title: Data from: Exogenous glucocorticoids amplify the costs of infection by reducing resistance and tolerance, but effects are mitigated by co-infection

description: Individual variation in parasite defenses, such as resistance and
 tolerance, can underlie heterogeneity in fitness and could influence
 disease transmission dynamics. Glucocorticoid hormone concentrations often
 change in response to fluctuating environmental conditions and mediate
 changes in immune function, resource allocation, and tissue repair. Thus,
 changes in glucocorticoid hormone concentrations might mediate individual
 variation in investment in resistance versus tolerance. In this study, we
 experimentally increased glucocorticoid concentrations in red-winged
 blackbirds (Agelaius phoeniceus) that were naturally infected with
 haemosporidian parasites and assessed changes in resistance and tolerance
 of infection. Glucocorticoid treatment increased burdens of Plasmodium,
 the parasite causing avian malaria, but only in the absence of
 co-infection with another Haemosporidian, Haemoproteus. Thus,
 glucocorticoids might reduce resistance to infection, but co-infection can
 mitigate the negative consequences of increased hormone concentrations.
 Glucocorticoid treatment also decreased tolerance of infection. We found
 no evidence that the inflammatory immune response or rate of red blood
 cell production underlie the effects of glucocorticoids on resistance and
 tolerance. Our findings suggest that exogenous glucocorticoids can
 increase the costs of haemosporidian infections by both increasing
 parasite numbers and reducing an individual’s ability to cope with
 infection. These effects could scale up to impact populations of both host
 and parasite.
description: Pilot
 Study_dataWe conducted a pilot
 study to assess the effects of varying doses of corticosterone implants on
 circulating hormone concentrations, and to identify when we would likely
 observe resulting changes in parasite burden. We tested the ability of
 subcutaneous hormone implants to elevate baseline corticosterone over
 three weeks, including sampling time points ~8 h, ~32 h, 7 d, 14 d, and 21
 d post-implantation. We piloted three levels of 60-day slow release
 corticosterone implants (0.1 mg, 0.5 mg, and 1.5 mg corticosterone from
 Innovative Research of America, Sarasota, FL, USA), and compared their
 effects to sham-implant and no-implant controls. The data file contains
 hormone concentrations and other physiological measures taken throughout

title: Data from: Substrate and spatial variables are major determinants of fungal community in karst caves in Southwest China

description: Aim: Previous studies primarily based on the culture method have revealed
 that caves host a high fungal diversity and that exogenous carbon sources
 influence fungal communities. Here, we assess the fungal diversity and
 distribution patterns in karst caves in Southwest China and reveal the
 major factors that shape the fungal communities. Location: Southwest
 China. Methods: Samples of air, rock, sediment, and water were collected
 from eight caves in Southwest China. Using high-throughput sequencing of
 the internal transcribed spacer 1 region of fungal rDNA, we examined the
 cave fungal communities in Southwest China and studied their correlations
 with potentially influential factors, such as substrate, cave, location
 and environmental variables. Results: Approximately 10,000 fungal
 operational taxonomic units (OTUs) spanning 15 phyla were obtained. The
 highest diversity genus was Penicillium, while Mortierella had the highest
 relative abundance. Compared with air and rock samples, sediment and water
 samples harboured higher diversity and distinct communities. Substrate and
 cave were revealed to be the key determinants of the fungal communities in
 caves. Sample location and sampling distance from the entrance had more
 significant impacts on rock and sediment communities than on air and water
 assemblages. The fungal assemblages in air and water samples from the cave
 and outside cave environments were similar, while those of rock and
 sediment samples were significantly different. Main conclusions: Our
 results indicate that sediment and water harboured higher fungal diversity
 than air and rock, and substrate and spatial variables are key
 determinants of fungal communities in caves.

