title: Data from: Alarming features: birds use specific acoustic properties to identify heterospecific alarm calls

description: Vertebrates that eavesdrop on heterospecific alarm calls must distinguish
 alarms from sounds that can safely be ignored, but the mechanisms for
 identifying heterospecific alarm calls are poorly understood. While
 vertebrates learn to identify heterospecific alarms through experience,
 some can also respond to unfamiliar alarm calls that are acoustically
 similar to conspecific alarm calls. We used synthetic calls to test the
 role of specific acoustic properties in alarm call identification by
 superb fairy wrens, Malurus cyaneus. Individuals fled more often in
 response to synthetic calls with peak frequencies closer to that of
 conspecific calls, even if other acoustic features were dissimilar to that
 of fairy-wren calls. Further, they then spent more time in cover following
 calls that had both peak frequencies and frequency modulation rates closer
 to natural fairy-wren means. Thus, fairy wrens use similarity in specific
 acoustic properties to identify alarms and adjust a two-stage antipredator
 response. Our study reveals how birds respond to heterospecific alarm
 calls without experience, and together with previous work using playback
 of natural calls shows that both acoustic similarity and learning are
 important for interspecific eavesdropping. More generally, this work
 reconciles contrasting views on the importance of alarm signal structure
 and learning in recognition of heterospecific alarms.

title: Data from: Divergent parasite infections in sympatric cichlid species in Lake Victoria

description: Parasitism has been proposed as a factor in host speciation, as an agent
 affecting coexistence of host species in species rich communities, and as
 a driver of post-speciation diversification. Young adaptive radiations of
 closely related host species of varying ecological and genomic
 differentiation provide interesting opportunities to explore interactions
 between patterns of parasitism, divergence and coexistence of sympatric
 host species. Here, we explored patterns in ectoparasitism in a community
 of 16 fully sympatric cichlid species at Makobe Island in Lake Victoria, a
 model system of vertebrate adaptive radiation. We asked if host niche,
 host abundance or host genetic differentiation explain variation in
 infection patterns. We found significant differences in infections, the
 magnitude of which was weakly correlated with the extent of genomic
 divergence between the host species, but more strongly with the main
 ecological gradient, water depth. These effects were most evident with
 infections of Cichlidogyrus monogeneans, while the only host species with
 a strictly crevice-dwelling niche, Pundamilia pundamilia, deviated from
 the general negative relationship between depth and parasitism. In
 accordance with the Janzen-Connell hypothesis, we also found that host
 abundance tended to be positively associated with infections in some
 parasite taxa. Data on the Pundamilia sister species-pairs from three
 other islands with variable degrees of habitat (crevice) specialization
 suggested that the lower parasite abundance of P. pundamilia at Makobe
 could result from both habitat specialization and the evolution of
 specific resistance. Our results support influences of host genetic
 differentiation and host ecology in determining infections in this diverse
 community of sympatric cichlid species.

title: Data from: Tooth occlusal morphology in the durophagous marine reptiles, Placodontia (Reptilia: Sauropterygia)

description: Placodontia were a group of marine reptiles that lived in shallow
 nearshore environments during the Triassic. Based on tooth morphology it
 has been inferred that they were durophagous, but tooth morphology differs
 among species: placodontoid placodonts have teeth described as
 hemispherical, and the teeth of more highly nested taxa within the
 cyamodontoid placodonts have been described as flat. In contrast, the
 sister taxon to the placodonts, Palatodonta bleekeri, like many other
 marine reptiles, has tall pointed teeth for eating soft-bodied prey. The
 goals of this paper are to quantify these different tooth morphologies and
 compare tooth shape among taxa and with a functionally “optimal” tooth. To
 quantify tooth morphology we measured the radius of curvature (RoC) of the
 occlusal surface by fitting spheres to 3D surface scans or computed
 microtomographic scans. Large RoCs correspond to flatter teeth, while
 teeth with smaller RoCs are pointier; positive RoCs have convex occlusal
 surfaces, and a negative RoC indicates that the occlusal surface of the
 tooth is concave. We found the placodontoid taxa have teeth with smaller
 RoCs than more highly nested taxa, and palatine teeth tend to be flatter
 and closer to the optimal morphology than maxillary teeth. Within one
 well-nested clade, the placochelyids, the rearmost palatine teeth have a
 more complex morphology than the predicted optimal tooth, with an overall
 concave occlusal surface with a small, medial cusp. These findings are in
 keeping with the hypothesis that placodonts were specialized durophagous
 predators with teeth modified to break hard prey items while resisting
 tooth failure.

