title: Data for: Seasonal acceleration of Petermann Glacier, Greenland, from changes in subglacial hydrology

description: Petermann Glacier, a major outlet glacier of Northern Greenland, drains a
 marine-based basin vulnerable to destabilization. Using satellite radar
 interferometry data from the Sentinel-1a/b missions, we observe a seasonal
 glacier acceleration of 15% in the summer, from 1,250 m/yr to 1,500 m/yr
 near the grounding line, but the physical drivers of this seasonality have
 not been elucidated. Here, we use a subglacial hydrology model coupled
 one-way to an ice sheet model to evaluate the role of subglacial hydrology
 as a physical mechanism explaining the seasonality in speed. We model the
 basal effective pressure using the Glacier Drainage System model which
 then forces the Ice-sheet and Sea-level System Model. We find an excellent
 agreement between the observed and modeled velocity in terms of magnitude
 and timing, and conclude that seasonal changes in subglacial hydrology are
 sufficient to explain the observed seasonal speed up of Petermann Glacier.
 This data publication provides all of the scripts and data necessary to
 initialize and run the subglacial hydrology model and ice sheet model used
 in this work (Manuscript number 2022GL098009). We also provide the model
 output and the scripts used to create the figures in the manuscript and
 the animations in the supplemental document. Several data sets are also
 made available here, including integrated melt water runoff derived from
 the regional climate model, MAR (Modèle Atmosphérique Régional), which is
 used to force the hydrology model, and daily average effective pressure
 derived from the hydrology model output, which is used to force the ice
 sheet model. These files combined are sufficient to reproduce all results
 and figures presented in this work.

title: Data from: Individual and sex-related patterns of prolonged flights during both day and night by great reed warblers crossing the Mediterranean Sea and Sahara Desert

description: A wide variety of the barrier crossing strategies exist among migrating
 songbirds, ranging from strict nocturnal flights to non-stop flights over
 a few days. We evaluate barrier crossing strategies in a nocturnally
 migrating songbird crossing the Mediterranean Sea and the Sahara Desert,
 the great reed warbler, exploring variation between the sexes and within
 individuals. We used data from 31 year-round light-level geolocators
 tracks from 26 individuals (13 males and 13 females), with four
 individuals tracked for 2–3.5 consecutive years. Almost all individuals
 (25 of 26) prolonged their flights into the day at least on one occasion.
 The mean duration of these prolonged flights was 19.9 h and did not differ
 between sexes or seasons. Fifteen birds performed non-stop flights during
 more than one full day and night (≥ 24 h; mean = 31.9 h; max = 55 h) in
 autumn and/ or spring, but these flights were generally too short to cross
 an entire barrier (such as the Sahara Desert) in one non-stop flight.
 Patterns of prolonged flights showed considerable within-individual
 variation in females between seasons (autumn versus spring) and in both
 males and females between years, suggesting high individual flexibility in
 migration strategy. Significantly more males than females performed
 prolonged flights during autumn migration, but not spring, possibly
 reflecting sex-specific carry-over effects. We conclude that great reed
 warblers have the ability to conduct prolonged continuous flights for up
 to several nights and days, which potentially would allow them to cross
 the Sahara Desert in one non-stop flight. However, they typically use a
 mixed strategy of several nocturnal flights with intermittent stopovers in
 combination with 1–3 prolonged flights. Prolonged flights covered less
 than half (44%) of the total flight time across the barriers, and the
 diurnal parts of the flights covered only 18% of this time.

title: Population genetic structure associated with a landscape barrier in the Western Grasswren (Amytornis textilis textilis)

description: Dispersal patterns can dictate genetic population structure, and
 ultimately population resilience, through maintaining gene flow and
 genetic diversity. However, geographic landforms, such as peninsulas, can
 impact dispersal patterns and thus be a barrier to gene flow. Here, we use
 13,375 genome-wide single-nucleotide polymorphisms (SNPs) to evaluate
 genetic population structure and infer dispersal patterns of the Western
 Grasswren (Amytornis textilis textilis; WGW, n = 140) in the Shark Bay
 region of Western Australia. We found high levels of genetic divergence
 between subpopulations on the mainland (Hamelin) and narrow peninsula
 (Peron). In addition, we found evidence of further genetic sub-structuring
 within the Hamelin subpopulation, with individuals collected from the
 western and eastern regions of a conservation reserve forming separate
 genetic clusters. Spatial autocorrelation analysis within each
 subpopulation revealed significant local-scale genetic structure up to 35
 km at Hamelin and 20 km at Peron. In addition, there was evidence of male
 philopatry in both subpopulations. Our results suggest a narrow strip of
 land may be acting as a geographic barrier in the WGW, limiting dispersal
 between a peninsula and mainland subpopulation. In addition, heterogeneous
 habitat within Hamelin may be restricting dispersal at the local scale.
 Furthermore, there is evidence to suggest that the limited gene flow is
 asymmetrical, with directional dispersal occurring from the bounded
 peninsula subpopulation to the mainland. This study highlights the genetic
 structure existing within and between some of the few remaining WGW
 subpopulations, and shows a need for placing equal importance on
 conservation efforts to maintain them in the future.

