The mangrove CO 2 pump: Tidally driven pore‐water exchangeNARA Subscribed
Atmospheric carbon dioxide (CO 2 ) is fixed by mangrove vegetation and stored in its biomass and sediments. Part of the sediment carbon can be exported to coastal waters via tidally driven pore‐water exchange. Here, we quantify pore water‐derived dissolved CO 2 export using in situ, high‐resolution observations of 222 Rn and CO 2 over a spring‐neap tidal cycle in a mangrove‐fringed estuary (Coffs Creek, Australia). 222 Rn‐deri...
Organisms are locally adapted when members of a population have a fitness advantage in one location relative to conspecifics in other geographies. For example, across latitudinal gradients, some organisms may trade off between traits that maximize fitness components in one, but not both, of somatic maintenance or reproductive output. Latitudinal gradients in life history strategies are traditionally attributed to environmental...
Gas transfer velocities ( k ) of CO 2 and CH 4 were determined from 209 deployments of a newly designed floating chamber in six mangrove dominated estuaries in Australia and the United States to estimate mangrove system specific k . k 600 ‐ CO 2 and k 600 ‐ CH 4 ( k normalized to the Schmidt number of 600) varied greatly within and between mangrove creeks, ranging from 0.9 cm h −1 to 28.3 cm h −1 . The gas transfer velocity co...
Validation of diagnostic assays to screen broodstock for Flavobacterium psychrophilum infectionsNARA Subscribed
It is hypothesized that the frequency of bacterial coldwater disease outbreaks can be reduced through the detection of the aetiologic agent, Flavobacterium psychrophilum , in broodstock followed by culling of eggs from heavily infected broodstock. Before a culling programme can be instituted, however, it is necessary to determine the sensitivity and specificity of existing assays for the detection of F. psychrophilum . In this...
Association of red‐mark syndrome with a Rickettsia ‐like organism and its connection with strawberry disease in the USANARA Subscribed
Red‐mark syndrome (RMS), a disease seen mostly in rainbow trout, Oncorhynchus mykiss , is of unknown aetiology. The research presented here indicates the presence of an intracellular bacterium in RMS‐affected fish. A positive reaction was observed using immunohistochemistry (IHC) with skin lesions, liver, kidney and spleen of affected fish sampled from several locations within the United Kingdom using two different polyclonal...
Flavobacterium psychrophilum is the aetiological agent of rainbow trout fry syndrome and bacterial cold water disease. This study examined the genetic diversity of F. psychrophilum isolates retrieved from multiple epizootics at rainbow trout, Oncorhynchus mykiss , rearing facilities and from spawning coho salmon, O. kisutch . A total of 139 isolates were confirmed as F. psychrophilum by PCR assay and were further typed using p...
