title: Data from: Weather-driven dynamics in a dual-migrant system: moths and bats

description: Animal migrations generate large spatial and temporal fluctuations in
 biomass that provide a resource base for many predator-prey interactions.
 These interactions are often driven by continent-scale weather patterns
 and are difficult to study. Few studies have included migratory animals on
 more than a single trophic level or for periods spanning multiple entire
 seasons. We tracked migrations of three species of agricultural pest
 noctuid moths over the 2010-2012 autumn seasons as the moths traveled past
 a large colony of migratory Brazilian free-tailed bats (Tadarida
 brasiliensis) in Texas. Increases in moth abundance, mass of bats, and
 duration of bat activity outside of the cave were correlated with passage
 of cold fronts over the study area and related increases in northerly
 wind. Moth responses to weather patterns varied among species and seasons,
 but overall moth abundances were low in late summer and spiked after one
 or more cold front passages in September and October. Changes in bat mass
 and behavior appear to be consequences of bat migration, as cave use
 transitioned from summer maternity roost to autumn migratory stopover
 sites. Weather-driven migration is at considerable risk from climate
 change, and bat and moth responses to that change may have marked impacts
 on agricultural systems and bat ecosystem services.

title: Data from: Estimating mobile traffic demand using Twitter

description: In this letter, the authors show that structured social media data can act
 as an accurate predictor for wireless data demand patterns at a high
 spatial-temporal resolution. A casestudy is performed on Greater London
 covering a 5000 km2 area. The data used includes over 0.6 million
 geo-tagged Twitter data, over 1 million mobile phone data demand records,
 and U.K. census data. The analysis shows that social media activity
 (Tweets/s n) can accurately predict the long-term traffic demand for both
 the uplink and downlink channels. The relationship between social media
 activity and traffic demand obeys a power law and the model explains for
 over 71%-79% of the variance in real traffic demand. This is a significant
 improvement over existing methods of long-term traffic prediction such as
 census population data (R2 = 0.57). The authors also show that social
 media data can also forward predict short-term traffic demand for up to 2
 h on the same day and for the same time in the following 2-3 days.

title: Data from: Birdsong performance and the evolution of simple (rather than elaborate) sexual signals

description: Sexual signals are often elaborate, due to sexual selection for signals of
 individual quality. Contrary to expectation, however, the elaboration of
 signals such as birdsong is not related to the strength of sexual
 selection across species. With a comparative study across wood warblers
 (family Parulidae), we show a compromise between advertising the
 performance of trills (syllable repetitions) and song complexity, which
 can result in the evolution of simple, rather than elaborate, song.
 Species with higher trill performance evolved simple songs with more
 extensive trilled syntax. This advertises trill performance, but reduces
 syllable diversity in songs. These two traits are commonly sexually
 selected in songbirds, but indexes of sexual selection were not related to
 either in wood warblers. This is consistent with sexual selection
 targeting different traits in different species, sometimes resulting in
 simple signals. We conclude that the evolution of sexual signals can be
 unpredictable when their physiology affords multiple or, as here, opposing
 ways of advertising individual quality.

title: Data from: Influence of environmental heterogeneity on genetic diversity and structure in an endemic southern Californian oak

description: Understanding how specific environmental factors shape gene flow while
 disentangling their importance relative to the effects of geographical
 isolation is a major question in evolutionary biology and a specific goal
 of landscape genetics. Here, we combine information from nuclear
 microsatellite markers and ecological niche modelling to study the
 association between climate and spatial genetic structure and variability
 in Engelmann oak (Quercus engelmannii), a wind-pollinated species with
 high potential for gene flow. We first test whether genetic diversity is
 associated with climatic niche suitability and stability since the Last
 Glacial Maximum (LGM). Second, we use causal modelling to analyze the
 potential influence of climatic factors (current and LGM niche
 suitability) and altitude in the observed patterns of genetic structure.
 We found that genetic diversity is negatively associated with local
 climatic stability since the LGM, which may be due to higher immigration
 rates in unstable patches during favourable climatic periods and/or
 temporally varying selection. Analyses of spatial genetic structure
 revealed the presence of three main genetic clusters, a pattern that is
 mainly driven by two highly differentiated populations located in the
 northern edge of the species distribution range. After controlling for
 geographic distance, causal modelling analyses showed that genetic
 relatedness decreases with the environmental divergence among sampling
 sites estimated as altitude and current and LGM niche suitability. Natural
 selection against non-local genotypes and/or asynchrony in reproductive
 phenology may explain this pattern. Overall, this study suggests that
 local environmental conditions can shape patterns of genetic structure and
 variability even in species with high potential for gene flow and
 relatively small distribution ranges.

