Tensions typically emerge between farmers who advocate rabbit reduction and hunters who wish healthy rabbit populations for shooting. In this study, we used in-depth interviews and small group discussions with farmers, hunters and representatives of the governmental environmental agencies to assess their positions in this conflict. Our results showed that this conflict is characterised by tensions between and within groups, and influenced by leadership, distrust and past decision-making issues, and differences in beliefs among groups. Positions of farmers and hunters are also relatively rigid, which may make difficult their engagement in collaborative processes. To be effective, such processes need that local leaders are empowered and likely also that external neutral mediators are involved., Our research was conducted in two study areas: Campiña Sur de Córdoba (CSC) in Andalusia, southern Spain, and Alt Camp de Tarragona (ACT) in Catalunya, northern Spain. CSC and ACT comprise 11 and 23 municipalities, respectively, the former being larger than the latter (1100 km2 vs. 538 Km2) and including more inhabitants (105,000 vs. 44,000 inhabitants). These areas were selected due to similarities in the global context regarding rabbit damage to crops. The presence of vineyards is notable in both areas and there is significant rabbit damage to vineyards in both., In this study, we used qualitative techniques to understand perspective and views of the main stakeholders involved: farmers, hunters, and people working for governmental agencies in charge of wildlife management. Participants were selected using contact information provided by key informants in both study areas (snow-ball sampling). The total number of participants was 55. We used personal interviews to gather the opinion of key informants; i.e. managers in relevant farming associations, game managers and people working for environmental agencies. To assess the opinion of “regular” hunters and farmers, we used small discussion groups with three or four participants. To avoid the risk that an “opinion leader” may dominate the conversation in a discussion group, the moderator managed this potential limitation through promoting the participation of the most reticent people., Interviews and small discussion groups were conducted between 15th October and 16th December 2015. We stopped data collection when we observed that no new key themes emerged with further data. Both the interviews and the small discussion groups were conducted in such a way that a space was created for the open expression of the positions and criteria of the interviewees, that is, in a non-directive and conversational manner. The interviews and small discussion groups were conducted following a script of issues to be addressed, but it was adapted to the characteristics of the participants and the own development of the interviews and discussion groups. The script addressed participants’ perceptions about rabbit populations and rabbit damage to crops both in the recent past and when the survey was done and their perceptions and opinions about rabbit management conducted in the study area. In addition, it also dealt with the relationships between stakeholders involved in the problems caused by rabbit damage to crops as well as with participants’ attitudes towards other collectives or groups. Participants were guaranteed the mutual confidentiality and anonymity of the opinions expressed. Their express consent was obtained for participation in this study, which was done in compliance with both the Spanish and European legislations in terms of data privacy (Spanish Organic Law 3/2018; European Regulation 2016/679). Interview duration ranged between 15 and 120 minutes, while groups ranged between 45 and 150 minutes. Both were digitally recorded and transcribed. Data from interviews and small groups were analyzed jointly since both addressed the same key issues and had the same informative and opinion nature. Data analysis consisted of reading iteratively each text to identify main ideas and topics, pursuing an understanding and sociological interpretation of the data, checking interpretations among co-authors to create added awareness of certain dimensions in the data, and thus to identify properly the main themes., In order to ensure full protection of participants’ privacy and compliance with Spanish law of data protection (i.e. Royal Decree-Law 5/2018, of July 27th, on urgent measures for adaptation of Spanish Law to European Union regulations on data privacy), raw data is not made publicly available. Instead, a summary of raw data is shown and the information is anonymized and those parts that could give rise to the recognition of any of the participants have been eliminated, thus respecting confidentiality, [ES] En las zonas agrícolas españolas, el conejo europeo puede causar daños considerables a los cultivos. Las tensiones suelen surgir entre los agricultores, que abogan por la reducción de la población de conejos, y los cazadores, que desean disponer de un número elevado de conejos para cazar. En este estudio utilizamos entrevistas en profundidad y grupos de discusión reducidos con agricultores, cazadores y representantes de la administración ambiental y agrícola para evaluar sus posiciones en este conflicto. Nuestros resultados muestran que este conflicto se caracteriza por tensiones tanto inter como intragrupales, y está influenciado por el liderazgo, la desconfianza y los problemas de toma de decisiones pasadas, y