title: Data from: Electrical imaging of cortical and spinal axons using high-density microelectrode arrays

description: Mammalian axons are specialized for transmitting action potentials to
 targets within the central and peripheral nervous system. A growing body
 of evidence suggests that, besides signal conduction, axons play essential
 roles in neural information processing, and their malfunctions are common
 hallmarks of neurodegenerative diseases. The technologies available to
 study axonal function and structure integrally limit the comprehension of
 axon neurobiology.  Complementary-metal-oxide-semiconductor
 (CMOS) -based high-density microelectrode arrays (HD-MEAs) have been
 designed to record extracellular action potentials from neuronal cultures
 and allow tracking axonal signals across hundreds of microelectrodes.
 Thanks to a low-noise CMOS-design, HD-MEAs enable detection of APs across
 entire arbors of cortical axons. HD-MEAs provide noninvasive access to
 axonal action potentials and impose no constraints on the duration of the
 recording sessions. Here we present extracellular electrical activity
 recorded from rat's primary neurons using CMOS-based HD-MEA system
 (MaxWell Biosystems AG). Datasets comprise electrophysiological recordings
 obtained from primary motor and cortical neurons. Recorded signals were
 up-sampled to 200 kHz following the Whitaker-Shannon interpolation
 formula. Recorded signals were spike-sorted and spike-trigger averaged
 across an entire array (26400 electrodes). Such signal representation is
 referred to as ‘axonal electrical image’. 
description: Array-wide averaging of voltage traces, synchronized with the
 initial trace (recorded from the axon initial segment), reveals the
 spatiotemporal distribution of extracellular action potentials across an
 entire axonal arbor. The first step in obtaining these data was selecting
 9 electrodes that were closest to the putative axon initial segment. We
 next designed multiple recording configurations covering the entire array
 - in each configuration, 9 of the 1024 readout channels were routed to the
 9 preselected electrodes, and remaining available channels were routed to
 randomly selected electrodes. Each configuration was used to sample
 neuronal activity during 2 minutes. Signals recorded by the 9 preselected
 electrodes in each configuration were sorted using the Spyking-Circus
 algorithm (1). Timestamps of the sorted signals were used to trigger the
 averaging of voltage traces recorded across all other electrodes in the
 array. The spatiotemporal distribution of averaged signals was
 reconstructed using a custom-designed Matlab code. 1.

title: Sponge presence increases the diversity and abundance of fish and invertebrates in a subtropical seagrass bed

description: Ecosystem engineers (e.g., seagrasses) can have profound effects on
 biodiversity and community structure. Sponges possess many traits (e.g.,
 create complex structure) that suggest they may act as ecosystem
 engineers, but we know little about their relationships with the animal
 communities that inhabit seagrass beds. This study explored the effects of
 the marine sponge, Ircinia felix, on fish and invertebrate taxa richness,
 abundance, turnover, and community composition in a seagrass bed through a
 1-year field experiment performed in The Bahamas. We recorded the fish and
 invertebrate communities present in 5 × 5 m plots with the addition of
 either a live sponge, a polypropylene sponge replica (structure), or no
 additional structure (control). Both taxonomic groups responded similarly
 to the addition of a live sponge. Taxa richness and abundance increased at
 least 4-fold over a year in the presence of I. felix but decreased 2-fold
 or more in the other plot types. Live sponge presence increased the number
 of new taxa gained by at least 24% and reduced the number of taxa lost
 compared to other plot types. Finally, we found that the fish community
 shifted in a more consistent direction in the presence of a live sponge
 than in the other plots. Our study shows that sponges can act as ecosystem
 engineers in subtropical seagrass systems; however, additional research is
 needed to determine the full extent and implications of their ecological
 effects.

title: Seasonal ecosystem linkages contribute to the maintenance of migratory polymorphism in a salmonid population

description: The influence of resource subsidies on animal growth, survival, and
 reproduction is well understood, but their ultimate effects on life
 history have been less explored. Some wild species have a partially
 migratory life history, wherein migration is dictated based upon threshold
 traits regulated in part by the seasonal availability of resources. We
 conducted a large-scale field manipulation experiment where we provided a
 terrestrial invertebrate subsidy to red-spotted masu salmon. Individuals
 in stream reaches that received a subsidy had, on average, a 53% increase
 in growth rate relative to those in control reaches. This increased growth
 resulted in a greater proportion of individuals reaching the threshold
 body size and smolting in the autumn. Consequently, 19–55% of females in
 subsidized reaches became migratory, whereas 0–14% became migratory in the
 control reaches. Our findings highlight seasonal ecosystem linkage as a
 key ecosystem property for maintaining migratory polymorphism in partially
 migratory animals.

