Phreatobius sanguijuela Fernandez, Saucedo, Carvajal-Vallejos & Schaefer, 2007, new species
No full text[[Phreatobius sanguijuela new species]] Note added in proof Subsequent to the correction of proofs for this paper, we became aware of the publication of a new Brazilian species of Phreatobius (Shibatta et al., 2007). The new Brazilian species is apparently not conspecific with the Bolivian species described here, based on the following differences: total vertebrae 45-46 (versus 48-49) [note: reported data for the Brazilian species is adjusted to correspond with our method for counting vertebrae]; 14-16 ventral procurrent caudal-fin rays (versus 11-13); 4 pectoral-fin rays (versus 5); first anal-fin pterygiophore on vertebra 18 (versus 16-17).

Intraguild interactions among generalist predator functional groups drive impact on herbivore and decomposer prey
No full textSanders D, Schaefer M, Platner C, Griffiths GJK. Intraguild interactions among generalist predator functional groups drive impact on herbivore and decomposer prey. OIKOS. 2011;120(3):418-426.We found no positive effect of increasing predator functional group richness on prey control. However there was evidence for strong composition effects between the functional groups. The presence of ants in predator assemblages reduced the prey suppression through mostly trait-mediated intraguild interactions, while hunting and web-building spiders contributed additively to prey suppression and reduced the density of herbivore and decomposer prey by 50-60%. A trophic cascade on plant biomass triggered by web-builders and hunting spiders was diminished at levels of higher predator group diversity.In conclusion, our experiments showed that intraguild interactions strongly influence the strength of top-down control by generalist predators. Among spiders there was evidence for a positive relation between functional group richness and prey suppression but the overall outcome strongly depended on the occurrence of interference, driven by trait-mediated indirect interactions
