title: Combined influence of intrinsic and environmental factors in shaping productivity in a small pelagic gull, the black-legged kittiwake Rissa tridactyla

description: While we have a good understanding in many systems of the effects of
 single variable changes on organisms, we understand far less about how
 variables act in concert to affect living systems, where interactions
 among variables can lead to unanticipated results. We used mixed-effect
 models to evaluate the effects of multiple variables that we expected to
 play a role in the early reproductive stages of a North Pacific seabird,
 the black-legged kittiwake Rissa tridactyla, during 1992–2008 using data
 collected on known-aged individuals. Our work revealed the potential for
 contrasting stressor effects across successive stages of reproduction.
 Bird age, timing of egg laying, and winter ENSO conditions best explained
 individual laying success, such that laying success was greater when
 parents were older, the average winter ENSO index was positive (as occurs
 during El Niño episodes), and the median laying date for the colony was
 earlier. Age and salmon run timing (a proxy for predator presence at the
 colony) best explained hatching success, such that hatching success was
 greater when parents were older and when salmon runs were early.
 Identifying such differential effects of multiple stressors across
 consecutive reproductive stages can greatly enhance our ability to
 interpret trends and manage populations in the face of changes currently
 occurring in living systems.

title: Threats from the air: damselfly predation on diverse prey taxa

description: 1. To understand the diversity and strength of predation in natural
 communities, researchers must quantify the total amount of prey species in
 the diet of predators. Metabarcoding approaches have allowed widespread
 characterization of predator diets with high taxonomic resolution. To
 determine the wider impacts of predators, researchers should combine DNA
 techniques with estimates of population size of predators using
 mark-release-recapture (MRR) methods, and with accurate metrics of food
 consumption by individuals. 2. Herein, we estimate the scale of predation
 exerted by four damselfly species on diverse prey taxa within a
 well-defined 12-ha study area, resolving the prey species of individual
 damselflies, to what extent the diets of predatory species overlap, and
 which fraction of the main prey populations are consumed. 3. We identify
 the taxonomic composition of diets using DNA metabarcoding and quantify
 damselfly population sizes by MRR. We also use predator-specific estimates
 of consumption rates, and independent data on prey emergence rates to
 estimate the collective predation pressure summed over all prey taxa and
 specific to their main prey (non-biting midges or chironomids) of the four
 damselfly species. 4. The four damselfly species collectively consumed a
 prey mass equivalent to roughly 870 (95% CL 410–1,800) grams, over two
 months. Each individual consumed 29%-66% (95% CL 9.4–123) of its body
 weight during its relatively short life span (2.1-4.7 days 95% CL
 0.74–7.9) in the focal population. This predation pressure was widely
 distributed across the local invertebrate prey community, including 4
 classes, 19 orders, and ca. 140 genera. Different predator species showed
 extensive overlap in diets, with an average of 30% of prey shared by at
 least two predator species. 5. Of the available prey individuals in the
 widely-consumed family Chironomidae, only a relatively small proportion
 (0.76%; 95% CL 0.35%–1.61%) were consumed. 6. Our synthesis of population
 sizes, per-capita consumption rates and taxonomic distribution of diets
 identifies damselflies as a comparatively minor predator group of aerial
 insects. As the next step, we should add estimates of predation by larger
 odonate species, and experimental removal of odonates, thereby
 establishing the full impact of odonate predation on prey
 communities.

title: From antagonism to synergism: extreme differences in stressor interactions in one species

description: Interactions between stressors are involved in the decline of wild species
 and losses of managed ones. Those interactions are often assumed to be
 synergistic, and per se of the same nature, even though susceptibility can
 vary within a single species. However, empirical measures of interaction
 effects across levels of susceptibility remain scarce. Here, we show clear
 evidence for extreme differences in stressor interactions ranging from
 antagonism to synergism within honeybees, Apis mellifera. While female
 honeybee workers exposed to both malnutrition and the pathogen Nosema
 ceranae showed synergistic interactions and increased stress, male drones
 showed antagonistic interactions and decreased stress. Most likely sex and
 division of labor in the social insects underlie these findings. It
 appears inevitable to empirically test the actual nature of stressor
 interactions across a range of susceptibility factors within a single
 species, before drawing general conclusions.

