title: Data from: Environmentally dependent host-pathogen and vector-pathogen interactions in the barley yellow dwarf virus pathosystem

description: 1. Understanding environmentally dependent variation in interspecific
 interactions is needed for evaluating how agroecosystems respond to
 abiotic stressors, including climate change. Both biotic and abiotic
 conditions shape crop responses to stress events, but interactions between
 environmental conditions and insect borne plant pathogens remain poorly
 understood. 2. We tested the hypothesis that drought stress, as applied by
 experimental water deprivation, drives conditional outcomes in
 host–pathogen and host–vector interactions using a cereal–aphid–virus
 association and greenhouse experiments. 3. Under conditions of ample water
 supply, infection of wheat plants with Barley yellow dwarf virus (BYDV)
 resulted in reduced above-ground growth, seed set, seed yields and seed
 germination compared with plants exposed only to non-infected
 (non-viruliferous) aphids or control plants not subjected to aphid
 infestation. However, when water was chronically limiting, infection with
 Barley yellow dwarf virus did not significantly affect plant performance.
 4. When wheat was subjected to acute drought stress, plants infected with
 Barley yellow dwarf virus surpassed both control plants and plants exposed
 to non-infected aphids in all measured performance traits. 5. Feeding
 experiments with aphid vectors (Rhopalosiphum padi) and subsequent life
 table analysis revealed that aphid fecundity improved by 47% when feeding
 on Barley yellow dwarf virus-infected plants when water inputs were
 chronically low. However, when plants received ample water, aphid
 fecundity was enhanced by only 23% from feeding on BYDV-infected plants.
 6. Synthesis and applications. Collectively, our experiments suggest that
 wheat– Barley yellow dwarf virus interactions shift along gradients of
 water stress severity and duration. When Barley yellow dwarf virus
 infection preceded water deprivation, plant performance was not reduced
 from virus infection, and infected plants recovered from severe stress
 events more readily than non-infected plants. However, vector–pathogen
 mutualism resulting in enhanced reproduction of aphids on virus-infected
 plants is likely to amplify direct plant injury from herbivory in the
 field. Our findings indicate that during periods of drought, management of
 Barley yellow dwarf virus infection may not be needed and infection could
 benefit wheat under conditions of acute water stress.

title: Data from: Endemic chronic wasting disease causes mule deer population decline in Wyoming

description: Chronic wasting disease (CWD) is a fatal transmissible spongiform
 encephalopathy affecting white-tailed deer (Odocoileus virginianus), mule
 deer (Odocoileus hemionus), Rocky Mountain elk (Cervus elaphus nelsoni),
 and moose (Alces alces shirasi) in North America. In southeastern Wyoming
 average annual CWD prevalence in mule deer exceeds 20% and appears to
 contribute to regional population declines. We determined the effect of
 CWD on mule deer demography using age-specific, female-only, CWD
 transition matrix models to estimate the population growth rate (λ). Mule
 deer were captured from 2010–2014 in southern Converse County Wyoming,
 USA. Captured adult (≥ 1.5 years old) deer were tested ante-mortem for CWD
 using tonsil biopsies and monitored using radio telemetry. Mean annual
 survival rates of CWD-negative and CWD-positive deer were 0.76 and 0.32,
 respectively. Pregnancy and fawn recruitment were not observed to be
 influenced by CWD. We estimated λ = 0.79, indicating an annual population
 decline of 21% under current CWD prevalence levels. A model derived from
 the demography of only CWD-negative individuals yielded; λ = 1.00,
 indicating a stable population if CWD were absent. These findings support
 CWD as a significant contributor to mule deer population decline. Chronic
 wasting disease is difficult or impossible to eradicate with current
 tools, given significant environmental contamination, and at present our
 best recommendation for control of this disease is to minimize spread to
 new areas and naïve cervid populations.

