title: Data from: Herbivore consumers face different challenges along opposite sides of the stoichiometric knife edge

description: Anthropogenic activities have reshaped the relative supply rates of
 essential elements to organisms. Recent studies suggested that consumer
 performance is strongly reduced by food that is either very high or very
 low in relative phosphorus content. However, the generality of such
 ‘stoichiometric knife-edge’ and its underlying mechanisms are poorly
 understood. We studied the response of a planktonic rotifer to a tenfold
 food carbon:phosphorus (C:P) gradient and confirmed the existence of the
 stoichiometric knife-edge. Interestingly, we observed a complete
 homeostatic breakdown associated with strong growth reductions at high
 food C:P. In contrast, at low food C:P animals maintained homeostasis
 despite pronounced performance reductions. Our results suggest that the
 mechanisms underlying adverse effects of stoichiometric imbalance are
 determined by both the identity of elements that are limiting and those
 that are present in excess. Negative effects of excess P reveal an
 additional way of how eutrophication may negatively affect consumers.

title: Data from: Alien species spreading via biofouling on recreational vessels in the Mediterranean Sea

description: 1. Despite the Mediterranean being both a hotspot for recreational boating
 and for non-indigenous species (NIS), no data currently exists on the
 recreational boating sector’s contribution to the spread of NIS in this
 Sea. 2. To improve the basis for management decisions, a wide-scale
 sampling study on the biofouling communities of recreational vessels and
 marinas was undertaken. Specifically, we surveyed over 600 boat owners and
 sampled the same boat hulls for NIS in 25 marinas across the
 Mediterranean, from France to Cyprus, to determine which factors (i.e.,
 boat characteristics, travel behaviour, home marina) are associated with
 higher NIS richness on boat-hulls. 3. Among the surveyed boats, we found
 recreational vessels to travel considerably, averaging 67 travel days and
 7.5 visited marinas per annum. This results in a high potential for
 spreading NIS, especially as 71% of sampled vessels host at least one (and
 up to 11) NIS. Boats with high NIS richness strongly correlate with home
 marinas with high NIS richness. Over half of the vessels were carriers of
 NIS which were not yet present in the marinas they were visiting. The
 presence of biofouling in niche areas of the hull (i.e., in the cavities
 and metallic parts) emerges as the best predictor for NIS richness on
 boats, along with longer elapsed times since their last cleaning and
 antifouling applications. Interestingly, colonization of NIS occurred
 rapidly, even on boats that had recently had their hulls cleaned
 professionally. Synthesis and applications. We demonstrate that
 recreational boating has a very high capacity for the spread of
 non-indigenous species (NIS) in the Mediterranean, due to both high NIS
 richness on boats and extensive regional and extra-regional travel. To
 counteract the spread of NIS, routine monitoring for new NIS needs to be
 established for both marinas and vessels, along with frequent pontoon
 cleaning. Additionally, management and policy actions should demand
 preliminary screenings for incoming vessels from new countries, especially
 those emanating from high-risk marinas. In these screenings, particular
 attention should be paid to biofouling presence in the niche areas of the
 boat hulls, which was the best predictor for NIS richness since the niche
 areas seldom have antifouling coatings applied to them and often go missed
 with in-water cleanings.

title: Data from: Experimental evidence that intruder and group member attributes affect outgroup defence and associated within-group interactions in a social fish

description: In many social species, individuals communally defend resources from
 conspecific outsiders. Participation in defence and in associated
 within-group interactions, both during and after contests with outgroup
 rivals, is expected to vary between group members because the threat
 presented by different outsiders is not the same to each individual.
 However, experimental tests examining both the contributions to, and the
 consequences of, outgroup conflict for all group members are lacking.
 Using groups of the cichlid Neolamprologus pulcher, we simulated
 territorial intrusions by different-sized female rivals and altered the
 potential contribution of subordinate females to defence. Dominant and
 subordinate females defended significantly more against size- and
 rank-matched intruders, while males displayed lower and less variable
 levels of defence. Large and small, but not intermediate-sized, intruders
 induced increased levels of within-group aggression during intrusions,
 which was targeted at the subordinate females. Preventing subordinate
 females from helping in territorial defence led to significant decreases
 in post-contest within-group and female-specific submissive and
 affiliative displays. Together, these results show that the defensive
 contributions of group members vary greatly depending both on their own
 traits and on intruder identity, and this variation has significant
 consequences for within-group social dynamics both during and in the
 aftermath of outgroup contests.

