title: Data from: Herbivory enhances the resistance of mangrove forest to cordgrass invasion

description: The biotic resistance hypothesis proposes that biotic interactions, such
 as competition and herbivory, resist the establishment and spread of
 non-native species. The relative and interactive role of competition and
 herbivory in resisting plant invasions, however, remains poorly
 understood. We investigated the interactive role of competition and
 herbivory (by the native rodent Rattus losea) in resisting Spartina
 alterniflora (cordgrass) invasions into mangrove forests. In southern
 China, although exotic cordgrass numerically dominates intertidal mudflats
 and open gaps in mangrove forests, intact forests appear to be highly
 resistant to cordgrass invasion. A field transplant and rodent exclusion
 experiment showed that while the impact of rodent grazing on cordgrass was
 weak on mangrove forest edges and open mudflats, rodent grazing strongly
 suppressed cordgrass in mangrove understory habitats. A greenhouse
 experiment confirmed a synergistic interaction between grazing and light
 availability (a proxy for mangrove shading/competition) in suppressing
 cordgrass establishment, with the strongest impacts of grazing in low
 light conditions that likely weakened cordgrass to survive and resprout.
 When both were present, as in mangrove understory habitats, grazing and
 low light acted in concert to eliminate cordgrass establishment, resulting
 in resistance of mangrove forests to cordgrass invasion. Our results
 reveal that grazing by native herbivores can enhance the resistance of
 mangrove forests to cordgrass invasion in southern China, and suggest that
 investigating multifactor interactions may be critical to understanding
 community resistance to exotic invasions.

title: Data from: Variable responses to novel hosts by populations of the seed beetle Callosobruchus maculatus (Coleoptera: Chrysomelidae: Bruchinae)

description: Cosmopolitan pests can consist of geographic populations that differ in
 their current host ranges or in their ability to colonize a novel host. We
 compared the responses of cowpea-adapted seed-beetle populations
 (Callosobruchus maculatus [F.]) from Africa, North America, and South
 America to four novel legumes: chickpea, lentil, mung bean, and pea. We
 also qualitatively compared these results to those obtained earlier for an
 Asian population. For each host, we measured larval survival to adult
 emergence, and used both no-choice and choice tests to estimate host
 acceptance. The pattern of larval survival was similar among populations:
 high or moderately high survival on cowpea, mung bean, and chickpea,
 intermediate survival on pea, and very low survival on lentil. One
 exception was unusually high survival of African larvae on pea, and there
 was modest variation among populations for survival on lentil. The African
 population was also an outlier with respect to host acceptance; under
 no-choice conditions, African females showed a much greater propensity to
 accept the two least preferred hosts, chickpea and lentil. However,
 greater acceptance of these hosts by African females was not evident in
 choice tests. Inferences about populations differences in host acceptance
 can thus strongly depend on experimental protocol. Future selection
 experiments can be used to determine whether the observed population
 differences in initial performance will affect the probability of
 producing self-sustaining populations on a marginal crop host.

title: Data from: Effects of prey density, temperature and predator diversity on nonconsumptive predator-driven mortality in a freshwater food web

description: Nonconsumptive predator-driven mortality (NCM), defined as prey mortality
 due to predation that does not result in prey consumption, is an
 underestimated component of predator-prey interactions with possible
 implications for population dynamics and ecosystem functioning. However,
 the biotic and abiotic factors influencing this mortality component remain
 largely unexplored, leaving a gap in our understanding of the impacts of
 environmental change on ecological communities. We investigated the
 effects of temperature, prey density, and predator diversity and density
 on NCM in an aquatic food web module composed of dragonfly larvae (Aeshna
 cyanea) and marbled crayfish (Procambarus fallax f. virginalis) preying on
 common carp (Cyprinus carpio) fry. We found that NCM increased with prey
 density and depended on the functional diversity and density of the
 predator community. Warming significantly reduced NCM only in the
 dragonfly larvae but the magnitude depended on dragonfly larvae density.
 Our results indicate that energy transfer across trophic levels is more
 efficient due to lower NCM in functionally diverse predator communities,
 at lower resource densities and at higher temperatures. This suggests that
 environmental changes such as climate warming and reduced resource
 availability could increase the efficiency of energy transfer in food webs
 only if functionally diverse predator communities are conserved.

