title: Data from: Drought-induced relocation of ant colonies and its consequences for the long-term spatial ecology of a population under stress

description: Maintaining a central refuge such as a nest or burrow can offer protection
 against environmental stressors but comes at the expense of the capacity
 to disperse to new locations. This trade-off with mobility can be
 detrimental when environmental conditions become adverse for extended
 periods, necessitating animals to relocate in order to track shifting
 niche envelopes. Long-lived ant colonies that invest in the construction
 of large nests are especially susceptible to changing environmental
 conditions. The Australian meat ant, Iridomyrmex purpureus, build large
 terrestrial nests at sites that balance shade and solar exposure.
 Long-term study of a population of meat ants showed low nest turnover and
 a stable spatial distribution of nests across typical rainfall years. With
 the onset of drought, a dramatic surge in the production of new nests
 occurred through a process of budding that far exceeded historic trends.
 This appears to have allowed colonies to relocate nests into areas with
 more favourable microclimate conditions in a strategy reminiscent of the
 production of runners in stressed plants. The consequence has also been
 the packing of nests into a narrow habitable zone that has resulted in an
 apparent increase in competition among large rival colonies. Following the
 break in drought and the thinning of some nests through abandonment,
 competition has progressively eased in later years. The surge in nest
 budding triggered by acute environmental stress in this population offers
 a possible strategy for long-lived colonies to effectively migrate across
 the landscape. With changes in environmental conditions becoming more
 frequent and severe with the climate crisis, any strategy available to
 central place foragers to track windows of preferred conditions are likely
 to become increasingly important.

title: Survival and cause-specific mortality in adult females of a northern migratory ungulate

description: Survival of ungulates can vary seasonally due to changing environmental
 conditions, e.g., weather or predation pressure. The wild forest reindeer
 (Rangifer tarandus fennicus, ‘WFR’) migrate between calving and wintering
 grounds. The annual cycle of female WFR includes four main seasons
 (wintering, calving, rutting and autumn migration) during which they are
 subject to different conditions, but almost nothing is known about their
 survival or mortality patterns. We measured survival in 305 GPS-tagged
 female WFR in two subpopulations in Finland (2010–2022). Data were
 analysed for inter-annual and seasonal patterns in survival and
 cause-specific mortality (predation, traffic, accidents and unknown
 causes) with known-fate models. Inter-annual survival in Suomenselkä (mean
 0.90) showed an increasing trend during the study and was higher than in
 Kainuu (mean 0.84) which showed a declining trend. Seasonal variation in
 survival was population dependent. Survival was lowest in Kainuu during
 the winter while in Suomenselkä, it was lowest during autumn migration.
 Concerning cause-specific mortality, seasonal variation mirrored variation
 in predation that was the primary cause of mortality (55% of cases).
 Wolves (Canis lupus) killed the majority of predated individuals (58%).
 Predation rates were two times higher in Kainuu where the wolf density was
 higher. We provide the first adult survival estimates for WFR and show
 that the seasonal variation in survival is clearly different between these
 two northern ungulate populations. This indicates that seasonal variation
 in survival is determined by site-dependent factors and cannot be
 generalised across populations. 
description: The data were collected by following animals with GPS-collars. It
 has been processed to include monthly information on whether the animal
 was alive or deceased during the months January 2010–April 2022.

title: Stability and change in male fertility patterns by cognitive ability across 32 birth cohorts

description: The relationship between cognitive ability (CA) and childbearing remains
 unsettled. Using Norwegian administrative registers with population
 coverage, we study how male lifetime fertility patterns differ across
 cognitive score groups, and how these changed across the 1950–1981 birth
 cohorts, covering a period characterized by rapid social and economic
 change. The analyses reveal systematic differences in fertility and
 fertility timing across CA groups, with high-scoring males having delayed
 but ultimately higher fertility than lower-scoring males. This pattern
 remains stable over time despite strong trends towards delayed and reduced
 fertility. The overall positive relationship between CA and fertility is
 primarily driven by high rates of childlessness in the lowest-scoring
 group, with low-scoring males showing higher rates of parity progression
 conditional on having children.
description: The data was derived from Norwegian administrative registers on
 loan from Statistics Norway. The population registry contributed
 information on births, deaths, citizenship category and parents, while
 data from the armed forces contained cognitive ability test scores from
 military conscription. A set of potential fathers was defined across the
 included birth cohorts, with the sample conditioned on being born to two
 Norwegian parents and being alive at age 18. Pseudonymous individual-level
 identifiers were used to identify each male's conscription test score
 (if scored) and their children (individuals of both sexes in the
 population registry with this individual as their assigned father). Father
 age at birth was calculated as the difference between father and
 child's birth cohort, and parity was assigned by sorting a
 father's children by birth year.

