In Madeira, around 36% [10] and in the Azores, around 70% species are exotic. [11] [12] Due to this, Portugal was placed 168th globally out of 172 countries on the Forest Landscape Integrity Index in 2019. [13] Chameleo from Algarve. Portugal is the second country in Europe with the highest number of threatened animal and plant species (488 as ...
Stage 2 assesses the member country sites at a European Community level. It considers the national value of the site, its size and biodiversity, whether it is part of a continuous ecosystem on both sides of a frontier between member states, and its global ecological importance for its biogeographical region.
Megadiversity means exhibiting great biodiversity. The main criterion for megadiverse countries is endemism at the level of species, genera and families. A megadiverse country must have at least 5,000 species of endemic plants and must border marine ecosystems.
With a world-average biocapacity of 1.63 global hectares (gha) per person (12.2 billion in total), this leads to a global ecological deficit of 1.1 global hectares per person (10.4 billion in total). [ 1 ]
The Protected areas of Portugal (Portuguese: Áreas protegidas de Portugal) are classified under a legal protection statute that allows for the adequate protection and maintenance of biodiversity, while providing services for ecosystem that maintains the natural and geological patrimony.
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time.Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. [1]
A variety of objective means exist to empirically measure biodiversity. Each measure relates to a particular use of the data, and is likely to be associated with the variety of genes. Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness ...
