title: Data from: Floral isolation and pollination in two hummingbird-pollinated heliconias data

description: Differences in feeding performance and aggressive abilities between
 species and sexes of hummingbirds are often associated with the
 partitioning of their food sources, but whether such partitioning results
 in floral isolation (reproductive isolation at the stage of pollination)
 has received little attention. We examined components of floral isolation
 and pollinator effectiveness of Heliconia caribaea and H. bihai on the
 island of Dominica, West Indies. The short flowers of H. caribaea match
 the short bills of male Anthracothorax jugularis, its primary pollinator,
 whereas the long flowers of H. bihai match the long bills of female A.
 jugularis, its primary pollinator. In pollination experiments, both sexes
 of A. jugularis were equally effective at pollinating the short flowers of
 H. caribaea, which they preferred to H. bihai, whereas females were more
 effective at pollinating the long flowers of H. bihai. Moreover, an
 average difference in length of 12 mm between H. caribaea and H. bihai
 flowers did not prevent heterospecific pollen transfer, and both sexes
 transported pollen between the two plant species. In field studies using
 powdered dyes as pollen analogs, however, heterospecific pollen transfer
 was minimal, with only 2 of 168 flowers receiving dye from the other
 species. The length of H. bihai flowers acted as an exploitation barrier
 to male A. jugularis, which were unable to completely remove nectar from
 88% of the flowers they visited. In contrast, interference competition
 combined with high floral fidelity through traplining prevented female A.
 jugularis from transferring pollen between the two Heliconia species. A
 combination of exploitation barriers, interference and exploitative
 competition, and pollinator preferences maintains floral isolation between
 these heliconias, and may have contributed to the evolution of this
 hummingbird-plant system.

title: Data from: The Odonate Phenotypic Database, a new open data resource for comparative studies of an old insect order

description: We present The Odonate Phenotypic Database (OPD): an online data resource
 of dragonfly and damselfly phenotypes (Insecta: Odonata). Odonata is a
 relatively small insect order that currently consists of about 6400
 species belonging to 32 families. The database consists of a variety of
 morphological, life-history and behavioral traits, and biogeographical
 information collected from literature sources. We see taxon-specific
 phenotypic databases from Odonata and other organismal groups as becoming
 an increasing valuable resource in comparative studies. Our database has
 phenotypic records for 1011 of all 6400 known odonate species. The
 database is accessible at http://www.odonatephenotypicdatabase.org/ and
 also uploaded as a supporting information file with this paper. Update on
 November 6 2020 A total of 397 new taxa have been added to the database
 (aside from wing pigmentation data, many taxa have information on
 morphology, distribution and behaviour). Updated (validated) pigmentation
 status for 20 taxa (for these taxa, columns concerning wing pigment have
 been changed compared to the original opdb‐file, while all other columns
 have not been changed).

title: Data from: Additive effects of nurse and facilitated plants on ecosystem functions

description: 1. Nurse plants drive the assembly of facilitated communities and commonly
 promote plant-soil feedbacks, and are thus recognized as key engineers in
 abiotically stressful ecosystems. The literature neglects however, the
 role of the communities which benefit from the presence of the nurse as
 contributors to soil ecosystem functions. We hypothesized that the nurse
 and its beneficiaries synergistically enhance essential ecosystem
 functions mediated by soil microbiota. 2. To track how plant-plant
 facilitation impacts plant-soil feedbacks, we selected three nurse species
 in semi-arid mine tailings and defined three microsites (open space, nurse
 canopy, nurse + facilitated canopy). In each microsite, we quantified 18
 abiotic and biotic variables associated with four functions: reduction of
 climatic stress, reduction of edaphic stress, soil fertility and soil
 microbial productivity (decomposition and nutrient cycling). 3. Litter
 biomass increased from open spaces to the microsite beneath the nurses,
 and further beneath the nurses and their beneficiaries. Litter biomass was
 a good predictor of both the reduction in climatic stress and increase in
 edaphic stress (likely owing to metal bioaccumulation). We attributed
 increments in soil organics and heterotrophic respiration beneath the
 nurses and their beneficiaries, compared to nurses alone, to biomass
 effects through increased litter deposition. Variation in fertility and
 microbial productivity among microsites shaped by the nurses and their
 facilitated communities was attributed to both diversity and biomass
 effects. In particular, fertility was promoted beneath phenotypically
 diverse facilitated communities, as inferred from ten above- and
 belowground traits. However, microbial productivity increased at low
 levels of root biomass likely due to reduced plant-microbe competition for
 nutrients. 4. Synthesis. Our results show that facilitated plant
 communities sheltered by nurse species relieve local abiotic stress and
 promote plant-microbe interactions, both through biomass and biodiversity
 effects. These observations shift the conception of facilitated species
 from simple beneficiaries of the nurse’s effects, to co-drivers of
 essential ecosystem functions.

