Do adult trees increase conspecific juvenile resilience to recurrent droughts? Implications for forest regeneration
(Ecosphere, 2018) Andivia Muñoz, Enrique; Madrigal González, Jaime; Villar Salvador, Pedro; Zavala, Miguel A.
Recruitment is a bottleneck for forest regeneration especially in semi-arid Mediterranean environments. Ensuring natural forest regeneration is vital for preserving ecosystem function under climate warming and increased frequency and intensity of extreme droughts. Interspecific positive interactions are of paramount importance in these ecosystems. The net outcome of conspecific plant interactions in semi-arid forests, however, has been less explored, particularly the range of environmental conditions for which juveniles benefit from nursing effects. We evaluated the direction and magnitude of intraspecific relationships between adults and juveniles of Pinus pinaster in a dry continental Mediterranean forest in the Iberian Peninsula. We measured the longitudinal shoot elongation of the last 15 yr and foliar functional traits in pine saplings growing under the canopy of adult pines and in open habitats. We examined the growth response to precipitation and the resilience and resistance of growth to two extreme drought events in 2005 and 2012. Our results show likely facilitation of saplings by adult conspecifics. Nursed saplings had a greater size relative to age, longer needles, and faster shoot elongation than saplings in open habitats. In addition, saplings under the canopy were more resistant and resilient to the first severe drought event. However, saplings grown in open habitats were more resilient to the second drought event, which might suggest a shift in the net balance of conspecific interactions with increased drought frequency and with tree ontogeny. These results have a direct application for the adaptation and restoration of semi-arid forest ecosystems under climate change. Currently, adults are used as nurse plants to enhance survival and growth of juveniles. However, this positive effect on sapling performance might shift to negative under scenarios of increasing frequency and intensity of drought events.
La narrativa del artivismo como tendencia en la publicidad. Campaña: “In Spain we call it Igualdad”
(VISUAL REVIEW. International Visual Culture Review / Revista Internacional de Cultura Visual, 2022) Sánchez Serrano, Diana; Ortega Fernández, Eglée Andreina; Toledano Cuervas-Mons, Fernando
La democratización de las comunicaciones a través de los medios sociales ha potenciado un cambio en el perfil del consumidor. Se percibe que la sociedad muestra una conciencia más abierta, centrada en la sostenibilidad, el cuidado del ambiente y la inclusión social. El artivismo, entendido como un fenómeno que saca el arte de los museos y galerías para darle una función social, podría ser una oportunidad para un cambio de modelo donde las emociones que despierta el arte y el activismo se unan para lograr una narrativa con un mayor efecto en la audiencia a quien busca llegar la publicidad.
