title: Data from: Tailored flower strips promote natural enemy biodiversity and pest control in potato crops

description: 1. Sown flower strips are increasingly implemented within agri-environment
 schemes (AES) to increase functional biodiversity and ecosystem services
 such as pollination or natural pest control, but their effectiveness in
 achieving these goals remains poorly studied. 2. We tested the performance
 of experimentally sown annual flower strips specifically designed to
 promote natural enemies of aphids and their pest control services
 (tailored flower strips) in adjacent potato crops (n=8) compared to
 control fields (n=10). Flower strips consisted of 11 plant species
 providing abundant floral and extra-floral resources. 3. The abundance of
 key natural enemies of aphids (hoverflies, lacewings and ladybirds) and
 hoverfly species richness was greatly enhanced in tailored flower strips
 compared to potato control strips. This resulted in an average increase in
 the number of eggs deposited by hoverflies and lacewings by 127 % and 48
 %, respectively, and a reduction in the number of aphids by 75 % in
 adjacent potato crops. 4. Synthesis and applications. We conclude that
 tailored flower strips can be an effective agri-environmental measure to
 enhance natural enemies and aphid control in nearby crops. Indeed,
 tailored flower strips may help to reduce insecticide input in potato
 production as they significantly decrease the probability that action
 thresholds are reached. Promoting natural enemy abundance and diversity,
 as observed for hoverflies, may increase the stability of pest control and
 provide additional benefits to agro-ecosystems in terms of natural enemy
 conservation. We thus recommend establishing tailored flower strips as a
 promising management option to reconcile the objectives of ecological
 intensification and biodiversity conservation.

title: Data from: Growth profiling, kinetics and substrate utilization of low-cost dairy waste for production of β-cryptoxanthin by Kocuria marina DAGII

description: Dairy industry produces enormous amount of cheese whey compromising of
 major milk nutrients but remains unutilized all over the globe. The
 present study investigates the production of β-Cryptoxanthin (β-CRX) by
 Kocuria marina DAGII using cheese whey as substrate. Response surface
 methodology (RSM) and artificial neural network (ANN) was implemented to
 obtain the maximum β-CRX yield. Significant factors viz. yeast extract,
 peptone, cheese whey and initial pH were the input variables in both the
 optimizing studies and β-CRX yield and biomass were taken as output
 variables. The ANN topology of 4-9-2 was found to be optimum when trained
 with feed-forward back propagation algorithm. Experimental values of β-CRX
 yield (17.14 mg/L) and biomass (5.35 g/L) were compared and ANN predicted
 (16.99 mg/L and 5.33 g/L respectively) values were found to be more
 accurate compared to RSM predicted values (16.95 mg/L and 5.23 g/L
 respectively). Detailed kinetic analysis of cellular growth, substrate
 consumption and product formation revealed that growth inhibition took
 place at substrate concentrations higher than 12%(v/v) of cheese whey. Han
 and Levenspiel model was the best fitted substrate inhibition model that
 described the cell growth in cheese whey with a R2 and MSE of 0.9982 and
 0.00477%, respectively. The potential importance of this study lies in the
 development, optimization, modelling and characterization of a suitable
 cheese whey supplemented medium for increased β-CRX production.

title: Data from: Cryptic recombination in the ever-young sex chromosomes of Hylid frogs

description: Sex chromosomes are expected to evolve suppressed recombination, which
 leads to degeneration of the Y and heteromorphism between the X and Y.
 Some sex chromosomes remain homomorphic, however, and the factors that
 prevent degeneration of the Y in these cases are not understood. The
 homomorphic sex chromosomes of the European tree frogs (Hyla spp.) present
 an interesting paradox. Recombination in males has never been observed in
 crossing experiments, but molecular data are suggestive of occasional
 recombination between the X and Y. The hypothesis that these sex
 chromosomes recombine has not been tested statistically, however, nor has
 the XY recombination rate been estimated. Here we use Approximate Bayesian
 Computation coupled with coalescent simulations of sex chromosomes to
 quantify X-Y recombination rate from existent data. We find that
 microsatellite data from H. arborea, H. intermedia, and H. molleri support
 a recombination rate between X and Y that is significantly different from
 zero. We estimate that rate to be approximately 105 times smaller than
 that between X chromosomes. Our findings support the notion that very low
 recombination rate may be sufficient to maintain homomorphism in sex
 chromosomes.