title: Data from: Narwhal (Monodon monoceros) echolocation click rates to support cue counting passive acoustic density estimation

description: The datasets correspond to the data used to obtain the results shown in
 the manuscript "Narwhal (Monodon monoceros) echolocation click rates
 to support cue counting passive acoustic density estimation". When
 the manuscript is accepted we will also edit and add here the full
 reference including the DOI of the publication.
description: The narwhals were
 live-captured each August in 2013-2016, and 2019, at the Hjørnedal field
 station, located near the southwestern tip of Milne Land in the Scoresby
 Sound fjord complex. They were tagged with sound and movement biologging
 tags (Acousonde tags). Acoustic recordings were either continuous (4
 whales, 25 811 Hz) or duty-cycled (4 whales), alternating between low and
 high sampling rates (8 min at 25 811 Hz, 7 min at 154 868 Hz).  Tags were
 available for 8 narwhals, 2 males and 6 females. There are two different
 datasets. The first one corresponds to the original dataset, shared by
 Blackwell et al. (2018), consisting of time-depth profiles, at one-second
 resolution, with an associated time, clicking state (where 1 = clicking, 0
 = non clicking), and depth for each second. The second dataset corresponds
 to the systematic random sampling of all clicking seconds in each record,
 where the length of the record determined the number of samples taken,
 within four predefined categories: 10, 100, 150, or 200 samples. Further
 data processing is done in https://github.com/MCarolinaMarques/Narwhal-echolocation-click-rates-article-analysis.git, where all of the information is processed and merged for each dataset.

title: Data for: Extensive cellular multi-tasking within Bacillus subtilis biofilms

description: Bacillus subtilis is a soil-dwelling bacterium that can form biofilms, or
 communities of cells surrounded by a self-produced extracellular matrix.
 In biofilms, genetically identical cells often exhibit heterogeneous
 transcriptional phenotypes, so that subpopulations of cells carry out
 essential yet costly cellular processes that allow the entire population
 to thrive. Surprisingly, the extent of phenotypic heterogeneity and the
 relationships between subpopulations of cells within biofilms of even in
 well-studied bacterial systems like B. subtilis remains largely unknown.
 To determine relationships between these subpopulations of cells,
 we created 182 strains containing pairwise combinations of fluorescent
 transcriptional reporters for the expression state of 14 different genes
 associated with potential cellular subpopulations. We determined the
 spatial organization of the expression of these genes within biofilms
 using confocal microscopy, which revealed that many reporters localized to
 distinct areas of the biofilm, some of which were co-localized. We used
 flow cytometry to quantify reporter coexpression, which revealed that many
 cells “multi-task,” simultaneously expressing two reporters. These data
 indicate that prior models describing B. subtilis cells as differentiating
 into specific cell types, each with a specific task or function, were
 oversimplified. Only a few subpopulations of cells, including surfactin
 and plipastatin producers, as well as sporulating and competent cells,
 appear to have distinct roles based on the set of genes examined here.
 These data will provide us with a framework with which to further study
 and make predictions about the roles of diverse cell phenotypes in B.
 subtilis biofilms.

title: Giant panda distribution ranges in the Liangshan Mountains

description: Comprehending the population trend and understanding the distribution
 range dynamics of species is necessary for global species protection.
 Recognizing what causes dynamic distribution change is crucial for
 identifying species’ environmental preferences and formulating protection
 policies. Here, we studied the rear-edge population of the flagship
 species, giant pandas (Ailuropoda melanoleuca), to 1) assess their
 population trend using their distribution patterns, 2) evaluate their
 distribution dynamics change from the 2nd (1988) to the 3rd (2001) surveys
 (2–3 Interval) and 3rd to the 4th (2013) survey (3–4 Interval) using a
 machine learning algorithm (The Extremely Gradient Boosting), and 3)
 decode model results to identify driver factors in the first known use of
 SHapley Additive exPlanations. Our results showed that the population
 trends in Liangshan Mountains were worst in the 2nd survey (k = 1.050),
 improved by the 3rd survey (k = 0.97), but got worse by the 4th survey (k
 = 0.996), which indicates a worrying population future. We found that
 precipitation had the most significant influence on distribution dynamics
 among several potential environmental factors, showing a negative
 correlation between precipitation and giant panda expansion. We recommend
 that more study is required to understand the micro-environment and animal
 distribution dynamics. We provide a fresh perspective on the dynamics of
 Giant Panda distribution, highlighting novel focal points for ecological
 research on this species. Our study offers theoretical underpinnings that
 could inform the formulation of more effective conservation policies.
 Also, we emphasize the uniqueness and importance of the Liangshan
 Mountains giant pandas as the rear-edge population, which is at a high
 risk of population extinction.