title: Data from: Can Daphnia lumholtzi invade European lakes?

description: The cladoceran Daphnia lumholtzi is a subtropical and tropical
 zooplankter, and an invasive species in North America. Thus far, D.
 lumholtzi has not been detected in Europe. Here we investigated whether a
 hypothetical introduction to Europe could result in a successful invasion,
 either now or in the near future when facilitated by climate change. In
 laboratory experiments, we tested whether different clones of D. lumholtzi
 can invade a resident community consisting of native Daphnia from lake
 Klostersee, Germany, and how invasion success depends on temperature and
 the presence or absence of planktivorous fish. In some treatments,
 invasion success was consistently high, and D. lumholtzi reached densities
 similar to the native competitors by the end of the experiment.
 Surprisingly, the presence of a planktivorous fish inhibited the invasion
 of D. lumholtzi, and a clone with an inducible defense against fish
 predation was a more successful invader than a permanently defended clone.
 Of the three temperatures tested in this study (15, 20, and 24°C),
 invasion success was highest at 20°C. To understand the competitive
 interaction between native and introduced Daphnia, we fit a
 Lotka-Volterra-type competition model to the population dynamics. Our
 experimental and modeling results suggest that D. lumholtzi can invade
 European lakes and can cause substantial declines in the population size
 of native Daphnia, with potential consequences for higher trophic levels.

title: Data from: Quantification of correlational selection on thermal physiology, thermoregulatory behavior and energy metabolism in lizards

description: Phenotypic selection is widely accepted as the primary cause of adaptive
 evolution in natural populations, but selection on complex functional
 properties linking physiology, behavior, and morphology has been rarely
 quantified. In ectotherms, correlational selection on thermal physiology,
 thermoregulatory behavior, and energy metabolism is of special interest
 because of their potential coadaptation. We quantified phenotypic
 selection on thermal sensitivity of locomotor performance (sprint speed),
 thermal preferences, and resting metabolic rate in captive populations of
 an ectothermic vertebrate, the common lizard, Zootoca vivipara. No
 correlational selection between thermal sensitivity of performance,
 thermoregulatory behavior, and energy metabolism was found. A combination
 of high body mass and resting metabolic rate was positively correlated
 with survival and negatively correlated with fecundity. Thus, different
 mechanisms underlie selection on metabolism in lizards with small body
 mass than in lizards with high body mass. In addition, lizards that
 selected the near average preferred body temperature grew faster that
 their congeners. This is one of the few studies that quantifies
 significant correlational selection on a proxy of energy expenditure and
 stabilizing selection on thermoregulatory behavior.

title: Data from: A new moth-preying alpine pitviper species from Qinghai-Tibetan plateau (Viperidae, Crotalinae)

description: The Sanjiangyuan region of Qinghai-Tibetan Plateau is recognized as a
 biodiversity hotspot of alpine mammals but a barren area in terms of
 amphibians and reptiles. Here, we describe a new pit viper species,
 Gloydius rubromaculatus sp. n. Shi, Li and Liu, 2017 that was discovered
 in this region, with a brief taxonomic revision of the genus Gloydius. The
 new species can be distinguished from the other congeneric species by the
 following characteristics: cardinal crossbands on the back, indistinct
 canthus rostralis, glossy dorsal scales, colubrid-like oval head shape,
 irregular small black spots on the head scales, black eyes and high
 altitude distribution (3300-4770 m above sea level). The mitochondrial
 phylogenetic reconstruction supported the validity of the new species and
 furthermore reaffirms that G. intermedius changdaoensis, G. halys
 cognatus, G. h. caraganus and G. h. stejnegeri should be elevated as full
 species. Gloydius rubromaculatus sp. n. was found to be insectivorous:
 preying on moths (Lepidoptera, Noctuidae, Sideridis sp.) in the wild. This
 unusual diet may be one of the key factors to the survival of this species
 in such a harsh alpine environment.

