title: Data from: Phylogenetic relationships in the southern African genus Drosanthemum (Ruschioideae, Aizoaceae)

description: Background. Drosanthemum, the only genus of the tribe
 Drosanthemeae, is widespread over the Greater Cape Floristic Region in
 southern Africa. With 114
 recognized species, Drosanthemum together with
 the highly succulent and species-rich tribe Ruschieae constitute the ‘core
 ruschioids’ in Aizoaceae. Within Drosanthemum, nine subgenera
 have been described based on flower and fruit morphology. Their
 phylogenetic relationships, however, have not yet been investigated,
 hampering understanding of monophyletic entities and patterns of
 geographic distribution. Methods. Using chloroplast and nuclear DNA
 sequence data, we performed network- and tree-based phylogenetic analyses
 of 73 species of Drosanthemum with multiple accessions
 for widespread species. A well-curated, geo-referenced occurrence data set
 comprising the 134 genetically analysed and 863 further accessions was
 used to describe the distributional ranges of intrageneric lineages and
 the genus as a whole. Results. Phylogenetic inference supports
 nine clades within Drosanthemum, seven of which group in two
 major clades, while the remaining two show ambiguous affinities. The nine
 clades are generally congruent to previously described subgenera
 within Drosanthemum, with exceptions such as (pseudo-) cryptic
 species. In-depth analyses of sequence patterns in each gene region were
 used to reveal phylogenetic affinities inside the retrieved clades in more
 detail. We observe a complex distribution pattern including widespread,
 species-rich clades expanding into arid habitats of the interior
 (subgenera Drosanthemum p.p., Vespertina, Xamera) that
 are genetically and morphologically diverse. In contrast, less
 species-rich, genetically less divergent, and morphologically unique
 lineages are restricted to the central Cape region and more mesic
 conditions (Decidua, Necopina, Ossicula, Quastea, Quadrata,
 Speciosa). Our results suggest that the main lineages arose from an
 initial rapid radiation, with subsequent diversification in some clades.

title: Noninvasive fecal sampling in Itatiaia National Park, Brazil: wild mammal identification and parasite detection

description: Background: Noninvasive collection of feces is a cost-effective strategy
 for monitoring free-living wild mammals. The aim of this study was to
 search for carnivore and artiodactyl species and investigate the
 gastrointestinal parasites in their feces, in Itatiaia National Park,
 Brazil. Methodology/Main Findings: Between 2017 and 2018, feces from
 carnivores and artiodactyls were collected along trails in the park. Host
 species were identified from these feces through macroscopic and
 trichological examination and through molecular biology using
 mitochondrial gene fragments. To investigate parasites, the Faust, Lutz
 and modified Ritchie and Sheather techniques and enzyme immunoassays were
 used to detect Cryptosporidium sp. antigens. A total of 244 stools were
 collected in three regions of the park. The species identified were C.
 brachyurus (39.7%), L. guttulus (21.3%), C. familiaris (5.3%), C. thous
 (0.8%), Puma yagouaroundi (0.8%), L. pardalis (0.4%), P. concolor (0.4%)
 and S. scrofa (4.9%). The overall positivity for parasites was 81.1%.
 Helminths were more frequently detected in carnivore feces (70.9%),
 especially eggs of the family Ascarididae and Toxocara sp. Protozoa
 presented higher frequency in artiodactyl feces (87.1%), especially
 coproantigens of Cryptosporidium sp. This zoonotic protozoon was detected
 in eight mammal species, including one that may be invasive: animals from
 crossbreeding of domestic pig with wild boar. High values for parasite
 structural richness (R’), Shannon (H’) and Simpson (D) parasite diversity
 indices were observed, especially in the feces of C. brachyurus (R’ = 12,
 H' = 2.2761, D = 0.887). Significant differences in parasite
 diversity were observed between C. brachyurus and C. familiaris; and
 between C. brachyurus and S. scrofa (pooled t test = 0.01 and 0.03,
 respectively). The highest values for parasite similarity (Sorensen test ≥
 0.8) were found among species that are taxonomically close, such as C.
 brachyurus and L. guttulus. Conclusions/Significance: This was the first
 parasitological survey on carnivore and artiodactyl feces collected
 noninvasively in Brazil. It enabled animal identification through
 correlations using three techniques and diagnosis of highly frequent
 parasite structures that can infect these animals.

