Data from: Facilitation and biodiversity jointly drive mutualistic networks

Gianalberto Losapio, Elizabeth Norton Hasday, Xavier Espadaler, Christoph Germann, Francisco Javier Ortiz-Sánchez, Adrian Pont, Daniele Sommaggio & Christian Schöb
1. Facilitation by nurse plants increases understorey diversity and supports ecological communities. In turn, biodiversity shapes ecological networks and enhances ecosystem functioning. However, whether and how facilitation and increased biodiversity jointly influence community structure and ecosystem functioning remains unclear. 2. We performed a field experiment disentangling the relative contribution of nurse plants and increasing understorey plant diversity in driving pollination interactions. Both the presence of nurse shrubs as well as increased understorey plant diversity increased...

Data from: A new multistage dynamic model for biological control exemplified by the host–parasitoid system Spodoptera exigua–Chelonus oculator

József Garay, Zoltán Sebestyén, Zoltán Varga, Manuel Gámez, Alejandro Torres, José E. Belda & Tomás Cabello
Over the last few decades, important advances have been made in our understanding of host-parasitoid relations and their applications to biological pest control. Not only has the number of agent species increased, but new manipulation techniques for natural enemies have also been empirically introduced, particularly in greenhouse crops. This makes biocontrol more complex, requiring a new mathematical modelling approach appropriate for the optimization of the release of agents. We developed a temperature- and stage-dependent dynamic...

Rare and widespread: Integrating Bayesian MCMC approaches, Sanger sequencing and Hyb-Seq phylogenomics to reconstruct the origin of the enigmatic Rand Flora genus Camptoloma

Victoria Culshaw, Tamera Villaverde, Mario Mairal, Sanna Olsson & Isabel Sanmartín
Premise Genera that are widespread but have a geographically discontinuous distribution and are represented by few species are intriguing. Did they achieve their disjunct distribution recently, or is it ancient in origin? Why are they species-poor? The Rand Flora is a continental-scale floristic pattern in which closely related species appear co-distributed in isolated regions over the edges of Africa and nearby archipelagos. Genus Camptoloma (Scrophulariaceae) is the most notable example, comprising three species isolated from...

Climate-induced plasticity in leaf traits of riparian plants

Juan Rubio-Rios, Javier Pérez, Maria Jacoba Salinas, Encarnación Fenoy, Luz Boyero & José Casas
Aim: Leaf inputs from riparian vegetation and its decomposition play a key role in energy and nutrients transfer in many stream ecosystems. Instream leaf-litter decomposition is mainly driven by leaf traits. Therefore, understanding and predicting leaf traits variation with current environmental changes and its putative effects on stream food webs is a critical challenge. Most studies have focused on the assumed higher interspecific leaf traits variability, with little research addressing an intraspecific perspective. Location: Andalusia,...

Ecogeographical patterns in owl plumage colouration: climate and vegetation cover predict global colour variation

Arianna Passarotto, Arianna Passarotto, Emilio Rodríguez-Caballero, Ángel Cruz-Miralles & Jesús M. Avilés
Aim: Ecogeographical rules link animal colours, especially those produced by melanin pigments, with variation in environmental conditions over wide geographical scales. In particular, Gloger’s rule, coined in two versions for endothermic animals, suggests that tegument darkness would increase at high temperature, as well as in highly humid environments. On the other hand, the thermal melanism hypothesis, predicts that darker colourations should be more frequent in colder areas given their thermoregulation benefits. Location: Global Time period:...
