title: Canada's first known dinosaurs: Palaeontology and collecting history of upper Cretaceous vertebrates in Southern Alberta and Saskatchewan, 1874-1889

description: The early collecting history of dinosaurs and other fossil vertebrates in
 Western Canada during the 1870s and 1880s is poorly documented. Initial
 finds were made by the British North American Boundary Commission and the
 Geological Survey of Canada in modern Saskatchewan and Alberta but, beyond
 a few well-publicized examples, little is known about precisely what was
 found and where. Much of the collected material is now housed in the
 collections of the Canadian Museum of Nature in Gatineau, Quebec, and a
 recent survey of these historic finds allows for the first comprehensive
 narrative regarding their identity and procurement. The collection is
 heavily biased towards vertebral centra and phalanges, reflective of both
 taphonomic and collecting biases. Given current understanding of Upper
 Cretaceous assemblages of North America, ornithomimids and small theropods
 are overrepresented, whereas ceratopsids and ankylosaurs are
 underrepresented. Fossils from the Belly River Group are best represented,
 after repeated visits to the areas of present-day Dinosaur Provincial Park
 and Ross Coulee near Irvine, Alberta. Taxonomic identification of the
 material has yielded numerous first Canadian occurrences, in addition to
 some first global occurrences. The latter include the first ever
 occurrences of Caenagnathidae (1884) and Thescelosauridae (1889). The
 Upper Cretaceous fossil record of Western Canada is among the richest in
 the world, and has been thoroughly studied over the last century. These
 fossils have informed our understanding of dinosaur behaviour, taphonomy,
 ecology, diversity dynamics, and extinction, among other aspects. But,
 like the animals themselves, the story of Canada’s dinosaur-hunting legacy
 had humble beginnings—a story that has not been fully revealed before now.

title: Alternative pathways to diversity across ecologically distinct lizard radiations

description: Aim: Lizard assemblages vary greatly in taxonomic, ecological and
 phenotypic diversity, yet the mechanisms that generate and maintain these
 patterns at a macroecological scale are not well understood. We aimed to
 characterize the ecological and environmental drivers of species richness
 patterns in the context of macroecological theory for ten independent
 lizard radiations. Location: Global Time Period: Present-day Major taxa:
 Lizards Methods: We analyzed patterns of species and ecological trait
 diversity in ten ecologically distinct and widely distributed clades
 encompassing nearly all known lizard species. Using recently published
 spatial, phylogenetic, and ecological trait datasets, we built spatially
 explicit structural equation models to ask whether species diversity was
 directly or indirectly related to functional divergence or convergence
 within communities, and with features of the environment, including
 measures of productivity, complexity, and harshness. Results: Our results
 show that high species diversity is achieved via different pathways in
 different lizard clades, with both functionally divergent and convergent
 assemblages harboring high diversity in different clades. More generally,
 we also find common, positive effects of temperature, productivity, and
 topography on species richness within lizard clades. Main Conclusions:
 Thermal constraints, topographic complexity, and spatial structuring of
 functional diversity help explain the presence of highly diverse lizard
 assemblages, suggesting the importance of environmental filters in shaping
 present-day diversity and assemblage structure. Our results show how
 different pathways to high richness in different clades have contributed
 to the overall global pattern of species richness in reptiles.