title: Inquiline predator increases nutrient-cycling efficiency of Nepenthes rafflesiana pitchers

description: The modified-leaf pitchers of Nepenthes rafflesiana pitcher plants are
 aquatic, allochthonous ecosystems which are inhabited by specialist
 inquilines and sustained by the input of invertebrate prey. Detritivorous
 inquilines are known to increase the nutrient-cycling efficiency (NCE) of
 pitchers but it is unclear if predatory inquilines which prey on these
 detritivores decrease the NCE of pitchers by reducing detritivore
 populations or increase the NCE of pitchers by processing nutrients that
 may otherwise be locked up in detritivore biomass. Nepenthosyrphus is a
 small and poorly studied genus of hoverflies and the larvae of one such
 species is a facultatively detritivorous predator which inhabits the
 pitchers of N. rafflesiana. We fitted a consumer–resource model to
 experimental data collected from this system. Simulations showed that
 systems containing the predator at equilibrium almost always had higher
 NCEs than those containing only prey (detritivore) species. We showed
 using a combination of simulated predator/prey exclusions that the
 processing of the resource through multiple pathways and trophic levels in
 this system is more efficient than that accomplished through fewer
 pathways and trophic levels. Our results thus support the vertical
 diversity hypothesis which predicts that greater diversity across trophic
 levels results in greater ecosystem functioning.

title: Carotenoid- but not melanin-based plumage coloration is negatively related to metal exposure and proximity to the road in an urban songbird

description: Rapid urbanization is a global phenomenon that is increasingly exposing
 organisms to novel stressors.  These novel stressors can
 affect diverse aspects of organismal function, including development of
 condition-dependent ornaments, which play critical roles in social and
 sexual selection.  We investigated the relationship
 between metal pollution, proximity to roads, and carotenoid- and
 melanin-based plumage coloration in a common songbird, the great tit
 (Parus major).  We studied populations located across a
 well-characterized metal pollution gradient and surrounded by roadway
 networks.  Metal exposure and road-associated pollution
 could reduce carotenoid-based pigmentation by inducing oxidative stress or
 affecting habitat quality, but metals could also enhance melanin-based
 pigmentation, through effects on melanogenesis and testosterone
 concentrations.  Using a large sample size (N
 &gt;500), we found that birds residing close to a point source for
 metals had reduced ultraviolet chroma, a component of carotenoid-based
 pigmentation.  Moreover, birds with high feather metal
 concentrations had lower carotenoid chroma, hue, and ultraviolet chroma,
 with effects modified by age class.  Birds residing
 closer to roads also had lower carotenoid chroma and
 hue.  Melanin-based pigmentation showed high
 between-year repeatability, and no association with anthropogenic
 pollution.  Results suggest that carotenoid-, but not
 melanin-, based pigmentation is negatively affected by multiple
 anthropogenic stressors.  We are the first to
 demonstrate a negative association between roads and a plumage-based
 signaling trait, which could have important implications for sexual
 signaling dynamics in urban landscapes.
description: Blood and feather samples were collected from great tits
 (<em>Parus major</em>) breeding across a well-described metal
 pollution gradient in the vicinity of Antwerp, Belgium.  We measured
 concentrations of five metals (Pb, Cd, Cu, As, Zn) in blood and feather
 samples using a coupled plasma-mass spectrometer (7700× ICP-MS, Agilent
 Technologies, Santa Clara, CA, USA).  We measured carotenoid-based plumage
 coloration from breast feather samples using spectrophotometry.
  Melanin-based coloration was measured by taking digital photographs of
 the breast and analyzing the images in ImageJ.  We also took standard body
 measurements (body mass, tarsus length) from birds.

