title: Data from: Olfaction at depth: cribriform plate size declines with dive depth and duration in aquatic arctoid carnivorans

description: It is widely accepted that obligate aquatic mammals, specifically toothed
 whales, rely relatively little on olfaction. There is less agreement about
 the importance of smell among aquatic mammals with residual ties to land,
 such as pinnipeds and sea otters. Field observations of marine carnivorans
 stress their keen use of smell while on land or pack ice. Yet, one
 dimension of olfactory ecology is often overlooked: while underwater,
 aquatic carnivorans forage “noseblind,” diving with nares closed, removed
 from air-borne chemical cues. For this reason, we predicted marine
 carnivorans would have reduced olfactory anatomy relative to
 closely-related terrestrial carnivorans. Moreover, because species that
 dive deeper and longer forage farther removed from surface scent cues, we
 predicted further reductions in their olfactory anatomy. To test these
 hypotheses, we looked to the cribriform plate (CP), a perforated bone in
 the posterior nasal chamber of mammals that serves as the only passageway
 for olfactory nerves crossing from the periphery to the olfactory bulb and
 thus covaries in size with relative olfactory innervation. Using CT scans
 and digital quantification, we compared CP morphology across Arctoidea, a
 carnivoran clade at the interface of terrestrial and aquatic ecologies. We
 found that aquatic species from two lineages that independently reinvaded
 marine environments (Pinnipedia, Mustelidae), have significantly smaller
 relative CP than terrestrials. Furthermore, within aquatic lineages,
 diving depth and duration were strongly correlated with CP loss, with the
 extreme-diving elephant seals showing the greatest reductions. These
 observations suggest that CP reduction in carnivorans is an adaptive
 response to shifting selection pressures associated with re-invasions of
 marine environments, particularly foraging at great depths. Because the CP
 is fairly well preserved in fossils, using methods presented here to
 quantify CP morphology in extinct mammals could help define evolutionary
 patterns of olfactory loss across lineages that have independently
 committed to life in water.

title: Breastfeeding dynamically changes endogenous oxytocin levels and emotion recognition in mothers

description: Breastfeeding behaviors can significantly change mothers’ physiological
 and psychological states. The hormone oxytocin may mediate breastfeeding
 and mothers’ emotion recognition. This study examined the effects of
 endogenous oxytocin fluctuation via breastfeeding on emotion recognition
 in 51 primiparous mothers. Saliva oxytocin was assessed before and after
 the manipulation (breastfeeding or holding an infant), and emotion
 recognition tasks were conducted. Among mothers who breastfed daily,
 mothers with more increased levels of oxytocin after breastfeeding showed
 greater reduced negative recognition and enhanced positive recognition of
 adult facial expressions. These oxytocin functions accompanying
 breastfeeding may support continued nurturing behaviors and also affect
 the general social cognition of other adults beyond any specific effect on
 infants.
description: We analyzed 51 primiparous mothers’ data. All participants
 continued breastfeeding their 2-to-9-month-old infants during the study
 period. None reported currently having any psychiatric disorders or taking
 any medication. After the informed consent, we provided a 15-minute
 get-acquainted period during which mothers did not touch their infants.
 Then we collected saliva samples, conducted a questionnaire about affect,
 and conducted two emotion recognition tasks twice, both before and after
 the manipulation. During the manipulation phase, participants either
 breastfed or held their infants for 15 minutes. We randomly assigned our
 participants to either of the two conditions (breastfeeding or holding)
 and informed them of the same in advance. Finally, the mothers completed
 all the remaining questionnaires. Since mothers conducted
 the experiment alone in the sound proof room, fathers and grandmothers of
 the infants also joined the experiment to care for the infants along with
 our research assistant.<br> All of the emotion recognition task
 performances were subtracted pre manipulation scores from post
 manipulation scores.

title: Urban forest fragments as a living laboratory for teaching botany: an example from Federal University of Rio Grande do Norte, Brazil

description: "Plant blindness" is affecting humans’ relationships
 with plants, which has negative consequences
 for both science and conservation. It
 is,therefore,important to find new ways to promote societal interest in
 botany and plants. One possibilityis encouraging the use of
 informal settings to promote curiosity and provide education to students.
 Forest fragments can be regarded as open air labs for teaching botany,
 especially on university campuses. We aimed to formally document the
 angiosperm diversity in the Mata dos Saguis(MS), a fragment of
 Atlantic forest under restoration belonging to the central campus of the
 Federal University of Rio Grande do Norte (UFRN), Brazil. We recorded 140
 species, 113 genera in 52 families and 24 orders of
 angiosperms. The MS has nearly10% of the species and one third of
 all the families occurring in the entire state of Rio Grande do Norte,
 representing the main evolutionary groups of the angiosperms and we also
 recorded two new species-occurrences for the state. Here we provide a
 checklist of the MS – a location that has been used as an open-air
 laboratory by many UFRN undergraduate courses in biosciences. We also
 share examples that can be replicated in other institutions and discuss
 the process of learning systematic botany
 in floristically-richcountries by means of alternative and
 hands-on experiences.

