title: Data from: Spatial genetic structure in continuous and fragmented populations of Pinus pinaster Aiton

description: Habitat fragmentation, i.e., the reduction of populations into small
 isolated remnants, is expected to increase spatial genetic structure (SGS)
 in plant populations through non-random mating, lower population densities
 and potential aggregation of reproductive individuals. We investigated the
 effects of population size reduction and genetic isolation on SGS in
 maritime pine (Pinus pinaster Aiton) using a combined experimental and
 simulation approach. Maritime pine is a wind-pollinated conifer which has
 a scattered distribution in the Iberian Peninsula due to forest fires and
 habitat fragmentation. Five highly polymorphic nuclear microsatellites
 were genotyped in a total of 394 individuals from two population pairs
 from the Iberian Peninsula, formed by one continuous and one fragmented
 population each. In agreement with predictions, SGS was significant and
 stronger in fragments (Sp=0.020 and Sp=0.026) than in continuous
 populations, where significant SGS was detected for one population only
 (Sp=0.010). Simulations suggested that under fat-tailed dispersal, small
 population size is a stronger determinant of SGS than genetic isolation,
 while under normal dispersal, genetic isolation has a stronger effect. SGS
 was always stronger in real populations than in simulations, except if
 unrealistically narrow dispersal and/or high variance of reproductive
 success were modelled (even when accounting for potential overestimation
 of SGS in real populations due to short-distance sampling). This suggests
 that factors such as non-random mating or selection not considered in the
 simulations were additionally operating on SGS in Iberian maritime pine
 populations.

title: Data from: Coevolution of competing Callosobruchus species does not stabilize coexistence

description: Interspecific resource competition is expected to select for divergence in
 resource use, weakening interspecific relative to intraspecific
 competition, thus promoting stable coexistence. More broadly, because
 interspecific competition reduces fitness, any mechanism of interspecific
 competition should generate selection favoring traits that weaken
 interspecific competition. However, species also can adapt to competition
 by increasing their competitive ability, potentially destabilizing
 coexistence. We reared two species of bean beetles, the specialist
 Callosobruchus maculatus and the generalist C. chinensis, in allopatry and
 sympatry on a mixture of adzuki beans and lentils, and assayed mutual
 invasibility after four, eight, and twelve generations of evolution.
 Contrary to the expectation that coevolution of competitors will weaken
 interspecific competition, the rate of mutual invasibility did not differ
 between sympatry and allopatry. Rather, the invasion rate of C. chinensis,
 but not C. maculatus, increased with duration of evolution, as C.
 chinensis adapted to lentils without experiencing reduced adaptation to
 adzuki beans, and regardless of the presence or absence of C. maculatus.
 Our results highlight that evolutionary responses to interspecific
 competition promote stable coexistence only under specific conditions that
 can be difficult to produce in practice.

title: Data from: Unveiling current guanaco distribution in Chile based upon niche structure of phylogeographic lineages: Andean puna to subpolar forests

description: Niche description and differentiation at broad geographic scales have been
 recent major topics in ecology and evolution. Describing the environmental
 niche structure of sister taxa with known evolutionary trajectories stands
 out as a useful exercise in understanding niche requirements. Here we
 model the environmental niche structure and distribution of the recently
 resolved phylogeography of guanaco (Lama guanicoe) lineages on the western
 slope of the southern Andes. Using a maximum entropy framework, field
 data, and information on climate, topography, human density, and
 vegetation cover, we identify differences between the two subspecies
 (L.g.cacsilensis, L.g.guanicoe) and their intermediate-hybrid lineage,
 that most likely determine the distribution of this species. While aridity
 seems to be a major factor influencing the distribution at the
 species-level (annual precipitation &lt;900 mm), we also document
 important differences in niche specificity for each subspecies, where
 distribution of Northern lineage is explained mainly by elevation (mean =
 3,413 m) and precipitation seasonality (mean = 161 mm), hybrid lineage by
 annual precipitation (mean = 139 mm), and Southern subspecies by annual
 precipitation (mean = 553 mm), precipitation seasonality (mean = 21 mm)
 and grass cover (mean = 8.2%). Among lineages, we detected low levels of
 niche overlap: I (Similarity Index) = 0.06 and D (Schoener’s Similarity
 Index) = 0.01; and higher levels when comparing Northern and Southern
 subspecies with hybrids lineage (I = 0.32-0.10 and D = 0.12-0.03,
 respectively). This suggests that important ecological and/or evolutionary
 processes are shaping the niche of guanacos in Chile, producing
 discrepancies when comparing range distribution at the species-level
 (81,756 km2) with lineages-level (65,321 km2). The subspecies-specific
 description of niche structure is provided here based upon detailed
 spatial distribution of the lineages of guanacos in Chile. Such
 description provides a scientific tool to further develop large scale
 plans for habitat conservation and preservation of intraspecific genetic
 variability for this far ranging South American camelid, which inhabits a
 diversity of ecoregion types from Andean puna to subpolar forests.

