title: Data from: Is repeatability of metabolic rate influenced by social separation? a test with a teleost fish

description: Metabolic rates are typically thought to have important influences on
 fitness and more broadly be relevant to the ecology and evolution of
 animals. Previous studies demonstrate that metabolic rates are repeatable
 to a certain extent under constant conditions, but how social conditions
 influence the repeatability of metabolic rate remains largely unknown. In
 this study we investigated the repeatability of resting metabolic rate
 (RMR) in the highly-social crucian carp (Carassius auratus) after being
 socially separated for different time periods relative to control fish
 that were not socially separated. We found that RMR was repeatable in fish
 in the control group, while the repeatability of RMR disappeared quickly
 (even within 7 d) when fish were exposed to social separation. This study
 is the first to examine the role of social separation at different time
 periods on the repeatability of intra-individual physiological variation
 in fish. We highlight that inter-individual repeatability of metabolic
 rate can be substantial over time but was eliminated by social separation.
 The findings indicate that the repeatability of metabolic rate in fish is
 condition-dependent, and that the change in repeatability of metabolic
 rate should not be overlooked when considering the ecological and
 evolutionary effects of environmental change.

title: Rapid and repeated divergence of animal chemical signals in an island introduction experiment

description: Studies of animal communication have documented myriad rapid,
 context-dependent changes in visual and acoustic signal design. In
 contrast, relatively little is known about the capacity of vertebrate
 chemical signals to rapidly respond, either plastically or
 deterministically, to changes in context. Four years following an
 experimental introduction of lizards to replicate experimental islets, we
 aimed to determine if chemical signal design of the experimental
 populations differed from that of the source population. In 2014, we
 translocated Podarcis erhardii lizards from a large,
 predator-rich island to each of five replicate predator-free islets. Mean
 population densities increased five-fold over the following four years and
 bite scars suggest significantly more intraspecific fighting among these
 experimental populations. In 2018 we analyzed the chemical signal design
 of males in each of the experimental populations and compared it to the
 chemical signals of the source population. We found that males
 consistently presented a significantly more complex chemical signal
 compared to the source population. Moreover, their chemical signals were
 marked by high proportions of octadecanoic acid, oleic acid, and
 α-tocopherol, three compounds that are known to be associated with lizard
 territoriality and mate choice. Our island introduction experiment thus
 suggests that the chemical signal design of animals can shift rapidly and
 predictably in novel ecological contexts.

 Mavronissi (population 5), and Petalida (population 6). The relative
 amount of each component was determined as the percent of the total ion
 current (TIC) and reported for each individual. The specific names of the

title: Repeated fire shifts carbon and nitrogen cycling by changing plant inputs and soil decomposition across ecosystems

description: Fires shape the biogeochemistry and functioning of many ecosystems, and
 fire frequencies are changing across much of the globe. Frequent fires can
 change soil carbon (C) and nitrogen (N) storage by altering the quantity
 and chemistry of plant inputs through changes in plant biomass and
 composition as well as altering decomposition of soil organic matter. How
 decomposition rates change with shifting inputs remains uncertain because
 most studies focus on the effects of single fires, where transient changes
 may not reflect responses to decadal changes in burning frequencies. Here,
 we sampled seven sites exposed to different fire frequencies. In four of
 the sites, we intensively sampled both soils and plant communities across
 four ecosystems in North America and Africa spanning tropical savanna,
 temperate coniferous savanna, temperate broadleaf savanna, and temperate
 coniferous forest ecosystems. Each site contained multiple plots burned
 frequently for 33-61 years and nearby plots that had remained unburned
 over the same period replicated at the landscape scale. Across all sites,
 repeatedly burned plots had 25-185% lower bulk soil C and N concentrations
 but also 2-10-fold lower potential decomposition of organic matter
 compared to unburned sites. Soil C and N concentrations and extracellular
 enzyme activities declined with frequent fire because fire reduced both
 plant biomass inputs into soils and dampened the localized enrichment
 effect of tree canopies. Examination of soil extracellular enzyme
 activities revealed that fire decreased the potential turnover of organic
 matter in the forms of cellulose, starch, and chitin (p&lt;0.0001) but
 not polyphenol and lignin (p=0.09), suggesting a shift in soil C and N
 cycling. Inclusion of δ13C data from three additional savanna sites (19-60
 years of altered fire frequencies) showed that soil C losses were largest
 in sites where estimated tree inputs into soils declined the most
 (r2=0.91, p&lt;0.01). In conclusion, repeated burning reduced C and N
 storage, consistent with previous studies, but fire also reduced potential
 decomposition, likely contributing to slower C and N cycling. Trees were
 important in shaping soil carbon responses across sites, but the magnitude
 of tree effects differed and depended on how tree biomass inputs into soil
 responded to fire.