title: Data from: Optimization of nitrogen and carbon removal with simultaneous partial nitrification, anammox, and denitrification (SNAD) in membrane bioreactor (MBR)

description: In this study, a membrane bioreactor (MBR) was used to achieve both
 nitrogen and carbon removal by a simultaneous partial nitrification,
 anammox, and denitrification (SNAD) process. During the entire
 experiment, the optimal operating parameters as determined by response
 surface methodology (RSM) were a C/N value of 1.16, a DO value of 0.84
 mg·L-1, and an aerobic time (Tae) of 15.75 min. Under these conditions,
 the SNAD process achieved efficient and stable nitrogen and carbon
 removal; the total inorganic nitrogen (TIN) removal efficiency and
 chemical oxygen demand (COD) removal efficiency were 92.31% and 95.67%,
 respectively. With the formation of granular sludge, the membrane fouling
 rate (MFR) decreased significantly from 35.0 Pa·h-1 at SNAD
 start-up to 19.9 Pa·h-1 during stable operation. Fluorescence in
 situ hybrid (FISH) analyse confirmed the structural characteristics and
 the relative ratio of AerAOB, AnAOB, and DNB in the SNAD system.

title: Characterization of platinum(II) complexes exhibiting inhibitory activity against 20S Proteasome

description: Proteasome inhibitors are useful for biochemical research and clinical
 treatment. In our previous study, we reported that the 4N-coordinated
 platinum complexes with anthracene and heterocycle exhibited proteasome
 inhibitory activity. In the present study, the structure-activity
 relationships and characterization of these complexes were determined for
 elucidation of role of aromatic ligands. Lineweaver-Burk analysis revealed
 that the chemical structure of heterocyles affects binding mode of
 platinum complexes. Platinum complexes with anthracene and pyridine showed
 competitive inhibition although platinum complexes with antharcene and
 phenantholine showed non-competitive inhibition. The structure-activity
 relationships demonstrated that anthracene moiety play a crucial role for
 proteasome inhibitory activity. The platinum complexes with naphthalene or
 benzene exhibited lower inhibitory activities than the platinum complex
 with anthracene. The reactivity with N-acetyl cysteine varied according to
 the chemical structure of complexes.

title: Enhancement of microwave absorption bandwidth of MXene nanocomposites through macroscopic design

description: MXene, the new family of 2D materials having numerous nanoscale layers, is
 being considered as a novel microwave absorption material. 
 However, MXene/functionalized MXene loaded polymer nanocomposites exhibit
 narrow reflection loss (RL) bandwidth (RL ≤ -10 dB).  In order to
 enhance the microwave absorption bandwidth of MXene hybrid-matrix
 materials, for the first time, macroscopic design approach is carried out
 for TiO2-Ti3C2Tx MXene and Fe3O4@TiO2-Ti3C2Tx MXene hybrids through
 simulation.  The simulated results indicate that use of pyramidal
 meta structure of MXene can significantly tune the RL bandwidth. 
 For optimized MXene hybrid-matrix materials pyramid pattern, the bandwidth
 enhances to 3-18 GHz.  Experimental RL value well matched with
 the simulated RL.  On the other hand, for optimized
 Fe3O4@TiO2-Ti3C2Tx hybrid exhibits two specific absorption bandwidths viz.
 3-18 GHz (minimum RL value - 47 dB).  Compared to other 2D
 nanocomposites such as graphene or Fe3O4-graphene, MXene hybrid-matrix
 materials shows better microwave absorption bandwidth in macroscopic
 pattern. 
description: Samples
 used for EM parameter measurement were prepared by mixing the
 TiO<sub>2</sub>-Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> and Fe<sub>3</sub>O<sub>4</sub>@TiO<sub>2</sub>-Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> powders with paraffin with a mass content of 70%.  In a typical composite preparation, powders and paraffin were well mixed at 80±2 ºC mechanically to avoid aggregation.  After 5 min, the viscous mixtures were casted on the respective Teflon molds. Conducting Aluminum tape was pasted at the bottom of the fabricated structure as a perfect electric conductor (PEC).  Schematically, fabrication process of both the meta structure i.e., pyramidal and multi-layered pyramidal structure was shown in Figure S1 and Figure S2 respectively.  Reflection loss (<i>S</i>-parameters) were measured inside anechoic chamber by using an Agilent PNA N523A vector network analyzer using two horn antenna.  In the measurement set-up, a pair of horn antenna was used as a transmitter to send off the electromagnetic wave onto the composite sample, whereas the other antenna was used to receive the reflection from the sample.  All the horn antennas were connected to the vector network analyzer (VNA) during the entire measurements.  The entire broadband absorption measurement technique was shown schematically in <b>Figure S3.</b>

