title: Species‐specific root proliferation of tree seedlings in tropical litter: do nutrients matter?

description: Litter decomposition mobilizes nutrients that sustain ecosystem
 productivity, but decomposition by-products may also hamper root
 proliferation by phytotoxicity. The aim of this study was to assess the
 litter substrate preferences of tropical tree seedlings in relation to
 litter chemical traits. We characterized 44 litter types (11 species at 4
 decomposition ages; 0, 30, 90 and 180 days) for nutrients (N, P, K, Mg,
 Mn, Na, Fe and Zn) and proximate chemical parameters (cellulose,
 extractive, lignin and C) and tested the effect of such litter materials
 on seedling root growth of Albizia procera, Dalbergia sissoo and
 Terminalia arjuna. A. procera root growth was inhibited by all litter
 types and ages, including conspecific materials, while different
 heterospecific litters had inhibitory or stimulatory effect on D. sissoo
 and T. arjuna root growth, compared to the control. Interestingly,
 inhibitory and stimulatory effects of heterospecific litters significantly
 changed with litter age, although with no clear-cut pattern among target
 species and litter species and age, while conspecific litters consistently
 inhibited root growth when aged, but not when fresh. Litter nutrient,
 extractive, C, cellulose and lignin showed no consistent association with
 root growth of tested plants. A. procera root growth was positively
 associated with Na content and N:P ratio. D. sissoo root growth was
 positively associated to C:N and lignin:N ratios, and negatively to K, Na
 and Zn content. Finally, T. arjuna root was positively associated to
 cellulose and N:P ratio, but negatively to extractive. We conclude that
 studied nutrient, cellulose and lignin do not consistently explain the
 species-specific response of root of tree seedlings to decomposing litter.

title: Seedling traits from root to shoot exhibit genetic diversity and distinct responses to environmental heterogeneity within a tree population

description: Phenotypic diversity within plant species is crucial to shaping
 evolutionary responses of populations and interactions among species, yet
 intraspecific genetic variability notably in roots has attracted little
 attention. Further, evidence for the root−shoot trait synchronisation
 remains inconclusive, narrowing our understanding of the role that
 belowground traits play in local adaptation. We applied broad
 'top-to-toe' phenotyping to a model system whose native
 environmental conditions were simulated in experimental settings. Fifteen
 maternal families of Norway spruce Picea abies from southern
 Finland grew in six combinations of two simulated growing seasons and
 three soil treatments. We scored variation in 25 functional traits,
 including size, architecture and morphology of intact root systems, and
 shoot growth and phenology. Careful phenotyping of roots uncovered five
 trait dimensions, with root size, architecture and morphology forming the
 three largest axes of variation. Dimensions varied in their treatment
 responses. We observed among-family differences in all trait dimensions,
 marking substantial within-population genetic diversity. For example,
 average total root length varied almost twofold among families, but family
 × soil interactions indicated treatment-specific estimates of genetic
 variance. Mirroring root traits, phenotypic plasticity and genetic
 variation characterised shoot growth and phenology. In all, the complete
 phenotypic dataset yielded six trait dimensions, with assorted measures of
 root system and shoot size composing the main axis of variation. Although
 plastic and genetically variable, root architecture and morphology were
 not associated with shoot growth in any treatment. Also phenology and
 root-to-shoot ratio were detached from the primary axis of trait
 variability. Our results demonstrate that complex within-species patterns
 of trait covariation can be observed even locally and that phenotypic
 variation in independent trait dimensions reflecting divergent growth
 strategies is under genetic control. More accurate predictions of
 population and species responses to changes in the environment can be
 achieved when such intraspecific diversity is taken into account.

title: Data from: Whole-chromosome hitchhiking driven by a male-killing endosymbiont