title: Variation in butterfly diapause duration in relation to voltinism suggests adaptation to autumn warmth, not winter cold

description: 1. The life cycles of animals vary in relation to local climate, as a
 result of both direct environmental effects and population-level variation
 in plastic responses. Insects often respond to the approach of winter by
 entering diapause, a hormonally programmed resting state where development
 is suspended and metabolism suppressed. Populations often differ in the
 duration of diapause, but the adaptive reasons for this are unclear. 2. We
 performed a common-garden overwintering experiment with respirometric
 measurements in order to investigate the progression of diapause in the
 butterfly Pararge aegeria. Both the duration of diapause and the depth of
 metabolic suppression were shown to vary between populations. 3. In
 contrast to previous results from various insects, diapause duration did
 not correspond to the local length of winter. Instead, the observed
 pattern was consistent with a scenario in which diapause duration is
 primarily a product of selection for suppressed metabolism during warm
 autumn conditions. The relationship between optimal diapause duration and
 the length of the warm season is complicated by variation in the number of
 yearly generations (voltinism). 4. These results shed new light on
 variation in diapause ecophysiology, and highlight voltinism as an
 integrated product of selection at multiple points in the seasonal cycle.
description: Three-part dataset: 1) Main experiment:
 diapausing butterfly pupae (<em>Pararge aegeria</em>) were
 subjected to different durations of cold exposure. The date and success
 rate of adult eclosion was noted, and weight was measured at the beginning
 and end of the cold treatment. Metabolic measurements were carried out on
 a subset of individuals at regular intervals. 2) An
 additional set of metabolic measurements were carried out on nondiapausing
 pupae during their development into adults, and measurements were made at
 matching timepoints for diapausing pupae. 3) The
 seasonal cycle of each population was reconstructed to provide adaptive
 context for the laboratory results, using local temperature data,
 citizen-science observations of adult <em>P. aegeria</em>, and
 a mechanistic life cycle model previously described by
 Lindestad <em>et al</em>. 2019
 (<em>Ecology</em>).

title: Anthropogenic noise impairs foraging for cryptic prey via cross-sensory interference

description: Anthropogenic noise levels are globally rising with profound impacts on
 ecosystems and the species that live in them. Masking or distraction by
 noise can interfere with relevant sounds and thereby impact ecological
 interactions between individuals of the same or different
 species.  Predator-prey dynamics are particularly likely
 to be influenced by rising noise levels, with important population- and
 community-level consequences, as species may differentially adapt to noise
 disturbance. Acoustic noise can, however, also impair the use of visual
 information by animals through the process of cross-sensory interference,
 possibly impacting species interactions that have so far been largely
 ignored by noise impact studies. Here we assessed how noise affected the
 performance of Great tit (Parus major) foraging on cryptic
 prey. Birds trained individually to search for paper
 moths differing in the level of camouflage with the test
 background were tested in the presence and absence of
 noise. We found that noise significantly increased approach and attack
 latencies, but that the effect depended on the level of crypsis. Noise
 increased latencies for cryptic prey targets, but not for conspicuous and
 colour-matched prey targets. Our results show that noise can interfere
 with the processing of visual information, particularly in difficult tasks
 such as separating objects from a similar looking background. These
 results have important ecological and evolutionary implications as they
 demonstrate how globally rising anthropogenic noise levels can influence
 the arms race between predators and prey across sensory domains.

