Temporal variation in a temperate cryptobenthic fish assemblage at the Arrábida Marine Park (Portugal) was assessed by visual surveys during 2002 and 2003. A total of 9596 fish from 11 families and 30 species was recorded. There were no changes in structure or density at the assemblage level between years, whereas diversity changed significantly due to a higher number of abundant species in the second year. A similar seasonal trend was found between years, with a significant overall density increase in autumn. This is partially explained by the arrival of new recruits of some of the most abundant species in the assemblage. Assemblage diversity and structure also changed across seasons. A group of species encompassing Gobius xanthocephalus, Tripterygion delaisi, Parablennius pilicornis, Gobius paganellus, Lepadogaster candollii and Lepadogaster spp. were analysed in detail. The temporal patterns of two of the most abundant species, G. xanthocephalus and T. delaisi, mimicked the overall temporal patterns of the assemblage. We suggest that the inter-annual stability in density of this subtidal fish assemblage may be similar to what has been reported for the intertidal and that strong post-settlement processes are probably shaping this assemblage.

Abstract Watershed has played an important source of ecosystem services (ES). The Krueng Peusangan watershed (KPW) is considered to be the “lungs” and ecological border in the central region of Aceh, Indonesia. This study aims to monitor landscape patterns in the watershed area of 2009-2019 and to predict changes in 2039 and their relationship with infiltration. The selection of this research area is due to the notion that KPW is one of the numerously deforested watersheds in the country. Temporal spatial monitoring of landscape (land use/cover, LUC) patterns are required to inform policy and support future spatial management planning towards sustainability. Landscape patterns changes in KPW, including the extent of loss and addition of forest over the last few years, have not been quantified. In constructing the regional development policies, information regarding the effects of landscape changes and climatic patterns on ecosystem services is essential. Therefore, the knowledge development of this relationship is encouraged. The comparison value between potential and actual infiltration could identify the watershed category. The upstream area of KPW is classified as a significantly critical watershed due to LUC changes. Therefore, it is deemed necessary to improve the absorption zone for the continuation of groundwater protection.

Snapper is a significant fishery species in Australasia whose movement behaviour remains poorly understood. This was addressed in the present study at the within-region scale using acoustic telemetry in the Gulf St Vincent, South Australia. Over 3 years from May 2011, 54 snapper were monitored throughout ~160km2 using 41 acoustic receivers. The dispersion of >500000 detections varied in space and time, reflecting three types of space use, dependent on different types of movement behaviour. One station, near a large shipwreck, accounted for 67.8% of all detections, particularly during winter, when fish were sedentary and site attached. In spring, the fish dispersed throughout the study area to different habitats and, through summer, occupied different larger restricted areas than used in winter. Snapper were highly mobile and demonstrated systematic behaviour at several temporal scales. They moved linear distances of up to ~100km and could achieve tens of kilometres in a day in episodic movements. Through the year, their activity was distributed across areas of hundreds of square kilometres. The regional spatial management regimen was assessed against this enhanced understanding of movement behaviour. A new marine park sanctuary zone that encompassed the shipwreck was appropriately located, but possible benefits of a nearby spatial spawning closure area appear limited.
