Open AccessStability of the personal relationship networks in a longitudinal study of middle school students
The personal network of relationships is structured in circles of friendships, that go from the most intense relationships to the least intense ones. While this is a well established result, little is known ab...

Open AccessChimpanzees organize their social relationships like humans
Human relationships are structured in a set of layers, ordered from higher (intimate relationships) to lower (acquaintances) emotional and cognitive intensity. This structure arises from the limits of our cogn...

Open AccessBeyond Dunbar circles: a continuous description of social relationships and resource allocation
We discuss the structure of human relationship patterns in terms of a new formalism that allows to study resource allocation problems where the cost of the resource may take continuous values. This is in contr...

Open AccessDNA barcoding allows identification of undescribed crab megalopas from the open sea
Megalopas of 15 brachyuran crab species collected in the open sea plankton, and unknown until now, were identified using DNA barcodes (COI and 16S rRNA). Specimens belonging to the families Portunidae, Pseudor...

Open AccessEvolution of social relationships between first-year students at middle school: from cliques to circles
People organize their social relationships under a restriction on the number that a single individual can maintain simultaneously (the so-called Dunbar’s number, ~150). Additionally, personal networks show a c...

Accelerated invasion of decapod crustaceans in the southernmost point of the Atlantic coast of Europe: A non-natives’ hot spot?
Observations of previously unrecorded non-native species in the Gulf of Cadiz (Spain), situated between the Atlantic Ocean and the Mediterranean Sea, have accelerated since 1980, and increased rapidly in the p...
