Severe leptospirosis in tropical and non-tropical areas: A comparison of two french, multicentre, retrospective cohorts.

Leptospirosis is an anthropozoonosis that occurs worldwide but is more common in tropical regions. Severe forms may require intensive care unit (ICU) admission. Whether the clinical patterns and outcomes differ between tropical and non-tropical regions with similar healthcare systems is unclear. Our objective here was to address this issue by comparing two cohorts of ICU patients with leptospirosis managed in mainland France and in the overseas French department of Réunion, respectively. We compared two retrospective cohorts of patients admitted to intensive care for severe leptospirosis, one from Reunion Island in the Indian Ocean (tropical climate) and the other from metropolitan France (temperate climate). Chi-square and Student's t tests were used for comparisons. After grouping the two cohorts, we also performed multiple correspondence analysis and hierarchical clustering to search for distinct clinical phenotypes. The Réunion and Metropolitan France cohorts comprised 128 and 160 patients respectively. Compared with the Réunion cohort, the metropolitan cohort had a higher mean age (42.5±14.1 vs. 51.4±16.5 years, p<0.001). Severity scores, length of stay and mortality did not differ between the two cohorts. Three phenotypes were identified: hepato-renal leptospirosis (54.5%) characterized by significant hepatic, renal and coagulation failure, with a mortality of 8.3%; moderately severe leptospirosis (38.5%) with less severe organ failure and the lowest mortality rate (1.8%); and very severe leptospirosis (7%) manifested by neurological, respiratory and cardiovascular failure, with a mortality of 30%. The outcomes of severe leptospirosis requiring ICU admission did not differ between tropical and temperate regions with similar healthcare access, practices, and resources, despite some differences in patient characteristics. The identification of three different clinical phenotypes may assist in the early diagnosis and management of severe leptospirosis.

Return Migration and Fertility: French Overseas Emigrants, Returnees, and Nonmigrants at Origin and Destination.

Although growing research has emphasized the critical importance of studying returns for understanding various aspects of migration processes, knowledge regarding return migrants' fertility behaviors remains limited. This study addresses this knowledge gap by comparing rates of first births and completed fertility among three groups: nonmigrants (at origin), migrants, and return migrants. Using extensive data collected both in the home regions and at destination, we analyze female migration from Martinique, Guadeloupe, French Guiana, and Réunion Island to metropolitan France (European France). We find intermediate fertility behaviors for return migrants relative to nonmigrants and migrants: on average, completed fertility levels are lower among return migrants than nonmigrants but slightly higher among return migrants than migrants. Some of these differences can be attributed to selection into migration and return, although significant gaps persist among women with similar socioeconomic characteristics. Our findings highlight three key observations. First, when migrants return before beginning childbearing, their transition to motherhood closely resembles that of nonmigrants with similar characteristics. Second, the lower fertility rates among prospective return migrants indicate an anticipation of disruption effects. Finally, reduced fertility while residing in metropolitan France translates into lower completed fertility rates for return migrants.

Spatial wage disparities and human capital externalities in France

AbstractWe re‐examine the respective role of local density and local concentration of human capital in the agglomeration gains for about 750,00 individuals working in 304 commuting zones of metropolitan France over the period 2009–2015. Agglomeration gains are mostly driven by human capital effects over this period. Also, because it absorbs dynamic learning effects, the use of worker fixed effects to address spatial sorting of individuals may underestimate, by about two third, the wage premium with respect to local concentration of human capital over a midterm period. Finally, wage gaps stem more from differences in human capital in the private sector than in the public sector. We do not find evidence of a multiplier effect of public employment on local human capital externalities in the private sector.

SARS-CoV-2 infection prevalence and associated factors among primary healthcare workers in France after the third COVID-19 wave

