Testing dietary hypotheses of East African hominines using buccal dental microwear data
Abstract There is much debate on the dietary adaptations of the robust hominin lineages during the Pliocene-Pleistocene transition. It has been argued that the shift from C3 to C4 ecosystems in Africa was the main factor ...
Influence of nitrate and ammonium availability on uptake kinetics of stream biofilms
Human activity has significantly increased dissolved inorganic N (DIN) availability and has modified the relative proportion of NO3− and NH4 species in many streams. Understanding the relationship between DIN concentration ...
Feromones: el paper de l'olor en la comunicació animal
Chemical perception is considered one of the first senses used as a communication system between living organisms. Such communication is based on the emission of signals between a sender and a receiver; if the communication ...
Microsatellite markers reveal shallow genetic differentiation between cohorts of the common sea urchin Paracentrotus lividus (Lamarck) in northwest Mediterranean
Temporal variability was studied in the common sea urchin Paracentrotus lividus through the analysis of the genetic composition of three yearly cohorts sampled over two consecutive springs in a locality in northwestern ...

Seasonal patterns op biomass variation of Ruppia cirrhosa (Petagna) Grande and Potamageton pectinatus L. in a coastal logoon
Coastal lagoons where salinity varies within a wide range during the year are colonized by euryhaline macrophytes which can develop extensive beds. Seasonal changes in biomass of Ruppia cirrhosa and Potamogeton pectinatus ...
Letter to the Editor: Comments on"A new method to estimate adult age-at-death using the acetabulum" (Calce, 2012)
In 2006, Rissech and collaborators proposed seven variables of the acetabulum (1, acetabular groove; 2, rim shape; 3, rim porosity; 4, apex activity; 5, activity on the outer edge of the rim fossa; 6, activity of the ...

Evaluating potential artifacts of tethering techniques to estimate predation on sea urchins
Measuring the strength of trophic interactions in marine systems has been central to our understanding of community structuring. Sea urchin tethering has been the method of choice to evaluate rates of predation in marine ...