title: Reforestation of high elevation pines: Direct seeding success depends on seed source and sowing environment

description: Forest persistence in regions impacted by increasing water and temperature
 stress will depend upon species’ ability to either rapidly adjust to novel
 conditions or migrate to track ecological niches. Predicted, rapid climate
 change is likely to outpace the adaptive and migratory capacity of
 long-lived isolated tree species, and reforestation may be critical to
 species’ persistence. Facilitating persistence both within and beyond a
 species’ range requires identification of seed lots best adapted to the
 current and future conditions predicted with rapid climate change. We
 evaluate variation in emergent seedling performance that leads to
 differential survival among species and populations for three
 high-elevation five-needle pines. We paired a fully reciprocal field
 common garden experiment with a greenhouse common garden study to a)
 quantify variation in seedling emergence and functional traits, b) ask how
 functional traits affect performance under different establishment
 conditions, and c) evaluate whether trait and performance variation
 demonstrates local adaptation and plasticity. Among study species –
 limber, Great Basin bristlecone, and whitebark pines – we found divergence
 in emergence and functional traits, though soil moisture was the strongest
 driver of seedling emergence and abundance across all species. Generalist
 limber pine had a clear emergence advantage as well as traits associated
 with drought adaptation, while edaphic specialist bristlecone pine was
 characterized by low emergence yet high early survival once established.
 Despite evidence for edaphic specialization, soil characteristics alone
 did not explain bristlecone success. Across species, trait-environment
 relationships provided some evidence for local adaptation in
 drought-adapted traits, but we found no evidence of local adaptation in
 emergence or survival at this early life stage. For managers looking to
 promote persistence, sourcing seed from drier environments is likely to
 impart greater drought resistance into reforestation efforts through
 strategies such as greater root investment, increasing the probability of
 early seedling survival. This research demonstrates, through a rigorous
 reciprocal transplant experimental design, that it may be possible to
 select climate- and soil-appropriate seed sources for reforestation.
 However, planting success will ultimately rely on a suitable establishment
 environment, requiring careful consideration of interannual climate
 variability for management interventions in these climate- and
 disturbance-impacted tree species.

title: Data for: Evaluating motivation attributes and interaction elements in user adoption of voice intelligent assistant

description: Artificial intelligence (AI) has come to human life in various forms. As
 external activities decrease after COVID-19, people treat voice
 intelligent assistant (VIA) as a friend or secretary. This study suggests
 a conceptual model to identify the contributors to the continuance
 intention of VIA users. Data is collected from 262 users who use VIAs in
 their daily life for validating the model. The current research conducted
 partial least square structural equation modeling to validate the proposed
 model. The findings indicated that cabin fever syndrome significantly
 affects both utilitarian motivation and hedonic motivation. Loneliness in
 COVID-19 causes utilitarian motivation. The results verified that
 utilitarian motivation is the determinant of perceived usefulness,
 interaction, and voice attractiveness. The findings of the study figured
 out that hedonic motivation has a significant influence on interaction,
 parasocial interaction, and voice attractiveness. The analysis uncovered
 that interaction impacts satisfaction and continuance intention. The
 findings validated that voice attractiveness is significantly associated
 with satisfaction. Satisfaction is the determinant of continuance
 intention.

title: Data from: Brood size, food availability, and body size affects male care decisions and offspring performance

description: Parental care strategies do not only vary greatly across species, but also
 within species, there can be substantial between- and within-individual
 variation in parental care behaviour. To better understand the evolution
 of care strategies, it is crucial to determine how and when parents modify
 their behaviour in response to internal as well as environmental factors.
 Here, we investigated the effect of brood size, resource size and an
 individual's quality on care strategies of uniparental males and
 examined the downstream consequences on offspring performance in the
 burying beetle Nicrophorus vespilloides. Burying beetles breed on small
 vertebrate cadavers and, on average, males invest much less in care than
 females. Nevertheless, we found that uniparentally caring males were
 responsive to their social and non-social environment and adjusted the
 amount as well as the type of care to the size of the brood, the size of
 the cadaver and their own body size. Additionally, we show that the care
 strategies affected offspring performance. Specifically, males that cared
 longer had larger and more surviving larvae. Our results add to our
 understanding of plastic parenting strategies by showing that even the sex
 that provides less care can evolve a very flexible care behaviour.

