The Iberian Peninsula is a repository for biodiversity, presenting high levels of endemism in both plants and animals. In this peninsular region, brook lampreys confined to small, isolated river basins evolved in allopatry giving rise to evolutionary lineages, as revealed by mitochondrial DNA markers. For a better understanding of the taxonomic status and relationships of Iberian populations of the genus Lampetra, we combined previous data from genetics and morphological analysis (assessed here), and describe three new species of the lamprey genus Lampetra Bonnaterre, 1788 in Portugal. In this region L. planeri actually represent a complex of cryptic species, each having smaller geographic ranges than L. planeri, and consequently, greater vulnerability to... |

In response to predation pressure by raptors, snakes, and carnivores, primates employ anti-predator behaviours such as avoiding areas of high predation risk, cryptic behaviour and camouflage, vigilance and group formation (including mixedspecies associations), and eavesdropping on other species’ alarm calls. After detecting a predator, primates can produce alarm calls, show predator-specific escape strategies or even mob the predator. It remains unclear how solitary nocturnal primates respond to diurnal predation pressure while they sleep or rest. The aim of this study was to investigate the diurnal anti-predator behaviour of the nocturnal and solitary Sahamalaza sportive lemur, Lepilemur sahamalazensis, which regularly rests in exposed locations. We... |

Two new paniculate species of Nepenthes, N. halmahera and N. weda, both allied to N. danseri Jebb & Cheek, are described respectively from lowland and lower montane forest on ultramafic substrate. Nepenthes weda appears to be unique in the genus due to the adaxial tepal surfaces which in the distal portion are hairy and lack nectar glands. This species is also unique among paniculate members of the genus in its forward-facing, concave subapical lid appendage. Both species are currently only known from the Weda Bay Nickel Project concession area in Halmahera, Indonesia, and are assessed as Critically Endangered using the 2012 IUCN standard. Two character states are formally described and named for the first time in Nepenthes: nanophyll rosettes and... |