title: Neurofilament light as a biomarker in traumatic brain injury

description: Objective: To determine whether serum neurofilament light (NfL)
 correlates with CSF NfL, traumatic brain injury (TBI) diagnosis, injury
 severity, brain volume, and diffusion tensor imaging (DTI) estimates of
 traumatic axonal injury (TAI). Methods: Participants were
 prospectively enrolled in Sweden and the United States between 2011 and
 2019. The Swedish cohort included 45 hockey players with acute concussion
 sampled at 6 days, 31 with repetitive concussion with persistent
 postconcussive symptoms (PCS) assessed with paired CSF and serum (median
 1.3 years after concussion), 28 preseason controls, and 14 nonathletic
 controls. Our second cohort included 230 clinic-based participants (162
 with TBI and 68 controls). Patients with TBI also underwent serum,
 functional outcome, and imaging assessments at 30 (n=30), 90 (n=48), and
 180 (n=59) days and 1 (n=84), 2 (n=57), 3 (n= 46), 4 (n = 38), and 5 (n =
 29) years after injury. Results: In athletes with paired
 specimens, CSF NfL and serum NfL were correlated (r =
 0.71, p &lt; 0.0001). CSF and serum NfL
 distinguished players with PCS &gt;1 year from PCS ≤1 year
 (area under the receiver operating characteristic curve [AUROC] 0.81 and
 0.80). The AUROC for PCS &gt;1 year vs preseason controls was 0.97. In
 the clinic-based cohort, NfL at enrollment distinguished patients with
 mild from those with moderate and severe TBI (p &lt; 0.001
 and p = 0.048). Serum NfL decreased over the course of 5
 years (ß = −0.09 log pg/mL, p &lt; 0.0001)
 but remained significantly elevated compared to controls. Serum NfL
 correlated with measures of functional outcome, MRI brain atrophy, and DTI
 estimates of TAI. Conclusions: Serum NfL shows promise as a
 biomarker for acute and repetitive sports-related concussion and patients
 with subacute and chronic TBI. Classification of Evidence: This
 study provides Class III evidence that increased concentrations of NfL
 distinguish patients with TBI from controls.

title: Data from: Dinoflagellates with relic endosymbiont nuclei as models for elucidating organellogenesis

description: Nucleomorphs are relic endosymbiont nuclei so far found only in two algal
 groups, cryptophytes and chlorarachniophytes, which have been studied to
 model the evolutionary process of integrating an endosymbiont alga into a
 host-governed plastid (organellogenesis). However, past studies suggested
 that DNA transfer from the endosymbiont to host nuclei had already ceased
 in both cryptophytes and chlorarachniophytes, implying that the
 organellogenesis at the genetic level has been completed in the two
 systems. Moreover, we have yet to pinpoint the closest free-living
 relative of the endosymbiotic alga engulfed by the ancestral
 chlorarachniophyte or cryptophyte, making it difficult to infer how
 organellogenesis altered the endosymbiont genome. To counter the above
 issues, we need novel nucleomorph-bearing algae, in which
 endosymbiont-to-host DNA transfer is on-going and for which
 endosymbiont/plastid origins can be inferred at a fine taxonomic scale.
 Here, we report two previously undescribed dinoflagellates, strains MGD
 and TGD, with green algal endosymbionts enclosing plastids as well as
 relic nuclei (nucleomorphs). We provide evidence for the presence of DNA
 in the two nucleomorphs and the transfer of endosymbiont genes to the host
 (dinoflagellate) genomes. Furthermore, DNA transfer between the host and
 endosymbiont nuclei was found to be in progress in both the MGD and TGD
 systems. Phylogenetic analyses successfully resolved the origins of the
 endosymbionts at the genus level. With the combined evidence, we conclude
 that the host-endosymbiont integration in MGD/TGD is less advanced than
 that in cryptophytes/chrorarachniophytes, and propose the two
 dinoflagellates as models for elucidating organellogenesis.

title: EMST Panel 1 Finite Element Model [supporting data]

description: In partnership with Arconic and Embraer, the Federal Aviation Administration (FAA) is assessing emerging metallic structures technologies (EMST) using the FAA’s Full-Scale Aircraft Structural Test Evaluation and Research (FASTER) facility. In this collaborative effort, full-scale fuselage panel test data will be obtained to assess the effect of EMST fuselage concepts on damage tolerance performance as compared to the current baseline aluminum fuselage structures located on the crown of a typical single-aisle aircraft forward of the wing. Several technologies will be considered in the scope of the project, including advanced aluminum–lithium alloys, selective reinforcement using fiber metal laminates, and advanced joining processes, such as friction stir welding. Data from this study will be used to verify improved weight and structural safety performance of EMST and to assess the adequacy of existing airworthiness standards and guidance needed for the implementation of arising technologies and their impact on future designs. Results from the first baseline panel test are summarized in this technical note and will be compared to future tests on advanced panels containing varying EMST to assess the damage-tolerance performance.