title: Distinct responses and range shifts of lizards populations across an elevational gradient under climate change

description: Ongoing climate change has profoundly affected global biodiversity, but
 its impacts on populations across elevations remain
 understudied. Using a mechanistic niche model incorporating
 species traits, we predicted ecophysiological responses (activity times,
 oxygen consumption and evaporative water loss) for lizard populations at
 high-elevation (&lt; 3600 m asl) and extra-high-elevation (&gt;
 3600 m asl) under recent (1970–2000) and future (2081–2100) climates.
 Compared with their high-elevation counterparts, lizards from
 extra-high-elevations are predicted to experience a greater increase in
 activity time and oxygen consumption but a similar increase in evaporative
 water loss. By integrating these ecophysiological traits into a hybrid
 species distribution model (HSDM), we were able to make the following
 predictions under two warming scenarios (SSP1-2.6, SSP5-8.5). By
 2081–2100, we predict that lizards at both high- and extra-high-elevations
 will shift upslope; lizards at extra-high-elevations will gain more and
 lose less habitat than will their high-elevation congeners. We therefore
 advocate the conservation of high-elevation species in the context of
 climate change, especially for those populations living close to their
 lower elevational range limits. In addition, by comparing the results
 from HSDM and traditional species distribution models, we
 highlight the importance of considering intraspecific variation
 and local adaptation in physiological traits along elevational gradients
 when forecasting species' future distributions under climate
 change.

title: Data for: Environmental gradualism explains variation in pollination systems of columnar cacti: Phylogenetic and trait evolution analyses

description: Aim: The Geographic Dichotomy Hypothesis (GDH) states several flowering
 plant groups have specialized pollination systems in tropical areas, where
 resources are more reliable and pollinator communities tend to be more
 stable. Our main goal was to understand the scope of the GDH and/or
 gradual environmental variation considering the evolutionary history of
 the pollination traits. Location: Neotropical tropics and adjacent
 extra-tropics. Major taxa studied: Columnar cacti. Methods: Using a
 database composed of ~54 columnar cacti species (31.7% of the global
 columnar cactus species), four complex traits were analyzed: pollination
 syndromes, reproductive systems, type of anthesis, and duration of
 anthesis. We applied GLMs, phylogenetic regressions, evolutionary trait
 optimization, and multivariate models with 19 bioclimatic variables and
 potential evapotranspiration. Results: Weak phylogenetic signal was
 detected for all traits, giving consistent results between GLMs and
 phylogenetic regression analysis. The pollination syndrome and duration of
 anthesis varied with latitude, in contrast to the reproductive system and
 the type of anthesis. In the Southern Hemisphere, the pollinators were
 more diverse and the duration of anthesis was longer. Different
 evolutionary paths between hemispheres were detected and optimization
 showed a complex pattern in the evolution of traits, suggesting high
 homoplasy with multiple transformations by convergence and/or parallelism.
 The environmental models showed thermic seasonality may be at the core of
 the latitudinal variation of the pollination system. Main conclusions: We
 did not detect a geographical dichotomy in pollination systems of the
 cacti, but rather a gradual change in different pollination attributes.
 Therefore, instead of a GDH, we propose an environmental gradient
 hypothesis (EGH). Environmental variables may be explaining the variation
 detected in pollination system traits by conditioning floral properties
 (morphology, phenology), diversity and distribution of pollinators, and/or
 coevolution occurrence. The complexity implied in these traits is
 consistent with high homoplasy levels and a differential evolutionary
 history between the hemispheres.

title: Methane and carbon dioxide cumulative amounts data for: Algal amendment enhances biogenic methane production from coals of different thermal maturity

description: The addition of small amounts of algal biomass to stimulate methane
 production in coal seams is a promising low carbon renewable coalbed
 methane enhancement technique. However, little is known about how the
 addition of algal biomass amendment affects methane production from coals
 of different thermal maturity. Here, we show that biogenic methane can be
 produced from five coals ranging in rank from lignite to low-volatile
 bituminous using a coal-derived microbial consortium in batch microcosms
 with and without algal amendment. The addition of 0.1 g/L algal biomass
 resulted in maximum methane production rates up to 37 days earlier and
 decreased the time required to reach maximum methane production by 17–19
 days when compared to unamended, analogous microcosms. Cumulative methane
 production and methane production rate were generally highest in low rank,
 subbituminous coals, but no clear association between increasing vitrinite
 reflectance and decreasing methane production could be determined.
 Microbial community analysis revealed that archaeal populations were
 correlated with methane production rate (p=0.01), vitrinite reflectance
 (p=0.03), percent volatile matter (p=0.03), and fixed carbon (p=0.02), all
 of which are related to coal rank and composition. Sequences indicative of
 the acetoclastic methanogenic genus Methanosaeta dominated low rank coal
 microcosms. Amended treatments that had increased methane production
 relative to unamended analogs had high relative abundances of the
 hydrogenotrophic methanogenic genus Methanobacterium and the bacterial
 family Pseudomonadaceae. These results suggest that algal amendment may
 shift coal-derived microbial communities towards coal-degrading bacteria
 and CO2-reducing methanogens. These results have broad implications for
 understanding subsurface carbon cycling in coal beds and the adoption of
 low carbon renewable microbially enhanced coalbed methane techniques
 across a diverse range of coal geology.

