title: Data from: Fire increases drought vulnerability of Quercus alba juveniles by altering forest microclimate and nitrogen availability

description: 1. Shifts in rainfall patterns due to climate change are expected to
 increase drought stress and mortality in forests. Natural and
 anthropogenic fire regimes are also changing, highlighting the need to
 understand the interactive effects of fire and drought on tree
 ecophysiological response and growth. 2. Using rainout shelters, we
 imposed summer drought on natural and planted populations of Quercus alba
 juveniles located in periodically burned and unburned sites in Shawnee
 National Forest, IL, USA. A subset of planted juveniles was clipped to
 simulate topkill. We measured predawn leaf water potential (Ψpd), leaf gas
 exchange (Amax, gmax), and relative growth rate (RGR) across treatments to
 test two hypotheses: (H1) fire reduces juvenile drought stress by
 improving water relations through increased root to shoot ratios after
 topkill, or (H2) fire exacerbates juvenile drought stress by promoting a
 warmer, drier microclimate or amplifying drought-induced nitrogen (N)
 limitation. 3. Burned stands had higher vapor pressure deficits and 13%
 lower soil inorganic N availability than unburned stands. Rainout shelters
 reduced soil moisture (0 – 45 cm) by 10 – 24% relative to ambient
 conditions. Consistent with H2, small, natural resprouts in burned stands
 experienced greater drought stress than unburned juveniles, with a 7%
 decrease in leaf nitrogen content (LNC), a 21-29% reduction in Amax and
 gmax, and a 41% reduction in RGR under drought. Drought effects on
 unburned juveniles, in contrast, were limited to a 5% reduction in LNC and
 a neutral to positive effect on leaf gas exchange and RGR. Large natural
 juveniles were largely unaffected by drought. Recent resprouts (i.e.,
 clipped, planted juveniles) experienced less drought stress than unclipped
 juveniles, providing partial support for H1. 4. Collectively, these
 results suggest that resprouting after fire can temporarily improve leaf
 water relations until root to shoot ratios re-equilibrate. In contrast,
 fire can exacerbate drought-driven declines in the growth of small
 juveniles by both promoting a warmer, drier microclimate and intensifying
 N limitation. Our results suggest that despite the high drought tolerance
 of Quercus spp., fire-driven changes to local microclimate and resource
 conditions could limit tree recruitment under future scenarios of rainfall
 variability.

title: Data from: Perceived impact of community kitchens on the food security of Syrian refugees and kitchen workers in Lebanon: Qualitative evidence in a displacement context

description: Community kitchens (CKs) have been recommended as public health strategies
 with social and nutritional health benefits for low-income participants
 and their families in different settings. The benefit of CKs in improving
 the food security status of participants in the context of conflict and
 displacement is less conclusive. This study aimed to qualitatively explore
 the impact of CKs on the food security status of community kitchen workers
 (CWs) and Syrian refugee (SR) families in Lebanon. An exploratory
 qualitative descriptive approach was adopted. Focus group discussions were
 conducted with 15 CWs and 49 SRs, and transcripts were analyzed
 thematically. Emerging themes included: motivation to join the CKs (CWs
 only), perception towards CKs, impact of these CKs, and their
 sustainability (both groups). Motivating factors for CWs included
 financial, internal and societal drivers, and the favorable type of work
 in kitchens. The perception towards CKs was overall positive among CWs and
 SR beneficiaries. Both groups reported the positive impact of CKs on their
 food security and financial status, which in turn affected positively
 their psychological health. At the social level, CWs indicated that the
 kitchen’s friendly atmosphere increased social cohesion and companionship
 between Syrians and Lebanese within the kitchen. In addition, CWs reported
 increased sense of empathy towards SRs benefiting from the CK services.
 According to study participants, the positive impact of the CKs was almost
 completely reversed when their operation and services were interrupted for
 two months. Both CWs and SRs identified facilitators and barriers that can
 affect the sustainability of the kitchens, including financial and
 entrepreneurial skills. In conclusion, findings from this study highlight
 that CKs can be promising programs to improve the food security and
 livelihoods of participants, while also increasing social cohesion and
 integration of refugees within host communities in protracted crisis
 contexts.

