Zur Ultrastruktur der seitlichen Sinnesorgane am Augenhügel vonAnoplodactylus pygmaeus (Pycnogonida)
The genus Fluviphylax Whitley, 1965is comprized of five valid species (Fluviphylax pygmaeus Myers et Carvalho, 1955, Fluviphylax zonatus, Fluviphylax simplex, Fluviphylax obscurus Costa, 1996,and Fluviphylax palikur Costa et Le Bail, 1999), which are endemic to the Amazon region. These fishes are the smallest known South American vertebrates and among the smallest know vertebrates on Earth. All...
A new species of Anoplodactylus was discovered in coral reefs from the State of Paraíba, northeastern Brazil. A. mirim sp. nov. is very small and is characterized for having 3 teeth on the cheliphores and a very small cement gland. It belongs to the A. pygmaeus complex, which contains very small species. A. batangensis is recorded for the first time along the Brazilian coast, and A. eroticus is...
Sample collection A list of individuals, origins and hybridization arrays can be found in Supplementary Table S11. The geographical origins of the ancestors of our samples are sometimes unavailable. Gathering all possible information, we could determine that, among the individuals used on the oligonucleotide array, 5 chimpanzees are Central chimpanzees (Pan troglodytes troglodytes), 1 is a West...
Piagetian liquid conservation in the great apes (Pan paniscus, Pan troglodytes, and Pongo pygmaeus).
An understanding of Piagetian liquid conservation was investigated in 4 bonobos (Pan paniscus), 5 chimpanzees (Pan troglodytes), and 5 orangutans (Pongo pygmaeus). The apes were tested in the ability to track the larger of 2 quantities of juice that had undergone various kinds of transformations. The accuracy of the apes' judgment depended on the shape or number of containers into which the lar...
Performance on identical search tasks based on cues directly perceived or indirectly perceived through video were compared among a group of 4 adult chimpanzees (Pan troglodytes), a group of 2 adult orangutans (Pongo pygmaeus), and a group of 36 children (between 2 and 3 years of age). Children comprehended directly perceived cues but had difficulty with video cues. In contrast, chimpanzees and ...
Sequences totaling 3,500 bases from the 28S rRNA gene and from one of the ribosomal internal transcribed spacers (ITS1) have been determined for human, chimpanzee (Pan troglodytes), gorilla (Gorilla gorilla), and orangutan (Pongo pygmaeus). Analyses of the rRNA alignments show (1) a clustering of substitutions in the "variable regions" of the 28S gene, (2) a 1.5-3-fold increase in divergence in...
