title: Data from: Rates and processes of aeolian soil erosion in West Greenland

description: In arid landscapes across the globe, aeolian processes are key drivers of
 landscape change, but arid Arctic regions are often overlooked. In the
 Kangerlussuaq region of West Greenland, strong katabatic winds have
 removed discrete patches of soil and vegetation, exposing unproductive
 glacial till and bedrock. Although lake-sediment records suggest that
 landscape destabilization began approximately 1000 years ago, the upland
 soil erosion has never been directly dated. We use a novel application of
 lichenometry to estimate the rates and timing of soil erosion. We show
 that the formation of deflation patches occurred approximately
 800–230 years ago, in general agreement with lake-sediment records. In
 West Greenland, the ‘Little Ice Age’ (AD 1350–1880) was characterized by a
 cold and arid climate, conditions that increased susceptibility to
 erosion. On average, deflation patches are expanding at a rate of 2.5 cm
 yr−1, and variation in the rate of patch expansion cannot be explained by
 proximity to the Greenland Ice Sheet (GrIS), slope, aspect, elevation, or
 patch size. An erosional threshold exists in this aeolian system, with
 climate conditions necessary for patch formation likely harsher than those
 necessary for continued patch expansion, a result that has implications
 for land management in arid regions. Currently, deflation patches are
 expanding throughout the study region and are forming in areas close to
 the GrIS, but future deflation rates are dependent on projected climate
 and potential land-use changes. Our results stress the importance of
 aeolian processes in arid polar landscapes such as Kangerlussuaq, and
 demonstrate the use of aeolian landforms in paleoclimate reconstructions
 and predicting future landscape change.

title: Data from: Stimulus background influences phase invariant coding by correlated neural activity

description: We recently reported that correlations between the activities of
 peripheral afferents mediate a phase invariant representation of natural
 communication stimuli that is refined across successive processing stages
 thereby leading to perception and behavior in the weakly electric fish
 Apteronotus leptorhynchus (Metzen et al., 2016). Here, we explore how
 phase invariant coding and perception of natural communication stimuli are
 affected by changes in the sinusoidal background over which they occur. We
 found that increasing background frequency led to phase locking, which
 decreased both detectability and phase invariant coding. Correlated
 afferent activity was a much better predictor of behavior as assessed from
 both invariance and detectability than single neuron activity. Thus, our
 results not only provide further evidence that correlated activity likely
 determines perception of natural communication signals, but also provide a
 novel explanation as to why these preferentially occur on top of low
 frequency as well as low intensity sinusoidal backgrounds.

title: Data from: Detection of invasive mosquito vectors using environmental DNA (eDNA) from water samples

description: Repeated introductions and spread of invasive mosquito species (IMS) have
 been recorded on a large scale these last decades worldwide. In this
 context, members of the mosquito genus Aedes can present serious risks to
 public health as they have or may develop vector competence for various
 viral diseases. While the Tiger mosquito (Aedes albopictus) is a
 well-known vector for e.g. dengue and chikungunya viruses, the Asian bush
 mosquito (Ae. j. japonicus) and Ae. koreicus have shown vector competence
 in the field and the laboratory for a number of viruses including dengue,
 West Nile fever and Japanese encephalitis. Early detection and
 identification is therefore crucial for successful eradication or control
 strategies. Traditional specific identification and monitoring of
 different and/or cryptic life stages of the invasive Aedes species based
 on morphological grounds may lead to misidentifications, and are
 problematic when extensive surveillance is needed. In this study, we
 developed, tested and applied an environmental DNA (eDNA) approach for the
 detection of three IMS, based on water samples collected in the field in
 several European countries. We compared real-time quantitative PCR (qPCR)
 assays specific for these three species and an eDNA metabarcoding approach
 with traditional sampling, and discussed the advantages and limitations of
 these methods. Detection probabilities for eDNA-based approaches were in
 most of the specific comparisons higher than for traditional survey and
 the results were congruent between both molecular methods, confirming the
 reliability and efficiency of alternative eDNA-based techniques for the
 early and unambiguous detection and surveillance of invasive mosquito
 vectors. The ease of water sampling procedures in the eDNA approach tested
 here allows the development of large-scale monitoring and surveillance
 programs of IMS, especially using citizen science projects.

title: Data from: Amplicon pyrosequencing late Pleistocene permafrost: the removal of putative contaminant sequences and small-scale reproducibility

description: DNA sequencing of ancient permafrost samples can be used to reconstruct
 past plant, animal and bacterial communities. In this study, we assess the
 small-scale reproducibility of taxonomic composition obtained from
 sequencing four molecular markers (mitochondrial 12S ribosomal DNA (rDNA),
 prokaryote 16S rDNA, mitochondrial cox1 and chloroplast trnL intron) from
 two soil cores sampled 10 cm apart. In addition, sequenced control
 reactions were used to produce a contaminant library that was used to
 filter similar sequences from sample libraries. Contaminant filtering
 resulted in the removal of 1% of reads or 0.3% of operational taxonomic
 units. We found similar richness, overlap, abundance and taxonomic
 diversity from the 12S, 16S and trnL markers from each soil core. Jaccard
 dissimilarity across the two soil cores was highest for metazoan taxa
 detected by the 12S and cox1 markers. Taxonomic community distances were
 similar for each marker across the two soil cores when the chi-squared
 metric was used; however, the 12S and cox1 markers did not cluster well
 when the Goodall similarity metric was used. A comparison of plant
 macrofossil vs. read abundance corroborates previous work that suggests
 eastern Beringia was dominated by grasses and forbs during cold stages of
 the Pleistocene, a habitat that is restricted to isolated sites in the
 present-day Yukon.

