Rehabilitated and restored mangrove ecosystems have important ecological, economic, social values for coastal communities. Although a sine qua non of successful rehabilitation or restoration projects is accurate attention to local hydrology basic biology trees their associated fauna, long-term success depends on far more axes, each with own challenges. Rehabilitation projects: are planned, designed, executed, managed by people diverse backgrounds different scientific socio-political agendas; need be responsive these multiple stakeholders agents who hold values; often influenced laws treaties spanning international scales; must able adapt evolve both geomorphologically socioeconomically over decades-to-centuries in the context rapidly changing climate. We view challenges as opportunities innovative approaches that engage new larger constituencies.

Published: Jan. 7, 2024

Mangroves, the distinctive coastal ecosystems of tropics and sub-tropics, serve as crucial intersections between terrestrial marine environments. In this review, we delve into manifold roles mangroves, showcasing their significance in environmental engineering sustainable ecosystem practices. Historically undervalued, mangroves have undergone a renaissance perception, with increasing recognition indispensable ecological services, ranging from protection blue carbon sequestration to fostering biodiversity supporting fisheries. As explore potential phytoremediation, bioremediation, urban resilience, ecosystem-based adaptation, synergistic relationships resident microorganisms are highlighted, offering innovative avenues for restoration. Additionally, review underscores importance collaborative partnerships mangrove conservation, emphasizing need harmonized approach stakeholders. an era marked by rapid changes, accentuates multifunctional capability nature's architects, advocating conservation integration management strategies.

Global impacts of marine heatwaves on coastal foundation species

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: June 13, 2024

Abstract With increasingly intense marine heatwaves affecting nearshore regions, foundation species are coming under increasing stress. To better understand their impacts, we examine responses of critical, habitat-forming (macroalgae, seagrass, corals) to in 1322 shallow coastal areas located across 85 ecoregions. We find compelling evidence that intense, summer play a significant role the decline globally. Critically, detrimental effects increase towards warm-range edges and over time. also identify several ecoregions where don’t respond heatwaves, suggestive some resilience warming events. Cumulative heatwave intensity, absolute temperature, location within species’ range key factors mediating impacts. Our results suggest many ecosystems losing species, potentially impacting associated biodiversity, ecological function, ecosystem services provision.

Network ecology is an emerging field that allows researchers to conceptualize and analyse ecological networks their dynamics. Here, we focus on the dynamics of in response environmental changes. Specifically, formalize how network topologies constrain systems into a unifying framework refer as 'ecological framework'. This stresses interplay between species interaction spatial layout habitat patches key identifying which properties (number weights nodes links) trade-offs among them are needed maintain interactions dynamic landscapes.

Environmental disturbances often cause individuals to change their behavior. The behavioral responses can induce a chain of reactions through the network species interactions, via consumptive and trait mediated connections. Given that interactions define ecosystem structure functioning, changes these have ecological repercussions. Here, we explore transmission how influence conditions. We describe underlying mechanisms ultimate impact on including biodiversity ecosystems stability services. explain why some larger than others ecosystems, research should focus interactions.