title: Community-level interactions between plants and soil biota during range expansion

description: 1. Plant species that expand their range in response to current climate
 change will encounter soil communities that may hinder, allow, or even
 facilitate plant performance. It has been shown repeatedly for plant
 species originating from other continents that these plants are less
 hampered by soil communities from the new than from the original range.
 However, information about the interactions between intra-continental
 range expanders and soil communities is sparse, especially at community
 level. 2. Here we used a plant-soil feedback experiment approach to
 examine if the interactions between range expanders and soil communities
 change during range expansion. We grew communities of range-expanding and
 native plant species with soil communities originating from the original
 and new range of range expanders. We determined the composition of fungi,
 bacteria and nematodes in these conditioned soils by high-throughput
 amplicon sequencing of the ITS region and the 16S rRNA gene and using
 morphological methods, respectively. Then we tested how these soil
 communities influence the growth of subsequent communities of range
 expanders and natives. 3. We found that after the conditioning phase soil
 bacterial, fungal and nematode communities differed by origin and by
 conditioning plant communities. Despite differences in bacterial, fungal
 and nematode communities between original and new range, soil origin did
 not influence the biomass production of plant communities. Both native and
 range expanding plant communities produced most aboveground biomass in
 soils that were conditioned by plant communities distantly related to
 them. 4. Synthesis. We conclude that communities of range-expanding plant
 species shape specific soil communities in both original and new range
 soil. Plant-soil interactions of range expanders in communities can be
 similar to the ones of their closely related native plant species.

title: Data from: Sex differences in CSF biomarkers vary by Alzheimer’s disease stage and APOE epsilon 4 genotype

description: Objective:  To evaluate sex-differences in cerebrospinal fluid
 (CSF) biomarkers, taking the potential modifying role of clinical disease
 stage and APOEe4 genotype into account. Method: We included participants
 (n=1801) with probable AD dementia (n=937), Mild Cognitive Impairment
 (MCI; n=437) and Subjective Cognitive Decline (SCD; n=427). Main outcomes
 were CSF amyloid β1-42 (Aβ42), total tau (Tau) and tau phosphorylated at
 threonine 181 (pTau) levels. Age corrected three-way interactions between
 sex, disease stage (i.e. syndrome diagnosis at baseline) and APOEe4 were
 tested with linear regression analyses for each outcome measure. In case
 of significant interactions (p&lt;0.05), sex-differences were further
 evaluated by stratifying analyses for clinical disease stage and APOEe4
 genotype including age as a covariate. Results: Three-way interactions
 were significant for Tau (p&lt;0.001) and pTau (p&lt;0.01), but
 not Aβ42. In APOE carriers, women showed higher (p)Tau concentrations than
 men in SCD (Cohens d (95%CI): Tau= 0.52 (0.19-0.84), p&lt;.001;
 pTau=0.44 (0.11-0.77),p=.004 ) and MCI (Cohens d (95%CI): Tau= 0.54
 (0.28-0.80), p&lt;.001; pTau=0.52 (0.26-0.77), p&lt;.001), but not
 in AD dementia. In APOE non-carriers, women showed higher (p)Tau
 concentrations in MCI (Cohens d (95%CI): Tau= 0.49 (0.17-0.80), p=.002;
 pTau=0.47 (0.16-0.78), p=.003) and AD dementia (Cohens d (95%CI): Tau=
 0.42 (0.19-0.65), p&lt;.001; pTau=0.38 (0.15-0.61), p=.002), but not
 in SCD. Conclusions: Within APOEe4 carriers, sex-differences in CSF (p)Tau
 are more evident in early disease stages, whereas for APOEe4 non carriers
 sex-differences are more evident in advanced disease stages. These
 findings suggest that the effect of APOE e4 on sex-differences in CSF
 biomarkers depends on disease stage in AD.