title: Examining the link between relaxed predation and bird colouration on islands

description: Insular ecosystems share analogous ecological conditions, leading to
 patterns of convergent evolution that are collectively termed the “island
 syndrome”. In birds, part of this syndrome is a tendency for a duller
 plumage, possibly as a result of relaxed sexual selection and the reduced
 need for species recognition. Despite this global pattern, some insular
 species display a more colourful plumage than their mainland relatives,
 but why this occurs has remained unexplained. Here, we examine the
 hypothesis that these cases of increased plumage colouration on islands
 could arise through a relaxation of predation pressure. We used
 comparative analyses to investigate whether average insular richness of
 raptors of suitable mass influences the plumage colourfulness and
 brightness across 110 pairs of insular endemic species and their closest
 mainland relatives. As predicted, we find a likely negative relationship
 between insular colouration and insular predation whilst controlling for
 mainland predation and colouration, so that species were more likely to
 become more colourful as the number of insular predators decreased. In
 contrast, plumage brightness was not influenced by predation pressure.
 Relaxation from predation, together with drift, might thus be a key
 mechanism of species phenotypic responses to insularity.

title: Enhanced stromal H2S production via CBS upregulation promotes estrogen-stimulated human endometrial angiogenesis

description: Angiogenesis is a physiological process for endometrial regeneration in
 the menstrual cycle and remodeling during pregnancy. Endogenous hydrogen
 sulfide (H2S), produced by cystathionine-β synthase (CBS) and
 cystathionine-γ lyase (CSE), is a potent proangiogenic factor; yet,
 whether the H2S system is expressed in the endometrium and whether H2S
 plays a role in endometrial angiogenesis are unknown.  This study
 was to test whether estrogens stimulate endometrial H2S biosynthesis to
 promote endometrial microvascular endothelial cell (EMEC)
 angiogenesis.  CBS mRNA/protein and H2S production significantly
 differed among endometria from postmenopausal (POM), premenopausal
 secretory (sPRM) and proliferative (pPRM) nonpregnant (NP) and pregnant
 (Preg) women (p&lt;0.05) in a rank order of POM ≈ sPRM &lt; pPRM
 &lt;&lt;&lt; Preg, positively correlating with angiogenesis
 indices and endogenous estrogens and with no difference in CSE
 expression.  CBS and CSE proteins were localized to stroma,
 glands, and vessels in endometrium, and greater stromal CBS protein was
 observed in the pPRM and Preg states.  Estradiol (but not
 progesterone) stimulated CBS (but not CSE) expression and H2S production
 in endometrial stromal cells (ESCs) in vitro, which were attenuated by ICI
 182,780.  The H2S donor sodium hydrosulfide promoted in vitro
 endometrial microvascular endothelial cell (EMEC) angiogenesis. 
 Co-culture with sPRM, pPRM, and Preg ESCs all stimulated EMEC migration
 with a rank order of sPRM &lt; pPRM ≈ Preg.  CBS (but not
 CSE) inhibition attenuated ESC-stimulated EMEC migration.
  Estradiol did not affect EMEC migration but potentiated
 ESC-stimulated EMEC migration.  Altogether, estradiol-stimulated
 specific receptor-dependent stromal CBS-H2S production to promote
 endometrial EMEC angiogenesis in women.