title: Data from: Honey bees flexibly use two navigational memories when updating dance distance information

description: Honey bees can communicate navigational information which makes them
 unique amongst all prominent insect navigators. Returning foragers recruit
 nest mates to a food source by communicating flight distance and direction
 using a small scale walking pattern: the waggle dance. It is still unclear
 how bees transpose flight information to generate corresponding dance
 information. In single feeder shift experiments, we monitored for the
 first time how individual bees update dance duration after a shift of
 feeder distance. Interestingly, the majority of bees (86%) needed two or
 more foraging trips to update dance duration. This finding demonstrates
 that transposing flight navigation information to dance information is not
 a reflexive behavior. Furthermore, many bees showed intermediate dance
 durations during the update process, indicating that honey bees highly
 likely use two memories: (i) a recently acquired navigation experience and
 (ii) a previously stored flight experience. Double shift experiments, in
 which the feeder was moved forward-backward, created an experimental
 condition in which honey bee foragers did not update dance duration;
 suggesting the involvement of more complex memory processes. Our
 behavioral paradigm allows the dissociation of foraging and dance activity
 and opens a possibility to study the molecular and neural processes
 underlying the waggle dance behavior.

title: Data from: Female cuticular hydrocarbons can signal indirect fecundity benefits in an insect

description: Male choosiness of prospective female mating partners provides an
 increasingly recognised pathway through which males can increase their
 fitness. For example, males may increase their number of offspring by
 targeting more fecund females as mating partners. If fecundity is
 heritable, males that mate with more fecund females can also receive the
 indirect benefit of more fecund daughters. In species where female
 fecundity is not directly assessable, female ornaments may act as signals
 of fecundity. However, whether female ornaments reliably signal the
 indirect benefit of more fecund daughters is not well understood. We
 investigated this question using the field cricket, Teleogryllus
 oceanicus. Previous work had identified the cuticular hydrocarbon (CHC)
 profile as a female sexual display trait in T. oceanicus. To examine
 whether CHCs can provide a reliable signal of fecundity, we tested whether
 individual CHC compounds and the first principal axis of CHC variation
 (PC1) are genetically correlated with ovary mass, a reliable proxy for
 fecundity in this species. We found significant genetic correlations
 between ovary mass and three individual CHC compounds, as well as PC1.
 This result indicates that by targeting females as mating partners based
 on their CHC profile, males can sire more fecund daughters.

title: Data from: Swapping birth and death: symmetries and transformations in phylodynamic models

description: Stochastic birth--death models provide the foundation for studying and
 simulating evolutionary trees in phylodynamics. A curious feature of such
 models is that they exhibit fundamental symmetries when the birth and
 death rates are interchanged. In this paper, we first provide intuitive
 reasons for these known transformational symmetries. We then show that
 these transformational symmetries (encoded in algebraic identities) are
 preserved even when individuals at the present are sampled with some
 probability. However, these extended symmetries require the death rate
 parameter to sometimes take a negative value. In the last part of this
 paper, we describe the relevance of these transformations and their
 application to computational phylodynamics, particularly to maximum
 likelihood and Bayesian inference methods, as well as to model selection.

description: Risks associated with food security due to climate change and patterns of socio-economic development. Risks to food security include availability and access to food, including population at risk of hunger, food price increases and increases in disability adjusted life years attributable to childhood underweight. Risks are assessed for two contrasted socio-economic pathways (SSP1 and SSP3) excluding the effects of targeted mitigation and adaptation policies.

title: Data from: The yeast mitochondrial pyruvate carrier is a hetero-dimer in its functional state

description: The mitochondrial pyruvate carrier (MPC) is critical for cellular
 homeostasis, as it is required in central metabolism for transporting
 pyruvate from the cytosol into the mitochondrial matrix. MPC has been
 implicated in many diseases and is being investigated as a drug target. A
 few years ago, small membrane proteins, called MPC1 and MPC2 in mammals
 and Mpc1, Mpc2 and Mpc3 in yeast, were proposed to form large protein
 complexes responsible for this function. However, the MPC complexes have
 never been isolated and their composition, oligomeric state and functional
 properties have not been defined. Here, we identify the functional unit of
 MPC from Saccharomyces cerevisiae. In contrast to earlier hypotheses, we
 demonstrate that MPC is a hetero‐dimer, not a multimeric complex. When not
 engaged in hetero‐dimers, the yeast Mpc proteins can also form homo‐dimers
 that are, however, inactive. We show that the earlier described substrate
 transport properties and inhibitor profiles are embodied by the
 hetero‐dimer. This work provides a foundation for elucidating the
 structure of the functional complex and the mechanism of substrate
 transport and inhibition.

