 temperature is constant can be as important as temperature gradients in
 generating high beta diversity. We conclude that the breeding process in
 bird communities might be crucial for determining community assembly along
 environmental gradients. Given that recent population declines in tropical
 birds have been attributed to changes in precipitation, by understanding
 the mechanisms underlying community assembly along precipitation gradients
 our study may improve our ability to understand those declines and predict
 the effects of climate change on neotropical avifauna.

title: Data from: Is embryo abortion a postzygotic barrier to gene flow between Littorina ecotypes?

description: Genetic incompatibilities contribute to reproductive isolation between
 many diverging populations, but it is still unclear to what extent they
 play a role if divergence happens with gene flow. In contact zones between
 the "Crab" and "Wave" ecotypes of the snail Littorina
 saxatilis divergent selection forms strong barriers to gene flow, while
 the role of postzygotic barriers due to selection against hybrids remains
 unclear. High embryo abortion rates in this species could indicate the
 presence of such barriers. Postzygotic barriers might include genetic
 incompatibilities (e.g. Dobzhansky-Muller incompatibilities) but also
 maladaptation, both expected to be most pronounced in contact zones. In
 addition, embryo abortion might reflect physiological stress on females
 and embryos independent of any genetic stress. We examined all embryos of
 &gt;500 females sampled outside and inside contact zones of three
 populations in Sweden. Females' clutch size ranged from 0 to 1011
 embryos (mean 130±123) and abortion rates varied between 0 and100% (mean
 12%). We described female genotypes by using a hybrid index based on
 hundreds of SNPs differentiated between ecotypes with which we
 characterised female genotypes. We also calculated female SNP
 heterozygosity and inversion karyotype. Clutch size did not vary with
 female hybrid index and abortion rates were only weakly related to hybrid
 index in two sites but not at all in a third site. No additional variation
 in abortion rate was explained by female SNP heterozygosity, but increased
 female inversion heterozygosity added slightly to increased abortion. Our
 results show only weak and probably biologically insignificant postzygotic
 barriers contributing to ecotype divergence and the high and variable
 abortion rates were marginally, if at all, explained by hybrid index of
 females.

title: Using proxies of microbial community‐weighted means traits to explain the cascading effect of management intensity, soil and plant traits on ecosystem resilience in mountain grasslands

description: 1. Trait-based approaches provide a framework to understand the role of
 functional biodiversity on ecosystem functioning under global change.
 While plant traits have been reported as potential drivers of soil
 microbial community composition and resilience, studies directly assessing
 microbial traits are scarce, limiting our mechanistic understanding of
 ecosystem functioning. 2. We used microbial biomass and enzyme
 stoichiometry, and mass-specific enzymes activity as proxies of microbial
 community-weighted mean (CWM) traits, to infer trade-offs in microbial
 strategies of resource use with cascading effects on ecosystem resilience.
 We simulated a drought event on intact plant-soil mesocosms extracted from
 mountain grasslands along a management intensity gradient. Ecosystem
 processes and properties related to nitrogen cycling were quantified
 before, during and after drought to characterize ecosystem resilience. 3.
 Soil microbial CWM traits and ecosystem resilience to drought were
 strongly influenced by grassland type. Structural equation modelling
 revealed a cascading effect from management to ecosystem resilience
 through modifications in soil nutrients, and plant and microbial CWM
 traits. Overall, our results depict a shift from high investment in
 extracellular enzymes in nutrient poor soils (oligotrophic strategy), to a
 copiotrophic strategy with low microbial biomass N:P and low investment in
 extracellular enzymes associated with exploitative plant traits in
 nutrient rich soils. 4. Microbial CWM traits responses to management
 intensity were highly related to ecosystem resilience. Microbial
 communities with a copiotrophic strategy had lower resistance but higher
 recovery to drought, while microbial communities with an oligotrophic
 strategy showed the opposite responses. The unexpected trade-off between
 plant and microbial resistance suggested that the lower resistance of
 copiotrophic microbial communities enabled plant resistance to drought. 5.
 Synthesis Grassland management has cascading effects on ecosystem
 resilience through its combined effects on soil nutrients and plant traits
 propagating to microbial traits and resilience. We suggest that
 intensification of permanent grassland management and associated increases
 in soil nutrient availability decreased plant-microbe competition for N
 under drought through the selection of drought-sensitive microbial
 communities with a copiotrophic strategy that promoted plant resistance.
 Including proxies of microbial CWM traits into the functional trait
 framework will strengthen our understanding of soil ecosystem functioning
 under global change.