title: Data from: Headache after ischemic stroke: a systematic review and meta-analysis

description: Objective: Headache associated with ischemic stroke is poorly understood.
 To gain further insight, we systematically reviewed studies examining the
 prevalence and characteristics of new onset post-stroke headache. Methods:
 Medline and PubMed databases were queried. 1812 articles were identified.
 Of these, 50 were included in this systematic review. Twenty were included
 in a meta-analysis and meta-regression. Results: Headache occurred in
 6-44% of the ischemic stroke population. Most headaches had tension-type
 features, were moderate to severe and became chronic in nature.
 Meta-analysis using an inverse-variance heterogeneity model revealed a
 pooled prevalence of 0.14 (95%CI 0.07 – 0.23) with heterogeneity among
 studies. Meta-regression revealed a significant association between
 prevalence and study location, the source population’s national human
 development index (HDI), and study quality. We found higher prevalence in
 European (0.22, 95%CI 0.14 – 0.30) and North American (0.15, 95% CI 0.05 –
 0.26) studies compared with Middle eastern and Asian studies (0.08, 95% CI
 0.01 – 0.18). However, within each region, populations from countries with
 higher HDI (p=0.03) and studies with higher quality (p=0.001) had lower
 prevalence. Calculated crude odds ratios showed that posterior circulation
 stroke (pooled OR 1.92, 95%CI 1.4-2.64; n=7 studies) and female sex
 (pooled OR 1.25, 95%CI 1.07-1.46; n=11 studies) had greater odds of
 headache associated with ischemic stroke. Conclusions: Taken together,
 these data suggest that headache is common at the onset of or shortly
 following ischemic stroke and may contribute to post-stroke morbidity.
 Better understanding of headache associated with ischemic stroke is needed
 to establish treatment guidelines and inform patient management.

title: Data from: Climatic change only stimulated growth for trees under weak competition in central boreal forests

description: 1. Global change ecologists have often used trees under weak competition
 (e.g., dominant/codominant trees) to examine relationships between
 climatic change and tree growth. Scaling up these results to a forest
 relies on the assumption that the climatic change-tree growth relationship
 is not affected by tree-level competition. 2. Using permanent sample plot
 data from the central Canadian boreal region where warming did not result
 in water deficit, we tested the above-mentioned assumption by looking at
 whether the relationship between climatic change and tree growth varied
 with tree-level competition, which was quantified using a modified Hegyi
 competition index. 3. We found that tree growth increased over time for
 trees under weak competition, but decreased for those under strong
 competition. The divergent temporal trends among trees under different
 levels of competition led to a non-significant change in growth for our
 study plots. Growth increased with regional warming, atmospheric [CO2] and
 water availability for trees under weak competition, but not for those
 under strong competition. 4. Synthesis. Our results suggest that upscaling
 the growth responses of dominant/codominant trees to climate change to a
 forest or a region can lead to biased estimates. Tree-level competition
 should be taken into account when expressing climatic change and tree
 growth relationships.

title: THE ROLE OF DOPAMINE DEFICIENCY IN PARKINSON'S DISEASE AND THE POTENTIAL BENEFITS OF THE KETOGENIC DIET

description: Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by the degeneration of dopaminergic neurons in the substantia nigra, resulting in dopamine deficiency and subsequent motor and non-motor impairments. Although the exact etiology of PD remains unclear, growing evidence implicates a combination of genetic susceptibility, environmental factors, mitochondrial dysfunction, oxidative stress, alpha-synuclein pathology, and dopamine-derived neurotoxicity, including the effects of 3,4-dihydroxyphenylacetaldehyde (DOPAL)(1-2).Dopamine plays a crucial role in the regulation of movement, motivation, cognition, and emotional processing. Its depletion disrupts basal ganglia circuitry, leading to the hallmark motor symptoms of Parkinson’s disease, as well as neuropsychiatric manifestations such as depression, apathy, and cognitive decline.(2-4) Despite significant advances in pharmacological therapies over the past decades, current treatments remain largely symptomatic and do not prevent disease progression.Recent research has increasingly focused on the role of dietary interventions as potential adjunctive therapeutic strategies.(5) Among these, the ketogenic diet has gained attention due to its ability to provide ketone bodies as an alternative energy source for the brain. Nutritional ketosis may improve mitochondrial efficiency, reduce oxidative stress and neuroinflammation, and potentially modulate alpha-synuclein aggregation and dopaminergic neuron vulnerability.This review summarizes current knowledge on the mechanisms underlying dopamine depletion in Parkinson’s disease and explores emerging evidence supporting the ketogenic diet as a complementary approach to conventional therapy.(7) While preliminary findings are encouraging, further well-designed clinical trials are required to establish the efficacy, safety, and long-term benefits of ketogenic dietary interventions in Parkinson’s disease.