title: Data from: A chorus of color: hierarchical and graded information content of rapid color change signals in chameleons

description: Animals rely on information-rich signals to minimize costs associated with
 competition. If fighting ability is linked to stable individual attributes
 (e.g. morphology), the signals that communicate information about such
 ability should be relatively static. Conversely, the temporal variability
 of motivation should favor dynamic threat signals that indicate an
 animal's likelihood of escalating a contest. Though static colors are
 used by many animals to signal quality or fighting ability, the function
 of dynamic color change as a social signal has only recently begun to be
 investigated. Here, we examined the information content of rapid
 physiological color changes displayed by adult male veiled chameleons
 Chamaeleo calyptratus during agonistic interactions by conducting
 experimental trials between live chameleons and standardized,
 experimentally-controlled robochameleon models. Chameleons reliably
 communicated motivation with dynamic color displays – individuals that
 brightened were 14 times more likely to approach the robochameleon than
 non-brightening individuals. Additionally, chameleons with shorter
 latencies to maximum stripe brightness had stronger bites, and those
 displaying brighter, yellower stripes exhibited more aggression. The
 parallels between dynamic color changes and the vocalizations used to
 mediate aggressive interactions in other taxa are numerous. The use of
 particular vocalizations/color changes can signal motivation levels while
 specific signal elements (e.g. pitch, timing, brightness) may be linked to
 fighting ability. Because the complexity and potential information content
 of color signals increases markedly when organisms can display
 context-specific variation in the expression of these ornaments, the study
 of dynamic color signals is a field ripe for the investigation of complex
 visual and signaling strategies.

title: Data from: Influence of oil and gas emissions on ambient atmospheric non-methane hydrocarbons in residential areas of northeastern Colorado

description: The Northern Front Range (NFR) region of Colorado has experienced rapid
 expansion of oil and gas extraction from shale and tight sands reservoirs
 in recent years due to advances in hydraulic fracturing technology, with
 over 24,000 wells currently in operation. This region has also been
 designated as a federal ozone non-attainment area by the U.S. EPA. High
 ozone levels are a significant health concern, as are potential health
 impacts from chronic exposure to primary emissions of non-methane
 hydrocarbons (NMHC) for residents living near wells. From measurements of
 ambient atmospheric NMHC present in residential areas located in close
 proximity to wells in Erie, Colorado, we find that the C2-C5 alkanes are
 enhanced by a factor of 18 - 77 relative to the regional background, and
 present at higher levels than typically found in large urban centers. When
 combined with NMHC observations from downtown Denver and Platteville, it
 is apparent that these compounds are elevated across the NFR, with highest
 levels within the Greater Wattenberg Gas Field. This represents a large
 area source for ozone precursors in the NFR. The BTEX aromatic compounds
 in Erie were comparable to (e.g., benzene) or lower than (e.g., toluene,
 ethylbenzene, xylene) in large urban centers, however, benzene was
 significantly higher in Platteville, and within the range of chronic
 health-based exposure levels. An initial look at comparisons with data
 sets from previous years reveal that ambient levels for oil and
 gas-related NMHC in Erie, as well as further downwind in Boulder, have not
 decreased, but appear to have been increasing, despite tightening of
 emissions standards for the oil and gas industries in 2008.

title: Data from: Genotype-by-genotype interactions between an insect and its pathogen

description: Genotype-by-genotype (G×G) interactions are an essential requirement for
 the coevolution of hosts and parasites, but have only been documented in a
 small number of animal model systems. G×G effects arise from interactions
 between host and pathogen genotypes, such that some pathogen strains are
 more infectious in certain hosts and some hosts are more susceptible to
 certain pathogen strains. We tested for G×G interactions in the gypsy moth
 (Lymantria dispar) and its baculovirus. We infected 21 full-sib families
 of gypsy moths with each of 16 isolates of baculovirus and measured the
 between-isolate correlations of infection rate across host families for
 all pairwise combinations of isolates. Mean infectiousness varied among
 isolates and disease susceptibility varied among host families.
 Between-isolate correlations of infection rate were generally less than
 one, indicating nonadditive effects of host and pathogen type consistent
 with G×G interactions. Our results support the presence of G×G effects in
 the gypsy moth–baculovirus interaction and provide empirical evidence that
 correlations in infection rates between field-collected isolates are
 consistent with values that mathematical models have previously shown to
 increase the likelihood of pathogen polymorphism.

title: Data from: Amount or pattern? Grassland responses to the heterogeneity and availability of two key resources

description: Patterns of resource availability and heterogeneity shape the composition,
 productivity, and dynamics of plant assemblages in a wide variety of
 terrestrial ecosystems. Despite this, the responses of plant assemblages
 to simultaneous changes in the availability and heterogeneity of more than
 a single resource are virtually unknown. To fill this gap, microcosms
 consisting of assemblages formed by Lolium perenne, Plantago lanceolata,
 Anthoxantum odoratum, Holcus lanatus, and Trifolium repens were grown in a
 factorial experiment with the following treatments: nutrient availability
 (NA), water availability (WA), spatial nutrient heterogeneity (NH), and
 temporal water heterogeneity (WH). Assemblages exhibited precise root
 foraging patterns in response to nutrient heterogeneity, which were
 modified by NA and WA. A series of two- and three-way interactions
 involving the four factors evaluated determined biomass production, the
 belowground : aboveground biomass ratio, the patterns of root biomass
 allocation with depth, and the relative contribution to aboveground
 biomass of Lolium and Anthoxanthum. In all cases, these interactions
 explained significant amounts of the variation found in the data. Our
 study demonstrates that considering the interactions between resource
 availability and heterogeneity allows for a refinement of predictions that
 can detectably reduce the error associated with extrapolating from single
 factor analyses.