title: Northern elephant seal UAS mass estimates

description: Unmanned aerial system (UAS) photogrammetry offers a method that is safer
 for both animals and researchers and is logistically simpler than
 traditional weighing methods (Fiori et al. 2017). Additionally, UAS
 photogrammetry facilitates larger sample sizes because it allows
 measurement at larger spatial scales, thereby increasing statistical power
 (Sweeney et al. 2015). However, UAS photogrammetry requires calibration
 and validation prior to use in order to assess the error relative to known
 mass measurements. Species-specific calibration of appropriate metrics
 (e.g., footprint area (Christiansen et al. 2016)) is necessary to account
 for body shape differences (e.g., “peanut head” syndrome) (Miller et al.
 2012, Joblon et al. 2014). Further, the accuracies of photographs taken in
 overhead and oblique positions are rarely compared due to the challenge of
 weighing and repeatedly photographing uniquely identified individuals
 (Fearnbach et al. 2018). Northern elephant seals (Mirounga angustirostris)
 offer a unique opportunity to calibrate UAS photogrammetry to measure body
 mass. Elephant seals undergo dramatic changes in mass throughout the year
 and consistently haul-out to breed and molt at Año Nuevo Natural Reserve,
 California, USA (37.11° N, 122.34° W) (Le Boeuf and Laws 1994) (Figure 1).
 Our objectives were: 1) to evaluate the accuracy of UAS photogrammetry for
 estimating mass in adult female northern elephant seals and 2) to examine
 the effect of body position on UAS mass estimates. Our error estimates
 were comparable to other ground-based studies that used multiple
 photogrammetric measurements to estimate mass (Table 1) and slightly
 higher than the only other overhead drone study (Krause et al. 2017),
 possibly due to lower camera resolution. This error is also slightly
 higher than previous mass estimates derived from morphometric measurements
 obtained during manual procedures (2.8% for Weddell seals Leptonychotes
 weddellii (Shero et al. 2014) and 4% for elephant seals (Crocker pers.
 comm)) but results in significantly less disturbance. Errors in estimated
 mass were marginally better when we used dorsal footprint area (R2= 0.895)
 than lateral footprint area (R2= 0.822), suggesting that our UAS mass
 estimates are robust to changes in body position. In summary,
 photogrammetric measurements from a single, vertical image obtained using
 UAS provide a promising approach for estimating the body mass of pinnipeds
 and similar approaches can be used to find species-specific calibration
 equations. Mass measurements can inform ecosystem-based resource
 management (Boyd et al. 2006) by providing information about the
 inter-annual productivity of the ocean environment and in turn individual,
 population, and ecosystem-level health in marine mammals (Krause et al.
 2017).

title: Seasonal pulse dynamics of CO2 and N2O, but not NOx, are modulated by exotic grass invasion in California coastal sage scrub

description: Aims
             To assess impacts of exotic grass invasion on nutrient losses from California coastal sage scrub (CSS), we quantified interactive effects of season, exotic grass litter, and plant cover type on wetting-induced emissions of carbon and nitrogen trace gases from CSS soils. Methods             We added grass litter to plots dominated by native Erioginum fasciculatum or exotic Schismus barbatus in invaded California CSS. In both dry and wet seasons, we conducted 48-hour wetting experiments and measured soil emissions of CO2, N2O, and NOx. Results             CO2 and N2O pulses appeared 15 minutes post-wetting, diminishing within twelve hours. NOx peaked between 6 to 12 hours, remaining elevated at 48 hours. Dry-season pulses were seven times higher than wet-season pulses. Grass litter amendments increased CO2 and dry-season N2O pulses without significantly altering NOx pulses. Grass cover reduced CO2 pulses compared to shrub cover. Conclusions                 Our results suggest that CSS soils produce stronger trace gas pulses of CO2, N2O, and NOx during the dry season when wetting is less frequent. Although grass cover potentially constrains soil CO2 respiration, grass litter loading during the dry season may provide carbon-rich substrates that stimulate additional microbial production of CO2 and N2O but not NOx.