title: Data from: Genetic structure, spatial organization, and dispersal in two populations of bat-eared foxes

description: We incorporated radio-telemetry data with genetic analysis of bat-eared
 foxes (Otocyon megalotis) from individuals in 32 different groups to
 examine relatedness and spatial organization in two populations in South
 Africa that differed in density, home-range sizes, and group sizes. Kin
 clustering occurred only for female dyads in the high-density population.
 Relatedness was negatively correlated with distance only for female dyads
 in the high-density population, and for male and mixed-sex dyads in the
 low-density population. Home-range overlap of neighboring female dyads was
 significantly greater in the high compared to low-density population,
 whereas overlap within other dyads was similar between populations. Amount
 of home-range overlap between neighbors was positively correlated with
 genetic relatedness for all dyad-site combinations, except for female and
 male dyads in the low-density population. Foxes from all age and sex
 classes dispersed, although females (mostly adults) dispersed farther than
 males. Yearlings dispersed later in the high-density population, and
 overall exhibited a male-biased dispersal pattern. Our results indicated
 that genetic structure within populations of bat-eared foxes was
 sex-biased, and was interrelated to density and group sizes, as well as
 sex-biases in philopatry and dispersal distances. We conclude that a
 combination of male-biased dispersal rates, adult dispersals, and
 sex-biased dispersal distances likely helped to facilitate inbreeding
 avoidance in this evolutionarily unique species of Canidae.

title: Data from: Insect pollination is at least as important for marketable crop yield as plant quality in a seed crop

description: The sustainability of agriculture can be improved by integrating
 management of ecosystem services, such as insect pollination, into farming
 practices. However, large‐scale adoption of ecosystem services‐based
 practices in agriculture is lacking, possibly because growers undervalue
 the benefits of ecosystem services compared to those of conventional
 management practices. Here we show that, under representative real‐world
 conditions, pollination and plant quality made similar contributions to
 marketable seed yield of hybrid leek (Allium porrum). Relative to the
 median, a 25% improvement of plant quality and pollination increased crop
 value by an estimated $18 007 and $17 174 ha−1 respectively. Across five
 crop lines, bumblebees delivered most pollination services, while other
 wild pollinator groups made less frequent but nevertheless substantial
 contributions. Honeybees actively managed for pollination services did not
 make significant contributions. Our results show that wild pollinators are
 an undervalued agricultural input and managing for enhancing pollinators
 makes sense economically in high‐revenue insect‐pollinated cropping
 systems.

title: Data from: The role of plant-soil feedbacks in stabilizing a reindeer-induced vegetation shift in subarctic tundra

description: 1.Herbivory can drive vegetation into different states of productivity and
 community composition, and these changes may be stable over time due to
 historical contingency effects. Interactions with abiotic and biotic soil
 components can contribute to such long‐term legacies in plant communities
 through stabilizing positive feedbacks. 2.We studied the role of
 plant‐soil feedbacks in maintaining vegetation changes caused by
 historical (~1350‐1900 AD) reindeer herding in northern Sweden. These
 historical milking grounds (HMGs) consist of meadow plant communities
 formed in naturally nutrient poor heath or naturally nutrient rich
 shrub‐dominated vegetation, and are still clearly visible in the
 landscape, a century after active use ceased. 3.We selected two phytometer
 species: the forb Potentilla crantzii as representative of HMG vegetation,
 and the dwarf shrub Betula nana, as representative of control vegetation.
 We grew both species under glasshouse conditions on soils derived from
 replicated HMG and paired control plots, using live soils and sterilized
 (γ‐radiation)‐inoculated soils, to separate between biotic and abiotic
 soil effects. 4.A net negative plant‐soil feedback for B. nana biomass in
 its home (i.e., control) soil and a net positive feedback for P. crantzii
 in its home (i.e., HMG) soil in heath habitat was partly driven by the
 soil biotic community. However, abiotic differences in mineral nitrogen
 (N) concentrations between control and HMG soils were a stronger driver of
 differences in plant growth. Positive feedbacks maintaining a high mineral
 nutrient availability are thus important, especially in nutrient poor
 habitats. 5.The positive plant responses to higher soil mineral N
 concentrations, combined with positive biotic plant‐soil feedbacks, might
 shift the competitive balance in favour of typical HMG plant species,
 thereby contributing to stability of HMG plant communities. Our data
 indicate that herbivore‐driven changes in the interactions between plants
 and both biotic and abiotic components of the soil persist over long
 temporal scales.