title: Data from: Seabird and Louse Coevolution: Complex Histories Revealed by 12S rRNA Sequences and Reconciliation Analyses

description: We investigated the coevolutionary history of seabirds (orders
 Procellariiformes and Sphenisciformes) and their lice (order
 Phthiraptera). Independent trees were produced for the seabirds (tree
 derived from 12S ribosomal RNA (rRNA), isozyme, and behavioral data) and
 their lice (trees derived from 12S rRNA data). Brookâ s parsimony analysis
 (BPA) supported a general history of cospeciation (consistency index =
 0.84, retention index = 0.81). We inferred that the homoplasy in the BPA
 was caused by one intrahost speciation, one potential host switching and
 eight or nine sorting events. Using reconciliation analysis we quantified
 the cost of fitting the louse tree onto the seabird tree. The reconciled
 TreeMap tree postulated one host switching, nine cospeciation, three or
 four intrahost speciation and 11 to 14 sorting events. The number of
 cospeciation events was significantly more than would be expected due to
 chance. The sequence data were used to test for rate heterogeneity for
 both seabirds and lice. The seabird tree showed no significant rate
 heterogeneity over all of its branches whereas part of the louse tree did
 show rate heterogeneity. An examination of the codivergent nodes revealed
 that seabirds and lice have cospeciated synchronously, and that lice have
 evolved at about 5.5 times the rate of seabirds. Sequence data supported
 some of the postulated intrahost speciation events (Halipeurus pre-dated
 the evolution of their present hosts). Sequence data also supported some
 of the postulated host-switching events. These results demonstrate the
 value of sequence data and reconciliation analyses in unraveling complex
 histories between hosts and their parasites.

title: Data from: Geometric morphometric analysis applied to theropod tracks from the lower Cretaceous (Berriasian) of Spain

description: Geometric morphometric methods applied to theropod tracks from the
 Huérteles Formation (Berriasian, Spain) are here shown to be invaluable
 for drawing comparisons between theropod tracks with different
 preservation modes (true tracks, shallow undertracks and natural casts) or
 differing in the preservation of anatomical features (e.g. digital pads).
 Principal components analysis and thin-plate spline methods can
 quantitatively distinguish between the broad groups of tracks in a sample
 and establish the main differences between them. These methods offer a
 promising approach for estimating ichnodiversity, achieved by evaluating
 just the morphology of the tracks independent of other factors such as
 size. The theropod tracks of the Huérteles Formation can be classified
 into two broad groups: minute-to-medium-sized gracile theropod tracks
 (Kalohipus bretunensis) and medium-to-large-sized robust theropod tracks
 (Iberosauripus). The presence of a third group of more gracile
 medium-to-large-sized theropod tracks (Megalosauripus) cannot be proven
 with certainty on the basis of the current data. These results indicate
 that the theropod ichnodiversity of the Huérteles Formation is probably
 lower than that estimated by means of conventional methods alone (e.g.
 qualitative description of the tracks) and that many of the described
 theropod morphotypes may represent extramorphological or ontogenetic
 variations of other morphotypes.