description: Neo-sex chromosomes are found in many taxa, but the forces driving their
 emergence and spread are poorly understood. The female-specific neo-W
 chromosome of the African monarch (or queen) butterfly Danaus chrysippus
 presents an intriguing case study because it is restricted to a single
 ‘contact zone’ population, involves a putative colour patterning
 supergene, and co-occurs with infection by the the male-killing
 endosymbiont Spiroplasma. We investigated the origin and evolution of this
 system using whole genome sequencing. We first identify the ‘BC
 supergene’, a broad region of suppressed recombination across nearly half
 a chromosome, which links two colour patterning loci. Association analysis
 suggests that the genes yellow and arrow in this region control the
 forewing colour pattern differences between D. chrysippus subspecies. We
 then show that the same chromosome has recently formed a neo-W that has
 spread through the contact zone within ~2200 years. We also assembled the
 genome of the male-killing Spiroplasma, and find that it shows perfect
 genealogical congruence with the neo-W, suggesting that the neo-W has
 hitchhiked to high frequency as the male killer has spread through the
 population. The complete absence of female crossing-over in the
 Lepidoptera causes whole-chromosome hitchhiking of a single neo-W
 haplotype, carrying a single allele of the BC supergene, and dragging
 multiple non-synonymous mutations to high frequency. This has created a
 population of infected females that all carry the same recessive colour
 patterning allele, making the phenotypes of each successive generation
 highly dependent on uninfected male immigrants. Our findings show how
 hitchhiking can occur between the unlinked genomes of host and
 endosymbiont, with dramatic consequences.

title: Data from: Trade-offs between morphology and thermal niches mediate adaptation in response to competing selective pressures

description: The effects of climate change - such as increased temperature variability
 and novel predators – rarely happen in isolation, but it is unclear how
 organisms cope with multiple stressors simultaneously. To explore this, we
 grew replicate Paramecium caudatum populations in either constant or
 variable temperatures and exposed half to predation. We then fit thermal
 performance curves (TPCs) of intrinsic growth rate (rmax) for each
 replicate population (N = 12) across seven temperatures (10°C - 38°C).
 TPCs of P. caudatum exposed to both temperature variability and predation
 responded only to one or the other (but not both), resulting in
 unpredictable outcomes. These changes in TPCs were accompanied by changes
 in cell morphology. Although cell volume was conserved across treatments,
 cells became narrower in response to temperature variability and rounder
 in response to predation. Our findings suggest that predation and
 temperature variability produce conflicting pressures on both thermal
 performance and cell morphology. Lastly, we found a strong correlation
 between changes in cell morphology and TPC parameters in response to
 predation, suggesting that responses to opposing selective pressures could
 be constrained by trade-offs. Our results shed new light on how
 environmental and ecological pressures interact to elicit changes in
 characteristics at both the individual and population levels. We further
 suggest that morphological responses to interactive environmental forces
 may modulate population-level responses, making prediction of long-term
 responses to environmental change challenging.

title: Dispatches from the neighborhood watch: using citizen science and field survey data to document color morph frequency in space and time

description: Heritable color polymorphisms have a long history of study in evolutionary
 biology, though they are less frequently examined today than in the past.
 These systems, where multiple discrete, visually identifiable color
 phenotypes co-occur in the same population, are valuable for tracking
 evolutionary change and ascertaining the relative importance of different
 evolutionary mechanisms. Here, we use a combination of citizen science
 data and field surveys in the Great Lakes region of North America to
 identify patterns of color morph frequencies in the eastern gray squirrel
 (Sciurus carolinensis). Using over 68,000 individual squirrel records from
 both large and small spatial scales, we identify the following patterns:
 (1) the melanistic (black) phenotype is often localized but nonetheless
 widespread throughout the Great Lakes region, occurring in all states and
 provinces sampled. (2) In Ohio, where intensive surveys were performed,
 there is a weak but significantly positive association between color morph
 frequency and geographic proximity of populations. Nonetheless, even
 nearby populations often had radically different frequencies of the
 melanistic morph, which ranged from 0 to 96%. These patterns were mosaic
 rather than clinal. (3) In the Wooster, Ohio population, which had over
 eight years of continuous data on color morph frequency representing
 nearly 40,000 records, we found that the frequency of the melanistic morph
 increased gradually over time on some survey routes but decreased or did
 not change over time on others. These differences were statistically
 significant and occurred at very small spatial scales (on the order of
 hundreds of meters). Together, these patterns are suggestive of genetic
 drift as an important mechanism of evolutionary change in this system. We
 argue that studies of color polymorphism are still quite valuable in
 advancing our understanding of fundamental evolutionary processes,
 especially when coupled with the growing availability of data from citizen
 science efforts.

