title: Data from: Ensemble approach for potential habitat mapping of invasive Prosopis in Turkana, Kenya

description: Aim: Prosopis spp. are an invasive alien plant species native to the
 Americas and well adapted to thrive in arid environments. In Kenya,
 several remote‐sensing studies conclude that the genus is well established
 throughout the country and is rapidly in‐ vading new areas. This research
 aims to model the potential habitat of Prosopis spp. by using an ensemble
 model consisting of four species distribution models. Furthermore,
 environmental and expert knowledge‐based variables are assessed. Location:
 Turkana County, Kenya. Methods: We collected and assessed a large number
 of environmental and expert knowl‐ edge‐based variables through variable
 correlation, collinearity, and bias tests. The varia‐ bles were used for
 an ensemble model consisting of four species distribution models: (a)
 logistic regression, (b) maximum entropy, (c) random forest, and (d)
 Bayesian networks. The models were evaluated through a block
 cross‐validation providing statistical measures. Results: The best
 predictors for Prosopis spp. habitat are distance from water and built‐up
 areas, soil type, elevation, lithology, and temperature seasonality. All
 species distribution models achieved high accuracies while the ensemble
 model achieved the highest scores. Highly and moderately suitable Prosopis
 spp. habitat covers 6% and 9% of the study area, respectively. Main
 conclusions: Both ensemble and individual models predict a high risk of
 continued invasion, confirming local observations and conceptions.
 Findings are valuable to stake‐ holders for managing invaded area,
 protecting areas at risk, and to raise awareness.

title: Data from: Evolutionary consequence of a change in life cycle complexity: a link between precocious development and evolution towards female-biased sex allocation in a hermaphroditic parasite

description: The evolutionary consequences of changes in the complex life cycles of
 parasites are not limited to the traits that directly affect transmission.
 For instance, mating systems that are altered due to precocious sexual
 maturation in what is typically regarded as an intermediate host may
 impact opportunities for outcrossing. In turn, reproductive traits may
 evolve to optimize sex allocation. Here we test the hypothesis that sex
 allocation evolved towards a more female-biased function in populations of
 the hermaphroditic digenean trematode Alloglossidium progeneticum that can
 precociously reproduce in their second hosts. In these precocious
 populations, parasites are forced to self-fertilize as they remain
 encysted in their second hosts. In contrast, parasites in obligate 3-host
 populations have more opportunities to outcross in their third host. We
 found strong support that in populations with precocious development,
 allocation to male resources was greatly reduced. We also identified a
 potential phenotypically plastic response in a body size-sex allocation
 relationship that may be driven by the competition for mates. These
 results emphasize how changes in life cycle patterns that alter mating
 systems can impact the evolution of reproductive traits in parasites.

title: Data from: The effect of excluding juveniles on apparent adult olive baboons (Papio anubis) social networks

description: In recent years there has been much interest in investigating the social
 structure of group living animals using social network analysis. Many
 studies so far have focused on the social networks of adults, often
 excluding younger, immature group members. This potentially may lead to a
 biased view of group social structure as multiple recent studies have
 shown that younger group members can significantly contribute to group
 structure. As proof of the concept, we address this issue by investigating
 social network structure with and without juveniles in wild olive baboons
 (Papio anubis) at Gashaka Gumti National Park, Nigeria. Two social
 networks including all independently moving individuals (i.e., excluding
 dependent juveniles) were created based on aggressive and grooming
 behaviour. We used knockout simulations based on the random removal of
 individuals from the network in order to investigate to what extent the
 exclusion of juveniles affects the resulting network structure and our
 interpretation of age-sex specific social roles. We found that juvenile
 social patterns differed from those of adults and that the exclusion of
 juveniles from the network significantly altered the resulting overall
 network structure. Moreover, the removal of juveniles from the network
 affected individuals in specific age-sex classes differently: for example,
 including juveniles in the grooming network increased network centrality
 of adult females while decreasing centrality of adult males. These results
 suggest that excluding juveniles from the analysis may not only result in
 a distorted picture of the overall social structure but also may mask some
 of the social roles of individuals belonging to different age-sex classes.