title: Data from: Determinants of hierarchical genetic structure in Atlantic salmon populations: environmental factors vs. anthropogenic influences

description: Disentangling the effects of natural environmental features and
 anthropogenic factors on the genetic structure of endangered populations
 is an important challenge for conservation biology. Here we investigated
 the combined influences of major environmental features and stocking with
 non-native fish on the genetic structure and local adaptation of Atlantic
 salmon (Salmo salar) populations. We used 17 microsatellite loci to
 genotype 975 individuals originating from 34 French rivers. Bayesian
 analyses revealed a hierarchical genetic structure into five
 geographically distinct clusters. Coastal distance, geological substrate
 and river length were strong predictors of population structure. Gene flow
 was higher among rivers with similar geologies, suggesting local
 adaptation to geological substrate. The effect of river length was mainly
 due to one highly differentiated population that has the farthest spawning
 grounds off the river mouth (up to 900 km) and the largest fish,
 suggesting local adaptation to river length. We detected high levels of
 admixture in stocked populations but also in neighboring ones, implying
 large scale impacts of stocking through dispersal of
 non-native-individuals. However, we found relatively few admixed
 individuals suggesting a lower fitness of stocked fish and/or some
 reproductive isolation between wild and stocked individuals. When
 excluding stocked populations, genetic structure increased as did its
 correlation with environmental factors. This study overall indicates that
 geological substrate and river length are major environmental factors
 influencing gene flow and potential local adaptation among Atlantic salmon
 populations but that stocking with non-native individuals may ultimately
 disrupt these natural patterns of gene flow among locally adapted
 populations.

title: Data from: Hot spots of genetic diversity descended from multiple Pleistocene refugia in an alpine ungulate

description: Species that inhabit naturally fragmented environments are expected to be
 spatially structured and exhibit reduced genetic diversity at the
 periphery of their range. Patterns of differentiation may also reflect
 historical processes such as recolonization from glacial refugia. We
 examined the relative importance of these factors in shaping the spatial
 patterns of genetic differentiation across the range of an alpine
 specialist, the North American mountain goat (Oreamnos americanus).
 Contrary to fossil evidence which suggests a single southern refugium, we
 detected evidence for additional refugia in northern British Columbia and
 the Alaskan coast using both mitochondrial and microsatellite DNA. A core
 area of elevated genetic diversity characterized both regions, and
 molecular dating suggested a recent Pleistocene split was followed by
 demographic expansion. Across their range, mountain goats were highly
 genetically structured and displayed the expected pattern of declining
 diversity towards the periphery. Gene flow was high within contiguous
 mountain ranges, but cross-assignments paradoxically suggest that
 long-distance contemporary dispersal movements are not uncommon. These
 results improve our understanding of how historical vicariance and
 contemporary fragmentation influence population differentiation, and have
 implications for conserving the adaptive potential of alpine populations
 and habitat.

title: Data from: Managing conflict between bats and humans: the response of soprano pipistrelles (Pipistrellus pygmaeus) to exclusion from roosts in houses

description: Conflict can arise when bats roost in human dwellings and householders are
 affected adversely by their presence. In the United Kingdom, the exclusion
 of bats from roosts can be licensed under exceptional circumstances to
 alleviate conflict, but the fate of excluded bats and the impact on their
 survival and reproduction is not well understood. Using radio-tracking, we
 investigated the effects of exclusion on the soprano pipistrelle
 Pipistrellus pygmaeus, a species that commonly roosts in buildings in
 Europe. Exclusions were performed under licence at five roosts in England
 in spring, when females were in the early stages of pregnancy. Following
 exclusion, all bats found alternative roosts and colonies congregated in
 nearby known roosts that had been used by radio-tagged bats prior to
 exclusion. We found no difference in roosting behaviour before and after
 exclusion. Both the frequency of roost switching and the type of roosts
 used by bats remained unchanged. We also found no change in foraging
 behaviour. Bats foraged in the same areas, travelled similar distances to
 reach foraging areas and showed similar patterns of habitat selection
 before and after exclusion. Population modelling suggested that any
 reduction in survival following exclusion could have a negative impact on
 population growth, whereas a reduction in productivity would have less
 effect. While the number of soprano pipistrelle exclusions currently
 licensed each year is likely to have little effect on local populations,
 the cumulative impacts of licensing the destruction of large numbers of
 roosts may be of concern.

