Detecting a Stalker: The Effect of Body Posture, Gaze Direction, and Camouflage Pattern on Predator Detection.

The success of a predatory attack is related to how much a predator manages to approach a prey without being detected. Some carnivore mammals use environmental objects (e.g.

Using biodiversity databases to assess vascular plant diversity in Protected Areas: a case study of Parque Estadual do Forno Grande, Brazil.

Background: The Parque Estadual do Forno Grande is a fully protected area in the southern Espírito Santo State, Brazil. It belongs to the Atlantic Forest domain, with predominantly dense, ombrophilous, seasonal semi-deciduous forests and herbaceous/shrubby vegetation on rock outcrops. The area is recognised as highly important for conservation, designated as a priority biological area for protecting the Atlantic Forest's biodiversity.

Comparison of postoperative outcomes between different dissection techniques during laparoscopic cholecystectomy in rabbits: randomized study.

Purpose: Laparoscopic cholecystectomy (LC) is the gold standard for the treatment of gallbladder (GB) disease in small animals. The aims of this study were to investigate and compare the effect of different types of dissectors during LC in rabbits; electrothermal bipolar vessel sealing device (EBVS-LigaSure) and standard electrosurgical dissection (bipolar Maryland) for dissection of the GB in LC, correlating liver function tests (LFTs) in pre and postoperative periods (days 0, 3, 7, 15); macroscopic checking 15 days after surgery through necropsy; histopathological, bacteriological through bacterial growth by culture and intraoperative complications.

Methods: Twenty rabbits were used, group (n = 10) using EBVS for GB dissection and cystic duct seal (GLL), and group (n = 10) using bipolar dissecting forceps and EVBS for cystic duct seal (GLE).

Floristic survey of vascular plants of the Parque Estadual da Pedra Selada, Rio de Janeiro, Brazil.

Background: The Atlantic Forest is one of the most diverse and threatened phytogeographical domains in the world. Despite that, it includes regions with poor floristic knowledge, even in protected areas. Although the importance of protected areas in conserving the Atlantic Forest hotspot is undisputed, it is necessary to recognise the floristic richness of these areas to propose effective conservation actions.

A comprehensive floristic knowledge of a fragment of Semideciduous Seasonal Forest [Parque Estadual da Serra da Concórdia], Rio de Janeiro, Brazil.

Background: The "Serra da Concórdia" is part of the Atlantic Forest phytogeographical domain in the Brazilian state of Rio de Janeiro and it has a predominant phytophysiognomy of Semideciduous Seasonal Forest. This region underwent intense habitat loss and fragmentation during the 19 century, due to coffee plantations and later pastures. With the decline of these activities, the areas were abandoned, triggering secondary succession.
