Data from: The role of nutritional impairment in carbon-water balance of silver fir drought-induced dieback

Ester González De Andrés, Antonio Gazol, José Ignacio Querejeta, José M. Igual, Michele Colangelo, Raúl Sánchez-Salguero, Juan Carlos Linares & J. Julio Camarero
Rear-edge populations at the xeric distribution limit of tree species are particularly vulnerable to forest dieback triggered by drought. This is the case of silver fir (Abies alba) forests located in the southwestern of Europe. While silver fir drought-induced dieback patterns have been previously explored, information on the role played by nutritional impairment is lacking despite its potential interactions with tree carbon-water balances. We performed a comparative analysis of radial growth, intrinsic water-use efficiency (iWUE),...

Unravelling the mystery of red flowers in the Mediterranean Basin: How to be conspicuous in a place dominated by hymenopteran pollinators

Melissa León-Osper & Eduardo Narbona
Red-flowered species have traditionally been related to ornithophily, and the 'bee avoidance' hypothesis, i.e. red flower coloration is a way to reduce visits from hymenopterans, has been proposed to explain this association. In the Mediterranean Basin, ornithophily is almost absent, and hymenopterans are the most common group of pollinators. The fact that hymenopterans are virtually red-blind raises the question of how red-flowered species are pollinated in this region. Are these flowers pollinated by other groups...

Data from: Climate matching and anthropogenic factors contribute to the colonisation and extinction of local populations during avian invasions

Laura Cardador, José L Tella, Julie Louvrier, José D Anadón, Pedro Abellán & Martina Carrete
Concern about the impacts of biological invasions has generated a great deal of interest in understanding factors that determine invasion success. Most of our current knowledge comes from static approaches that use spatial patterns as a proxy of temporal processes. These approaches assume that species are present in areas where environmental conditions are the most favourable. However, this assumption is problematic when applied to dynamic processes such as species expansions when equilibrium has not been...

Fruit-feeding butterfly populations respond to variation in adult food availability: evidence from longitudinal body mass and abundance data

Freerk Molleman, Jorge Granados-Tello, Colin Chapman & Toomas Tammaru
The degree to which variation in adult food availability affects the population dynamics of a species depends on its position on the capital-income breeding continuum. The long-lived butterflies that feed on fruits as adults constitute an example of Lepidoptera with a high degree of income breeding. For three species of fruit-feeding butterflies in Uganda, we assessed the contribution of the income to breeding in the wild, and the consequences of variation in fruit availability for...

Tree growth response to drought partially explains regional-scale growth and mortality patterns in Iberian forests

Antonio Gazol, J. Julio Camarero, Raúl Sánchez-Salguero, Miguel A. Zavala, Xavier Serra-Maluquer, Emilia Gutiérrez, Martín De Luis, Gabriel Sangüesa-Barreda, Klemen Novak, Vicente Rozas, Pedro A. Tíscar, Juan C. Linares, Edurne Martínez Del Castillo, Montse Ribas, Ignacio García-González, Fernando Silla, Álvaro Camison, Mar Génova, José M. Olano, Ana-Maria Hereş, Jorge Curiel Yuste, Luis A. Longares, Andrea Hevia, J. Diego Galván & Paloma Ruiz-Benito
To quantify responses to drought from different data sources we take advantage of an extensive network of cross-dated tree-ring data with increment cores from 16 tree species sampled across the Spanish Iberian Peninsula (hereafter abbreviated as RWI-net), and of the Spanish National Forest Inventory (hereafter abbreviated as NFI) sampling tree and plot level data each km in forested areas. We selected the five most severe droughts that have affected each selected RWI-net population in the...
