title: Data from: Behavioral hypervolumes of predator groups and predator-predator interactions shape prey survival rates and selection on prey behavior

description: Predator-prey interactions often vary on the basis of the traits of the
 individual predators and prey involved. Here we examine whether the
 multidimensional behavioral diversity of predator groups shapes prey
 mortality rates and selection on prey behavior. We ran individual sea
 stars (Pisaster ochraceus) through three behavioral assays to characterize
 individuals’ behavioral phenotype along three axes. We then created groups
 that varied in the volume of behavioral space that they occupied. We
 further manipulated the ability of predators to interact with one another
 physically via the addition of barriers. Prey snails (Chlorostome
 funebralis) were also run through an assay to evaluate their predator
 avoidance behavior before their use in mesocosm experiments. We then
 subjected pools of prey to predator groups and recorded the number of prey
 consumed and their behavioral phenotypes. We found that predator-predator
 interactions changed survival selection on prey traits: when predators
 were prevented from interacting, more fearful snails had higher survival
 rates, whereas prey fearfulness had no effect on survival when predators
 were free to interact. We also found that groups of predators that
 occupied a larger volume in behavioral trait space consumed 35% more prey
 snails than homogeneous predator groups. Finally, we found that behavioral
 hypervolumes were better predictors of prey survival rates than single
 behavioral traits or other multivariate statistics (i.e., principal
 component analysis). Taken together, predator-predator interactions and
 multidimensional behavioral diversity determine prey survival rates and
 selection on prey traits in this system.

title: Data from: Zoogeography of epigean freshwater Amphipoda (Crustacea) in Romania: fragmented distributions and wide altitudinal variability

description: Inland epigean freshwater amphipods of Romania are diverse and abundant
 for this region has a favourable geographical position between the Balkans
 and the Black Sea. Excluding Ponto-Caspian species originating in brackish
 waters and freshwater subterranean taxa, there are 11 formally recognized
 epigean freshwater species recorded from this country. They belong to 3
 genera, each representing a different family: Gammarus (Gammaridae, 8
 species or species complexes), Niphargus (Niphargidae, 2 epigean species)
 and Synurella (Crangonyctidae, one species). Their large-scale
 distribution patterns nevertheless remain obscure due to insufficient
 data, consequently limiting biogeographical interpretations. We provide
 extensive new data with high resolution distribution maps, thus improving
 the knowledge of the ranges of these taxa. Gammarus species display
 substantial altitudinal variability and patchy, fragmented distribution
 patterns. They occur abundantly, particularly in springs and streams, from
 lowlands to sub-mountainous and mountainous regions. In the light of
 recent molecular research, we hypothesize that the complex
 geomorphological dynamics of the Carpathian region during the Late
 Tertiary probably contributed to their allopatric distribution pattern.
 Contrasting with Gammarus, the genera Niphargus and Synurella exhibit low
 altitudinal variability, broad ecological valences and overlapping
 distributions, being widespread throughout the lowlands. The current
 distribution of N. hrabei and N. valachicus seems to be linked to the
 extent of the Paratethys during the Early Pliocene or Pleistocene. We
 further discuss the taxonomic validity of two synonymized and one
 apparently undescribed taxon, and provide an updated pictorial
 identification key that includes all taxa and forms discussed in our
 study. The mosaic distribution of epigean freshwater amphipod species in
 Romania shows that this region is particularly suitable for phylo- and
 biogeographical analyses of this group.

title: Data from: Plant functional composition affects soil processes in novel successional grasslands

