title: Global catalog of alluvial fans and other fan-shaped features on Mars, with morphology characteristics

description: Alluvial fans on Mars record evidence of depositional environments that
 represent the final era of potential habitability on the Martian surface.
 Alluvial fan deposits can often look similar to deltaic or fluvial systems
 in visible remote sensing images but are firmed in depositional and
 climatic environments that are distinct from those that lead to other
 radial depositional features. In order to better constrain the regional
 and global depositional environments and further inform the analysis of
 the sedimentary history of Mars, this study expands the global catalog of
 alluvial fans on Mars by adding newly identified features and
 characterizing all new and previously identified features based on
 morphologic parameters. Based on how closely they fit the morphologic
 definition of alluvial fans, as established by terrestrial sedimentology,
 each feature is classified as either an alluvial fan or another
 depositional feature. The .csv files made available here contain the full
 global database of features investigated in the referenced paper (Mondro
 et al., 2022). Five different .csv files are included, divided according
 to feature classification category based on the morphological parameters
 described in Mondro, et al. 2022.  The five classification
 categories are: alluvial fan, possible alluvial fan, non-alluvial radial
 feature (NARF), small feature, and non-fan. For each individual
 depositional feature, the database contains the lat/long location of the
 fan apex, a reference to the first publication to identify it, the results
 of the characterization parameters, and the final morphologic
 classifications. The characterization parameters are planform shape,
 radius (meters), average radial slope (degrees), adjusted average radial
 slope (degrees), and radial profile shape. When a parameter is listed as
 NA, the morphologic categorization for that class of feature did not
 include that specific parameter. See referenced paper for more detail on
 methodology and discussion of results: Mondro, C.A., J.E. Moersch, C.M.

title: Changes in microbial community structure and functioning with elevation are linked to local soil characteristics as well as climatic variables

description: Mountain forests are important carbon stocks but are threatened by
 increased insect outbreaks and climate driven forest conversion. Soil
 microorganisms play an eminent role in nutrient cycling in forests and
 form the basis of soil food webs. Uncovering the driving factors shaping
 microbial communities and functioning at mountainsides worldwide is of
 importance to better understand their dynamics at local and global scales.
 We investigated microbial communities and their drivers along an
 elevational gradient of primary forests at Changbai Mountain, China. We
 analysed substrate-induced respiration and phospholipid fatty acids (PLFA)
 in litter and two soil layers at seven sites. In the litter layer the
 increase in microbial biomass (Cmic) as well as in stress indicator ratios
 with elevation were negatively correlated with Ca concentrations
 indicating increased nutritional stress in high microbial biomass
 communities at sites with lower Ca availability. PLFA profiles in litter
 separated low and high elevations, this was less pronounced in soil,
 suggesting that leaflitter functions as buffer for soil microbial
 communities. Annual variations in temperature correlated with PLFA
 profiles in all layers, while annual variations in precipitation
 correlated with PLFA profiles in upper soil only. Furthermore, the
 availability of resources, soil moisture, Ca concentrations and pH
 structured the microbial communities. Pronounced changes in Cmic and
 stress indicator ratios in the litter layer between pine dominated (800 –
 1100 m) and spruce dominated (1250 – 1700 m) forests indicated a shift in
 the structure and functioning of microbial communities between forest
 types. The study highlights strong changes in microbial community
 structure and functioning along elevational gradients, but also shows that
 these changes and their driving factors vary between layers. Besides
 annual variations in temperature and precipitation, carbon accumulation
 and nitrogen acquisition shape changes in microbial communities with
 elevation at Changbai Mountain.

title: Timing and synchrony of migration in a freshwater fish: consequences for survival