title: Data from: The effects of dietary macronutrients on flight ability, energetics, and fuel metabolism of yellow-rumped warblers Setophaga coronata

description: The catabolism of protein from organs and muscles during migratory flight
 is necessary to produce glucose, key metabolic intermediates, and water,
 but may have negative effects on flight range and refueling at stopovers.
 We tested the hypothesis, suggested by previous studies, that birds that
 eat high-protein insect diets use more protein for fuel in flight than
 those that eat high-carbohydrate fruits. First, we fed migratory
 yellow-rumped warblers synthetic fruit or mixed insect/fruit diets, and
 measured metabolic rates and fuel mixture under basal conditions and
 during exercise in a hop/hover wheel respirometer. Birds eating the fruit
 diet had greater plasma triglyceride and non-esterified fatty acid
 concentrations, and the higher protein mixed diet increased plasma uric
 acid only during feeding. Diet did not affect metabolic rates or the fuel
 mixture under resting or exercise conditions. We then fed yellow-rumped
 warblers synthetic diets that differed only in the relative proportion of
 carbohydrate and protein (60:15 versus 15:60 as % dry mass) and tested
 them in wind tunnel flights lasting up to six hours. Birds fed the high
 carbohydrate diet became heavier and fatter than when fed the high protein
 diet. Plasma uric acid concentration was increased and plasma phospholipid
 concentration was decreased by the high protein diet in the pre-flight
 state (after a 3 h fast), but diet only affected plasma phospholipids
 during flight (lower in high protein birds). Neither diet nor amount of
 body fat affected the rate of loss of lean mass or fat during flight.
 Inter-individual or seasonal differences in diet do not appear to
 influence the amount of protein catabolized during endurance flight.
 However, birds fed the high carbohydrate diet had greater voluntary flight
 duration, independent of body fatness, suggesting that there may be other
 performance benefits of high carbohydrate diets for migratory birds.

title: Data from: Multiple independent origins of intermediate species between Sorbus aucuparia and S. hybrida (Rosaceae) in the Baltic region

description: Populations intermediate between the diploid and sexual Sorbus aucuparia
 and the tetraploid and facultative apomictic Sorbus hybrida are scattered
 in coastal regions of southern Scandinavia. Our aims were to investigate
 whether these populations were of local and independent origins, whether
 they were morphologically and molecularly distinct from each other and
 whether they could give rise to constant offspring by apomixis. Six
 intermediate populations from the Baltic Sea basin were studied for
 variation at nuclear and plastid microsatellite loci, for morphological
 differentiation patterns, and for ploidy level by flow cytometry. Seeds
 were sown to check for constancy with the mother plants. Three populations
 from Gotland and possibly the small population from Uppland were in each
 case fixed for a unique combination of genetic markers, had restricted
 variation in leaf shape and were morphologically divergent from each
 other. Flow cytometry analysis showed that the four genetically
 monomorphic populations were consistently triploid. Cultivation showed
 that offspring from trees within two of the monomorphic populations had
 leaf shapes closely similar to the mother individuals. In contrast, a
 population from Gotland and a population from Åland were variable at
 molecular marker loci and were variable in leaf shape. The three
 monomorphic Gotland populations and possibly also the Uppland population
 propagate asexually by apomixis, and they have independent origins. The
 two variable populations are apparently composed of hybrids that have been
 formed repeatedly and independently between individuals of the two
 parental species growing at the same sites. One of the Gotland apomicts
 has already been described as Sorbus teodori. Sorbus faohraei Hedrén
 & J.Levin and Sorbus atrata Hedrén & J.Levin are described
 as new apomictic species from Gotland.

title: Data from: Behavioural tuning in a tropical amphibian along an altitudinal gradient

description: Males of the Coqui treefrog, Eleutherodactylus coqui, produce a distinct
 two-note ‘co-qui’ advertisement call from sunset to midnight throughout
 most of the year. Previous work established that both the spectrotemporal
 aspects of the call and the frequency of highest inner-ear sensitivity
 changes with altitude above sea level. These variations are such that the
 frequency of the emitted co-note closely matches the frequency to which
 the inner-ear is most sensitive. Given this parallel variation, we
 expected that the call-evoked behavioural response of male Coqui treefrogs
 would also show an altitude-dependence, and hypothesized that males would
 produce their most robust acoustical territorial response to advertisement
 calls that match calls from their own altitude. We tested this hypothesis
 in the field by studying the vocal response behaviour of Coquis to
 playbacks of synthetic, altitude-dependent conspecific calls, and indeed
 found that the most robust vocal responses were obtained using stimuli
 closely matching the calls from the same altitude.