title: Data from: Matching symbiotic associations of an endangered orchid to habitat to improve conservation outcomes

description: Background and Aims: An understanding of mycorrhizal variation, orchid
 seed germination temperature and the effect of co-occurring plant species
 could be critical for optimising conservation translocation of endangered
 plants with specialised mycorrhizal associations. Methods: Focussing on
 the orchid Thelymitra epipactoides we isolated mycorrhizal fungi from ten
 plants within each of three sites; Shallow Sands Woodland (SSW), Damp
 Heathland (DH) and Coastal Heathland Scrub (CHS). Twenty-seven fungal
 isolates were tested for symbiotic germination under three temperature
 ranges: 12-16°C, 16-24°C or 27°C. Fungi were sequenced using the ITS,
 nLSU, 28S and mitochondrial regions. Orchids were grown to maturity and
 co-planted with each of ten associated plant species with tuber width
 measured at 12 months after co-planting. Key Results: Two Tulasnella
 fungal lineages were isolated and identified by phylogenetic analyses,
 OTU1 and “T. asymmetrica”. Fungal lineages were specific to sites and did
 not co-occur. OTU1 (from the SSW site), germinated seed predominately at
 12-16°C (typical of autumn-winter temperature) whereas “T. asymmetrica”
 (from the DH and CHS sites), germinated seed across all three temperature
 ranges. There was no difference in the growth of adult orchids germinated
 with different OTUs. There was a significant reduction in tuber size of T.
 epipactoides when co-planted with six of the commonly co-occurring plant
 species. Conclusions: We found orchid fungal lineages and their
 germination temperature can change with habitat and established that
 translocation sites can be optimised with knowledge of co-occurring plant
 interactions. For conservation translocations, particularly under a
 changing climate, we recommend plants should be grown with mycorrhizal
 fungi tailored to the recipient site.

title: Data from: Multi-allelic exact tests for Hardy-Weinberg equilibrium that account for gender

description: Statistical tests for Hardy-Weinberg equilibrium are important elementary
 tools in genetic data analysis. X-chromosomal variants have long been
 tested by applying autosomal test procedures to females only, and gender
 is usually not considered when testing autosomal variants for equilibrium.
 Recently, we proposed specific X-chromosomal exact test procedures for
 bi-allelic variants that include the hemizygous males, as well as
 autosomal tests that consider gender. In this paper we present the
 extension of the previous work for variants with multiple alleles. A full
 enumeration algorithm is used for the exact calculations of triallelic
 variants. For variants with many alternate alleles we use a permutation
 test. Some empirical examples with data from the 1000 genomes project are
 discussed.

title: Data from: Will a small randomly-assembled community be feasible and stable?

description: How likely is that few species can randomly assemble into a feasible and
 stable community? Some studies have answered that as long as the community
 is feasible, it will nearly always be stable. In contrast, other studies
 have answered that the likelihood is almost null. Here, we show that the
 origin of this debate has been the underestimation of the association of
 the parameter space of intrinsic growth rates with the feasibility and
 stability properties of small randomly-assembled communities. In
 particular, we demonstrate that not all parameterizations and sampling
 distributions of intrinsic growth rates lead to the same probabilities of
 stability and feasibility, which could mistakenly lead to under or
 overestimate the stability properties of feasible communities.
 Additionally, we find that stability imposes a filtering of species
 abundances towards more even distributions in small feasible
 randomly-assembled communities. This indicates that the stability of
 feasible communities is inherently linked to the starting distribution of
 species abundances, a characteristic that many times has been ignored, but
 should be incorporated in manageable lab and field experiments. Overall,
 these findings show that a more systematic exploration of the feasible
 parameter space is necessary to derive general conclusions about the
 stability properties of ecological communities

title: Data from: Nutritional status and nosocomial infections among adult elective surgery patients in a Mexican tertiary care hospital