Data on the SARS-CoV-2 infection among primary health care workers (PHCWs) are scarce but essential to reflect on policy regarding prevention and control measures. We assessed the prevalence of PHCWs who have been infected by SARS-CoV-2 in comparison with modeling from the general population in metropolitan France, and associated factors. A cross-sectional study was conducted among general practitioners (GPs), pediatricians, dental and pharmacy workers in primary care between May and August 2021. Participants volunteered to provide a dried-blood spot for SARS-CoV-2 antibody assessment and completed a questionnaire. The primary outcome was defined as the detection of infection-induced antibodies (anti-nucleocapsid IgG, and for non-vaccinees: anti-Spike IgG and neutralizing antibodies) or previous self-reported infection (positive RT-qPCR or antigenic test, or positive ELISA test before vaccination). Estimates were adjusted using weights for representativeness and compared with prediction from the general population. Poisson regressions were used to quantify associated factors. The analysis included 1612 PHCWs. Weighted prevalences were: 31.7% (95% CI 27.5–36.0) for GPs, 28.7% (95% CI 24.4–33.0) for pediatricians, 25.2% (95% CI 20.6–31.0) for dentists, and 25.5% (95% CI 18.2–34.0) for pharmacists. Estimates were compatible with model predictions for the general population. PHCWs more likely to be infected were: GPs compared to pharmacist assistants (adjusted prevalence ratio [aPR] = 2.26; CI 95% 1.01–5.07), those living in Île-de-France (aPR = 1.53; CI 95% 1.14–2.05), South-East (aPR = 1.57; CI 95% 1.19–2.08), North-East (aPR = 1.81; CI 95% 1.38–2.37), and those having an unprotected contact with a COVID-19 case within the household (aPR = 1.48; CI 95% 1.22–1.80). Occupational factors were not associated with infection. In conclusion, the risk of SARS-CoV-2 exposure for PHCWs was more likely to have occurred in the community rather than at their workplace.

Spatial Accessibility to Primary Care in Metropolitan France: Results Using the SCALE Spatial Accessibility Index for All Regions.

Accessibility to care is a major public health issue. Various tools to assess it are available, but they do not solve the problem of scale. Moreover, accessibility is a multidimensional concept that is not taken into account with current tools. The SCALE index aims to overcome these two limitations by proposing a synthetic measure on a more precise scale than the administrative unit or the sub-municipal scale. Under the assumption of access to care facilities for all and access to the nearest facilities, the potential accessibility distance was calculated for each couple (residential area, accessible facilities). This was defined as the average distance by road that the population has to travel to access care. To take the availability of resources into account, these distances were weighted by the theoretical pressure on the facilities. The SCALE index was then calculated using a linear combination of the distances of potential accessibility to care facilities It highlights differences in accessibility at the national and regional scale. Using this index, it was possible to provide maps for all French regions and the major cities in a story-map. The major conurbation around Paris and the main urban centers has high accessibility. Low accessibility forms a "Y" shape. In conclusion, the SCALE index measures accessibility at the scale of a small geographic unit taking the proximity and the availability of health professionals into account. It is also possible to take into account the diversity of accessibility in a given territory.

Characterization of periods of high and low hydrological activity in the Loire River, France, between the 14th and mid-19th centuries

The Loire River watershed accounts for a fifth of metropolitan France. Nevertheless, knowledge of past floods of the Loire River and its tributaries is still very limited. This study aimed to carry out an unprecedented census of floods in the Loire River, during the Little Ice Age (LIA), from the 14th century to the mid-19th century, in order to detect periods of high and low hydrological activity. The abundant historical archives in the cities of Nevers and Decize, as well as other archives consulted, enabled us to record 303 flood events, including 220 in the study area between Digoin and Nevers in Burgundy. This census is heterogeneous over the centuries, with the majority of newly recorded flood events taking place during the 14th and 15th centuries, first half of the 16th century, and 18th and 19th centuries. The use of two types of flood indexes enabled this study to overcome the documentary bias, and detect several decadal periods of high or low hydrological activity during the LIA in the Loire River. Almost all these periods can be found on other rivers in both France and Europe, the Loire River being exposed to the confluence of several climatic influences, as confirmed by comparisons with the North Atlantic Oscillation (NAO), Grand Solar minima and temperature fluctuations. Nevertheless, the coldest periods of the LIA, coupled with negative NAO positions, correspond to periods of high hydrological activity in the Loire River. The study of flood seasonality also reveals a high degree of variability during the LIA, with a higher proportion of flood events occurring in summer and autumn compared with the current seasonal pattern.

