A bioturbator is a biota that can change sediment either directly or indirectly through stirring particles and/or moving water. Changes in the sediment affect the resources that will affect the existence of other organisms. This paper aims to explain bioturbators and their roles as ecosystem engineers in coastal and marine environments. Bioturbators are classified into two main groups, namely reworking organisms and burrow ventilation organisms. Bioturbator affects the biogeochemistry of sediment and the sediment physical structure, both of which cause the formation of new habitats that can be used by other organisms. This, in turn, will affect the structure of the benthic community. It is necessary to understand how bioturbators work and how big their effect is so that they can be used for habitat conservation and restoration in the future.

Abstract:The concept of ecosystem engineering has catalysed novel approaches and models for non-trophic species interactions and ecosystem functions. Ecosystem engineers physically modify abiotic and biotic environments, thereby creating new habitats that can be colonized by a new suite of species. In the Peruvian Amazonas, we tested whether peccaries (Tayassuidae) function as ecosystem engineers by creating and maintaining wallows. Such wallows could be critical aquatic habitats and breeding sites for anuran species during dry seasons. We compared hydroperiods of 21 peccary wallows and 13 naturally formed ponds across three dry seasons and found that wallows had a consistently higher mean water surface area than ponds. We also examined the pH, dissolved oxygen and temperature, and found no significant differences in these parameters between water bodies. Wallows had a significantly higher density of tadpoles, metamorphs and adult anurans, as well as higher β-diversity and species richness than ponds. This study not only provides the first systematic evidence of the ecosystem engineering processes of peccaries, but also reveals the positive consequences of such for anuran species.

Few studies have been reported of the effects of power-plant discharges on tropical and semi-tropical marine environments where plants and animals in non-stressed conditions live close to their upper lethal thermal limits. This paper describes a multidisciplinary three-years' study made in Card Sound, Florida, before, during, and after, thermal effluents were released from a power-plant. Biomass, growth, and production, of Thalassia and macroalgae, were estimated. Animals were collected by trawl, drop-net, suction dredge, in artifical habitats, and on mesh-panels. Except in an area of 2–3 ha adjacent to the canal mouth, little damage to the benthic community was observed. This was very different from the effect of the first canal emanating from the same power-plant at Turkey Point, where a large area had been affected by heated effluents.

‘Trench Connection’ was the first international symposium focusing primarily on the hadal zone (depths greater than 6000 m). It was held at the University of Tokyo's Atmosphere and Ocean Research Institute in November 2010. The symposium was successful in having attracted an international collective of scientists and engineers to discuss the latest developments in the exploration and understanding of the deepest environments on Earth. The symposium sessions were categorized into three themes: (i) new deep-submergence technology; (ii) trench ecology and evolution; and (iii) the physical environment. Recent technological developments have overcome the challenges of accessing the extreme depths, which have in turn prompted an international renewed interest in researching physical and biological aspects of the hadal ecosystems. This bringing together of international participants from different disciplines led to healthy discussions throughout the symposium, providing potential opportunities and realizations of where the future of unravelling hadal ecology lies. Hadal science is still at relatively rudimentary levels compared with those of shallower marine environments; however, it became apparent at the symposium that it is now an ever-expanding scientific field.

Atualmente, o serviço de emergência psiquiátrica (SEP) possui papel fundamental na rede de serviços de saúde mental brasileira. Dele depende, muitas vezes, a definição de uma boa ou má evolução dos quadros psiquiátricos recém iniciados. Este artigo expõe conceitos e dados gerais sobre os SEP, apresenta sua situação atual, mundial e brasileira, e analisa tendências e propostas sobre medidas de planejamento e estruturação dos SEP. Experiências e modelos são analisados como possibilidades de mudanças nos SEP. Como conclusão, os autores salientam a importância da articulação e efetiva execução das prioridades na organização dos SEP no âmbito do Sistema Único de Saúde.

Methodological Approaches

The use of drones to study marine animals shows promise for the examination of numerous aspects of their ecology, behaviour, health and movement patterns. However, the responses of some marine phyla to the presence of drones varies broadly, as do the general operational protocols used to study them. Inconsistent methodological approaches could lead to difficulties comparing studies and can call into question the repeatability of research. This review draws on current literature and researchers with a wealth of practical experience to outline the idiosyncrasies of studying various marine taxa with drones. We also outline current best practice for drone operation in marine environments based on the literature and our practical experience in the field. The protocols outlined herein will be of use to researchers interested in incorporating drones as a tool into their research on marine animals and will help form consistent approaches for drone-based studies in the future.