title: Habitat use, interspecific competition, and phylogenetic history shape the evolution of claw and toepad morphology in Lesser Antillean anoles

description: Ecologically functional traits are the product of several, at times
 opposing, selective forces. Thus, ecomorphological patterns can be
 disrupted locally by biotic interactions such as competition and may not
 be consistent across lineages. Here, we studied the evolution of claws and
 toepads in relation to macrohabitat (vegetation), use of structural
 microhabitat (perch height), and congeneric competition for two
 distantly-related Lesser Antillean anole clades: the bimaculatus and
 roquet series. We collect univariate and geometric morphometric data from
 254 individuals across 22 species to test the hypotheses that (1)
 functional morphology should covary with both vegetation and perch height
 and that (2) the presence of a competitor may disrupt such covariation.
 Our data show predictable associations between morphology and macrohabitat
 on single-species islands but not when a congeneric competitor is present.
 The outcomes of competition differ between series, however.  In
 the bimaculatus series, species with a sympatric congener diverge in claw
 and toepad traits consistent with functional predictions, whereas roquet
 series anoles show either no association between habitat and morphology or
 the opposite pattern. Our results demonstrate that ecomorphological
 patterns across macrohabitats can be disrupted by competition-driven
 microhabitat partitioning and that specific morphological responses to
 similar ecological pressures can vary between lineages.

title: Using local ecological knowledge as evidence to guide management: A community-led harvest calculator for muskoxen in Greenland

description: Indigenous peoples manage or have tenure rights on over a quarter of the
 world’s land surface. While there is growing interest in “evidence-based”
 natural resource management, there are few documented experiences with
 “evidence-based” practice in community-managed lands. We explore the
 evidence required for decisions about harvesting of a community-managed
 muskox herd in Greenland, and the collaboration needed to acquire this
 evidence. We present the development, application and outcome of a
 user-friendly demographic model - a harvest calculator - and we show how
 Local Ecological Knowledge was used throughout the process and combined
 with scientific knowledge. The community members identified suitable
 harvest scenarios with the use of the calculator. The calculator’s
 predictions corresponded with their own perceptions of declining numbers
 of muskox bulls and suggested that reversal was possible under an
 alternative harvest scenario. As a result, the community members used the
 findings to request a revised muskox harvest quota, which gained immediate
 approval by the government. We draw on our experience to propose where
 community-led harvest calculators can be useful. Community-led harvest
 calculators can help Indigenous and local communities develop economically
 within environmentally sustainable limits, while at the same time
 providing community members a ‘voice’ in natural resource governance. An
 effective local management regime will require the sustained application
 of this tool.

title: Generating fast sparse matrix vector multiplication from a high level generic functional IR

description: Usage of high-level intermediate representations promises the generation
 of fast code from a high-level description, improving the productivity of
 developers while achieving the performance traditionally only reached with
 low-level programming approaches. High-level IRs come in two flavors: 1)
 domain-specific IRs designed to express only for a specific application
 area; or 2) generic high-level IRs that can be used to generate
 high-performance code across many domains. Developing generic IRs is more
 challenging but offers the advantage of reusing a common compiler
 infrastructure various applications. In this paper, we extend a generic
 high-level IR to enable efficient computation with sparse data structures.
 Crucially, we encode sparse representation using reusable dense building
 blocks already present in the high-level IR. We use a form of dependent
 types to model sparse matrices in CSR format by expressing the
 relationship between multiple dense arrays explicitly separately storing
 the length of rows, the column indices, and the non-zero values of the
 matrix. We demonstrate that we achieve high-performance compared to spare
 low-level library code using our extended generic high-level code
 generator. On an Nvidia GPU, we outperform the highly tuned Nvidia
 cuSparse implementation of SpMV multiplication across 28 sparse matrices
 of varying sparsity on average by $1.7\times$.

