title: Processes underlying complex patterns of song trait evolution in a Setophaga hybrid zone

description: During secondary contact between two species when hybrids are less fit
 than parents, mating signals are expected to diverge while aggressive
 signals are expected to converge. If a single signal trait is used in both
 mating and aggression, then the dynamics between these two forces could
 influence the evolutionary trajectory of that trait. We studied such a
 situation in an avian hybrid zone between two Setophaga species, where
 birdsong is used in both mate attraction and territory defense. We
 hypothesized that song modules of the two species will show separate and
 distinct geographic patterns due to the influence of selective pressures
 for effective territorial aggression and for effective mate attraction. We
 conducted geographic cline analyses and playback experiments across this
 hybrid zone. We found an unexpected geographical pattern of asymmetric
 introgression of song rhythm, which may be explained by results of the
 playback experiments that suggest that differences in song rhythm serve a
 greater role in mate attraction than in territory defense. In contrast,
 differences in syllable morphology show little evidence of importance in
 mate attraction or territorial defense. Song features converge in the
 hybrid zone, yet patterns of trait change suggest that the song production
 modules may vary in their modes of development and inheritance. Syringeal
 motor gesturing, which gives rise to syllable morphology, shows a
 non-clinal mosaic pattern, suggesting that this trait may be predominantly
 learned. In contrast, respiratory patterning, which forms song rhythm,
 shows a clinal geographic transition, suggesting that this trait could be
 more innate. The results indicate that opposing forces act independently
 on song via distinct modules of the song production mechanism, driving
 complex patterns of song trait evolution.

title: Morphologic and metabolic data of Philaenus spumarius froghoppers

description: The xylem sap of vascular plants is an unlikely source of nutrition, being
 both nutrient poor and held under tensions (negative pressures) that can
 exceed 1 MPa. But some insects feed on xylem sap exclusively, extracting
 copious quantities using a muscular cibarial pump. However, neither the
 strength of the insect’s suction, nor the direct energetic cost of xylem
 ingestion, have ever been quantified. Philaenus spumarius froghoppers were
 used to address these gaps in our knowledge. Micro-CT scans of its
 cibarium and measurements of cibarial muscle sarcomere length revealed
 that P. spumarius can generate a maximum tension of 1.3 ± 0.2 MPa within
 its cibarium. The energetic cost of xylem extraction was quantified using
 respirometry to measure the metabolic rate (MR) of P. spumarius while they
 fed on hydroponically-grown legumes, while xylem sap excretion rate and
 cibarial pumping frequency were simultaneously recorded. Increasing the
 plants’ xylem tensions up to 1.1 MPa by exposing their roots to
 polyethylene glycol did not reduce the insects’ rate of xylem excretion,
 but significantly increased both MR and pumping frequency. We conclude
 that P. spumarius can gain energy feeding on xylem sap containing
 previously reported energy densities and at xylem tensions up to their
 maximum suction capacity.

title: Data from: Species boundaries in the messy middle – testing the hypothesis of micro-endemism in a recently diverged lineage of coastal fog desert lichen fungi

description: Species delimitation among closely related species is challenging because
 traditional phenotype-based approaches, e.g., morphology, ecological, or
 chemical characteristics, often produce conflicting results. With the
 advent of high-throughput sequencing, it has become increasingly
 cost-effective to acquire genome-scale data which can resolve previously
 ambiguous species boundaries. As the availability of genome-scale data has
 increased, numerous species delimitation analyses, such as BPP and
 SNAPP+Bayes factor delimitation (BFD*), have been developed to delimit
 species boundaries. However, even empirical molecular species delimitation
 approaches can be biased by confounding evolutionary factors, e.g.,
 hybridization/introgression and incomplete lineage sorting, and
 computational limitations. Here we investigate species boundaries
 and the potential for micro-endemism in a lineage of lichen-forming
 fungi, Niebla Rundel & Bowler in the family
 Ramalinaceae. The species delimitation models tend to support more
 specious groupings, but were unable to infer robust, consistent species
 delimitations. The results of our study highlight the problem of
 delimiting species, particularly in groups such
 as Niebla, with complex, recent phylogeographic
 histories.

title: Bending strength, compressive strength, and impact strength of POM after different ageing time at 100 ºC

description: Thermal-oxidative ageing of polyoxymethylene (POM) copolymer in oven at
 100 °C for 1, 2, 3, 5, 7, 10, 14 and 21 days and the influence of early
 thermal-oxidative on POM structure and properties were studied by means of
 wide-angle X-ray diffraction (WAXD), Fourier transform infrared
 spectroscopy (FTIR), differential scanning calorimetry (DSC) and tensile
 test. Based on the results, we found that the early thermal-oxidative
 ageing of POM copolymer can be divided into three regions. The first
 region is the initial three days. In this region, some molecular chains
 rearranged, resulting in internal stress relaxation, increased of
 crystallinity degree and grain size due to the perfection of crystal
 structure; both extended chain crystal (ECC) and folded chain crystal
 (FCC) increased and ECC grew faster than FCC. The second region is from 3
 days to 10 days and in this region, chain scission took place in amorphous
 region and led to chemi-crystallization. The last region is after 10 days.
 In this region, the structure and performance of POM copolymer reached a
 stable situation at this stage. In this work, the difference between skin
 and core were also analyzed.

