Data from: Unexpected consequences of a drier world: evidence that delay in late summer rains biases the population sex ratio of an insectRaul Bonal, Marisa Hernández, Josep Maria Espelta, Alberto Muñoz & José M. Aparicio
The complexity of animal life histories makes it difficult to predict the consequences of climate change on their populations. In this paper, we show, for the first time, that longer summer drought episodes, such as those predicted for the dry Mediterranean region under climate change, may bias insect population sex ratio. Many Mediterranean organisms, like the weevil Curculio elephas, become active again after summer drought. This insect depends on late summer rainfall to soften the...
Data from: A longitudinal study of age-related changes in Haemoproteus infection in a passerine birdAlfonso Marzal, Javier Balbontín, Maribel Reviriego, Luz García-Longoria, Carmen Relinque, Ignacio G Hermosell, Sergio Magallanes, Cosme López-Calderón, Florentino De Lope & Anders Pape Moller
Blood parasites such as malaria and related haemosporidians commonly infect vertebrate species including birds. Understanding age-specific patterns of parasite infections is crucial for quantifying the fitness consequences of parasitism for hosts and for understanding parasite transmission dynamics. We analyzed longitudinal and cross-sectional infection data in house martins Delichon urbica, a migratory bird suffering from intense haemosporidian infection. We separated within- from among-individual effects of age on prevalence. Our results showed that the probability of blood...
Data from: The role of fecundity and sexual selection in the evolution of size and sexual size dimorphism in New World and Old World voles (Rodentia: Arvicolinae)Vicente García-Navas, Timothée Bonnet, Raúl Bonal & Erik Postma
Evolutionary ecologists dating back to Darwin (1871) have sought to understand why males are larger than females in some species, and why females are the larger sex in others. Although the former is widespread in mammals, rodents and other small mammals usually exhibit low levels of sexual size dimorphism (SSD). Here, we investigate patterns of sexual dimorphism in 34 vole species belonging to the subfamily Arvicolinae in a phylogenetic comparative framework. We address the potential...
Data from: The interplay among acorn abundance and rodent behavior drives the spatial pattern of seedling recruitment in mature Mediterranean oak forestsPau Sunyer, Ester Boixadera, Alberto Muñoz, Raúl Bonal & Josep Maria Espelta
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. We designed a field study to assess the interplay between environment (vegetation structure, seed abundance, rodent abundance) and behavior (seed dispersal and predation by rodents, and rooting by wild boars), and their contribution to the spatial patterns of seedling recruitment in a Mediterranean...
To evaluate progress on political biodiversity objectives, biodiversity monitoring provides information on whether intended results are being achieved. Despite scientific proof that monitoring and evaluation increase the (cost) efficiency of policy measures, cost estimates for monitoring schemes are seldom available, hampering their inclusion in policy programme budgets. Empirical data collected from 12 case studies across Europe were used in a power analysis to estimate the number of farms that would need to be sampled per...
Data from: When Siberia came to the Netherlands: the response of continental black-tailed godwits to a rare spring weather eventNathan R. Senner, Mo A. Verhoeven, José M. Abad-Gómez, Jorge S. Gutiérrez, Jos C. E. W. Hooijmeijer, Rosemarie Kentie, José A. Masero, T. Lee Tibbitts & Theunis Piersma
1. Extreme weather events have the potential to alter both short- and long-term population dynamics as well as community- and ecosystem-level function. Such events are rare and stochastic, making it difficult to fully document how organisms respond to them and predict the repercussions of similar events in the future. 2. To improve our understanding of the mechanisms by which short-term events can incur long-term consequences, we documented the behavioural responses and fitness consequences for a...
