title: Data from: Do priority effects outweigh environmental filtering in a guild of dominant freshwater macroinvertebrates?

description: Abiotic conditions have long been considered essential in structuring
 freshwater macroinvertebrate communities. Ecological drift, dispersal, and
 biotic interactions also structure communities, and although these
 mechanisms are more difficult to detect, they may be of equal importance
 in natural communities. Here, we hypothesized that in ten
 naturally-replicated headwater streams in Eastern Switzerland,
 locally-dominant amphipod species would be associated with differences in
 environmental conditions. We conducted repeated surveys of amphipods and
 used a hierarchical joint species distribution model to assess the
 influence of different drivers on species co-occurrences. The species had
 unique environmental requirements, but a distinct spatial structure in
 their distributions was unrelated to habitat. Species co-occurred much
 less frequently than predicted by the model, which was surprising because
 laboratory and field evidence suggests they are capable of coexisting in
 equal densities. We suggest that niche preemption may limit their
 distribution and that a blocking effect related to the specific linear
 configuration of streams determines which species colonizes and dominates
 a given stream catchment, thus suggesting a new solution a long-standing
 conundrum in freshwater ecology.

Data is based on surveys done four times, once each season, beginning in Spring 2015 and concluding in Winter 2016. Additional geographic information is included (elevation, land use) about sampling points and catchments; water chemistry measurements from each sampling visit; and a stream substrate habitat assessment from each sampling visit.

title: Data from: Estimating genome-wide heterozygosity: effects of demographic history and marker type

description: Heterozygosity–fitness correlations (HFCs) are often used to link
 individual genetic variation to differences in fitness. However, most
 studies examining HFCs find weak or no correlations. Here, we derive broad
 theoretical predictions about how many loci are needed to adequately
 measure genomic heterozygosity assuming different levels of identity
 disequilibrium (ID), a proxy for inbreeding. We then evaluate the expected
 ability to detect HFCs using an empirical data set of 200 microsatellites
 and 412 single nucleotide polymorphisms (SNPs) genotyped in two
 populations of bighorn sheep (Ovis canadensis), with different demographic
 histories. In both populations, heterozygosity was significantly
 correlated across marker types, although the strength of the correlation
 was weaker in a native population compared with one founded via
 translocation and later supplemented with additional individuals. Despite
 being bi-allelic, SNPs had similar correlations to genome-wide
 heterozygosity as microsatellites in both populations. For both marker
 types, this association became stronger and less variable as more markers
 were considered. Both populations had significant levels of ID; however,
 estimates were an order of magnitude lower in the native population. As
 with heterozygosity, SNPs performed similarly to microsatellites, and
 precision and accuracy of the estimates of ID increased as more loci were
 considered. Although dependent on the demographic history of the
 population considered, these results illustrate that genome-wide
 heterozygosity, and therefore HFCs, are best measured by a large number of
 markers, a feat now more realistically accomplished with SNPs than
 microsatellites.

title: Data from: Biogeographic variation in skull morphology across the Kra Isthmus in dusky leaf monkeys

description: Despite the growing literature on the underlying factors of geographical
 phenotypic variation, little is known about how and to what extent
 biogeographical barriers in Southeast Asia have shaped morphological
 variation in primates. We aimed to investigate the geographical variations
 in skull morphology in dusky leaf monkeys by decomposing them into clinal
 (latitudinal), non-clinal spatial (discrete difference between regions
 north and south of the Isthmus of Kra), and environment-related
 components. We applied geometric morphometrics to measure 53 adult male
 specimens from 36 localities, covering the regions both north and south of
 the Isthmus of Kra. A linear model was used to test the effects of region
 (north vs. south of the Isthmus of Kra), latitude, and environmental
 factors (temperature and rainfall) on the size and shape of skulls. A part
 of variation in skull shape differed moderately between the regions in the
 north and south of the Isthmus of Kra, and this difference cannot be
 explained by latitudinal and environmental factors. However, for size and
 the majority of variations in shape, we detected limited contributions of
 region and the two environmental factors. Shape differentiation that was
 unexplained by latitudinal and environmental factors suggests that dusky
 leaf monkeys may have experienced a population division due to habitat
 constriction around the Isthmus of Kra. However, this divergence probably
 has been obscured by subsequent gene flow between populations after
 habitat recovery.

