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...

Community-level reorganizations following migratory pollinator dynamics along a latitudinal gradient

Ainhoa Magrach, Carlos Lara, Márquez-Luna Ubaldo, Sergio Díaz-Infante & Ingrid M. Parker
Predicting how communities re-arrange in response to changes in species composition remains a key challenge in ecology. Migratory species, which enter and leave communities across latitudinal gradients, offer us a unique opportunity to evaluate community and species-level responses to a shift in community composition. We focused on a migratory hummingbird and the communities that host it along a latitudinal and species diversity gradient. Our results show higher niche overlap in more diverse communities, allowing resident...

Data from: Drought legacies are short, prevail in dry conifer forests and depend on growth variability.

Antonio Gazol, J. Julio Camarero, Raúl Sánchez-Salguero, Sergio Vicente-Serrano, Xavier Serra-Maluquer, Emilia Gutiérrez, Martín De Luis, Gabriel Sangüesa-Barreda, Klemen Novak, Vicente Rozas, Pedro A. Tiscar, Juan C. Linares, Edurne Martínez Del Castillo, Montse Ribas, Ignacio García-González, Fernando Silla, Álvaro Camisón, Mar Genova, Jose Miguel Olano, Ana-Maria Hereș, Jorge Curiel-Yuste, Luis A. Longares, Andrea Hevia, Miquel Tomas-Burguera & Juan Galván
The negative impacts of drought on forest growth and productivity last for several years generating legacies, although the factors that determine why such legacies vary across sites and tree species remain unclear. We used an extensive network of tree-ring width (RWI, ring-width index) records of 16 tree species from 567 forests, and high-resolution climate and NDVI datasets across Spain during the common period 1982‒2008 to test the hypothesis that climate conditions and growth features modulate...

Data from: Anthropogenic ecosystem disturbance and the recovery debt

David Moreno Mateos, Edward B. Barbier, Peter C. Jones, Holly P. Jones, James Aronson, Jose A. Lopez-Lopez, Michelle L. McCrackin, Paula Meli, Daniel Montoya & José Rey Benayas
Ecosystem recovery from anthropogenic disturbances, either without human intervention or assisted by ecological restoration, is increasingly occurring worldwide. As ecosystems progress through recovery, it is important to estimate any resulting deficit in biodiversity and functions. Here we use data from 3,035 sampling plots worldwide, to quantify the interim reduction of biodiversity and functions occurring during the recovery process (that is, the ‘recovery debt’). Compared with reference levels, recovering ecosystems run annual deficits of 46–51% for...

Data from: Ecosystem response to interventions: lessons from restored and created wetland ecosystems

David Moreno-Mateos, Paula Meli, María Isabel Vara-Rodriguez & James Aronson
1. Current efforts to restore and create ecosystems require greater understanding of ecosystems’ responses to commonly used physical and biological intervention approaches to overcome ecological and technological limitations. 2. We estimated effect sizes from measurements of biotic assemblage structure and biogeochemical functions at 628 restored and created wetlands globally, in comparison with 499 reference wetlands. We studied the recovery trajectories of wetlands where different restoration or creation approaches were used under different environmental settings. 3....

Data from: Altered leaf litter quality exacerbates the negative impact of climate change on decomposition

Iván Prieto, Maria Almagro, Felipe Bastida & José Ignacio Querejeta
1.Leaf litter decomposition is a key component of global biogeochemical cycles that influences soil carbon storage, nutrient availability and plant productivity. Ongoing climate change will lead to warmer and drier conditions in many dryland regions, potentially affecting litter decomposition and nutrient dynamics. Climate change effects can be direct and/or indirect, e.g. through changes in litter quality, yet their relative importance on litter decomposition remains unclear. 2. We conducted a manipulative study in a semiarid shrubland...

LeWoS: A universal leaf‐wood classification method to facilitate the 3D modelling of large tropical trees using terrestrial LiDAR

Di Wang, Stéphane Momo Takoudjou & Eric Casella
1. Leaf-wood separation in terrestrial LiDAR data is a prerequisite for non-destructively estimating biophysical forest properties such as standing wood volumes and leaf area distributions. Current methods have not been extensively applied and tested on tropical trees. Moreover, their impacts on the accuracy of subsequent wood volume retrieval were rarely explored. 2. We present LeWoS, a new fully automatic tool to automate the separation of leaf and wood components, based only on geometric information at...

Data from: On the links between nature's values and language

Dylan Inglis & Unai Pascual
1. Recent research into the plural values about nature is focusing on relational values as a concept through which to better understand the breadth and importance of situated human-nature relations. However, potential relevance of language as a mediating factor in relational values has not been sufficiently examined. 2. In order to investigate links between language and values, we explore the influence of the ancient non-Indo-European Basque language (‘Euskara’) upon people’s relationships with mountain forests in...

Motivational crowding in PES: experiment results

Bosco Lliso
Nature is perceived and valued in many different ways. Often, the types of values that are the most important to people depend on how they cognitively frame desirable human-nature relations. For instance, the value of nature can be seen through a utilitarian lens, e.g., as providing ecosystem services for humans. Alternatively, it can also be considered valuable for non-instrumental reasons, e.g., for its sacred or spiritual significance. In this paper, we use a framed field...
