Semi-structured interviews and participant observation were used to understand how urban Chileans form relationships with nature and nonhuman species in central Chile. Most informants expressed dislike of the typical mediterranean-habitat landscape, characterizing it as dry, poor, and empty. Yet many people expressed nostalgic attachment to specific places, species, and activities that they had experienced, often as children. Most of the reminisced-about interactions were fleeting or had been lost over time. In the dominant discourse, nature in the mediterranean zone of Chile is closely associated with poverty, and it is considered to lack beauty, biodiversity, culture, and history. Appeals to personal nostalgia may break through this discourse to form private assemblages of value. Chileans also attributed social value to interactions with species who are rare or who are found “exclusively” in Chile. Appeals to nostalgia, rarity, and exclusivity help to draw these private discourses into the public realm.

Acorn Removal

The seed fate in early successional habitats can determine plant composition and regeneration capacity after disturbance. Predispersalseed removal has been poorly studied in Mediterranean habitats, especially in burned and logged habitats. We assessed it for two years in pine forests with experiments excluding vertebrates from fleshy fruits (infructescences of Smilax aspera and Rubia peregrina) and acorns (branches of Quercus coccifera). We compared one unburned and one burned area (control). Acorn removal was nil in the burned area while in the unburned habitat seed removal occurred from the beginning of the experiments. It is suggested that the greater vegetation cover in the unburned area shelter rodents from predators and increased their activity. In contrast, reduced cover in the burned area and the occurrence of gnawed acorns on the ground suggest acorn removalby rodents mainly in the post-dispersive stage. Smilax aspera seed removal was slower, and total loss of fruits due to senescence higher,in the burned area. Seed removal appears to be conditioned by interannualvariations related to the activity and density of granivores and frugivores, the availability of fleshy fruits, and the maturation of fruits.In post-fire managed areas the role of granivores and frugivores in the regeneration process should be taken into account.

The intent of this work is to summarize the available knowledge on the appearance, identification and distribution of Cuvier's beaked whales (Ziphius cavirostris) in the Adriatic Sea through a review of historical data, inspection of natural history collections and collection of original data. In total, eleven occurrences are documented of Cuvier's beaked whale along the Adriatic coast with all records originating from the deep southern Adriatic basin. The number of recorded stranded Cuvier's beaked whales in the southern Adriatic represents about 3% of the recorded specimens in the entire Mediterranean. This percentage increases up to about 5% when considering only data collected after the first recorded stranding of the recent era in 1975. Comparing these percentages to the extent of the area relative to the Mediterranean, the proportion of occurrence of the total stranded Cuvier's beaked whales in the southern Adriatic ranged between the same to double of that of the entire Mediterranean Sea. Therefore, the southern Adriatic Sea should be considered as a potentially relevant habitat of the Cuvier's beaked whale. This hypothesis has clear conservation implications particularly in view of the adverse impact of sonar experiments, carried out by navies from several countries, on this species and should be further investigated. Finally, there is no evidence of the northern bottlenose whale (Hyperoodon ampullatus) ever having occurred in this part of the Mediterranean region.

AbstractTwo weevil species, Ceutorhynchus geographicus (Goeze) and C. larvatus Schultze, feed on Echium plantagineum (Boraginaceae) in southern France. This paper shows that they do not compete for resources in the host's native environment. Niche overlaps of the two weevils were measured using the proportional overlap measure and Morisita's original index. The two species showed significant overlap in niche requirements during the egg and early larval stage. During the final two larval instars, larvae feed on different parts of the plant, C. geographicus in the tap root and C. larvatus in the root crown. Spatial separation in niche requirements is augmented by a temporal separation, C. larvatus emerging in the field about one month earlier than C. geographicus. In Europe and in Australia, to which E. plantagineum has been introduced and has become a serious weed, the host-plant has an extended germination period during the autumn. The differences in emergence times of the two species mean that their niches are separated both in time and in space. Should the two species be released into Australia they would not compete for resources. They may, however, be able to displace other species of the stemfeeding guild that are also proposed as candidates for the biological control of E. plantagineum.

Management Algorithms

Management algorithms of protected areas are widely used to identify potential networks of natural reserves that meet pre-established ecological requirements, such as a specific habitat percentage or a specific number of populations, while minimizing the related costs. Here we present a comparison of priority conservation maps of a protected area in central Italy, generated using different methods (i.e., Marxan, Marxan with Zones, Zonation, and directly overlapping the bird data with the vegetation type in the study area), based on an eight-year data set describing bird communities in the Circeo National Park. The generated maps can be used as a starting point when working with stakeholders involved in the management of this area. Our cartographic comparison illustrated that in the majority of the cases priority areas overlapped (the proportion of overlap was greater than 80% of the area size), affirming that the methods are equivalent. However, there were also divergent cases (the proportion of overlap was 0% of the area size), suggesting differential sensitivities of the four compared methods.

Tetrao Urogallus Cantabricus

SummaryNature reserves focused on the protection of an endangered species are often restricted to the core of the species’ distribution, leaving peripheral populations unprotected due to a lack of specific knowledge. This study describes the factors that potentially contribute to degradation of habitats of a peripheral population of the endangered Cantabrian Capercaillie Tetrao urogallus cantabricus. Using presence/absence data, we compared forest fragmentation, fire risk, and distance from leks to human infrastructure. Forest fragments in which Cantabrian Capercaillie were detected were significantly larger, closer to the nearest occupied fragments, and had a higher proximity index than fragments in which no presence was detected. Eighteen percent of the area of fragments in which Cantabrian Capercaillie presence was detected were placed in the high risk of fire category. Human infrastructure represents a permanent loss of Mediterranean habitat for the Cantabrian Capercaillie. The study area is highly modified by human activities; a priority conservation measure should be inclusion within the Natura 2000 network.