title: Reduced cooperative courtship behavior as a cost of high testosterone in a lekking passerine bird

description: Many studies have identified the reproductive benefits of cooperative
 behaviors, yet few have identified the mechanisms that underlie these
 behaviors. Mechanistic studies can inform our understanding of why some
 individuals are more or less cooperative as well as identify the
 physiological constraints imposed upon the evolution of reproductive
 traits. Male wire-tailed manakins (Pipra filicauda) exhibit cooperative
 courtship behaviors and more cooperative territory-holders have been shown
 to exhibit higher reproductive success. To begin to understand the
 proximate basis of cooperative display behaviors, we conducted both an
 observational study and an experimental study. Because coordinated
 courtship displays underlie this form of cooperation, our study also
 examined both the hormonal and social drivers of individual variation in
 courtship behavior more broadly (e.g., display rates). Our observational
 study revealed that males with higher testosterone levels performed fewer
 cooperative display bouts. In addition, our experimental implant study,
 males that received a testosterone-implant significantly decreased the
 proportion of their displays that were cooperative. We found no
 relationship between an individual’s courtship display effort (i.e.,
 display rate and time spent performing courtship displays) and circulating
 testosterone in either study. However, more cooperative males spent a
 greater proportion of time performing courtship displays than did less
 cooperative males, suggesting that testosterone may indirectly mediate
 courtship display behaviors by influencing a territory holder’s
 cooperative behavior. Overall, both our observational and experimental
 results suggest that reduced cooperative behavior is a cost of maintaining
 high levels of testosterone for territory-holding males.
description: Male courtship behavior was measured using video recordings and
 data were manually transcribed. Circulating testosterone was measured from
 blood samples collected males on the lek. Testosterone levels were
 manipulated using silastic implants sealed with silicon.

title: Data from: Why do zoos attract crows? A comparative study from Europe and Asia

description: Crows have successfully colonized many cities and urban zoos have been
 important in this process. To evaluate why zoos attract crows, we
 quantified crow numbers and behaviour in three zoos in Europe (Debrecen,
 Edinburgh, Vienna) and one in Asia (Sapporo). Data were collected in 445
 surveys over 297 days in summer 2014 and winter 2014-15. We found that
 crow numbers were highest in Vienna, intermediate in Debrecen and
 Edinburgh and lowest in Sapporo, increased significantly from summer to
 winter (Debrecen, Edinburgh, Vienna), and from mornings to afternoons
 (Debrecen, Sapporo, Vienna), and were higher in sunny weather than in
 cloudy weather with precipitation and when visitor numbers were low
 (Debrecen, Vienna). The crows’ use of natural food was highest in Vienna,
 intermediate in Edinburgh and Sapporo and low in Debrecen. The use of
 anthropogenic food was high in Debrecen and Sapporo, where the
 availability of open grassy areas typically used by crows for natural
 foraging was low. In Sapporo, food availability was more limited than in
 other zoos, resulting in strong territoriality and few crows in summer,
 which decreased further in winter. Our study indicates that crows are
 primarily attracted to zoos by food availability and secondarily by
 breeding opportunities and that the relative importance of natural vs.
 anthropogenic food sources may vary with zoo habitat structure. Our study
 draws attention to a previously overlooked role of zoos in urban
 biodiversity conservation. It may also provide useful information for the
 management of crow populations, if necessary, and for the planning of
 urban areas.