title: Data from: Neurophysiological evidence for crossmodal person-identity representation in the human left ventral temporal cortex

description: Putting a name to a face is a highly common activity in our daily life
 that greatly enriches social interactions. Although this specific
 person-identity association becomes automatic with learning, it remains
 difficult and can easily be disrupted in normal circumstances or
 neurological conditions. To shed light on the neural basis of this
 important and yet poorly understood association between different input
 modalities in the human brain, we designed a crossmodal frequency-tagging
 paradigm coupled to brain activity recording via scalp and intracerebral
 electroencephalography. In Experiment 1, 12 participants were presented
 with variable pictures of faces and written names of a single famous
 identity at a 4 Hz frequency rate while performing an orthogonal task.
 Every 7 items, another famous identity appeared, either as a face or a
 name. Robust electrophysiological responses were found exactly at the
 frequency of identity change (i.e., 4 Hz / 7 = 0.571 Hz), suggesting a
 crossmodal neural response to person identity. In Experiment 2 with twenty
 participants , two control conditions with periodic changes of identity
 for faces or names only were added to estimate the contribution of
 unimodal neural activity to the putative crossmodal face-name responses.
 About 30% of the response occurring at the frequency of crossmodal
 identity change over the left occipito-temporal cortex could not be
 accounted for by the linear sum of unimodal responses. Finally,
 intracerebral recordings in the left ventral anterior temporal lobe in 7
 epileptic patients tested with this paradigm revealed a small number of
 ‘pure’ crossmodal responses, i.e. with no response to changes of identity
 for faces or names only. Altogether, these observations provide evidence
 for integration of verbal and non-verbal person identity-specific
 information in the human brain, highlighting the contribution of the left
 ventral ATL in the automatic retrieval of face-name identity associations.

title: A new approach to map landscape variation in forest restoration success in tropical and temperate forest biomes

description: A high level of variation of biodiversity recovery within a landscape
 during forest restoration presents obstacles to ensure large‐scale,
 cost‐effective and long‐lasting ecological restoration. There is an urgent
 need to predict landscape variation in forest restoration success at a
 global scale. We conducted a meta‐analysis comprising 135 study landscapes
 to predict and map landscape variation in forest restoration success in
 tropical and temperate forest biomes. Our analysis was based on the amount
 of forest cover within a landscape — a key driver of forest restoration
 success. We contrasted 17 generalized linear models measuring forest cover
 at different landscape sizes (with buffers varying from 5 to
 200 km radii). We identified the most plausible model to predict
 and map landscape variation in forest restoration success. We then
 weighted landscape variation by the amount of potentially restorable areas
 (agriculture and pasture land areas) within the same landscape. Finally,
 we estimated restoration costs of implementing Bonn Challenge commitments
 in three specific temperate and tropical forest biome types in the United
 States, Brazil and Uganda. Landscape variation decreased exponentially as
 the amount of forest cover increased in the landscape, with stronger
 effects within a 5 km radius. Thirty‐eight per cent of forest
 biomes have landscapes with more than 27% of forest cover and showed
 levels of landscape variation below 10%. Landscapes with less than 6% of
 forest cover showed levels of variation in forest restoration success
 above 50%. At the biome level, Tropical and Subtropical Moist Broadleaf
 Forests had the lowest (12.6%), whereas Tropical and Subtropical Dry
 Broadleaf Forests had the highest (22.9%) average of weighted landscape
 variation in forest restoration success. Our approach can lead to a
 reduction in implementation costs for each Bonn Challenge commitment
 between US$ 973 Mi and 9.9 Bi. Policy implications. Our approach
 identifies landscape characteristics that increase the likelihood of
 biodiversity recovery during forest restoration — and potentially the
 chances of natural regeneration and long‐term ecological sustainability
 and functionality. Identifying areas with low levels of landscape
 variation can help to reduce the risks and financial costs associated with
 implementing ambitious restoration commitments.

