Lateralized behaviour has been studied as an observable measure of cerebral functional asymmetry for many years, and interest in the evolutionary origins of lateralized behaviour in humans has prompted research into the study of manual laterality in nonhuman primates. The Sichuan snub-nosed monkey (Rhinopithecus roxellana) is a rarely studied species as far as laterality research is concerned. ...

The morphology of the final phyllosoma larval stage of the slipper lobster Scyllarus pygmaeus is described and illustrated based on larvae captured from Mediterranean waters and compared with those described in other Scyllaridae. These larvae were always found in deep waters (.200 m). Nucleotide sequence analysis of a region of the nuclear 28S rDNA gene identified these larvae as S. pygmaeus, t...

Cryptosporidium sp. is a zoonotic intestinal protozoa in orangutans which transmitted through contaminated water (waterborne disease). This study aims to determine infects the sumatran orangutan (Pongo abelii) and bornean pygmaeus) North Sumatera Wildlife Park. The samples used were 3 fecal from different locations, two Medan Park one Pematang Siantar Animal Samples examined using floatation me...

PREMISE OF THE STUDY Simple sequence repeat (SSR) markers were developed for Aster savatieri (Asteraceae) and the serpentine variety A. savatieri var. pygmaeus to re-evaluate their taxonomic status. METHODS AND RESULTS Using RNA-Seq data, 22 expressed sequence tag (EST)-SSR markers were developed. Polymorphisms were assessed in A. savatieri and in A. savatieri var. pygmaeus. The average numbe...

The courtship behaviour of pygmy newts, Triturus pygmaeus, consists of three phases: orientation, static display (often not clearly differentiated from each other) and spermatophore transfer. The repertoire of male sexual behaviour consists of nine different movements. Exhibition, an alert posture in which the male advances with small jumps around the female, is the most frequent behaviour. The...