description: 1. Secondary succession may lead to novel, exotic-dominated community
 states differing in structure and function from the original native
 counterparts. We hypothesized that grassland soil processes associated
 with C and N cycling decelerate with community turnover from short-lived
 forbs and grasses to long-lived native grasses, whereas invasion by exotic
 perennial grasses maintains fast cycling rates. 2. We measured litter C
 and N turnover during decomposition, soil respiration, and soil N dynamics
 in synthetic plant communities resembling four successional stages,
 established on abandoned farmland in the Inland Pampa, Argentina. We also
 compared litter chemistry and decay rates of dominant species from each
 community stage in a common garden, and assessed mass loss for a standard
 litter type incubated in all communities. 3. Litter decomposition and soil
 respiration decreased, while litter N retention increased from early,
 through mid to late community stages dominated by forbs, short-lived
 grasses and native perennial grasses, respectively. Soil process rates in
 exotic perennial grass communities were faster than in native grass
 communities, but similar to annual grass communities. Further, the
 standard litter decomposed more slowly in the native perennial than in the
 exotic perennial grass community. In the common garden, short-lived forbs
 and grasses decomposed faster than native or exotic perennial grasses,
 with species’ decay rates being negatively related to initial litter C:N
 ratio. 4. Our results show that changes in soil processes across old-field
 communities arise chiefly through differences in the quality of litter
 produced by dominant functional groups. A dominance shift from native to
 exotic perennial grasses prevented the deceleration of C and N cycling
 expected with plant successional turnover. Thus invasion by fast-growing
 exotic grasses may fundamentally alter ecosystem functioning in novel
 grasslands.

title: Data from: Influence of plant-pollinator interactions on the assembly of plant and hummingbird communities

description: Understanding how ecological processes structure species assemblages is a
 central issue in community ecology. While the influence of
 plant–pollinator interactions on each other's evolution is well
 recognized, their role in the assembly of interdependent communities of
 plants and pollinators is still unclear. Using data from seven communities
 of hummingbirds and plants that they pollinate from two tropical rain
 forest types (lowland and montane), we evaluated phylogenetic
 relationships and signal of functional traits, over space and time, to
 test predictions on the main processes (environmental filtering,
 facilitation or competition) that are driving these hummingbird–plant
 assemblages. Our findings suggest that the main processes driving these
 assemblages varied between hummingbirds and plants and between habitats,
 and even among communities at the same habitat. The non-conserved floral
 trait and the phylogenetic patterns (even or random) give support to the
 hypothesis of facilitation or competition as processes regulating the
 composition of plant assemblages. Moreover, the positive relationship
 between fitness and flowering synchrony suggests facilitation as the most
 important mechanism for montane plant communities. Distinctively, for
 lowland plant communities, the combination of non-conserved traits and
 clustered phylogenetic patterns may be a result of either adaptive
 radiation or biotic filtering driven by a particular pollinator species
 that plays a main role as plant community organizer. Lastly, evidence of
 trait conservatism, together with clustered or even phylogenetic patterns,
 suggests that facilitation or competition may drive the assembly of
 montane hummingbird communities, despite the predominance of random
 phylogenetic patterns. Synthesis. Overall, we present a pathway to
 identify central ecological processes that may drive the assembly of
 plant–pollinator communities. We show that different processes related
 with pollination that vary in space and time may contribute to the
 assembly of the interdependent tropical communities of plants and
 pollinators. These findings highlight the importance of considering
 ecological interactions when evaluating community assembly processes.

title: Data from: Parents face quantity-quality tradeoffs between reproduction and investment in offspring in Iceland

description: How to optimally allocate time, energy and investment in an effort to
 maximize one's reproductive success is a fundamental problem faced by
 all organisms. This effort is complicated when the production of each
 additional offspring dilutes the total resources available for parental
 investment. Although a quantity–quality trade-off between producing and
 investing in offspring has long been assumed in evolutionary biology,
 testing it directly in humans is difficult, partly owing to the long
 generation time of our species. Using data from an Icelandic genealogy
 (Íslendingabók) over two centuries, I address this issue and analyse the
 quantity–quality trade-off in humans. I demonstrate that the primary
 impact of parents on the fitness of their children is the result of
 resources and or investment, but not genes. This effect changes
 significantly across time, in response to environmental conditions.
 Overall, increasing reproduction has negative fitness consequences on
 offspring, such that each additional sibling reduces an individual's
 average lifespan and lifetime reproductive success. This analysis provides
 insights into the evolutionary conflict between producing and investing in
 children while also shedding light on some of the causes of the
 demographic transition.