title: Data from: Flat latitudinal diversity gradient caused by the Permo-Triassic mass extinction

description: The latitudinal diversity gradient (LDG) is recognized as one of the most
 pervasive, global patterns of present-day biodiversity. However, the
 controlling mechanisms have proved difficult to identify because many
 potential drivers covary in space. The geological record presents a unique
 opportunity for understanding the mechanisms which drive the LDG by
 providing a direct window to deep time biogeographic dynamics. Here we
 used a comprehensive database containing 52,318 occurrences of marine
 fossils to show that the shape of LDG changed greatly during the
 Permian-Triassic mass extinction from showing a significant tropical peak
 to a flattened LDG. The flat LDG lasted for the entire Early Triassic (~5
 million years) before reverting to a modern-like shape in the Middle
 Triassic. The environmental extremes that prevailed globally, especially
 the dramatic warming, likely induced selective extinction in low latitudes
 and accumulation of diversity in high latitudes through origination and
 poleward migration, which combined together account for the flat LDG of
 the Early Triassic.

title: Genomic tests of body plan transitions from bilateral to pentameric symmetry in Echinoderms

description: Echinoderms are an exceptional group in bilaterians in that they develop
 pentameral adult symmetry from a bilaterally symmetric larva. However, the
 genetic basis in evolution and development of this unique transformation
 remains to be clarified. Here we report newly sequenced genomes,
 developmental transcriptomes, and proteomes of diverse echinoderms
 including the green sea urchin (L. variegatus), a sea cucumber (A.
 japonicus), and with particular emphasis on progeny of the
 earliest-diverged deuterostome, the feather star (A. japonica). We learned
 that the last common ancestor of echinoderms retained a well-organized Hox
 cluster genes reminiscent of the hemichordate, and had gene sets involved
 in endoskeleton development. Further, unlike in other animal groups, the
 most conserved developmental stages was not at the body plan establishing
 phase, and genes normally involved in bilaterality appear to function in
 pentameral axes development. These results enhance our understanding of
 the divergence of protostomes and deuterostomes almost 500 mya.

title: Assessing corrosion resistance of 2D nanomaterial-based coatings on stainless steel substrates

description: Two dimensional (2D) materials have elicited considerable interest in the
 past decade due to a diverse array of novel properties ranging from high
 surface to mass ratios, a wide range of band gaps (insulating boron
 nitride to semiconducting transition metal dichalcogenides), high
 mechanical strength and chemical stability. Given the superior
 chemo-thermo-mechanical properties, 2D materials may provide
 transformative solution to a familiar yet persistent problem of
 significant socio-economic burden: the corrosion of stainless steel (SS).
 With this broader perspective, we investigate corrosion resistance
 properties of stainless steel coated with 2D nanomaterials; molybdenum
 disulfide (MoS2), boron nitride (BN), bulk graphite in 3.5 wt. % aqueous
 NaCl solution. The nanosheets were prepared by a novel liquid phase
 exfoliation technique and the coatings were made by a paint brush to
 achieve uniformity.  Open circuit potential (OCP) and
 potentiodynamic plots indicate the best corrosion resistance is provided
 by the MoS2 and the BN coatings. Superior performance of the coating is
 attributed low electronic conductivity, large flake size, and uniform
 coverage of SS substrate, which likely impeded the corrosive ions from the
 solution to diffuse through the coating.
description: Surface morphologies of the bare and coated SS samples were
 observed using a Carl Zeiss™ EVO MA 10 scanning electron microscope (SEM).
 Energy dispersive spectra (EDS) were collected using a Zeiss Gemini
 scanning electron microscope (SEM) at 10–30 keV. To observe layered
 electrode morphology, a focused Ga<sup>+</sup> ion beam (Zeiss
 Auriga FIB-SEM) was used. For electrochemical/corrosion testing purposes,
 a 3-electrode set-up was used. This set-up was connected to a CHI 660E
 electrochemical workstation.