title: Murine polyomavirus DNA transitions through spatially distinct nuclear replication subdomains during infection

description: The replication of small DNA viruses requires both host DNA replication
 and repair factors that are often recruited to subnuclear domains termed
 viral replication centers (VRCs). Aside from serving as a spatial focus
 for viral replication, little is known about these dynamic areas in the
 nucleus. We investigated the organization and function of VRCs during
 murine polyomavirus (MuPyV) infection using 3D structured illumination
 microscopy (3D-SIM). We localized MuPyV replication center components,
 such as the viral large T-antigen (LT) and the cellular replication
 protein A (RPA), to spatially distinct subdomains within VRCs. We found
 that viral DNA (vDNA) trafficked sequentially through these subdomains
 post-synthesis, suggesting their distinct functional roles in vDNA
 processing. Additionally, we observed disruption of VRC organization and
 vDNA trafficking during mutant MuPyV infections or inhibition of DNA
 synthesis. These results reveal a dynamic organization of VRC components
 that coordinates virus replication.

title: Spectrum of cerebral arteriopathies in children with arterial ischaemic stroke

description: Objective: To determine that children with arterial ischaemic stroke due
 to an identifiable arteriopathy are distinct from those without
 arteriopathy, and that each arteriopathy subtype has unique and
 recognizable clinical features. Methods: We report a large, observational,
 multicenter cohort of children with AIS, age 1-month to 18-years, enrolled
 into the International Pediatric Stroke Study from 2003 to 2014. Clinical
 and demographic differences were compared using the Fisher exact test,
 with linear step-up permutation min-p adjustment for multiple comparisons.
 Exploratory analyses were conducted to evaluate differences between AIS
 cases with and without arteriopathy and between arteriopathy subtypes.
 Results: Of 2,127 children with AIS, 725 (34%) had arteriopathy (median
 age 7.45 years). Arteriopathy subtypes included: dissection (27%),
 moyamoya (24.5%), focal cerebral arteriopathy–inflammatory subtype (FCA-i,
 15%), diffuse cerebral vasculitis (15%), and non-specific arteriopathy
 (18.5%). Children with arteriopathic AIS were more likely to present
 between 6-9 years of age (p=0.029, OR 1.93), with headache (p=0.023, OR
 1.55), multiple infarctions (p&lt;0.001, OR 2.05), sickle cell anemia
 (p=0.007, OR 2.9), and head/neck trauma (p=0.018, OR 1.93). Antithrombotic
 usage and stroke recurrence were higher in children with arteriopathy.
 Among arteriopathy subtypes, patient with dissection were associated with
 male sex, older age, headache, and anticoagulant use; FCA-i with
 hemiparesis and single infarcts; moyamoya with seizures and recurrent
 strokes; and vasculitis with bilateral infarctions. Conclusion: Specific
 clinical profiles are associated with cerebral arteriopathies in children
 with AIS. These observations may be helpful indicators in guiding early
 diagnosis and defining subgroups that may benefit most from future
 therapeutic trials.

title: Clinical and radiologic features of pediatric opioid use‐associated neurotoxicity with cerebellar edema (POUNCE) syndrome

description: A 20-month-old boy weighing 15 kg underwent a successful surgery for
 hypospadias under general anesthesia. Before discharge, he was given a 2
 mg dose of oral morphine. His parents reportedly administered a 3 mg dose
 of oral morphine at home 2 hours later. Three hours later, he appeared
 drowsy and was put to bed. The next morning, approximately 14 hours later,
 he was not arousable and the ambulance was called. His oxygen saturation
 was at 94%, blood pressure at 90/60, and had decreased level of
 consciousness with poor respiratory effort. His blood venous gas showed pH
 = 6.91, PCO2 = 115 mm Hg, PO2 = 21 mm Hg, and
 bicarbonate of 22 mmol/L. He had pinpoint pupils and abnormal dystonic
 posturing. He was given naloxone 0.15 mg twice, 1 hour apart, with no
 effect, and he was then intubated.