title: Data from: New DNA data from a Transthyretin nuclear intron suggest an Oligocene to Miocene diversification of living South America opossums (Marsupialia: Didelphidae).

description: Phylogenetic relationships of 19 species of didelphid marsupials were
 studied using two nuclear markers, the non-coding transthyretin intron 1
 (TTR) and the coding interphotoreceptor retinoid binding protein exon 1
 (IRBP), and two mitochondrial genes, the protein-coding cytochrome b
 (cyt-b) and the structural 12S ribosomal DNA (12S rDNA). Evolutionary
 dynamics of these four markers were compared to each other, revealing the
 appropriate properties presented by TTR intron 1 together with its well
 supported and resolved phylogenetic signal. Nuclear markers supported the
 monophyly of medium and large-sized opossums Metachirus+(Chironectes,
 Lutreolina, Didelphis, Philander), and the paraphyly of mouse-sized
 opossums, with the genera Gracilinanus, Thylamys, and Marmosops as a
 sister group to medium and large-sized didelphids. Conflicting branching
 patterns between mitochondrial and nuclear data involved the phylogenetic
 position of Marmosa-Micoureus-Monodelphis relative to other mouse-sized
 opossums. Nuclear phylogenetic inferences among genera were confirmed by
 the presence of synapomorphic indels observed in TTR intron 1. A Bayesian
 relaxed molecular clock dating of didelphid evolution using nuclear
 markers estimated their origin in the Middle Eocene (39.8 million years
 ago), with subsequent diversification during the Oligocene (Deseadan) and
 Miocene.

title: Data from: Ablation of insulin-producing cells prevents obesity but not premature mortality caused by a high-sugar diet in Drosophila

description: Ageing can be modulated by genetic as well as nutritional interventions.
 In female Drosophila melanogaster, lifespan is maximized at intermediate
 concentrations of sucrose as the carbohydrate source, and yeast as the
 protein source. Dampening the signal through the insulin/IGF signalling
 (IIS) pathway, by genetic ablation of median neurosecretory cells (mNSCs)
 that produce insulin-like peptides, extends lifespan and counteracts the
 detrimental effects of excess yeast. However, how IIS reduction impacts
 health on a high-sugar diet remains unclear. We find that, while the
 ablation of the mNSCs can extend lifespan and delay the age-related
 decline in the health of the neuromuscular system irrespective of the
 amount of dietary sugar, it cannot rescue the lifespan-shortening effects
 of excess sugar. On the other hand, ablation of mNSCs can prevent adult
 obesity resulting from excess sugar, and this effect appears independent
 from the canonical effector of IIS, dfoxo. Our study indicates that while
 treatments that reduce IIS have anti-ageing effects irrespective of
 dietary sugar, additional interventions may be required to achieve full
 benefits in humans, where excessive sugar consumption is a growing
 problem. At the same time, pathways regulated by IIS may be suitable
 targets for treatment of obesity.

title: Data from: Parasitic versus nutritional regulation of natural fish populations

description: 1. Although parasites are expected to affect their host’s fitness,
 quantitative proof for impacts of parasitism on wild populations is
 hampered by confounding environmental factors, including dietary resource.
 2. Herein, we evaluate whether the physiological conditions of European
 perch (Perca fluviatilis) in three large peri-alpine lakes (Geneva,
 Annecy, and Bourget) depend on (a) the nutritional status of the juvenile
 fish, as revealed by stable isotope and fatty acid compositions, (b) the
 prevalence of the tapeworm Triaenophorus nodulosus, a parasite transmitted
 to perch through copepod preys, or (c) interactive effects of both
 factors. 3. At the scale of lake populations, the deficit in growth and
 fat storage of juvenile perch during their first summer coincides with a
 high parasite prevalence and also a low quality of dietary resource. 4.
 Yet, at the individual level, parasites had no evident effect on the
 growth of the juvenile perch, while impacts on fat storage appeared only
 at the highest prevalence of the most infected lake. Fatty acid and stable
 isotope analyses of fish tissue do not reveal any impact of T. nodulosus
 on diet, physiology, and feeding behaviour of fish within lakes. 5.
 Overall, we found a low impact of parasitism on the physiological
 condition and trophic status of juvenile perch at the end of their first
 summer. We find instead that juvenile perch growth and fat storage, both
 factors tied to their winter survival, are under strong nutritional
 constraints. 6. However, the coinciding nutritional constraints and
 parasite prevalence of perch juveniles in these three lakes may result
 from the indirect effect of lake nutrient concentrations, which, as a
 major control of zooplankton communities, simultaneously regulate both the
 dietary quality of fish prey and the host–parasite encounter rates.