title: Macroevolutionary analyses provide new evidence of phasmid wings evolution as a reversible process

description: The concept that complex ancestral traits can never be re-acquired after
 their loss is still widely accepted, despite phylogenetic and molecular
 approaches suggesting instances where phenotypes may have been lost
 throughout the evolutionary history of a clade and subsequently reverted
 back in derived lineages. One of the first and most notable examples of
 such a process is wing evolution in phasmids; this polyneopteran order of
 insects, which comprises stick and leaf insects, has played a central role
 in initiating a long-standing debate on the topic. In this study, a novel
 and comprehensive time tree including over 300 Phasmatodea species is used
 as a framework for investigating wing evolutionary patterns in the clade.
 Despite accounting for several possible biases and sources of uncertainty,
 macroevolutionary analyses consistently revealed multiple reversals to
 winged states taking place after their loss, and reversibility is coupled
 with higher species diversification rates. Our findings support a loss of
 or reduction in wings that occurred in the lineage leading to the extant
 phasmid most recent common ancestor, and brachyptery is inferred to be an
 unstable state unless co-opted for nonaerodynamic adaptations. We also
 explored how different assumptions of wing reversals probability could
 impact their inference: we found that until reversals are assumed to be
 over 30 times more unlikely than losses, they are consistently inferred
 despite uncertainty in tree and model parameters. Our findings demonstrate
 that wing evolution is a reversible and dynamic process in phasmids and
 contribute to our understanding of complex trait evolution.

title: Data from: Phosphorus limitation determines the quality of dissolved organic matter released by marine heterotrophic prokaryotes

description: We determined phosphorus (P) limitation effect on the quantity and quality
 of dissolved organic matter (DOM) released by heterotrophic prokaryotes
 (HP). We grew 2 single bacterial strains, Photobacterium angustum and
 Sphingopyxis alaskensis, and natural HP communities collected in fall and
 spring from the Mediterranean Sea, on glucose under 2 treatments:
 P-replete vs. P-limiting. DOM release by HP comprised up to 30 % of the
 initial carbon provided for growth. P availability influenced carbon
 allocation to different cellular processes (respiration vs. growth), but
 did not significantly affect the quantity of DOM released by HP. However,
 using fluorescence spectroscopy, we demonstrated an effect of P-limitation
 on DOM quality, with a predominance of humic-like compounds under
 P-limitation but protein-like compounds under P-repletion. Our results
 suggest that P-limitation could determine the fate of HP-derived DOM in
 the ocean, thus affecting the microbial carbon pump.
description: The data are collected in laboratory experiments testing
 phosphorus (P) limitation effect on the quantity and the quality of
 dissolved organic matter released by heterotrophic prokaryotes (HP-DOM).
 Two single bacterial strains and natural HP communities collected in fall
 and spring from the Mediterranean Sea, were grown on glucose under 2
 treatments: P-replete vs. P-limiting. Cell abundance was followed by flow
 cytometry. Inorganic nutrient, dissolved organic carbon, glucose and
 fluorescent DOM were measured at the onset (T0) and end of incubation
 (Tf). Samples at T0 were directly measured and Tf samples were filtered
 twice onto 0.2 polycarbonate filters.

title: Data from: Influences of summer warming and nutrient availability on Salix glauca L. growth in Greenland along an ice to sea gradient

description: The combined effects of climate change and nutrient availability on Arctic
 vegetation growth are poorly understood. Archaeological sites in the
 Arctic could represent unique nutrient hotspots for studying the long-term
 effect of nutrient enrichment. In this study, we analysed a time-series of
 ring widths of Salix glauca L. collected at nine archaeological sites and
 in their natural surroundings along a climate gradient in the Nuuk fjord
 region, Southwest Greenland, stretching from the edge of the Greenlandic
 Ice Sheet in the east to the open sea in the west. We assessed the
 temperature-growth relationship for the last four decades distinguishing
 between soils with past anthropogenic nutrient enrichment (PANE) and
 without (controls). Along the East–West gradient, the inner fjord sites
 showed a stronger temperature signal compared to the outermost ones.
 Individuals growing in PANE soils had wider ring widths than individuals
 growing in the control soils and a stronger climate-growth relation,
 especially in the inner fjord sites. Thereby, the individuals growing on
 the archaeological sites seem to have benefited more from the climate
 warming in recent decades. Our results suggest that higher nutrient
 availability due to past human activities plays a role in Arctic
 vegetation growth and should be considered when assessing both the future
 impact of plants on archaeological sites and the general greening in
 landscapes with contrasting nutrient availability.

