Climate-driven changes in biotic interactions can profoundly alter ecological communities, particularly when they impact foundation species. In marine systems, herbivory and the consequent loss of dominant habitat forming species result dramatic community phase shifts, such as from coral to macroalgal dominance tropical fish decreases, algal forests ‘barrens’ temperate urchin grazing increases. Here, we propose a novel phase-shift away caused by herbivores extending their range into regions....
Significance Most studies of the impact global warming focus on direct physiological impacts climate change. However, is shifting distribution many species and leading to novel interactions between previously separated that have potential transform entire ecological communities. This study shows an increase in proportion warmwater (“tropicalization”) as oceans warm increasing fish herbivory kelp forests, contributing their decline subsequent persistence alternate “kelp-free” states. These...
Kelp forests dominate the rocky coasts of temperate Australia and are foundation Great Southern Reef. Much like terrestrial forests, these marine create complex habitat for diverse communities flora fauna. also support coastal food-webs valuable fisheries provide a suite additional ecosystem services. In many regions around world, kelp in decline due to ocean warming, overgrazing, pollution. One potential tool conservation management important ecosystems is restoration, science practice...
Abstract While marine kelp forests have provided valuable ecosystem services for millennia, the global ecological and economic value of those is largely unresolved. Kelp are diminishing in many regions worldwide, efforts to manage these ecosystems hindered without accurate estimates that provide human societies. Here, we present a estimate potential three key - fisheries production, nutrient cycling, carbon removal by six major forest forming genera ( Ecklonia, Laminaria, Lessonia,...
Despite advances in sequencing, lack of standardization makes comparisons across studies challenging and hampers insights into the structure function microbial communities multiple habitats on a planetary scale. Here we present multi-omics analysis diverse set 880 community samples collected for Earth Microbiome Project. We include amplicon (16S, 18S, ITS) shotgun metagenomic sequence data, untargeted metabolomics data (liquid chromatography-tandem mass spectrometry gas chromatography...
Interactions between hosts and associated microbial communities can fundamentally shape the development ecology of 'holobionts', from humans to marine habitat-forming organisms such as seaweeds. In systems, planktonic community structure is mainly driven by geography related environmental factors, but large-scale drivers host-associated are largely unknown. Using 16S-rRNA gene sequencing, we characterized 260 seaweed-associated bacterial archaeal on kelp Ecklonia radiata three...
Abstract Coral cover on reefs is declining globally due to coastal development, overfishing and climate change. Reefs isolated from direct human influence can recover natural acute disturbances, but little known about long term recovery of experiencing chronic disturbances. Here we investigate responses bleaching disturbances turbid off Singapore, at two depths over a period 27 years. declined there were marked changes in coral benthic community structure during the first decade monitoring...
Global habitat deterioration of marine ecosystems has led to a need for active interventions halt or reverse the loss ecological function. Restoration historically been key tool and restore functions, but extent which this will be sufficient under future climates is uncertain. Emerging genetic technologies now provide ability restoration proactively match adaptability target species predicted environmental conditions, opens up possibility boosting resistance stress in degraded threatened...
Degradation of natural habitats due to urbanization is a major cause biodiversity loss. Anthropogenic impacts can drive phase shifts from productive, complex ecosystems less desirable, diverse systems that provide fewer services. Macroalgae are the dominant habitat-forming organisms on temperate coastlines, providing habitat and food entire communities. In recent decades, there has been decline in macroalgal cover along some urbanised shorelines, leading shift algal forests more simple turf...
Climate change is driving global declines of marine habitat-forming species through physiological effects and changes to ecological interactions, with projected trajectories for ocean warming acidification likely exacerbate such impacts in coming decades. Interactions between habitat-formers their microbiomes are fundamental host functioning resilience, but how relationships will future conditions largely unknown. We investigated independent interactive on a large brown seaweed, the kelp...
Abstract Incidence, or compositional, matrices are generated for a broad range of research applications in biology. Zeta diversity provides common currency and conceptual framework that links incidence‐based metrics with multiple patterns interest biology, ecology, biodiversity science. It quantifies the variation species (or OTU ) composition assemblages cases) space time, to capture contribution full suite narrow, intermediate, wide‐ranging biotic heterogeneity.

Anthropogenic activities have caused profound changes globally in biodiversity, species interactions and ecosystem functions services. In terrestrial systems, restoration has emerged as a useful approach to mitigate these changes, is increasingly recognised tool fortify ecosystems against future disturbances. marine also gaining traction management tool, but it still comparatively scant underdeveloped relative environments. Key coastal habitats, such seaweed forests seagrass meadows are...
Host-microbe interactions play crucial roles in marine ecosystems. However, we still have very little understanding of the mechanisms that govern these relationships, evolutionary processes shape them, and their ecological consequences. The holobiont concept is a renewed paradigm biology can help to describe understand complex systems. It posits host its associated microbiota with which it interacts, form holobiont, be studied together as coherent biological functional unit biology, ecology,...
It is commonly held that there a fundamental relationship between genome size and error rate, manifest as notional “error threshold” sets an upper limit on sizes. The sizes of RNA viruses, which have intrinsically high mutation rates due to lack mechanisms for correction, must therefore be small avoid accumulating excessive number deleterious mutations will ultimately lead population extinction. proposed exceptions this evolutionary rule are viruses from the order Nidovirales (such...
Despite the significance of marine habitat-forming organisms, little is known about their large-scale distribution and abundance in deeper waters, where they are difficult to access. Such information necessary develop sound conservation management strategies. Kelps main habitat-formers temperate reefs worldwide; however, these habitats highly sensitive environmental change. The kelp Ecklonia radiate major organism on subtidal Australia. Here, we provide ecological data encompassing...
Growing demands for potable water have led to extensive reliance on waterways in tropical megacities. Attempts manage these an environmentally sustainable way generally lack understanding of microbial processes and how they are influenced by urban factors, such as land use rain. Here, we describe the composition functional potential benthic communities from waterway network analyze effects rain perturbations communities. With a sequence depth 3 billion reads 48 samples, metagenomes represent...
In many temperate regions, brown macroalgae fulfil essential ecosystem services such as the provision of structure, fixation nutrients and carbon, production biomass oxygen.Their populations in regions around globe have declined and/ or spatially shifted recent decades.In this review we highlight potential global regional drives these changes, describe status regionally particularly important macroalgal species, capacity interactions among abiotic biotic factors to amplify buffer...
Macroalgal surfaces support abundant and diverse microorganisms within biofilms, which are often involved in fundamental functions relating to the health defence of their seaweed hosts, including algal development, facilitation spore release chemical antifouling. Given these intimate important interactions, environmental changes have potential negatively impact macroalgae by disrupting seaweed-microbe interactions. We used disappearance dominant canopy-forming fucoid Phyllospora comosa from...
Sydney Harbour is a global hotspot for marine and estuarine diversity. Despite its social, economic biological value, the available knowledge has not previously been reviewed or synthesised. We systematically published literature consulted experts to establish our current understanding of Harbour’s natural systems, identify gaps, compare other major estuaries worldwide. Of 110 studies in review, 81 focussed on ecology biology, six chemistry, 10 geology 11 oceanography. Subtidal rocky reef...
Host-associated microbial communities play a fundamental role in the life of eukaryotic hosts. It is increasingly argued that hosts and their microbiota must be studied together as 'holobionts' to better understand effects environmental stressors on host functioning. Disruptions host-microbiota interactions by can negatively affect performance survival. Substantial ecological impacts are likely when affected habitat-forming species (e.g., trees, kelps) underpin local biodiversity. In marine...
