A bibliometric analysis of battery research with the BATTERY 2030+ roadmap as point of departure
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In this bibliometric study, we analyze the six battery research subfields identified in the BATTERY 2030+ roadmap: Battery Interface Genome, Materials Acceleration Platform, Recyclability, Smart functionalities: Self-healing, Smart functionalities: Sensing, and Manufacturability. In addition, we analyze the entire research field related to BATTERY 2030+ as a whole, using two operationalizations. We (a) evaluate the European standing in the subfields/the BATTERY 2030+ field in comparison to the rest of the world, and (b) identify strongholds of the subfields/the BATTERY 2030+ field across Europe. For each subfield and the field as a whole, we used seed articles, i.e. articles listed in the BATTERY 2030+ roadmap or cited by such articles, in order to generate additional, similar articles located in an algorithmically obtained classification system. The output of the analysis is publication volumes, field normalized citation impact values with comparisons between country/country aggregates and between organizations, co-publishing networks between countries and organizations, and keyword co-occurrence networks. For the results related to (a), the performance of EU & associated (countries) is similar to China and the aggregate Japan-South Korea-Singapore and well below North America regarding citation impact and with respect to the field as a whole. Exceptions are, however, the subfields Battery Interface Genome and Recyclability. For the results related to (b), there is a large variability in the EU & associated organizations regarding volume in the different subfields. For citation impact, examples of high-performing EU & associated organizations are ETH Zurich and Max Planck Society for the Advancement of Science.

The link between ethnic diversity and scientific impact : the mediating effect of novelty and audience diversity

Tidskriftsartikel (refereegranskat)abstract
- Understanding the nature and value of scientific collaboration is essential for sound management and proactive research policies. One component of collaboration is the composition and diversity of contributing authors. This study explores how ethnic diversity in scientific collaboration affects scientific impact, by presenting a conceptual model to connect ethnic diversity, based on author names, with scientific impact, assuming novelty and audience diversity as mediators. The model also controls for affiliated country diversity and affiliated country size. Using path modeling, we apply the model to the Web of Science subject categories Nanoscience & Nanotechnology, Ecology and Information Science & Library. For all three subject categories, and regardless of if control variables are considered or not, we find a weak positive relationship between ethnic diversity and scientific impact. The relationship is weaker, however, when control variables are included. For all three fields, the mediated effect through audience diversity is substantially stronger than the mediated effect through novelty in the relationship, and the former effect is much stronger than the direct effect between the ethnic diversity and scientific impact. Our findings further suggest that ethnic diversity is more associated with short-term scientific impact compared to long-term scientific impact.

MTH1 inhibition eradicates cancer by preventing sanitation of the dNTP pool
- 2014

Tidskriftsartikel (refereegranskat)abstract
- Cancers have dysfunctional redox regulation resulting in reactive oxygen species production, damaging both DNA and free dNTPs. The MTH1 protein sanitizes oxidized dNTP pools to prevent incorporation of damaged bases during DNA replication. Although MTH1 is non-essential in normal cells, we show that cancer cells require MTH1 activity to avoid incorporation of oxidized dNTPs, resulting in DNA damage and cell death. We validate MTH1 as an anticancer target in vivo and describe small molecules TH287 and TH588 as first-in-class nudix hydrolase family inhibitors that potently and selectively engage and inhibit the MTH1 protein in cells. Protein co-crystal structures demonstrate that the inhibitors bindin the active site of MTH1. The inhibitors cause incorporation of oxidized dNTPs in cancer cells, leading to DNA damage, cytotoxicity and therapeutic responses in patient-derived mouse xenografts. This study exemplifies the non-oncogene addiction concept for anticancer treatment and validates MTH1 as being cancer phenotypic lethal.

Can Life History Predict the Effect of Demographic Stochasticity on Extinction Risk?
- 2012
-
Ingår i: American Naturalist. - : University of Chicago Press. - 0003-0147 .- 1537-5323. ; 179, s. 706-720
-
Tidskriftsartikel (refereegranskat)abstract
- Demographic stochasticity is important in determining extinction risks of small populations, but it is largely unknown how its effect depends on the life histories of species. We modeled effects of demographic stochasticity on extinction risk in a broad range of generalized life histories, using matrix models and branching processes. Extinction risks of life histories varied greatly in their sensitivity to demographic stochasticity. Comparing life histories, extinction risk generally increased with increasing fecundity and decreased with higher ages of maturation. Effects of adult survival depended on age of maturation. At lower ages of maturation, extinction risk peaked at intermediate levels of adult survival, but it increased along with adult survival at higher ages of maturation. These differences were largely explained by differences in sensitivities of population growth to perturbations of life history traits. Juvenile survival rate contributed most to total demographic variance in the majority of life histories. Our general results confirmed earlier findings, suggesting that empirical patterns can be explained by a relatively simple model. Thus, basic life history information can be used to assign life history-specific sensitivity to demographic stochasticity. This is of great value when assessing the vulnerability of small populations.

