Agricultural activities and road construction have been reported as major causes of landscape fragmentation. We have assessed the distribution of warrens of a burrowing mammal, the European rabbit (Oryctolagus cuniculus), in natural vegetation patches within an agricultural mosaic crossed by a highway. The rabbit is considered a key species in Mediterranean ecosystems because of both, its role as a prey, and as an engineering species. We have specifically considered the occurrence and abundance of warrens (a group of entrances < 2 m from each other) as well as their size (number of entrances) and their spatial distribution within natural vegetation patches. Results showed that rabbit occurrence is more likely in natural vegetation patches with steeper slopes, more circular shapes and closer to the highway. In addition, there were more warrens in larger patches and larger warrens were found in larger, steeper, elongated patches. More frequent presence and greater warren abundance found close to the highway may be due to the barrier effect, but attraction due to habitat suitability and protection from predators have also been suggested in the literature. Besides the relevance of the different mechanisms implied, our results suggest that the presence of roads modifies the presence of rabbit warrens across a fragmented agricultural landscape. In this sense, roads could impact rabbit density and, therefore, present relevant implications for the population persistence of this species; also, roads could indirectly affect the distribution and welfare of rabbits' predators.

A method for estimating body mass of European rabbitsOryctolagus cuniculus (Linnaeus, 1758) based on tooth dimensions is proposed. Regression models identified significant relationships between the body mass of 87 rabbits and individual tooth length, breadth, product of tooth length and breadth, and whether or not the individual was infected with myxomatosis. Dimensions of 10 of 14 different teeth explained over 80% of variation in body mass, and those teeth were selected as adequate predictors of rabbit body mass. Models were tested using teeth from 16 additional rabbits of known body mass. Body mass, predicted on the basis of 9 of the 10 selected teeth, was statistically indistinguishable from the observed values for all 16 individuals. When myxomatosis infection status of the rabbit was included in the model, all 10 selected teeth yielded predictions statistically indistinguishable from those observed. Prediction errors can be computed permitting statistical comparison of the average predicted value of body mass from different samples of rabbits. The model is useful in estimating rabbit body masses from teeth recovered from feces of predators and it will facilitate testing of hypotheses on size-selective predation. The method was applied to rabbit teeth found in fecal samples from the Iberian lynxLynx pardinus collected over a one-year period. Lynx preyed preferentially upon younger rabbits during the peak breeding period of this lagomorph.

As European rabbits Oryctolagus cuniculus (Linnaeus, 1758) in SW Spain face high prédation pressure, some antipredator tactics are expected. We examined rabbit group size in relation to the safety of the cover (sparse or dense), and the proximity to shrub cover. Stem density influenced the distance rabbits ventured from shrub; rabbits ventured greater distances when stem density in cover was higher. Rabbit group size was related to the distance to cover; solitary animals remained closer to protective cover, whereas rabbits in groups (> 3 animals) foraged further from cover. These results are consistent with the hypothesis that the formation of rabbit groups is related to defense against prédation, and that group size is influenced by risk of perception.

This study analyses differences in European rabbitOryctolagus cuniculus (Linnaeus, 1758) abundance between fragmented and continuous populations and the relative importance of habitat structure (micro- and macrohabitat) and isolation in determining the abundance pattern in fragmented and continuous areas of central Spain. The species was mainly restricted to mediterranean vegetation habitat. In fragmented areas, rabbit abundance was linked to scrubland cover but was not correlated to pasture/cropland cover. The model explained very little of the observed variance. Distance to continuous populations did not improve the model. Stochastic phenomena or unmeasured factors (predation level, soil type) could be acting in this context. Rabbits were more abundant in continuous areas than in fragmented ones. In continuous areas, rabbit abundance was associated with mosaics of pastures, scrublands, and croplands. These habitat features are linked to shelter and feeding requirements of rabbits. The model explained an important part of the observed variance. This supports that management and conservation strategies should be based on the landscape pattern in each situation.

Seasonal foods of European rabbits Oryctolagus cuniculus (Linnaeus, 1758) were studied by microhistological analysis of pellets in a protected area Bugac Juniper Forest, Hungary. Field experiments were also conducted to examine the role of rabbit foraging on common juniper Juniperus communis. The proportion of grasses, forbs and browses changed significantly throughout the seasons (p < 0.0001). Spring diet was dominated by grasses (89%), summer diet by grasses (30%) and forbs (42%), whereas in autumn grasses (60%) and browse (24%) were the main diet components. Juniper appeared only in winter diet (19%) together with other browse (60%). The high proportion of aromatic thyme Thymus glabrescens in summer diet (30%) and juniper in winter diet indicates that monoterpenoids of these plants did not keep rabbits from consumption even when other food sources were available. Planted juniper seedlings disappeared within weeks due to the browsing by rabbits.