title: Normalised absorbance ratios of IgG for myxoma and rabbit hemorrhagic disease viruses: Longitudinal dataset wild European rabbits

description: This study addresses the long-term dynamics of humoral immunity to two
 viral pathogens of the European rabbit, an endangered keystone species of
 major ecological relevance. Such studies are particularly challenging in
 free-ranging species, and a combination of longitudinal
 capture-mark-recapture and semi-quantitative serology was used to address
 this question. Over 600 normalised absorbance ratios of indirect ELISA,
 obtained from 505 individual rabbits in 7 populations over five years were
 analysed using linear mixed models. The results support a lifelong
 acquired humoral immunity to myxoma virus and rabbit hemorrhagic disease
 virus upon natural infection and suggest the presence of maternal immunity
 to the latter in wild juvenile rabbits. These results contribute to
 understanding the epidemiology of two viral diseases threatening this
 keystone species and assist in developing conservation programs.

title: Dataset: Corridor quality buffers extinction under extreme droughts in experimental metapopulations

description: Corridors with good-quality habitats maintain the spatial dynamics of
 metapopulations by promoting dispersal between habitat patches,
 potentially buffering populations and communities against continued global
 change. However, this function is threatened by habitats becoming
 increasingly fragmented, and habitat matrices becoming increasingly
 inhospitable, potentially reducing the resilience and persistence of
 populations. Yet, we lack a clear understanding of how reduced corridor
 quality interacts with rates of environmental change to destabilise
 populations. Using laboratory microcosms containing metapopulations of the
 Collembola Folsomia candida, we investigate the impact of corridor quality
 on metapopulation persistence under a range of simulated droughts, a key
 stressor for this species. We manipulated both drought severity and the
 number of patches affected by drought across landscapes connected by
 either good or poor-quality corridors. We measured the time of
 metapopulation extinction, the maximum rate of metapopulation decline, and
 the variability of abundance among patches as criteria to evaluate the
 persistence ability of metapopulations. We show that whilst drought
 severity negatively influenced the time of metapopulation extinction and
 the increase in drought patches caused metapopulation decline, these
 results were mitigated by good quality corridors, which increased
 metapopulation persistence time and decreased both how fast
 metapopulations declined and the inter-patch variability in abundances.
 Our results suggest that enhancing corridor quality can increase the
 persistence of metapopulations, increasing the time available for
 conservation actions to take effect, and/or for species to adapt or move
 in the face of continued stress. Given that fragmentation increases the
 isolation of habitats, improving the quality of habitat corridors may
 provide a useful strategy to enhance the resistance of spatially
 structured populations.

 up at week 1 and then sampled weekly by image analysis processes. The

title: Differentiation of rhizosphere fungal assemblages by host ploidy level in mixed-ploidy Larrea tridentata populations

description: Polyploidy—whole genome duplication—is common in plants. Studies over the
 last several decades have documented numerous mixed-ploidy populations.
 Whether arising via recurrent whole genome duplication events within a
 population, or from secondary contact, the persistence of mixed
 populations is possible by niche differentiation. Specifically, one
 mechanism facilitating ploidy co-occurrence is microbially-mediated niche
 differentiation (MMND), wherein cytotypes occupy different niches via
 interactions with different sets of microbes. Inherently cryptic, MMND is
 underexplored in polyploid plant populations. Here, we search for evidence
 of MMND in creosotebush (Larrea tridentata), a dominant desert shrub of
 the southwestern U.S. and northern Mexico. We sequenced root-associated
 fungal taxa in soil diploid, autotetraploid, and autohexaploid plants
 growing in two naturally-occurring mixed-cytotype populations. Within
 populations, we found substantial fungal assemblage overlap across host
 plant cytotypes. However, using indicator species analysis, we identified
 some fungi that are differentiated by host plant cytotype, satisfying a
 precondition for MMND. Future study is needed to determine the degree of
 niche differentiation conferred, if any, and whether the identified fungi
 play a role in the long-term persistence of multiple cytotypes within
 populations.
description: These data come from root-associated soils from 50+
 <em>Larrea</em> <em>tridentata</em> of various
 ploidies collected in mixed-ploidy populations. DNA was extracted and
 fungal ITS amplifed and sequenced. The data has been cleaned to be a list
 of fungal OTUs and the scripts further filter out none fungal
 OTUs.
