The Helminth Community of the Red Fox, Vulpes Vulpes , In Dunas de Mira (Portugal) and its effect on host condition
The analysis of 62 foxes collected by hunters between 2000 and 2006 revealed that the helminth community of the red fox in Dunas de Mira is composed by 20 species, and the component species are discussed considering the redfox diet in the study area, their relationship with a lowered host condition and their possible transmission to humans.

Site occupancy provides a reasonable estimate of population status and trends, and it also provides an unbiased, cost-effective alternative method for large-scale, multispecies monitoring programs.…
Ecological aspects influencing the helminth community of the wood mouse Apodemus sylvaticus in Dunas de Mira, Portugal
The first extensive data on the helminth community of the wood mouse Apodemus sylvaticus in a coastal sand dune area in Portugal is presented, with some differences in prevalence and mean intensity values found in relation to year, habitat and season.
Concentration of some toxic elements in Oryctolagus cuniculus and in its intestinal cestode Mosgovoyia ctenoides, in Dunas de Mira (Portugal).
Spatial colonization by feral domestic catsFelis catus of former wildcatFelis silvestris silvestris home ranges
The need for urgent measures aimed at preserving wildcat populations should include a national census of the species and an extensive monitoring of genetic integrity of wild cat populations, followed by the elaboration of a wildcat conservation action plan.
Helminth species richness in wild wood mice, Apodemus sylvaticus, is enhanced by the presence of the intestinal nematode Heligmosomoides polygyrus
Results support those of Behnke et al. (2005), providing firm evidence that at the level of species richness a highly predictable element of co-infections in wood mice has now been defined: infection with H. polygyrus has detectable consequences for the susceptibility of wood mice to other intestinal helminth species.

Since metal levels showed a consistent pattern in feathers and excrements of nestling great tits, it is concluded that both represent good and non-invasive methods for the evaluation of these elements in polluted areas.
Evaluation of Camera Trapping for Estimating Red Fox Abundance
Estimating red fox density in Serra da Malcata, Portugal is possible to define the number of foxes that must be sampled to assess the presence of potential fox-transmitted diseases that may affect lynx reintroduction.

Positive linear relationships were detected among kidney, liver, and muscle, with emphasis on relationships involving Cd, Hg, Se, and Zn, which may be indicative of analogous regulation mechanisms in those organs.
