title: Impacts on food web properties of island invertebrate communities vary between different human land uses

description: Human land use is of growing concern for island ecosystems. Besides direct
 impacts on biodiversity, land uses can alter the functioning and structure
 of ecosystems. Central to this are impacts on food webs. The release of
 additional nutrients from human origin, habitat homogenization, or
 environmental filtering due to human land use can change the diet of
 individual consumer species (i.e., their trophic niches) and the
 distribution and overlap of trophic niches within a food web. However, it
 remains largely unclear whether the effects on food web properties vary
 between the different and predominant human land uses present on islands.
 Here, we investigated the impact of two dominant human land uses on small
 oceanic islands (i.e., urban and tourism development) and tested if and
 how different land uses on islands affect food web structure. To
 disentangle human land uses, we investigated islands, which were either
 privately owned by a tourist facility (i.e., exclusively tourism land use)
 or experienced urban development from the local population (i.e., urban
 land use), or remained uninhabited, serving as reference sites free of
 direct land use. Using stable isotope analysis, we show that isotope
 signature, trophic (isotopic) niches, and overall food web properties of
 the investigated island invertebrate communities were significantly
 changed under both land use regimes. While trophic diversity was reduced
 and trophic niche widths increased under tourism land use, the
 investigated food webs showed reduced trophic diversity at the food web
 base and a more uneven trophic niche distribution under urban land use. In
 summary, these findings show that different human land uses can have
 contrasting impacts on oceanic island food webs. As oceanic islands
 experience rapidly growing human land conversion, our results indicate
 that they may also face increasing yet unpredictable long-term changes in
 food web dynamics.

title: Dataset to study the population genomics of introduced Nile tilapia (Oreochromis niloticus (Linnaeus, 1758)) in the Democratic Republic of the Congo: repeated introductions since colonial times with multiple sources

description: During colonial times, Nile tilapia Oreochromis niloticus (Linnaeus, 1758)
 was introduced in non-native parts of the Congo Basin (Democratic Republic
 of the Congo, DRC) for the first time. Currently, it is the most farmed
 cichlid in the DRC, and is present throughout the Congo Basin. Although
 Nile tilapia has been reported as an invasive species, documentation of
 historical introductions into this basin and its consequences are scant.
 Here, we study the genetic consequences of these introductions by
 genotyping 213 Nile tilapia from native and introduced regions, focussing
 on the Congo Basin. Additionally, 48 specimens from 16 other tilapia
 species were included to test for hybridisation. Using RAD sequencing (27
 611 SNPs), we discovered genetic admixture with other tilapia species in
 several morphologically identified Nile tilapia from the Congo Basin,
 stressing their ability to interbreed and the potential threat they cause
 to the genetic integrity of native tilapias. Populations from the Upper
 Congo and those from the Middle-Lower Congo are strongly differentiated.
 The former show genetic similarity with Nile tilapia from the White Nile,
 while specimens from the Benue Basin and Lake Kariba are similar to Nile
 tilapia from the Middle-Lower Congo, suggesting independent introductions
 using different sources. We conclude that the presence of Nile tilapia in
 the Congo Basin results from independent introductions, reflecting the
 dynamic aquaculture history, and that their introduction probably leads to
 genetic interactions with native tilapias, which could lower their
 fitness. We therefore urge to avoid introductions of Nile tilapia in
 non-native regions and to use native tilapias in future aquaculture
 efforts.

 characterized by heterozygosity excess (q-value &lt;0.05) were
 subsequently discarded.