title: Data from: Flash behavior increases prey survival

description: Flash behavior, in which otherwise cryptic prey exhibit conspicuous
 coloration or noise when fleeing from potential predators, has been
 postulated to hinder location of prey once they become stationary. Here,
 using artificial computer-generated prey and humans as visual predators,
 we show that human subjects are more likely to abandon their search for
 prey that flash, compared to continuously cryptic fleeing controls.
 Survivorship of flashing prey was an additional 20% higher than the
 survivorship of continuously cryptic prey, depending on the background
 against which it was depicted. This survivorship advantage was consistent
 regardless of whether prey showed flash colors continuously or
 intermittently during flight. The advantage over continuously cryptic prey
 was highest when the flashing prey was presented first. Likewise, the more
 search areas containing no prey that the volunteers had initially viewed,
 the more likely they were to give up when there was a cryptic prey
 present. Collectively, these three findings indicate that volunteers
 inferred the flashing prey was absent from the search area when they
 failed to see a prey in the same form as they saw it move. Our results
 demonstrate first proof of concept: flash behavior, widely seen in taxa
 from insects to mammals, is an effective antipredator escape mechanism.

title: Data from: Natural and anthropogenic drivers of cub recruitment in a large carnivore

description: Recruitment is a critical parameter governing population dynamics and
 influences population persistence. Understanding the drivers of
 recruitment is therefore important for conservation, especially for
 long-lived mammals such as large carnivores, which have low reproductive
 rates, rendering them prone to extinction. Using cheetahs (Acinonyx
 jubatus) as a model species, I investigated the variation in cub
 recruitment in relation to habitat and the abundance of tourists and
 predators. Per litter, female cheetahs on average raised 1.71 ± 1.35 cubs
 to independence but this varied depending on the presence of open habitat
 and the abundance of tourists, both of which had a negative effect on cub
 recruitment. More specifically, female cheetahs that were mostly found in
 open habitats on average raised 1.69 ± 0.14 cubs per litter to
 independence compared to 3.04 ± 0.26 cubs in denser habitat. Similarly,
 female cheetahs that were exposed to high tourist abundance on average
 raised 0.21 ± 0.72 cubs to independence compared to 2.32 ± 0.11 cubs in
 low tourism areas. Neither lion nor spotted hyaena abundance had an impact
 on the number of cubs that were recruited. Based on these findings, I
 recommend that the importance of a heterogeneous environment should be
 taken into consideration in habitat management, restoration efforts and
 reintroduction programmes. In addition, tourist quotas should be put into
 place in high visitation areas and strict wildlife viewing guidelines,
 such as number of vehicles, tourist behaviour, time spent and distance to
 a sighting, should be enforced. Cub recruitment is an important component
 of species persistence and incorporating these findings could aid
 conservation efforts for species that are increasingly under threat.

title: Data from: A cryptic Allee effect: spatial contexts mask an existing fitness–density relationship

description: Current theories predict that Allee effects should be widespread in
 nature, but there is little consistency in empirical findings. We
 hypothesized that this gap can arise from ignoring spatial contexts (i.e.
 spatial scale and heterogeneity) that potentially mask an existing
 fitness–density relationship: a ‘cryptic’ Allee effect. To test this
 hypothesis, we analysed how spatial contexts interacted with conspecific
 density to influence the fertilization rate of the freshwater mussel
 Margaritifera laevis. This sessile organism has a simple fertilization
 process whereby females filter sperm from the water column; this system
 enabled us to readily assess the interaction between conspecific density
 and spatial heterogeneity (e.g. flow conditions) at multiple spatial
 levels. Our findings were twofold. First, positive density-dependence in
 fertilization was undetectable at a population scale (approx. less than
 50.5 m2), probably reflecting the exponential decay of sperm density with
 distance from the sperm source. Second, the Allee effect was confirmed at
 a local level (0.25 m2), but only when certain flow conditions were met
 (slow current velocity and shallow water depth). These results suggest
 that spatial contexts can mask existing Allee effects.