description: Background: Controversy exists as to whether obesity constitutes a
 risk-factor or a protective-factor for the development of nosocomial
 Infection (NI). According to the obesity-paradox, there is evidence that
 moderate obesity is a protective-factor. In Mexico few studies have
 focused on the nutritional status (NS) distribution in the hospital
 setting. Objectives: The aim of this study was to estimate the
 distribution of NS and the prevalence of nosocomial infection NI among
 adult elective surgery (ES) patients and to compare the clinical and
 anthropometric characteristics and length of stays (LOS) between obese and
 non-obese patients and between patients with and without NI. Methods: We
 conducted a cross-sectional study with a sample (n = 82) adult ES patients
 (21–59 years old) who were recruited from a tertiary-care hospital. The
 prevalences of each NS category and NI were estimated, the assessments
 were compared between groups (Mann-Whitney, Chi-squared or the
 Fisher's-exact-test), and the association between preoperative
 risk-factors and NI was evaluated using odds ratios. Results: The
 distribution of subjects by NS category was: underweight (3.66%),
 normal-weight (28.05%), overweight (35.36%), and obese (32.93%). The
 prevalence of NI was 14.63%. The LOS was longer (p&lt;0.001) for the
 patients who developed NI. The percentages of NI were: 33.3% in
 underweight, 18.52% in obese, 17.39% in normal-weight, and 6.90% in
 overweight patients. Conclusion: The prevalence of overweight and obesity
 in adult ES patients is high. The highest prevalence of NI occurred in the
 underweight and obese patients. The presence of NI considerably increased
 the LOS, resulting in higher medical care costs.

title: Data from: MHC variation and blood parasites in resident and migratory populations of the common yellowthroat

description: Genes of the major histocompatibility complex (MHC) are a critical part of
 the adaptive immune response, and the most polymorphic genes in the
 vertebrate genome, especially in passerine birds. This diversity is
 thought to be influenced by exposure to pathogens which can vary in
 relation to numerous factors. Migratory behaviour may be a particularly
 important trait to consider because migratory birds are exposed to a
 greater number of different pathogens and parasites at both breeding (i.e.
 temperate) and overwintering (i.e. tropical and subtropical) areas, as
 well as at stopover sites during migration. Thus, migrants are predicted
 to have greater MHC diversity than residents. We compared MHC variation,
 at both class I and II, and levels of haemosporidian infection between one
 resident and two migratory populations of the common yellowthroat
 (Geothlypis trichas). We found that residents were less likely to be
 infected with haemosporidian parasites and had lower MHC diversity at
 class I; however, variation at MHC class II was greater in residents than
 migrants, contrary to our prediction. These patterns were not likely to be
 caused by differences in population demography as genome-wide
 heterozygosity (based on 9225 single-nucleotide polymorphisms) was high in
 all three populations and not correlated with MHC variation. Our different
 results for MHC class I and II suggest that studies of immune gene
 variation in relation to life history need to consider that there could be
 different selection pressures arising from intracellular (class I) and
 extracellular (class II) pathogens in different populations.

title: Data from: High opportunity for postcopulatory sexual selection under field conditions

description: In polygamous systems, male fitness is determined not only by mating
 success but also by fertilization success. Despite the growing interest
 over the past several decades in postcopulatory sexual selection, its
 relative importance compared to precopulatory sexual selection remains a
 subject of debate. Here, we use extensive behavioral observations of a
 semi-natural population of Hawaiian swordtail crickets, Laupala cerasina,
 and molecular paternity assignment to measure the opportunities for pre-
 and postcopulatory selection. Because postcopulatory selection has the
 potential to operate at multiple stages, we also separately attribute its
 effects to factors specific to mating events versus factors specific to
 males. We find that variance in postcopulatory success is over four times
 as great as variance in precopulatory success, with most of it unexplained
 by male mating order or the number of nuptial gifts given. Surprisingly,
 we also find that male singing effort is under postcopulatory selection,
 suggesting that males who sing more frequently also have more competitive
 ejaculates. Our results are consistent with the hypothesis that high
 polyandry levels promote greater relative postcopulatory selection. They
 also highlight the need for detailed behavioral observations under
 conditions as natural as possible when measuring mating and reproductive
 success.