title: Phylogenomics and comparative genomics of two of the largest genera of angiosperms, Piper and Peperomia (Piperaceae)

description: Biological radiations provide unique opportunities to understand the
 evolution of biodiversity. One such radiation is the pepper plant family
 Piperaceae, an early-diverging and mega-diverse lineage that could serve
 as a model to study the diversification of angiosperms. However,
 traditional genetic markers lack sufficient variation for such studies,
 and testing hypotheses on poorly resolved phylogenetic frameworks becomes
 challenging. Limited genomic data is available for Piperaceae, which
 contains two of the largest genera of
 angiosperms, Piper (2,172 species)
 and Peperomia (1,347 species). To address this gap, we
 used genome skimming to assemble a &gt;5kbp nuclear ribosomal DNA
 region and whole plastomes (152-161kbp) from representatives of Piper and
 Peperomia. We conducted phylogenetic and comparative genomic analyses to
 study the evolution of plastomes and investigate the role of hybridization
 in this group. Resulting plastome phylogenies were well resolved and
 highly supported, with a hard incongruence observed between plastome and
 nuclear phylogenetic trees suggesting hybridization in Piper. While all
 plastomes of Piper and Peperomia had
 the same gene content and order, there were informative structural
 differences between them. First, ycf1 was more variable and longer
 in Piper than Peperomia, extending well into
 the small single copy region by thousands of base pairs. We also
 discovered previously unknown structural variation in 14 out of 25 Piper
 taxa, tandem duplication of the trnH-GUG gene resulting in an expanded
 large single copy region. Other early-diverging angiosperms have a
 duplicated trnH-GUG, but the specific rearrangement we found is unique to
 Piper and serves to refine knowledge of relationships among
 early-diverging angiosperms. Our study demonstrates that genome skimming
 is an efficient approach to produce plastome assemblies for comparative
 genomics and robust phylogenies of species-rich plant genera.

title: Similar cost of Hamiltonella defensa in experimental and natural aphid-endosymbiont associations

description: Endosymbiont-conferred resistance to parasitoids is common in aphids, but
 comes at a cost to the host in the absence of parasitoids. In black bean
 aphids (Aphis fabae), costs in terms of reduced lifespan and lifetime
 reproduction were demonstrated by introducing eleven isolates of the
 protective symbiont Hamiltonella defensa into previously uninfected aphid
 clones. Transfection of H. defensa isolates into a common genetic
 background allows to compare the costs of different endosymbiont isolates
 unconfounded by host genetic variation, but has been suggested to
 overestimate the realised costs of the endosymbiont in natural
 populations, because transfection creates new and potentially maladapted
 host-symbiont combinations that would be eliminated by natural selection
 in the field. In this experiment, we show that removing H. defensa
 isolates from their natural host clones with antibiotics results in a
 fitness gain that is comparable to the fitness loss from their
 introduction into two new clones. This suggests that cost estimated from
 transfecting endosymbiont isolates into a shared host genotype does not
 lead to gross overestimates of their realised costs, at least not in the
 two recipient genotypes used here. By comparing our data with data
 reported in previous publications using the same lines, we show that
 symbiont-induced costs may fluctuate over time. Thus, costs estimated
 after extended culture in the laboratory may not always be representative
 of the costs at the time of collection in the field. Finally, we report
 the accidental observation that two isolates from a distinct haplotype of
 H. defensa could not be removed by cefotaxime treatment, while all
 isolates from two other haplotypes were readily eliminated, which is
 suggestive of variation in susceptibility to this antibiotic in H.
 defensa.

title: Latitudinal influence on gametogenesis and host-parasite ecology in a marine bivalve model

description: Reproduction and parasites have significant impacts on marine
 animal populations globally. This study aimed to investigate the
 associative effects of host reproduction and a host-parasite interplay on
 a marine bivalve, along a geographic gradient of latitude. Cockles
 Cerastoderma edule were sampled from five European sites (54°N to 40°N),
 between April 2018 and October 2019. A histological survey provided data
 on trematode (metacercaria and sporocyst life stages), prevalence and
 cockle stage of gametogenesis to assess the influence of a latitudinal
 gradient on both interplays. Sex ratios at the northernmost sites were
 skewed towards females and spawning size was reduced at the lower
 latitudes. Trematode infection did not follow a latitudinal gradient.
 Localised site-related drivers, namely: seawater temperature varied
 spatially, having an impact on cockle-trematode interactions. Spawning was
 related to elevated temperatures at all sites. Prolonged spawning occurred
 at southern latitudes, where seawater temperatures were warmer. Trematode
 prevalence and the impact of trematodes on gametogenesis were found to be
 spatially variable, but not latitudinally. Therefore it is not possible to
 determine the likelihood of boom and bust events in cockles, based on the
 latitudinal location of a population. In terms of sublethal impacts, it
 appeared that energy was allocated to reproduction rather than somatic
 growth in southern populations, with less energy allocated to reproduction
 in the larger, northern cockles. The demonstrated spatial trend of energy
 allocation indicates the potential of a temporal trend of reduced cockle
 growth at northern sites, as a result of warming sea temperatures. This
 awareness of the spatially varying drivers of populations is crucial
 considering the potential for these drivers/inhibitors to be exacerbated
 in a changing marine environment.

