Coral reef ecosystem services in the Anthropocene

Abstract Coral reefs underpin a range of ecosystem goods and services that contribute to the well‐being millions people. However, tropical coral in Anthropocene are likely be functionally different from past. In this perspective piece, we ask, what does mean for provision reefs? First, provide examples provisioning, regulating, cultural supporting underpinned by reef ecosystems. We conclude service research has lagged behind multidisciplinary advances broader science, such as an explicit recognition interactions between social ecological systems services. Second, drawing on tools functional ecology, outline how these social–ecological relationships can incorporated into mechanistic understanding might used anticipate future changes Finally, explore emergence novel services, example tropicalized coastlines, or through changing technological connections reefs. Indeed, when conceived coming system dynamics, novelty emerge elements people ecosystem. This synthesis literature suggests field is poorly prepared understand anticipated Anthropocene. A new agenda needed better connects ecology provision. should embrace more holistic approaches research, recognizing them co‐produced ecosystems society.

Integrating structure-from-motion photogrammetry with geospatial software as a novel technique for quantifying 3D ecological characteristics of coral reefs

PeerJ, Journal Year: 2015, Volume and Issue: 3, P. e1077 - e1077

Published: July 7, 2015

The structural complexity of coral reefs plays a major role in the biodiversity, productivity, and overall functionality reef ecosystems. Conventional metrics with 2-dimensional properties are inadequate for characterization complexity. A 3-dimensional (3D) approach can better quantify topography, rugosity other characteristics that play an important ecology communities. Structure-from-Motion (SfM) is emerging low-cost photogrammetric method high-resolution 3D topographic reconstruction. This study utilized SfM reconstruction software tools to create textured mesh models at French Frigate Shoals, atoll Northwestern Hawaiian Islands. reconstructed orthophoto digital elevation model were then integrated geospatial order pertaining resulting data provided physical colonies combined live cover accurately characterize as living structure. structure be physiological ecological parameters future research develop reliable ecosystem improve capacity monitor changes health function

Coral reef ecosystem functioning: eight core processes and the role of biodiversity

Frontiers in Ecology and the Environment, Journal Year: 2019, Volume and Issue: 17(8), P. 445 - 454

Published: July 30, 2019

Coral reefs are in global decline. Reversing this trend is a primary management objective but doing so depends on understanding what keeps desirable states (ie “functional”). Although there evidence that coral thrive under certain conditions (eg moderate water temperatures, limited fishing pressure), the dynamic processes promote ecosystem functioning and its internal drivers community structure) poorly defined explored. Specifically, despite decades of research suggesting positive relationship between biodiversity across biomes, few studies have explored reef systems. We propose practical definition functioning, centered eight complementary ecological processes: calcium carbonate production bioerosion, herbivory, secondary predation, nutrient uptake release. Connecting species niches, functional diversity communities, rates key can provide novel, quantitative dependence communities will chart transition Anthropocene. This contribute urgently needed guidance for these important ecosystems.

Urban coral reefs: Degradation and resilience of hard coral assemblages in coastal cities of East and Southeast Asia

Marine Pollution Bulletin, Journal Year: 2018, Volume and Issue: 135, P. 654 - 681

Published: Aug. 1, 2018

Given predicted increases in urbanization tropical and subtropical regions, understanding the processes shaping urban coral reefs may be essential for anticipating future conservation challenges. We used a case study approach to identify unifying patterns of clarify effects on hard assemblages. Data were compiled from 11 cities throughout East Southeast Asia, with particular focus Singapore, Jakarta, Hong Kong, Naha (Okinawa). Our review highlights several key characteristics reefs, including "reef compression" (a decline bathymetric range increasing turbidity decreasing water clarity over time relative shore), dominance by domed growth forms low reef complexity, variable city-specific inshore-offshore gradients, early declines cover recent fluctuating periods acute impacts rapid recovery, colonization infrastructure corals. present hypotheses community dynamics discuss potential ecological engineering corals areas.

Towards an urban marine ecology: characterizing the drivers, patterns and processes of marine ecosystems in coastal cities

Oikos, Journal Year: 2019, Volume and Issue: 128(9), P. 1215 - 1242

Human population density within 100 km of the sea is approximately three times higher than global average. People in this zone are concentrated coastal cities that hubs for transport and trade – which transform marine environment. Here, we review impacts interacting drivers urbanization (resource exploitation, pollution pathways ocean sprawl) discuss key characteristics symptomatic urban ecosystems. Current evidence suggests these systems comprise spatially heterogeneous mosaics with respect to artificial structures, pollutants community composition, while also undergoing biotic homogenization over time. Urban ecosystem dynamics often influenced by several commonly observed patterns processes, including loss foundation species, changes biodiversity productivity, establishment ruderal synanthropes novel assemblages. We potential acclimatization adaptation among taxa, interactive effects climate change urbanization, ecological engineering strategies enhancing By assimilating research findings across disparate disciplines, aim build groundwork ecology a nascent field; challenges future directions new field as it advances matures.

Shifts in coral-assemblage composition do not ensure persistence of reef functionality

Scientific Reports, Journal Year: 2013, Volume and Issue: 3(1)

Published: Dec. 12, 2013

Coral communities are changing rapidly worldwide through loss of coral cover and shifts in species composition. Although many reef-building corals likely to decline, some weedy opportunistic might increase abundance. Here we explore whether the reshuffling can maintain ecosystem integrity functioning. Using four common Caribbean genera modeled rates reef construction complexity. We show that shifting assemblages result rapid losses coral-community calcification rugosity independent changes total abundance corals. These considerably higher than those recently attributed climate change. Dominance patterns seem be most important driver functioning reefs thus, future these ecosystems depend not only on reductions local global stressors, but also maintenance keystone species.