title: Data from: Testing the link between perceived and actual risk of predation: mosquito oviposition site selection and egg predation by native and introduced fish

description: 1. According to the threat-sensitivity hypothesis, prey avoidance
 behaviour should reflect the magnitude of predation risk. Since predation
 can strongly affect reproduction success, ovipositing females are expected
 to adaptively adjust their predator-avoidance response, or local breeding
 patch selectivity, in accordance with the perceived level of threat posed
 for their progeny by specific predators. However, association between
 avoidance and predation can be disrupted when the prey and the predator
 lack spatio-temporal opportunities to co-evolve, such as in cases of
 non-native predator introductions. 2. We examined the interactions between
 mosquitoes (from the genus Culex) and three species of sympatric
 predaceous freshwater fish, a native cyprinid (Barbus paludinosus), a
 cichlid (Pseudocrenilabrus philander), and an introduced poeciliid, the
 Western mosquitofish (Gambusia affinis). 3. In an outdoor mesocosm
 experiment we quantified patterns of Culex oviposition site selection
 across fish species using free-roaming, caged, and fish-free treatments.
 In a complementary laboratory experiment we tested the effectiveness of
 each fish species as predators of mosquito eggs and larvae. 4. Synthesis
 and applications. We found evidence for: (i) mosquito egg raft predation
 by free- roaming fish; (ii) fish-specific avoidance by ovipositing Culex
 and (iii) a positive association between fish-specific oviposition
 avoidance and fish-specific efficiency as an egg predator. These results
 contribute towards a better understanding of predator-prey coevolution,
 predator-borne cue recognition, and suggest local native fish, the
 Southern mouthbrooder (Pseudocrenilabrus philander), as an alternative to
 Gambusia for the biocontrol of Culex mosquitoes.

title: Data from: Spatial scale and intraspecific trait variability mediate assembly rules in alpine grasslands

description: Assembly of grassland communities has long been scrutinized through the
 lens of functional diversity. Studies generally point to an overwhelming
 influence of climate on observed patterns of functional diversity, despite
 experimental evidence demonstrating the importance of biotic interactions.
 We postulate that this is because most observational studies neglect both
 scale dependencies of assembly processes and phenotypic variation between
 individuals. Here, we test for changes in the importance of abiotic
 filtering and biotic interactions along a stress gradient by explicitly
 accounting for different scales. In addition to quantifying intraspecific
 trait variability (ITV), we also vary the two components of spatial scale,
 including grain (i.e. community size) and extent (i.e. the geographical
 area that defines the species pool). We sampled 20 grassland communities
 in ten sites distributed along a 975-m elevation gradient. At each site,
 we measured seven functional traits for a total of 2020 individuals at
 different spatial grains. We related community functional diversity
 metrics to the main environmental gradient of our study area, growing
 season length (GSL), and assessed the dependence of these relationships on
 spatial grain, spatial extent and ITV. At large spatial grain and extent,
 the imprint of environmental filtering on functional diversity became more
 important with increasing stress (i.e. functional diversity decreased with
 shorter GSL). At small spatial grain and extent, we found a convex
 relationship between functional diversity and GSL congruent with the
 hypothesis that competition is dominant at low-stress levels while
 facilitative interactions are dominant at high-stress levels (i.e. high
 functional diversity at both extremes of the stress gradient).
 Importantly, the effect of intraspecific variability on assembly rules was
 noticeable only at small spatial grain and extent. Synthesis. Our study
 reveals how the combination of abiotic stress and biotic interactions
 shapes the functional diversity of alpine grasslands at different spatial
 scales, and highlights the importance of phenotype variation between
 individuals for community assembly processes at fine spatial scale. Our
 results suggest that studies analysing trait-based assembly rules but
 ignoring ITV and focusing on a single spatial scale are likely to miss
 essential features of community diversity patterns.