title: Data from: The Lilliput effect in crinoids at the end of the Oceanic Anoxic Event 2: a case study from Poland

description: The Cretaceous period (145-66 Ma) consists of several Oceanic Anoxic
 Events (120-80 Ma), stimulated by global greenhouse effects. The Oceanic
 Anoxic Event 2 (OAE2) occurred worldwide from the late Cenomanian to the
 early-middle Turonian, causing a significant faunal turn-over, mostly in
 marine biota pushing some species to the brink of extinction. Some
 organisms also underwent morphological changes, including reduction in
 size. This anoxic event drove other changes, e.g., habitats or strategy of
 life. Here, we show that stalkless crinoids (comatulids) from the Turonian
 of Poland adapted to unfavorable environmental conditions by reducing
 their body size. Furthermore, at the moment when environmental factors
 become favorable again, these crinoids regained their regular (pre-event)
 size. This phenomenon most probably illustrates the so-called “dwarfing”
 mode of the Lilliput Effect.

title: Data from: Age-related mortality explains life history strategies of tropical and temperate songbirds

description: Life history theory attempts to explain why species differ in offspring
 number and quality, growth rate, and parental effort. I show that
 unappreciated interactions of these traits in response to age-related
 mortality risk challenge traditional perspectives and explain life history
 evolution in songbirds. Counter to a long-standing paradigm, tropical
 songbirds grow at similar overall rates to temperate species but grow
 wings relatively faster. These growth tactics are favored by predation
 risk, both in and after leaving the nest, and are facilitated by greater
 provisioning of individual offspring by parents. Increased provisioning of
 individual offspring depends on partitioning effort among fewer young
 because of constraints on effort from adult and nest mortality. These
 growth and provisioning responses to mortality risk finally explain the
 conundrum of small clutch sizes of tropical birds.

title: Data from: Adult experts’ perceptions of telemental health for youth: a Delphi study

description: Objectives: Our objectives were to measure experts’ opinions and develop
 consensus via the Delphi process on the barriers, applications, and
 concerns associated with telemental health (TMH) for youth. Materials and
 methods: We delivered 3 online surveys over 2 months in Summer, 2016–2025
 adult experts, including adults who experienced youth depression or
 suicidality, parents of youth with lived experience, and professionals (ie
 youth mental health researchers, clinicians/staff, or educators). We used
 the Delphi method to construct Likert and open-ended questions, developing
 expert consensus over 3 iterative surveys on the barriers and benefits of
 TMH for youth. Results: Adult experts identified stigma and knowledge
 barriers to youth mental health care. Although TMH is perceived as
 beneficial for screening, education, follow-up, and emotional support, no
 single delivery method (eg websites or instant messaging) was deemed
 universally beneficial. Discussion: Adults are the developers,
 administrators, and gatekeepers of youth mental health care. Although
 adult experts see potential for TMH to supplement traditional therapy via
 familiar technologies, there is no consensus on the technologies by which
 TMH should be delivered. However, there is consensus that family members
 and friends provide potential pathways to care; thus, an online TMH
 toolkit for youth would be beneficial for both caretakers and
 practitioners. Conclusion: Telemental health may not overcome barriers for
 crisis management but adult experts agreed that TMH had potential benefits
 for youth. Health care organizations should conduct research and provide
 training and education to youth caretakers and practitioners on potential
 barriers and benefits of TMH technologies for youth.

title: Data from: Pathogeography: leveraging the biogeography of human infectious diseases for global health management

description: Biogeography is an implicit and fundamental component of almost every
 dimension of modern biology, from natural selection and speciation to
 invasive species and biodiversity management. However, biogeography has
 rarely been integrated into human or veterinary medicine nor routinely
 leveraged for global health management. Here we review the theory and
 application of biogeography to the research and management of human
 infectious diseases, an integration we refer to as ‘pathogeography’.
 Pathogeography represents a promising framework for understanding and
 decomposing the spatial distributions, diversity patterns and emergence
 risks of human infectious diseases into interpretable components of
 dynamic socio-ecological systems. Analytical tools from biogeography are
 already helping to improve our understanding of individual infectious
 disease distributions and the processes that shape them in space and time.
 At higher levels of organization, biogeographical studies of diseases are
 rarer but increasing, improving our ability to describe and explain
 patterns that emerge at the level of disease communities (e.g.,
 co-occurrence, diversity patterns, biogeographic regionalisation). Even in
 a highly globalized world most human infectious diseases remain
 constrained in their geographic distributions by ecological barriers to
 the dispersal or establishment of their causal pathogens, reservoir hosts
 and/or vectors. These same processes underpin the spatial arrangement of
 other taxa, such as mammalian biodiversity, providing a strong empirical
 ‘prior’ with which to assess the potential distributions of infectious
 diseases when data on their occurrence is unavailable or limited. In the
 absence of quality data, generalized biogeographic patterns could provide
 the earliest (and in some cases the only) insights into the potential
 distributions of many poorly known or emerging, or as-yet-unknown,
 infectious disease risks. Encouraging more community ecologists and
 biogeographers to collaborate with health professionals (and vice versa)
 has the potential to improve our understanding of infectious disease
 systems and identify novel management strategies to improve local, global
 and planetary health.

