title: The effects of host plant species and larval density on immune function in the polyphagous moth Spodoptera littoralis

description: Immune functions are costly and immune investment is usually dependent on
 the individual’s condition and resource availability. For phytophagous
 insects, host plant quality has large effects on performance, e.g. growth
 and survival, and may also affect their immune function. Polyphagous
 insects often experience a large variation in quality among different host
 plant species, and their immune investment may thus vary depending on
 which host plant species they develop on. Larvae of the polyphagous
 moth Spodoptera littoralishave previously been found to exhibit
 density-dependent prophylaxis as they invest more in certain immune
 responses in high population densities. In addition, the immune response
 of S. littoralis has been shown to depend on nutrient
 quality in experiments with artificial diet. Here, I studied the effects
 of natural host plant diet and larval density on a number of immune
 responses to understand if host plant species affects immune investment in
 generalist insects, and if the density-dependent prophylaxis could be
 mediated by host plant species. While host plant species in general did
 not mediate the density-dependent immune expression, particular host plant
 species was found to increase larval investment in certain functions of
 the immune system. Interestingly, these results indicate that different
 host plants may provide a polyphagous species with protection against
 different kinds of antagonisms. This insight may contribute to our
 understanding of the relationship between preference and performance in
 generalists, as well as having applied consequences for sustainable pest
 management.
description: Immune assay data (degree of cuticular melanisation, area of
 encapsulated nylon piece, darkness of encaupsulation, log lysozyme
 activity in hemolymph, square root transformed phenoloxidase content
 of hemolymph as well as square root transformed protein content of
 hemolymph) for larvae that were raised in either high or low density (4 or
 1 larvae) and fed either cotton, cabbage or maize plants. Missing values
 exist because not all immune assays were possible to perform with every
 larvae e.g. due to that the nylon piece inserted for encapsulation assay
 fell out or that the extracted hemolymph was not enough for all
 assays.

title: Data from: Substantial intraspecific variation in energy budgets: biology or artefact?

description: Data on the growth and reproduction of Trinidadian guppies (Poecilia
 reticulata) from sixteen different populations, reared under experimental
 conditions of either high or low food availability. These data
 were used to fit dynamic energy budgets models for each of the
 populations. For twelve populations, there are three sets of observations
 per individual, recorded at each successive parturition event. For four of
 the populations, data were recorded at each parturition event over the
 full lifespan of each individual. 
description: These are data on the growth and reproduction of individually
 housed Trinidadian guppies, reared under experimental conditions of either
 low or high food.  Data are collated from three sets of experiments that
 followed the same general protocol, although the experimental food
 treatments differed between experiments. Please refer to the manuscript

title: Phenotypic, fitness and environmental data in support of the publication: selection favors adaptive plasticity in a long-term reciprocal transplant experiment

description: Spatial and temporal environmental variation can favor the evolution of
 adaptive phenotypic plasticity, such that genotypes alter their phenotypes
 in response to local conditions to maintain fitness across heterogeneous
 landscapes. When individuals show greater fitness in one habitat than
 another, asymmetric migration can restrict adaptation in the lower quality
 environment. In these cases, selection is predicted to favor traits that
 enhance fitness in the higher-quality habitat at the expense of fitness in
 the marginal habitat. Here, we test whether plasticity is
 adaptive in a system regulated by demographic source-sink
 dynamics. Vaccinium elliottii (Ericaceae) occurs in dry upland
 and flood-prone bottomland forests throughout the southeastern United
 States, and shows patterns consistent with source-sink dynamics. We
 conducted a multi-year field experiment to evaluate whether plasticity in
 foliar morphology increases survival and lifespan. Both across and within
 habitats, selection favored plasticity in specific leaf area, stomatal
 density, and leaf size. Stabilizing selection acted on plasticity in
 stomatal density within habitats, suggesting that extreme levels of
 plasticity are disadvantageous. Thus, even in systems driven by
 source-sink dynamics, temporal and spatial variation in conditions across
 the landscape and within habitat types can favor the evolution of
 plasticity.