title: Data from: Top-down control of carbon sequestration: grazing affects microbial structure and function in salt marsh soils

description: Tidal wetlands have been increasingly recognized as long-term carbon sinks
 in recent years. Work on carbon sequestration and decomposition processes
 in tidal wetlands focused so far mainly on effects of global-change
 factors such as sea-level rise and increasing temperatures. However,
 little is known about effects of land use, such as livestock grazing, on
 organic matter decomposition and ultimately carbon sequestration. The
 present work aims at understanding the mechanisms by which large
 herbivores can affect organic matter decomposition in tidal wetlands. This
 was achieved by studying both direct animal-microbe interactions and
 indirect animal-plant-microbe interactions in grazed and ungrazed areas of
 two long-term experimental field sites at the German North Sea coast. We
 assessed bacterial and fungal gene abundance using quantitative PCR, as
 well as the activity of microbial exo-enzymes by conducting fluorometric
 assays. We demonstrate that grazing can have a profound impact on the
 microbial community structure of tidal wetland soils, by consistently
 increasing the fungi-to-bacteria ratio by 38-42%, and therefore
 potentially exerts important control over carbon turnover and
 sequestration. The observed shift in the microbial community was primarily
 driven by organic matter source, with higher contributions of recalcitrant
 autochthonous (terrestrial) vs. easily degradable allochthonous (marine)
 sources in grazed areas favoring relative fungal abundance. We propose a
 novel and indirect form of animal-plant-microbe interaction: top-down
 control of aboveground vegetation structure determines the capacity of
 allochthonous organic matter trapping during flooding and thus the
 structure of the microbial community. Furthermore, our data provide the
 first evidence that grazing slows down microbial exo-enzyme activity and
 thus decomposition through changes in soil redox chemistry. Activities of
 enzymes involved in C cycling were reduced by 28-40%, while activities of
 enzymes involved in N cycling were not consistently affected by grazing.
 It remains unclear if this is a trampling-driven direct grazing effect, as
 hypothesized in earlier studies, or if the effect on redox chemistry is
 plant mediated and thus indirect. This study improves our process-level
 understanding of how grazing can affect the microbial ecology and
 biogeochemistry of semi-terrestrial ecosystems that may help explain and
 predict differences in C turnover and sequestration rates between grazed
 and ungrazed systems.

title: Data from: The contributions of premating and postmating selection episodes to total selection in sex-role-reversed Gulf pipefish

description: Empirical studies of sexual selection often focus on events occurring
 either before or after mating but rarely both and consequently may fail to
 discern the relative magnitudes and interactions of premating and
 postmating episodes of selection. Here, we simultaneously quantify
 premating and postmating selection in the sex-role-reversed Gulf pipefish
 by using a microsatellite-based analysis of parentage in experimental
 populations. Female pipefish exhibited an opportunity for selection (I) of
 1.64, which was higher than that of males (0.35). Decompositions of I and
 the selection differential on body size showed that over 95% of the
 selection on females arose from the premating phase. We also found
 evidence for a trade-off between selection phases, where multiply mating
 females had significantly lower offspring survivorship compared to singly
 mated females. In males, variance in relative fitness arose mainly from
 the number of eggs received per copulation and a small number of males who
 failed to mate. Overall, our study exemplifies a general approach for the
 decomposition of total selection into premating and postmating phases to
 understand the interplay among components of natural and sexual selection
 that conspire to shape sexually selected traits.