title: Temperature as a likely driver shaping global patterns in mineralogical composition in bryozoans: Implications for marine calcifiers under Global Change

description: The Southern Ocean is showing one of the most rapid responses to
 human-induced global change, thus acting as a sentinel of the effects on
 marine species and ecosystems. Ocean warming and acidification are already
 impacting benthic species with carbonate skeletons, but the magnitude of
 these changes to species and ecosystems remains largely unknown. Here we
 provide the largest carbonate mineralogical dataset to date for Southern
 Ocean bryozoans, which are diverse, abundant and important as carbonate
 producers, thus making them excellent for monitoring the effects of ocean
 warming and acidification. To improve our understanding of how bryozoans
 might respond to ocean warming and acidification, we assess latitudinal
 and seafloor temperature patterns of skeletal mineralogy using bryozoan
 species occurrences together with temperature data for the first time. Our
 findings, combining new mineralogical data with published data from warmer
 regions, show that the proportions of high-Mg calcite and bimineralic
 species increase significantly towards lower latitudes and with increasing
 seawater temperature. These patterns are consistent with the hypothesis
 that seawater temperature is likely a significant driver of variations in
 bryozoan mineralogy at a global scale.
description: We compiled a global dataset
 of 549 bryozoan species using integrated new data from the current study
 with older mineralogy data from bryozoans worldwide. Calcite composition was classified as low
 Mg-calcite (LMC), intermediate Mg-calcite (IMC) and high Mg-calcite
 (HMC). To produce the
 mineral type and skeletal Mg-calcite distribution maps and graphs, we
 downloaded occurrence data for all living bryozoan species from the Global
 Biodiversity Information Facility. Temperatures were extracted for each bryozoan
 occurrence record (latitude and longitude) to assign a temperature value
 using a seafloor temperature dataset produced by Clarke et al.
 (2009). Coefficients of determination for the
 regressions and p-values were calculated to examine relationships between
 latitude and temperature and mineralogical composition.

title: Data from: Plasticity of snowy plover incubation behaviors in response to risks of nest predation

description: Nest predation influences population dynamics and is thought to exert
 strong selection on the evolution of avian life history. Because parental
 behaviors can attract the attention of nest predators, incubating birds
 are predicted to decrease conspicuous behaviors at the nest-site and
 increase incubation constancy when risks of nest predation are high. We
 examined whether snowy plovers Charadrius nivosus responded to
 predator-specific risks of nest predation, using the number of off bouts
 and daily nest attendance (proportion of time spent incubating) as
 responses. We quantified risks using predator-specific hazard rates of
 nest mortality, which varied daily and were based on habitat
 characteristics at each nest. We assessed the influence of
 predator-specific risks of nest mortality on incubation behaviors using an
 individual-centering approach, allowing us to explain variation in
 incubation behaviors within and among breeding pairs. We found increased
 number of off bouts and nest attendance within breeding pairs in response
 to increasing risks of nest predation by foxes (Vulpes spp.) and gulls
 (Larus spp.), but not coyotes (Canis latrans) and common ravens (Corvus
 corax). Among breeding pairs across habitats, we found increased nest
 attendance in response to higher risks of nest predation by foxes, but not
 coyotes, gulls, or ravens. Breeding pairs differed in the amount of
 behavioral plasticity they exhibited in response to risks of nest
 predation. Our results suggest that risks of nest predation differentially
 influence behavioral responses of snowy plovers depending on the predator
 species, and the amount of behavioral plasticity may depend on
 characteristics of breeding adults.

title: Limited seed dispersal shapes fine-scale spatial genetic structure in a Neotropical dioecious large-seeded palm

description: Seed and pollen dispersal contribute to gene flow and shape the genetic
 patterns of plants over fine spatial scales. We inferred fine-scale
 spatial genetic structure (FSGS) and estimated realized dispersal
 distances in Phytelephas aequatorialis, a Neotropical dioecious
 large-seeded palm. We aimed to explore how seed and pollen dispersal shape
 this genetic pattern in a focal population. For this purpose, we genotyped
 138 seedlings and 99 adults with 20 newly developed microsatellite
 markers. We tested if rodent-mediated seed dispersal has a stronger
 influence than insect-mediated pollen dispersal in shaping FSGS. We also
 tested if pollen dispersal was influenced by the density of male palms
 around mother palms in order to further explore this ecological process in
 large-seeded plants. Rodent-mediated dispersal of these large seeds
 occurred mostly over short distances (mean 34.76 ± 34.06 m) while pollen
 dispersal distances were two times higher (mean 67.91 ± 38.29 m). The
 spatial extent of FSGS up to 35 m and the fact that seed dispersal did not
 increase the distance at which male alleles disperse suggest that
 spatially limited seed dispersal is the main factor shaping FSGS and
 contributes only marginally to gene flow within the population. Pollen
 dispersal distances depended on the density of male palms, decreasing when
 individuals show a clumped distribution and increasing when they are
 scattered. Our results show that limited seed dispersal mediated by
 rodents shapes FSGS in P. aequatorialis, while more extensive pollen
 dispersal accounts for a larger contribution to gene flow and may maintain
 high genetic diversity.