description: Animal migration is one of the most spectacular and visible behavioural
 phenomena in nature with profound implications for a range of ecological
 and evolutionary processes. Successful migration hinges on the ability to
 exploit temporary resources (e.g. food) and evade threats (e.g. predators)
 as they arise, and thus the timing of migration is often regarded as a
 dominant predictor of individual migratory success. However, with the
 exception of intensively studied taxa (mainly birds), relatively few
 studies have investigated inter-individual annual and seasonal variation
 in migratory timing and performance, or tested predictions on how
 migration across high and low predation-risk habitats may exert selection
 on migratory timing. In particular, studies that assess the survival
 consequences of variation in migratory timing remain rare, which is most
 likely due to the logistical challenges associated with monitoring
 survival success and population-level characteristics simultaneously.
 Here, we address the above-mentioned questions using roach Rutilus
 rutilus, a fish that migrates from lakes characterised by high-predation
 risk into low-risk streams during winter. Specifically, we used
 individual-based tracking of roach in two European lake systems over
 multiple migration periods (9 and 7 years, respectively), to obtain highly
 detailed (year-round scheduling, repeat journeys and the fate of
 individuals) data on the variability/synchrony of migratory timing in
 spring and autumn respectively. We report seasonal differences in the
 variability of migratory timing, with lower variance and higher migration
 synchrony in spring lake arrival timing as compared to autumn lake
 departure timing. Furthermore, the timing of autumn migration is more
 variable across years than the timing of spring migration. Secondly, we
 find that later arrival to the lake habitat is positively associated with
 apparent survival from one year to the next, whereas we found no effect of
 lake departure timing on survival probability. These findings represent
 rare evidence showing how intraspecific variation in timing in migratory
 fish differs across years and seasons, and how variation in timing can
 translate into survival consequences for prey in systems characterised by
 high predation risk. 
description: Data for this study consists of arrival and departure timing, as
 well as apparent survival from one year to the next of individual roach
 (<em>Rutilus rutilus</em>) migrating between lake habitats and
 connected streams. Data was collected for multiple years and from two
 different European lakes (Krankesjön and Sogård So) using passive
 biotelemetry with stationary and continuously operating antenna
 arrays.

title: Data from: How long does a brachiopod shell last on a seafloor? Modern mid-bathyal environments as taphonomic analogues of continental shelves prior to the Mesozoic Marine Revolution

description: Carbonate skeletal remains are altered and disintegrate at yearly to
 decadal scales in present-day shallow-marine environments with intense
 bioerosion and dissolution. Present-day brachiopod death assemblages are
 invariably characterized by poor preservation on continental shelves, and
 abundant articulated shells of brachiopods with well-preserved brachidia
 are thus not expected to be preserved if not rapidly buried. However, such
 preservation is paradoxically observed in shallow-water Paleozoic and
 Mesozoic brachiopod assemblages. Here, we show that a bathyal death
 assemblage time-averaged to several millennia (Adriatic Sea) consists of
 sediment-filled articulated shells of Gryphus vitreus with complete
 brachidia. Postmortem age distributions indicate that disintegration
 half-lives exceed several centuries (~500-1,700 years). The high frequency
 of articulated but centuries-old shells (&gt;50%) and the fitting of
 taphonomic models to postmortem ages indicate that disarticulation
 half-life is unusually long (~200 years). Rapid sediment filling of shells
 (1) inhibited disarticulation, loop fragmentation and colonization by
 coelobites and (2) induced precipitation of ferromanganese oxides at redox
 fronts within shells. Sediment-filled articulated shells, however, still
 resided at the sediment-water interface as indicated by encrusters and
 sponges that infested them after death. Sediment-filled shells
 disintegrated through bioerosion and wear when residence time in the
 taphonomically active zone exceeded ~2,000 years. We suggest that the
 articulation paradox is driven by the Mesozoic Marine Revolution (MMR)
 that escalated predation, bioturbation and organic matter recycling, all
 intensifying shell disintegration. A scenario with slow disarticulation in
 bathyal environments can be an analogue of conditions leading to
 preservation of articulated shells in shallow-water assemblages prior to
 the MMR.

title: Warm acclimation alters antioxidant defences but not metabolic capacities in the Antarctic fish, Notothenia coriiceps

description: The Southern Ocean surrounding the Western Antarctic Peninsula region is
 rapidly warming. Survival of members of the dominant suborder of Antarctic
 fishes, the Notothenioidei, will likely require thermal plasticity and
 adaptive capacity in key traits delimiting thermal tolerance. Herein, we
 have assessed the thermal plasticity of several cellular and biochemical
 pathways, many of which are known to be associated with thermal tolerance
 in notothenioids, including mitochondrial function, activities of aerobic
 and anaerobic enzymes, antioxidant defences,protein ubiquitination and
 degradation in cardiac, oxidative skeletal muscles and gill of Notothenia
 coriiceps warm acclimated to 4◦C for 22 days or 5◦C for 42 days. Levels of
 triacylglycerol (TAG) were measured in liver and oxidative and glycolytic
 skeletal muscles, and glycogen in liver and glycolytic muscle to assess
 changes in energy stores. Metabolic pathways displayed minimal thermal
 plasticity, yet antioxidant defences were lower in heart and oxidative
 skeletal muscles of warm-acclimated animals compared with animals held at
 ambient temperature. Despite higher metabolic rates at elevated
 temperature, energy storage depots of TAG and glycogen increase in liver
 and remain unchanged in muscle with warm acclimation. Overall, our studies
 reveal that N. coriiceps displays thermal plasticity in some key traits
 thatmay contribute to their survival as the Southern Ocean continues to
 warm.