title: Data from: Plant diversity effects on plant longevity and their relationships to population stability in experimental grasslands

description: In a 12-year old biodiversity experiment (Jena Experiment) comprising 80
 grassland communities with six levels of plant species richness (1, 2, 4,
 8, 16 and 60 species) and four levels of functional groups richness (1, 2,
 3 and 4 functional groups), we studied populations of 38 dicotyledonous
 forb species (N = 1,683 plant individuals). The sampled individuals
 represented three plant functional groups (legumes, small herbs, tall
 herbs) and two different growth forms (species with long-lived primary
 roots, or clonal species with rhizomes/stolons). We assessed the age of
 plant individuals by means of growth ring analysis and related the age of
 plant populations to their temporal stability in terms of peak
 biomass production.

title: Rare and widespread: Integrating Bayesian MCMC approaches, Sanger sequencing and Hyb-Seq phylogenomics to reconstruct the origin of the enigmatic Rand Flora genus Camptoloma

description: Premise Genera that are widespread but have a geographically discontinuous
 distribution and are represented by few species are intriguing. Did they
 achieve their disjunct distribution recently, or is it ancient in origin?
 Why are they species-poor? The Rand Flora is a continental-scale floristic
 pattern in which closely related species appear co-distributed in isolated
 regions over the edges of Africa and nearby archipelagos. Genus Camptoloma
 (Scrophulariaceae) is the most notable example, comprising three species
 isolated from each other at the ends of the African continent: C.
 canariense in the west, endemic to the Canary Islands; C. lyperiiflorum in
 the east, endemic to the Horn of Africa - Southern Arabia; and C.
 rotundifolia, restricted to Southern Africa. Methods Here, we employed
 Sanger sequencing of nuclear and plastid markers, together with genomic
 target sequencing of 2190 low-copy nuclear genes, to infer interspecies
 relationships and the position of Camptoloma within Scrophulariaceae,
 using supermatrix and multispecies-coalescent approaches. Lineage
 divergence times and ancestral ranges were inferred with Bayesian MCMC
 approaches. Population history was estimated with phylogeographic
 structured coalescent methods. Key Results Our results support C.
 rotundifolia as sister to the disjunct clade formed by C. canariense and
 C. lyperiiflorum. Stem divergence was dated in the Late Miocene, while the
 origin of extant diversification within the genus was inferred as Early
 Pliocene. Conclusions We show that the current disjunct distribution of
 Camptoloma across Africa was likely the result of fragmentation and
 extinction/population bottlenecking events associated to historical
 aridification cycles, consistent with the “climatic refugia” hypothesis.

title: Camera trap photographs of mountain hare Lepus timidus per month Scotland (S1A)

description: The research presented in this paper provides an insight into the
 behavioural ecology of mountain hares on heather moorland in the
 Lammermuir Hills of south east Scotland. We examine the seasonal and diel
 activity patterns using camera traps over a period of 12 months. The rate
 of camera detections was calculated for the different divisions of the 24h
 cycle (daylight, dusk, night and dawn). During autumn and winter (October
 – February), the activity pattern was crepuscular with greater activity at
 dusk than at dawn. Daylight activity was relatively low and there was a
 regular pattern of small peaks of activity during the night. In spring and
 summer (March – September), peaks of crepuscular activity remained evident
 but daylight activity was much more prevalent than during autumn and
 winter, and night activity was lower. We discuss the problematic
 definition of twilight and present an explanation for seasonal changes in
 the pattern of diel activity that is linked to the reproductive cycle of
 the mountain hare.

title: Data from: Testing the occurrence of convergence in the cranio-mandibular shape evolution of living carnivorans

description: Convergence consists in the independent evolution of similar traits in
 distantly related species. The mammalian cranio-mandibular complex
 constitutes an ideal biological structure to investigate ecomorphological
 dynamics and the carnivorans, due to their phenotypic variability and
 ecological flexibility, offer an interesting case-study to explore the
 occurrence of convergent evolution. Here, we applied multiple
 pattern-based metrics to test the occurrence of convergence in the
 cranio-mandibular shape of extant carnivorans. To this aim, we tested for
 convergence in many dietary groups and analysed several cases of
 carnivoran convergence concerning either ecologically equivalent species
 or ecologically similar species of different body sizes described in the
 literature. Our results validate the occurrence of convergence in
 ecologically equivalent species in a few cases (as well as in the case of
 giant and red pandas), but almost never support the occurrence of
 convergent evolution in dietary categories of living carnivorans.
 Therefore, convergent evolution in this clade appears to be a rare
 phenomenon. This is probably the consequence of a complex interplay of
 one-to-many, many-to-one, and many-to-many relationships taking place
 between ecology, biomechanics and morphology.