title: Macroclimatic and maternal effects on the evolution of reproductive traits in lizards

description: Much of life-history theory rests on fundamental assumptions about
 constraints on the acquisition and allocation of energy to growth and
 reproduction. In general, the allocation of energy to reproduction depends
 on maternal size, which in turn depends on environmental factors
 experienced throughout the life of the mother. Here, we used phylogenetic
 path analyses to evaluate competing hypotheses about the environmental and
 maternal drivers of reproductive traits in lizards. In doing so, we
 discovered that precipitation, rather than temperature, has shaped the
 evolution of the life history. Specifically, environments with greater
 rainfall have enabled the evolution of larger maternal size. In turn,
 these larger mothers produce larger clutches of larger offspring. However,
 annual precipitation has a negative direct effect on offspring size,
 despite the positive indirect effect mediated by maternal size. Possibly,
 the evolution of offspring size was driven by the need to conserve water
 in dry environments, because small organisms are particularly sensitive to
 water loss. Since we found that body size variation among lizards is
 related to a combination of climatic factors, mainly precipitation and
 perhaps primary production, our study challenges previous generalizations
 (e.g., temperature-size rule and Bergmann's rule) and suggests
 alternative mechanisms underlying the evolution of body size.

title: Evolution of sex allocation plasticity in a hermaphroditic flatworm genus

description: Sex allocation theory in simultaneous hermaphrodites predicts that optimal
 sex allocation is influenced by local sperm competition, which occurs when
 related sperm compete to fertilize a given set of eggs. Different factors,
 including the mating strategy and the ability to self-fertilize, are
 predicted to affect local sperm competition and hence the optimal SA.
 Moreover, since the local sperm competition experienced by an individual
 can vary temporally and spatially, this can favour the evolution of sex
 allocation plasticity. Here, using seven species of the free-living
 flatworm genus Macrostomum, we document interspecific variation in sex
 allocation, but neither their mating strategy nor their ability to
 self-fertilize significantly predicted sex allocation among these species.
 Since we also found interspecific variation in sex allocation plasticity,
 we further estimated standardized effect sizes for plasticity in response
 to i) the presence of mating partners (i.e. in isolation vs. with
 partners) and ii) the strength of local sperm competition (i.e. in small
 vs. large groups). We found that self-fertilization predicted sex
 allocation plasticity with respect to the presence of mating partners,
 with plasticity being lower for self-fertilizing species. Finally, we
 showed that interspecific variation in sex allocation is higher than
 intraspecific variation due to sex allocation plasticity. Our study
 suggests that both sex allocation and sex allocation plasticity are
 evolutionarily labile, with self-fertilization predicting the latter in
 Macrostomum.

title: Morphological adaptations linked to flight efficiency and aerial lifestyle determine natal dispersal distance in birds

description: Natal dispersal—the movement from birthplace to breeding location—is often
 considered the most significant dispersal event in an animal’s lifetime.
 Natal dispersal distances may be shaped by a variety of intrinsic and
 extrinsic factors, and remain poorly quantified in most groups,
 highlighting the need for indices that capture variation in dispersal
 among species. In birds, it is hypothesized that dispersal distance can be
 predicted by flight efficiency, which can be estimated using wing
 morphology. However, the use of morphological indices to predict dispersal
 remains contentious and the mechanistic links between flight efficiency
 and natal dispersal are unclear. Here, we use phylogenetic comparative
 models to test whether hand-wing index (HWI, a morphological proxy for
 wing aspect ratio) predicts natal dispersal distance across a global
 sample of 114 bird species. In addition, we assess whether HWI is
 correlated with flight usage in foraging and daily routines. We find that
 HWI is a strong predictor of both natal dispersal distance and a more
 aerial lifestyle. Our results support the use of HWI as a valid proxy for
 relative natal dispersal distance, and also suggest that evolutionary
 adaptation to aerial lifestyles is a major factor connecting flight
 efficiency with patterns of natal dispersal.