title: Interplay of population size and environmental fluctuations: a new explanation for fitness cost rarity in asexuals

description: Theoretical models of ecological specialization commonly assume that
 adaptation to one environment leads to fitness reductions (costs) in
 others. However, experiments often fail to detect such costs. We addressed
 this conundrum using experimental evolution with Escherichia coli in
 several constant and fluctuating environments at multiple population
 sizes. We found that in fluctuating environments, smaller populations paid
 significant costs, but larger ones avoided them altogether. Contrastingly,
 in constant environments, larger populations paid more costs than the
 smaller ones. Overall, large population sizes and fluctuating environments
 led to cost avoidance only when present together. Mutational frequency
 distributions obtained from whole-genome whole-population sequencing
 revealed that the primary mechanism of cost avoidance was the enrichment
 of multiple beneficial mutations within the same lineage. Since the
 conditions revealed by our study for avoiding costs are widespread, it
 provides a novel explanation of the conundrum why the costs expected in
 theory are rarely detected in experiments.

title: Screening of anti-Acinetobacter baumannii phytochemicals, based on the potential inhibitory effect on OmpA and OmpW functions

description: Considering the adverse effect of antimicrobial resistance (AMR) crisis on
 human life, there is an immediate need for finding new alternative drugs
 for treatment of emerging infectious diseases. Therapeutic options,
 including last-line or combined antibiotic therapies for Acinetobacter
 baumannii, as a multi-drug resistant (MDR) human pathogen responsible for
 severe nosocomial and several other infections, are apparently
 ineffective. The outer membrane protein A (OmpA) and outer membrane
 protein W (OmpW) are two porins known for their different cellular
 functions. Identification of natural compounds with potentials to block
 these putative porins can possibly attenuate the growth of the bacteria
 and control the relating diseases. The current work aimed to screen a
 library of 384 phytochemicals according to their potentials to be used as
 a drug, and potentials to inhibit the function of OmpA and OmpW in A.
 baumannii. Although the anti-virulence activities of these biomolecules
 are reported previously, no evaluation of their effect on functional
 aspects of OmpA and OmpW in A. baumannii has been performed so far. In
 this study, the phytocompounds were initially screened based on their
 physicochemical, absorption, distribution, metabolism, excretion, and
 toxicity (ADMET) drug-like properties. Afterwards, the selected ligands
 were subjected to standard docking calculations against predicted
 three-dimensional structure of OmpA and OmpW in A. baumannii. We
 identified three phytochemicals (isosakuranetin, aloe-emodin and
 pinocembrin) bearing appreciable binding affinity towards the selected
 binding pocket of OmpA and OmpW. Molecular dynamics (MD) simulation
 analysis confirmed the stability of the complexes. Amongst them,
 isosakuranetin was suggested as the best phytocompounds for further in
 vitro and in vivo study.

title: Data and code from: Protection from fishing improves body growth of an exploited species

description: Hunting and fishing are often size-selective which favours slow body
 growth. In addition, fast growth rate has been shown to be positively
 correlated with behavioural traits that increase encounter rates and
 catchability in passive fishing gears such as baited traps. This
 harvest-induced selection should be effectively eliminated in no-take
 marine-protected areas (MPAs) unless strong density dependence results in
 reduced growth rates. We compared the body growth of European lobster
 (Homarus gammarus) between three MPAs and three fished areas. After 14
 years of protection from intensive, size-selective lobster fisheries, the
 densities in MPAs have increased considerably, and we demonstrate that
 females moult more frequently and grow more during each moult in the MPAs.
 A similar, but weaker pattern was evident for males. This study suggests
 that MPAs can shield a wild population from slow-growth selection, which
 can explain the rapid recovery of size structure following implementation.
 If slow-growth selection is a widespread phenomenon in fisheries, the
 effectiveness of MPAs as a management tool can be higher than currently
 anticipated.

title: Pollinator visitation, pollen deposition, and seed set for O. fruticosa

description: Heterospecific pollen transfer, the transfer of pollen between species, is
 common among co-flowering plants, yet the amount of pollen received is
 extremely variable among species. Intraspecific variation in
 heterospecific pollen receipt can be even greater, but we lack an
 understanding of its causes and fitness consequences in wild populations.
 We examined potential drivers of variation in heterospecific pollen
 receipt in Oenothera fruticosa. We evaluated the relationship between
 heterospecific and conspecific pollen receipt and considered how
 visitation by different pollinator groups, local floral neighborhood
 composition, and flowering phenology affect the total amount and
 proportion of heterospecific pollen received. Finally, we tested whether
 variation in heterospecific pollen receipt translated into lower seed
 production. Heterospecific pollen is ubiquitous on O. fruticosa stigmas,
 but the amount received is highly variable and unrelated to conspecific
 pollen receipt. Heterospecific pollen receipt depends on pollinator type,
 the proportion of nearby conspecific flowers, and flowering date.
 Significant interactions reveal that the effects of pollinator type and
 neighborhood are not independent, further contributing to variation in
 heterospecific pollen. Naturally occurring levels of heterospecific pollen
 were sufficient to negatively impact seed set, but large amounts of
 conspecific pollen counteracted this detrimental effect. Although
 selection could act on floral traits that attract quality pollinators and
 promote synchronous flowering in O. fruticosa, the risk of heterospecific
 pollen is equally dependent on local floral context. This work highlights
 how extrinsic and intrinsic factors contribute to intraspecific variation
 in heterospecific pollen receipt in wild plants, with significant fitness
 consequences.

