Reproductive ecology ofAsclepias meadiiTorr. ex A.Gray (Apocynaceae), a federally threatened species

Français. Un inventaire des ptéridophytes a été entrepris dans les forêts de la région de Tlemcen. L’inventaire de ces populations constitue une étape importante pour le développement des stratégies de conservation des ressources génétiques et de la diversité de ces populations sur l’ensemble de leur aire de distribution naturelle. Nous avons ainsi effectué le recensement et l’identification des fougères existantes dans la région de Tlemcen. Au total, plusieurs stations dont les caractéristiques écologiques diffèrent d’un site à un autre ont été prospectées, cela a permis l’identification de 26 taxons (dont 5 exceptionnellement rare). La création de réserves naturelles forestières renforcée par une protection réglementaire des espèces les plus menacées est nécessaire pour le maintien de ces communautés si particulières. English. An inventory of Pteridophyta was begun in the forests of the Tlemcen region. The inventory of these populations constitutes an important stage for the developement of the strategies of preservation of the genetic resources and the diversity of these populations on their whole area of natural distribution. We so made the inventory and the identification of the existing ferns in the region of Tlemcen. On the whole, several stations the ecological characteristics differ from a site in the other one were canvassed; they allowed the identification of 26 taxes (among which 5 exceptionally rare). The creation of forest nature reserves strengthened by a statutory protection of the most threatened species is necessary for the preservation of these particular communities.

Definition Of

In the red list of threatened species of Pará State, in Brazil, the salamander Bolitoglossa paraensis was listed as vulnerable. Initially the species was considered a synonym with Bolitoglossa altamazonica, but was recently revalidated. This note discusses the validity of the specimens from the west of the Brazilian Amazon identified as B. paraensis. It is also discussed the categorization of the species as vulnerable, and the records of the species was mapped in the Endemism area Belém. In order to establish a Private Natural Reserve (RPPN), a herpetological survey was carried out in different landscape units of the Nova Amafrutas, in Benevides (Pará), and the records of B. paraensis were mapped in these landscape units. By comparing the abundances recorded by Crump (1971) and those results of the present study, suggested that this species is tolerant to antropic “capoeira” forest (old fallows) next to undisturbed forest. More molecular phylogeographic studies are needed in order to establish a stable the taxonomy status for B. paraensis, and also the definition of its real endemic status in the Center of Endemism of Belém.
