Predation can strongly influence community structure and ecosystem function, so the loss of key predators can have dramatic ecological consequences, unless other predatory species in the system are capable of playing similar ecological roles. In light of the recent outbreak of sea star wasting disease (SSWD) and subsequent depletion of west coast sea star populations, including those of the key...
The structure of ecological communities reflects a tension among forces that alter populations. Marine ecologists previously emphasized control by locally operating forces (predation, competition, and disturbance), but newer studies suggest that inputs from large-scale oceanographically modulated subsidies (nutrients, particulates, and propagules) can strongly influence community structure and ...
Accepted 25 December 2006 Copyright © EEF ISSN 1399-1183 Limpets are one of the most abundant molluscs in rocky shores. However, the rocky shore is a harsh environment, considering the huge force and impact of waves against the rocks. Additionally, at each tidal cycle, limpets are out of water for considerable period of time, being therefore exposed to high temperature and desiccation stresses....
Intertidal rocky reefs are complex and rich ecosystems that are vulnerable to even the smallest fluctuations in sea level. We modelled habitat loss associated with sea level rise for intertidal rocky reefs using GIS, high-resolution digital imagery, and LIDAR technology at fine-scale resolution (0.1 m per pixel). We used projected sea levels of +0.3 m, +0.5 m and +1.0 m above current Mean Low T...
Abstract The introduction of Pacific oysters to the sedimentary south-eastern North Sea coast and their establishment on intertidal native blue mussel beds has caused development mixed reefs mussels with extensive tidepools. Tidepools have been intensively studied at rocky shores where they show community structures, which usually differ from that surrounding emerging substrates. coasts, howeve...
From microbes to humans, habitat structural complexity plays a direct role in the provision of physical living space, and increased supports higher biodiversity ecosystem functioning across biomes. Coastal development construction artificial shorelines are altering natural landscapes as humans seek socio-economic benefits protection from coastal storms, flooding erosion. In this study, we evalu...