title: Data from: Altered leaf litter quality exacerbates the negative impact of climate change on decomposition

description: 1.Leaf litter decomposition is a key component of global biogeochemical
 cycles that influences soil carbon storage, nutrient availability and
 plant productivity. Ongoing climate change will lead to warmer and drier
 conditions in many dryland regions, potentially affecting litter
 decomposition and nutrient dynamics. Climate change effects can be direct
 and/or indirect, e.g. through changes in litter quality, yet their
 relative importance on litter decomposition remains unclear. 2. We
 conducted a manipulative study in a semiarid shrubland to assess the
 effects of leaf litter quality, forecasted climate change, i.e. +2.5°C
 warming (W), 30% rainfall reduction (RR), as well as their interaction
 (W+RR) to elucidate their relative effects on litter decomposition. 3.
 Climatic effects alone reduced decomposition of a homogeneous control leaf
 litter collected from Helianthemum squamatum shrubs growing in
 unmanipulated plots by 23.4%, 18.1%, and 29.8% in the W, RR and W+RR
 treatments, respectively. Leaf litter quality was lower in shrubs that had
 been growing in warmed plots (W and W+RR), as they had lower nutrient
 concentrations (P, Fe) and higher C:N and C:P ratios than leaf litter
 produced under ambient (control) conditions. Lignin concentration was
 significantly lower in litter from W+RR plots, yet when both climate and
 litter quality were considered simultaneously, decomposition rates were
 32.0%, 26.3% and 39.9% lower in W, RR and W+RR plots compared to controls.
 In addition, we found greater microbial N immobilization in leaf litter
 incubated within warmed (W and W+RR) than within non‐warmed plots (Control
 and RR). Structural equation modelling showed that higher litter moisture
 and microbial biomass contents stimulated decomposition. Simulated climate
 change (W, RR and W+RR) reduced decomposition indirectly by negatively
 affecting litter moisture contents and litter microbial biomass. Microbial
 nitrogen immobilization was stimulated by the lower quality (i.e. high C:N
 ratios) of the leaf litter collected in shrubs from warmed plots (W and
 W+RR). 4. Synthesis Our findings indicate that forecasted climate change
 conditions slow down C and N cycling in a dryland ecosystem, an effect
 that is further exacerbated by climate change‐induced reductions in litter
 quality and related reductions in bacterial and fungal biomass in litter.

title: Data from: Do the high energy lifestyles of shorebirds result in high maximal metabolic rates? - Basal and maximal metabolic rates in least and pectoral sandpipers during migration

description: Shorebirds have high resting and field metabolic rates relative to many
 other bird groups, and this is posited to be related to their high-energy
 lifestyle. Maximum metabolic outputs for cold or exercise are also often
 high for bird groups with energetically demanding lifestyles. Moreover,
 shorebirds demonstrate flexible basal and maximal metabolic rates, which
 vary with changing energy demands throughout the annual cycle.
 Consequently, shorebirds might be expected to have high maximum metabolic
 rates, especially during migration periods. We captured least (Calidris
 minutilla) and pectoral (C. melanotos) sandpipers during spring and fall
 migration in southeastern South Dakota and measured maximal exercise
 metabolic rate (MMR; least sandpipers only), summit metabolic rate (Msum,
 maximal cold-induced metabolic rate) and basal metabolic rate (BMR,
 minimum maintenance metabolic rate) with open-circuit respirometry. BMR
 for both least and pectoral sandpipers exceeded allometric predictions by
 3-14%, similar to other shorebirds, but Msum and MMR for both species were
 either similar to or lower than allometric predictions, suggesting that
 the elevated BMR in shorebirds does not extend to maximal metabolic
 capacities. Old World shorebirds show the highest BMR during the annual
 cycle on the Arctic breeding grounds. Similarly, least sandpiper BMR
 during migration was lower than on the Arctic breeding grounds, but this
 was not the case for pectoral sandpipers, so our data only partially
 support the idea of similar seasonal patterns of BMR variation in New
 World and Old World shorebirds. We found no correlations of BMR with
 either Msum or MMR for either raw or mass-independent data, suggesting
 that basal and maximum aerobic metabolic rates are modulated independently
 in these species.

