Multi-scale records of reef development and condition provide context for contemporary changes on inshore reefs [PDF]

open access: yes, 2016
Comparisons between historical and contemporary photographs of coral reef flats from the inshore Great Barrier Reef (GBR) have been cited by various authors and agencies as evidence of reef degradation since European settlement and have been presented as

Breaking down seagrass fragmentation in a marine heatwave impacted World Heritage Area

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Habitat fragmentation can exacerbate the impacts of habitat loss but is rarely quantified in marine environments. Using satellite‐derived habitat maps, we identify widespread seagrass fragmentation following a marine heatwave that contributed to a dramatic shift in seascape structure in the Shark Bay World Heritage Area.

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Evaluating methods for high‐resolution, national‐scale seagrass mapping in Google Earth Engine

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Marine habitat mapping using satellite imagery can provide baseline and monitoring data across large spatial scales and in remote locations globally. This study evaluates how key methodological choices influence the accuracy of open‐source (for non‐commercial use), cloud‐based satellite mapping workflows for seagrass meadows in the Maldives.

Impact of parameterization in multiple acoustic index comparisons: practical cases in terrestrial and underwater soundscapes

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Parameter choices in acoustic analyses (sampling frequency, FFT size and window overlap) strongly influence multivariate soundscape separation. Using terrestrial and coral reef recordings, we show that these settings can exaggerate or mask ecological differences, emphasizing the need for parameter sensitivity testing and transparent reporting in ...

Assessment of fish populations and habitat on Oculina Bank, a deep-sea coral marine protected area off eastern Florida [PDF]

open access: yes, 2009
A portion of the Oculina Bank located off eastern Florida is a marine protected area (MPA) preserved for its dense populations of the ivory tree coral (Oculina varicosa), which provides important habitat for fish.

Evaluating land–sea linkages using land cover change and coral reef monitoring data: A case study from northeastern Puerto Rico

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Land cover change that leads to increased nutrient and sediment runoff is an important driver of change in coral reef ecosystems. In this study, we combined satellite remote sensing and field monitoring to assess concomitant changes in watershed land cover and coral cover in northeastern Puerto Rico in 2000–2015.

How spatial feedbacks between institutional and ecological patterns drive landscape dynamics in peri-urban commons

open access: yesEcology and Society
Rapid urbanization is a critical landscape transition that impacts biodiversity, ecosystem goods and services, and social sustainability. Urbanizing locations may follow different ecological trajectories, with very different consequences for future ...