title: Wetland water descriptive characteristics and soil characteristics in response to experimental warming, flooding, and goose herbivory, Yukon-Kuskokwim Delta (Western Alaska, USA) (2023-2024)

description: This dataset was created to understand flood water chemistry, soil characteristics, root biomass, and temperature responses to warming, flooding, and goose herbivory in the Yukon-Kuskokwim (Y-K) Delta (western Alaska, USA). We conducted a two-year field experiment in which we passively increased temperatures, simulating periodic tidal flooding at two intensity levels (low and high) during the 2022 and 2023 summer growing season. Our treatments reflect changes expected in the Y-K Delta in the next 10-20 years. We conducted the experiment in two wetlands (lowland and upland wetland) with different elevations and flooding histories: a wet sedge-shrub meadow and a transitional wet community between the meadow and tundra. In 2023 and 2024, we collected flood water salinity and pH, and above-ground and below-ground temperature. However, floodwater nutrients, soil salinity, soil bulk density, soil volumetric water content, root biomass, and soil organic matter were collected only in 2024.

title: Data from: Sex differentiation in grayling (Salmonidae) goes through an all-male stage and is delayed in genetic males who instead grow faster

description: Fish populations can be threatened by distorted sex ratios that arise
 during sex differentiation. Here we describe sex differentiation in a wild
 grayling (Thymallus thymallus) population that suffers from distorted sex
 ratios. We verified that sex determination is linked to the sex
 determining locus (sdY) of salmonids. This allowed us to study
 sex-specific gene expression and gonadal development. Sex-specific gene
 expression could be observed during embryogenesis and was strong around
 hatching. About half of the fish showed immature testes around eleven
 weeks after fertilization. This phenotype was mostly replaced by the
 “testis-to-ovary” or “ovaries” phenotypes during development. The gonads
 of the remaining fish stayed undifferentiated until six months after
 fertilization. Genetic sexing revealed that fish with undifferentiated
 gonads were all males, who grew larger than the genetic females during the
 observational period. Only 12% of the genetic males showed testicular
 tissue six months after fertilization. We conclude that sex
 differentiation starts before hatching, goes through an all-male stage for
 both sexes (which represents a rare case of “undifferentiated”
 gonochoristic species that usually go through an all-female stage), and is
 delayed in males. During these juvenile stages males grow faster than
 females instead of developing their gonads.

title: Data from: In the eye of the beholder: visual mate choice lateralization in a polymorphic songbird

description: Birds choose mates on the basis of colour, song and body size, but little
 is known about the mechanisms underlying these mating decisions. Reports
 that zebra finches prefer to view mates with the right eye during
 courtship, and that immediate early gene expression associated with
 courtship behaviour is lateralized in their left hemisphere suggest that
 visual mate choice itself may be lateralized. To test this hypothesis, we
 used the Gouldian finch, a polymorphic species in which individuals
 exhibit strong, adaptive visual preferences for mates of their own head
 colour. Black males were tested in a mate-choice apparatus under three eye
 conditions: left-monocular, right-monocular and binocular. We found that
 black male preference for black females is so strongly lateralized in the
 right-eye/left-hemisphere system that if the right eye is unavailable,
 males are unable to respond preferentially, not only to males and females
 of the same morph, but also to the strikingly dissimilar female morphs.
 Courtship singing is consistent with these lateralized mate preferences;
 more black males sing to black females when using their right eye than
 when using their left. Beauty, therefore, is in the right eye of the
 beholder for these songbirds, providing, to our knowledge, the first
 demonstration of visual mate choice lateralization.

title: Data from: Convergence of life history phenotypes in a Trinidadian killifish (Rivulus hartii)

description: Convergent evolution is characterized by the independent evolution of
 similar phenotypes within similar selective environments. Previous work on
 Trinidadian killifish, Rivulus hartii, demonstrated repeatable life
 history differences across communities that differ in predation intensity.
 These studies were performed in rivers located on the south slope of
 Trinidad’s Northern Range Mountains. There exists a parallel series of
 rivers on the north slope of these mountains. As on the south slope,
 Rivulus is found across a gradient of fish predation. However, the
 predatory fish species in north-slope rivers are derived from marine
 families, whereas south-slope rivers contain a predatory fish fauna
 characteristic of the South American mainland. If predator-induced
 mortality and the associated indirect effects are the causal factors
 selecting for life history patterns in Rivulus, and these are similar in
 north and south-slope rivers, then the specific predatory species should
 be interchangeable and we would expect convergence of life history
 phenotypes across slopes. Here, we characterize the life history
 phenotypes of Rivulus from north-slope communities. We find similar
 patterns of life history divergence across analogous predator communities.
 Between slopes, minor differences in Rivulus life history traits exist and
 one potential cause of these differences is the abundance of Macrobrachium
 prawns in north-slope rivers.

