On the basis of previous observations, the critically endangered western ringtail possum (Pseudocheirus occidentalis) has been described as strictly arboreal. Using motion-sensing cameras placed in bushland remnants and residential gardens, we demonstrate that the species uses the ground during its nocturnally active period. To acknowledge that ground use may make the species more susceptible to terrestrial predators than previously thought, we propose that the species should not be described as ‘strictly’ arboreal.

The Nile soft-shelled turtle (Trionyx triunguis) is distributed between Dalyan and Samandağ throughout the Mediterranean coast in Turkey. The Mediterranean subpopulation of the Nile soft-shelled turtle is listed as critically endangered in the IUCN Red List Categories. This investigation aimed to determinate levels of genetic variations and patterns of genetic structures among Mediterranean populations in Turkey by using T. triunguis-specific microsatellite primers. A total of 13 polymorphic microsatellite loci were studied among samples of 121 individuals collected from five populations in Turkey. Of 13 polymorphic microsatellite loci used, 3 new were identified in this study. The genetic differentiation among the 5 studied populations of T. triunguis was significant (p 0.001). The analysis of molecular variance (AMOVA) indicated that genetic variations occurred mainly within populations (89.7%) rather than among populations (10.3%). Structure analysis showed presence of two main groups among the Mediterranean T. triunguis populations. However genetic variations among populations were not correlated with geographic distance between the locations. Analysis of data showed that one of the populations (Dalyan) had undergone a bottleneck effect. Migration analysis indicates that T. triunguis migrates between five Mediterranean populations in Turkey. We concluded that based on our results the status of ‘critically endangered’ of T. triunguis should be maintained. Long term population genetic survey studies should be undertaken and changes in habitats of T. triunguis populations, as well as their population size and structure should be monitored for each population to be able to establish a clear strategy for protection of T. triunguis.

A New Species

Silene lulakabadensis Heidari, F. Ghahrem. & Assadi is described as a new species from Zanjan Province, Iran. The new species is a dark green plant, perennial and woody at the base, that was collected on marl soil slopes at 2100 m. It is believed to be closely related to S. eriocalycina Boiss. from section Auriculatae (Boiss.) Schischk. but is a smaller plant, with much shorter internodes, and pinkish-white retuse to emarginate petals with very small or no scales. It is a very rare plant and its conservation status is assessed as Critically Endangered.

Risk Of Extinction

Cyprinid fauna endemic to the Iberian Peninsula is currently facing several human-caused threats which enhance their risk of extinction. The populations of the critically endangered Achondrostoma occidentale, occurring only in three small and intermittent Portuguese river basins, have been reinforced with fish bred ex-situ in order to minimize their risk of extinction. This study aimed to describe the restocking actions conducted and to identify and characterize the summer refugia that should become targets for restoration and further restocking. The results evidence population increments and a high representativeness of younger age classes in the restocked populations. The importance of annual monitoring of fish abundance to assess how the species is coping with the stochastic and deterministic stressors that may eventually compromise its survival is highlighted.