title: Prey selection of polar bears in Foxe Basin, Nunavut, Canada: evidence of dietary flexibility in a specialized predator

description: Ecological flexibility of a species reflects its ability to cope with
 environmental change. Although polar bears (Ursus maritimus) are
 experiencing changes in foraging opportunities due to sea ice loss,
 regional prey availability and environmental conditions will influence the
 rate and severity of these effects. We examined changes in polar bear diet
 and the influence of sea ice characteristics in Foxe Basin over an 18-year
 period. We combined previous fatty acid data from bears harvested from
 1999-2003 (n = 82) with additional data from 2010-2018 (n = 397). Polar
 bear diets were diverse, however ringed seal (Pusa hispida) was the
 primary prey throughout the sample period. Prey contribution varied
 temporally and spatially, and by intrinsic factors, while the frequency of
 prey in diets varied over time suggesting that diet estimates reflect the
 variability in available prey. Bowhead whale (Balaena mysticetus),
 although still a minor dietary component, has more than doubled in
 frequency of occurrence in diets in recent years in association with
 increased scavenging opportunities. Higher dietary levels of beluga whale
 (Delphinapterus leucas) and harbour seal (Phoca vitulina) were
 linked to later breakup date suggesting heavier ice conditions may promote
 access to both prey species. The flexible foraging strategies of bears in
 Foxe Basin may help mitigate their vulnerability to changes in prey
 distribution and habitat conditions. Our results provide insights into the
 importance of alternative and supplemental food sources for polar bears
 during phenological changes in ice conditions that will likely have
 consequences to Arctic community structure as warming continues.
description: Data includes a set of 30 fatty acids (FAs) of individual polar
 bears and mean prey used to estimate predator diet via quantitative fatty
 acid signature analysis (QFASA). FAs are identified using the nomenclature
 A:Bn-X, where A is the carbon chain length, B is the number of double
 bonds, and X is the position of the first double bond in relation to the
 terminal methyl group. Typically, over 70 FAs are identified in each
 adipose tissue sample (of individual predator and prey) and expressed as
 the mass percentage of total FA.

title: Local male breeding density affects extra‐pair paternity in a south temperate population of grass wrens Cistothorus platensis

description: Demographic factors can affect the frequency of extra-pair paternity (EPP)
 in birds, as the distribution and availability of potential mates in both
 space and time influence the rate of encounters between females and males.
 Over three breeding seasons, we intensively studied the breeding system of
 a south temperate population of grass wrens Cistothorus platensis by
 genotyping 73 broods (319 nestlings) and estimating EPP rates for those
 broods. Using five different radii (80, 160, 240, 320, and 400 m) around
 each nest with assigned paternity, we examined the effects of local
 breeding synchrony, male breeding density, and adult sex ratio (ASR) on
 the EPP rate. The majority of extra-pair offspring (~80%) were sired by
 neighboring males. Neither local breeding synchrony nor ASR consistently
 explained the EPP rate variation as their effects were only statistically
 significant within 320 m and 400 m. However, the EPP rate increased as the
 local male breeding density increased within every radius category,
 strongly suggesting that neighboring male abundance might play an
 important role in the extra-pair mating behavior in this species. Our
 study also highlights the relevance of using a local scale approach when
 studying mating behavior.

title: Data for: Network of autoscopic hallucinations elicited by intracerebral stimulations of periventricular nodular heterotopia: an SEEG study

