- PublicationEcología del gato montés ("Felis silvestris") y su relación con el conejo de monte ("Oryctolagus cuniculus")(Universidad Complutense de Madrid, Servicio de Publicaciones, 2009-04-23) Lozano Mendoza, Jorge; Virgós Cantalapiedra, EmilioSe ha estudiado la ecología del gato montés y su relación particular con el conejo de monte tanto en preferencias de hábitat, dieta, relaciones con ungulados y tendencias de población. El gato montés fue más abundante a escala de paisaje en los mosaicos formados por matorral y pastizal, siendo el matorral además la variable de hábitat más claramente asociada con la especie en todas las escalas espaciales. Por tanto, se identifica al matorral como un elemento estructural del medio clave para la especie. La abundancia de gato montés se asocia positivamente con la abundancia de conejo. La presencia de conejo desplaza a los roedores en la dieta del gato montés, tanto a escala regional como a escala biogeográfica, aunque en ausencia de conejo los roedores dominan la dieta. Por tanto, el gato montés se comporta como un especialista trófico facultativo, con preferencia del conejo sobre los roedores. La diversidad trófica del gato montés, a escala biogeográfica, es mayor en las áreas de la Región Mediterránea por la inclusión de presas alternativas como conejo e invertebrados. El gato montés fue menos abundante en zonas con una elevada carga de ungulados (ciervo y jabalí), donde también existió una menor presencia y abundancia de conejo, por lo que una excesiva densidad de ungulados se postula como una amenaza añadida para la especie, debido probablemente a la disminución de recursos tróficos que los ungulados causan por su actividad. La población de gato montés ha permanecido estable a escala regional en el área estudiada (Madrid y norte de Toledo) aproximadamente durante la última década. Las variaciones locales de población del gato montés registradas no tuvieron relación ni con las características de hábitat ni con la dinámica poblacional del conejo.
- PublicationUsually hated, sometimes loved: A review of wild ungulates' contributions to people(Elsevier, 2021-08-14) Pascual-Rico, Roberto; Morales-Reyes, Zebensui; Aguilera-Alcalá, Natividad; Olszańska, Agnieszka; Sebastián-González, Esther; Naidoo, Robin; Moleón, Marcos; Lozano Mendoza, Jorge; Botella, Francisco; Wehrden, Henrik von; Martín-López, Berta; Sánchez-Zapata, José A.Nature's contributions to people (NCP) may be both beneficial and detrimental to humans' quality of life. Since our origins, humans have been closely related to wild ungulates, which have traditionally played an outstanding role as a source of food or raw materials. Currently, wild ungulates are declining in some regions, but recovering in others throughout passive rewilding processes. This is reshaping human-ungulate interactions. Thus, adequately understanding the benefits and detriments associated with wild ungulate populations is necessary to promote humanungulate co-existence. Here, we reviewed 575 articles (2000-2019) on human-wild ungulate interactions to identify key knowledge gaps on NCP associated with wild ungulates. Wild ungulate research was mainly distributed into seven research clusters focussing on: (1) silvicultural damage in Eurasia; (2) herbivory and natural vegetation; (3) conflicts in urban areas of North America; (4) agricultural damage in Mediterranean agro-ecosystems; (5) social research in Africa and Asia; (6) agricultural damage in North America; (7) research in natural American Northwest areas. Research mostly focused on detrimental NCP. However, the number of publications mentioning beneficial contributions increased after the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services conceptual framework was implemented. Human-ungulate interactions' research was biased towards the Global North and Cervidae, Suidae and Bovidae families. Regarding detrimental NCP, most publications referred to production damage (e.g. crops), followed by biodiversity damage, and material damage (e.g. traffic collisions). Regarding beneficial NCP, publications mainly highlighted non-material contributions (e.g. recreational hunting), followed by material NCP and regulating contributions (e.g. habitat creation). The main actions taken to manage wild ungulate populations were lethal control and using deterrents and barriers (e.g. fencing), which effectiveness was rarely assessed. Increasing research and awareness about beneficial NCP and effective management tools may help to improve the conservation of wild ungulates and the ecosystems they inhabit to facilitate people-ungulate co-existence in the Anthropocene.
- PublicationThe competitor release effect applied to carnivore species: how red foxes can increase in numbers when persecuted(Museo de Ciencias Naturales de Barcelona, 2013) Lozano Mendoza, Jorge; Casanovas, Jorge G.; Virgós, Emilio; Zorrilla Barroso, José ManuelThe competitor release effect applied to carnivore species: how red foxes can increase in numbers when persecuted.— The objective of our study was to numerically simulate the population dynamics of a hypothetical community of three species of small to medium–sized carnivores subjected to non–selective control within the context of the competitor release effect (CRE). We applied the CRE to three carnivore species, linking interspecific competition with predator control efforts. We predicted the population response of European badger, the red fox and the pine marten to this wildlife management tool by means of numerical simulations. The theoretical responses differed depending on the intrinsic rate of growth (r), although modulated by the competition coefficients. The red fox, showing the highest r value, can increase its populations despite predator control efforts if control intensity is moderate. Populations of the other two species, however, decreased with control efforts, even reaching extinction. Three additional theoretical predictions were obtained. The conclusions from the simulations were: 1) predator control can play a role in altering the carnivore communities; 2) red fox numbers can increase due to control; and 3) predator control programs should evaluate the potential of unintended effects on ecosystems.
- PublicationHuman-carnivore relations: conflicts, tolerance and coexistence in the American West(IOP Publishing, 2019-12-06) Expósito-Grandados, Mónica; Castro, Antonio J.; Lozano Mendoza, Jorge; Aznar-Sanchez, José A.; Carter, Neil H.; Requena-Mullor, Juan M.; Malo, Aurelio F.; Olszańska, Agnieszka; Morales Reyes, Zebensui; Moleón, Marcos; Sánchez-Zapata, José A.; Cortés-Avizanda, Ainara; Fischer, Joern; Martín López, BertaCarnivore and humans live in proximity due to carnivore recovery efforts and ongoing human encroachment into carnivore habitats globally. The American West is a region that uniquely exemplifies these human-carnivore dynamics, however, it is unclear how the research community here integrates social and ecological factors to examine human-carnivore relations. Therefore, strategies promoting human-carnivore coexistence are urgently needed. We conducted a systematic review on human-carnivore relations in the American West covering studies between 2000 and 2018. We first characterized human-carnivore relations across states of the American West. Second, we analyzed similarities and dissimilarities across states in terms of coexistence, tolerance, number of ecosystem services and conflicts mentioned in literature. Third, we used Bayesian modeling to quantify the effect of social and ecological factors influencing the scientific interest on coexistence, tolerance, ecosystem services and conflicts. Results revealed some underlying biases in humancarnivore relations research. Colorado and Montana were the states where the highest proportion of studies were conducted with bears and wolves the most studied species. Non-lethal management was the most common strategy to mitigate conflicts. Overall, conflicts with carnivores were much more frequently mentioned than benefits. We found similarities among Arizona, California, Utah, and New Mexico according to how coexistence, tolerance, services and conflicts are addressed in literature. We identified percentage of federal/private land, carnivore family, social actors, and management actions, as factors explaining how coexistence, tolerance, conflicts and services are addressed in literature. We provide a roadmap to foster tolerance towards carnivores and successful coexistence strategies in the American West based on four main domains, (1)the dual role of carnivores as providers of both beneficial and detrimental contributions to people, (2)social-ecological factors underpinning the provision of beneficial and detrimental contributions, (3)the inclusion of diverse actors, and (4) cross-state collaborative management.
