dc.description.abstract | Knowledge on the spatial ecology of invasive predators positively contributes to optimizing their management, especially when involving cryptic and secretive species, such as snakes. However, this information is lacking for most invasive snakes, particularly on islands, where they are known to cause severe ecological and socio-economic impacts. This research is focused on assessing the spatial ecology of the California kingsnake (Lampropeltis californiae) on Gran Canaria to strengthen management actions. We monitored 15 radio-tagged individuals once per day on 9–11 days per month from July 2020 to June 2021 to calculate the species' home range and describe annual activity patterns in the invaded range. To account for the species' diel activity during the emergence period, we additionally monitored snakes from January to May 2021 during three consecutive days per month in four different time intervals each day. We detected movement (consecutive detections at least 6 m apart) in 31.68% of the 1146 detections during the whole monitoring period. Movements most frequently detected were shorter than 100 m (82.24%), and among them the range 0–20 m was the most recurrent (27.03%). The mean distance of movement was 62.57 ± 62.62 m in 1–2 days. Average home range was 4.27 ± 5.35 ha—calculated with the Autocorrelated Kernel Density Estimator (AKDE) at 95%—and did not significantly vary with SVL nor sex. We detected an extremely low value of motion variance (0.76 ± 2.62 σ2m) compared to other studies, with a general inactivity period from November to February, January being the less active month of the year. Diel activity was higher during central and evening hours than during early morning and night. Our results should be useful to improve control programs for this invasive snake (e.g., trap placement and visual survey guidance) on Gran Canaria. Our research highlights the importance of gathering spatial information on invasive snakes to enhance control actions, which can contribute to the management of secretive invasive snakes worldwide. | es_ES |
dc.description.sponsorship | We received inestimable support from M. Á. Cabrera (Canary Islands Government), R. Gallo, J. Saavedra, J. Sánchez (GESPLAN S.A), M. Amador and F. Navas (Cabildo de Gran Canaria). Special thanks to A. Melián, who performed surgical procedures and post-surgery care. Our thanks for antennas and receptors on loan from the Department of Zoology (University of La Laguna), Cabildo de Gran Canaria and Asociación de Amigos de las Pardelas. Benjamin M. Marshall, Christen Fleming, J.M. Pérez-García and E. Arrondo provided us with key help and suggestions for ADKE estimates. Guido Vaughan edited English in the final version. Funding was received by the BBVA Foundation (2018 call “Ayudas a Equipos de Investigación Científica en Ecología y Biología de la Conservación”) and the Canary Islands Government (LAMPROIMPACT agreement). JCP was beneficiary of a PhD contract from the Agencia Canaria de la Investigación, Innovación y Sociedad de la Información and the European Social Fund (ESF) (Operational Programme of the Canary Islands 2014–2020—Priority Axis 3: Priority Theme 74, 85 %). MLD was financed by the Cabildo de Tenerife under the TF INNOVA Program 2016-2021 (with funds from MEDI & FDCAN). | es_ES |