title: Data from: Interspecies interference and monitoring duration affect detection rates in chew cards

description: Pest monitoring methods should provide unbiased accurate estimates of pest
 densities and locations, while also minimizing time-in-field and costs.
 Recent pest mammal monitoring studies have found that chew cards are more
 effective than conventional mammal monitoring methods, but little
 experimental work has been done to determine optimal experimental duration
 or quantify the risks of saturation by one species biasing detections of
 other species. Here, we used chew cards in three sites within Awarua
 wetland (Southland, New Zealand) to investigate the optimal amount of time
 required to detect targeted pest species (rats, possums and mice), and to
 examine the potential of rats and possums to bias detection rates of other
 species. We found depressed detections of possums and rats where a
 contraspecific had been detected on a card, which is consistent with
 previous studies of a similar duration on interspecies interference. This
 experiment is the first to analyse the rates at which species detections
 accrue over the course of a survey, and we found rat detections lagged
 behind possums for the first four nights. We modelled the effect of survey
 duration and relative rat abundance on the likelihood of further possum
 detections. Duration and rat abundance interacted, meaning there are
 trade-offs to be considered with regard to duration: shorter durations may
 avoid the risk of saturation in areas of high pest density, but risk not
 sampling sparse or neophobic populations. Our data suggest that chew cards
 remain one of the most sensitive pest monitoring tools for rats and
 possums, compared to conventional methods such as tracking tunnels and wax
 tags. In areas of moderate pest densities, we suggest that a duration of
 five nights is optimal for detecting pests. However, in areas of high pest
 density the sensitivity of chew cards may render them unsuitable because
 of saturation and interspecies interference effects.

title: Data from: Conquest of the deep, old and cold: an exceptional limpet radiation in Lake Baikal

description: Lake Baikal is the deepest, oldest and most speciose ancient lake in the
 world. The lake is characterized by high levels of molluscan species
 richness and endemicity, including the limpet family Acroloxidae with 25
 endemic species. Members of this group generally inhabit the littoral
 zone, but have been recently found in the abyssal zone at hydrothermal
 vents and oil-seeps. Here, we use mitochondrial and nuclear data to
 provide a first molecular phylogeny of the Lake Baikal limpet radiation,
 and to date the beginning of intra-lacustrine diversification. Divergence
 time estimates suggest a considerably younger age for the species flock
 compared with lake age estimates, and the beginning of extensive
 diversification is possibly related to rapid deepening and cooling during
 rifting. Phylogenetic relationships and divergence time estimates do not
 clearly indicate when exactly the abyssal was colonized but suggest a
 timeframe coincident with the formation of the abyssal in the northern
 basin (Middle to Late Pleistocene).

title: Data from: Unravelling the role of host plant expansion in the diversification of a Neotropical butterfly genus

description: Background: Understanding the processes underlying diversification is a
 central question in evolutionary biology. For butterflies, access to new
 host plants provides opportunities for adaptive speciation. On the one
 hand, locally abundant host species can generate ecologically significant
 selection pressure. But a diversity of host plant species within the
 geographic range of each population and/or species might also eliminate
 any advantage conferred by specialization. This paper focuses on four
 Melinaea species, which are oligophagous on the family Solanaceae: M.
 menophilus, M. satevis, M. marsaeus, and finally, M. mothone. We examined
 both female preference and larval performance on two host plant species
 that commonly occur in this butterfly’s native range, Juanulloa parasitica
 and Trianaea speciosa, to determine whether the different Melinaea species
 show evidence of local adaptation. Result: In choice experiments, M.
 mothone females used both host plants for oviposition, whereas all other
 species used J. parasitica almost exclusively. In no choice experiment, M.
 mothone was the only species that readily accepted T. speciosa as a larval
 host plant. Larval survival was highest on J. parasitica (82.0 % vs. 60.9
 %) and development took longer on T. speciosa (14.12 days vs. 13.35 days),
 except for M. mothone, which did equally well on both host plants. For all
 species, average pupal weight was highest on J. parasitica (450.66 mg vs.
 420.01 mg), although this difference was least apparent in M. mothone.
 Conclusion: We did not find that coexisting species of Melinaea partition
 host plant resources as expected if speciation is primarily driven by host
 plant divergence. Although M. mothone shows evidence of local adaptation
 to a novel host plant, T. speciosa, which co-occurs, it does not
 preferentially lay more eggs on or perform better on this host plant than
 on host plants used by other Melinaea species and not present in its
 distributional range. It is likely that diversification in this genus is
 driven by co-occurring Müllerian mimics and the resulting predation
 pressure, although this is also likely made possible by greater niche
 diversity as a consequence of plasticity for potential hosts.