title: Data from: Timing and number of colonizations but not diversification rates affect diversity patterns in hemosporidian lineages on a remote oceanic archipelago

description: Parasite diversity on remote oceanic archipelagos is determined by the
 number and timing of colonizations, and in-situ diversification rate. In
 this study we compare intra-archipelago diversity of two hemosporidian
 parasite genera, Plasmodium and Leucocytozoon, infecting birds of the
 Mascarene archipelago. Despite the generally higher vagility of Plasmodium
 parasites, we report a much lower diversity of Plasmodium cytochrome-b
 haplotypes in the archipelago compared to Leucocytozoon. Using
 phylogenetic data, we find that this difference in diversity is consistent
 with differences in the timing and the number of colonizations, while
 rates of diversification do not vary significantly between the two genera.
 The prominence of immigration history in explaining current diversity
 patterns highlights the importance of historical contingencies in driving
 disparate biogeographic patterns in potentially harmful blood parasites
 infecting island birds.

title: Data from: Depletion of heterogeneous source species pools predicts future invasion rates

description: Predicting how increasing rates of global trade will result in new
 establishments of potentially damaging invasive species is a question of
 critical importance to the development of national and international
 policies aimed at minimizing future invasions. Centuries of historical
 movement and establishment of invading species may have depleted the
 supply of species available for future invasions, and it has been
 suggested that the problem of invasions will diminish as a result of this.
 However, the extent to which source pool depletion affects future
 invasions remains unclear. Here we describe a mechanistic model that
 captures the simultaneous effects of depletion of source species pools
 along with increases in pathway rates (e.g. imports) to predict future
 numbers of new invasions. We assume that the distribution of species
 abundance within invasion pathways is positively skewed, which is modelled
 using a log-normal distribution. Given their high propagule pressure, the
 most abundant species are likely to invade first, while the many rare
 species are likely to invade only under high pathway volumes. We apply
 this model to the case study of bark beetle, Scolytinae, invasions in the
 USA. Source species pools in Europe and Asia (225 and 655 species of
 Scolytinae, respectively) are much larger than numbers that have
 historically established (16 and 32). Parameterization of the model
 indicates a highly skewed species abundance distribution in the pathway
 and this is confirmed by species frequencies in port inspection records,
 thus explaining why only a small fraction of species has historically
 invaded. Forecasts from the model indicate that with increasing rates of
 imports, more species from these regions are likely to invade in the
 future despite the depletion of the most abundant species from source
 species pools. Previous statistical models tend to underestimate future
 establishments in the presence of increasing import rates due to their
 failure to account for key underlying mechanisms. Policy implications. The
 mechanistic model developed here is widely applicable for predicting
 future invasions of all taxa and provides insights into how increases in
 rates of imports counteract the species pool depletion effect, resulting
 in the continued establishment of new species.

title: Data from: Influence of asymmetrical mating patterns and male reproductive success on the maintenance of sexual polymorphism in Acer pictum subsp. mono (Aceraceae)

description: Populations of Acer species often contain more than three sexual
 phenotypes with very complex sexual polymorphism such as duodichogamy,
 protandry, and protogyny. We investigated whether mating patterns and male
 reproductive success are important factors that maintain sexual
 polymorphism in Acer. Paternity analyses were used to estimate rates of
 outcrossing and disassortative mating, as well as male reproductive
 success, in Acer pictum subsp. mono. A pollen-transfer model was modified
 to investigate whether the unequal ratios of sexual phenotypes were
 associated with observed mating patterns. The mating pattern of Acer
 pictum subsp. mono was mainly outcrossing and disassortative among the
 sexual phenotypes. Although the duodichogamous phenotype showed a
 significant amount of intraphenotypic mating, the frequency did not exceed
 that of disassortative mating. No significant differences in male
 reproductive success were observed among sexual phenotypes. The
 pollen-transfer model demonstrated that sexual phenotype ratios could be
 maintained by the observed mating pattern in the population. The results
 indicated that disassortative mating among the sexual phenotypes can
 maintain sexual polymorphism in A. pictum subsp. mono, and ratios biased
 towards duodichogamy can result from frequent intraphenotypic mating in
 this phenotype.
