Exploring Global Research Trends in Mangrove Ecosystems: A Bibliometric Analysis of Key Issues and Future Directions (1996–2022)

Land Degradation and Development, Journal Year: 2025, Volume and Issue: unknown

Published: March 3, 2025

ABSTRACT Amid escalating global climate change and environmental degradation, mangrove ecosystems face challenges like rapid biodiversity loss, intensified human activities, invasive alien species, recurrent natural disasters. This highlights the urgent necessity for more research informed conservation strategies. Our study meets this need by using advanced bibliometric techniques to analyze trends, evolution, gaps from 1996 2022. It aims bridge knowledge gap providing a comprehensive understanding of dynamics, interdisciplinary integration, geographical distribution, future priorities. The presents thorough analysis over 14,534 multidisciplinary scientific publications covering ecology, forestry, oceanography, management. findings, based on both quantitative qualitative methods, show that: (1) 26‐year is split into two phases: 1996–2008 as initial exploration stage 2009–2022 significant leap stage.in. literature volume surged, especially in 2009 when article count leaped 32 543, signaling start growth research; (2) These studies reflect drawing science, marine/freshwater biology, plant molecular with particular emphasis marine freshwater ecology; (3) China US lead, 3,246 2,671 publications, making up 22.33% 18.38%, respectively.

Ecological thresholds and transformations due to climate change: The role of abiotic stress

Ecosphere, Journal Year: 2025, Volume and Issue: 16(4)

Published: April 1, 2025

Abstract An ecological threshold is the point at which a comparatively small environmental change triggers an abrupt and disproportionately large response. In face of accelerating climate change, there concern that ecosystem transformations will become more widespread as critical thresholds are crossed. There has been ongoing debate, however, regarding prevalence across natural world. While ubiquitous in some ecosystems, have difficult to detect others. Some studies even concluded responses uncommon world overly emphasized literature. As ecologists who work ecosystems chronically exposed high abiotic stress, we consider be concepts can greatly advance understanding inform management. But quantifying challenging, if not impossible, without data strategically collected for purpose. Here, present conceptual framework built upon linkages between climate‐driven responses, risk transformation. We also simple approach stress gradients. hypothesize especially influential where autotroph diversity low foundation species play prominent role. Abiotic conditions these environments often near physiological tolerance limits species, means changes trigger landscape‐level transformations. Conversely, alleviation allow thrive spread into previously inhospitable locations. provide examples this behavior from four high‐stress environments: coastal wetlands, coral reefs, drylands, alpine ecosystems. Our overarching aim review clarify strong relationships thresholds, transformation under change.

Patterns in the chaos: Scale and the spatiotemporal dynamics of coral reef fish assemblages on the Great Barrier Reef

Ecosphere, Journal Year: 2025, Volume and Issue: 16(5)

Published: May 1, 2025

Abstract In the Anthropocene, understanding and managing ecological communities requires characterization of natural spatiotemporal ecosystem dynamics. Complex ecosystems may appear chaotic unstructured, making long‐term monitoring programs with hierarchical sampling designs ideal for investigating patterns at multiple scales. Here, we use a dataset spanning entire Great Barrier Reef (GBR) decades to determine spatial distribution abundance, how these change through time, in 233 reef‐associated fish species. Community composition was strongly structured by position across continental shelf, distinct inner outer shelf assemblages. Latitudinal differences were smaller, except distinctive assemblages southernmost Swain Capricorn‐Bunker regions. GBR‐wide summaries total density species richness did not show directional shifts, it only after analyzing metrics subregional scale that wider range temporal oscillations identified, indicating responses perturbations require examination smaller than GBR Within most subregions (65%), has undergone clear ongoing shift away from community identified 1990s. These changes generally due reduction numbers coral‐dependent an increased dominance grazers generalists. Among species, there have been more “winners” “losers” whole GBR, but this masks tendency reefs central over time. on are dynamic recovery potential disturbance events. Despite some pervasive community‐level shifts last decades, biogeographic characteristics each subregion remain intact. We pose question whether is reasonable expect highly reach relatively stable “climax community,” posit answer scale‐dependent and, currently resolved scale, which stakeholders decision‐makers operate.

Ongoing Range Shift of Mangrove Foundation Species: Avicennia germinans and Rhizophora mangle in Georgia, USA

Ongoing climate change is leading to shifting vegetation patterns in coastal areas worldwide. One such shift the ability of tropical species establish and survive farther north than they would have past. A well-studied example this tropicalization expansion mangroves at marsh-mangrove ecotone, thought be controlled by a decrease extreme freeze events SE USA. However, accurate mangrove distribution data their poleward limit region currently lacking. Here, we report information collected from targeted surveys along Atlantic coasts Florida Georgia We document both Avicennia germinans Rhizophora mangle individuals naturally occuring Georgia, USA, previous reports more 23 km (A. germinans) almost 80 (R. mangle), respectively. Results highlight lack distributional under-sampled region, need for additional study species-specific physiology tolerance, especially R. mangle which exhibited surprising resilience responses events. These will crucial validate models showing northern mangroves. Knowing where established associated conditions that allowed establishment help inform ecotonal shifts foundation are expanding, giving managers researchers needed insight as current landscapes change.