title: Data from: Population connectivity and phylogeography of a coastal fish, Atractoscion aequidens (Sciaenidae), across the Benguela Current region: evidence of an ancient vicariant event.

description: Contemporary patterns of genetic diversity and population connectivity
 within species can be influenced by both historical and contemporary
 barriers to gene flow. In the marine environment, present day
 oceanographic features such as currents, fronts and upwelling systems can
 influence dispersal of eggs/larvae and/juveniles/adults, shaping
 population substructuring. The Benguela Current system in the southeastern
 Atlantic is one of the oldest upwelling systems in the world, and provides
 a unique opportunity to investigate the relative influence of contemporary
 and historical mechanisms shaping the evolutionary history of
 warm-temperate fish species. Using the genetic variation in the
 mitochondrial DNA Control Region and eight nuclear microsatellite DNA
 loci, we identified the presence of two highly divergent populations in a
 vagile and warm-temperate fish species, Atractoscion aequidens, across the
 Benguela region. The geographical distributions of the two populations, on
 either side of the perennial upwelling cell, suggest a strong correlation
 between the oceanographic features of the system and the breakdown of gene
 flow within this species. Genetic divergence (mtDNA φST = 0.902,
 microsatellite FST = 0.055: probability of genetic homogeneity for either
 marker = p&lt;0.001), absence of migrants (less than 1% per
 generation) between populations and coalescent estimates of time since
 most recent common ancestor suggest that the establishment of the main
 oceanographic features of the system (2 million years ago), particularly
 the strengthening and position of the perennial upwelling cell, is the
 most likely mechanism behind the observed isolation. Concordance between
 mitochondrial and nuclear genetic markers indicates that isolation and
 divergence of the northern and southern Benguela populations of A.
 aequidens occurred deep in the past and has continued to the present day.
 These findings suggest that the Benguela Current system may constitute an
 ancient and impermeable barrier to gene flow for warm-temperate fish
 species.

title: Data from: Effects of food restriction across stages of juvenile and early adult development on body weight, survival, and adult life history

description: Organisms have to allocate limited resources among multiple life-history
 traits, which can result in physiological trade-offs, and variation in
 environmental conditions experienced during ontogeny can influence
 reproduction later in life. Food restriction may lead to an adaptive
 reallocation of the limited resources among traits as a phenotypically
 plastic adjustment, or it can act as an overall constraint with
 detrimental effects throughout reproductive life. In this study, we
 investigated experimentally the effects of food restriction during
 different stages of the juvenile and early adult development on body
 weight, survival and reproductive success in females and males of the
 European earwig Forficula auricularia. Individuals either received limited
 or unlimited access to food across three different stages of development
 (fully crossed) allowing us to identify sensitive periods during
 development and to test both additive and interactive effects of food
 limitation across stages on development and reproduction. Food restriction
 during the early and late juvenile stage had additive negative effects on
 juvenile survival and adult body weight. With regard to reproductive
 success of females which produce up to two clutches in their lifetime,
 restriction specifically in the late juvenile stage led to smaller first
 and second clutch size, lower probability of second clutch production and
 reduced hatching success in the second clutch. Reproductive success of
 females was not significantly affected when their male mates experienced
 food restriction during their development. Our findings in general support
 the ‘silver-spoon’ hypothesis in that food restriction during juvenile
 development poses constraints on development and reproduction throughout
 life.