title: Data from: Increased levels of perceived competition decrease juvenile kin-shoaling preferences in a cichlid fish

description: Inclusive fitness theory predicts that individuals can increase their
 indirect fitness by grouping with kin. However, kin-grouping also
 increases competition between kin, which potentially outweighs its
 benefits. The level of kin-competition is contingent on environmental
 conditions and thus highly variable. Hence, individuals should benefit
 from plastically adjusting kin-discrimination according to the expected
 level of kin competition. Here, we investigate whether perceived high
 competition affects juvenile kin-shoaling preferences in the cichlid
 Pelvicachromis taeniatus. Juveniles were given the choice between two
 shoals consisting of either kin or non-kin. Levels of perceived
 competition were manipulated through food limitation in the face of the
 differential energy expenditure of differently sized fish. The preference
 to shoal with kin decreased with increasing levels of perceived
 competition; small food-deprived individuals avoided kin. Shoaling with
 kin under strong competition may reduce individual indirect fitness.
 Hence, individuals can likely improve their inclusive fitness by
 plastically adjusting their kin-grouping preferences.

title: Dataset for "Space use by animals on the urban fringe: interactive effects of sex and personality"

description: Personality traits shape individual perceptions of risks and rewards, and
 so, should affect how animals value and use their environment. Evidence is
 emerging that personality affects foraging, space use and exploitation of
 novel environments such as urban habitat. But the influence of personality
 is also hypothesized to be sex-dependent when primary motivation for space
 use differs between sexes, as often occurs in polygynous species. We
 tested the influence of personality traits, interacting with sex, on space
 use by the polygynous common brushtail possum, Trichosurus vulpecula, in
 an urban-woodland boundary in Sydney, Australia. We quantified personality
 traits, including exploration, using behavioural assays in an artificial
 arena. We also GPS-tracked free-ranging individuals, and measured range
 size, core area: home range, and proportional urban range. We found that
 personality traits affected space use either as a main effect or, as
 predicted, an interaction with sex. More exploratory animals, regardless
 of sex, had higher core area: home range ratios and proportionally larger
 ranges within urban habitat. However, less exploratory females yet more
 exploratory males had larger ranges. Our findings provide new insight into
 movement ecology by demonstrating, for the first time, the sex-dependent
 influence of personality. The demonstrated influence of personality on
 urban use by possums also suggests a personality filter for wildlife, as
 populations transition into urban areas. Finally, as individuals at the
 interface between urban and natural habitat are also a conduit between the
 two, a corollary of our findings is that there may be personality-mediated
 spread of disease across this boundary.

title: How do red-eyed treefrog embryos sense motion in predator attacks? Assessing the role of vestibular mechanoreception

description: The widespread ability to alter hatching timing in response to
 environmental cues can serve as a defense against threats to eggs.
 Arboreal embryos of red-eyed treefrogs, Agalychnis callidryas, hatch up to
 30% prematurely to escape predation. This escape-hatching response is cued
 by physical disturbance of eggs during attacks, including vibrations or
 motion, and thus depends critically on mechanosensory ability.
 Predator-induced hatching appears later in development than
 flooding-induced, hypoxia-cued hatching; thus, its onset is not
 constrained by the development of hatching ability. It may, instead,
 reflect the development of mechanosensor function. We hypothesize that
 vestibular mechanoreception mediates escape-hatching in snake attacks, and
 that the developmental period when hatching-competent embryos fail to flee
 from snakes reflects a sensory constraint. We assessed the ontogenetic
 congruence of escape-hatching responses and an indicator of vestibular
 function, the vestibulo-ocular reflex (VOR), in three ways. First, we
 measured VOR in two developmental series of embryos 3–7 days old to
 compare with the published ontogeny of escape success in attacks. Second,
 during the period of greatest variation in VOR and escape success, we
 compared hatching responses and VOR across sibships. Finally, in
 developmental series, we compared the response of individual embryos to a
 simulated attack cue with their VOR. The onset of VOR and hatching
 responses were largely concurrent at all three scales. Moreover, latency
 to hatch in simulated attacks decreased with increasing VOR. These results
 are consistent with a key role of the vestibular system in the
 escape-hatching response of A. callidryas embryos to attacks.