Emotional experience of mothers facing visitor restrictions in the maternity wards during the COVID-19 pandemic: A qualitative study

ObjectivesUsing a qualitative method, this study explored the experiences and opinions of mothers facing visitor restrictions in maternity wards during the COVID-19 pandemic in Europe. Population and methodsA total of 16 women between the ages of 29 and 38 years were recruited. They gave birth between April 2020 and July 2022 in metropolitan France or the Netherlands. Each participant had an individual and semi-directional telephonic interview which was transcribed and subjected to thematic content analysis. ResultsVisitor restrictions in maternity wards were a source of great apprehension for participants, which is the first theme of our thematic analysis. The unknown, changes in restrictions and mentions of other mothers who had experienced such restrictions were often sources of fear, anxiety and a heavy mental load for these participants. The second theme was the yearning and related to the lack of emotional and physical support that mothers felt when their family and friends were not allowed in the maternity ward; this theme also highlighted the central place given to the new-born's siblings in this ward. The third theme was the traumatic experience of mothers who have experienced the restriction of their partner. These results underline the need for participants to be accompanied by their partners throughout their stay in the maternity ward. Finally, tranquillity was the last theme and was related to the absence of family and friends during postpartum care, something that participants had differing opinions about but that most agreed would have given them a better first postpartum experience in the maternity ward. DiscussionWhether viewed as positive or negative, visitor restrictions have a significant impact on how mothers experience their childbirth and stay in a maternity ward. ConclusionsIf a new wave of the pandemic were to occur, these results would encourage policy makers to rethink visitor restrictions in maternity wards and consider the need for every mother to be surrounded there by the people of her choice.

TEMPORARY REMOVAL: Mortalité maternelle en France, 2016–2018, fréquence, causes et profil des femmes

Objective: To describe, for the 2016-2018 period, the frequency, causes and risk factors of maternal deaths in France.Method: Data from the National Confidential Enquiry into Maternal Deaths for 2016-2018Results: For 2016-2018, 272 maternal deaths occurred in France, i.e a maternal mortality ratio of 11,8 per 100,000 live births (95% CI 10,4-13,3), and 8.5 (IC 95 % 7,4-9,8) for maternal mortality up to 42 days. Compared to women aged 20-24, the risk of maternal death is multiplied by 2.6 for women aged 35-39, by 5 for women aged 40 and over. Obese women are twice as frequent among maternal deaths (26%) than in the general population of parturients (11%). There are territorial disparities -the maternal mortality ratio in the French overseas departments is 2 times higher than in metropolitan France (significant difference but smaller than in 2013-2015)-, and social disparities -the mortality of migrant women remains higher than that of women born in France, particularly for women born in sub-Saharan Africa whose risk is 3 times higher than that native women. One in three women who died (34%) had socio-economic vulnerability versus 22% in the overall population of parturients.Among causes of maternal deaths, the predominant role of psychiatric conditions (mostly suicides) is confirmed for the period 2016-2018, leading cause of maternal mortality considered up to 1 year (17%), MMR of 1.9 /100,000 NV. i.e. approximately one death from psychiatric causes every 3 weeks. Cardiovascular diseases are the second leading cause of maternal mortality up to one year (14%) and the leading cause up to 42 days (16%), with 1.3 deaths per 100,000 NV. Amniotic embolism ranks as the third cause (8%) (2nd cause, 11%, for MM limited to 42 days), i.e. MMR of 0.9 per 100,000 NV. After a regular decline over the last decade, maternal mortality from obstetric hemorrhage is at a stable level compared to the previous triennium 2013-2015, MMR of 0.9/100,000 NV, i.e 5th cause of MM up to one year (7%) and 4th cause of MM up to 42 days.Conclusion: The overall national maternal mortality ratio does not show a downward trend, even with constant surveillance method. Territorial inequalities persist but change in their magnitude and in the regions concerned. The profile of the causes of maternal mortality up to one year of the pregnancy end shows the leading role of suicides and cardiovascular diseases, which illustrates that the health of pregnant women or those who have recently given birth is not limited to the obstetric domain, and highlights the importance of multidisciplinarity in the management and organization of care for women in this period

Pneumocystose

AbstractThe Pneumocystis genus includes some species belonging to Ascomycota phylum. These micromycetes are atypical because they are presently uncultivable, resistant to amphotericin B and azoles but sensitive to sulfonamides and echinocandins. They have a strong pulmonary tropism and are airborne transmitted between host mammals of the same species. Pneumocystis jirovecii (P. jirovecii) is the species infecting humans. It is responsible for severe pneumonia in patients infected with human immunodeficiency virus (HIV). Pneumocystis pneumonia (PCP) remains the most common AIDS defining opportunistic infection in metropolitan France. However, PCP is currently more commonly observed in immunocompromised patients not infected with HIV The symptoms of PCP include the triad, fever, dyspnea and dry cough associated with ground-glass pictures at the chest CT-scan in relation to bilateral alveolar-interstitial pneumonia.The biological diagnosis of PCP is based on the detection of P. jirovecii by microscopy and PCR in lung samples, with broncho-alveolar lavage fluid remaining the reference sample. β-1,3-D-glucan detection in serum is an additional useful diagnostic tool. The sulfamethoxazole-trimethoprim combination is the first-line treatment while pentamidine, atovaquone, dapsone, and echinocandins represent second-line treatments.