 of <em>Salix glauca</em> L. and climate from the nine

title: Changes in the intensity of heartwood formation in Scots pine (Pinus sylvestris L.) ontogenesis

description: An essential stage in woody plant ontogeny (heartwood (HW) formation)
 determines tree resistance to weather conditions, wood quality (moisture,
 colour, resistance to biodegradation), and regulates the proportion of
 functionally active sapwood (SW) in the total trunk biomass. In this
 study, the patterns of HW formation depending on tree age and cambial age
 within the same tree were studied in the North-West of Russia in Scots
 pine in a lingonberry pine forest. It is shown that HW either repeats the
 trunk profile or shows a maximum proportion on average at the height of
 1.5 m. Models using the square root transformation and logarithm
 transformation have been proposed to predict the number of annual rings in
 HW depending on the cambial age. Multiple regression is proposed to
 predict the radial width in HW. Validation of the developed models on
 random trees gave a good result. HW formation begins at the age of 17–18
 years and continues at the rate of 0.3 rings per year for 20–30-year-old
 trees, 0.4–0.5 rings per year for 70–80-year-old trees, and about 0.7
 rings per year for 180-year-old trees. The lifespan of xylem parenchyma
 cells ranged from 10–15 years in 20-year-old trees to 70 years in
 180-year-old trees. At the age of the previous felling (70–80 years) the
 HW area in the trunk biomass is about 20%, and in 180-year-old pine
 forests, it increases to 50%. These data can be used to assess the role of
 old-growth forests in carbon sequestration.

title: Data From: Antibiotic treatment ameliorates the impact of stony coral tissue loss disease (SCTLD) on coral communities

description: Stony coral tissue loss disease has spread widely in the Caribbean and
 causes substantial changes to coral community composition because of its
 broad host range and high fatality rate. To reduce SCTLD impacts,
 intervention programs throughout the region have divers treating corals
 with antibiotics. We assessed the effect of antibiotic treatment in the
 British Virgin Islands by comparing coral communities at 13 treated sites
 to those at 13 untreated sites. The prevalence of white syndromes (assumed
 to be primarily SCTLD), the severity of white syndrome lesions, partial
 colony mortality and complete colony mortality all showed a pattern
 consistent with benefits of treatment: they were reduced at treated sites
 but only for species of medium- and high-susceptibility to SCTLD. In
 contrast, the prevalence and severity of lesions from other diseases, and
 other causes of tissue loss, were all unrelated to treatment. Re-ordering
 of rank abundance at the community-level was also consistent with a
 positive effect of treatment because rare, highly SCTLD-susceptible
 species increased slightly in relative cover at treated sites. Although
 there was limited statistical support for these responses individually,
 collectively the overall pattern of results indicates a modest beneficial
 effect of the intervention program. Diver-based intervention programs
 using antibiotics are thus a viable part of management plans for STLD at
 the epidemic stage.

title: The response of sub-adult savanna trees to successive fires of various seasons

description: Abstract In mesic savannas worldwide, trees experience frequent fires,
 almost all set by humans. Management fires are set to reduce or enhance
 tree cover. Success depends greatly on responses of sub-adult trees to
 such fires. To date, the number of successive years that sub-adult trees
 can resprout nor the number of years that they must resist being
 top-killed by successive fires, nor the requisite height, have been
 reported. In a six-year experimental field study in Guinean savannas of
 West Africa, we monitored annually the heights and responses of 1,765
 permanently tagged sub-adult trees under annual fires set in three
 different periods of the long dry season: early-dry season (EDS), mid-dry
 season (MDS) and late-dry season (LDS). Annual MDS fires are the common
 local management fires of these savannas. Results showed that overall, the
 proportion of sub-adults that resisted being top-killed differed across
 fire seasons. Further, resisting one fire gave a better chance of
 resisting the next. Only sub-adults that were able to resist direct damage
 for three successive EDS and MDS fires reached sufficient height to be
 recruited to the adult stage. Resistance height (avoiding topkill) was ∼1
 m for EDS and ∼2 m for both MDS and LDS fires. Recruitment height
 (threshold for transition to adult stage) was ∼3 m for EDS and ∼ 3.3 m for
 MDS fires. No height was great enough for sub-adult trees to be recruited
 to adult stages in LDS fire. Synthesis and applications: The results of
 this novel field study showed clearly that successive early- and mi-dry
 season fires can enhance tree density and that successive late-dry season
 fires alone reduce tree density in Guinean savannas. The results suggest
 that a planned regime of these seasons of fire could be used to maintain
 the desired tree density in Guinean savannas and may inform fire
 management in other mesic savannas where goals are to increase or decrease
 tree densities. It also provides relevant information for comparative
 studies on the mechanisms of recruitment of sub-adult trees to an adult
 stage in all mesic savannas, a process that ultimately determines savanna
 physiognomy.