title: Microevolutionary change in mimicry? Erosion of rattling behaviour among nonvenomous snakes on islands lacking rattlesnakes

description: Batesian mimics––harmless species that converge on the warning signals of
 a dangerous species––are spectacular examples of adaptation, but few
 documented cases involve acoustic signals. Even fewer studies have
 documented microevolutionary change in mimicry of any kind. Here, we
 describe potential evolutionary change in acoustic mimicry. Many
 nonvenomous snakes vibrate their tail tip when threatened, making a sound
 resembling a venomous rattlesnake. When we compared this behaviour between
 gopher snakes from mainland California where rattlesnakes are present
 versus nearby derived island populations where rattlesnakes are absent, we
 found that island snakes vibrated their tail for a shorter duration. Thus,
 defensive tail vibration may be acoustic mimicry of rattlesnakes that is
 undergoing erosion in an area lacking rattlesnakes, providing evidence of
 possible microevolutionary change in mimicry.

title: Data from: Introduced plants as novel Anthropocene habitats for insects

description: Insect-plant interactions from an extensive field experiment spanning
 several years (2010-2016), which examined the insects sampled
 from 69 garden plant species that vary in their relatedness to the native
 flora of Great Britain. The 69 plant species were organised into
 23 species triplets, with a third of the plots containing a mixture of
 native plant species, a third containing a mixture of non-native species
 closely related to the natives (‘congeners’), and the remaining third of
 the plots containing a mixture of distantly or unrelated ‘exotic’ plant
 species from the southern Hemisphere. Pollinators were identified
 in situ, whereas frozen Vortis suction samples were identified in the
 laboratory. All insect taxa were identified to as close to species level
 as possible. For further information please see Padovani et al.
 (2019).

title: Species delimitation, classical taxonomy, and genome skimming: a review of the ground beetle genus Lionepha (Coleoptera: Carabidae)

description: The western North American genus Lionepha is shown to
 contain at least 11 species through a combination of eight-gene species
 delimitation analyses and morphological study. In order to confirm the
 names of several species, we sequence DNA of primary types of several
 names, including a LeConte lectotype collected in the 1850s, using
 next-generation sequencing. We examine chromosomes of eight species, and
 show that all have 12 pairs of autosomes and an X0/XX sex-chromosome
 system. The following species are described as new: Lionepha
 australerasa, L. kavanaughi, L. lindrothi,
 and L. tuulukwa. The name Lionepha erasa is
 shown to belong to a relatively rare, western species ranging from Oregon
 through Alaska; the common, widespread species previously known
 as Lionepha erasa now takes the name L.
 probata. Bembidion lindrothellus, B. chintimini,
 and B. lummi are synonymized with L.
 erasa. We provide tools to identify specimens to species,
 including illustrations and diagnoses.

title: Flight capacity increases then declines from the core to the margins of an invasive species’ range

description: Individuals that disperse farther than other individuals are more likely
 to be on the frontlines of spreading populations and may be more likely to
 mate with one another as a consequence of their spatial proximity. Over
 generations, this process—known as spatial sorting—can produce patterns of
 increasing dispersal ability from a population’s core towards the
 spreading front. By contrast, when the spread of a population is limited
 by the availability of suitable habitat, theory predicts that range
 boundaries can select against more dispersive phenotypes and produce
 patterns of decreasing dispersal capacity towards population margins. In a
 common garden study of invasive kudzu bugs (Megacopta cribraria)—which are
 limited by the availability of hostplants in their southern and western
 margins—I show that midrange individuals fly 49% farther than individuals
 in the core and 37% farther than individuals at margins. This result
 highlights that other processes, such as maternal effects or selection at
 range boundaries, may create more complicated patterns of dispersal
 ability across landscapes than predicted by models of spatial sorting
 alone.
description: <br> These data are from a common garden study of kudzu bug
 flight performance, as measured on flight mills (see methods). Each row
 describes measurements from a single individual and includes
 characteristics associated with the site from which it was
 collected.  There are two datasets: (1) a complete
 dataset with all flights, including individuals that did not fly, and (2)
 a reduced dataset, which excludes non-flying insects and those that flew
 two rotations or less.
