Subcellular view of host–microbiome nutrient exchange in sponges: insights into the ecological success of an early metazoan–microbe symbiosis

Meggie Hudspith, Laura Rix, Michelle Achlatis, Jeremy Bougoure, Paul Guagliardo, Peta L. Clode, Nicole S. Webster, Gerard Muyzer, Mathieu Pernice & Jasper M. De Goeij
Background: Sponges are increasingly recognised as key ecosystem engineers in many aquatic habitats. They play an important role in nutrient cycling due to their unrivalled capacity for processing both dissolved and particulate organic matter (DOM and POM) and the exceptional metabolic repertoire of their diverse and abundant microbial communities. Functional studies determining the role of host and microbiome in organic nutrient uptake and exchange, however, are limited. Therefore, we coupled pulse-chase isotopic tracer techniques with...

Large-scale interventions may delay decline of the Great Barrier Reef

Scott Condie, Ken Anthony, Mark Baird, Roger Beeden, Daniel Harrison, Éva Plagányi, Russell Babcock, Cameron Fletcher, Rebecca Gorton, Alistair Hobday & David Westcott
On the iconic Great Barrier Reef (GBR) the cumulative impacts of tropical cyclones, marine heatwaves and regular outbreaks of coral-eating crown-of-thorns starfish (CoTS) have severely depleted coral cover. Climate change will further exacerbate this situation over the coming decades unless effective interventions are implemented. Evaluating the efficacy of alternative interventions in a complex system experiencing major cumulative impacts can only be achieved through a systems-modeling approach. We have evaluated combinations of interventions using a coral...

Data from: Population genetics of a broadcast-spawning coral across a tropical-temperate transition zone reveals regional differentiation and isolation of high-latitude reefs

Richard Evans, Luke Thomas, W. Jason Kennington, Nicole Ryan, Nerida Wilson, Zoe Richards, Ryan Lowe & Chenae Tuckett
Aim: Genetic connectivity is a key component of species resilience to climate change in terms of recovery capacity following disturbance and capacity to disperse to novel locations as the climate warms and isotherms shift poleward. We aimed to strengthen our understanding of resilience in this context by characterizing patterns of connectivity and genetic diversity in a broadcast spawning coral across a tropical-temperate transition zone. We hypothesize genetic differentiation between tropical and temperate populations and decreasing...

Peaceful coexistence between people and deadly wildlife: why are recreational users of the ocean so rarely bitten by sea snakes?

Vinay Udyawer
1) Research on interactions between humans and deadly snakes has focused on situations that result in high rates of snakebite; but we can also learn from cases where snakes and people coexist peacefully. For example, coastal bays near Noumea, in the Pacific archipelago of New Caledonia, are used by thousands of tourists and snakes, but bites are rare. 2) Our long-term studies clarify reasons for this coexistence. Although 97% of snakes encountered in standardized snorkel...

Species-level coral bleaching data for Maldives and GBR

Paul Muir, Terence Done & David Aguirre
Response to coral bleaching for 7368 coral colonies exposed to similar levels of temperature stress at a similar depth of occurrence and similar subsequent mortality. Collected in situ following moderate thermal bleaching events in the GBR in 2002 and the Maldives in 2016. Data gives species, site, depth of occurence and bleaching response which was scored by tissue colour.

Environmental DNA reveals a multi-taxa biogeographic break across the Arabian Sea and Sea of Oman

Joseph DiBattista, Michael Berumen, Mark Priest, Maarten De Brauwer, Darren Coker, Tane Sinclair-Taylor, Amanda Hay, Gerd Bruss, Shawky Mansour, Michael Bunce, Christopher Goatley, Matthew Power & Alyssa Marshell
Environmental DNA (eDNA) is increasingly being used to assess community composition in marine ecosystems. Applying eDNA approaches across broad spatial scales now provide the potential to inform biogeographic analyses. However, to date, few studies have employed this technique to assess broad biogeographic patterns across multiple taxonomic groups. Here, we compare eDNA-derived communities of bony fishes and invertebrates, including corals and sponges, from 15 locations spanning the entire length of the Omani coast. This survey includes...