 seasons were collected in September from 2014 to 2019.

title: Fish zeta diversity responses to human pressures and cumulative effects across a freshwater basin

description: Aim: Declining biodiversity across ecosystems and myriad human pressures
 necessitate high-level regional assessments for effective management.
 Evaluation of biodiversity patterns and stressor accumulation through beta
 diversity and cumulative effect analyses are two key methods for
 management prioritization. This study links these concepts to develop a
 novel cumulative effect metric based on beta diversity responses.
 Location: Fraser River basin, British Columbia, Canada. Methods:
 Multi-Site Generalized Dissimilarity Models were used to evaluate
 non-linear relationships between fish species compositional differences
 (ζn, number of shared species across any number of watersheds compared)
 and human pressure, environmental, and geospatial differences among all
 watersheds and within low, mid-, and high elevation clusters. A cumulative
 effect metric was calculated as the sum of response values generated by
 the model for each human pressure variable specific to each watershed,
 when evaluated for ζ2 (equivalent to pairwise beta diversity). This metric
 was tested against the Local Contribution of each watershed to Beta
 Diversity to determine whether watersheds with unique communities had low
 cumulative effects and are therefore candidates for conservation, and
 conversely, whether watersheds with non-distinctive communities had high
 cumulative effects and warrant restoration. Species Contributions to Beta
 Diversity were also assessed across the basin. Results: Zeta diversity
 across low elevation watersheds indicated stronger filtering by human
 pressures than mid- and high elevations, which showed more stochastic
 community assembly. The relative importance and response to human
 pressures varied based on the diversity component (i.e., total diversity
 including compositional nestedness vs. turnover) and order of zeta (number
 of watersheds compared). Cumulative effects were negatively related to
 community uniqueness, supporting the use of these metrics for developing
 management priorities. Main Conclusions: This assessment contributes to
 biodiversity conservation efforts by identifying important watersheds,
 species, and human pressures to manage, as well as providing a cumulative
 effect metric directly based on biodiversity responses.

title: Data from: Efficacy of spotlights and thermal cameras to detect lions, Panthera leo, and spotted hyenas, Crocuta crocuta, depends on species and management regime

description: Accurate abundance estimates can contribute to effective management of
 large carnivore populations. Lion, Panthera leo, and spotted hyena,
 Crocuta crocuta, populations are frequently estimated at night by
 eliciting their approach using broadcasted vocalizations. Spotlights are
 typically used to observe these species on approach but can disturb
 animals and adversely affect counts. We compared the efficacy of spotlight
 with red filters and forward looking infrared (FLIR) thermal monocular to
 enumerate lions and spotted hyenas in Serengeti National Park (SNP;
 non-hunted area) and Maswa Game Reserve (MGR; hunted area), Tanzania,
 during 2015−2017. We established 119 call-in sites in SNP and 20 in MGR
 and conducted repeated call-ins at 1–2 week intervals. During call-ins we
 conducted systematic paired counts using both devices. We assessed the
 influence of device order, species, hunting regime, and land cover on
 species counts. We found that FLIR was more efficacious for counting
 hyenas in MGR and spotlight for counting lions in SNP. We found evidence
 for temporary artificial light disturbance in MGR, as counts were higher
 when FLIR was used as the second device. Habitat type within 200 m of
 call-in sites did not influence device performances. Greater spotlight
 efficacy in SNP is a likely consequence of lower perceived risk and less
 anthropogenic disturbance compared to MGR. To improve accuracy of counts
 and subsequent population estimates for lions and spotted hyenas, we
 recommend consideration of variation in device efficacy, based on species
 surveyed and management regime.