las diferencias de creencias entre los distintos colectivos. Los posicionamientos de los agricultores y cazadores también son relativamente rígidos, lo que puede dificultar su participación en procesos de colaboración. Para ser efectivos, tales procesos necesitan que los líderes locales estén empoderados y probablemente también que participen mediadores externos neutrales., Nuestra investigación se llevó a cabo en dos áreas de estudio: Campiña Sur de Córdoba (CSC) en Andalucía, sur de España, y Alt Camp de Tarragona (ACT) en Catalunya, norte de España. CSC y ACT comprenden 11 y 23 municipios, respectivamente, siendo el primero más grande que el segundo (1100 km2 frente a 538 km2) e incluyendo más habitantes (105.000 frente a 44.000 habitantes). Estas áreas fueron seleccionadas debido a similitudes en el contexto global con respecto al daño de los conejos a los cultivos. La presencia de viñedos es notable en ambas zonas y existe igualmente un importante daño por conejos en los viñedos en ambas comarcas., En este estudio, utilizamos técnicas cualitativas para comprender la perspectiva y los puntos de vista de los principales actores involucrados: agricultores, cazadores y personas que trabajan en la administración vinculadas a la gestión de la vida silvestre. Los participantes fueron seleccionados utilizando la información de contacto proporcionada por informantes clave en ambas áreas de estudio (muestreo de bola de nieve). El número total de participantes fue de 55. Utilizamos entrevistas personales para recabar la opinión de informantes clave; es decir, representantes de organizaciones agrarias relevantes, gerentes de cotos de caza y personas que trabajan en la administración. Para evaluar la opinión de los cazadores y agricultores, utilizamos pequeños grupos de discusión con tres o cuatro participantes. Para evitar el riesgo de que un “líder de opinión” pueda dominar la conversación en un grupo de discusión, el moderador manejó esta potencial limitación promoviendo la participación de las personas más reticentes., El conjunto de entrevistas y grupos de discusión se desarrolló entre el 15 de octubre y el 16 de diciembre de 2015. La recopilación de datos se detuvo cuando observamos que no surgían nuevos temas clave o relevantes para el objeto de estudio. Tanto las entrevistas como los pequeños grupos de discusión se realizaron de tal manera que se creó un espacio para la expresión abierta de las posiciones y criterios de los entrevistados, es decir, de manera no directiva y conversacional. Las entrevistas y los pequeños grupos de discusión se realizaron siguiendo un guion de temas a tratar, pero se adaptó a las características de los participantes y al propio desarrollo de las entrevistas y grupos. El guion abordó las percepciones de los participantes sobre las poblaciones de conejos y el daño producido a los cultivos, tanto en el pasado reciente como cuando se realizó la encuesta, y sus percepciones y opiniones sobre el manejo de conejos realizado en las áreas de estudio. Además, también se trataron las relaciones entre los colectivos involucrados en los problemas causados por el daño de los conejos a los cultivos, así como las actitudes de los participantes hacia otros grupos. Se garantizó a los participantes la confidencialidad y el anonimato de las opiniones expresadas. Se obtuvo su consentimiento expreso para participar en este estudio, el cual se realizó en cumplimiento de la legislación tanto española como europea en materia de privacidad de datos (Ley Orgánica 3/2018; Reglamento Europeo 2016/679). La duración de las entrevistas osciló entre los 15 y los 120 minutos, mientras que los grupos variaron entre 45 y 150 minutos. Ambos fueron grabados y transcritos digitalmente. Los datos de las entrevistas y grupos se analizaron de forma conjunta, ya que ambos abordaron los mismos temas clave y tenían el mismo carácter informativo y de opinión. El análisis de datos consistió en la lectura iterativa de cada texto para identificar las ideas y temas principales, buscando una comprensión e interpretación sociológica de los datos, verificando las interpretaciones entre los coautores para crear una mayor conciencia de ciertas dimensiones en los datos y así identificar adecuadamente los temas principales., Con el fin de garantizar la plena protección de la privacidad de los participantes y el cumplimiento de la ley española de protección de datos (es decir, el Real Decreto-ley 5/2018, de 27 de julio, de medidas urgentes para la adaptación de la legislación española a la normativa de la Unión Europea sobre privacidad de datos), los datos brutos no se ponen a disposición del público. En cambio, se muestra un resumen de los datos brutos y se anonimiza la información y se eliminan aquellas partes que pudieran dar lugar al reconocimiento de alguno de los participantes, respetando así la confidencialidad., We acknowledge financial support from the Spanish Science Ministry (MINECO) through project CGL2013-43197-R; and from Spanish Council for Scientific Research (CSIC) through PII-201810I026., La información contenida en el fichero de datos se estructura de la siguiente forma: Comarca Alt Camp (Tarragona) -Entrevistas y grupos de discusión cazadores, agricultores y administración Comarca Campiña Sur (Córdoba) -Entrevistas y grupos de discusión cazadores, agricultores y administración, Con objeto de asegurar la completa protección de la privacidad de los participantes en las entrevistas y cumplir con la legislación española de protección de datos (p.ej.