title: Environmental predictors of breeding phenology differ with elevation in a common mountain bird species

description: Temperatures in mountain areas are increasing at a higher rate than the
 Northern Hemisphere land average, but how fauna may respond, in particular
 in terms of phenology, remains poorly understood. The aim of this study
 was to assess how elevation could modify the relationships between climate
 variability (air temperature, snow melt-out date), the timing of plant
 phenology and egg-laying date of the coal tit (Periparus ater). We
 collected 9 years (2011-2019) of data on egg-laying date, spring air
 temperature, snow melt-out date and larch budburst date at two elevations
 (~1300m and ~1900m asl) on a slope located in the Mont-Blanc Massif in the
 French Alps. We found that at low elevation, larch budburst date had a
 direct influence on egg-laying date, while at high altitude snow melt-out
 date was the limiting factor. At both elevations, air temperature had only
 an indirect effect on egg-laying date. Our results shed light on proximate
 drivers of breeding phenology responses to inter-annual climate
 variability in mountain areas, and suggest that factors influencing
 species phenology vary at different elevations. Predicting the future
 responses of species in a climate change context will require testing the
 transferability of models and accounting for non-stationary relationships
 between environmental predictors and the timing of phenological events.

title: Accuracy of genomic selection and long-term genetic gain for resistance to Verticillium wilt in a genetically diverse strawberry population

description: Verticillium wilt, a soil-borne disease caused by the fungal pathogen
 Verticillium dahliae, threatens strawberry (Fragaria × ananassa)
 production worldwide.  The development of resistant cultivars has
 been a challenge since the disease was first reported on strawberry in the
 early 1900s.  The empirical evidence suggests that genetic gains
 have not been negligible and that the genetics of resistance to this
 pathogen is quantitative.  While resistant cultivars have been
 developed, a comparatively small percentage are highly resistant, whereas
 a large percentage are moderately to highly susceptible.  To
 develop insights into the genetics of resistance, we studied a population
 of elite and exotic germplasm accessions (n = 984), including 245
 cultivars developed in public breeding programs since 1854.  We
 observed a full range of phenotypes, from highly susceptible to highly
 resistant.  Broad-sense heritabilities ranged from 0.70 to 0.76,
 whereas narrow-sense genomic heritabilities ranged from 0.33 to
 0.45.  Less than 3% of accessions were classified as highly
 resistant.  Several of the most resistant accessions were
 heirloom cultivars or exotic germplasm accessions developed before the
 introduction of pre-plant soil fumigation in 1960.  We show that
 genetic gains for resistance to Verticillium wilt have been negative over
 the last century and that genomic selection has significant potential to
 increase genetic gains.  Genomic prediction accuracies ranged
 from 0.41 to 0.49 and generally increased as training population diversity
 increased.  Our results suggest that heirloom cultivars and other
 exotic germplasm accessions carry favorable alleles for resistance to
 Verticillium wilt that are not present in modern cultivars.

title: Host suitability and fitness-related parameters in Coptera haywardi ([Hymenoptera]: [Diapriidae]) reared on irradiated Ceratitis capitata ([Diptera]: [Tehritidae]) pupae stemming from the genetic sexing Vienna-8 strain with a temperature-sensitive lethal mutation

description: Coptera haywardi (Ogloblin) is a pupal endoparasitoid of tephritid flies
 with great potential as a biological control agent worldwide as it does
 not attack other Diptera. To reach its full potential, its mass rearing
 needs to be enhanced lowering costs. Here, we focused on the use of
 irradiated pupae of Ceratitis capitata (Wiedemann) stemming from the
 temperature-sensitive lethal (tsl) Vienna-8 genetic sexing strain (=
 CcVienna-8), which is mass-produced in the San Juan Medfly and Parasitoid
 Mass Rearing Facility in Argentina. Exposure of 1- to 2-d-old CcVienna-8
 pupae irradiated at 90 Gy to 6- to 8-d-old C. haywardi females at
 a 10:1 host/parasitoid ratio for 24 h turned out to be highly successful
 for the rearing of this parasitoid. High radiation doses (90–100 Gy) did
 not adversely influence fitness parameters of C. haywardi offspring F1,
 namely lifetime reproductive rates, adult life expectancy, and survival
 time. Demographic parameters in C. haywardi F1 from irradiated
 CcVienna-8 young pupae were improved compared to those values
 re-corded from parasitoid originated from nonirradiated
 CcVienna-8 pupae. These findings will help to enhance
 parasitoid mass rearing for augmentative releases against medfly
 in Argentinean fruit-producing regions.

 statical methods are described in the main text.