Groundwater level reconstruction using long-term climate reanalysis data and deep neural networks

Study regionNorthern Metropolitan France. Study focusAssessing long-term changes in groundwater is crucial for understanding the impacts of climate change on aquifers and for managing water resources.However, long-term groundwater level (GWL) records are often scarce, limiting the understanding of historical trends and variability. In this paper, we present a deep learning approach to reconstruct GWLs up to several decades back in time using recurrent-based neural networks with wavelet pre-processing and climate reanalysis data as inputs. GWLs are reconstructed using two different reanalysis datasets with distinct spatial resolutions (ERA5: 0.25° x 0.25° & ERA20C: 1° x 1°) and monthly time resolution, and the performance of the simulations were evaluated. New insightsLong term GWL timeseries are now available for northern France, corresponding to extended versions of observational timeseries back to early 20th century. All three types of piezometric behaviours could be reconstructed reliably and consistently capture the multi-decadal variability even at coarser resolutions, which is crucial for understanding long-term hydroclimatic trends and cycles. GWLs'multidecadal variability was consistent with the Atlantic multidecadal oscillation. From a synthetic experiment involving a modified long-term observational time series, we highlighted the need for longer training datasets for some low-frequency signals. Nevertheless, our study demonstrated the potential of using DL models together with reanalysis data to extend GWL observations and improve our understanding of groundwater variability and climate interactions.

La traduction — facteur et/ou vecteur d’identité. Une lecture des « Salaziennes » d’Auguste Lacaussade

How can we study the making of a poet-translator’s identity, of one who was born in a colony and decided to settle in Metropolitan France, especially when his ethnic and social backgrounds set him apart? Individual or literary identity is built on a person’s relation to others, as established by Paul Ricoeur’s and Édouard Glissant’s works. This is how Lacaussade tried to approach the matter; while being a budding poet, he turned to foreign, and in particular, anglophone poets. Beyond mere imitation, translation facilitates creative writing, so being acknowledged as a creator in his own right helped him.

Efficient pathway for men fertility preservation in testicular cancer or lymphoma: a cross-sectional study of national 2018 data

BackgroundIn 15–49 years-old men, the main cancers are testicular cancer (TC) and lymphomas (L): freezing of ejaculated sperm is primarily used for male fertility preservation (FP) before cancer treatment.Our objective was to analyze the French FP rate in 15–49 years-old men diagnosed with TC or L in 2018.We designed a national descriptive cross-sectional study of sperm banking rate in men with a diagnosis of TC, Hodgkin L (HL) or non-Hodgkin L (NHL).From the French National Cancer Institute (INCa) 2018 data, we extracted the estimated incidence of TC and L in metropolitan France. From the 2018 activity report of CECOS network (Centers for Study and Banking of Eggs and Sperm), we extracted the number of men with TC or L who banked ejaculated sperm. We estimated the proportion of 15–49 years-old men diagnosed with TC or L who banked sperm.ResultsAmong 15–49 years-old men, INCa estimated 38,048 new cancer diagnoses in metropolitan France in 2018: 2,630 TC and 3,913 L (943 HL and 2,970 NHL). The CECOS network provided data from 26/27 metropolitan centers (96% response rate): 1,079 sperm banking for men with TC, 375 for HL and 211 for NHL.We estimated that the 2018 sperm banking rate in France was 41% for TC, 40% for HL, and 7% for NHL.ConclusionsTo our knowledge, our paper is the first cross-sectional study with multicenter and national data analyzing FP rate in cancer men: it suggests an efficient pathway for men to FP before cancer treatment, compared to previously published studies. Although sperm banking rate in 15–49 years-old men could definitely be improved, further studies should evaluate the information given to patients before gonadotoxic treatments, the factors associated with the absence of sperm banking and whether this lack of referral induces a loss of chance for these men.