Empirical and theoretical studies of population trends and extinction risks
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Empirical and theoretical approaches are needed to solve the current problem of increased extinction risk for many species. Thus, this thesis focuses on: (1) ways to estimate population trends for a large number of species, and (2) a predictive framework for identifying vulnerable populations from species traits or life history traits to allow for more proactive conservation actions. I estimated long-term population trends and range-abundance dynamics of longhorn beetles using Natural History Collections. In general, negative population trends were not accompanied by declines in range, but range increased among species with increasing populations. The analysis also exemplified how the results can be used in the red listing process. Linking life history traits and two metrics of extinction risk (population trend and red list classification) in long horn beetles showed that generation time, overwintering stage, larval host plant specialisation, adult activity period and body size were related to extinction risk, often with interaction effects between predictor variables. Variability in population size is an important factor affecting population extinction risk. I modelled the effects of demographic and environmental stochasticity on extinction risk in small populations, for a large range of life history types. Extinction risk due to demographic stochasticity increased with increasing fecundity and decreasing age of maturation, whereas effects of adult survival interacted with maturation age. Including environmental stochasticity showed that the qualitative relationship between extinction risk and life history types changed, but also that combined effects of both stochasticities on extinction risk were most significant in short-lived life histories. The results suggest that data from Natural History Collections can be used to estimate long-term population trends, and that population declines may be underestimated if estimated from changes in range. My studies also suggest that life history traits and species traits can be used to predict population vulnerability to extinction and, hence, that certain groups of species are more vulnerable to extinction than others.

Longhorn beetles in Sweden – changes in distribution and abundance over the last two hundred years
- 2010
-
Ingår i: Entomologisk tidskrift. - 0013-886X. ; 131, s. 241-512
-
Tidskriftsartikel (refereegranskat)abstract
- The abandonment of traditional agricultural practices and the introduction of large-scale industrial forestry has transformed landscapes and changed the conditions for wood-living organisms. This study examines changes in distribution and abundance of the 118 species of longhorn beetles (Col. Cerambycidae) recorded from natural habitat in Sweden over the 19th and 20th centuries, based on extensive surveys of museums, private collections and information in the literature, all in all more than 57 000 specific records compiled by 1400 collectors. The primary results are presented as maps of species’ distributions (-1900; 1901-1950; 1951-1975, and 1976-2000), population size indices (PSI s) based on species frequencies in subsets of the total material obtained by comparable collection methods, and estimates of abundance compiled from a succession of insect faunas spanning two centuries. Changing practices and preferences of collectors are examined in order to interpret the maps and indices and separate real changes of distribution and/or abundance from artefacts due to sampling biases. Appendices include the phenology of individual species and sources of data in the literature. Distributions of most species have changed little during our period of study, and 45 of 103 species are still assigned to the same category of abundance today as in the faunas from the early 19th century. Similarly, tests and interpretations of the PSIs indicate that the abundances of 31 out of 76 analysed species have been quite stable since the 1950s. Other species seem to increase - 32 are considered more abundant today than in the early 19th century faunas, and 17 of the 76 analysed species appear to have become more common since the 1950s. However, there have also been substantial negative changes: 26 species are categorised as less abundant today than in the early 19th century, and 5-10 of these have probably gone extinct. Furthermore, tests and interpretations of the PSI s indicate that 16 of 76 analysed species have decreased in abundance over the last fifty years. Some of these are associated with burnt trees, a handful develop in large diameter sun-exposed dead oak wood, others utilise dead wood of lime, a couple live in open, grazed coniferous forests, two species mainly develop in old construction wood and one species is primarily found in old-growth spruce forests. Close to half of all Swedish species of longhorn beetles are red-listed. However, our analyses indicate that few red-listed species meet the IUCN thresholds for population decline, suggesting that the thresholds are set too high to detect declining longhorn beetles (and perhaps insects more generally), but also that some red-listed species seem to increase and should be removed from the list. Our results also indicate that red-listed species whose narrow distributions have been the same for a long time may be limited by other factors than substrate availability, and therefore be more resilient to habitat change than their red-list classification suggests. Conversely, species with recently contracting ranges of distribution may be even more at risk than their threat categories imply. A final section briefly discusses monitoring of future trends and gives some suggestions on how conservation measures may be designed to better meet regional conservation needs