title: Data from: Kalana Lagerstatte crinoids: early Silurian (Llandovery) of central Estonia

description: The Kalana Lagerstätte of early Aeronian (Llandovery, Silurian) age in
 central Estonia preserves a diverse shallow marine biota dominated by
 non-calcified algae. This soft-tissue flora and decalcified and calcified
 crinoids are preserved in situ, in a lens of microlaminated, dolomitized
 micrite interbedded in a sequence of dolomitized packstones and
 wackestones. Although the Lagerstätte is dominated by non-calcified algae,
 crinoids (together with brachiopods and gastropods) are among the most
 common organisms that were originally comprised of a carbonate skeleton.
 Two new crinoids are described from this unit, Kalanacrinus mastikae
 (large camerate) and Tartucrinus kalanaensis (small disparid).
 Interestingly, these two crinoids display contrasting preservation with
 the more common large camerate preserved primarily as a decalcified
 organic residue, whereas the smaller disparid is preserved primarily in
 calcite. Preservation was assessed using elemental mapping of C, Ca, S,
 and Si. Columns have the highest portion of Ca, once living soft tissue is
 indicated by C, S was dispersed as pyrite or associated with organics, and
 Si is probably associated with clay minerals in the matrix. This new fauna
 increases our understanding of the crinoid radiation on Baltica following
 Late Ordovician extinctions.

title: Data from: It’s a trap! invasive common mynas learn socially about control-related cues

description: Social learning of novel threats coupled with adaptive generalization from
 learned to novel cues together provide the cognitive mechanisms by which
 adaptive avoidance of threats can spread rapidly both within and across
 generations. Whereas attention to effects of fishing and hunting on prey
 is increasing, nothing is known about how human predation can alter the
 behavior of invasive animals. Here, we examined whether common (Indian)
 mynas, Acridotheres tristis, one of the most widespread invasive birds in
 Australia, and invasive to many other parts of the world, are learning to
 respond to anthropogenic predation. We analyzed behavior at an
 experimental food patch provisioned by two distinctly clothed persons both
 before and after mynas had observed one of the two persons seemingly
 capture conspecifics inside a trap placed at the food patch. After the
 demonstration, mynas landed in smaller numbers at the food patch and took
 longer to land. Further, mynas alarm called more when provisioned by the
 person who had been involved in trapping. Future work will determine
 whether narrow generalization gradients are a consistent feature of
 synanthropic species or whether they broaden as a function of human
 predation threat level as is predicted by the Predator Recognition
 Continuum Hypothesis. Practical implications for control are discussed.

title: Data from: Genetic diversity and genetic structure of Decalobanthus boisianus in Hainan Island, China

description: Decalobanthus boisianus is a native plant of Hainan Island, China, which
 has caused considerable damage to tropical forest ecosystems in recent
 decades. Understanding the genetic diversity and structure of this species
 can facilitate uncovering the molecular mechanism of its invasive ability.
 Here, we collected 77 individuals of D. boisianus spanning 8 distribution
 areas with a gradient of human disturbance intensity (i.e. low, moderate
 and high disturbance intensity groups), to assess patterns of genetic
 diversity and structure using inter-simple sequence repeat (ISSR) markers.
 We found that a total of 220 loci were scored with 13 primers using ISSR
 methods, and that 198 loci were polymorphic. The genetic diversity of D.
 boisianus among these eight forests decreased with increasing human
 disturbance intensity. Over 70% of the total genetic variation was present
 within populations, while less than 30% of variation was found among
 populations. There was a high gene flow (1.27) among them due to a lack of
 effective geographic barriers. The mean Nei's genetic distance of D.
 boisianus populations was found to be relatively small (i.e., 0.07), and
 the average genetic similarity of the eight populations was high (i.e.,
 0.93). Our findings indicate that the genetic diversity of D. boisianus
 corelated to human disturbance density, and that D. boisianus populations
 in Hainan Island have frequent gene exchange. We suggest that reduce
 deforestation to decrease human disturbance may be a good way to prevent
 the invasion of D. boisianus.

title: Data from: Adaptation to seasonal drought in two closely related species of Neotropical Costus (Costaceae)

description: Seasonal drought has been shown to greatly influence the distributions and
 species composition of plants in tropical rainforests. By conducting a
 series of field, greenhouse, and growth chamber experiments, we examined
 how Costus villosissimus, a forest edge species, has adapted to drought
 and differentiated from C. allenii, its closely related species in the
 understory. We hypothesize that delayed seed germination and high drought
 tolerance may lead to habitat differentiation and thus reproductive
 isolation between closely related plant species in the tropics.