title: Data from: Home-based TB contact investigation in Uganda: a household-randomized trial

description: Introduction: The World Health Organization(WHO) recommends household
 tuberculosis(TB) contact investigation in low-income countries, but most
 contacts do not complete evaluation. Methods: We performed a randomized
 trial of home-based, SMS-facilitated, household TB contact investigation
 in Kampala, Uganda. Community health workers(CHWs) visited homes of index
 patients with pulmonary TB to screen household contacts for TB. Entire
 households were randomly allocated to clinic(standard-of-care) or
 home(intervention) evaluation. In the intervention arm, CHWs offered
 adults HIV testing; collected sputum from symptomatic contacts and persons
 living with HIV(PLWH) if ≥5 years; and transported sputum for
 microbiologic testing. CHWs referred PLWH, children &lt;5, and anyone
 unable to complete sputum testing to clinic. Sputum-testing results and/or
 follow-up instructions were returned by automated SMS. The primary outcome
 was completion of TB evaluation within 14 days; secondary, TB and HIV
 diagnoses and treatments among screened contacts. Results: There were 471
 contacts of 190 index patients allocated to the intervention and 448
 contacts of 182 index patients allocated to the standard-of-care. CHWs
 identified 190/471(40%) intervention and 213/448(48%) standard-of-care
 contacts requiring TB evaluation. In the intervention arm, CHWs obtained
 sputum from 35/91(39%) sputum-eligible contacts and SMS were sent to
 95/190(50%) contacts. Completion of TB evaluation in intervention and
 standard-of-care arms at 14 days(14% vs 15%; difference -1%, 95%CI -9% to
 +7%, p=0.81) and yields of confirmed TB(1.5% vs 1.1%, p=0.62) and new
 HIV(2.0% vs. 1.8%, p=0.90) diagnoses were similar. Conclusions:
 Home-based, SMS-facilitated evaluation did not improve completion or yield
 of household TB contact investigation, likely due to challenges delivering
 the intervention components.

title: Data from: Sex difference in prevalence of depression after stroke

description: Objective: This study investigated the sex difference in prevalence of
 depression at 90 days after first-ever stroke. Methods: Patients with
 first-ever stroke (n = 786) were identified from the population-based
 Brain Attack Surveillance in Corpus Christi project (2011–2016).
 Poststroke depressive symptoms were assessed by the 8-itemPatient Health
 Questionnaire, and prestroke depression status (history and medication
 use) was self-reported. Logistic regression was used to examine the
 association between sex and depression after stroke, and effect
 modification by prestroke depression status, accounting for missing data.
 Results: Women were more likely to have a history of and be on medication
 for depression at the time of stroke than men (p &lt; 0.001).
 Prevalence of depression at 90 days was 28.2% for men (95% confidence
 interval [CI], 23.7%–32.8%) and 32.7% for women (95% CI, 27.8%–37.5%). The
 age-adjusted odds ratio (OR) of depression after stroke comparing women
 with men was 1.34 (95% CI, 0.97–1.85), and fully attenuated after
 adjustment for sociodemographic, stroke, and prestroke characteristics.
 Effect modification by prestroke depression status was present (p =
 0.038). Among participants on medication for depression at the time of
 stroke, women were significantly less likely to have depression at 90 days
 compared with men (OR, 0.39; 95% CI, 0.16–0.96); whereas significant sex
 differences were not noted among those with and without a depression
 history. Conclusion: The sex difference in prevalence of depression at 90
 days after first-ever stroke was not significant overall, but varied by
 prestroke depression status. Interventions to address and prevent
 poststroke depression are needed, particularly among those with prestroke
 depression but not undergoing treatment for depression at stroke onset.

title: Data from: Female rats release a trapped cagemate following shaping of the door opening response: Opening latency when the restrainer was baited with food, was empty, or contained a cagemate

description: Research on pro-social rat behaviour is growing within the fields of
 comparative psychology and social neuroscience. However, much work remains
 on mapping important variables influencing this behavior, and there is
 even disagreement on whether this behavior is empathetically motivated and
 correctly labelled pro-social, or whether the behavior is motivated by
 social contact. The present study used the helping behaviour paradigm
 where a rat can release a familiar cagemate from a restrainer. Prior to
 testing with a trapped cagemate, restrainer door opening was trained and
 baseline opening latencies when the restrainer was empty or baited with
 food were established. The findings show that the first-time release
 occurred sooner than in previous research and that rats used the trained
 response to release the trapped cagemate. Further, rats opened the
 restrainer door more often and with shorter latencies when the restrainer
 contained a cagemate than when the restrainer was empty, but less often
 and with longer latencies than when the restrainer contened food. Finally,
 we also found that the door opening persisted across levels of
 illumination.