title: Data from: The thermal dependency of locomotor performance evolves rapidly within an invasive species

description: Biological invasions can stimulate rapid shifts in organismal performance,
 via both plasticity and adaptation. We can distinguish between these two
 proximate mechanisms by rearing offspring from populations under identical
 conditions, and measuring their locomotor abilities in standardized
 trials. We collected adult cane toads (Rhinella marina) from invasive
 populations that inhabit regions of Australia with different climatic
 conditions. We bred those toads, and raised their offspring under
 common-garden conditions before testing their locomotor performance. At
 high (but not low) temperatures, offspring of individuals from a hotter
 location (northwestern Australia) outperformed offspring of conspecifics
 from a cooler location (northeastern Australia). This disparity indicates
 that, within less than 100 years, thermal performance in cane toads has
 adapted to the novel abiotic challenges that cane toads have encountered
 during their invasion of tropical Australia.

title: Data from: Variation of carbon contents in eelgrass (Zostera marina) sediments implied from depth profiles

description: Seagrass meadows are able to store significant amounts of organic carbon
 in their underlying sediment but global estimates are uncertain partly due
 to spatiotemporal heterogeneity between areas and species. In order to
 provide robust estimates, there is a need to better understand the fate
 of, and mechanisms behind, organic carbon storage. In this observational
 study, we analyse a suite of biotic and abiotic parameters in sediment
 cores from 47 different eelgrass (Zostera marina) beds spanning the
 distributional range of the Northern Hemisphere. Depth profiles revealed
 three patterns of vertical distribution where POC either increased,
 decreased, or showed no distinct pattern with sediment depth. These
 categories exhibited distinct profiles of δ13C and C:N ratios, where high
 POC profiles had a proportionally larger storage of eelgrass-derived
 material whereas low POC profiles were dominated by phytoplanktonic and
 macroalgal material. However, high POC did not always translate into high
 carbon density. Along with better constrained sedimentation rates, these
 results can ultimately contribute to our understanding of carbon content
 in seagrass beds.

title: Data from: Morphology and geography predict the use of heat conservation behaviours across birds

description: 1. Heat conservation behaviours in birds in part involve postural
 adjustments to regulate the area of exposed body surfaces. However, the
 occurrence of these behaviours across birds, and the factors that explain
 their use across bird species, remain poorly known. 2. We examined the
 occurrence of three distinctive bird behaviours - back rest (where the
 bill is tucked into the plumage), standing on one leg, and sitting -
 across 852 bird species using a Bayesian phylogenetic comparative
 analytical approach, examining the phylogenetic signal in, and ecological
 correlates of, these behaviours. 3. All three behaviours were far from
 ubiquitous across species: only a third to a half of species in our
 analysis have been confirmed to use each behaviour. The behaviours all
 exhibited significant phylogenetic signal indicating differential usage
 across clades. 4. All three behaviours were more commonly reported in bird
 species studied at higher latitudes. Back rest was also more often
 observed in species that have longer bills, relative to their body size,
 while standing on one leg was associated with longer relative tarsus
 length. Sitting behaviour was more common in heavier birds. 5. The results
 suggest the use of these postures is related to environment (climate) and
 morphology (appendage length), and therefore most likely is associated
 with the need to mitigate heat loss across the exposed body surfaces.
 However other potential functions of these postures, such as alleviating
 biomechanical load associated with large appendages and bodies, or the
 need to minimise energetic expenditure, are possible.

title: Data from: Increased natural reproduction and genetic diversity one generation after cessation of a steelhead trout (Oncorhynchus mykiss) conservation hatchery program

description: Spatial and temporal fluctuations in productivity and abundance confound
 assessments of captive propagation programs aimed at recovery of
 Threatened and Endangered populations. We conducted a 17 year
 before-after-control-impact experiment to determine the effects of a
 conservation hatchery program for anadromous steelhead trout (Oncorhynchus
 mykiss) on a key indicator of natural reproduction (naturally produced
 nests or 'redds'). The supplemented population exhibited a
 significant (2.6-fold) increase in redd abundance in the generation
 following supplementation. Four non-supplemented (control) populations
 monitored over the same 17 year period exhibited stable or decreasing
 trends in redd abundance. Expected heterozygosity in the supplemented
 population increased significantly. Allelic richness increased, but to a
 lesser (non-significant) degree. Estimates of the effective number of
 breeders increased from a harmonic mean of 24.4 in the generation before
 supplementation to 38.9 after supplementation. Several non-conventional
 aspects of the captive rearing program may have contributed to the
 positive response in the natural population.