title: Data from: Tandem host-parasite dispersal inferred from similarities in phylogeographic patterns among little penguins and their ‘terrestrial’ ectoparasites

description: Aim Organisms with poor intrinsic dispersal capacity, such as parasites,
 often rely entirely on transport with host species that have a greater
 dispersal capacity. Penguins, for example, are exploited by terrestrial
 ectoparasites when they come ashore to breed. Recent research indicates
 that little penguin (Eudyptula minor and E. novaehollandiae) hard ticks
 (Ixodes eudyptidis and I. kohlsi) may be capable of surviving short
 periods (days) at sea with their hosts, but their capacity to survive
 longer voyages (weeks) is not known. We here aimed to assess whether
 phylogeographic patterns in little penguins and their ticks indicate that
 the terrestrial ectoparasites are able to disperse long distances at sea
 with their swimming hosts. Location Southern Australia and New Zealand.
 Taxon Ixodes eudyptidis and I. kohlsi ticks. Methods We conducted a
 broad-scale genomic assessment of little penguin ticks from across their
 hosts’ ranges in Australia and New Zealand. Using Genotyping by Sequencing
 (GBS), we generated SNP data sets from ticks from 14 penguin colonies, and
 analysed phylogeographic structure. We included ticks from some sympatric
 flighted seabirds to verify host-specificity. Results We resolved two
 distinct lineages of Ixodes from little penguins, with one restricted to
 Australia, and the other found throughout New Zealand and in low numbers
 at some eastern Australian sites. Both lineages exhibited phylogeographic
 structure consistent with patterns observed in their hosts, with some
 evidence of occasional oceanic dispersal, including across the Tasman Sea
 between Australia and New Zealand. Ticks from sympatric short-tailed
 shearwaters (Ardenna tenuirostris), which disperse aerially, were
 genetically distinct from those collected from little penguins, supporting
 prior evidence of host-specificity in seabird ticks. Main conclusions The
 most parsimonious explanation for our results is that ticks can travel at
 sea with little penguins. We infer that some terrestrial ectoparasites
 associated with aquatically-dispersing hosts have evolved the capacity to
 survive oceanic voyages.

title: Context dependency of top‐down, bottom‐up and density‐dependent influences on cheetah demography

description: 1. Research on drivers of demographic rates has mostly focused on top
 predators and their prey, and comparatively less research has considered
 the drivers of mesopredator demography. Of those limited studies, most
 focused on top-down effects of apex predators on mesopredator population
 dynamics, whereas studies investigating alternative mechanisms are less
 common. 2. In this study, we tested hypotheses related to top-down,
 bottom-up, and density-dependent regulation of demographic rates in an
 imperiled mesopredator, the cheetah (Acinonyx jubatus). 3. We used a
 25-year dataset of lion density, cheetah density, and prey density from
 the Mun-Ya-Wana Conservancy in South Africa and assessed the effects of
 top-down, bottom-up, and density-dependent drivers on cheetah survival and
 reproduction. 4. In contrast to the top-down and bottom-up predications,
 both adult and juvenile cheetahs experienced the lowest survival during
 months with high prey densities and low lion densities. We only observed
 support for a density-dependent response in juvenile cheetahs, where they
 had a higher probability of reaching independence during times with low
 cheetah density, and low prey density. We did not identify any strong
 drivers of litter size. 5. Collectively, our results indicate that high
 apex predator abundance might not always have negative effects on
 mesopredator populations, and suggest that context dependency in top-down,
 bottom-up, and density-dependent factors may regulate demographic rates of
 cheetahs and other mesopredators. Our results highlight the complexities
 of population-level drivers of cheetah demographic rates and the
 importance of considering multiple hypotheses of mesopredator population
 regulation.

title: Data from: Resource acquisition strategies facilitate Gilbertiodendron dewevrei monodominance in African lowland forests