 dispersal distances (km) for 114 species of birds. For each species, diet
 classification, migratory strategy, habitat preference, aerial lifestyl

title: Genetic composition and diversity of Arabica coffee in the crop’s center of origin and its impact on four major fungal diseases

description: Conventional wisdom states that genetic variation reduces disease levels
 in plant populations. Nevertheless, crop species have been subject to a
 gradual loss of genetic variation through selection for specific traits
 during breeding, thereby increasing their vulnerability to biotic stresses
 such as pathogens. We explored how genetic variation in Arabica coffee
 sites in southwestern Ethiopia was related to the incidence of four major
 fungal diseases. Sixty sites were selected along a gradient of management
 intensity, ranging from nearly wild to intensively managed coffee stands.
 We used genotyping-by-sequencing of pooled leaf samples (pool-GBS) derived
 from 16 individual coffee shrubs in each of the sixty sites to assess the
 variation in genetic composition (multivariate: reference allele
 frequency) and genetic diversity (univariate: mean expected
 heterozygosity) between sites. We found that genetic composition had a
 clear spatial pattern and that genetic diversity was higher in less
 managed sites. The incidence of the four fungal diseases was related to
 the genetic composition of the coffee stands, but in a specific way for
 each disease. In contrast, genetic diversity was only related to the
 within-site variation of coffee berry disease, but not to the mean
 incidence of any of the four diseases across sites. Given that fungal
 diseases are major challenges of Arabica coffee in its native range, our
 findings that genetic composition of coffee sites impacted the major
 fungal diseases may serve as baseline information to study the molecular
 basis of disease resistance in coffee. Overall, our study illustrates the
 need to consider both host genetic composition and genetic diversity when
 investigating the genetic basis for variation in disease levels.

title: The non-dereliction in evolution: Trophic specialisation drives convergence in the radiation of red devil spiders (Araneae: Dysderidae) in the Canary Islands

description: Natural selection plays a key role in deterministic evolution, as clearly
 illustrated by adaptive radiations. Unlike most spiders, Dysdera species
 display a high variability of cheliceral morphologies, which has been
 suggested to reflect different levels of specialisation to feed on
 isopods. In this study, we integrate geometric morphometrics and
 experimental trials with a fully resolved phylogeny of the highly diverse
 endemic species from the Canary Islands to (1) characterize cheliceral
 morphologies, (2) unravel their dietary function, (3) examine if they
 evolved multiple times independently (4) verify whether convergent
 evolution of morphotypes has occurred and (5) test if specialization could
 lead to evolutionary irreversibility. We show the existence of nine
 cheliceral morphotypes and uncovered their significance for trophic
 ecology. Further, we demonstrate that similar ecomorphs evolved multiple
 times in the archipelago, providing a novel study system to explain how
 convergent evolution and irreversibility due to specialization may be
 combined to shape phenotypic diversification in adaptive radiations.

title: Water residence time and Damköhler number for DOC cycling in global watersheds

description: The relative capacity for watersheds to eliminate or export reactive
 constituents has important implications on aquatic ecosystem ecology and
 biogeochemistry. Removal efficiency depends on factors that affect either
 the reactivity or advection of a constituent within river networks. In
 this dataset, we characterized instream water residence time and Damköhler
 number (Da) for dissolved organic carbon (DOC) uptake in global
 watersheds.
description: Da equals the advection to reaction timescale ratio and thus
 provides a unitless indicator for DOC reaction intensity during transport
 within river networks.The outID column refers to watershed outlet IDs
 corresponding to the Global Reach-Level A Priori Discharge Estimates for
 SWOT (GRADES) river networks. Columns end with "ResT" refer to
 monthly water residence times estimated for global river networks, in the
 unit of hours. Columns end with "Da" to refer to monthly
 Damköhler number estimated for global river networks (unitless).