Archeohandi: protocol for a national disabilities database in archaeology in France

The archaeology of disability is a relatively recent and little-known approach in France. While the study of palaeopathology now goes hand in hand with funerary archaeology and osteoarchaeology, the French study of disabilities and disabling pathologies remains marginal and unevenly treated, depending on location, chronology and researcher’s interest. This paper focuses on highlighting the compatibility between this new research area, the obligations of osteoarchaeology, and the benefits of developing a national, diachronic, and interdisciplinary study. A database is designed within an interpretive, consensual framework, that can be adapted to overcome limitations and promote open-minded research on the care of the disabled in their own communities. A preliminary category selection of disabling pathologies has been made. These are trepanation, completely edentulous and/or compensating denture, neuronal impairment, severe scoliosis, Paget's disease, Diffuse Idiopathic Skeletal Hyperostosis (DISH), rickets, dwarfism, infectious diseases, unreduced fracture, amputation, severe degenerative disease and others. This list has been critically reviewed by experts in the field; it will evolve in a somewhat Darwinian fashion. Our database is hosted on the Huma-Num platform, with a management interface and quick access based on multiple tabs. The data includes information about archaeological operations, subjects, and pathologies; it is complemented by pictorial data stored on the Nakala platform. The development involved creating a prototype using HTML, CSS, JavaScript, SQL, and PHP, with features to display, add, modify, and delete operations and subjects. Enhancements have been made, including search optimization, charts, and the ability to export data in CSV format. The database, whose administrative interface can be accessed at archeohandi.huma-num.fr, contains so far 211 existing operations with a total of 1232 registered subjects spread throughout metropolitan France. These initial data reveal numerous research perspectives in osteoarchaeology that can be combined with other research topics, such as virtual reality.

Spatiotemporal and Individual Patterns of Domestic Cat (Felis catus) Hunting Behaviour in France.

Domestic cats (Felis catus), one of the most popular pets, are widespread worldwide. This medium-sized carnivore has well-known negative effects on biodiversity, but there is still a need to better understand the approximate causes of their predation. Based on a citizen science project, we assessed the role of spatiotemporal (i.e., latitude, longitude, and seasons), climatic (i.e., rainfall), anthropogenic (i.e., human footprint, HFI), and individual (i.e., sex and age) variables on the number of preys returned home by cats in metropolitan France. Over the 5048 cats monitored between 2015 and 2022, prey from 12 different classes (n = 36,568) were returned home: 68% mammals, 21% birds, and 8% squamates. Shrews brought home by cats peaked during summer, while rodents were recorded during summer-autumn. Birds brought home by cats peaked in spring-summer and in autumn, and lizards peaked in spring and in late summer. Lower HFI was associated with more voles and mice brought home, and the opposite trend was observed for lizards and birds. Younger cats were more prone to bring home shrews, birds, and reptiles. Although environmental factors play a minor role in prey brought home by cats, some geographical characteristics of prey species distribution partly explains the hunting behaviour of cats.

The Skills of Citizenship

Abstract This article analyzes the history of adult vocational training (AVT) programs for Algerian migrants, funded by the French state, between the end of World War II in 1945 and the aftermath of Algerian independence in 1962. These programs responded to the postwar expansion of citizenship and rights of indigenous Algerians, including rights to migrate and to take jobs in metropolitan France. Across changing governments and diverse ministries, French officials were convinced that vocational training was necessary for indigenous Algerians to find stable employment, to mitigate the supposed risks of migration, and to enable migrants to transform themselves into an idealized version of the French citizen. The widespread adoption of AVT for Algerian migrants calls into question the pervasive image of the unskilled, interchangeable migrant. At the same time, the shortcomings of AVT programs shed light on how migrants frequently contributed to postwar economic expansion and economic modernization while enjoying the fruits of economic growth only meagerly and on an individual basis. More broadly, this study reveals the importance of skill, industry, and labor in French postwar conceptions of (social) citizenship.

Major field margin vegetation types in France and their relationships with climate, agricultural landscapes and management intensity

ABSTRACT Arable field margins are an important semi-natural habitat providing multiple functions in agroecosystems. Despite three decades of research, analyses of species assemblage and functional traits are lacking. Leveraging a national monitoring network in metropolitan France, we aim to provide a comprehensive taxonomic and functional synthesis of field margin flora, outline main field margin types and explore their associations with management practices, climate, and agricultural landscapes. We analysed data from 532 field margins surveyed between 2013 and 2017, using both uni- and multivariate analyses. Field margins exhibited great diversity with 711 distinct taxa (12% of all flora in mainland France) at the national scale and an average of 16 species per 10 m2 locally. While field margins contained few species of conservation value, they offered a refuge for many declining species as well as rare arable weed species. We identified seven main field margin types, each linked to distinct conditions of climate, soil, landscape and agricultural practices. Mediterranean field margins notably differed from all others. In the main cluster, vineyard margins also stood out as distinct from annual crop margins. Additionally, field margins in landscapes with a high proportion of grassland differed from those within intensively cultivated field crop plains in conventional agriculture. Overall, our study highlights the high botanical diversity of field margins and their interest for plant conservation in agricultural landscapes. Promoting the installation and/or maintenance of field margins through agri-environmental schemes should thus favour biodiversity conservation and associated ecosystem provision.