Oh, how we pick and choose: on theoretical constructs in subfields of ecology
- 2016
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Ecology consists of a large number of theoretical constructs, empirical patterns and methods; a pool from which applied ecology can draw ideas when exploring practical problems. Subfields of applied ecology - including pest control, conservation, and wildlife management - deal with the management of biological populations, and should therefore rest on the same ecological foundations. But is this really the case? We study this issue by analyzing recent citation rates (2010-2014) to more than 130 highly cited, classic publications, covering a wide range of topics. Using ordination methods, we find a clear clustering of journals, where conservation occupies another part of the ordination space than pest control. Classifying papers into broad topics reveals that the ordination patterns are driven by striking differences in how often ecological concepts are used in different subfields. While some patterns are easy to understand, e.g. the use of biodiversity concepts in conservation, others are left unexplained. For instance, the lack of spatial concepts and competition in pest control, predation in conservation journals, and foodweb ideas in wildlife journals are harder to understand. Microbial ecology also appears devoid of large parts of ecological theory. These patterns imply distinct divides within ecology, where subfields selectively use certain parts of ecological theory. Therefore, we argue that work in applied ecology would benefit from broader theoretical perspectives. Collaboration and inspiration across sub-disciplines could be one way to achieve this, perhaps inspiring novel research directions.

Species' traits explain differences in Red list status and long-term population trends in longhorn beetles
- 2014
-
Ingår i: Animal Conservation. - : Wiley. - 1367-9430 .- 1469-1795. ; 17, s. 332-341
-
Tidskriftsartikel (refereegranskat)abstract
- Some species are more likely to go extinct than others and this is partially due to species' traits. Therefore, it is important to establish links between traits and extinction risks. Different aspects of a species' biology also relates to different sources of threat, such as fragmented populations or low population growth rate. In a comparative study of Swedish longhorn beetles (Coleoptera: Cerambycidae), we related species' traits to two aspects of extinction risk - population decline and small/fragmented populations - measured by long-term population trends and IUCN Red list classifications. Trait relationships were analysed with generalized linear models and multi-model inference. We found that extinction risk generally increased with longer generation times, corresponding to slower life histories. Adult activity period was also related to both metrics of extinction risk, but in different ways. We also found that extinction risk increased with larval host plant specialization, but only for Red list classification. Large body size was related to increased Red list classification in species overwintering as adults, and overwintering stage also structured the effects of several other traits. Our results show that both intrinsic demographic traits and ecological traits affect extinction risks, and also suggest that risks are shaped by multiple mechanisms. Therefore, researchers should carefully choose their metric of extinction risk for comparative studies, as the Red list classification may best capture current risk, whereas population trends can be used more proactively but may reflect historical relationships between traits and extinction risk.

The many forms of beta diversity: a comment on McGill et al. and some notational suggestions
- 2017
-
Ingår i: PeerJ Preprints. - : PeerJ. - 2167-9843.
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Fundamentally, beta diversity is a measure of species turnover across time or space. In practice, it is sometimes unclear exactly what aspect of beta diversity that is implied in studies. For instance, a trend in ’spatial beta diversity’ can be used to refer to both differences in spatial beta diversity between sites, as well as a temporal trend in spatial beta diversity (at the same site). In a recent review, McGill et al. [1] provide a useful and much needed overview of different aspects of biodiversity change, and show areas where we lack knowledge. Even so, McGill et al. ignore some aspects of beta diversity and sometimes pool different types of beta diversity under the same heading. However, their review mainly focused on temporal trends in diversity, while I here want to highlight spatial patterns in temporal β -diversity (species turnover) as an important but somewhat overlooked component of biodiversity change. Furthermore, I propose a slightly modified classification and nomenclature of metrics of biodiversity change, with the aim of complementing their review. The notation used here can hopefully be useful to other authors as well.