title: Data from: Phantoms of the forest: legacy risk effects of a regionally extinct large carnivore

description: The increased abundance of large carnivores in Europe is a conservation
 success, but the impact on the behavior and population dynamics of prey
 species is generally unknown. In Europe, the recolonization of large
 carnivores often occurs in areas where humans have greatly modified the
 landscape through forestry or agriculture. Currently, we poorly understand
 the effects of recolonizing large carnivores on extant prey species in
 anthropogenic landscapes. Here, we investigated if ungulate prey species
 showed innate responses to the scent of a regionally exterminated but
 native large carnivore, and whether the responses were affected by
 human-induced habitat openness. We experimentally introduced brown bear
 Ursus arctos scent to artificial feeding sites and used camera traps to
 document the responses of three sympatric ungulate species. In addition to
 controls without scent, reindeer scent Rangifer tarandus was used as a
 noncarnivore, novel control scent. Fallow deer Dama dama strongly avoided
 areas with bear scent. In the presence of bear scent, all ungulate species
 generally used open sites more than closed sites, whereas the opposite was
 observed at sites with reindeer scent or without scent. The opening of
 forest habitat by human practices, such as forestry and agriculture,
 creates a larger gradient in habitat openness than available in relatively
 unaffected closed forest systems, which may create opportunities for prey
 to alter their habitat selection and reduce predation risk in
 human-modified systems that do not exist in more natural forest systems.
 Increased knowledge about antipredator responses in areas subjected to
 anthropogenic change is important because these responses may affect prey
 population dynamics, lower trophic levels, and attitudes toward large
 carnivores. These aspects may be of particular relevance in the light of
 the increasing wildlife populations across much of Europe.

title: Data from: Alate production in an aphid in relation to ant tending and alarm pheromone

description: 1. Winged dispersal is vital for aphids as predation pressure and host
 plant conditions fluctuate. 2. Ant-tended aphids also need to disperse,
 but this may represent a cost for the ants, resulting in an evolutionary
 conflict of interest over aphid dispersal. 3. The combined effects of
 aphid alarm pheromone, indicating predation risk, and ant attendance on
 the production of winged aphids were examined in an experiment with Aphis
 fabae (Homoptera: Aphididae) (Scopoli 1763) aphids and Lasius niger
 (Formicidae: Formicinae) (Linné, 1758) ants. 4. This study is the first to
 investigate the joint effects of alarm pheromone and ant attendance, and
 also the first to detect an influence of alarm pheromone on the production
 of winged morphs in A. fabae. 5. After a period of 2 weeks, it was found
 that aphid colonies exposed to intermittent doses of alarm pheromone
 produced more winged individuals, whereas ant tending had the opposite
 effect. The effects were additive on a log scale, and ant attendance had a
 greater proportional influence than exposure to alarm pheromone. A
 tentative conclusion is that ants have gained the upper hand in an
 evolutionary conflict about aphid dispersal.

title: Data from: Copulation order, density cues and variance in fertilization success in a cestode

description: Simultaneous hermaphrodites maximize their fitness by optimizing their
 investment into male or female functions. Allocation of resources to male
 function (tissues, traits, and/or behaviours increasing paternity) is
 predicted to increase as density, and the associated level of sperm
 competition, increases. We tested whether the simultaneous hermaphroditic
 cestode Schistocephalus solidus uses cues of potential partner densities
 in its fish intermediate host to improve its male reproductive success in
 the final host. We had two worms, one originating from a multiple
 infection in the fish intermediate host and one from a single infection,
 sequentially compete to fertilize the eggs of a third worm. The
 fertilization rates of the two competitors nearly always differed from the
 50-50 null expectation, sometimes considerably, implying there was a
 'winner' in each experimental competition. However, we did not
 find a significant effect of density in the fish host (single vs multiple)
 or mating order on paternity. Additional work will be needed to identify
 the traits and environmental conditions that explain the high variance in
 male reproductive success observed in this experiment.