description: 1. Tropical forests are hyperdiverse, yet extensive areas of monodominant
 forest occur in the tropics worldwide. Most long-lived and persistent
 monodominant tree species form ectomycorrhizal fungi symbioses, allowing
 them to obtain nutrients directly from soil organic matter. This might
 promote monodominance by reducing nutrient availability to co-occurring
 species, the majority of which form associations with arbuscular
 mycorrhizal fungi. 2. Gilbertiodendron dewevrei forest is the most
 widespread monodominant forest in tropical Africa. Its distribution
 appears determined in part by moisture availability, but its monodominance
 is not thought to be driven by its fungal partner or soil fertility. 3.
 Here we compare soil fertility of twenty G. dewevrei stands to mixed
 forest from three sites across an 8,400 km2 region of the Central African
 Republic and the Republic of Congo. In contrast to previous studies, we
 find monodominant G. dewevrei stands associated with infertile soils, as
 base cations (calcium, magnesium, total exchangeable bases) and
 extractable manganese are extremely low, and significantly lower in soils
 under G. dewevrei forest compared to mixed forest. Further, and consistent
 with ectomycorrhizal forests globally, soil carbon to nitrogen and carbon
 to phosphorus ratios are significantly higher in G. dewevrei stands than
 in mixed forest stands, providing evidence in support of direct
 acquisition of nitrogen and phosphorus from soil organic matter by
 ectomycorrhizal fungi. 4. Gilbertiodendron dewevrei recruits from the
 seedling bank, with its large seedlings surviving in high densities for
 over a decade. We tested whether light plasticity could facilitate
 monodominance by growing seedlings of G. dewevrei under controlled light
 conditions. We found that its seedlings grow well under a wide range of
 irradiance levels and conclude that this plasticity affords a competitive
 advantage. 5. Synthesis: We reframe the discussion of factors contributing
 to monodominance of G. dewevrei into one of resource acquisition and use
 efficiency. In particular, G. dewevrei is associated with moist and
 infertile soils and competes well under a variety of light conditions. Our
 data is consistent with a model where root associations with
 ectomycorrhizal fungi drive monodominance through the direct acquisition
 of nutrients from soil organic matter, promoting nutrient limitation of
 co-occurring species.

title: Data from: Taxonomic delimitation of species complexes: a challenge for conservation, first steps with Abarema cochliacarpos complex

description: Taxonomic and ecological knowledge of plant species complexes informs
 their conservation status. Poorly delimited species boundaries can lead to
 incorrect assessments of biodiversity, and a rare species might have its
 distribution range overestimated if considering other closely related taxa
 as the same one. The present study investigates the level of morphometric
 variation within the Abarema cochliacarpos complex, throughout its entire
 distribution range in Brazilian Atlantic Forest and Caatinga vegetation,
 and considers the drivers of this variation. A morphometric study using
 cluster, PERMANOVA, and NMDS analyses was conducted. We analyzed patterns
 of trait variation among and within populations, and their relationship
 with environmental factors along with their geographical gradient. From
 the four morphotypes previous cited for the complex, the analyses
 delimited three morphological groups. Their morphological characteristics
 differed in response to environmental drivers. We identified morphological
 characters that differentiated the groups within the complex. The
 development of conservation strategies and actions to fully protect a
 species complex requires the understanding of the morphological variation
 within the complex. In the Abarema cochliacarpos complex different threats
 and challenges are associated with the conservation of each morphotype. We
 highlight the importance of conserving the various morphotypes of a
 species complex which has a large distribution range as evolutionary
 significant units, something that is frequently neglected in the published
 literature.

title: Data from: Geophytism in monocots leads to higher rates of diversification

description: ● Geophytes, plants with buds on underground structures, are found
 throughout the plant tree of life. These below ground structures allow
 plants to inhabit highly seasonal and disturbance-prone environments
 across ecosystems. Past researchers have hypothesized the bulbous, cormous
 and tuberous habits promote diversification, but this had yet to be
 tested. ● Using a comprehensive monocot data set of almost 13,000 taxa, we
 investigated the effects of the geophytic habit on diversification using
 both state-dependent and state-independent models. ● We found that
 geophytes exhibit increased rates of diversification relative to
 non-geophytes. State-dependent analyses recovered higher yet similar rates
 of diversification for bulbous, cormous and tuberous taxa compared to
 rhizomatous and non-geophytic taxa. However, the state-independent model
 returned no difference in rates among the different traits. ● Geophytism
 shows higher rates of diversification relative to non-geophytes but we
 find little support for the hypothesis that the evolution of the bulb,
 corm or tuber appears to provide a diversification increase relative to
 rhizomatous and non-geophytic taxa. Our broad scale analysis highlights
 the overall evolutionary importance of the geophytic habit (i.e.,
 belowground bud placement). However, our results also suggest that
 belowground morphological diversity alone cannot explain this rate
 increase. In order to further test the evolutionary significance of these
 underground structures, future studies should consider them in combination
 with other biotic and abiotic factors.
