- Abstract:
- ... Iran is a mountainous country. Zagros and Alborz mountains reach altitudes of more than 4,000 m. Alpine regions are above timber-line, which is not easy to recognize, since aridity is prominent in most regions. The alpine zone in Alborz lies between 3,000 and 4,000 m, the nival zone is above 4,000 m, locally varying by some hundred meters. A first evaluation of vascular flora shows that 682 specie ...

- Abstract:
- ... Since the coining of the term, biodiversity has come to be understood as being more than a synonym for species richness. It also embraces a diversity of lifestyles, so that of two samples with the same number of species one that solely comprises a diversity of herbivores is considered to be less biodiverse than one that includes detritivores, predators, parasitoids, parasites, etc. as well. It see ...

- Abstract:
- ... We conducted a prioritization exercise for 47 terrestrial carnivores in North and Central America. We used 2 by 2 degree cells to explore the spatial patterns in overall richness, regionally endemic and threatened species and identified the hotspots (the top 10% of cells in each category). We obtained optimal minimum sets of cells to represent each carnivore either (1) at least once, (2) three tim ...

- Abstract:
- ... The knowledge of the areas inhabited by a species within its distribution range and the connections among patches are critical pieces of information for successful conservation actions. The internal structure of the extent of occurrence (EO) of a species is almost always unknown, even for “well-known” flagship species. We developed a methodology to infer the area of occupancy (AO) within the EO of ...

- Abstract:
- ... Due to ubiquitous eutrophication and fragmentation, many plant species are actually threatened in Europe. Most ecosystems face an overall nutrient input leading to changes in species composition. Fragmentation is effectively influencing species survival. We investigate if two different measures of species performance of 91 calcareous grassland species-rate of decline and rarity--are related to com ...

We report the establishment of the first in situ collection of beneficial symbiotic microorganisms (arbuscular mycorrhizal fungi) in the world, located in an integrally protected area of coastal sand dunes, within the UNESCO Biosphere Reserve “Selva Pisana”, in Tuscany, Italy. In this collection the genus Scutellospora, which has been reported to be threatened by anthropogenic disturbance, was a r ...

Eight groups of hindrances in evaluating the global conservation status of threatened taxon are identified: (1) the extreme heterogeneity and (2) restricted availability of relevant data; (3) the uncertaint ...

- Abstract:

Red deer (n = 149) from eight geographical locations, including the endangered endemic populations from the Tyrrhenian islands (Sardinia and Corsica), were analysed at eight polymorphic microsatellite loci. Two questions were addressed: (1) Is there a founder effect in the Corsican population, which was reintroduced to the island using Sardinian deer after the species' extinction on Corsica? (2) W ...

- Abstract:

Species-area and species-area-habitat relationships are analysed using the classical species-area model and the recently proposed species-choros model. The number of floristic zones (used to estimate the choros parameter) provides an adequate estimate of the potential habitat diversity, an ...

Over recent decades wild rabbit populations have undergone a sharp decline in Spain with consequent negative impact both on a game-based economy, and on the conservation of threatened species that depend on rabbits. We investigated the relationships between rabbit population change and habitat and game management in central-southern Spain. To determine recent rabbit population changes we revisited ...

- Abstract:
- ... Many insects living in ancient trees are assumed to be threatened as a result of habitat loss and fragmentation. It is generally expected that species in habitats with low temporal variability in carrying capacity have lower degree of dispersal in comparison to those in more ephemeral habitats. As hollow trees are long-lived, species in that habitat are expected to be sensitive to habitat fragment ...

In order for these systems to be successful, however, they must address real-world management problems with input from both the scientific and management communities.

Within six plots of 4.82 ha in total, we found 42 rattan species in six genera with 4,736 stems (>=20 cm long). There was a significant positive correlation between rattans and trees in species diversity, decreasing in the order mixed dipterocarp (for rattans: ...

The process of selecting candidate areas for inclusion in a regional conservation network should include not only delineating appropriate land units for selection and defining targets for representing features of interest, but also determining the suitability of land units for conservation purposes. We developed an explicit rating of conservation suitability by applying fuzzy-logic functions in a ...
