A cryptic hybrid zone reveals the genomic basis of flower colour variation in a plant with a large and complex genome

Pascaline Salvado, Anaïs Gibert, Slimane Chaïb, Delphine Raviglione et autres

Flower colour is known to be an automatic magic trait, undergoing divergent selection pressures exerted by distinct pollinators and involved in reproductive isolation. However, variation at this trait may also results from other eco-evolutionary factors whose interpretation requires throughout context-specific analyses. Here, …

La difícil convivencia entre escalada deportiva y plantas raras. El ejemplo de Asplenium seelosii subsp. catalaunicum.

Pere Aymerich

We present a case of rapid decline in a population of Asplenium seelosii subsp. catalaunicum, a threatened endemic fern. This study examines whether the decline of this species in Riugréixer (northern Catalonia) is the result of variations in the practice of climbing. …

Se da a conocer la presencia en los Pirineos de plantas que son asignables a Petrosedum thartii, de acuerdo con los conocimientos actuales sobre el difícil complejo de los Petrosedum de flores amarillas. Petrosedum thartii es una especie que hasta ahora no …

Introduced fish reduce the occurrence of shrews in alpine lakes

Lucia Bello, Pere Aymerich, Teresa Buchaca, Jennifer Caner et autres

Widespread fish introductions into originally fishless mountain lakes have had severe consequences for native biota, including aquatic macroinvertebrates, which provide important food subsidies for terrestrial and semiaquatic insectivores like shrews (Fam. Soricidae). Since both fish and shrews rely on aquatic macroinvertebrates as …

Effect of introduction pathways on the invasion success of non-native plants along environmental gradients

Marc Riera, Joan Pino, Llorenç Sáez, Pere Aymerich et autres

Abstract Our understanding on the role of introduction pathways on plant invasions is incomplete because their interaction with other factors remains poorly studied. We contributed to filling this knowledge gap, by analysing temporal trends in pathway importance, pathway-specific differences in the invaded …