Prevalence of past-year major depressive episode among young adults between 2005 and 2021: Results from four national representative surveys in France

BackgroundThe objectives are to examine time trends in the prevalence of past year major depressive episode (MDE) among young adults, and to identify differences by occupational status comparing students, those employed, and those who are not in employment, education or training (NEET). MethodsData were drawn from the Health Barometer survey, a cross-sectional computer-assisted telephone interview survey on a national representative sample of residents of metropolitan France and conducted approximately every 5 years. The surveys relied on the Composite International Diagnostic Interview-Short Form to determine the presence of DSM-IV past-year major depressive episode. Data from the 2005, 2010, 2017, and 2021 surveys were pooled and respondents aged 18 to 25 were selected (n = 7556) and categorized based on their occupational status: students, those employed, and NEET. ResultsOverall, significant differences in the prevalence of MDE was observed by occupational status: NEET had the highest rate (18.5 %) followed by students (14.3 %) and those employed (11.0 %). The prevalence of MDE among young adults was 10.1 % in 2005, 9.7 % in 2010 and 11.3 % in 2017, reflecting a stable prevalence between 2005 and 2017. The prevalence then nearly doubled in 2021, with 20.9 % of MDE, with a significant increase of 9.6 points between 2017 and 2021. LimitationsNo assessment of lifetime psychopathology. ConclusionsThe prevalence of major depression among young adults significantly increased between 2005 and 2021, those at greatest risk are females and those not in employment, education or training. The contribution of pandemic-related factors may be elucidated in future national health surveys.

Analyse de l'hypertension en France : pour une analyse intersectionnelle de la cascade de soins

In metropolitan France, estimates suggest that more than one in three adults has hypertension. Low-cost treatments are available, yet fewer than one in four hypertensive adults has a controlled level of hypertension below 140/90 mmHg. This rate is higher in other high-income countries such as Canada (65%) or Germany (52%). Using a ‘cascade of care’ model, that decomposes the hypertension care continuum in awareness, treatment, and control, provides a better understanding of the origins of poor control. Furthermore, the theoretical framework of intersectionality, which simultaneously considers social positions of gender, class, and ethno-racial origin, could be used to understand the complexity of the social inequalities observed in hypertension-related outcomes. In this article we conducted a critical review of the international literature to identify new lines of analyses that could be applied to examine complex inequalities in France.

Farmland biodiversity benefits from small woody features

Although positive effects on biodiversity of woody features in agricultural landscapes are widely recognized, questions remain as to which landscape context to prioritize their implementation and in what proportion. To investigate the response of farmland biodiversity to small woody features (SWF) density in different landscape compositions (cropland, grassland, mixed), we analyzed fine-resolution data from standardized monitoring schemes on 111 birds, 22 bats, and 25 bush cricket's species, at national scale (relying on 3772, 834 and 727 monitoring points) over the period 2015–2019, in metropolitan France. We used Generalized Additive Mixed Models to analyze population and community responses, through different metrics (abundance, species diversity, and functional composition). We found a positive response exhibited by the three taxa to SWF, more especially in cropland where the SWF density is the lowest relative to grassland and mixed landscapes. Also, our results suggested a non-linear response common to the three taxa, with an increased benefit up to at least 6 % of SWF density in cropland, and beyond for most of the metrics but to a lesser extent (e.g., maximum abundance reached at 7–12 % SWF). We note, however, that some species among farmland bird specialists are negatively impacted by SWF. Overall, we emphasize the benefits to promote woody features in agricultural landscapes, notably in cropland, to support biodiversity and its associated ecosystem functions. Our study provides crucial empirical evidence to the recommendations from previous studies and the relevance of the EU Biodiversity Strategy for 2030 to dedicate at least 10 % of farmland to high-diversity landscape features.