title: Dataset: The dispersal of microbes among and within flowers by butterflies

description: This data set was collected to examine the ability of Lepidoptera to
 transport microbes among flowers, while foraging. The first set,
 "experiment 1", records bacteria and yeasts carried by two
 species of generalist-nectar-feeding butterflies, Speyeria mormonia and
 Glaucopsyche lygdamus. We captured wild butterflies in the central
 Colorado Rockies. We recorded butterfly species, sex, wing wear (which
 measures age, from 1 = youngest to 5 = oldest), date caught, date tested,
 and the number of colonies on a YM plate that was streaked by the
 proboscis, or by a wash from the thorax or by allowing the butterfly to
 walk across the plate. The second data set, "experiment 2",
 records the number of colonies of a test bacteria, Rhodococcus fascians,
 on stigma, anthers and nectaries of Pyrrocoma crocea. Data were collected
 using flowerheads and adult Speyeria mormonia collected in the field. A
 butterfly was allowed to feed on a floret; the floret was immediately
 dissected, and the stigma, anthers and nectaries streaked on a YM plate. A
 floret on a second flowerhead was then innoculated with the bacteria. The
 butterfly was allowed to feed on the innoculated floret, and the floret
 was immediately dissected and parts streaked as for the training floret.
 The butterfly then fed on a floret in the first flowerhead, and that
 floret was immediately dissected and parts streaked as for other
 florets.  Data include the identity, sex and wing wear of the
 butterfly, the date captured, the date the experiment was run, the number
 of colonies of R. fascians from stigma, anthers and nectaries of all three
 floret types.

title: Data from: Robustness of Felsenstein’s versus transfer bootstrap supports with respect to taxon sampling

description: The bootstrap method is based on resampling sequence alignments and
 re-estimating trees. Felsenstein’s bootstrap proportions (FBP) is the most
 common approach to assess the reliability and robustness of sequence-based
 phylogenies. However, when increasing taxon sampling (i.e., the number of
 sequences) to hundreds or thousands of taxa, FBP tends to return low
 supports for deep branches. The Transfer Bootstrap Expectation (TBE) has
 been recently suggested as an alternative to FBP. TBE is measured using a
 continuous transfer index in [0,1] for each bootstrap tree, instead of the
 binary {0,1} index used in FBP to measure the presence/absence of the
 branch of interest. TBE has been shown to yield higher and more
 informative supports, while inducing a very low number of falsely
 supported branches. Nonetheless, it has been argued that TBE must be used
 with care due to sampling issues, especially in datasets with high number
 of closely related taxa. In this study, we conduct multiple experiments by
 varying taxon sampling and comparing FBP and TBE support values on
 different phylogenetic depth, using empirical datasets. Our results show
 that the main critique of TBE stands in extreme cases with shallow
 branches and highly unbalanced sampling among clades, but that TBE is
 still robust in most cases, while FBP is inescapably negatively impacted
 by high taxon sampling. We suggest guidelines and good practices in TBE
 (and FBP) computing and interpretation.

title: Dataset for: Temperature sensitivity of carbon concentrating mechanisms in the diatom Phaeodactylum tricornutum

description: Marine diatoms are key primary producers across diverse habitats in the
 global ocean. Diatoms rely on a biophysical carbon concentrating mechanism
 (CCM) to supply high concentrations of CO2 around their carboxylating
 enzyme, RuBisCO. The necessity and energetic cost of the CCM are likely to
 be highly sensitive to temperature, as temperature impacts CO2
 concentration, diffusivity, and the kinetics of CCM components. Here, we
 used membrane inlet mass spectrometry (MIMS) and modeling to capture
 temperature regulation of the CCM in the diatom Phaeodactylum tricornutum
 (Pt). We found that enhanced carbon fixation rates by Pt at elevated
 temperatures were accompanied by increased CCM activity capable of
 maintaining RuBisCO close to CO2 saturation but that the mechanism varied.
 At 10 and 18 °C, diffusion of CO2 into the cell, driven by Pt’s
 ‘chloroplast pump’ was the major inorganic carbon source. However, at 18
 °C, upregulation of the chloroplast pump enhanced (while retaining the
 proportion of) both diffusive CO2 and active HCO3- uptake into the
 cytosol, and significantly increased chloroplast HCO3- concentrations. In
 contrast, at 25 °C, compared to 18 °C, the chloroplast pump had only a
 slight increase in activity. While diffusive uptake of CO2 into the cell
 remained constant, active HCO3- uptake across the cell membrane increased
 resulting in Pt depending equally on both CO2 and HCO3- as inorganic
 carbon sources. Despite changes in the CCM, the overall rate of active
 carbon transport remained double that of carbon fixation across all
 temperatures tested. The implication of the energetic cost of the Pt CCM
 in response to increasing temperatures was discussed.