The use of historical collections to estimate population trends: A case study using Swedish longhorn beetles (Coleoptera: Cerambycidae)
- 2010

Tidskriftsartikel (refereegranskat)abstract
- Long term data to estimate population trends among species are generally lacking. However, Natural History Collections (NHCs) can provide such information, but may suffer from biases due to varying sampling effort. To analyze population trends and range-abundance dynamics of Swedish longhorn beetles (Coleoptera: Cerambycidae), we used collections of 108 species stretching over 100 years. We controlled for varying sampling effort by using the total number of database records as a reference for non-red-listed species. Because the general frequency of red-listed species increased over time, a separate estimate of sampling effort was used for that group. We observed large interspecific variation in population changes, from declines of 60% to several hundred percent increases. Most species showed stable or increasing ranges, whereas few seemed to decline in range. Among increasing species, rare species seemed to expand their range more than common species did, but this pattern was not observed in declining species. Historically, rare species did not seem to be at larger risk of local extinction, and population declines were mostly due to lower population density and not loss of sub-populations. We also evaluated the species' declines under IUCN red-list criterion A, and four currently not red-listed species meet the suggested threshold for Near Threatened (NT). The results also suggested that species' declines may be overlooked if estimated only from changes in species range. (C) 2010 Elsevier Ltd. All rights reserved.

Unclear relationships between mean survival rate and its environmental variance in vertebrates
- 2024
-
Ingår i: Ecology and Evolution. - : Wiley. - 2045-7758. ; 14:3
-
Tidskriftsartikel (refereegranskat)abstract
- Current environmental changes may increase temporal variability of life history traits of species thus affecting their long-term population growth rate and extinction risk. If there is a general relationship between environmental variances (EVs) and mean annual survival rates of species, that relationship could be used as a guideline for analyses of population growth and extinction risk for populations, where data on EVs are missing. For this purpose, we present a comprehensive compilation of 252 EV estimates from 89 species belonging to five vertebrate taxa (birds, mammals, reptiles, amphibians and fish) covering mean annual survival rates from 0.01 to 0.98. Since variances of survival rates are constrained by their means, particularly for low and high mean survival rates, we assessed whether any observed relationship persisted after applying two types of commonly used variance stabilizing transformations: relativized EVs (observed/mathematical maximum) and logit-scaled EVs. With raw EVs at the arithmetic scale, mean–variance relationships of annual survival rates were hump-shaped with small EVs at low and high mean survival rates and higher (and widely variable) EVs at intermediate mean survival rates. When mean annual survival rates were related to relativized EVs the hump-shaped pattern was less distinct than for raw EVs. When transforming EVs to logit scale the relationship between mean annual survival rates and EVs largely disappeared. The within-species juvenile-adult slopes were mainly positive at low (<0.5) and negative at high (>0.5) mean survival rates for raw and relativized variances while these patterns disappeared when EVs were logit transformed. Uncertainties in how to interpret the results of relativized and logit-scaled EVs, and the observed high variation in EV's for similar mean annual survival rates illustrates that extrapolations of observed EVs and tests of life history drivers of survival–EV relationships need to also acknowledge the large variation in these parameters.

Evaluating temporal variation in Citizen Science Data against temporal variation in the environment
- 2014
-
Ingår i: Ecography. - : Wiley. - 0906-7590 .- 1600-0587. ; 37, s. 293-300

Tidskriftsartikel (refereegranskat)abstract
- Citizen Science Data (CSD) is increasingly contributing to the assessment of biodiversity and ecosystems. However, there is a need to evaluate the usefulness of CSD for different purposes. Ideally, CSD from populations should be evaluated against independent population data collected using a proper sampling design, but such data are lacking for almost all species. We propose an approach for evaluating CSD against environmental data. First, an evaluation model is formulated based on knowledge of how environmental variables affect population dynamics. Second, the hypotheses of the evaluation model are tested statistically. Support for the evaluation model is interpreted as support for the CSD. We applied the approach to six longhorn beetle species using Swedish data from 1930-2000. The evaluation model assumed that early summer temperature affects larval development time. We found support for the evaluation model in two species, and some evidence in its favour in one species. This suggests that the CSD from these species reflect true inter-annual variation. We also found statistical evidence for population trends in three to four species. In two of these, the evaluation model was supported thus providing particular support for the trend estimates. Lack of support for the evaluation model may be due to biological inaccuracy, the general characteristics of CSD, or low resolution of the environmental evaluation data. We also discuss alternative environmental data for evaluating CSD.

