Species‐specific processing of fluorescent dissolved organic matter by Caribbean spongesNARA Subscribed
Coral reefs are biodiverse and productive ecosystems that are found in typically oligotrophic environments. Many studies have attempted to explain this paradox by demonstrating that microbial symbionts expand metabolic capabilities of host animals. However, few studies have determined if and how coexisting organisms and their symbiotic microbial communities partition available dissolved organic matter. To address this question...
Geoheritage Values of Ambaji Region, Gujarat: Western IndiaNARA Subscribed
Background As fire regimes are changing and wildfire disasters are becoming more frequent, the term megafire is increasingly used to describe impactful wildfires, under multiple meanings, both in academia and popular media. This has resulted in a highly ambiguous concept. Approach We analysed the use of the term ‘megafire’ in popular media to determine its origin, its developments over time, and its meaning in the public spher...
Two new cryptic species of the freshwater fish genus Gobiomorphus (Gobiiformes: Gobioidei: Eleotridae) in New ZealandNARA Subscribed
We describe two new species in the genus Gobiomorphus , a radiation of fresh and brackish water gudgeons known from Australia and New Zealand. These species are a prominent component of New Zealand's freshwater ichthyofauna and most are widely distributed throughout both the North and South Islands. Two of the inland species, G. breviceps and G. basalis, are composed of disjunct northern and southern populations that are disti...
Sponge–Microbe Interactions on Coral Reefs: Multiple Evolutionary Solutions to a Complex EnvironmentOA Marine
Marine sponges have been successful in their expansion across diverse ecological niches around the globe. Pioneering work attributed this success to both a well-developed aquiferous system that allowed for efficient filter feeding on suspended organic matter and the presence of microbial symbionts that can supplement host heterotrophic feeding with photosynthate or dissolved organic carbon. We now know that sponge-microbe inte...
Complex interactions between marine sponges and their symbiotic microbial communitiesNARA Subscribed
To investigate the importance of symbiont‐derived nutrition to host sponges, we coupled manipulative shading experiments with stable isotope analyses of isolated symbiont and host cell fractions. Experiments were conducted with four common reef sponges: Aplysina cauliformis , A. fulva , Neopetrosia subtriangularis , and Niphates erecta . The sponge N. erecta lacks photosymbionts, had a higher growth rate under shaded condition...
Aim To determine biogeographical patterns in five closely related species in the fish genus Hypseleotris , and to investigate the relative roles of drainage divide crossings and movement during lowered sea levels between drainage basins and biogeographical provinces based on the phylogeographical patterns within the group. The high degree of overlap in the distributions and ecology of these species makes them ideal candidates...