title: Morphometric correlations between dietary and reproductive traits of two brachyuran crabs, Hemigrapsus sanguineus and Aratus pisonii

description: Many animals have flexible morphological traits that allow them to succeed
 in differing circumstances with differing diets available to them. For
 brachyuran crabs, claw height and gut size are diet-specific and largely
 reflect foraging strategies, while abdomen width reflects relative levels
 of fecundity. However, the link between claw size and diet has largely
 been documented only for primarily carnivorous crabs, while the link
 between diet and fecundity is strong in herbivorous crabs. We sought to
 determine the nature of the intraspecific relationship between claw size,
 dietary habits, and fecundity for two primarily herbivorous crab species,
 Hemigrapsus sanguineus and Aratus pisonii. Specifically, we examined
 whether claw size and/or abdomen width can be used as reliable measures of
 individual diet strategy. To test these hypotheses, we collected crabs and
 measured the dimensions of their claws, abdomens, and guts. By comparing
 these dimensions for each individual, we found that strongly predictive
 relationships do not exist between these traits for the primarily
 herbivorous species in our study. Thus, identifying external morphological
 features that can be used to assess diets of primarily herbivorous crabs
 remains elusive.
description: Data were obtained through measuring crabs that had been sampled
 and processed for other studies, and whose bodies were then stored in the
 lab. All data collection and processing is described in the
 manuscript.

title: Scaling of metabolic rate in hibernators: Translation of literature data: For a comment to Nespolo et al. (2022)

description: This spreadsheet provides a translation of data from the literature for
 the manuscript: Do bears hibernate in the woods? Comment on ‘Why bears
 hibernate? Redefining the scaling energetics of hibernation’, and includes
 both the background data for Figure 1 which is presented in the
 manuscript. Full reference for article it is commented on: Nespolo, R. F.,
 Mejias, C., and Bozinovic, F. Why bears hibernate? Redefining the scaling
 energetics of hibernation. Proc. R. Soc. B. 2022; 289(1973):20220456. We
 have made corrections to the data in the original article's Table S1,
 and translated empirical BMR data from literature instead of calculating a
 regression line from White, C.R. & Seymour, R.S. (2003). This
 changes the body mass where regression lines for Log (DDEHIB) and Log(BMR)
 cross, and thus where no savings from hibernation can be expected, from 75
 kg to over 2,250 kg and shows that bears hibernate to save energy.

title: Phenotypic plasticity contributes more to the variations in nutrient resorption than genetic differentiation in a grassland dominant

description: 1. Phenotypic plasticity and genetic differentiation are the two important
 processes determining the leaf nutrient resorption among and within plant
 species, which is critical for understanding the adaptability of plants.
 However, relative contributions of these two processes have never been
 quantified at a large geographical scale. 2. Here, we investigated
 intraspecific variations in nutrient resorption among 14 Stipa breviflora
 populations along a latitude gradient in 2018 and 2019. Furthermore, we
 sow seeds from these populations in two common gardens at different
 latitudes, and examined the variations in nutrient resorption. 3. Our
 results showed that nitrogen and phosphorus resorption efficiency (NRE and
 PRE) among S. breviflora populations in nature were positively related to
 latitude, while this trend disappeared in the common gardens. The
 heritability of NRE and PRE was 11.45 % and 16.78 %, respectively. These
 results suggested that phenotypic plasticity contributed much more than
 genetic variation to nutrient resorption of S. breviflora. Moreover, the
 structural equation modeling (SEM) suggested that latitude indirectly
 affected nutrient resorption mainly by altering soil nutrients. With the
 increasing of latitude, soil nutrients decreased while nutrient resorption
 increased. This suggested the main process regulating nutrient resorption
 is negative feedback to soil nutrient availability. 4. Our study provides
 new insights into the role of nutrient resorption in plant adaptations to
 geographic variations.