title: Data from: Spatial genetic variation and habitat association of Rhinichthys cataractae, the longnose dace, in the Driftless Area of the upper Mississippi River basin

description: The Driftless Area of the upper Mississippi River drainage is a unique
 geographic region because of its complex geological history and the
 influence of recent, intensive human activities. The longnose dace,
 Rhinichthys cataractae, is a relatively common, small freshwater fish that
 is distributed in swift, cool streams within the region. The aim of this
 study was to determine the spatial genetic differentiation of the longnose
 dace and define the broad scale environmental variables that shape the
 distribution of the species in the southwestern portion of the Driftless
 Area. Genotypic data from seven microsatellite loci were analyzed for 276
 individuals from 15 localities representing major drainages within the
 region in northeast Iowa. Broad scale environmental variables including
 hydrologic, soil, and climatic factors were evaluated to construct an
 ecological niche model (ENM) to predict the suitability of habitat for the
 species within the region. Results of the genetic analyses revealed two
 distinct, but somewhat admixed genetic clusters of longnose dace in Iowa.
 The genetic differentiation between localities and between drainages was
 low to moderate with some evidence of isolation by distance. Most of the
 variation was observed by differences between individuals within local
 populations. The ENM generated largely reflected the known distribution of
 the species in Iowa with a decreasing probability of suitable habitat from
 northern to southern drainages. Geologic factors played a key role in the
 model. The distribution and population structure of the longnose dace in
 the northeast Iowa revealed that isolation by distance, historical
 processes and the underlying geology are primarily responsible for the
 observed spatial distribution of genetic variation.

title: Data from: Quantification of population sizes of large herbivores and their long-term functional role in ecosystems using dung fungal spores

description: The relationship between large herbivore numbers and landscape cover over
 time is poorly understood. There are two schools of thought: one views
 large herbivores as relatively passive elements upon the landscape and the
 other as ecosystem engineers driving vegetation succession. The latter
 relationship has been used as an argument to support reintroductions of
 large herbivores onto many landscapes in order to increase vegetation
 heterogeneity and biodiversity through local-scale disturbance regimes.
 Most of the research examining the relationship between large herbivores
 and their impact on landscapes has used extant studies. An alternative
 approach is to estimate the impact of variations in herbivore populations
 through time using fossil dung fungal spores and pollen in sedimentary
 sequences. However, to date, there has been little quantification of
 fossil dung fungal spore records and their relationship to herbivore
 numbers, leaving this method open to varied interpretations. In this
 study, we developed further the dung fungal spore method and determined
 the relationship between spore abundance in sediments (number cm−2 year−1)
 and herbivore biomass densities (kg ha−1). To establish this relationship,
 we used the following: (i) the abundance of Sporormiella spp., Sordaria
 spp. and Podospora spp. spores in modern sediments from ponds and (ii)
 weekly counts of contemporary wildlife over a period of 5 years from the
 rewilded site, Oostvaardersplassen, in the Netherlands. Results from this
 study demonstrate that there is a highly significant relationship between
 spore abundance and local biomass densities of herbivores that can be used
 in the calibration of fossil records. Mammal biomass density (comprising
 Konik horses, Heck cattle and red deer) predicts in a highly significant
 way the abundance of all dung fungal spores amalgamated together. This
 relationship is apparent at a very local scale (&lt;10 m), when the
 characteristics of the sampled ponds are taken into account (surface area
 of pond, length of shoreline). In addition, we identify that dung fungal
 spores are principally transported into ponds by surface run-off from the
 shores. These results indicate that this method provides a robust
 quantitative measure of herbivore population size over time.

