Climate-assisted persistence of tropical fish vagrants in temperate marine ecosystems
<p>Rising temperatures and extreme climatic events are propelling tropical species into temperate marine ecosystems, but not all species can persist. Here, we used the heatwave-driven expatriation of tropical black rabbitfish (<i>Siganus fuscescens</i>) to the temperate environments of Western Australia to assess the ecological and evolutionary mechanisms that may entail their persistence. Population genomic assays for this rabbitfish indicated little genetic differentiation between tropical residents and vagrants to temperate environments due to high migration rates, which were likely enhanced by the marine heatwave. DNA metabarcoding revealed a diverse diet for this species based on phytoplankton and algae, as well as an ability to feed on regional resources, including kelps. Irrespective of future climate scenarios, these macroalgae-consuming vagrants may self-recruit in temperate environments and further expand their geographic range by 2100. This expansion may compromise the health of the kelp forests that form Australia's Great Southern Reef. Overall, our study demonstrates that projected favourable climatic conditions, continued large-scale genetic connectivity between populations, and diet versatility are key for tropical range-shifting fish to establish in temperate ecosystems.</p>

Data on short-term temperature modulated dilution experiments and summary of dilution experiments in (sub)tropical waters
<p>Two datasets were compiled for estimating and comparted the temperature sensitivity of phytoplankton growth rate within vs across communities.</p> <p>One dataset contains the data of short-term temperature modulated dilution experiments conducted at three subtropical coastal sites for one year. In each experiment, the phytoplankton community growth rates were estimated at five different temperatures via the dilution approach. </p> <p>Another dataset contains the phytoplankton community growth rates in (sub)tropical waters estimated by the dilution approach, collected from related literature. </p> <p> </p>

Tourism and urban development as drivers for invertebrate diversity loss on tropical islands
<p>Oceanic islands harbour a disproportionately high number of endemic and threatened species. Rapidly growing human populations and tourism are posing an increasing threat to island biota, yet the ecological consequences of these human land uses on small oceanic island systems have not been quantified. Here, we investigated and compared the impact of tourism and urban island development on ground-associated invertebrate biodiversity and habitat composition on oceanic islands. To disentangle tourism and urban land uses, we investigated Indo-Pacific atoll islands, which either exhibit only tourism or urban development, or remain uninhabited. Within the investigated system, we show that species richness, abundance, and Shannon diversity of the ground-associated invertebrate community are significantly decreased on islands used for tourism and on islands with urban development, relative to uninhabited islands. Remote-sensing-based spatial data suggests that habitat fragmentation and a reduction in vegetation density are having significant effects on biodiversity on urban islands, whereas land use/ cover changes could not be linked to the documented biodiversity loss on tourist islands. This offers first direct evidence for a major terrestrial invertebrate loss on remote oceanic islands due to different human land uses with yet unforeseeable long-term consequences for the stability and resilience of oceanic island ecosystems.</p>
