The effects of local climate on the correlation between weather and seed production differ in two species with contrasting masting habit / Bogdziewicz, Michał (Department of Systematic Zoology, Faculty of Biology, Adam Mickiewicz University) ; Szymkowiak, Jakub (Population Ecology Lab, Faculty of Biology, Adam Mickiewicz University) ; Fernández Martínez, Marcos (Centre of Excellence PLECO (Plant and Ecosystems), Department of Biology, University of Antwerp) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals)
Many plant species present inter-annual cycles of seed production (mast seeding), with synchronized high seed production across populations in some years. Weather is believed to be centrally involved in triggering masting. [...]

166 p, 9.8 MB The role of landscape and species attributes in insect community assembly, population genetics and plant-insect interactions in expanding Quercus ilex forests / Ruiz Carbayo, Helena, autor. ; Pino i Vilalta, Joan, supervisor acadèmic. ; Espelta Morral, Josep Maria, supervisor acadèmic. ; Bonal Andrés, Raúl, supervisor acadèmic. ; Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia. ; Centre de Recerca Ecològica i Aplicacions Forestals.
Los mecanismos responsables de la colonización y coexistencia de las especies en los hábitats, es uno de los mayores rompecabezas en ecología de comunidades. Varias teorías, entre ellas la teoría de nicho, neutral y de coexistencia, han intentado explicar la biodiversidad observada en los ecosistemas naturales como el resultado de procesos determinísticos, neutrales o una combinación de ambos, respectivamente. [...]
The mechanisms driving species colonization and coexistence in habitats, is one of the main puzzles in community ecology. Several theories, including niche, neutral and coexistence theories, have tried to explain the biodiversity observed in natural ecosystems as the result of deterministic, neutral, or a combination of both processes, respectively.

13 p, 1.2 MB Role of seed size, phenology, oogenesis and host distribution in the specificity and genetic structure of seed weevils (Curculio spp.) in mixed forests / Arias-LeClaire, Harold (Centre de Recerca Ecològica i Aplicacions Forestals) ; Bonal, Raúl (Universidad de Extremadura. Grupo de Investigación Forestal) ; García López, Daniel (Universitat Autònoma de Barcelona. Departament de Biologia Animal, Biologia Vegetal i d'Ecologia) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals)
Synchrony between seed growth and oogenesis is suggested to largely shape trophic breadth of seed‐feeding insects and ultimately to contribute to their co‐existence by means of resource partitioning or in the time when infestation occurs. [...]

7 p, 1.6 MB Plantes anyívoles : entre l’abstinència i la disbauxa reproductiva / Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals) ; Fernández Martínez, Marcos (Centre de Recerca Ecològica i Aplicacions Forestals) ; Bogdziewicz, Michał (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals)
La majoria de plantes perennes produeixen llavors cada any, però n’hi ha algunes que mostren un comportament reproductiu estrany: les seves poblacions produeixen extraordinàries collites de manera erràtica i sincrònica, però passen alguns anys pràcticament sense reproduir-se. [...]
Summary: Masting plants: Why combine abstinence and lust in reproduction? – Most perennial plants produce seeds every year, but some species show a bizarre reproductive behaviour: they produce bumper crops randomly and synchronously in some years, while in other years they produce virtually no seeds.

24 p, 1.4 MB The Moran effect and environmental vetoes : phenological synchrony and drought drive seed production in a Mediterranean oak / Bogdziewicz, Michał (Centre de Recerca Ecològica i Aplicacions Forestals) ; Fernández Martínez, Marcos (Centre de Recerca Ecològica i Aplicacions Forestals) ; Bonal, Raúl (Instituto de Investigación de la Dehesa) ; Belmonte, Jordina (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals)
Masting is the highly variable production of synchronized seed crops, and is a common reproductive strategy in plants. Weather has long been recognized as centrally involved in driving seed production in masting plants. [...]

8 p, 1.3 MB Nature beyond linearity : meteorological variability and Jensen’s inequality can explain mast seeding behaviour / Fernández Martínez, Marcos (Centre de Recerca Ecològica i Aplicacions Forestals) ; Bogdziewicz, Michał (Centre de Recerca Ecològica i Aplicacions Forestals) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals)
Mast seeding, the extremely variable and synchronized production of fruits, is a common reproductive behavior in plants. Weather is centrally involved in driving masting. Yet, it is often claimed that it cannot be the sole proximate cause of masting because weather is less variable than fruit production and because the shape of their distributions differ. [...]

13 p, 582.3 KB Beyond predator satiation : masting but also the effects of rainfall stochasticity on weevils drive acorn predation / Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals) ; Arias-LeClaire, Harold (Centre de Recerca Ecològica i Aplicacions Forestals) ; Fernández Martínez, Marcos (Centre de Recerca Ecològica i Aplicacions Forestals) ; Doblas Miranda, Enrique (Centre de Recerca Ecològica i Aplicacions Forestals) ; Muñoz, Alberto (Universidad Complutense de Madrid. Departamento de Didactica de las Ciencias Experimentales) ; Bonal, Raúl (Instituto de Investigación de la Dehesa)
Escaping seed predation is a classic “economy of scale” hypotheses (predator satiation hypothesis, Psh) to explain the selection for the synchronous production of massive and nil seed crops (masting) in plants. [...]

10 p, 459.5 KB Trade-offs between vegetative growth and acorn production in Quercus lobata during a mast year : the relevance of crop size and hierarchical level within the canopy / Sanchez-Humanes, Belén (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sork, Victoria L. (University of California. Department of Ecology and Evolutionary Biology) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals)
The concept of trade-offs between reproduction and other fitness traits is a fundamental principle of life history theory. For many plant species, the cost of sexual reproduction affects vegetative growth in years of high seed production through the allocation of resources to reproduction at different hierarchical levels of canopy organization.

13 p, 348.8 KB The interplay among acorn abundance and rodent behavior drives the spatial pattern of seedling recruitment in mature Mediterranean oak forests / Sunyer, Pau (Centre de Recerca Ecològica i Aplicacions Forestals) ; Boixadera, Ester (Universitat Autònoma de Barcelona. Servei d’Estadística Aplicada) ; Muñoz Muñoz, Alberto (Centre de Recerca Ecològica i Aplicacions Forestals) ; Bonal, Raúl (Centre de Recerca Ecològica i Aplicacions Forestals) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals)
The patterns of seedling recruitment in animal-dispersed plants result from the interactions among environmental and behavioral variables. However, we know little on the contribution and combined effect of both kinds of variables. [...]

41 p, 1.2 MB Tropical insect diversity : evidence of greater host specialization in seed-feeding weevils / Peguero Gutiérrez, Guillermo (Centre de Recerca Ecològica i Aplicacions Forestals) ; Bonal, Raúl (Instituto de Investigación de la Dehesa) ; Sol, Daniel (Centre de Recerca Ecològica i Aplicacions Forestals) ; Muñoz Muñoz, Alberto (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sork, Victoria L. (University of California. Department of Ecology and Evolutionary Biology) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals)
Host specialization has long been hypothesized to explain the extraordinary diversity of phytophagous insects in the tropics. However, addressing this hypothesis has proved challenging because of the risk of over-looking rare interactions, and hence biasing specialization estimations, and the difficulties to separate the diversity component attributable to insect specialization from that related to host diversity. [...]
