Factors Influencing Human Attitudes towards Wolves in Northwest Spain

Surveys have been used to study the current perception towards wolves by different stakeholders such as ranchers, landowners, hunters, experts in the field, and employees of the environmental administration in the provinces of Pontevedra and A Coruña, in the northwest of Spain. The main objective of this study is the evaluation and further discussion of the compensation offered to affected people for damages caused by wolf attacks and whether such compensations represent an improvement in the degree of tolerance towards these animals. Significant differences (p < 0.05) were found among the different sectors interviewed, with the hunters being the least tolerant sector, followed by ranchers. The number of attacks in the area was proven to influence their perspective toward wolves and the need for preventive measures. There was unanimity among hunters, ranchers, and locals, who do not consider the tools provided by the Galician administration sufficient to palliate the damages produced by wolves. However, 53.8% of ranchers, the group whose livelihood will most likely be affected by wolf attacks, and 60% of the wolf experts believe that compensation does not help to reduce tolerance towards wolves. Losing an animal makes people more likely to agree to the use of lethal and non-lethal methods

Plant species richness increases with light availability, but not variability, in temperate forests understorey

Abstract Background Temperate forest understorey vegetation poses an excellent study system to investigate whether increases in resource availability lead to an increase in plant species richness. Most sunlight is absorbed by the species-poor tree canopy, making the much more species-rich understorey species inhabit a severely resource-limited habitat. Additionally, the heterogeneity of light availability, resulting from management-moderated tree composition and age structure, may contribute to species coexistence. One would therefore expect that the diversity in the herb layer correlates positively with either the overall light availability, or the light heterogeneity, depending on whether resource availability or heterogeneity are more important drivers of diversity. To test this idea, we assessed variability of light conditions in 75 forest plots across three ecoregions with four different methods. Results We correlated these data with vegetation relevés and found light availability to be strongly positively correlated with understorey plant species richness, as well as with understorey cover. Light variability (assessed with two approaches) within plots was positively correlated with transmittance, but did not improve the relationship further, suggesting that the main driver of species richness in this system is the overall resource availability. Two of the three beech-dominated regions exhibited near-identical effects of light transmittance, while the third, featuring pine alongside beech and thus with the longest gradient of transmittance and lowest species richness, displayed a weaker light response. Conclusions While site conditions are certainly responsible for the trees selected by foresters, for the resulting forest structure, and for the differences in plant species pools, our results suggest that light transmittance is a strong mediating factor of understorey plant species richness
