Introduction
I am mainly interested in the ecology and evolution of wild rodent populations, and in BIOLOGY in general. We study the ecology and public health impacts of colonizing populations of common voles in agricultural landscapes of NW Spain. We have recently demonstrated empirically the role of wild rodents as amplification and spillover agents of tularemia, and that fluctuations in the abundance of wild mammals play a key role in the epidemiology and risk of this zoonotic disease across Europe.

Common voles (Microtus arvalis) are widespread in the European agricultural landscape from central Spain to central Russia. During population outbreaks, significant damage to a variety of crops is caused and the risk of pathogen transmission from voles to people increases. In 2019, increasing or unusually high common vole densities have been report...
Article
Small mustelids such as weasels are highly specialized predators of small rodents. Their diminutive size allows hunting for prey underground, but also means that they are bite-sized predators, preyed upon by other larger predators. Habitat use by weasels is therefore expected to depend not only on prey abundance, but also on predation risk. We repo...
Article
Weasels are bite-sized predators highly specialized on small rodents and hypothesized to cause the population cycles of these prey in northern Europe. We studied the numerical response of the common weasel (Mustela nivalis) to fluctuating abundances of common voles (Microtus arvalis) in southern Europe. We show that both predator and prey exhibited...

We detected Francisella tularensis and Bartonella spp. in fleas parasitizing common voles (Microtus arvalis) northwestern Spain; mean prevalences were 6.1% and 51%, respectively. Contrasted vector–host associations in the prevalence of these bacteria suggest that fleas have distinct roles in the transmission cycles of each pathogen in nature.
Article
Diseases and host dynamics are linked, but their associations may vary in strength, be time lagged, and depend on environmental influences. Where a vector is involved in disease transmission, its dynamics are an additional influence, and we often lack a general understanding on how diseases, hosts and vectors interact. We report on the occurrence o...

Common voles are a main European facultative, fossorial, farmland rodent pest that can greatly reduce crop yields during population outbreaks. Crop protection against common voles is a complex task that requires the consideration of a set of preventive and control measures within an integrated pest management strategy. A possible option could be to...

Spatial capture-recapture modelling (SCR) is a powerful analytical tool to estimate density and derive information on space use and behaviour of elusive animals. Yet, SCR has been seldom applied to the study of ecologically keystone small mammals. Here we highlight its potential and requirements with a case study on common voles (Microtus arvalis)....

Bai et al. (2018) determined that China's increasing milk demand is expected to raise global greenhouse gas (GHG) emissions by 35%, expand dairy land by 32% and lift nitrogen pollution by 48%. Producing the additional milk in China adds to the environmental cost of animal feed transfers (from 1 to 6.2 Tg of alfalfa), while importing the extra milk...

By experimentally adding or removing parasites, it has been shown that macro-parasites may regulate populations of their hosts. At an individual level, ecto-parasites can affect body condition, growth, life span, energy expenditure, litter size, foraging, and juvenile survival of hosts, which could translate into effects on host population abundanc...

Tularemia in humans in northwestern Spain is associated with increases in vole populations. Prevalence of infection with Francisella tularensis in common voles increased to 33% during a vole population fluctuation. This finding confirms that voles are spillover agents for zoonotic outbreaks. Ecologic interactions associated with tularemia preventio...

Small rodents are common inhabitants of farmlands where they play key ecosystem roles but can also be major pests when overabundant, causing crop damages and significant economic losses. Agricultural landscapes are characterised by high fragmentation with remnant semi-natural habitats being typically restricted to narrow field margins. These linear...

In many European regions, most microtine rodents exhibit multi-annual fluctuations in abundance and can cause significant crop damage and economical losses when they are overabundant during population outbreaks. In addition, they can be reservoirs of multiple pathogens responsible of serious zoonotic diseases to humans and livestock. Therefore, und...

Reproduction is the most fundamental mechanism for maintaining life over time. In Rodents reproduction rates are typically high, although temporal changes in the reproductive output of individuals are an important component of population change. In populations that periodically experience strong fluctuations in abundance, reproductive strategies an...

Understanding the ecological factors that determine the population growth rate of rodent populations is fundamental in order to study population dynamics, and to predict and better manage population outbreaks. This is particularly important for species that spill over diseases or cause significant crop damages when overabundant, like common voles i...
Article
During last decades, large tularemia outbreaks in humans have coincided in time and space with population outbreaks of common voles in North-western Spain, leading us to hypothesize that this rodent species acts as a key spillover agent of Francisella tularensis in the region. Here, we evaluate for the first time a potential link between irruptive...

Investment in sperm numbers is a key predictor of success in sperm competition and there is usually a positive relationship between sperm competition level and male reproductive effort on ejaculates, which is often measured using relative testes size (RTS). Demographic processes can drasti- cally alter levels of sperm competition and we should expe...

Sperm viability, acrosome integrity, motility, and swimming velocity are determinants of male fertility and exhibit an extreme degree of variation among closely related species. Many of these sperm parameters are associated with sperm ATP content, which has led to predictions of tradeoffs between ATP content and sperm motility and velocity. Selecti...

The common vole, considered a rodent pest when overabundant in agricultural areas, was traditionally absent from the agricultural plains of Castilla-y-León, NW Spain. However, it rapidly invaded ca. 50.000 km2 of agricultural land, where regular outbreaks have caused crop damages and conflict with farmers. To better understand the factors that trig...

The intensification of agricultural landscapes is usually associated with increases in field size and reduction of natural and semi-natural habitats, particularly field margins and fallows. These habitats are crucial for small mammals, as permanent, less altered habitats, or as corridors for dispersion. In this study, we assessed seasonal abundance...

Common voles (Microtus arvalis) can be abundant in agricultural landscapes of Europe and their numbers can strongly fluctuate through time, which confers them a key ecological role for the structure and dynamics of local communities. Also, they are often declared and controlled as agricultural pests as can cause significant socio-economical and hea...

Sexual selection may promote divergence between populations. Sperm competition, one form of post-copulatory sexual selection, is known to favour changes in ejaculate quality and sperm swimming speed, which improve ejaculate competitiveness. We thus tested the prediction that natural populations from species with high levels of sperm competition sho...

Sperm competition favors increases in relative testes mass and production efficiency, and changes in sperm phenotype that result in faster swimming speeds. However, little is known about its effects on traits that contribute to determine the quality of a whole ejaculate (i.e., proportion of motile, viable, morphologically normal and acrosome intact...

Many studies show that prey should not flee immediately from approaching predators, but should adjust their fleeing distance to minimize flight costs. We explored a new scenario where an ambush predator appears close to a relatively cryptic prey, that the predator has not yet detected. Then, instead of approaching further, the predator stops and st...

When confronted with a predator, prey are often in close proximity to conspecifics. This situation has generated several hypotheses regarding antipredator strategies adopted by individuals within groups of gregarious species, such as the "risk dilution," "early detection," or "collective detection" effects. However, whether short-term temporary agg...