title: Successional habitat filtering of rainforest trees is explained by potential growth more than by functional traits

description: Species along successional gradients differ in functional traits, which
 may function as environmental filters and also explain differences in
 growth rates. Alternatively, species might be filtered by growth rates and
 these are explained by differences in other traits. We explored the
 relationships between leaf and wood traits, growth and successional
 habitat, and asked if growth is related to habitat because both are driven
 by a similar set of traits or if growth is the main trait explaining
 habitat and relationships with other traits are indirect. Tropical trees
 are often classified as second-growth (SG) or old-growth (OG) specialists,
 and generalists. Since succession is a continuous process and lumping
 species into three groups may not do justice to gradual differences, we
 tested if a continuous variable based on relative tree abundance in OG and
 SG forests might be a better predictor than classifying trees’ habitat
 preferences into categories. We measured height growth of 47 trees species
 planted in a reforestation trial in Costa Rica and evaluated
 size-standardized potential growth during the first years when there was
 little shading among trees. Growth and habitat were related to wood
 density (WD), theoretical hydraulic conductivity (Kh), specific leaf area
 (SLA), leaf dry matter content (LDMC) and leaf nitrogen content (N).
 Potential growth rates and Kh were significantly correlated with habitat
 measured on a continuous scale, while growth and LDMC differed among the
 three groups of habitat specialization. Growth was also correlated with WD
 and Kh. Habitat specialization was correlated with the first principal
 component of the functional traits space. However, structural equation
 models suggest that the relationship with leaf and wood traits is mostly
 indirect and potential growth is the most important trait directly related
 to environmental filtering along a successional gradient. In our dataset,
 classifiying the successional status of species using the proportion of
 records from OG forests explains traits about as well as a classification
 into three groups, but provides more information about the species’
 position along the successional gradient.
description: Tree height was measured to calculate height growth and height
 growth at 1m was modelled as described in the paper. Functional traits
 (branch wood density, theoretical hydraulic conductivity, specific leaf
 area, leaf dry matter content and leaf nitrogen per dry weight) are

title: Data from: Comparative transcriptomics reveals domestication-associated features of Atlantic salmon lipid metabolism

description: Domestication of animals imposes strong targeted selection for desired
 traits but can also result in unintended selection due to new domestic
 environments. Atlantic salmon was domesticated in the 1970s and has
 subsequently been selected for faster growth in systematic breeding
 programmes. More recently, salmon aquaculture has replaced fish oils (FO)
 with vegetable oils (VO) in feed, radically changing the levels of
 essential long-chain polyunsaturated fatty acids (LC-PUFA). Our aim was to
 study the impact of domestication on metabolism and explore the hypothesis
 that the shift to VO-diets has unintentionally selected for a
 domestication-specific lipid metabolism. We conducted a 96-day feeding
 trial of domesticated and wild salmon fed diets based on FO, VO or
 phospholipids (PL), and compared transcriptomes and fatty acids in tissues
 involved in lipid absorption (pyloric caeca) and lipid turnover and
 synthesis (liver). Domesticated salmon had faster growth and higher gene
 expression in glucose and lipid metabolism compared to wild fish, possibly
 linked to differences in regulation of circadian rhythm pathways. Only the
 domesticated salmon increased expression of LC-PUFA synthesis genes when
 given VO. This transcriptome response difference was mirrored at the
 physiological level, with domesticated salmon having higher LC-PUFA but
 lower 18:3n-3 and 18:2n-6 levels. In line with this, the VO diet decreased
 growth rate in wild but not domesticated salmon. Our study revealed a
 clear impact of domestication on transcriptomic regulation linked to
 metabolism and suggests that unintentional selection in the
 domestic-environment has resulted in evolution of stronger compensatory
 mechanisms to a diet low in LC-PUFA.

title: Data from: Parasitoids as drivers of symbiont diversity in an insect host

description: Immune systems have repeatedly diversified in response to parasite
 diversity. Many animals have outsourced part of their immune defence to
 defensive symbionts, which should be affected by similar evolutionary
 pressures as the host’s own immune system. Protective symbionts provide
 efficient and specific protection and respond to changing selection
 pressure by parasites. Here, we use the aphid Aphis fabae, its protective
 symbiont Hamiltonella defensa and its parasitoid Lysiphlebus fabarum to
 test whether parasite diversity can maintain diversity in protective
 symbionts. We exposed aphid populations with the same initial symbiont
 composition to parasitoid populations that differed in their diversity. As
 expected, single parasitoid genotypes mostly favoured a single symbiont
 that was most protective against that particular parasitoid, while
 multiple symbionts persisted in aphids exposed to more diverse parasitoid
 populations, which in turn affected aphid population density and rates of
 parasitism. Parasite diversity may be crucial to maintaining symbiont
 diversity in nature.