title: Data from: Fundamental and realized feeding niche breadths of sexual and asexual stick insects

description: The factors contributing to the maintenance of sex over asexuality in
 natural populations remain unclear. Ecological divergences between sexual
 and asexual lineages could help to maintain reproductive polymorphisms, at
 least transiently, but the consequences of asexuality for the evolution of
 ecological niches are unknown. Here, we investigated how niche breadths
 change in transitions from sexual reproduction to asexuality. We used host
 plant ranges as a proxy to compare the realized feeding niche breadths of
 five independently derived asexual Timema stick insects’ species and their
 sexual relatives at both the species and population levels. Asexual
 species had a systematically narrower realized niche than sexual species,
 though this pattern was not apparent at the population level. To
 investigate how the narrower realized niches of asexual species arise, we
 performed feeding experiments to estimate fundamental niche breadths but
 found no systematic differences between reproductive modes. The narrow
 realized niches found in asexual species are therefore likely a
 consequence of biotic interactions such as predation or competition, that
 constrain realized niche size in asexuals more strongly than in sexuals.

title: Data from: Long-term antagonistic effect of increased precipitation and nitrogen addition on soil respiration in a semiarid steppe

description: Changes in water and nitrogen (N) availability due to climate change and
 atmospheric N deposition could have significant effects on soil
 respiration, a major pathway of carbon (C) loss from terrestrial
 ecosystems. A manipulative experiment simulating increased precipitation
 and atmospheric N deposition has been conducted for 9 years (2005–2013) in
 a semiarid grassland in Mongolian Plateau, China. Increased precipitation
 and N addition interactively affect soil respiration through the 9 years.
 The interactions demonstrated that N addition weakened the
 precipitation-induced stimulation of soil respiration, whereas increased
 precipitation exacerbated the negative impacts of N addition. The main
 effects of increased precipitation and N addition treatment on soil
 respiration were 15.8% stimulated and 14.2% suppressed, respectively.
 Moreover, a declining pattern and 2-year oscillation were observed for
 soil respiration response to N addition under increased precipitation. The
 dependence of soil respiration upon gross primary productivity and soil
 moisture, but not soil temperature, suggests that resources C substrate
 supply and water availability are more important than temperature in
 regulating interannual variations of soil C release in semiarid grassland
 ecosystems. The findings indicate that atmospheric N deposition may have
 the potential to mitigate soil C loss induced by increased precipitation,
 and highlight that long-term and multi-factor global change studies are
 critical for predicting the general patterns of terrestrial C cycling in
 response to global change in the future.

title: Data from: Resurrected “ancient” Daphnia genotypes show reduced thermal stress tolerance compared to modern descendants

description: Understanding how populations adapt to rising temperatures has been a
 challenge in ecology. Research often evaluates multiple populations to
 test whether local adaptation to temperature regimes is occurring.
 Space-for-time substitutions are common, as temporal constraints limit our
 ability to observe evolutionary responses. We employed a resurrection
 ecology approach to understand how thermal tolerance has changed in a
 Daphnia pulicaria population over time. Temperatures experienced by the
 oldest genotypes were considerably lower than the youngest. We
 hypothesized clones were adapted to the thermal regimes of their
 respective time periods. We performed two thermal shock experiments that
 varied in length of heat exposure. Overall trends revealed that younger
 genotypes exhibited higher thermal tolerance than older genotypes; heat
 shock protein (hsp70) expression increased with temperature and varied
 among genotypes, but not across time periods. Our results indicate
 temperature may have been a selective factor on this population, although
 the observed responses may be a function of multifarious selection. Prior
 work found striking changes in population genetic structure, and in other
 traits that were strongly correlated with anthropogenic changes.
 Resurrection ecology approaches should help our understanding of
 interactive effects of anthropogenic alterations to temperature and other
 stressors on the evolutionary fate of natural populations.