title: Data from: Ecological specialization in fossil mammals explains Cope's rule

description: Cope’s rule is the trend toward increasing body size in a lineage over
 geological time. The rule has been explained either as passive diffusion
 away from a small initial body size or as an active trend upheld by the
 ecological and evolutionary advantages that large body size confers. An
 explicit and phylogenetically informed analysis of body size evolution in
 Cenozoic mammals shows that body size increases significantly in most
 inclusive clades. This increase occurs through temporal substitution of
 incumbent species by larger-sized close relatives within the clades. These
 late-appearing species have smaller spatial and temporal ranges and are
 rarer than the incumbents they replace, traits that are typical of
 ecological specialists. Cope’s rule, accordingly, appears to derive mainly
 from increasing ecological specialization and clade-level niche expansion
 rather than from active selection for larger size. However, overlain on a
 net trend toward average size increase, significant pulses in origination
 of large-sized species are concentrated in periods of global cooling.
 These pulses plausibly record direct selection for larger body size
 according to Bergmann’s rule, which thus appears to be independent of but
 concomitant with Cope’s.

title: Data from: Consistent size-independent harvest selection on fish body shape in two recreationally exploited marine species

description: Harvesting wild animals may exert size-independent selection pressures on
 a range of morphological, life history, and behavioral traits. Most work
 so far has focused on selection pressures on life history traits and body
 size as morphological trait. We studied here how recreational fishing
 selects for morphological traits related to body shape, which may
 correlate with underlying swimming behavior. Using landmark-based
 geometric morphometrics, we found consistent recreational fishing-induced
 selection pressures on body shape in two recreationally exploited marine
 fish species. We show that individuals with larger-sized mouths and more
 streamlined and elongated bodies were more vulnerable to passively
 operated hook-and-line fishing independent of the individual's body
 size or condition. While the greater vulnerability of individuals with
 larger mouth gapes can be explained by the direct physical interaction
 with hooks, selection against streamlined and elongated individuals could
 either involve a specific foraging mode or relate to underlying elevated
 swimming behavior. Harvesting using passive gear is common around the
 globe, and thus, size-independent selection on body shape is expected to
 be widespread potentially leaving behind individuals with smaller oral
 gapes and more compact bodies. This might have repercussions for food webs
 by altering foraging and predation.

title: Data from: Detecting slow introgression of invasive alleles in an extensively restocked game bird

description: Interbreeding of two species in the wild implies introgression of alleles
 from one species into the other only when admixed individuals survive and
 successfully backcross with the parental species. Consequently, estimating
 the proportion of first generation hybrids in a population may not inform
 about the evolutionary impact of hybridization. Samples obtained over a
 long time span may offer a more accurate view of the spreading of
 introgressed alleles in a species’ gene pool. Common quail (Coturnix
 coturnix) populations in Europe have been restocked extensively with farm
 quails of hybrid origin (crosses with Japanese quails, C. japonica). We
 genetically monitored a common quail population over 15 years to
 investigate whether genetic introgression is occurring and used
 simulations to investigate our power to detect it. Our results revealed
 that some introgression has occurred, but we did not observe a significant
 increase over time in the proportion of admixed individuals. However,
 simulations showed that the degree of admixture may be larger than
 anticipated due to the limited power of analyses over a short time span,
 and that observed data was compatible with a low rate of introgression,
 probably resulting from reduced fitness of admixed individuals.
 Simulations predicted this could result in extensive admixture in the near
 future.

title: Data from: Comparison of capture and storage methods for aqueous macrobial eDNA using an optimized extraction protocol: advantage of enclosed filter