title: Minor neuropsychological deficits in patients with subjective cognitive decline

description: Objective: To determine the nature and extent of minor neuropsychological
 deficits in patients with subjective cognitive decline (SCD) and their
 association with cerebrospinal fluid (CSF) biomarkers of Alzheimer’s
 disease (AD). Method: We analyzed data from n=449 cognitively normal
 participants (n=209 healthy controls, n=240 SCD patients) from an interim
 data release of the German Center for Neurodegenerative Diseases
 Longitudinal Cognitive Impairment and Dementia Study (DELCODE). An
 extensive neuropsychological test battery was applied at baseline for
 which we established a latent, five cognitive domain factor structure
 comprising learning & memory, executive functions, language
 abilities, working memory and visuospatial functions. We compared groups
 regarding global and domain-specific performance and correlated
 performance with different CSF markers of AD pathology. Results: We
 observed worse performance (Cohen’s d≈0.25-0.5, adjusted for age-, sex
 differences with ANCOVA) in global performance, memory, executive
 functions and language abilities for the SCD group compared to healthy
 controls. In addition, worse performance in these domains was moderately
 (r≈0.3) associated with lower CSF-Aβ42/40 and CSF-Aβ42/ptau181 in the
 whole sample and specifically in the SCD subgroup. Conclusions: Within the
 spectrum of clinically unimpaired (i.e., “pre- mild cognitive impairment”)
 cognitive performance, SCD is associated with minor deficits in memory,
 executive function and language abilities. The association of these subtle
 cognitive deficits with AD CSF biomarkers speaks to their validity and
 potential use for the early detection of underlying preclinical AD.

title: Data from: A randomized, placebo-controlled phase 2 trial of laquinimod in primary progressive multiple sclerosis

description: Objective: To evaluate efficacy, safety, and tolerability of laquinimod in
 patients with primary progressive multiple sclerosis (PPMS). Methods: In
 the randomized, double-blind, placebo-controlled, phase 2 study ARPEGGIO
 (A Randomized Placebo-controlled trial Evaluating laquinimod in PPMS,
 Gauging Gradations In MRI and clinical Outcomes), eligible PPMS patients
 were randomized 1:1:1 to receive once-daily oral laquinimod 0.6 mg or 1.5
 mg or matching placebo. Percentage brain volume change (PBVC; primary
 endpoint) from baseline to week 48 was assessed by MRI. Secondary and
 exploratory endpoints included clinical and MRI measures. Efficacy
 endpoints were evaluated using a predefined, hierarchical statistical
 testing procedure. Safety was monitored throughout the study. The
 laquinimod 1.5 mg dose arm was discontinued on January 1, 2016 due to
 findings of cardiovascular events. Results: 374 patients were randomized
 to laquinimod 0.6 mg (n = 139) or 1.5 mg (n = 95) or placebo (n = 140).
 ARPEGGIO did not meet the primary endpoint of significant treatment effect
 with laquinimod 0.6 mg versus placebo on PBVC from baseline to week 48
 (adjusted mean difference = 0.016%, p = 0.903). Laquinimod 0.6 mg reduced
 the number of new T2 brain lesions at week 48 (risk ratio = 0.4; 95%
 confidence interval, 0.26–0.69; p = 0.001). Incidence of adverse
 events was higher among patients treated with laquinimod 0.6 mg (83%)
 versus laquinimod 1.5 mg (66%) and placebo (78%). Conclusions: Laquinimod
 0.6 mg did not demonstrate a statistically significant effect on brain
 volume loss in PPMS at week 48.

title: Sounds of senescence: Male swamp sparrows respond less aggressively to the song of older individuals

description: Age-related changes in assessment signals occur in a diverse array of
 animals, including humans. Age-related decline in vocal quality in humans
 is known to affect perceived attractiveness by potential mates and voters,
 but whether such changes have functional implications for non-human
 animals is poorly understood. Most studies of age-related change in animal
 signals focus on increases in signal quality that occur soon after the age
 of first breeding (“delayed maturation”), but a few have shown that signal
 quality declines in older individuals after a mid-life peak (“behavioral
 senescence”). Whether other individuals are able to detect this senescent
 decline of assessment signals has not previously been tested. Here we use
 playback experiments to show that wild male swamp sparrows (Melospiza
 georgiana) respond more aggressively to songs from two-year-old males as
 compared to songs from the same males when they are ten years old.
 Senescence in signals that, like birdsong, affect reproductive success
 though intra-sexual competition or mate choice may be of evolutionary
 significance.
