Maria Island Secondary Productivity Data
Data were collected from 28 artificial reefs varying in size and supporting different densities of transplanted kelp (Ecklonia radiata). We used rope fibre habitats (RFHs)... -
Management options to minimise formation of urchin barrens: kelp lines -...
Linear video transects (40m total length; 20m into barrens and 20m into kelp from original fixed marker on the benthos) were used to assess changes in kelp growth in several... -
Phenotypic plasticity in habitat-forming seaweeds subject to latitudinal transplant
The phenotypic plasticity of habitat-forming seaweeds was investigated with a transplant experiment in which juvenile Ecklonia radiata and Phyllospora comosa were transplanted... -
Top-down sea urchin overgrazing overwhelms bottom-up nutrient stimulation of...
Biogenic marine habitats are increasingly threatened by a multitude of human impacts, and temperate coasts in particular are exposed to progressively more intense and frequent... -
Management options to minimise formation of urchin barrens: using belt...
Belt transect surveys (50m) were used to monitor the benthic community structure through time at experimental (lobster additions/ research reserve sites or abalone diver urchin... -
Maria island artificial reef fish data
Data describing post-recruit (adult) fish assemblages and the abundance of recruiting cryptobenthic species associated with 28 artificial reefs of different sizes and supporting... -
Kelp habitat density and composition from underwater video
Annotations of canopy forming seaweed derived from towed video at selected key abalone blocks along the east coast of Tasmania. The purpose of the study was to examine the patch... -
PCR genetic screening for presence of sea urchin DNA in rock lobster faecal samples
Data is PCR amplification results of southern rock lobster (Jasus edwardsii) faecal material tested for sea urchin DNA (using unique primers for Centrostephanus rodgersii and... -
Drift-kelp suppresses foraging movement of overgrazing sea urchins
Sea urchins have the capacity to destructively overgraze kelp beds and cause a wholesale shift to an alternative and stable ‘urchin barren’ state. However, their destructive... -
Transplanted kelp reefs at Maria Island, TAS, Australia
Data accompanying Layton et al. 2019, Resilience and stability of kelp forests: the importance of patch dynamics and environment-engineer feedbacks. PLOS ONE. To explore how... -
Range expansion of the sea urchin Centrostephanus rodgersii leads to loss of...
The long spined sea urchin Centrostephanus rodgersii (Diadematidae) has recently undergone poleward range expansion to eastern Tasmania (southeast Australia). This species is... -
Ecophysiology of three habitat-forming seaweeds across a depth and...
Seasonal patterns in the in situ ecophysiology of the common habitat-forming seaweeds Ecklonia radiata, Phyllospora comosa, and Macrocystis pyrifera were investigated at... -
Surveys of sea urchins (Centrostephanus rodgersii and Heliocidaris...
Quantitative surveys were undertaken at five sites in the Kent Group, north eastern Tasmania (Murray Pass, Winter Cove, Little Squally Cove,and southern end of Erith Island) by... -
Macroinvertebrates associated with artificial reefs at Maria Island
The abundance of macroinvertebrates associated with 28 experimental artificial reefs supporting different patch sizes and density of kelp (Ecklonia radiata) off Maria Island,... -
Maria Island mussel and microphytobenthic algal data
The recruitment of mussels and microphytobenthic (MPB) algae to 28 experimental artificial reefs supporting different patch sizes and density of kelp (Ecklonia radiata) off... -
Community assembly in marine macrofauna communities
Community assembly in macrofauna communities developed in artificial kelp holdfasts was monitored at 1-month intervals over a 13 month period using a sampling design that used...