title: Data from: Uninhibited chickens: ranging behavior impacts motor self-regulation in free-range broiler chickens (Gallus gallus domesticus)

description: Inhibiting impulsive, less flexible behaviors is of utmost importance for
 individual adaptation in an ever-changing environment. However,
 problem-solving tasks may be greatly impacted by individual differences in
 behavior, since animals with distinct behavioral types perceive and
 interact with their environment differently, resulting in variable
 responses to the same stimuli. Here, we tested whether and how differences
 in ranging behavior of free-range chickens affect motor self-regulation
 performance during a cylinder task. For this task, subjects must refrain
 from trying to reach a food reward through the walls of a transparent
 cylinder and detour to its open sides, as a sign of inhibition. Free-range
 chickens exhibited an overall low performance in the motor self-regulation
 task (31.33% ± 13.55% of correct responses), however high rangers showed
 significantly poorer performance than the low rangers (23.75% ± 9.16% vs
 40% ± 12.90%, respectively). These results give further support to the
 impacts of individual behavioral differences on cognitive performances.
 This is the first demonstration to our knowledge of a relationship between
 exploratory tendencies and motor self-regulation for an avian species.

title: Data from: Drying determines the temporal dynamics of stream invertebrate structural and functional beta diversity

description: Assembly processes shaping ecological communities can vary over time
 following variations of environmental conditions at different scales. Such
 temporal dynamism is exacerbated by climate change and increasing extreme
 events, and recent evidence suggests that, in turn, community composition
 and functions can vary substantially. However, empirical relationships
 between the spatio-temporal dynamics of communities and that extreme
 events altering ecosystems are poorly investigated. We quantified the
 temporal dynamics of stream invertebrate communities over two years across
 11 river basins prone to drying, covering a large geographical area of
 France. We tested predictions on the influence of the spatial arrangement
 and temporal dynamics of drying events across river networks. Combining a
 high temporal resolution of community description from taxonomic and
 functional perspectives, we quantified beta diversity over time and space
 and partitioned them into additive components: replacement of taxa and
 richness difference. Frequency and duration of drying events were
 precisely quantified and basins were classified based on the location of
 the drying events. We found a strong influence of the spatial drying
 pattern on the dissimilarities of community composition between sites. The
 high temporal variability of community structure was directly related to
 the frequency and duration of drying events. This temporal dynamism of
 communities was also strongly affected by the spatial drying pattern,
 indicating that fragmentation had a stronger effect on recolonisation
 processes for upstream-drying basins. Finally, biological traits were
 unevenly distributed in space and time, suggesting a lack of functional
 redundancy that could have strong implications for ecosystem functions and
 services. The high temporal dynamics of communities highlighted in this
 study challenge the current definition of reference conditions in
 intermittent rivers, and the community sensitivity to frequency and
 duration of drying suggest that climate change might lead community
 dynamics to be increasingly driven by stochastic environmental
 variability.

title: Climate and host genotype jointly shape tree phenology, disease levels and insect attacks

description: One of the best known ecological consequences of climate change is the
 advancement of spring phenology. Yet, we lack insights into how changes in
 climate interact with intraspecific genetic variation in shaping spring
 and autumn phenology, and how such changes in phenology will translate
 into seasonal dynamics of tree-associated organisms. To elucidate the
 impact of warming and tree genotype on spring and autumn phenology, as
 well as the consequences for the population dynamics of a fungal pathogen
 (Erysiphe alphitoides) and plant-feeding insect (Tuberculatus annulatus),
 we conducted an active field heating experiment using grafts of five oak
 genotypes (Quercus robur). We found that experimental warming generally
 advanced oak bud burst in spring and delayed leaf senescence in autumn,
 while additional variation was explained by tree genotype and
 warming-by-genotype interactions. Warming or tree genotype did not affect
 disease levels at the beginning of the season, but shaped both disease
 levels and aphid density during the latter part of the season. Overall,
 our findings demonstrate that elevated temperature and genetic variation
 affect spring and autumn phenology, as well as the seasonal dynamics of
 higher trophic levels. Such effects may be either direct (i.e. temperature
 affecting tree phenology and attack independently) or indirect (as due to
 climate-induced changes in plant traits or the synchrony between trees and
 their attackers). To achieve a predictive understanding of the ecological
 responses and potential evolutionary changes of natural food webs in
 response to climate warming, we should merge the frameworks of global
 warming and community genetics.