UNDERLAYING DATA FOR PAPER "AUTONOMOUS SHALLOW FLOW RUNOFF DETECTOR FOR HILLSLOPE HYDROLOGICAL STUDIES", DATOS CORRESPONDIENTES AL ARTÍCULO "AUTONOMOUS SHALLOW FLOW RUNOFF DETECTOR FOR HILLSLOPE HYDROLOGICAL STUDIES"

Data corresponding to the calibration and validation of overland flow detectors presented in in paper "Autonomous shallow flow runoff detector for hillslope hydrological studies".-- Datos de calibración y validación de detectores de escorrentía presentados en el artículo "Autonomous shallow flow runoff detector for hillslope hydrological studies"., This is the underlaying data for the manuscript which describes the development, calibration and validation of an autonomous overland flow detector (OFD) for the measurement and recording of shallow runoff depth at varying recording intervals based on measurement of runoff water electrical conductivity (EC). Using electronic components easily available and of moderate cost, approximately367€ per unit, the proposed device can operate for a broad range of surface overland flow with EC from 0 to 435 µS cm-1 with a regular charge using a small built-in cell panel. It was originally intended for use in experiments related to runoff connectivity and efficiency of vegetated buffer strips at hillslope scale. Results show how, once calibrated for the expected range of runoff EC, the proposed device can provide reliable and replicable measurements among different units with an average root mean square error of 3mm. When deployed in the validation test under rainfall simulation with water of high EC (435 µS cm-1)it allowed the determination of the evolution of the change in runoff starting time and the duration of the hydrograph after the end of rainfall in individual points as a function of slope length. In this test the differences in depth among OFD was not significant, since being lower than 4 mm overlaps with the average measurement error among units. This result highlights the need for careful interpretation of the measured depth in relation to the equipment measurement error in spatial variability of shallow flow. Further improvements will concentrate on remote communication for downloading data via a cell phone network, and additional ruggedness and autonomy for long-term deployment in the field under very cloudy conditions., AGL2015-65036-C3-1-R (Spanish Government), Peer reviewed

Variables Description Ring Number of the ring of the GPS-tracked burrowing owl DateTimeUTC Date and time in dd/mm/yyyy hh:mm:ss (UTC) Latitude Latitude in decimal degrees Longitude Longitude in decimal degrees Altitude Altitude (in meters) taken from the GPS data logger Code Day or Night Airam Rodríguez (airamrguez@ebd.csic.es; airamrguez@gmail.com), José Hernán Sarasola (sarasola@exactas.unlpam.edu.ar), 18 burrowing owls were tagged with GPS-data loggers (Catnip Technologies, USA) on Teflon harnesses as back mounts. The original case of GPS data-loggers was removed, and batteries were replaced by smaller rechargeable ones (100-150 mAh). Loggers were put in a heat-shrink tube for waterproofing. The final size was 25 × 43 × 10 mm and weights ranged between 12.8 and 16.4 g. GPS data-loggers were programmed with two settings: 1) loggers recording a position per minute until battery flat; and 2) loggers recording a position per minute during the night, while switched off during daylight hours (from 11:00 to 20:00 or from 8:00 to 17:00 UTC). Loggers started to log data the night following capture. All data loggers were operative at the moment of recapture or recovery, but two of them failed to provide useful data, Peer reviewed

Unveiling the drivers of local dung beetle species richness in the Neotropics, Journal of Biogeography 2021. See the original paper for more details., This database is based on a survey of published literature on dung beetle communities to extract information on species richness, abundance, type of bait, type of habitat, and sampling effort (as hours/pitfall) for different localities, discarding sites with low sampling effort. We used environmental variables to account for six possible explanations of species richness gradients: productivity, water–energy, ambient energy, habitat heterogeneity, resource heterogeneity, and seasonality, as well as spatial data to account for other geographically-structured phenomena. In total the database contains data for 300 localities., This work was supported by the projects ‘Predicting diversity variations across scales through process-based models linking community ecology and biogeography’ (CNPq PVE 314523/2014-6), and SCENIC - ‘Scaling the effects of niche and interaction dynamics on the ecological and evolutionary outcomes of coexistence’ (PID2019-106840GB-C21, funded by AEI/FEDER, UE).

(Rscript.R): R-script for estimating the effects of boat noise on fish movement from the detection pattern provided by a fixed array of acoustic receivers (input.RData): Example of input data for the Rscript.R (AllData): Folder containing all data (receiver detections by individual) used in our work, The datasets are suplementary materials for the article "A State-Space model to derive motorboat noise effects on fish movement from acoustic tracking data". Motorboat noise is recognized as a major source of marine pollution, however little is known about its ecological consequences on coastal systems. We developed a State Space Model (SSM) that incorporates an explicit dependency on motorboat noise to derive its effects on the movement of resident fish that transition between two behavioural states (swimming vs. hidden). To explore the performance of our model, we carried out an experiment where free-living Serranus scriba were tracked with acoustic tags, while motorboat noise was simultaneously recorded. We fitted the generated tracking and noise data into our SSM and explored if the noise generated by motorboats passing at close range affected the movement pattern and the probability of transition between the two states using a Bayesian approach. Our results suggest high among individual variability in movement pattern and transition between states, as well as in fish response to the presence of passing motorboats. These findings suggest that the effects of motorboat noise on fish movement are complex and require the precise monitoring of large numbers of individuals. Our SSM provides a methodology to address such complexity and can be used for future investigations to study the effects of noise pollution on marine fish., Marie S.