description: Periventricular nodular heterotopias (PVNH) are areas of neurons
 abnormally located in the white matter that might be involved in
  physiological cortical functions. Autoscopic hallucinations are
 changes in self-consciousness determined by a mismatch in integration of
 multiple sensory inputs. Our goal is to highlight the brain network
 involved in generation of autoscopic hallucination elicited by electrical
 stimulation of a PVNH in a drug resistant epilepsy patient.  Our
 patient was explored using stereo-electroencephalography with electrodes
 covering the right posterior temporal PVNH and the adjacent cortex. Direct
 electrical high frequency stimulation of the PVNH elicited autoscopic
 hallucinations mainly involving the face and upper trunk. We then used
 multiple modalities to determine brain connectivity: single pulse
 electrical stimulation of the PVNH and stimulation-evoked potentials were
 used to highlight resting state effective connectivity. High-frequency
 stimulation using alternating polarity pulses enabled us to identify the
 network involved, time-locked to the clinical effect and to map
 symptom-related effective connectivity. Functional connectivity using a
 non-linear regression method was used to determine dependencies between
 different cortical regions following the stimulation. Finally, structural
 connectivity was highlighted using deterministic fiber tracking.
 Multi-modal connectivity analysis identified a network involving the PVNH,
 occipital and temporal neocortex, fusiform gyrus and parietal cortex.

title: Phylogenomics of bonytongue fishes (Osteoglossomorpha) shed light on the craniofacial evolution and biogeography of the weakly electric clade (Mormyridae)

description: Bonytongues (Osteoglossomorpha) constitute an ancient clade of teleost
 fishes distributed in freshwater habitats throughout the world. The group
 includes well-known species such as arowanas, featherbacks, pirarucus, and
 the weakly electric fishes in the family Mormyridae. Their disjunct
 distribution, extreme morphologies, and electrosensory capabilities
 (Notopteridae and Mormyroidea) have attracted interest by many, yet a
 comprehensive phylogenetic framework for comparative analysis is missing.
 We provide a phylogenomic analysis of 179 species (out of 260), 28 out of
 29 genera, and all six families of extant bonytongues and find that the
 interfamilial relationships support previous molecular phylogenies.
 However, we find pervasive misalignment between the phylogeny and mormyrid
 taxonomy. Based on a recent reassessment of the fossil record of this
 group, we inferred dates of divergence among trans-continental clades and
 the major groups. The estimated ages of divergence for the major clades
 (e.g., Osteoglossomorpha, Osteoglossiformes, Mormyroidea) are older than
 previous reports, but most of the divergences of clades on separate
 continents are too young to be explained by biogeographic vicariance
 hypotheses. Ancestral state estimations of craniofacial phenotypes reveal
 pervasive convergence which may have contributed to taxonomic confusion.
 Biogeographic analysis of the Pan-African distribution of mormyrids
 indicates that their high species diversity in the Congo Basin is a
 consequence of range reductions of widespread ancestors. Finally, our
 results show that the highest diversity of craniofacial morphologies among
 mormyrids originated in the Congo Basin, suggesting niche partitioning of
 morphological and electrosensory adaptations of this uniquely diverse
 clade.

title: Xylem hydraulics and non-structural carbohydrate contents in 15 temperate tree species

description: In humid temperate forests, the occurrence of frequent freeze-thaw cycles
 (FTC) is a main factor limiting tree growth, as xylem embolism induced by
 FTC poses a serious threat to the hydraulic integrity of trees. A high
 resilience to hydraulic dysfunction involves the enhancement of embolism
 resistance and/or extra non-structural carbohydrate (NSC) inputs for
 restoration of an impaired hydraulic system. However, potentially negative
 implications of such NSC allocation on tree growth have not yet been
 explored. At a temperate forest site of northeast China, we studied xylem
 hydraulics and NSC contents in relation to winter embolism resilience in
 15 sympatric broadleaf tree species belonging to three genera with
 relatively high species richness, 6 Acer species,
 5 Betula species and 4 Populus species. Acer
 and Betula species had higher soluble sugar contents in the dormant season
 and indeed had higher hydraulic resilience to FTC induced embolism but
 slower stem growth. Populus species had higher NSC contents during the
 growing season and their faster stem growth was also consistent with
 higher hydraulic efficiency (Ks) and leaf photosynthetic rate. The
 positive correlation between tree trunk radial growth rate and hydraulic
 conductivity suggests that xylem water transport efficiency can be a
 fundamental basis for tree productivity due to a significant
 hydraulic-photosynthetic coordination. The negative correlation between
 soluble sugar concentration in the dormant season and stem growth rate
 indicates that metabolic carbon costs for enhancing hydraulic resilience
 may compromise tree growth during the growing season. Comparisons among
 Acer, Betula and Populus and the correlation analyses based on
 phylogenetic independent contrasts strongly support the existence of a
 trade-off between hydraulic resilience against FTC induced embolism and
 growth rate among sympatric tree species under humid temperate climate
 conditions. This trade-off has likely contributed to the sorting of
 temperate tree species and genera to different niches along environmental
 gradients with respect to freezing stress and interspecific competition.
