Physiological Stress Mediates the Honesty of Social Signals
Background Extravagant ornaments used as social signals evolved to advertise their bearers' quality. The Immunocompetence Handicap Hypothesis proposes that testosterone-dependent ornaments reliablyExpand

Prevalence and intensity of blood and intestinal parasites in a field population of a Mediterranean lizard, Lacerta lepida
We describe the blood and intestinal parasites in the Ocellated lizard, Lacerta lepida, examining the factors that determine the prevalence and intensity of infection of haemogregarines, and theExpand

Kestrel-Prey Dynamic in a Mediterranean Region: The Effect of Generalist Predation and Climatic Factors
Background Most hypotheses on population limitation of small mammals and their predators come from studies carried out in northern latitudes, mainly in boreal ecosystems. In such regions, manyExpand

A negative association between bromadiolone exposure and nestling body condition in common kestrels: management implications for vole outbreaks.
BACKGROUND Vole outbreaks have been extensively described, along with their impacts on humans, particularly in agricultural areas. The use of rodenticides is a common legal practice to minimise cropExpand

The ornament–condition relationship varies with parasite abundance at population level in a female bird
Environmental heterogeneity is expected to create variation in the ornament–condition relationship. This topic has been studied in males with less attention being given to females. Here, we exploreExpand

Investigating the loss of recruitment potential in red grouse (Lagopus lagopus scoticus): the relative importance of hen mortality, food supply, tick infestation and louping-ill
Ticks and their pathogens cause significant disease and economic loss in many animal populations. Despite this, experiments that test the impact of ticks and tick-borne diseases on wild animalExpand

Evolvability meets biogeography: evolutionary potential decreases at high and low environmental favourability
Understanding and forecasting the effects of environmental change on wild populations requires knowledge on a critical question: do populations have the ability to evolve in response to that change?Expand

Fear in grasslands: the effect of Eurasian kestrels on skylark abundances
Predation has received considerable theoretical and empirical support in population regulation. The effect of predators, however, could be achieved in direct (killing) or indirect effects (such asExpand
