“…It is important to point that even for species widely distributed in the Atlantic Forest, such as P. corcovadense, P. cordatum and P. crassinervium, the regional status based on geographic distribution suggests these taxa as threatened in the state of Rio de Janeiro. Our work reinforces the need for regional lists for effective conservation practices (Gärdenfors et al 2001).…”

“…The AOO and EOO indexes refer to the distribution of a taxon in a given region: EOO corresponds to the area contained within the smallest convex polygon that can be drawn to include all known sites of occurrence of a taxon; AOO corresponds to the effective area within the EOO which is actually occupied by a taxon (IUCN 2010). This approach allowed us to assess conservation status at a regional level (Gärdenfors et al 2001) by applying IUCN (2010) assessment criteria, restricted to the state of Rio de Janeiro in this case. Each species was evaluated based on all the points surveyed for the state (List S1 in supplementary material), considering first the occurrence in Grumari restinga and then excluding it.…”

Th is study surveyed species of the family Araceae in Grumari restinga, located in the metropolitan region of the city of Rio de Janeiro, Brazil. We aimed to: i) eva luate the contribution of a single locality (Grumari restinga) to regional conservation (Rio de Janeiro State) of Araceae; and ii) compare the distribution of species of Araceae among restingas of the state. We calculated the extent of occurrence and the area of occupancy in the entire state for eight species of Araceae found in Grumari,and performed a similarity analysis among restingas. Our data de monstrate that the extent of o ccurrences for Anthurium augustinum, A. coriaceum and A. maricense are infl uenced by Grumari because this area is the boundary of their known distribution in the state. Grumari did not have an infl uence on the distribution of the other studied species. We found Anthurium coriaceum, A. luschnathianum and Philodendron crassinervium to exhibit unusual habits as terrestrial plants in sandy soil. Th e similarity analysis identifi ed six groups of Araceae, four of which are related to the distance from adjacent forests. We demonstrated that this small conservation unit represents a key locality in the preservation of natural populations of species of Araceae in Rio de Janeiro State.

“…Thus, the species as a whole is classified as Least Concern globally, however, there are really endangered points in its habitat within some regions. When the global category is not the same as the national or regional category, the cases like this are defined in the literature, for example in (Gärdenfors et al 2001).…”

BioRisk 6: 41-60. doi: 10.3897/biorisk.6.1568 AbstractRepresentatives of the resurrection plants from Gesneriaceae family are included in the Red Book of Bulgaria, in the European Register of rare, endangered, and endemic plants, and are subjects of world's conventions on the preservation of the biodiversity. The unique feature of these plants to recover from prolonged dehydration (anabiosis) is explored in numerous studies. These species are also Tertiary relics, so they could give us important knowledge about plant evolution.Our research group at the University of Plovdiv has established a national in vitro gene bank for Haberlea rhodopensis Friv. (25 localities) and Ramonda serbica Panc. (2 localities) from Bulgaria. The national gene bank is based on original and modified in vitro technologies and can serve as a conservation and biodiversity investigation center for the family Gesneriaceae.Basing on our work with Haberlea rhodopensis Friv., we are developing a strategy for conservation and investigation of rare and relic plant species (mapping and exploration of habitats -assessing the local risk of extinction -introducing in an in vitro gene bank -model plants for research -adaptation and possible reintroduction in endangered habitats). This strategy can be adapted and used for conservation and investigation of other rare, protected, relic and endemic plants from other regions of Europe and worldwide.

“…Se basa en cuatro medidas principales concretas: 1) disminución poblacional en el tiempo; 2) área de distribución/ocupación; 3) tamaño poblacional; y 4) análisis cuantitativo de la probabilidad de extinción. No obstante, tales criterios también suelen utilizarse para calificar el índice de amenaza de las especies a escala regional, utilizando modificaciones y adecuaciones de los criterios previos y sus valores umbrales (Gärdenfors, 2001;Gärdenfors et al, 2001). Esta práctica ha sido utilizada en varios contextos nacionales (véase por ejemplo el Libro Rojo de las Aves de España; Madroño et al, 2004), aunque no está exenta de problemas debido a la subjetividad de su aplicación (Carrascal y Palomino, 2006 y referencias allí dadas), teniendo en cuenta el tamaño de la región analizada en relación con la extensión total del área de distribución de la especie, su posición geográfica dentro de ésta, la contribución de los efectivos poblacionales regionales al total mundial, provincianismo conservacionista, etc.…”