title: Data from: Influence of early reproductive success on longevity and late reproductive success in an alpine ungulate

description: The life-history theories of aging predict lifetime trade-offs between
 early reproductive allocation and late-life survival, reproduction, or
 both components of fitness. Recent studies in wild populations have found
 evidence for these early-late life trade-offs, but rarely have they been
 found across multiple traits while exploring the additional effects of
 variation in environmental conditions and individual quality. Benefiting
 from longitudinal data on adult female mountain goats (Oreamnos
 americanus), we investigated the influence of age at first reproduction
 (AFR) and early reproductive success (ERS) on longevity, late reproductive
 success, and senescence rates while accounting for the influence of natal
 environmental conditions and individual quality. Contrary to predictions,
 we did not find evidence for early-late life trade-offs. Instead, an
 earlier AFR and a greater ERS had positive but weak direct effects on late
 reproductive success. Natal population density, however, was the strongest
 determinant of all life-history traits, having a direct negative effect on
 female longevity, late reproductive success, AFR, and ERS. Although natal
 density reduced the probability of annual reproduction and annual survival
 during adulthood, higher allocation to reproduction in early life and
 poorer natal conditions did not lead to accelerated rates of senescence
 during adulthood. The results of this investigation provide an integrated
 picture of early-late life trade-offs, underscoring the importance of
 accounting for environmental conditions because of their potentially
 strong implications for population dynamics.

title: Data from: Herbivores control effects of algal species richness on community biomass and stability in a laboratory microcosm experiment

description: Hundreds of studies that have explored how biodiversity affects the
 productivity and stability of ecosystems have produced a consensus that
 communities composed of more species tend to have higher biomass that is
 more stable through time. However, the majority of this work stems from
 studies performed using highly simplified food webs, often composed of
 just primary producers competing for inorganic resources in the absence of
 trophic interactions. When studies have incorporated trophic interactions,
 diversity-function relationships have been more variable, leaving open the
 question of how biodiversity affects the functioning of ecosystems with
 more trophic levels. Here we report the results of a laboratory experiment
 that used freshwater microcosms to test for effects of algal diversity
 (one or four species) on community biomass and temporal variability in the
 presence and absence of two different herbivore species (cladocerans
 Ceriodaphnia dubia and Daphnia pulex). When no herbivores were present, we
 found the classic pattern observed in hundreds of other studies – as
 species richness of algae increased, algal biomass increased, and the
 temporal variation in biomass decreased. This pattern was retained when
 one of the herbivores (C. dubia) was present. Ceriodaphnia dubia exhibited
 weak and non-selective grazing on the focal algae, leaving the effect of
 diversity on biomass and variability essentially intact. In contrast, D.
 pulex exhibited strong and selective grazing in algal polycultures that
 qualitatively altered both diversity–function relationships. As algal
 richness increased, total algal biomass decreased and variation through
 time increased. These changes were coupled with larger and less variable
 populations of D. pulex. Our results show that herbivory leads to a richer
 array of diversity–function relationships than often observed in studies
 focused on just one trophic level, and suggests trophic interactions
 should be given more attention in work that seeks to determine how
 biodiversity impacts the functioning of ecosystems.

title: Data from: Mass seasonal bioflows of high-flying insect migrants

description: Migrating animals have an impact on ecosystems directly via influxes of
 predators, prey, and competitors and indirectly by vectoring nutrients,
 energy, and pathogens. Although linkages between vertebrate movements and
 ecosystem processes have been established, the effects of mass insect
 “bioflows” have not been described. We quantified biomass flux over the
 southern United Kingdom for high-flying (&gt;150 meters) insects and
 show that ~3.5 trillion insects (3200 tons of biomass) migrate above the
 region annually. These flows are not randomly directed in insects larger
 than 10 milligrams, which exploit seasonally beneficial tailwinds. Large
 seasonal differences in the southward versus northward transfer of biomass
 occur in some years, although flows were balanced over the 10-year period.
 Our long-term study reveals a major transport process with implications
 for ecosystem services, processes, and biogeochemistry.

title: Data from: Escape distance in ground-nesting birds differs with individual level of camouflage

description: Camouflage is one of the most widespread antipredator strategies in the
 animal kingdom, yet no animal can match its background perfectly in a
 complex environment. Therefore, selection should favor individuals that
 use information on how effective their camouflage is in their immediate
 habitat when responding to an approaching threat. In a field study of
 African ground-nesting birds (plovers, coursers, and nightjars), we tested
 the hypothesis that individuals adaptively modulate their escape behavior
 in relation to their degree of background matching. We used digital
 imaging and models of predator vision to quantify differences in color,
 luminance, and pattern between eggs and their background, as well as the
 plumage of incubating adult nightjars. We found that plovers and coursers
 showed greater escape distances when their eggs were a poorer pattern
 match to the background. Nightjars sit on their eggs until a potential
 threat is nearby, and, correspondingly, they showed greater escape
 distances when the pattern and color match of the incubating adult's
 plumage-rather than its eggs-was a poorer match to the background.
 Finally, escape distances were shorter in the middle of the day,
 suggesting that escape behavior is mediated by both camouflage and
 thermoregulation.