title: Data from: Rediscovering a forgotten canid species

description: Background: The African wolf, for which we herein recognise Canis lupaster
 Hemprich and Ehrenberg, 1832 (Symbolae Physicae quae ex Itinere Africam
 Borealem er Asoam Occidentalem Decas Secunda. Berlin, 1833) as the valid
 species name (we consider the older name Canis anthus Cuvier, 1820 [Le
 Chacal de Sénégal, Femelle. In: Geoffroy St.-Hilaire E, Cuvier F, editors.
 Histoire Naturelle des Mammifères Paris, A. Belin, 1820] a nomen dubium),
 is a medium-sized canid with wolf-like characters. Because of phenotypic
 similarity, specimens of African wolf have long been assigned to golden
 jackal (Canis aureus Linnaeus, 1758 [Systema Naturae per Regna Tria
 Naturae, Secundum Classes, Ordines, Genera, Species, cum Characteribus,
 Differentiis, Synonymis, Locis. Tomus I. Editio decima, reformata, 1758]).
 Results: Here we provide, through rigorous morphological analysis, a
 species description for this taxonomically overlooked species. Through
 molecular sequencing we assess its distribution in Africa, which remains
 uncertain due to confusion regarding possible co-occurrence with the
 Eurasian golden jackal. Canis lupaster differs from all other Canis spp.
 including the golden jackal in its cranial morphology, while
 phylogenetically it shows close affinity to the Holarctic grey wolf (Canis
 lupus Linnaeus, 1758 [Systema Naturae per Regna Tria Naturae, Secundum
 Classes, Ordines, Genera, Species, cum Characteribus, Differentiis,
 Synonymis, Locis. Tomus I. Editio decima, reformata, 1758]). All sequences
 generated during this study clustered with African wolf specimens,
 consistent with previous data for the species. Conclusions: We suggest
 that the estimated current geographic range of golden jackal in Africa
 represents the African wolf range. Further research is needed in eastern
 Egypt, where a hybrid zone between Eurasian golden jackal and African wolf
 may exist. Our results highlight the need for improved studies of
 geographic range and population surveys for the taxon, which is classified
 as ‘least concern’ by the IUCN due to its erroneous identification as
 golden jackal. As a species exclusively distributed in Africa,
 investigations of the biology and threats to African wolf are needed.

title: Data from: Determinants of between-year burrow re-occupation in a colony of the European Bee-eater Merops apiaster

description: Re-occupation of existing nesting burrows in the European bee-eater Merops
 apiaster has only rarely – and if so mostly anecdotically – been
 documented in the literature record, although such behavior would
 substantially save time and energy. In this study, we quantify burrow
 re-occupation in a German colony over a period of eleven years and
 identify ecological variables determining reuse probability. Of 179
 recorded broods, 54% took place in a reused burrow and the overall
 probability that one of 75 individually recognized burrows would be reused
 in a given subsequent year was estimated as 26.4%. This indicates that
 between-year burrow reuse is a common behavior in the study colony which
 contrasts with findings from studies in other colonies. Furthermore,
 burrow re-occupation probability declined highly significantly with
 increasing age of the breeding wall. Statistical separation of within- and
 between-burrow effects of the age of the breeding wall revealed that a
 decline in re-occupation probability with individual burrow age was
 responsible for this and not a selective disappearance of burrows with
 high re-occupation probability over time. Limited duty cycles of
 individual burrows may be caused by accumulating detritus or decreasing
 stability with increasing burrow age. Alternatively, burrow fidelity may
 presuppose pair fidelity which may also explain the observed restricted
 burrow reuse duty cycles. A consequent next step would be to extend our
 within-colony approach to other colonies and compare the ecological
 circumstances under which bee-eaters reuse breeding burrows.
