A new aetosaur from the Upper Triassic of the Santa Maria Formation, southern Brazil.
A new Late Triassic juvenile aetosaur from the Santa Maria Formation of southern Brazil is described, increasing the paleobiodiversity of this interesting group to five taxa in Western Gondwana.

An ecomorphological analysis employing dental traits indicates that herrerasaurids occupy a particular area in the morphospace of faunivorous dinosaurs, which partially overlaps the area occupied by post-Carnian theropods, indicating that her rerasaurid dinosaurs preceded the ecological role that later would be occupied by large to medium-sized theropoda.
A new Permian temnospondyl with Russian affinities from South America, the new family Konzhukoviidae, and the phylogenetic status of Archegosauroidea
This taxon is considered to be a nomen dubium and purge it from the strict consensus tree, and the phylogenetic results support the erection of a new family – Konzhukoviidae – to replace ‘Tryphosuchinae’ and accommodate Konz hukovia vetusta, K. tarda and K. sangabrielensis, the new Brazilian species basal to the Russian forms.
New postcranial elements of the Thalassodrominae (Pterodactyloidea, Tapejaridae) from the Romualdo Formation (Aptian–Albian), Santana Group, Araripe Basin, Brazil

New postcranial material from the Romualdo Formation (Aptian–Albian) from the Araripe Basin is described, which is the most complete postc Cranial material assigned to the Thalassodrominae described so far.
The rocky intertidal plankton trap RIPT2: A modified device
The modification (RIPT2) of an earlier described, passive Rocky Intertidal Plankton Trap to be used in exposed rocky shores is described, which aims to evaluate and integrate over time the mero- and holoplankton arriving to the rocky shore.

This chapter discusses the development of paleontologia in the 19th Century and its role in the evolution of science and medicine.
Marine Biodiversity of Eastern Tropical Pacific Coral Reefs
The eastern tropical Pacific (ETP) is an isolated oceanic region exposed to extreme oceanographic conditions, including low salinity, low pH, high temperatures during El Nino, and low temperatures…

The present and previous studies show that the general shape of the functional response in shorebirds eating approximately the same size of prey across the full range of prey density is a decelerating rise to a plateau, thus approximating the Holling type II (‘disc equation’) formulation.

The second known specimen (CAPPA/UFSM 0123) of Prozostrodon brasiliensis is described, showing that the adult individual has more postcanine tooth morphotypes than the juvenile one.
Patch recolonization by the tunicate Pyura praeputialis in the rocky intertidal of the Bay of Antofagasta, Chile: evidence for self-facilitation mechanisms

Patch dynamics of intertidal Pyura praeputialis were studied and it is believed that the mech- anism of recolonization is most probably related to the settlement of recruits to the border of previ- ously settled individuals, possibly mediated by intraspecific self-facilitation mechanisms.