title: Data from: Carotenoids, birdsong and oxidative status: administration of dietary lutein is associated with an increase in song rate and circulating antioxidants (albumin and cholesterol) and a decrease in oxidative damage

description: Despite the appealing hypothesis that carotenoid-based colouration signals
 oxidative status, evidence supporting the antioxidant function of these
 pigments is scarce. Recent studies have shown that lutein, the most common
 carotenoid used by birds, can enhance the expression of non-visual traits,
 such as birdsong. Nevertheless, the underlying physiological mechanisms
 remain unclear. In this study we hypothesized that male European starlings
 (Sturnus vulgaris) fed extra lutein increase their song rate as a
 consequence of an improved oxidative status. Although birdsong may be
 especially sensitive to the redox status, this has, to the best of our
 knowledge, never been tested. Together with the determination of
 circulating oxidative damage (ROMs, reactive oxygen metabolites), we
 quantified uric acid, albumin, total proteins, cholesterol, and
 testosterone, which are physiological parameters potentially sensitive to
 oxidation and/or related to both carotenoid functions and birdsong
 expression. We found that the birds fed extra lutein sang more frequently
 than control birds and showed an increase of albumin and cholesterol
 together with a decrease of oxidative damage. Moreover, we could show that
 song rate was associated with high levels of albumin and cholesterol and
 low levels of oxidative damage, independently from testosterone levels.
 Our study shows for the first time that song rate honestly signals the
 oxidative status of males and that dietary lutein is associated with the
 circulation of albumin and cholesterol in birds, providing a novel insight
 to the theoretical framework related to the honest signalling of
 carotenoid-based trait

title: Data from: In-situ recording of ionic currents in projection neurons and Kenyon cells in the olfactory pathway of the honeybee

description: The honeybee olfactory pathway comprises an intriguing pattern of
 convergence and divergence: ~60.000 olfactory sensory neurons (OSN) convey
 olfactory information on ~900 projection neurons (PN) in the antennal lobe
 (AL). To transmit this information reliably, PNs employ relatively high
 spiking frequencies with complex patterns. PNs project via a dual
 olfactory pathway to the mushroom bodies (MB). This pathway comprises the
 medial (m-ALT) and the lateral antennal lobe tract (l-ALT). PNs from both
 tracts transmit information from a wide range of similar odors, but with
 distinct differences in coding properties. In the MBs, PNs form synapses
 with many Kenyon cells (KC) that encode odors in a spatially and
 temporally sparse way. The transformation from complex information coding
 to sparse coding is a well-known phenomenon in insect olfactory coding.
 Intrinsic neuronal properties as well as GABAergic inhibition are thought
 to contribute to this change in odor representation. In the present study,
 we identified intrinsic neuronal properties promoting coding differences
 between PNs and KCs using in-situ patch-clamp recordings in the intact
 brain. We found very prominent K+ currents in KCs clearly differing from
 the PN currents. This suggests that odor coding differences between PNs
 and KCs may be caused by differences in their specific ion channel
 properties. Comparison of ionic currents of m- and l-ALT PNs did not
 reveal any differences at a qualitative level.

title: Data from: Life in the unthinking depths: energetic constraints on encephalization in marine fishes

description: Several hypotheses have been proposed to explain the limitation of brain
 size in vertebrates. Here we test three hypotheses of brain size evolution
 using marine teleost fishes: the direct metabolic constraints hypothesis,
 the expensive tissue hypothesis, and the temperature-dependent hypothesis.
 Our analyses indicate that there is a robust positive correlation between
 encephalization and basal metabolic rate that spans the full range of
 depths occupied by teleosts from the epipelagic (&lt; 200m),
 mesopelagic (200-1000m), and bathypelagic (&gt; 4000m). Our results
 disentangle the effects of temperature and metabolic rate on teleost brain
 size evolution, supporting the direct metabolic constraints hypothesis.
 Our results agree with previous findings that teleost brain size decreases
 with depth, however, we also recover a negative correlation between
 trophic level and encephalization within the mesopelagic zone, a result
 that runs counter to the expectations of the expensive tissue hypothesis.
 We hypothesize that mesopelagic fishes at lower trophic levels may be
 investing more in neural tissue related to the detection of small prey
 items in a low-light environment. We recommend that comparative
 encephalization studies control for basal metabolic rate in addition to
 controlling for body size and phylogeny.