description: Aqueous environmental DNA (eDNA) is an emerging efficient non-invasive
 tool for species inventory studies. To maximize performance of downstream
 quantitative PCR (qPCR) and next-generation sequencing (NGS) applications,
 quality and quantity of the starting material is crucial, calling for
 optimized capture, storage and extraction techniques of eDNA. Previous
 comparative studies for eDNA capture/storage have tested precipitation and
 ‘open’ filters. However, practical ‘enclosed’ filters which reduce
 unnecessary handling have not been included. Here, we fill this gap by
 comparing a filter capsule (Sterivex-GP polyethersulfone, pore size 0·22
 μm, hereafter called SX) with commonly used methods. Our experimental
 set-up, covering altogether 41 treatments combining capture by
 precipitation or filtration with different preservation techniques and
 storage times, sampled one single lake (and a fish-free control pond). We
 selected documented capture methods that have successfully targeted a wide
 range of fauna. The eDNA was extracted using an optimized protocol
 modified from the DNeasy® Blood & Tissue kit (Qiagen). We measured
 total eDNA concentrations and Cq-values (cycles used for DNA
 quantification by qPCR) to target specific mtDNA cytochrome b (cyt b)
 sequences in two local keystone fish species. SX yielded higher amounts of
 total eDNA along with lower Cq-values than polycarbonate track-etched
 filters (PCTE), glass fibre filters (GF) or ethanol precipitation (EP). SX
 also generated lower Cq-values than cellulose nitrate filters (CN) for one
 of the target species. DNA integrity of SX samples did not decrease
 significantly after 2 weeks of storage in contrast to GF and PCTE. Adding
 preservative before storage improved SX results. In conclusion, we
 recommend SX filters (originally designed for filtering micro-organisms)
 as an efficient capture method for sampling macrobial eDNA. Ethanol or
 Longmire's buffer preservation of SX immediately after filtration is
 recommended. Preserved SX capsules may be stored at room temperature for
 at least 2 weeks without significant degradation. Reduced handling and
 less exposure to outside stress compared with other filters may contribute
 to better eDNA results. SX capsules are easily transported and enable eDNA
 sampling in remote and harsh field conditions as samples can be
 filtered/preserved on site.

title: Data from: Climate and local abundance in freshwater fishes

description: Identifying factors regulating variation in numbers of individuals among
 populations across a species' distribution is a fundamental goal in
 ecology. A common prediction, often referred to as the abundant-centre
 hypothesis, suggests that abundance is highest near the centre of a
 species' range. However, because of the primary focus on the
 geographical position of a population, this framework provides little
 insight into the environmental factors regulating local abundance. While
 range-wide variation in population abundance associated with environmental
 conditions has been investigated in terrestrial species, the relationship
 between climate and local abundance in freshwater taxa across
 species' distributions is not well understood. We used GIS-based
 temperature and precipitation data to determine the relationships between
 climatic conditions and range-wide variation in local abundance for 19
 species of North American freshwater fishes. Climate predicted a portion
 of the variation in local abundance among populations for 18 species. In
 addition, the relationship between climatic conditions and local abundance
 varied among species, which is expected as lineages partition the
 environment across geographical space. The influence of local habitat
 quality on species persistence is well documented; however, our results
 also indicate the importance of climate in regulating population sizes
 across a species geographical range, even in aquatic taxa.

title: Data from: Conditional reduction of predation risk associated with a facultative symbiont in an insect

description: Symbionts are widespread among eukaryotes and their impacts on the ecology
 and evolution of their hosts are meaningful. Most insects harbour obligate
 and facultative symbiotic bacteria that can influence their phenotype. In
 the pea aphid Acyrthosiphon pisum, an astounding symbiotic-mediated
 phenotype has been recently observed: when infected with the symbiotic
 bacteria Rickettsiella viridis, young red aphid larvae become greener at
 adulthood and even darker green when co-infected with Rickettsiella
 viridis and Hamiltonella defensa. As body colour affects the
 susceptibility towards natural enemies in aphids, the influence of the
 colour change due to these facultative symbionts on the host survival in
 presence of predators was tested. Our results suggested that the
 Rickettsiella viridis infection may impact positively host survival by
 reducing predation risk. Due to results from uninfected aphids (i.e., more
 green ones attacked), the main assumption is that this symbiotic infection
 would deter the predatory ladybird feeding by reducing the profitability
 of their hosts rather than decreasing host detection through body colour
 change. Aphids co-infected with Rickettsiella viridis and Hamiltonella
 defensa were, however, more exposed to predation suggesting an ecological
 cost associated with multiple infections. The underlying mechanisms and
 ecological consequences of these symbiotic effects are discussed.