title: Data from: The role of temperature and dispersal in moss-microarthropod community assembly after a catastrophic event

description: There is a clear crisis in the maintenance of biodiversity. It has been
 generated by a multitude of factors, notably habitat loss, now compounded
 by the effects of climate change. Predicted changes in climate include
 increased severity and frequency of extreme climatic events. To manage
 landscapes, an understanding of the processes that allow recovery from
 these extreme events is required. Understanding these landscape-scale
 processes of community assembly and disassembly is hindered by the large
 scales at which they operate. Model systems provide a means of studying
 landscape scale processes at tractable scales. Here, we assess the
 combined effects of temperature and habitat-patch isolation on assembly of
 naturally-diverse moss microarthropod communities after a high-temperature
 event. We show that community assembly depends on temperature and on
 degree of habitat isolation. Heated communities were heavily dominated in
 abundance by two species, one of them relatively large. The resulting
 size-structure is unlike that seen in the field. Community composition in
 habitat fragments appears to also have been influenced by the source pool
 of recolonising fauna. Our results highlight the value of dispersal in
 disturbed landscapes and the potential for habitat connectivity to buffer
 communities from the effects of climate change.

title: Data from: The effect of pollination mode on seed performance of Gentiana lutea: a laboratory evaluation of seed germinability

description: Gentiana lutea L. (yellow gentian, Gentianaceae) is a protected orophyte
 of central and southern Europe, mainly threatened by the uncontrolled
 collection of its rhizome, used in traditional medicine and for liquor
 production. The species is self-compatible, but outcrossing mediated by
 pollinators is needed to obtain a viable progeny. In this study, we
 considered five natural populations belonging to the four subspecies of G.
 lutea. We performed controlled pollinations in the field (self- versus
 cross-pollination) followed by seed germination tests in laboratory
 conditions, adding a solution of gibberellic acid, in order to evaluate
 the seed performance. A cumulative index of inbreeding depression was
 calculated considering maternal reproductive output as well as seed
 performance traits. Seed weight and seed germination performance was
 similar between seeds resulting from naturally pollinated and
 pollen-augmented flowers and higher compared to selfed flowers,
 highlighting a disadvantage of selfing and the importance of cross-pollen
 transfer in natural conditions. However, in the small and isolated
 population of G. lutea subsp. symphyandra on Mt Grande we found a general
 reduction in seed germination rate, likely due to increased selfing or
 mating among close relatives as a consequence of a severe bottleneck. We
 discuss our results with regards to implications for conservation
 practices.

title: Data from: Discrete colour polymorphism in the tawny dragon lizard (Ctenophorus decresii) and differences in signal conspicuousness among morphs

description: Intraspecific colour variation is common in nature and can vary from the
 coexistence of discrete colour variants in polymorphic species to
 continuous variation. Whether coloration is continuous or discrete is
 often ambiguous and many species exhibit a combination of the two. The
 nature of the variation (discrete or continuous) has implications for both
 the genetic basis of the colour variation and the evolutionary processes
 generating and maintaining it. Consequently, it is important to qualify
 the existence of discrete morphs, particularly in relation to the
 animal's visual system. In this study, we quantified male throat
 colour variation in Ctenophorus decresii tawny dragon lizard and tested
 for morphological and ecological correlates of the colour variants. We
 confirmed that discrete throat colour morphs can be defined based on
 colour and pattern analyses independent of the human visual system. We
 also found that the colour variants differed in their conspicuousness from
 the background, to the lizard's visual system, which has implications
 for signalling. However, the morphs did not differ in morphology or
 microhabitat use, which suggests that these characteristics are not
 involved in the evolutionary maintenance of the polymorphism.