title: Data from: Local adaptation to seasonal cues at the fronts of two parallel, climate-induced butterfly range expansions

description: Climate change allows species to expand polewards, but non-changing
 environmental features may limit expansions. Daylength is unaffected by
 climate and drives life cycle timing in many animals and plants. Because
 daylength varies over latitudes, poleward-expanding populations must adapt
 to new daylength conditions. We studied local adaptation to daylength in
 the butterfly Lasiommata megera, which is expanding northwards along
 several routes in Europe. Using common garden laboratory experiments with
 controlled daylengths, we compared diapause induction between populations
 from the southern-Swedish core range and recently established marginal
 populations from two independent expansion fronts in Sweden. Caterpillars
 from the northern populations entered diapause in clearly longer
 daylengths than those from southern populations, with the exception of
 caterpillars from one geographically isolated population. The northern
 populations have repeatedly and rapidly adapted to their local daylengths,
 indicating that the common use of daylength as seasonal cue need not
 strongly limit climate-induced insect range expansions.

title: How does variation in total and relative abundance contribute to gradients of species diversity?

description: Patterns of biodiversity provide insights into the processes that shape
 biological communities around the world. Variation in species diversity
 along biogeographical or ecological gradients, such as latitude or
 precipitation, can be attributed to variation in different components of
 biodiversity: changes in the total abundance (i.e. more-individual
 effects) and changes in the regional species abundance distribution (SAD).
 Rarefaction curves can provide a tool to partition these sources of
 variation on diversity, but first must be converted to a common unit of
 measurement. Here, we partition species diversity gradients into
 components of the SAD and abundance using the effective number of species
 (ENS) transformation of the individual-based rarefaction curve. Because
 the ENS curve is unconstrained by sample size, it can act as a
 standardized unit of measurement when comparing effect sizes among
 different components of biodiversity change. We illustrate the utility of
 the approach using two datasets spanning latitudinal diversity gradients
 in trees and marine reef fish, and find contrasting results. Whereas the
 diversity gradient of fish was mostly associated with variation in
 abundance (86%), the tree diversity gradient was mostly associated with
 variation in the SAD (59%). These results suggest that local fish
 diversity may be limited by energy through the more-individuals effect,
 while species pool effects are the larger determinant of tree diversity.
 We suggest that the framework of the ENS-curve has the potential to
 quantify the underlying factors influencing most aspects of diversity
 change. --

title: No seasonal curtailment of the Eurasian Skylark’s (Alauda arvensis) breeding season in German heterogeneous farmland

description: The lack of suitable nesting sites is one key driver behind the farmland
 bird crisis in Europe. Winter cereals become impenetrable for
 ground-breeding birds like the Eurasian Skylark (Alauda arvensis),
 curtailing breeding time. Stable Skylark populations depend on multiple
 breeding attempts per year; thus, the widespread cultivation of winter
 cereals has strongly contributed to their tremendous decline. Crop
 diversification is thought to be a potential measure to counteract this
 development. Therefore, we explored how individual Skylarks respond to the
 decreasing suitability of winter cereals as nesting habitat in
 heterogeneous but otherwise conventionally managed farmland. Our study
 focused on: i) the degree to which Skylarks prematurely cease nesting
 activity, switch nesting habitats, or breed on linear structures like
 tramlines. Additionally, we analyzed: ii) if nest success decreases
 throughout the breeding season and iii) how often Skylarks make a
 successful breeding attempt per year. We radio-tagged 28 adults in a
 German population during April 2018 and 2019, tracked half of them for
 more than 3 months, and measured their breeding success. Additionally, we
 monitored nests of untagged pairs, resulting in 96 nests found. None,
 except one tagged individual, stopped breeding activity before July 1st.
 Home ranges were mainly stable, but Skylarks switched nesting habitats
 away from winter cereals to crops like sugar beet or set-aside. High-risk
 nesting sites like corn and linear structures played a minor role in
 breeding. Overall, Mayfield logistic regressions revealed no seasonal
 decrease in nest success, and tagged Skylarks had sufficient time to make
 1.5 – 1.8 breeding attempts, of which 0.8 were successful. We suggest that
 heterogeneous farmland in our study area, which enabled diversely composed
 home ranges, prevented a curtailment of the breeding season. Thus, our
 study reinforces the need for crop diversification which gives Skylarks a
 chance to survive in modern farmland.
