Allee effects in an invasive social wasp: an experimental study in colonies of Vespula germanica
(Springer Nature, 2023-09)Allee effects rely on the existence of mutually beneficial intraspecific interactions that increase individual fitness and per capita growth rate, as the number of individuals in a population or group increases. When the ... -
Avispas sociales invasoras en la Patagonia Argentina
(Universidad Nacional del Comahue, 2018-02)Las invasiones biológicas son uno de los problemas ambientales más serios de la actualidad. Sólo una fracción pequeña de las especies que arriban a nuevos sitios logra establecerse exitosamente provocando impactos ... -
Dinámica de la dispersión y actividad de la avispa exótica Vespula germanica F. (Hymenoptera: Vespidae) en Argentina
(Centro Regional Universitario Bariloche, Universidad Nacional del Comahue, 2013)Las invasiones biológicas son un tema central de la ecología. Por un lado, la introducción de especies exóticas brinda un excelente escenario para estudiar procesos demográficos y las interacciones sobre la estructura de ... -