title: Data from: Experimentally simulating warmer and wetter climate additively improves rangeland quality on the Tibetan Plateau

description: 1. The vast expanses of rangeland on the Tibetan Plateau, which support
 the livelihood of ~9.8 million local inhabitants, have experienced rapid
 climate warming over the past 50 years. At the same time, precipitation
 has increased in large parts of the Plateau but decreased in other parts,
 particularly in the northwest. These trends are predicted to continue into
 the future. However, their potential effects on rangeland quality remain
 unclear. 2. We conducted a two-factor field experiment in which we
 manipulated temperature (control or warming by 1.5–1.8 °C) and
 precipitation (control or 50% reduction or increase in rainfall) in an
 alpine grassland on the north-eastern Tibetan Plateau, starting in 2011.
 From 2014–2016, we measured forage production and community composition,
 and in 2015 forage quality (crude protein, cell soluble contents,
 hemicellulose, cellulose, lignin and digestibility) represented by seven
 abundant species. 3. Overall, warming did not change total forage
 production at plant community level, but increased legume production and
 decreased non-legume forb production. Increased and reduced precipitation
 enhanced and decreased forage production by 18.2% and 12.9%, respectively.
 Increased precipitation in particular increased grass and sedge
 production, but not legume production. 4. Forage quality showed
 species-specific responses to the simulated climate changes. At community
 level, warming and reduced precipitation improved forage quality, which
 was mainly caused by a shift in community composition towards more
 legumes, rather than the direct effects of simulated climate changes.
 Meanwhile, increased precipitation did not reduce forage quality, despite
 the precipitation-induced increase in forage production. 5. Integrating
 forage production and quality into nutrient production as a measure of
 rangeland quality, we found that warming and increased precipitation
 additively improved rangeland quality, while reduced precipitation
 decreased it. 6. Synthesis and applications. Rangeland quality, an
 important ecosystem provisioning service, will benefit from a warmer
 climate on the Tibetan Plateau in the regions with a predicted increase in
 precipitation, but not in those regions where precipitation might be
 reduced in the future. We suggest management strategies, including
 reseeding native legumes, establishing sustainable pastures and assisting
 the exchange of harvested forage, to cope with the challenges posed by
 these different climate change scenarios.

title: Data from: Deleterious consequences of antioxidant supplementation on lifespan in a wild-derived mammal

description: While oxidative damage due to reactive oxygen species (ROS) often
 increases with advancing age and is associated with many age-related
 diseases, its causative role in ageing is controversial. In particular,
 studies that have attempted to modulate ROS-induced damage, either upwards
 or downward, using antioxidant or genetic approaches, generally do not
 show a predictable effect on lifespan. Here we investigated whether
 dietary supplementation with either vitamin E (α-tocopherol) or vitamin C
 (ascorbic acid) affected oxidative damage and lifespan in short-tailed
 field voles, Microtus agrestis. We predicted that antioxidant
 supplementation would reduce ROS-induced oxidative damage and increase
 lifespan relative to unsupplemented controls. Antioxidant supplementation
 for 9 months reduced hepatic lipid peroxidation, but DNA oxidative damage
 to hepatocytes and lymphocytes was unaffected. Surprisingly, antioxidant
 supplementation significantly shortened lifespan in voles maintained under
 both cold (7±2°C) and warm (22±2°C) conditions. These data further
 question the predictions of free radical theory of ageing and critically,
 given our previous research in mice, indicate that similar levels of
 antioxidants can induce widely different inter-specific effects on
 lifespan.