Tidskriftsartikel (refereegranskat)abstract
- BioMAX is the first macromolecular crystallography beamline at the MAX IV Laboratory 3 GeV storage ring, which is the first operational multi-bend achromat storage ring. Due to the low-emittance storage ring, BioMAX has a parallel, high-intensity X-ray beam, even when focused down to 20 μm × 5 μm using the bendable focusing mirrors. The beam is tunable in the energy range 5-25 keV using the in-vacuum undulator and the horizontally deflecting double-crystal monochromator. BioMAX is equipped with an MD3 diffractometer, an ISARA high-capacity sample changer and an EIGER 16M hybrid pixel detector. Data collection at BioMAX is controlled using the newly developed MXCuBE3 graphical user interface, and sample tracking is handled by ISPyB. The computing infrastructure includes data storage and processing both at MAX IV and the Lund University supercomputing center LUNARC. With state-of-the-art instrumentation, a high degree of automation, a user-friendly control system interface and remote operation, BioMAX provides an excellent facility for most macromolecular crystallography experiments. Serial crystallography using either a high-viscosity extruder injector or the MD3 as a fixed-target scanner is already implemented. The serial crystallography activities at MAX IV Laboratory will be further developed at the microfocus beamline MicroMAX, when it comes into operation in 2022. MicroMAX will have a 1 μm × 1 μm beam focus and a flux up to 1015 photons s with main applications in serial crystallography, room-temperature structure determinations and time-resolved experiments.

Hatching failure and accumulation of organic pollutants through the terrestrial food web of a declining songbird in Western Europe

Tidskriftsartikel (refereegranskat)abstract
- Population growth in passerine birds is largely driven by fecundity. If fecundity is affected, for instance by hatching failure, populations may decline. We noted high hatching failure of up to 27% per year in relict populations of the Northern wheatear (Oenanthe oenanthe) in The Netherlands, a strongly declining, migratory passerine in Europe. This hatching failure itself can cause population decline, irrespective of other adverse factors. Additionally, we investigated the cause of hatching failure. Unhatched eggs showed egg yolk infections or embryonic malformations, part of which is associated with the actions of dioxin-like compounds (DLCs). Indeed, DLCs appear to bioaccumulate in the local foodweb, where the soil contained only background concentrations, similar to those found at many other locations. DLC concentrations in Dutch eggs were six-fold higher than those in a reference population in Sweden, where egg failure was only 6%. However, Northern wheatears appear to be only moderately sensitive to the actions of DLCs, because of their specific Ah-receptor type which may moderate the receptor mediated effects of DLCs. This indicates that the concentrations of DLCs, although elevated, may not have caused the embryo malformations or the low hatching rates. We discuss whether other toxins may be important or imbalances in the nutrition and if inbreeding may play a larger role than expected.

Konferensbidrag (refereegranskat)abstract
- While normalized bibliometric indicators are expected to resolve the subject-field differences between organizations in research evaluations, size still matters. Furthermore, research organizations, policymakers and research funding providers tend to use benchmark units as points of comparison for a given research center in order to understand and monitor its development and performance. In addition to monitoring and evaluations, the identification of comparable benchmark organizations can also be used to pinpoint potential collaboration partners or competitors. Therefore, methods to identify benchmark research units are of practical significance. However, few studies have investigated this problem. This study aims to propose a bibliometric method to identify benchmarks. We define a benchmark as a well-connected research environment, in which researchers work on similar topics and publish a similar number of publications compared to a given research center during the same period. Three essential attributes for the evaluation of benchmarks are research topics, output, and coherence. We apply this strategy to a Swedish research center, and examine the effectiveness of the method.

- While normalized bibliometric indicators are expected to resolve the subject-field differences between organizations in research evaluations, the identification of reference organizations working on similar researchtopics is still of importance. Research organizations, policymakers and research funders tend to use benchmark units as points of comparison for a certain research unit in order to understand and monitor its development and performance. In addition, benchmarkorganizations can also be used to pinpoint potential collaboration partners or competitors. Therefore, methods for identifying benchmark research units are of practical significance. Even so, few studies have further explored this problem. This study aims to propose a bibliometric approach for the identification of benchmark units. We define an appropriate benchmark as a well-connected research environment, in which researchers investigate similar topics and publish a similar number of publications compared to a given research organization during the same period. Four essential attributes for the evaluation of benchmarks are research topics, output, connectedness, and scientific impact. We apply this strategy to two research organizations in Sweden and examine the effectiveness of the proposed method. Identified benchmark units are evaluated by examining the research similarity and the robustness of various measures of connectivity.