title: Data from: Paleoenvironmental and paleobiological origins of coccolithophorid genus Watznaueria emergence during the Late Aalenian-Early Bajocian

description: The latest Aalenian–early Bajocian time interval (ca. 171-169 Ma) is
 marked by a global reorganization of oceanic plates with the Central
 Atlantic opening and the formation of the Pacific plate. This time
 interval is also marked by a global geochemical perturbation of δ13C with
 a negative excursion at the Aalenian/Bajocian boundary and a positive
 excursion during the early Bajocian. Evolutionary diversifications of
 marine invertebrate taxa, namely ammonites, radiolarians, and
 coccolithophorids, are recorded at that time. Concerning
 coccolithophorids, this interval witnesses the diversification and
 expansion of the most successful Mesozoic genus: Watznaueria. In this
 study, we explore the potential environmental, ecological, and biological
 forcing at the origin of Watznaueria diversification and its effect on the
 coccolith assemblages through quantification of the absolute and relative
 abundances of calcareous nannofossils in two Middle Jurassic key sections:
 Cabo Mondego (Portugal) and Chaudon-Norante (France). In both sections, we
 find an increase in nannofossil absolute abundance and flux at the
 beginning of the lower Bajocian, coeval with an increase in absolute and
 relative abundances of Watznaueria spp., followed by a plateau in the
 middle and upper part of the lower Bajocian. The increase of Watznaueria
 spp. is synchronous with a decrease in relative abundance of other major
 coccolith taxa, whereas the absolute abundance of these species did not
 decrease. During the climatically driven early Bajocian eutrophication
 event, Watznaueria spp. integrated into the calcareous nannoplankton
 community in two successive evolutionary steps involving first W.
 contracta and W. colaccicchii, and second W. britannica and W. aff.
 manivitiae. Step 1 was driven by an increase in niche carrying capacities
 linked to the early Bajocian eutrophication. Step 2 was driven by specific
 adaptation of the newly evolved Watznaueria species to bloom in
 nutrient-rich environments not exploited before. These evolutionary events
 have initiated the 100-Myr reign of Watznaueria over the calcareous
 nannoplankton community.

title: Data from: Plant-fungal symbiosis affects litter decomposition during primary succession

description: Microbial symbionts of plants can affect decomposition by altering the
 quality or quantity of host plant tissue (substrate) or the
 micro-environment where decomposition occurs (conditioning). In C3
 grasses, foliar fungal endophytes (Clavicipitaceae) can increase plant
 resistance to drought and/or produce alkaloids that reduce herbivory –
 effects that may also influence host litter composition and subsequent
 litter decomposition. We studied the effect of the endophyte Epichloë sp.
 on litter decomposition in the Great Lakes dunes (USA) using a reciprocal
 design altering endophyte presence/absence in both American beachgrass
 Ammophila breviligulata substrate (litter bags) and its conditioning of
 the decomposition microenvironment. Symbiont treatments were crossed with
 rain-out shelters that altered growing season precipitation. The first
 year of decomposition, senesced leaf substrate from A. breviligulata with
 Epichloë decomposed 21% faster than endophyte-free substrate. By the third
 year, conditioning by live symbiotic plants reduced cumulative
 decomposition by 33% compared to plots planted with endophyte-free plants.
 Of the traits we examined – litter quantity, C:N ratio, mineral
 composition, fungal colonization, and carbon chemistry – increased litter
 quantity via greater tiller production was the primary trait shift
 associated with endophyte symbiosis. Epichloë in A. breviligulata litter
 also altered litter nitrogen decomposition dynamics, as evidenced by lower
 nitrogen and protein content in decomposed tissue from plants that hosted
 the endophyte. Differences in initial litter quality and subsequent
 colonization by saprotrophic fungi were ruled out as key drivers. Altered
 precipitation had negligible effects on decomposing processes in the
 dunes. Grass–Epichloë symbiosis altered nutrient cycling through
 increasing the rate of litter decomposition when present in the litter and
 through reducing litter decomposition by conditioning the decomposition
 microenvironment. Epichloë are widespread symbionts of grasses. Thus,
 their effects on decomposition could be an important, but often
 overlooked, driver of nutrient cycling in grass-dominated ecosystems.