title: Interrogating discordance resolves relationships in the rapid radiation of Old World fruit bats (Chiroptera: Pteropodidae)

description: The family Pteropodidae (Old World fruit bats) comprises &gt;200
 species distributed across the Old World tropics and subtropics. Most
 pteropodids feed on fruit, suggesting an early origin of frugivory,
 although several lineages have shifted to nectar-based diets. Pteropodids
 are of exceptional conservation concern with &gt;50% of species
 considered threatened, yet the systematics of this group has long been
 debated, with uncertainty surrounding early splits attributed to an
 ancient rapid diversification. Resolving the relationships among the main
 pteropodid lineages is essential if we are to fully understand their
 evolutionary distinctiveness, and the extent to which these bats have
 transitioned to nectar-feeding. Here we generated orthologous sequences
 for &gt;1400 nuclear protein-coding genes (2.8 million base-pairs)
 across 114 species from 43 genera of Old World fruit bats (57% and 96% of
 extant species- and genus-level diversity, respectively), and combined
 phylogenomic inference with filtering by information content to resolve
 systematic relationships among the major lineages. Concatenation and
 coalescent-based methods recovered three distinct backbone topologies that
 were not able to be reconciled by filtering via phylogenetic information
 content. Concordance analysis and gene genealogy interrogation shows that
 one topology is consistently the best supported, and that observed
 phylogenetic conflicts arise from both gene tree error and deep incomplete
 lineage sorting. In addition to resolving long-standing inconsistencies in
 the reported relationships among major lineages, we show that Old World
 fruit bats have likely undergone at least seven independent dietary
 transitions from frugivory to nectarivory. Finally, we use this phylogeny
 to identify and describe one new genus.

title: Data from: A survey of invasive plants on grassland soil microbial communities and ecosystem services

description: Invasive plants can cause changes in structure and function of the
 ecosystem undergoing invasion. Any changes in ecosystem diversity and
 community composition will likely alter ecosystem services provided by
 that ecosystem.  However, how these ecosystem services may change
 is poorly understood. To elucidate how these ecosystem services will
 change with invasion, we sampled 561 plots undergoing invasion by smooth
 brome (Bromus inermis) and four other invasive species at a native Rough
 Fescue prairie located near Saskatoon, Saskatchewan, Canada. Soil and
 plant surveys were undertaken weekly for 26 weeks beginning in May in 2014
 until November 2014, or the growing season. We measured a suite of
 ecosystem services, including greenhouse gasses, extracellular enzyme
 function, forage production, glyphosate degradation and decomposition.
 Furthermore, soil physical and chemical properties were measured, and soil
 bacterial and fungal communities were sequenced. This is a large and
 multifaceted dataset with complex temporal and spatial attributes that can
 be used to answer numerous questions regarding the functioning of prairie
 ecosystems and how invasive species will impact that
 functioning.

title: The evolution of reproductive isolation in Daphnia

description: Background The process by which populations evolve to become new species
 involves the emergence of various reproductive isolating barriers (RIB).
 Despite major advancements in understanding this complex process, very
 little is known about the order in which RIBs evolve or their relative
 contribution to the total restriction of gene flow during various stages
 of speciation. This is mainly due to the difficulties of studying
 reproductive isolation during the early stages of species formation. This
 study examines ecological and non-ecological RIB within and
 between Daphnia pulex and Daphnia
 pulicaria, two recently diverged species that inhabit distinct
 habitats and exhibit an unusual level of intraspecific genetic
 subdivision. Results We find that while ecological prezygotic barriers are
 close to completion, none of the non-ecological barriers can restrict gene
 flow between D. pulex and D.
 pulicaria completely when acting alone. Surprisingly, we also
 identified high levels of postzygotic reproductive isolation in
 ‘conspecific’ interpopulation crosses of D. pulex. Conclusions
 While the ecological prezygotic barriers are prevalent during the mature
 stages of speciation, non-ecological barriers likely dominated the early
 stages of speciation. This finding indicates the importance of studying
 the very early stages of speciation and suggests the contribution of
 postzygotic isolation in initiating the process of speciation.
